• Wear protective glasses and
protective shoes when working.
• DO NOT wear loose-fitting or torn
clothing. Tie back and/or tuck in long
hair. Remove all jewelry when
working.
• Before beginning any repair,
disconnect the battery (negative [-]
cable) and discharge any capacitors.
• Put a “DO NOT OPERATE” tag in the
operator's compartment or on the
controls.
• Allow the engine to cool before
slowly loosening the coolant filler cap
to relieve the pressure from the
cooling system.
WARNING
Removing the fill cap on a hot engine
can cause scalding coolant to spray
out and burn you badly. If the engine
has been in operation within the previ-
ous 30 minutes, be very careful in re-
moving the fill cap. Protect face,
hands, and arms against escaping flu-
id and steam by covering the cap with
a large, thick rag. DO NOT try to re-
move it until the surge tank cools down
or if you see any steam or coolant es-
caping. In any situation, remove the
cap very slowly and carefully. Be ready
to back off if any steam or coolant be-
gins to escape.
• Always use wheel chocks or proper
jack stands to support the vehicle or
vehicle components before
performing any service work. DO
NOT work on anything that is
supported only by lifting jacks or a
hoist. Before resting a vehicle on jack
stands, be sure the stands are rated
for the load you will be placing on
them.
• Before removing or disconnecting
any lines, fittings, or related items,
relieve all pressure in the air, oil, fuel,
and cooling systems. Remain alert
for possible pressure when
disconnecting any device from a
system that contains pressure. High
pressure oil or fuel can cause death
or personal injury.
• Always wear protective clothing when
working on any refrigerant lines and
make sure that the workplace is well
ventilated. Inhalation of fumes can
cause death or personal injury. To
protect the environment, liquid
refrigerant systems must be properly
emptied and filled using equipment
that prevents the release of
refrigerant gas. Federal law requires
capturing and recycling refrigerant.
• When moving or lifting any heavy
equipment or parts, make sure to use
proper techniques and assistance.
Ensure all lifting devices such as
chains, hooks, or slings are in good
condition and are of the correct load
capacity. Make sure all lifting devices
are positioned correctly.
• Corrosion inhibitors and lubricating
oils may contain alkali. DO NOT get
the substance in eyes and avoid
prolonged or repeated contact with
skin. DO NOT swallow. If ingested,
seek immediate medical attention.
DO NOT induce vomiting. In case of
contact, immediately wash skin with
soap and water. In case of harmful
contact, immediately contact a
physician. Always keep any
chemicals OUT OF REACH OF
CHILDREN.
