SOLUTION
1. Source electric to the compressor is either the incorrect voltage,
insufficient wire size to carry the load, the fuse box or breaker box is
not sufficient to carry the load requirements to the compressor.
2. Any wiring other than what is stated in the manual could cause a
malfunction (see Wiring Section).
3. Make sure voltage is correct with the motor wiring (see Wiring
Section).
4. The entire electrical system should be checked by a certified
electrician. The incoming wires and the compressor electrical
connections should be checked. Loose connections will cause
malfunctions.
5. Check that wire size is rated for the current of the compressor.
State and local codes vary widely and need to be checked before
installation.
6. The breaker and fuses required for this unit must be time delay.
A tripped breaker or blown fuse may result from a direct short to
ground, high current draw, improper wiring, incorrect fuse or breaker
size and/or type. This needs to be evaluated by a service center or
certified electrician.
7. Check and reset if necessary. If the overload trips after the initial
reset, refer to the section of the manual that covers this issue.
1. Source electric to the compressor is either the incorrect voltage,
insufficient wire size to carry the load, the fuse box or breaker box is
not sufficient to carry the load requirements to the compressor.
2. The entire electrical system should be checked by a certified
electrician. The incoming wires and the compressor electrical
connections should be checked. Loose connections will cause
malfunctions.
1. Make sure the drain valve at the bottom of the tank is closed.
2. Check the entire system for leaks, including the compressor unit and
any piping attached to the compressor
3. Make sure that the air intake of the compressor is not blocked in any
way.
1. Check to make sure the compressor has not been damaged in the
shipping or installation. Make sure the belt guard was not damaged.
Belt guard should not be making contact with flywheel or pulley.
2. Check all bolts and nuts to assure they did not loosen during
shipping.
3. Check to assure pulley and flywheel are correctly tightened.
A small amount of oil may be released with the high pressure air that
vents through the air filter.
Do not remove air fi lter housing or perform any
maintenance with pressure in the air end or air
pressure tank.
