Adding Fuel Or Oil

• Spilled fuel and oil may cause slipping. Always
clean up spills immediately.
• Always add fuel and oil in a well-ventilated area.
• When refueling, stop the engine and do not
smoke.
• Tighten the cap of the fuel and oil fillers securely.
• Never use fuel to wash parts.

Radiator Coolant Level

If it is necessary to add coolant to the radiator, stop
the engine and allow the engine and radiator to cool
down before adding the coolant. Depress the
pressure release button on the cap to vent cooling
system pressure. Slowly loosen the cap to relieve
any remaining pressure.

Use Of Lighting

When checking fuel, oil, coolant or battery electrolyte,
always use lighting with anti-explosion specifications.
If such lighting equipment is not used, there is danger
of an explosion.

Precautions With The Battery

When repairing the electrical system or performing
electrical welding, remove the negative (-) terminal of
the battery to stop the flow of current.

Handling High Pressure Hoses

• Do not bend high pressure hoses or hit them with
hard objects. Do not use any bent or cracked
piping, tubes or hoses. They may burst during
use.
• Always repair any loose or broken hoses. If fuel
or oil leaks, it may result in a fire.

Precautions With High Pressure Oil

• Work equipment circuits are always under
pressure. Do not add oil, drain oil or perform
maintenance or inspections before completely
releasing the internal pressure.
• Small, high-pressure pin hole leaks are extremely
dangerous. The jet of high-pressure oil can
pierce the skin and eyes. Always wear safety
glasses and thick gloves. Use a piece of
cardboard or a sheet of wood to check for oil
leakage.
• If you are hit by a jet of high-pressure oil, consult
a doctor immediately for medical attention.
Performing Maintenance Near High Temperature
Or High Pressure
Immediately after stopping operation, engine coolant
and operating oils are at high temperature and under
high pressure. If the cap is removed, the oil or water
is drained, or the filters are replaced under these
conditions, it may result in burns or other injury. Wait
for the temperature to cool and pressure to subside
before performing the inspection and/or maintenance
as outlined in the shop manual.
