MAINTENANCE
OUTLINE OF SERVICE
Inspection and maintenance includes inspection of the hydraulic oil level, replacement of filters, and changing
the hydraulic oil.
When removing high-pressure hoses, check that there is no damage to the O-ring. If any damage is found,
replace.
If the hydraulic filter element, strainer, or other parts have been replaced or washed, or if any hydraulic equip-
ment has been repaired or replaced, or hydraulic piping has been removed, it is necessary to bleed the air
from inside the circuit.
