the knob. Rotate the ring in a counterclockwise direction and tighten it against the knob to
secure the setting. (See Figure C).
4. Attach hose to air-flow valve, then tool to hose, turn on air-flow valve to supply air
pressure shown on gauge (70) to tool.
NOTE: When the maximum air pressure, 100 PSI, is reached as indicated by the Tank
Pressure Gauge (26), the motor will stop. The Compressor will automatically restart when the
air pressure drops below 85 PSI. (See Figure C.)
To Stop The Compressor:
1. Push the ON/OFF Power Switch (45) to its “OFF” position.
2. Turn air-flow valve to off (handle perpendicular to outlet pipe). Press trigger on tool to
relieve air pressure in hose. Disconnect hose from air-flow valve
3. Relieve the Air Tank pressure and remove moisture by opening the Tank Drain Valve (54).
Turn the valve slowly counter-clockwise until the pressure is relieved. Then, retighten the
Drain Valve (54). (See Figure B.)
4. Allow the Air Compressor to completely cool. Then store the unit in a clean, dry, safe
location out of reach of children.
Inspection, Maintenance, and Cleaning
1. WARNING! Make sure the ON/OFF Power Switch (45) of the Air Compressor is in its
“OFF” position, the unit is unplugged from its electrical outlet, and air is drained from the
Tank (53) before performing any inspection, maintenance, or cleaning procedures or leaving
it unattended.
2. Before each use, inspect the general condition of the Air Compressor. Check for loose screws,
misalignment or binding of moving parts, cracked or broken parts, damaged electrical wiring,
loose air fittings, and any other condition that may affect the safe operation of the
Compressor. If abnormal noise or vibration occurs, have the problem corrected before further
use. Do not use damaged equipment.
3. Daily, purge the Air Tank (53) of all air and moisture to prevent corrosion. To do so, slowly
and carefully unscrew (no more than four threads) the Tank Drain Valve (54) until the
compressed air and condensation begins to be released from the Tanks. Allow sufficient time
for all of the air and condensation to escape from the Tanks. Then, firmly re-tighten the Drain
Valve.
4. CAUTION! All maintenance, service, or repairs not mentioned in this manual must only be
performed by a qualified service technician.
5. To replace the Fuse (43), unscrew the fuse and replace with a 250V, 3A fuse.
