WATER WILL CONDENSE IN THE AIR TANK.
tF NOT DRAINED, WATER WILL CORRODE
AND WEAKEN THE AIR TANK; CAUSING A
RISK OF AIR TANK RUPTURE.
10. With tank pressure at approximately 20 psi., open
the drain cock and allow moisture to drain. Turn drain
T-handle counterclockwise to open.
NOTE
If the drain cock valve is plugged, release all air
pressure. The valve can then be removed,
cleaned, and reinstalled.
11. After the water has been drained, close the drain
cock (turn clockwise). The air compressor can now
be stored.
MAINTENANCE
WARNING I
UNIT CYCLES AUTOMATICALLY WHEN POWER tS ON. WHEN DOING MAINTENANCE, YOU MAY
BE EXPOSED TO VOLTAGE SOURCES, COMPRESSED AIR OR MOVING PARTS. PERSONAL
INJURIES CAN OCCUR. BEFORE PERFORMING MAINTENANCE OR REPAIR UNPLUG THE UNIT
AND BLEED OFF ALL AIR TANK PRESSURE. NEVER OPERATE THE UNIT WITH THE BELT
GUARD REMOVED.
Air Compressor
A clean air compressor runscooler and provides longer
service. Clean or blow off fins and any other parts ofthe
air compressor that collect dust or dirt. Do not place
rags, containers or other material on or against the venti-
lation openings inthe belt guard. Adequate ventilation is
necessary to maintain proper air compressor operating
temperature,
Air Filter - Inspection and Replacement
NOTE
Keep the air filter clean at all times. Do not oper-
ate the compressor with the air filter removed.
A dirty air filter will not allow the compressor to operate
at full capacity. Before you use the compressor, check
the air filter to be sure it is clean.
If it is dirty, replace it with a new filter. The filter may be
removed by using a pair of needle nosed pliers or a
screwdriver. Pull or pry out the old filter. Push in the new
air filter.
Oil - Checking and Changing
Overfilling with oil will cause premature
compressor failure. Do not overfill=
Check oil level in the crankcase daily. Remove the oil fill
plug (Key no. 77, pg. 15). The oil level should be even
with the top of the fill hole and must not be allowed to be
lower than 3/8" from the top (6 threads) at any time. It is
recommended that the oil be changed after every 100
hours of operation. Todrain the oil, remove the oil drain
plug and collect the oil in a suitable container. Be sure to
replace the plug securely before adding new oil Use a
special compressor oil such as Sears 9-16426 or SAE
20-20W SF or SG motor oil (Crankcase oil capacity is 16
fluid ounces.) Under extreme winter conditions use SAE
b
10W. Multi-viscosity oil (10W30) will leave carbon
deposits on critical components which will reduce per-
formance and compressor life.
Check Valve - Replacement
1. Release air pressure from the air tank.
2. Loosen the top and bottom tube nuts and remove the
outlet tube,
3. Unscrew the check valve (turn counter-clockwise)
using socket wrench. (7/8").
4. Check that the valve disc moves freely and that the
spring holds the disc in the upper, closed position.
The check valve may be cleaned with a solvent- such
as paint thinner or carburetor cleaner.
5. Apply sealant to the check valve threads. Reinstall the
check valve (turn clockwise). Do not over tighten.
6. Replace the outlet tube and tighten top and bottom
tube nuts.
Safety Valve - Inspection
WARNING
J
IF THE SAFETY VALVE DOES NOT WORK
PROPERLY OVER-PRESSURIZATION MAY
OCCUR, CAUSING AIR TANK RUPTURE OR
EXPLOSION. OCCASIONALLY PULL THE
RING ON THE SAFETY VALVE TO MAKE
SURE THAT THE SAFETY VALVE OPER-
ATES FREELY. IF THE VALVE IS STUCK OR
DOES NOT OPERATE SMOOTHLY, IT MUST
BE REPLACED WITH A VALVE HAVING THE
SAME PRESSURE RATING.
Motor
The motor has a manual thermal overload protector, tf
the motor overheats for any reason, the overload protec-
tor wilt shut off the motor. The motor must be allowed to
cool down before restarting. Turn the unit off. To restart,
depress the red reset button located on the end of the
motor and turn the unit on.
