At operation temperature, the engine coolant is hot and under pressure. Steam can cause personal injury. Check the coolant level only after the engine has been stopped and the fill cap is cool enough to touch with your bare hand. Remove the fill cap from the radiator slowly to relieve pressure. Cooling system conditioner contains alkali. Avoid contact with the skin and eyes to prevent personal injury.
Release the pressure in the cooling system by slowly loosening the filler cap on the radiator. Drain the coolant from the radiator and oil from the hydraulic oil cooler.
At operating temperature, the hydraulic oil tank is hot and under pressure. Hot oil can cause burns. To prevent possible personal injury, release the pressure in the hydraulic system before and hydraulic lines or components are disconnected or removed.
Release the pressure in the hydraulic system as follows: a. shut off the engine.b. Move the control levers through their full travel strokes. This will relieve any pressure that may be present in the pilot system.c. Slowly loosen the air breather cap on the hydraulic oil tank to release the pressure.d. Tighten the air breather cap on the hydraulic oil tank.e. The pressure in the hydraulic system has now been released. Lines and components can now be removed.
Always wear goggles when working on air conditioning systems. The system is under pressure at all times, engine running or not. Escaping refrigerant R-12 (C C12 F2 Dichloro Difluoro Methane) and refrigerant R-134A can cause freezing of human flesh. Do not smoke while working on air conditioning. Inhaling Refrigerant R-12 or R-134A through any smoking material, although not toxic or flammable, can cause violent illness. Also heat must never be applied to a charged system. See Air Conditioning And Heating Service Manual Form No. SENR3334-01 and SENR5664, for more information on removal and installation of lines and refrigerant from the system.
Release the refrigerant R-12 from the system. See Air Conditioning And Heating, Purging The System, Form No. SENR3334-01. 1. Disconnect wiring harness (4). Disconnect line (1), remove two nuts (2) and remove ether starting aid (3). 2.
