INSPECTION AND MAINTENANCE
1. WARNING! Always unplug the Air Compressor from its electrical outlet
before performing any inspection, maintenance, or cleaning.
2. Before each use: Inspect the general condition of the Air Compressor. Check for
misalignment or binding of moving parts, cracked or broken parts, damaged
wiring, damaged air hose, and any other condition that may affect its safe
operation. If abnormal noise or vibration occurs, have the problem corrected
before further use. Do not use damaged equipment.
3. Daily, before switching the compressor on: Make sure the level of compressor
oil is adequate. For instructions on checking and, if necessary, filling the Air
Compressor with oil, see pages 10 and 11 of this manual.
4. Daily: Purge the Tank (55) daily of all air and moisture to prevent corrosion. To do
so, unscrew the Drain Valve (67) two to three turns. Do not unscrew the Drain
Valve more than three turns. When all the air pressure and moisture is released
from the Tank, retighten the Tank Drain Valve.
(See Figure F.)
5. Store the Air Compressor in a clean, dry, location.
8. NOTE: If it is necessary to quickly
depressurize
the Air Compressor, turn off the
Air Compressor by pushing DOWN on the “On/Off” Pressure Switch (50). Then,
pull OUT on the ring on the Safety Valve (51) to quickly release stored air pres-
sure. (See Figure D.)
9. When finished using the Air Compressor, turn it off by pushing DOWN on the
”On/Off” Pressure Switch (50). Unplug the Power Cord (49) from its electrical
outlet. Squeeze the trigger on the air tool being used to release all stored air
pressure from the system, and disconnect the air hose and air tool from the Air
Compressor. Then, open the Drain Valve (67) to release all remaining com-
pressed air from the Tank Assembly (55). (See Figure F.)
10. NOTE: The Air Compressor is equipped with a Protector (45) button. Should the
Air Compressor overheat while in use, the machine will automatically shut down.
If this happens, push DOWN on the “On/Off” Pressure Switch (50). Wait for the
unit to cool off (usually 5-10 minutes). Then, press the Protector (45) button and
pull UP on the “On/Off” Power Switch (50)to restart the Air Compressor. If
overheating is a reoccurring problem, make certain that the extension cord used
is of the proper gauge and length for this unit’s power requirements - as explained
on page 7.
