NOTICE
Keep all parts clean from contaminants.
Contamination of the hydraulic system with foreign material will
reduce the service life of the hydraulic system components.
To prevent contaminants from entering the hydraulic system, always
plug or cap the lines, fittings, or hoses as they are disconnected. Cover
any disassembled components and clean them properly before
assembly.
Clean the hydraulic system properly after any major component
exchange or especially after a component failure, to remove any
contamination.
Personal injury can result from hot coolant, steam and alkali.
At operating temperature, engine coolant is hot and under pressure.
The radiator and all lines to heaters or the engine contain hot coolant or
steam. Any contact can cause severe burns.
Remove cooling system pressure cap slowly to relieve pressure only
when engine is stopped and cooling system pressure cap is cool enough
to touch with your bare hand.
Do not attempt to tighten hose connections when the coolant is hot, the
hose can come off causing burns.
Cooling System Coolant Additive contains alkali. Avoid contact with
skin and eyes.
Note: Put identification marks on all lines, on all hoses, on all wires and on all tubes for
installation purposes. Plug all lines, all hoses and all tubes. This will help to prevent fluid loss and
this will help to keep contaminants from entering the system.
1. Release the pressure in the cooling system by slowly loosening the filler cap on the radiator.
2. Drain the coolant from the radiator. The capacity of the cooling system is 37 L (10 US gal).
3. Remove the lower access panel from the left side of the engine. Remove the lower access
panel from the right side of the engine.

7. Remove bolts (3) and remove fan guard assemblies (4) from the radiator assembly.
8. Loosen hose clamps (7) and remove tube assembly (8) from the machine.
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 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.
Use a certified recovery and recycling cart to properly remove the
refrigerant from the air conditioning system.
