Inspection and Maintenance of Hydraulic Equipment
CAUTION: During operation, the parts of the
hydraulic system become very hot.
Allow the machine to cool down before beginning
inspection or maintenance.
1. Park the machine following the same procedures as
described on page 7-7 for preparation of inspection/
maintenance work.
2. Begin servicing hydraulic components only after
components, hydraulic oil and lubricants are completely
cooled, and after releasing residual circuit pressures.
2.1 Release internal pressure.
2.2 Be sure to relieve the air pressure from the hydraulic oil
tank by pressing air bleed valve (1).
2.3 Allow the machine to cool down.
Note that servicing heated and pressurized hydraulic
components may cause hot parts and/or oil to fly off or
escape suddenly, possibly resulting in personal injury.
Keep body parts and face away from plugs or screws
when removing them.
Hydraulic components may be pressurized even when
cooled.
Service only on a flat, solid and level surface.
