Your air compressor is supplied with an air pressure

regulator. This regulator adjusts the air pressure

supplied to the tools through the hose.

●

To increase air pressure, turn air regulator knob

(fig.7,E) clockwise.

●

To decrease air pressure, turn air regulator knob

counterclockwise.

●

Use the outlet pressure gauge (fig.7,B) to see the

resulting pressure.

Shutting off your compressor

1. Push the red pressure switch button down to the

OFF position (fig.6).

2. Unplug the compressor from the electrical power.

3. If not draining the tank, reduce tank pressure

through the air hose.

4. Drain the tank by slowly opening the drain valve

(fig.5). Place a catch basin under the valve to

protect the surface from water damage.

Cold Weather Starting

Temperatures below freezing (32 °F / 0 °C) cause the metal parts of your air compressor to contract and that

makes starting more difficult. To assist the air compressor in starting in cold weather, follow these tips:

1. Try to keep the air compressor stored in temperatures above 32 °F (0 °C).

2. Open the air tank drain valve and release all air pressure from the air tank before attempting to start in

cold weather. (After air is released from air tank, close drain valve.)

3. Pull the ring on the safety valve before each use to make sure the valve is functional.

4. Plug the air compressor directly into a 120 volt electrical outlet. Do not use an extension cord when

starting your air compressor in cold weather.

• Risk of unsafe operation. Firmly grasp air hose in hand when installing or disconnecting to prevent hose

whip.

• Risk of bursting. Drain air tank daily. Water will condense in air tank. If not drained, water will corrode

and weaken the air tank causing a risk of air tank rupture.

1. Set the Power Switch to the OFF (0) position.

2. Unplug the power cord from the receptacle.

3. Set the outlet pressure to zero on the regulator.

4. Remove any air tools or accessories.

5. Open the drain valve allowing air to bleed from the tank. After all of the air has bled from the tank, close

the drain valve to prevent debris build-up in the valve.
