DRAINING AND REFILLING THE HYDRAULIC OIL

SYSTEM
Before opening any portion of the hydraulic oil system -
namely removing the reservoir tank cover, filler cap or
disconnecting any hoses, it is extremely important that
the opening points and immediate areas around these
points be cleaned with a solvent and blown air dry.
Almost immediate component failure will result if for-
eign material is allowed to enter the system. Avoid
opening the hydraulic system in dust laden areas.
Do not open hydraulic lines or components that are
under pressure. Shut off engine and make sure engine
cannot be started.
Do not drain oil or open system if components are hot
to touch. Wait until oil cools.
Do not attempt to reclaim drained oil for reuse.
