WARN I N G
Hot oil and hot components can cause personal injury. DO NOT allow hot oil or hot components to con-
tact skin.
DO NOT service cooling system unless engine has been allowed to cool down. This is a pressurized cool-
ing system and escaping steam or hot coolant may result in serious burns.
DO NOT remove cooling system radiator cap when engine is hot. Allow engine to cool down. Loosen cap
to first stop and let any pressure out of cooling system, then remove cap. Failure to follow this warning
may result in serious burns.
Wear effective eye, hand, and skin protection when handling coolants. Failure to do so may result in
injury to personnel.
DO NOT disconnect or remove any hydraulic system line or fitting unless engine is shut down and
hydraulic system pressure has been relieved. Tighten all connections before applying pressure. Escaping
hydraulic fluid under pressure can penetrate the skin, causing injury to personnel.
At operating temperature, hydraulic oil is hot. Allow hydraulic oil to cool before disconnecting any
hydraulic lines. Failure to follow this warning may result in injury to personnel.
Personal injury can result from contact with refrigerant.
Contact with refrigerant can cause frost bite. Keep face and hands away to help prevent injury.
Protective goggles must always be worn when refrigerant lines are opened, even if the gages indicate the
system is out of refrigerant.
Always use precaution when a fitting is removed. Slowly loosen the fitting. If the system is still under
pressure, release it slowly in a well ventilated area.
Personal injury or death can result from inhaling refrigerant through a lit cigarette.
Inhaling air conditioner refrigerant gas through a lit cigarette or other smoking method or inhaling
fumes released from a flame contacting air conditioner refrigerant gas can cause bodily harm or death.
DO NOT smoke when servicing air conditioners or wherever refrigerant gas may be present.
Use a certified recovery and recycling cart to properly remove the refrigerant from the air conditioning
system.
C AU T I O N
Care must be taken to ensure that fluids are contained during performance of inspection, maintenance,
testing, adjusting, and repair of the component. Be prepared to collect the fluid with suitable containers
before opening any compartment or disassembling any component containing fluids.
Dispose of all fluids according to local regulations and mandates.
Wipe area clean around all hose connections to be opened during removal. Cap lines and hoses and plug
openings after removing. Contamination of cooling system could result in premature failure.
