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.
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.
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. A 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.
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 when 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.
Waste materials
• Never dump oil into a sewer system, river, etc.
• Always put oil drained from your truck in
appropriate containers. Never drain oil directly
onto the ground.
• Obey appropriate laws and regulations when
disposing of harmful objects such as oil, fuel,
coolant, solvent, filters and batteries.
• The machine may be equipped with optional high
intensity discharge lamps which contain mercury.
These lamps must be reused, recycled or
properly disposed of in accordance with
applicable local, state and federal laws.
