After the engine has stopped, you must wait for 60
seconds to allow the fuel pressure to be purged from
the high-pressure fuel lines before any service or
repair is performed on the engine fuel lines.
Allow the pressure to be purged in the air system, in
the hydraulic system, in the lubrication system, or in
the cooling system before any lines, fittings, or
related items are disconnected.
Coolant
When the engine is at operating temperature, the
engine coolant is hot. The coolant is also under
pressure. The radiator and all lines to the heaters or
to the engine contain hot coolant.
Any contact with hot coolant or with steam can cause
severe burns. Allow cooling system components to
cool before the cooling system is drained.
Check that the coolant level after the engine has
stopped and the engine has been allowed to cool.
Ensure that the filler cap is cool before removing the
filler cap. The filler cap must be cool enough to touch
with a bare hand. Remove the filler cap slowly to
relieve pressure.
Cooling system conditioner contains alkali. Alkali can
cause personal injury. Do not allow alkali to contact
the skin, the eyes, or the mouth.
Oils
Hot oil and hot lubricating components can cause
personal injury. Do not allow hot oil to contact the
skin. Also, do not allow hot components to contact
the skin.
Diesel Fuel
Diesel may be irritating to the eyes, respiratory
system, and skin. Prolonged exposure to diesel may
cause various skin conditions. Appropriate personal
protective equipment should be used. Refer to
supplier Material safety Data sheets for detailed
information.
Viton Seals
If Viton is burned, a product of this burnt material
is an acid which is hazardous. Do not allow burnt
material to come into contact with the skin or with
the eyes. Use the appropriate set of Personal Pro-
tective Equipment to protect your skin and eyes.
Failure to follow the instructions or heed the
warning could result in serious injury or death.
If there is need to come into contact with components
which have been burnt, ensure that the precautions
which follow are used:
• Ensure that the components have cooled.
• Use Neoprene gloves and discard the gloves
safely after use.
• Wash the area with calcium hydroxide solution
and then with clean water.
• Disposal of components and gloves which are
contaminated must be in accordance with local
regulations.
If there is contamination of the skin or eyes, wash the
affected area with a continuous supply of clean water
or with calcium hydroxide solution. Wash the area
effected for 15 to 60 minutes and obtain immediate
medical attention.
Batteries
Electrolyte is an acid. Electrolyte can cause personal
injury. Do not allow electrolyte to contact the skin or
the eyes. Always wear protective glasses for
servicing batteries. Wash hands after touching the
batteries and connectors. Use of gloves is
recommended.

All fuels, most lubricants, and some coolant mixtures
are flammable.
Flammable fluids that are leaking or spilled onto hot
surfaces or onto electrical components can cause a
fire. Fire may cause personal injury and property
damage.
After the emergency stop button is operated, ensure
that you allow 15 minutes, before the engine covers
are removed.
