OPERATION
Pressure Switch: Auto/Off Switch-In the AUTO position , the compressor shuts off automatically
when tank pressure reaches the maximum preset pressure. In the OFF position , the compressor
will not operate. This switch should be in the OFF position when connecting or disconnecting the
power cord from the electrical outlet or when changing air tools.
Regulator: The regulator controls the amount of air pressure released at the hose outlet.
Safety Valve: This valve automatically releases air if the tank pressure exceeds the preset maximum.
Discharge Tube: This tube carried compressed air from the pump to the check valve. This tube
becomes very hot during use. To avoid the risk of severe burns, never touch the discharge tube.
Check Valve: A-one-way valve allows air to enter the tank ,but prevents air in the tank from flowing
back into the compressor pump.
Handle: Designed to move the compressor.
WARNING!
Never use the handle on wheeled units to lift the unit completely off the ground.
Drain Petcock- This valve us located on the bottom of the tank. Use this valve to drain moisture from
the tank daily to deduce the risk of corrosion.
Reduce tank pressure below 10psi, and then drain moisture form tank daily to avoid tank corrosion.
Drain moisture from tank by opening the drain petcock located underneath the tank.
LUBRICATION
This is an oilless product and does not require lubrication to operate.
BREAK-IN PROCEDUR
CAUTION!
Do not attach air chuck or other tool to open and of hose until start-up has been
completed and unit checks ok.
IMPROTANT: Do not operate compressor before reading instructions or damage may result.
1. Turn regulate fully clockwise to open airflow.
2. Turn switch to OFF position and plug in power cord.
3. Turn switch to AUTO position and run unit for 30 minutes to break in the pump parts.
4. Turn regulator knob fully counterclockwise. Compressor will build to maximum preset pressure
and shut off.
5. Turn regulator knob clockwise to cause air to bleed off. Compressor will result at a preset pressure.
6. Turn regulator knob counterclockwise to shut off the air and turn switch to off position.
7. Attach chuck or other tool to open end of hose, Turn the regulator on. In the AUTO position, the
compressor pumps air into the tank. It shuts off automatically when unit reaches its maximum
preset pressure. In the OFF position, the pressure switch cannot function and the compressor will
not operate. Make sure switch is in OFF position when connecting or disconnecting power cord
from electrical outlet.
MOISTURE IN COMPRESSED AIR
Moisture in compressed air will from into droplets as it comes from an air compressor pump.
When humidity is high or when a compressor is in continuous use for an extended period of time, this
moisture will collect in the tank. When using a paint spray or sandblast gun, this water will be carried
from the tank through the hose, and out of the gun as droplets mixed with the spray material.
IMPORTANT:
This condensation will cause water spots in a paint job, especially when spraying other
than water based paints. If sandblasting , it will cause the sand to case and clog the gun rendering it
ineffective . A filter in the air line ,located as near to the gun as possible ,will help eliminate this moistu-
re.
SAFETY VALVE
WARNING!
Do not remove or attempt to adjust the safety valev!
This valve should be checked under pressure occasionally by pulling the ring by hand. If air leaks after
ring has been released, or valve is stuck and cannot be actuated by ring, it MUST be replaced.
REGULATOR KNOB
(figure 4)
1. This knob controls air pressure to an air-operated tool or paint spray gun.
2. Turn clockwise to increase air pressure at outlet. When desired pressure is reached, locked with
nuts.
3. To lower air pressure at outlet, turning counterclockwise.
4. Turn fully counterclockwise to shut off flow of the air completely then push knob down.
TANK PRESSURE GAUGE
