To ensure efficient operation and longer life of the air compressor" oQtfit, a routine maintenance schedule should
be prepared and followed. The following routine maintenance sch_ble is geared to an outfit in a normal work-
ing environment operating on a daily basis. If necessary, the sche_ul_ should be modified to suit the conditions
under which your compressor is used. The modifications will dep_n_ upon the hours of operation and the
working environment. Compressor outfits in an extremely dirty an_l/6f hostile environment will require a greater
frequency of all maintenance checks. Lubricate compressor motdr _cording to manufacturer's instructions,
which are attached to your motor.
A clean air compressor runs cooler and provides longer service, qle_n or blow off fins and any other parts of
the air compressor that collect dust or dirt. Do not place rags, cor_taln_ersor other material on or against the
ventilation openings in the belt guard. Adequate ventilation is neces_lry to maintain proper air compressor
operating temperature. =
