IV. Maintenance
(continued)
8. Check to be sure that the O-ring
is still in place at the open end
of the pre-filter housing. (If the
O-ring falls out, lay it back into
the groove at the opening of the
filter housing (see figure 24) and
press into place with your fingers.
A small amount of petroleum jelly
can be applied to the O-ring to
help hold it in place. Do not use
vegetable, animal or motor oil.)
Replace the pre-filter housing
and secure by turning clockwise
until hand-tight only. DO NOT
OVER-TIGHTEN. Never use
the housing wrench to tighten
the pre-filter housing—the
housing wrench is only for
loosening the filter housings.
