CARE OF JACKS
1.
Coat all surfaces with a thin film of light oil when not
in use.
2.
For long periods of storage, the jacks should be
covered with a rust-preventive compound and
stored in a dry place.
3.
Periodically check hydraulic fluid level in push-pull
hydraulic jacks. Stand the pump on end before tak-
ing out the fill plug, then fill with oil. Make sure the
ram is in the retracted position when checking level
of oil and when filling.
4.
Ratchet lever jacks should be well greased. 4 thin
coat applied with hand or brush is sufficient for all
movable parts except the bushings. The bushings
should be filled with grease in the small hole-pro-
vided for greasing purposes. Keep rack sides and
front greased, but do not grease the rack teeth.
