Fuel, Oil and Hydraulic Fluid Fire Hazards
Fuel, oil and antifreeze will catch fire if it is brought close to a
flame. Fuel is particularly flammable and can be hazardous.
Always strictly observe the following.
Add fuel, oil, antifreeze and hydraulic fluid to the machine only in
a well ventilated area. The machine must be parked with
controls, lights and switches turned "OFF". The engine must be
"OFF" and any flames, glowing embers, auxiliary heating units
or spark causing equipment must be doused, turned "OFF" and/
or kept well clear of the machine.
Static electricity can produce dangerous sparks at the fuel filling
nozzle. In very cold, dry weather or other conditions that could
produce a static discharge, keep the tip of the fuel nozzle in
constant contact with the neck of the fuel filling nozzle, to
provide a ground.
Keep fuel and other fluid reservoir caps tight and do not start the
engine until caps have been secured.
Precautions When Handling Fluids at High
Temperature
Immediately after operations are stopped, the coolant, engine
oil, and hydraulic oil are at high temperature and the radiator
and hydraulic tank are still under pressure. Attempting to
remove the cap, drain the oil or coolant, or replace the filters
may lead to serious burns. Always wait for the temperature to go
down, and follow the specified procedures when carrying out
these operations.
To prevent hot coolant from spurting out, shut down engine, wait
for the coolant to cool, then loosen the cap slowly to relieve the
pressure.
To prevent hot oil from spurting out, shut down engine, wait for
the oil to cool, then loosen the cap slowly to relieve the pressure.
