RELIEVING HYDRAULIC SYSTEM PRESSURE
DO NOT disconnect or remove any hydraulic system lines or fitting unless engine is shut
down and hydraulic system pressure has been relieved. Tighten all connections before
applying pressure. Escaping hydraulic fluid under pressure can penetrate the skin,
causing injury to personnel.
At operating temperature, hydraulic oil is hot. Allow hydraulic oil to cool before removing
any hydraulic fitting. Failure to follow this warning may result in injury to personnel.
To prevent injury, wear protective eye covering.
Sudden movement of vehicle can cause injury to persons on or near the machine.
Remove filler cap from hydraulic reservoir.
RELIEVING AIR SYSTEM PRESSURE
1. Open drain valves and let air bleed off.
2. Depress brake pedal.
1. Before beginning a task, find out how much repair, modification, or replacement is needed to fix the equipment
as described in this manual. Sometimes the reason for equipment failure can be seen right away and complete
teardown is not necessary. Disassemble the equipment only as far as necessary to repair or replace damaged
or broken parts.
2. All tags and forms attached to the equipment must be checked to learn the reason for removal from service.
Check all Modification Instructions (MIs) and Technical Bulletins (TBs) for equipment changes and updates.
3. In some cases a part may be damaged by removal. If the part appears to be good, and other parts behind it are
not defective, leave it on and continue the procedure. Here are a few simple rules:
a. Do not remove dowel pins or studs unless loose, bent, broken, or otherwise damaged.
b. Do not pull bearings or bushings unless damaged. If you must get at parts behind them, pull out bearings
or bushings carefully.
Replace all gaskets, seals, preformed packings, O-rings, cotter pins, spring pins, self-locking nuts, and
