pointing away from the oil reservoir.
Always keep the hydraulic oil clean.
Hydraulic Oil Filter
The three in-line filters are accessed through the right
hand cooler door. The filters are serviceable, and can be
cleaned. If the housing or O-rings have damage or wear
contact a Rayco dealer or Rayco for replacement parts.

Remove the filter from the machine and cap lines to
prevent contamination. To disassemble the filter, a vise
and a 1 1/2'' inch wrench is needed.

of the filter housing (E) to prevent rotation of the filter
housing when removing the cap(A). Note: Do not
overtighten the vise and damage the housing.
• Using the wrench, loosen the cap (A) and remove the
components noting the placement of the springs (B
and D).
• Clean all components including the filter (C) using
brake parts cleaner and inspect O-rings for damage (F).
• Reassemble the filter and install in the machine.
