CYLINDER AS 1163580 - Caterpillar

Personal injury can result from contact with refrigerant.This system is under pressure at all times, even if the engine is not running. Heat should never be applied to a charged system.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 gauges indicate the system is empty of refrigerant.Always use caution when a fitting is removed. Slowly loosen the fitting. If the system is still under pressure, evacuate the system recovering the refrigerant before removing the fitting.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.Before any checks of the air conditioning and heating system are made, move the machine to a smooth horizontal surface. Lower all implements to the ground. Make sure the transmission is in neutral or park and that the parking brake is engaged. Keep all other personnel away from the machine or where they can be seen.
Personal injury can result from 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.
Never weld or solder any charged components.
Before any problem solving procedures are performed, read the manual for the heating and air conditioning system. Make a visual inspection of the complete air conditioning and heating system.During any service of the air conditioning system, all open connections are required to be capped or plugged with clean plastic part. Failure to cap open connections or failure to plug open connections will allow moisture into the system and lead to further damage.When you are preparing to work on the air conditioning system, it is important to prepare the machine properly by performing a lockout/tagout procedure on the machine and on the air conditioning system. All charging and leak testing must be done in a ventilated area.Lockout/Tagout Procedure
When possible, park the machine on a smooth, level surface.
Set the parking brake.
Lower and lock all hydraulic implements.
Turn the key start switch to the OFF position and remove the key.
Turn the battery disconnect switch to the OFF position.
