Dynapac LP 852 is a vibratory padfoot roller that is designed to cope with many different types of
compaction work. The roller is designed essentially for compaction tasks in pipe trenches, around
the foundations of buildings, backfilling against supporting walls, and also for road construction.
The machine is equally suitable for work in confined spaces as for major compaction jobs.

Like all other machines that are powered by combustion engines, the plate is designed for
operation in well-ventilated areas.

We reserve the right to change specifications without notice.

WARNING SYMBOLS

WARNING Indicates danger or hazardous

procedure that could result in serious or fatal
personal injury if the warning is ignored.

CAUTION Indicates danger or hazardous proce-

dure that could result in damage to machine or
property if the warning is ignored.

Safety instructions CALIFORNIA

The safety instructions are included in this Proposition 65 Warning

manual and must be studied by the operator.
Always follow the safety rules and keep the Diesel engine exhaust and some of its
manual available for future use. constituents are known to the State of
California to cause cancer, birth
defects, and other reproductive harm.
Read through the entire manual before
starting any maintenance operations.

Ensure good ventilation (air extraction) if the

engine is run indoors.

2 LP 852 ILP852EN3
 GENERAL
It is important that the machine is maintained correctly to
ensure proper function. It should be kept clean so that any
leakage, loose bolts and loose connections can be discov-
ered in time.

Make a habit of inspecting the machine every day before

starting up by checking all round it to detect any sign of
leakage or other faults.

SPARE A THOUGHT FOR THE ENVIRONMENT!

Do not let oil, fuel and other environmentally haz-
ardous substances contaminate the environment.
Always dispose of used filters, drained oil and any
remaining fuel properly.

This manual contains instructions for periodic attention

which should normally be carried out by the operator.

There are additional instructions relating to the

engine, for which the manufacturer’s instructions
are detailed in the engine manual.

 SAFETY INSTRUCTIONS (FOR ALL LIGHT PRODUCTS)

Working with the hydraulic system

Regular maintenance of the hydraulic system is
important. Minor damage or a split hose or cou-
pling can have devastating consequences. Bear
in mind that the hydraulic hoses are made of
rubber and can deteriorate with age, which can
result in splitting. In all cases of uncertainty with
regard to durability or wear, replace the hoses
with new original hoses from Dynapac.

Working with battery

The battery contains poisonous and corrosive
sulphuric acid. Wear protective glasses and
avoid getting acid on your skin, clothes or on the
machines. If you get sulphuric acid on yourself,
rinse the skin with water. If you get acid in your
eyes, rinse them with water for at least 15 min-
utes and seek immediate medical treatment. The
gas that is emitted by the battery is explosive.
When fitting or replacing a battery, always take
care so that you do not short- circuit the battery
poles.

Repair
Never use a machine that is damaged. Qualified
repair work requires trained personnel, please
contact your nearest authorized workshop.

Extinguishing fires
If there is a fire in or on the machine, it is best
to use an ABE-class fire extinguisher. How-
ever, a BE-class CO2 extinguisher is also
suitable.

6 LP 852 ILP852EN3
 SAFETY WHEN DRIVING

Driving near an edge

When driving near an edge, at least two thirds of the
plate must be on firm solid ground.

If the machine tips over, switch off the

engine before attempting to lift the ma-
chine.

Slopes
Make sure that the work site is safe. Wet and loose
earth reduces manoeuvrability especially on sloping
ground. Always observe particular caution on sloping
and uneven terrain.

Where possible, avoid all driving across a

slope. Instead, drive up and down on slop-
ing ground.

Never work on slopes that are greater than the capabil-

Max 20° ity of the machine. Maximum slope of the machine in
or 36% operation is 20° (depending on condition of the ground).

Stopping the engine, manual controls.

1. Stop the machine and turn off vibrations (5).

2. Press down throttle control (7) and let engine idle a couple of minutes.
3. Turn the key (10) to zero to switch off the engine.
4. Press in parking brake (16) during transportation and parking.

Operating, manual controls.

Warning! Be sure that your working area is safe. Wet and loose soils reduce the
traction abilities of the machine, especially on grades. Always travel slowly on a
grade and over rough terrain.
Never drive up or down inclinations which exceed the gradability of the machine.
- Don't leave the machine with the engine running.
- Don't allow any passenger on the machine.

Travel

1. Note!! Always release the parking brake (16) before moving the machine.
2. Check back-up safety bar (14). When bar is depressed the machine stops immediately.
Be sure that the bar is always functioning properly.
3. Set the throttle control (7) to full speed. (Note! Operating speed.)
4. Select Speed Switch (4) position. “High” speed is used for moving the machine, but only
when driving forward. "Low" speed is used for compaction. When driving up on a slope the
LP roller change itself to low speed.
5. Regulate travel speed using the control levers (1, 2). For forward and reverse travel, move
both levers simultaneously. The left lever controls the drums on the left side of the machine
and the right lever controls the drums on the right side of the machine.
6. To steer in right direction, use left lever applying traction to drums on the
left side and turning the machine to the right. Use the right lever to steer to the left.
To turn on the spot move one lever forward and the other lever in reverse, drums
will counter-rotate. On soft material the drums dig into the ground.

Vibration

Caution! Never use vibration on hard surfaces such as frozen ground or concrete.
Use vibration only when machine is moving.

The Vibration Switch (5) functions only when the Speed Switch (4) is set to "Low",
it will not operate in "High".
The switch has 3 positions; ON Forward, OFF, and ON Reverse. This allows the
operator to select the direction of rotation of the eccentric shaft to improve traction.
Under normal operating conditions the switch may be set to vibrate in forward,
if traction is satisfactory when reversing there is no need to change. When traction
conditions get more difficult the switch may be set to ON Reverse, the counter clockwise
motion of the eccentric shaft assists traction.
