1.1 Operator’s Manual
Information on this Operator’s Manual
This Operator’s Manual describes how to operate and perform
maintenance on the machine. It provides operating and maintenance
personnel with the necessary knowledge of the machine’s functional
characteristics to ensure safe handling, correct maintenance, inspection
and cleaning, and to ensure that the technical safety regulations for the
machine are complied with.
Your own safety, as well as the safety of others, depends to a great extent
on how the machine is moved and operated. Therefore, carefully read and
understand this Operator’s Manual prior to the first drive. By reading the
Operator’s Manual, the operator familiarizes himself more quickly with the
machine, and uses it more safely and efficiently.
If required, the user/owner of the machine must supplement the
Operator’s Manual with instructions and regulations regarding
environmental protection and national accident prevention regulations.
Operational safety and readiness of the machine do not only depend on
the operator’s skill, but also on maintenance and servicing of the machine.
This is why regular maintenance and servicing is absolutely necessary.
Please refer to chapter – see “Information on cleaning and maintenance”
on page 7-18 for an overview of the maintenance and service work. An
inspection booklet is also supplied with the machine.

in work with or on the machine, for example, with regard to:
• Operation, including setting up, rectifying malfunctions during
operation, maintenance, disposal of auxiliary and operating material,
and disposal of the entire machine.
• Repairs (inspection, maintenance).
• Transportation.
Your dealer and the Wacker Neuson service team will be happy to answer
any questions you may have on this Operator’s Manual.
All technical indications in this Operator’s Manual refer to series models
tested under standard operating conditions for Central Europe and
describe the standard functions of these series models. The equipment

 Introduction 3

Travelling drive
The machine is driven by a diesel engine that powers the steering,
operating and machine-travel hydraulics.
The travel hydraulics drives the transfer gearbox, which transmits the
power to the rear axle and, via the cardan shaft, to the front axle.
The axles are designed as rigid axles.

Brakes
The drive also has the function of a service brake with effect on the front
and rear axles. The brake is activated via the braking-inching pedal.
Furthermore, the drum/disk brake on the differential is operated with the
brake/inching pedal. The parking brake also has effect on this drum/disk
brake.

Steering system
The oscillating articulation is ensured by means of one or two double-
action hydraulic cylinders.

Hydraulic system
The machine is equipped with two hydraulic systems and one single
hydraulic oil reservoir:
- Hydrostatic drive
- Steering and operating hydraulics
The diesel engine permanently drives a hydraulic pump (variable
displacement pump), the oil flow of which is sent to a hydraulic motor
(variable displacement motor) flanged on the transfer gearbox. The force
of the hydraulic motor is transmitted to the rear axle via the transfer
gearbox, and to the front axle via the cardan shaft.
Adjustment is automatic and continuous, but depends on engine speed
and load. The travel speed depends on the engine speed and machine
load. The accelerator pedal controls machine travel, which starts at the
rated engine speed and reaches full speed at maximum engine speed.
Depending on machine load, the output of the variable displacement
pump is automatically reduced to ensure the best possible torque. The
higher the load on the machine (for example during loading work or uphill
machine travel), the more the travel speed is reduced. This type of
machine regulation makes the best possible use of the entire power
range. By controlling the brake-inch pedal (inching = time-delayed; pedal
on the left) it also has its effect on machine regulation by precisely slowing
down the machine to a standstill at any engine speed.
The steering and operating hydraulics are supplied with pressure oil by
hydraulic gear pumps. The gear pump is flanged onto the variable
displacement pump of the drive.
The hydraulic system is equipped with pressure limiting valves, filters and
an oil radiator.

3 Introduction

Cooling system
A combined water/hydraulic oil radiator (for the diesel engine and the
hydraulic oil) is located in the engine compartment. The radiator fan is
driven mechanically by the diesel engine by means of a V-belt.
The indicator lights and gages on the instrument panel of the machine
ensure constant monitoring of the engine and hydraulic oil temperature.

Electrical system
The electrical system operates at a voltage of 12 V. Consumers and their
supply circuits are protected with fuses.

Equipment
The loader unit consists of the lift frame with an integrated hydraulic
quickhitch for the attachments, lift and tilt cylinders and the corresponding
attachments.
The machine is equipped with a protective ROPS structure, and a
category I FOPS structure.
- ROPS is the abbreviation for “Roll Over Protective Structure”
- FOPS is the abbreviation for “Falling Object Protective Structure”

 Operation 5

Key-based immobilizer
The immobilizer is integrated in the ignition lock and can only be disabled
with the blue ignition keys!
Scope of delivery:
• Immobilizer installed in the machine
• 2 x blue keys (coded)
• 1 x red master key (for coding a blue key)

Coding new starting keys

New personal keys are coded with the master key (red). This is why it
must be carefully stored outside the machine.
The master key is only used for coding new keys, and cannot be used for
disabling the immobilizer.
Coding is performed by inserting the master key in the starter and by
turning it to position (1) for a maximum 5 seconds. After the master key
has been returned to position (0) and removed, you have 15 seconds for
inserting a key that requires coding.
It must be inserted in the starter and turned to position (1) in order to be
registered as a valid key.
• Coding is automatically stopped if no key requiring coding is detected
within 15 seconds.
• Several keys requiring coding can be inserted one after another in the
starter.
• Each key must remain at least 1 second in position (1).
• Coding can be performed for a maximum 10 keys.

Information
The immobilizer has only one master key!
► The immobilizer must be replaced by an authorized service center if
the master key is lost.

Enabling (locking) the immobilizer

1. Apply the parking brake.
2. Stop the engine.
3. Put the starting key (blue) in position 0.
➥ The immobilizer is enabled after 5 seconds.

BA WL34 * 09/2016 * 2070LP01T4_5-13_Optionen_en.fm * [en] 5-63

5 Operation

Disabling (releasing) the immobilizer

• It is disabled once the starting key (blue) is in the starter and has been
turned to position 1.
• Start the engine.
➥ The immobilizer is disabled as long as the engine runs.
Deleting coded keys
Deleting coded keys is necessary whenever a coded key is lost:
• All coded keys are deleted during deletion.
• After deletion has been performed, all existing keys can be recoded.
• Deletion is performed by inserting the master key in the starter and by
turning it to position (1) for a minimum 20 seconds.
• All coded keys are then deleted, and all existing keys can be recoded.
• The master key code is not deleted during deletion.

Safety functions
• The immobilizer remains enabled for 15 minutes and does not accept
any valid keys if more than 5 keys with different invalid codes are
inserted and turned in the starter within 1 minute.
• This function avoids ‘finding’ the correct key by chance by trying
different keys.
• Valid keys are accepted only after 15 minutes and after the position (0)
of the starter has been detected. This avoids testing keys without
actuating the mechanical starter, for example by moving the starter to
position (1) by force.
• Interruptions of the supply line or other control lines do not disable the
immobilizer or delete data (for example data codes).
All important data is saved in a non-volatile memory.

Information on residual pressure in the hydraulic system

• A fine jet of hydraulic oil under high pressure can penetrate through the
skin. Seek medical attention immediately if oil penetrates the skin or
eyes.
• Only open hydraulic systems after the pressure in them has been
released.
• Even if the machine is parked on level ground with its loader unit fully
lowered and its engine stopped, there can still be considerable residual
pressure in parts of the hydraulic system.
• Residual pressure is only slow to ease.
➥ If the hydraulic system is opened immediately after shutting down
the machine, release the pressure in the hydraulic system first.
• On machines equipped with load holding control valves on the lift and/
or tilt cylinder, open the valves in order to lower the loader unit, see
chapter Releasing residual pressure in the hydraulic system on

➥ Search for leaks using cardboard or paper on which the escaping
oil can been seen.
• Do not repair damaged pipe lines and hydraulic hoses, but replace
them immediately by new ones.

Information on engine exhaust

• Engine exhaust is hazardous to your health.
➥ Do not breathe in engine exhaust.
• If maintenance and inspection work has to be performed in enclosed
spaces with a running engine, extract the exhaust gases with an
extraction system and ensure that the space is well ventilated.

7 Maintenance

Information on batteries
• Batteries give off explosive gases.
➥ Avoid smoking, fire or open flames near batteries.
• Do not place any tools on batteries. Short-circuiting the terminals
produces sparks that ignite escaping battery acid gases.
• Battery acid is caustic. Avoid contact with the skin, eyes, mouth and
clothing.
➥ Wear protective equipment.
➥ In case of contact, immediately rinse the contaminated part of the
body with plenty of water and seek medical attention.
• Always take off metal jewelry and watches before performing work on
the battery or the electrical system.
• Dispose of old batteries in an environmentally friendly manner and
separately from other waste.

Information on the electrical system

• Always follow the correct sequence when disconnecting the battery.
➥ To disconnect: First the negative terminal, and then the positive
terminal.
➥ To connect: First the positive terminal, and then the negative
terminal.
• Always disconnect the battery before performing work on the electrical
system in which tools, spare parts, etc. can touch electrical compo-
nents or contacts.
• Always disconnect the battery before performing welding work.

After maintenance
• Once maintenance and inspection work is over, install all protections
again correctly.

7.21 Exhaust gas treatment

Information on exhaust-gas treatment
The engine exhaust system is equipped with a diesel particulate filter.

WARNING
The exhaust system becomes very hot, there is a burn hazard!
Can cause serious burns. Exhaust-gas temperatures at the exhaust
system can reach about 600°C (1,112°F) during regeneration, even if the
engine is running at idling speed.
► Keep your hands clear of the exhaust outlet.
► Keep a safe distance from the exhaust system.
► Do not open the engine cover if the exhaust system is hot.

NOTICE
The exhaust system becomes very hot, there is a fire hazard.
Hot exhaust gases in environments with easily flammable material can
cause fires and considerable damage to property.
► During regeneration of the diesel particulate filter, ensure that there is
no easily flammable material (for example, paper, dry grass, straw,
wood, wood ceilings, oil, fuel, etc.) in the immediate vicinity of the
exhaust system.
► Do not stop the machine with the engine running in the immediate
vicinity of easily flammable and combustible material, for example,
grass or straw.
► Do not use corrosion-protection agents for the exhaust system. They
can catch fire if the exhaust system is hot.
► In environments with easily flammable material, suppress the
"automatic regeneration."
► In environments with easily flammable material, do not activate
"Manual regeneration."

Information
Maintenance and repair on the diesel particulate filter may only be
performed by an authorized service center.
The diesel particulate filter is a wear part and has to be checked/cleaned
or replaced by an authorized service center every 3,000 operating hours.

Regeneration of diesel particulate filter

Description
The soot resulting from the combustion of the diesel fuel is collected and
DPF burned in the diesel particulate filter DPF at regular intervals. The exhaust
gas reaches a temperature of up to 600°C (1,112°F) at the exhaust outlet
during this process. This process is called regeneration.
The soot load is the contamination level in the diesel particulate filter.
Among other things, this contamination level depends on the load on the
diesel engine:
- High engine load = less deposits.
- Low engine load = more deposits.

Fig. 163 NOTICE

Damage to the diesel particulate filter!
If the soot load of the diesel particulate filter reaches a critical value, the
diesel particulate filter/engine can be damaged.
Engine output is reduced if the soot load reaches a critical value.
► If engine output is reduced, immediately start manual regeneration in a
safe environment – see “Manual regeneration” on page 7-59.
► Wait until manual regeneration is finished.
A running regeneration stops if the engine runs at idling speed and electric
consumers are switched on.
► During regeneration at idling speed, switch off all electric consumers
on the machine.

Indicator lights
Indicator lights indicate the operating states of the regeneration:
22
! 29 (illuminates): high exhaust gas temperature.
• This indicator light illuminates during regeneration. The indicator light
goes out once regeneration is over and the exhaust system has cooled
23 down.
! 27 (illuminates): Regeneration of the diesel particulate filter necessary.
• The indicator light illuminates if regenerating the diesel particulate filter
is necessary.
27
- Regeneration can be started manually.
- Regeneration is automatically started.
27 (illuminates) and 22 (flashes): maximum loading of the diesel
28 particulate filter reached.
• The loading of the diesel particulate filter is between 100% and 140%.
The engine output is reduced. Regeneration of the diesel particulate
filter necessary.
29 - Regeneration can be started manually.
- Regeneration is automatically started.
27 (illuminates), 22 (flashes) and 23 (illuminates): max. load of the diesel
Fig. 164 particulate filter exceeded.
• The loading of the diesel particulate filter is too high. Engine shuts
down every 30 seconds.
- A regeneration or repair can only be performed by the service
department.
28 (illuminates): Regeneration of the diesel particulate filter interrupted.
• The indicator light illuminates if regeneration has been interrupted.
- Regeneration can be started manually.

Operating states of the regeneration

• If the engine is operated with sufficient load, passive regeneration
occurs during operation. This regeneration has no effect on the perfor-
mance of the vehicle.
• If the load of the engine is insufficient, the diesel particulate filter
collects soot. A regeneration automatically starts upon reaching a
certain soot load and operationally warm engine. The indicator light 29
indicates that a regeneration is occurring.
• If the automatic regeneration is interrupted too often, the soot load in
the diesel particulate filter continues to rise. The indicator light 29
indicates that a regeneration is necessary.
• If this regeneration is also interrupted, the soot load rises to a level
where the engine output is reduced to a maximum of 1,800 rpm or the
maximum torque is reduced by 50%. In addition, the indicator light
flashes 22. The engine light flashing signals that it is the last chance for
the regeneration.
• If this regeneration is also interrupted, the indicator light 29, indicator
light 22 and indicator light 23illuminate. The engine shuts down every
30 seconds. A regeneration or repair can only be performed by the
service department.

Automatic regeneration
The "Automatic regeneration" mode is preset when the engine is started.
Diesel particulate filter regeneration is only started when the engine is at
23
operating temperature.
22 27 If the diesel particulate filter reaches a certain soot load, indicator an
automatic regeneration is triggered. The indicator light illuminates during
28 the regeneration 29.
The machine can be operated without any restriction during automatic
regeneration as long as there is no easily flammable material in the direct
vicinity of the machine. If automatic regeneration starts while the machine
is in the direct vicinity of easily flammable material, interrupt regeneration
manually 49 with the toggle switch – see “Interrupting automatic
29 regeneration manually” on page 7-58.
Regeneration stops if it is interrupted manually, or if the ignition switch key
is moved to position 0 during regeneration. This has the effect that the
soot particles are not removed from the diesel particulate filter. The
II following regeneration then takes longer.

0
NOTICE
Repeatedly interrupting regeneration can cause damage to the diesel
I particulate filter/engine.
► Once regeneration has started, finish it without any interruption, if
possible.
49 ► Interrupt regeneration manually only in exceptional cases, for example,
Fig. 165
if the machine is in the direct vicinity of easily flammable material.
► Once it has started, do not interrupt regeneration more than once.

Regeneration takes about 30 minutes. If is regeneration started, the

engine must run until regeneration is over, even if work with the machine
is finished before.

Information
Switch off all electric consumers on the vehicle, for example, the rotating
beacon, lighting, radio, etc. if regeneration is performed at idling speed.

➥ If the indicator light goes out 29, the regeneration is complete and
the exhaust system is cooled to operating temperature.

Interrupting automatic regeneration manually

If automatic regeneration starts while the machine is in the direct vicinity of
easily flammable material, interrupt regeneration manually with the toggle
23
switch49.
22 27 Switch 49 is located in Switch panel 2. This switch has three positions:
• Position 0 = OFF.
28 • Position I = interrupts regeneration of the diesel particulate filter.
• Position II = triggers a manual regeneration of the diesel particulate
filter.
Interrupt regeneration:
• Press and hold switch 49 at least 3 seconds in position I.
29 ➥ Automatic regeneration is interrupted.
- Indicator light 28 illuminates.
- Indicator light 29 goes out.
If automatic regeneration has been interrupted manually, then there are
II
the following possibilities:
• Manual regeneration can be triggered – see “Interrupting automatic
0 regeneration manually” on page 7-58.
• After restarting the engine, automatic regeneration starts again as
I soon as the engine reaches its operating temperature.
Regeneration stops if it is interrupted manually, or if the ignition switch key
is moved to position 0 during regeneration. This has the effect that the
soot particles are not removed from the diesel particulate filter. The
49 following regeneration then takes longer.

NOTICE
Repeatedly interrupting regeneration can cause damage to the diesel
particulate filter/engine.
► Once regeneration has started, finish it without any interruption, if

 Maintenance 7

Reduced engine output

The load in the diesel particulate filter increases due to multiple
interruptions of the regeneration. From a load of more than 100 %, the
engine automatically lowers the engine output. A maximum of 1,800 rpm
or a maximum torque of 50% is available.
In the display, the indicator light also illuminates 27 and the indicator
light 22 flashes.
If this regeneration is interrupted again, the engine independently
switches off every 30 seconds. The diesel particulate filter must be
replaced by the service department.

Manual regeneration
If automatic regeneration was interrupted manually, it starts again after
restarting the engine as soon as the engine reaches its operating
23
temperature.
22 27 However, regeneration can also be started manually as soon as the
machine is no longer in the direct vicinity of easily flammable material.
28 This is appropriate if it helps to avoid interrupting automatic regeneration
repeatedly, for example, if the machine is in regular operation in the direct
vicinity of easily flammable material.
Previous conditions for manual regeneration:
• The engine must be at its operating temperature.
29 • Indicator light 27 must illuminate.
Activate regeneration manually:
1. Drive the machine into a safe area with no easily flammable material.
2. Press and hold switch 49 in position II for about 15–20 seconds until
II indicator light 27 illuminates.
➥ The indicator light illuminates during the regeneration 29.
0 The machine can be operated without any restriction during manual
regeneration as long as there is no easily flammable material in the direct
vicinity of the machine.
I
For regeneration during idling:
• Apply the parking brake.
• Lower the loader unit to the ground.
49
• Shut off all electric consumers on the vehicle, e.g. rotating beacon,
Fig. 167 lighting, radio, etc.
Regeneration takes about 30 minutes. This means that if regeneration is
started, the engine must run until regeneration is over, even if work with
the machine is finished before.
The indicator light 29 goes out once regeneration is over and the exhaust
system has cooled down.

9.10 Coolant
Information on coolants
Check the coolant level regularly. The coolant must cover the radiator fins.
Ensure that enough antifreeze is always added to the coolant, even in
summer. The antifreeze also prevents internal corrosion of the radiator
and the engine.

A word to the user/operator

It is YOUR responsibility to read and understand the safety manual and the manufacturer’s manual(s) before
operating this machine. This safety manual takes you step-by-step through your working day.
In reading this manual, you will note that any illustration depicting an unsafe work procedure or situation is
labeled both with the words “wrong” and the mark of an “X” on the illustration. Each illustration is also num-
bered and the same number appears in the text in parenthesis. This number is placed at the end of the writ-
ten text that refers to the illustration. While some of the illustrations appearing in this manual are in the
nature of “cartoons”, this approach is intended solely as a means to promote your attention to the text. As
noted repeatedly throughout this manual, AEM and its Earthmoving Equipment Council are very serious
about risks to human life and health caused by unsafe practices.
Remember that YOU are the key to safety. Good safety practices not only protect you but also protect the
people around you. Study this manual and the manufacturer’s manual(s) for your specific machine. Make
them a working part of your safety program. Keep in mind that this safety manual is written for only this type
of machine. Practice all other usual and customary safe working precautions, and above all—

REMEMBER — SAFETY IS UP TO

Be Careful With Fluids Under Pressure

The hydraulic system may be under pressure whenever the
engine is running and may hold pressure even after
shutdown.

Install cylinder rod support struts or block the cylinders and

equipment securely before working on the hydraulic system.

Cycle all hydraulic steering and other controls after shutdown.

When venting or filling the hydraulic system, loosen the filler
cap slowly and remove it gradually. If the system is equipped
with an accumulator, see the manufacturer’s service manual
for discharge and recharge instructions.
Do not permit an open flame around the hydraulic system.

Clean up spilled fluid immediately.

which will damage eyes or skin on contact. Always
wear a face shield to avoid acid in eyes. If acid
contacts eyes, flush immediately with clean water and
get medical attention. Wear rubber gloves and
protective clothing to keep acid off skin. If acid
contacts skin, wash off immediately with clean water,
then seek medical attention.
WARNING: Lead-acid batteries produce flammable
and explosive gases. Keep arcs, sparks, flames and
lighted tobacco away. (55)

Use a flashlight to check battery electrolyte level. Always

check with engine stopped. (56)
Do not charge a battery or jump-start the engine if the battery

explosive decompression.
Keep wheel lug nuts tightened to manufacturer’s
recommendations.
A rise in tire pressure is normal during operation. It should
NOT be reduced. High speeds during transport may
produce excessive tire pressures due to heat. REDUCE
YOUR SPEED or stop and let tires cool.
When adjusting tire pressure, do so from a distance. Use a
long hose with self-attaching chuck. Always stand behind
tread when adjusting tire pressure. (58)
