HULK Power Air Compressors
Drain Valve
1. Make sure the drainage valve (g 5) is closed
and not in the open position.

Adjusting the air pressure
Your air compressor is supplied with an air pressure
regulator. This regulator adjusts the air pressure
supplied to the hose.
• To increase air pressure, turn air regulator
knob (g 2.10) clockwise.
• To decrease air pressure, turn air regulator
knob counterclockwise.
• Use the outlet pressure gauge (g 7.8) to see
the resulting pressure.
Shutting off your compressor
1. Push down the pressure switch to the OFF
position (g 6.0).
2. Unplug the compressor from the electical power.
3. If not draining the tank, reduce tank pressure
through the air hose.
4. Drain the tank by slowly opening the drain valve
(g 5.1). 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 dicult. 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.
Maintenance
Daily
● Before each use,
1. check for any unusual noise or vibration.
2. be sure all nuts and bolts are tight.
● After each use, drain condensation from the air
tank.

Pressure Switch
2. Check that the pressure switch is pushed
down, in the OFF position (g 6.0).
3. Ensure that the power supply you are going to
use is operating normally.
4. Insert the power supply cord into the power
supply socket.
5. Turn the pressure switch on, lifting the button
to the up position.
6. On the reservoir pressure gauge (g 7.5), you
can watch pressure build in the tank until the
pump stops at the factory-set pressure, about
115 to 120 psi.
7. This rst time running your compressor and
periodically thereafter, check for air leaks. If
the gauge indicates pressure is going down in
the tank or you hear leakage, you could apply
soapy water to all joints in the air transport
piping. Tighten these joints if bubbles form.
