pump intake and exhaust valves.
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.
