Note: Protect the cooling system by adding premixed 50% water and 50% ethy-
lene glycol to the system. This mixture will protect the cooling system to -34°F
(-36°C).
5. Fill the radiator fully and the recovery
tank half full with the premixed
coolant.
6. Reinstall the radiator cap.
7. Run the engine until it is at operating
temperature. Stop the engine and let it
cool. Check the coolant level. Add
more coolant if required.
Chaincases
The chaincase contains the drive
sprockets and drive chains. There are two
plugs in each chaincase. One is to drain
the fluid and the other is to check the fluid
level. Refer to the
Maintenance Schedule
chapter (page 67) for change intervals.
Refer to the
Lubrication topic (page 44)
for information on oil type and quantity.
Checking and Adding Oil
1. Park the loader on a level surface.
Stop the engine.
2. Remove the check plug from each
chaincase housing. If the oil can be reached with the tip of your finger, the oil
level is adequate.
3. If the level is low, add fluid through the check plug until the oil level reaches
the edge of the hole. Reinstall the check plug.
Draining Oil
1. Raise the rear of the machine to aid in draining the chaincases.
2. Remove the drain plug on each chaincase and drain the oil into a suitable
container.
3. Reinstall and tighten the drain plugs.
4. Refill the chaincases at the check plugs.
Seat and Restraint Bar Switches
Electrical switches in the seat and restraint bar must be closed (operator sitting in
the seat and restraint bar lowered) to complete the circuit and start the engine.
