Personal injury can result from contact with refrigerant. This system is under pressure at all times, engine running or not. 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 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. 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 either away from the machine or where they can be seen. |

- Turn the On/Off switch of the air conditioner to the OFF position.
- Make sure that the circuit pressure is balanced after the air conditioning system has been turned OFF.
- Hold part (A) of quick coupler (13) and slide part (B) of sleeve (12) upward. This will release the hose from charge valve (11) .
- Remove the high pressure hose in the same manner.
Note: After the manifold gauge set is removed, it is necessary to cap the charging valves.
