of the sight glass (1) with all of the hydraulic cylinders
retracted.
• Remove cap (2) and add hydraulic oil to correct
level as needed.
• Hydraulic oil should be changed yearly or after
every 1,000 hours of use.
• Hydraulic Filter — Replace the hydraulic filter (3)
yearly, after every 1,000 hours of use, or when the
filter indicator (4) is in the red area.
• Hoses and Fittings — Inspect all hoses and fittings
for leaks weekly. Check hoses for cracks, fraying, and
rubbing. Close valves (5) and replace the necessary
hoses and/or tighten fittings.

• The canister filter element can be cleaned by
removing it from the canister filter housing and
using low-pressure water or air to remove any
debris. Once clean, the filter should be allowed
to dry before installing.
Make sure the canister filter element is properly
seated in the housing before tightening the filter
element retaining wing nut.
Make sure the two jam nuts are properly adjusted so
that the filter housing door will not cut the filter
housing seal when vacuum is applied.
