compressor to cool prior to servicing.
A dirty air filter will not allow the compressor to operate at full capacity. Keep
the air filter clean at all times.
1. Remove the air filter cover.
2. Remove the air filter from filter cover.
IMPORTANT: Do not operate the compressor with the air filter removed.
3. Place new air filter into filter cover. Refer to the "Repair Parts" for the
correct part number.
4. Replace air filter cover and lock into place.
Motor
The motor has an automatic reset thermal overload protector. If the motor
overheats for any reason, the overload protector will shut off the motor. The
motor must be allowed to cool down before restarting. The compressor will
automatically restart after the motor cools.
If the overload protector shuts the motor off frequently, check for a possible
voltage problem. Low voltage can also be suspected when:
1. The motor does not get up to full power or speed.
2. Fuses blow out when starting the motor; lights dim and remain dim when
motor is started and is running.
Overfilling with oil will cause premature compressor
failure. Do not overfill.
Hot surfaces. Risk of burn. Compressor heads are
exposed when filter cover is removed. Allow
