HYDRAULIC SYSTEM
(Machines Before PJ.N. 9141518)
The equipment and steering hydraulic system is air pressurized. Before
servicing the system reservoir, the air supply must be shut off and the tank
depressurized.
Oil Level
Check the reservoir oil level after every 50 hours or weekly. If possible,
have oil at operating temperature, 120°F (44°C) or higher.
Shut off engine. Lower bucket to ground. Close air shutoff valve above
tank. Let pressurized air escape by very slowly removing the dipstick-filler cap.
Add oil as required.
If the oil level is to be checked after servicing parts in the system, run the
loader arm, bucket and steering wheel through several complete cycles to
remove air in system lines.
Oil and Filter Change
Every 1000 hours or yearly change the reservoir oil and replace the reser-
voir outlet filter.
1. Shut off engine. Close air shutoff valve above reservoir. Loosen reservoir
cover slowly and carefully. Let pressurized air escape. Remove cover and
O-ring. Discard O-ring if damaged or worn.
2. Remove drain plug on bottom of reservoir and drain the oil.
