D. Hydraulic System

Inspection and Maintenance of Hydraulic

Equipment

IMPORTANT: Never adjust parts of engine fuel system or

hydraulic equipment.

CAUTION: When checking and/or servicing the

hydraulic components, pay special attention to the

following points.

1. Be sure that the machine is parked on a level, firm

surface before servicing hydraulic equipment.

2. Lower the bucket to the ground and stop the engine.
3. Begin servicing hydraulic components only after

components, hydraulic oil and lubricants are completely

cooled, and after releasing residual pressure.

3.1 Before checking and/or servicing the hydraulic system,

be sure to release the residual pressure from the

cylinder circuits of the boom, arm and the bucket,

swing piping and pilot piping. An accumulator can be

installed on some models of this machine as an option

to be capable of moving the front attachment for

specified time (around 10 seconds) after stopping the

engine.

3.2 Bleed air from the hydraulic oil tank to release internal

pressure.

3.3 Immediately after operation, all hydraulic components

and hydraulic oil or lubricants are hot and highly

pressurized. Begin inspection and/or maintenance

work only after the machine has cooled down.

Servicing heated and pressurized hydraulic

components may cause plugs, screws and/or oil to fly

off or escape suddenly, possibly resulting in personal

injury. Hydraulic components may be pressurized even

when cooled.

Keep body parts and face away from the front of plugs

or screws when removing them.

3.4 Even after air pressure in the hydraulic oil tank is

released, when the machine is parked on a slope, the

oil pressure in the travel motor and the swing motor

circuits are maintained at high pressure as the reaction

force of the machine weight is constantly applied

to the travel motor. Never check and/or service the

machine when it is parked on a slope.
