General Safety Precautions
Proper service and repair is important to the safe, reliable
operation of all motor vehicles. Detailed service procedures are
recommended and described in various TEREX publications i.e.;
Maintenance Manuals
Operators Handbook
Parts Book
These publications offer effective methods for performing service
operations. Some of these service operations require the use of
tools specially designed for the purpose. The special tools should
be used when, and as recommended.
It is important to note that these publications contain various
WARNINGS and NOTES which should be carefully read in order to
minimise the risk of personal injury, or the possibility that improper
service methods will be followed which may damage the vehicle or
render it unsafe.
All trucks are installed with warning and instruction decals. These
decals also offer guidance towards the safe service, maintenance
and operation of the TEREX truck.

Safety When Servicing
Service and maintenance work not carried out
correctly can be dangerous to yourself and others.
Always attach a 'DO NOT OPERATE' or similar
warning sign to the ignition switch or a prominent
control before cleaning, lubricating or servicing the
vehicle.
Never allow anyone to work on the vehicle while it is
moving. Make sure there is no one on the vehicle
before working on it.
Do not work under or near an unblocked or
unsupported body. Always use the body safety pins.
Do not work under or near any unblocked or
unsupported linkage, part or vehicle.
Block wheels from rotating when working in and
around and under the truck.

Safety When Servicing
Always relieve stored pressure before servicing any
pressurised system. Follow the procedures and safety
precautions detailed in the relevant Maintenance Manual
section.
Be alert to high pressure fluid leaks. Stop Truck, Relieve
Stored Pressure and Fix Failure.
When changing oil in the engine, transmission and
hydraulic systems, or removing hydraulic lines,
remember that the oil may be hot and can cause
burns to unprotected skin.
When working on or around exhaust components,
remember that the components may be hot and can
cause burns to unprotected skin.

MAKING WELD REPAIRS
BEFORE WELDING ON TRUCK;
• TURN KEY-SWITCH OFF
• TURN MASTER SWITCH OFF
DISCONNECT;
• BATTERY SUPPLY & EARTH CABLES
• ALTERNATOR EARTH & SUPPLY CABLES
• TRANSMISSION ECU
• ENGINE ECM
• OPTIONS ie. REAR VIEW TV, LUBE SYSTEMS etc.

Jump Starting Precautions
Starting the Engine with Jumper Cables 8
WARNING
Hazardous hydrogen gas and sulphuric acid. Check for required voltage and
polarity connections to discharged batteries. Excessive booster voltage and/or
incorrect jumper cable connections, open flame, lighted cigar, or other
ignition source can cause battery explosion/fire. Keep all sources of ignition
away from batteries. Do not lean over batteries, and, wear eye protection at
all times to prevent personal injury.
Do not jump start a vehicle by using arc welding equipment.
Currents and voltages are dangerously high and cannot be sufficiently
reduced to make the method safe.
Note: Be sure machines are not touching each other. Use cables that are equal to cable size on
the machine. Booster battery should be the same specification as discharged battery.
If jumper cables are used to start an engine, be sure to follow this procedure:
Connect one end of a jumper cable, usually coloured red, to the discharged battery 'POSITIVE'
(+) post. Connect the other end of the same cable to the 'POSITIVE' (+) post on the booster or
charged battery.
Connect one end of the second cable, usually coloured black, to the 'NEGATIVE’ (-) post of the
booster battery. Connect the other end of the 'NEGATIVE' (-) cable to machine frame for
grounding so that if a spark occurs, it is away from battery fumes (explosive hydrogen).
Check for cause of failure on the dead battery.

Routine Service and Maintenance
Lubrication And Servicing 9
Lubrication is an essential part of preventive maintenance. It is important that the instructions
regarding types of lubricants and the frequency of their application be followed to prolong the
useful life of the machine. Periodic lubrication of moving parts reduces to a minimum the
possibility of mechanical failures.
Thoroughly clean all fittings, caps, plugs etc., to prevent dirt from entering the system while
servicing.
Lubricants must be at operating temperature when draining.
Do not operate any system unless oil level is within the operating range as indicated on oil
level dip stick, sight gauge or level plug.

Pre-Operational Checks
Pre-Operational Checks 10
• Before the engine is started ensure the machine is ready for operation.
• The machine should be in a level position to permit accurate checking of fluid
quantities in the engine and other components.
• Make sure parking brake is set and block wheels if necessary to prevent
accidental movement of the machine while checking component levels.
• Test all lights and horn for proper operation.
• Walk around the machine and carry out the Inspections and Component
Checks described in the drawing on the following pages.

All change and service periods are recommendations based on average operating conditions. Lubricants showing evidence of
excessive heat, oxidation or dirt should be changed more frequently to prevent these conditions. Lubricant change and service

Recommendations;
• Use SOS to monitor condition & maintenance
requirements of your equipment.
• SOS taken when oil is warm & particles suspended.
Ensuring sample is representative of oil
compartment.
• When using drain stream for SOS, do not collect
from initial or final draining.
