PREPARATION

1. Check all nuts and bolts are tight before starting.

2. Before Starting the Compressor; Ensure power switch is set to “OFF”.

3. Plug compressor in to socket.

4. Pull up the red power switch and tun for 30 minutes to break in pump

parts.

5. Bleed air by turning the regulator know fully counter clockwise.

6. Attach tool and hose to the compressor using the quick release

couplings.

OPERATION & ADJUSTMENT

1. The compressor is controlled by a pressure switch. It can be

stopped automatically as the pressure increases to the maximum

and restarted as pressure decreases to the minimum. The rated

pressure has been adjusted during the manufacturing process -

do not alter it carelessly.

2. As soon as the motor is switched o the compressed air in the

discharge pipe should be released through the release valve

under the switch. This is a necessary condition before restarting

or the motor will be damaged.

3. The output pressure of compressed air can be regulated by using the

regulating valve. turn the regulation valve knob clockwise to

increase the pressure.

4. When the compressor needs to be stopped, set the power switch to

the ‘OFF’ position.

5. If the compressor should overheat, the Thermal Overload will

intervene and shut down the compressor. Should this happen, switch

OFF the machine by pushing the STOP/START switch downwards, and

wait for at least 5 minutes before pressing the red RESET button

underneath the air lter and try to start the compressor again.

1. Never unscrew any connecting parts while the tank is pressured.

2. Never disassemble any electrical parts before disconnecting the plug.

3. Never adjust the safety valve carelessly.

4. Never use the compressor when the voltage is too low or too high.

5. Never use an electric wire more than 5m long with less than a 1.5mm²

section rated to 16A.

6. Never disconnect the plug to stop the compressor. Set the switch knob

to“o” and follow instructions on page 5.

7. If the release valve doesn’t work when the motor is stopped nd the

cause immediately so as not to damage motor.

8. After motor has been switched o and compressed air has been

safely discharged, Switch o and disconnect the plug to cut o the

power supply. Never leave compressor plugged in when not in use.

9. Never operate near ammable gas or vapour.

WARNINGS

MAINTENANCE

1. Do not carry out any maintenance whilst compressor is on - ensure

motor is not running, compressed air and condensation is bled and

compressor is disconnected from any power supply (see pages 5 + 6).

2. Pull ring on safety valve an allow it to snap back in to normal position.

Safety valve must be replaced if it cannot be actuated or it leaks air

after ring is released.

3. Turn compressor o and release pressure from system. Drain moisture

from tank by opening drain cock located on the underside of the tank.

4. Clean dust and dirt from the motor, tank, airlines, pump and cooling

ns while compressor is o.

5. Unclip the air lter cover, remove the lter and blow away any loose

dirt. If damaged or badly contaminated, it must be replaced.

6. Clean the ns of the compressor cylinder and the cylinder head to

receiver pipe.

7. Locate the compressor as far away from spraying area as possible,

Extending the hose will help prevent overspray which may clog the

lter. Take care not to over extend.

8. Do not lubricate. Oil-Less compressors require no lubrication.

Symptom Possible Cause (s) Corrective Action

Compressor will

not run

4. Thermal overload open

5. Pressure switch bad

1. Plugged in? Check fuse/breaker or motor

overload

2. Replace blown fuse

3. Reset, determine cause of problem

4. Motor will restart when cool

5. Replace

Symptom Possible Cause (s) Corrective Action

Motor hums but cannot

run or runs slowly

1. Defective check valve or

unloaded

2. Poor contacts, line voltage

low

3. Shorted or open motor

winding

1. Replace or repair

2. Check connections, eliminate extension cork if

used, check circuit with voltmeter

3. Replace motor

DANGER! Do not disassemble check valve with air

in tank; bleed tank

Fuses blow/circuit

breaker trips

repeatedly

CAUTION! Never

use an extension cord

with this product

1. Incorrect size fuse, circuit

overloaded

2. Defective check valve or

unloaded

1.Check for proper fuse, use time-delay fuse.

Disconnect other electrical appliances from circuit or

operate compressor on its own branch circuit

2.Replace or repair

DANGER! Do not disassemble check valve with air

in tank; bleed tank

Thermal overload

protector cuts out

repeatedly

1. Low voltage

2. Clogged air filter

3. Lack of proper

ventilation/room temperature

too high

4. Check valve malfunction

Compressor valves failed

1. Eliminate extension cord, check with voltmeter

2. Clean filter (see Maintenance section)

3. Move compressor to well ventilated area

4. Replace

5. Replace valve assembly

DANGER! Do not disassemble check valve with air

in tank; bleed tank

Knocks, rattles,

excessive vibration

1. Loose bolts, tank not level

2. Defective bearing on

eccentric or motor shaft

3. Cylinder or piston ring is

worn or scored

1. Tighten bolts, shim tank to level position

2. Replace

3. Replace or repair as necessary

Tank pressure drops

when compressor shuts

off

1. Loose drain cock

2. Check valve leaking

3. Loose connections at

pressure switch or regulator

1. Tighten

2. Disassemble check valve assembly, clean or

replace

3. Check all connections with soap and water

solution and tighten

Compressor runs

continuously and air

output is lower than

normal/low discharge

pressure

1. Excessive air usage,

compressor too small

2. Clogged intake filter

3. Air leaks in piping (on

machine or in outside

system)

4. Broken inlet valves
