Replace the seals of the fitting, clean or replace
the filter.
Clean the air ducts in the conveyor. Ventilate
the work area. Reset the thermal cutout. On
lubricated and V type models, check oil level
and quality. On V models, have the voltage
checked.
Activate the on/off switch. Ventilate the work
area. Wait a few minutes. The compressor will
restart independently. On V, 3 HP models, reset
