For the first weeks, the compressor needs time to “break in.” The belt requires time to stretch

and fit into the surface of the pulleys. The piston rings need time to seat themselves into the

cylinder walls, and bearings need to wear into place. For the first 100 hours or so, the

compressor will consume higher than normal amounts of oil until the break in process is

complete.

FIRST MONTH MAINTENANCE

• Check oil level at the beginning of every week, fill as needed, see oil subsection.

• Check belt tension at the beginning of each week and tighten as required, see belt

tension subsection.

• Check bolts, pulley clamp screws, and jam nuts for tightness. Torque if necessary (see

bolt torques subsection)

START-UP

If the compressor is equipped with an automatic start-stop control (with pressure switch

unloading), it is automatically unloaded upon starting, and will automatically load after attaining

running speed. Simply throw the power switch to start the unit.

All gas units are equipped with pilot valve controls and should be manually unloaded prior to

start up. To manually unload the compressor in order to achieve an unloaded start, release

the pilot valve lever BEFORE starting the compressor.
