equipped with an automatic reset thermal overload protector which will shut off
motor if it becomes overheated, if the thermal overload protector is actuated, the
motor must be allowed to cool down before start-up is possible.
NOTE: The motor will automatically restart without warning if the unit is left
plugged in to an outlet with the Auto-On/Off switch in the on position.
DRAINING THE TANK
Condensation will accumulate in the
tank. To prevent corrosion of the tank from the inside,
this moisture must be drained at the end of every
workday. Be sure to wear protective eyewear. Relieve the
air pressure in the system and open the drain valve on
the bottom of the tank and tilt tank to drain.

NOTE: In cold climates, drain the tank after each use to reduce problems with
freezing of water condensation.
CHECKING THE SAFETY VALVE (Figure 5)
Check the safety valve by performing these three steps:
1. Plug the compressor in and run until shut-off pressure is reached.
2. Wearing safety glasses, pull out on the safety valve ring to release pressure
from the tank.
3. The safety valve should close automatically at approximately at 40-50 PSi.
if the safety valve does not allow air to be released when you pull out
on the ring, or does not close automatically, it must be replaced.

3. Perform the daily maintenance schedule.
