Avoid getting oil on your skin! Repeated expo-
sure to oil or exposure over a long period can re-
sult in the skin becoming dry. Irritation, dryness
and eczema and other 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 rags. Wash regularly, es-
pecially before eating. There are special skin
creams which counteract drying out of the skin
and make it easier to clean off dirt after work is
completed.
Most chemicals intended for the product (e.g.
engine and transmission oils, glycol, petrol (gas-
oline) and diesel oil) or chemicals for workshop
use (e.g. degreasers, paints and solvents) are
hazardous. Read the instructions on the product
packaging 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 inadvertently
exposed to hazardous chemicals, for example in
the air. Ensure good ventilation in the work
place. Follow the instructions provided when dis-
posing of used or leftover chemicals.
Exercise extreme care when leak detecting on
the fuel system and testing the fuel injector noz-
zles. Use eye protection. The jet from a fuel
nozzle has very high pressure and great pene-
tration power. Fuel can force its way deep into
body tissue and cause severe injury. Danger of
blood poisoning (septicemia).
All fuels, and many chemicals, are flammable.
Do not allow naked flame or sparks in the vicini-
ty. Petrol (gasoline), some thinners and hydro-
gen gas from batteries are extremely flammable
and explosive when mixed with air in the correct
ratio. No Smoking! Ensure that the work area is
well ventilated and take the necessary safety
precautions before starting welding or grinding
work. Always ensure that there are fire extin-
guishers at hand when work is being carried out.
Make sure that oil and fuel soaked rags, and
used fuel and oil filters are stored in a safe
place. Rags soaked in oil can spontaneously ig-
nite under certain circumstances. Used fuel and
oil filters are polluting waste and must be hand-
ed to an approved waste management facility
for destruction, together with used lubrication oil,
contaminated fuel, paint residue, solvents, de-
greasers and wash residue.
Never expose a battery to naked flame
or electrical sparks. Never smoke close to the
batteries. The batteries generate hydrogen gas
when charged, which forms an explosive gas
when mixed with air. This gas is easily ignited
and highly volatile. A spark, which can be
caused by incorrect battery connection, can
cause a single spark which is sufficient to
cause an explosion with resulting damage. Do
not move the connections when you attempt to
start the engine (risk of arcing), and do not
stand and lean over one of the batteries.
Always ensure that the Plus (positive) and Mi-
nus (negative) battery cables are correctly in-
stalled on the corresponding terminal posts on
the batteries. Incorrect installation can result in
serious damage to the electrical equipment. Re-
fer to the wiring diagram.
Always use protective goggles when charging
and handling the batteries. Battery electrolyte
contains sulfuric acid which is highly corrosive.
Should the battery electrolyte come into contact
with unprotected skin wash off immediately us-
ing plenty of water and soap. If you get battery
acid in your eyes, flush at once with a generous
amount of water, and get medical assistance 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
engine stopped.
The existing lugs on the engine/reversing gear
should be used for lifting the assembly.
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 fitted, and any extra equipment).
Use an adjustable lifting beam or lifting beam
specifically for the engine to raise the engine to
ensure safe handling and to avoid damaging en-
gine 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.
If other equipment connected to the engine has
altered its center of gravity, special lifting devis-
es may be needed to obtain the correct balance
and safe handling.
Never carry out work on an engine suspended
on a hoist.
