Head Bolts - Check the torques of the head bolts after the first five hours of operation.
To ensure efficient operation and longer life of the air compressor outfit, a
routine maintenance schedule should be prepared and followed. The above
routine maintenance schedule is geared to an outfit in a normal working
environment operating on a daily basis. If necessary, the schedule should be
modified to suit the conditions under which your compressor is used. The
modifications will depend upon the hours of operation and the working
environment. Compressor outfits in an extremely dirty and/or hostile
environment will require a greater frequency of all maintenance checks.
1. Before starting compressor, pull
the ring on the safety valve to
make sure that the safety valve
operates freely. If the valve is
stuck or does not operate
smoothly, it must be replaced
with the same type of valve.
