Burn Prevention
Never jump across the starter solenoid terminals
in order to start the engine. Unexpected machine
movement could result.
Whenever there are equipment control linkages the
clearance in the linkage area will change with the
movement of the equipment or the machine. Stay
clear of areas that may have a sudden change in
clearance with machine movement or equipment
movement.
Stay clear of all rotating and moving parts.
If it is necessary to remove guards in order to perform
maintenance, always install the guards after the
maintenance is performed.
Keep objects away from moving fan blades. The fan
blade will throw objects or cut objects.
Do not use a kinked wire cable or a frayed wire cable.
Wear gloves when you handle wire cable.
When you strike a retainer pin with force, the retainer
pin can fly out. The loose retainer pin can injure
personnel. Make sure that the area is clear of people
when you strike a retainer pin. To avoid injury to
your eyes, wear protective glasses when you strike
a retainer pin.
Chips or other debris can fly off an object when you
strike the object. Make sure that no one can be
injured by flying debris before striking any object.

Do not touch any part of an operating engine.
Allow the engine to cool before any maintenance is
performed on the engine. Relieve all pressure in the
air system, in the oil system, in the lubrication system,
in the fuel 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 the coolant level only after the engine has
been stopped.
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 in
order 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 components can cause personal
injury. Do not allow hot oil to contact the skin. Also,
do not allow hot components to contact the skin.
Remove the hydraulic tank filler cap only after the
engine has been stopped. The filler cap must be
cool enough to touch with a bare hand. Follow the
standard procedure in this manual in order to remove
the hydraulic tank filler cap.
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.
