1.2 Safety Precautions
(Observe these instructions for your own safety!)
Precautions for Operation
Filler Cap of Coolant Tank
Never open the cap of the coolant tank while the engine is still hot.
Steam and hot water may spurt out and burn you seriously. Wait until
the temperature of the coolant tank has dropped, wrap a cloth around
the filler cap, loosen the cap very carefully and slowly to remove the
system pressure before removing the cap. After inspection, refasten the
cap firmly.
Battery
Never smoke or permit sparks near the battery, because it may emit ex-
plosive hydrogen gas. Place the battery in a well-ventilated place.
Fuel
Use only diesel fuel. Never use other fuels, including gasoline, kero-
sene, etc., because they could cause a fire. The wrong fuel could also
cause the fuel injection pump and injector to fail due to lack of proper
lubrication. Be sure to check that you have selected the correct diesel
fuel before filling the fuel tank.
Do not use starting fluids or sprays. Their use may cause explosion, se-
rious injury and engine damage.
Fire Prevention
Be sure to stop the engine and confirm that there are no open flames in
the vicinity before fueling. If you do spill fuel, wipe such spillage careful-
ly and dispose of the wiping materials properly. Wash your hands thor-
oughly with soap and water.
Never place oil or other flammable material in the engine room.
Install a fire extinguisher near the engine room, and familiarize yourself
with its use.
Exhaust Gas
Exhaust gas contains poisonous carbon monoxide and should not be
inhaled.
Be sure to install ventilation ports or ventilators in the engine room and
ensure good ventilation during engine operation.
