5. Oil Cooler and Cooling Fan
Oil returning from the control valve is circulated through
the oil cooler before being sent to other parts of the
hydraulic system.
An engine cooling fan drives air through the oil cooler
when the rear door is closed. Refer to Figure 4.7E.
The oil cooler should be checked daily for dirt buildup on
the cooling fins. If the air flow is restricted through the
cooling fins, overheating of the hydraulic system may
occur. Clean any dirt buildup with compressed air. Flush
with water if necessary. Figure 4.7E shows the radiator/oil
cooler setup for the loader.
6. Brake Service Override
A service override has been incorporated for use by
Thomas Dealers. The normal position of the plunger is
down and turned into the locked position (Fig. 4.7F).
To release the park brake, turn the release button counter
clockwise. Go to the rear of the machine and pressurize the
small quick coupler to 200 psi to release the park brake
(Fig. 4.7G).
