FILTER AND RESERVOIR

A filter assembly (2, Figure 3-6) is mounted on the right
upright (1) and filters the grease when the grease supply
is refilled through the "quick fill" fittings.
Grease is pumped into the filter through a hose (4)
routed from the Service Center and then flows out the
filter through a hose (3) to the reservoir (5). A vent hose
(7) purges air from the reservoir as it is being filled and
prevents a vacuum as grease is pumped out.
A cap (6) allows the reservoir to be drained if desired
and a plate secured on the end of the reservoir (frame
torque tube) can be removed if the reservoir requires
cleaning.
