General Precautions for Removing and Installing the Air
Conditioning System Components
Operator Cab: Service and Repairs
Do not let the refrigerant contact your skin or eyes as there is a
possibility of serious injury.
Always wear safety goggles or a face shield when you work with the
air conditioning system components.
Loosening any air conditioning system fitting or component allows
the pressurized refrigerant to escape, causing possible injury.
Do not loosen any system fitting or component until a certified air
conditioning service technician discharges the system completely.
In some conditions, the pressurized mixtures of the refrigerant and
air are combustible.
Do not use compressed air for leak test or pressure test of the air
conditioning system.
1. Before you service any air conditioning system components, park the
machine on a level surface, set the parking brake, lower the cutting deck or
attachments, and shut off the engine. Remove the key from the key switch.
2. Clean the machine before you disconnect, remove, or disassemble any air
conditioning system components. Clean the system to prevent the system
contamination while you perform the service procedures.
3. Before you loosen or remove any air conditioning system hoses or other
components, have a certified air conditioning service technician collect the
system refrigerant and then evacuate the air conditioning system completely.
It is illegal to open the refrigerant to the atmosphere.
4. Install caps or plugs on any lines, fittings, or components that are left open or
exposed to prevent moisture and contaminants from entering into the system.
5. Label all the disconnected system lines and hoses for proper installation
after repairs are completed.
6. If you remove the compressor from the machine, keep the compressor in
the same orientation as it was in the installed position. This prevents the
compressor oil from filling the compressor cylinders.
7. Note the position of the fittings (especially elbow fittings) before removal.
Note: Mark the parts, if necessary, and ensure that they are aligned correctly
when installing the hoses and tubes.
