13. CHANGING FLUID OF HYDRAULIC TANK
Change the hydraulic fluid in the hydraulic unit tank at regular intervals while paying attention to
the following considerations.
(1) Maintain the oil level of hydraulic fluid in the tank at the correct level; make sure
that the pump unit does not suck in air.
(2) Keep the hydraulic fluid clean.
(3) Clean the strainer periodically to avoid clogging which will lower the pump flow
rate.
