Safety Precautions
Always use protective glasses or goggles when car-
rying out work where there is a risk of splinters,
grinding sparks, acid splashes or where other
chemicals are used. The eyes are extremely sensi-
tive, an injury could result in blindness!
Avoid getting oil on the skin! Repeated exposure to oil
or exposure over a long period can result in the skin
becoming dry. Irritation, dryness and eczema and oth-
er skin problems can then occur. Used oil is more
dangerous than fresh oil from a health aspect. Use
protective gloves and avoid oil soaked clothes and
shop rags. Wash regularly, especially before eating.
There are special skin creams which counteract dry-
ing out of the skin and make it easier to clean off dirt
after work is completed.
Many chemicals used on the product (for example en-
gine and transmission oils, glycol, gasoline and diesel
oil), or chemicals used in the workshop (for example
degreasing agents, paint and solvents) are dangerous
to health. Read the instructions on the product pack-
aging with care! Always follow the safety precautions
for the product (for example use of protective mask,
glasses, gloves etc.). Make sure that other personnel
are not exposed to hazardous chemicals, for example
in the air. Ensure good ventilation in the work place.
Follow the instructions provided when disposing of
used or leftover chemicals.
Exercise extreme care when leak detecting on the fuel
system and testing the fuel injector nozzles. Use eye
protection. The jet from a fuel injector nozzle is under
extremely high pressure and has great penetrative en-
ergy, so the fuel can penetrate deep into the body tis-
sue and cause serious personal injury. Danger of
blood poisoning.
WARNING! The delivery pipes must under no circum-
stances be bent. Damaged pipes should be replaced.
All fuels and many chemical substances are flamma-
ble. Do not allow naked flame or sparks in the vicinity.
Fuel, certain thinner products and hydrogen from bat-
teries can be extremely flammable and explosive
when mixed with air. Smoking is not to be permitted in
the vicinity! Ensure that the work area is well ventilat-
ed and take the necessary safety precautions before
starting welding or grinding work. Always ensure that
there are fire extinguishers at hand when work is being
carried out.

Ensure that rags soaked in oil or fuel and used fuel
or oil filters are stored safely. Rags soaked in oil
can spontaneously ignite under certain circum-
stances. Used fuel and oil filters are environmental-
ly dangerous waste and must be deposited at an
approved site for destruction together with used lu-
bricating oil, contaminated fuel, paint remnants, sol-
vent, degreasing agents and waste from washing
parts.
Never expose a battery to naked flame or electrical
sparks. Never smoke in proximity to the batteries. The
batteries give off hydrogen gas during charging which
when mixed with air can form an explosive gas - oxy-
hydrogen. This gas is easily ignited and highly volatile.
Incorrect connection of the battery can cause a single
spark which is sufficient to cause an explosion with
resulting damage. Do not shift the connections when
attempting to start the engine (spark risk) and do not
lean over any of the batteries.
Always ensure that the Plus (positive) and Minus
(negative) battery cables are correctly installed on the
corresponding terminal posts on the batteries. Incor-
rect installation can result in serious damage to the
electrical equipment. Refer to the wiring diagrams.
Always use protective goggles when charging and
handling the batteries. Battery electrolyte contains sul-
furic acid which is highly corrosive. Should the battery
electrolyte come into contact with unprotected skin
wash off immediately using plenty of water and soap.
If battery acid comes in contact with the eyes, immedi-
ately flush with plenty of water and obtain medical as-
sistance at once.
Turn the engine off and turn off the power at the main
switch(es) before carrying out work on the electrical
system.
Clutch adjustments must be carried out with the en-
gine stopped.
Use the lifting eyes fitted on the engine when lifting the
drive unit. Always check that the lifting equipment
used is in good condition and has the load capacity to
lift the engine (engine weight including gearbox, if fit-
ted, and any extra equipment installed). Use an ad-
justable lifting beam or lifting beam specifically for the
engine to raise the engine to ensure safe handling and
to avoid damaging engine parts installed on the top of
the engine. All chains and cables should run parallel to
each other and as perpendicular as possible in rela-
tion to the top of the engine.
