sure is approximately 20 psl.
n. Drain water from air tank.
WATER WILL CONDENSE IN THE AIH TANK.
IF NOT DRAINED, WATER WILL CORRODE
AND WEAKEN THE AIR TANK CAUSING A
RISK OF AIR TANK RUPTURE.
With tank pressure at approodmately 3D psi,, open
the drain cock and allow moisture to drain.
NOTE
H drain cock valve is plugged, retease all air pres­
sure. The valve can tt»n be removed, cleaned, than
rdnstallaef..
12. After the water has been drained, dose the drain
cock. The air compressor can now be stored.
MAINTENANCE
WARNING
UNIT CYCLES AUTOMATICALLY WHEN POWER IS ON. WHEN DOING MAINTENANCE, YOU MAY
BE EXPOSED TO VOLTAGE SOURCES, COMPRESSED AIR OR MOVING PARTS. PERSONAL
INJURIES CAN OCCUR. BEFORE PERFORMING ANY MAINTENANCE OR REPAIR, UNPLUG THE
COMPRESSOR AND BLEED OFF ALL AIR PRESSURE.
Air Filter-Inspection
NOTE
Keep the air filter clean at alt times. Do not oper­
ate tfie compressor with the air fitter removed.
A dirty air filter will not allow the compressor to operate
at full capacity, Batore you use the compressor, check
the air filter to be sure it is clean.
If It Is dirty, simply pull It out. You may wash it with a mild
detergent and warm water, or repaace If,
Check \^lve - R«|)lacement

WARNING

IF THE SAFETY VALVE DOES NOT WORK
PROPERLY, OVER-PRESSURIZATION MAY
OCCUR, CAUSING AIR TANK RUPTURE OH
AN EXPLOSION. OCCASIONALLY PULL
THE RING ON THE SAFETY VALVE TO
MAKE SURE THAT THE SAFETY VALVE
OPERATES FREELY. IF THE VALVE IS
S T U C K O R D O E S N O T O P E R A T E
SMOOTHLY, IT MUST BE REPLACED WITH
THE SAME TYPE OF VALVE.
Motor
The motor has an automatic reset thermal overload pro-
tectof. if the motor overheats for any reason, the over-
10ШЗ protector will shut off the motor. The motor must be
allowed to cool down before restarting. The compressor
will automatically re-atart after the motor cools.
If th© overload protector shuts the motor off frequefilly,
check for a possible voltage problem. Low volti^e can
also be suspected when:
1 . the motor aoee not get up to full power or speed;
2. fuses blow out When starting the motor; lighte dim and
remain dim when motor is started and is running.
