prevent debris from entering spindle.
6. Make sure that O--ring is positioned to top of spindle

age spindle seals. Pneumatic grease guns, there-
fore, are not recommended to be used for greasing
of spindle housings.

fittings on housing and fill housing cavity with grease un-
til grease starts to come out of lower seal.
