GENERAL SAFETY INSTRUCTIONS
Before attempting to operate this compressor the following basic safety precautions should
always be taken to reduce the risk of fire, electric shock and personal injury. It is important to
read the instruction manual to understand the application, limitations and potential hazards
associated with any tool. They are designed for the safety of yourself and others, ensuring a
long and trouble free service life from your machine.
Work Area
Workbenches should be kept tidy because cluttered benches and work areas invite accidents.
Floors should be kept clean and free from rubbish. Special care should be taken if the floor is
slippery due to sawdust or wax.
Work Environment
Keep the work area well lit. Do not use compressor in areas where there is a risk of explosion
or fire from combustible materials, flammable liquids, e.g., paint, varnish, petrol etc or
flammable gases and dust of an explosive nature.
Guard Against Electric Shock
Do not expose your compressor to rain, or use in damp or wet locations.
Beware Children and Pets
Children and pets should be kept out of the work area.
Use the right tool
Select the right tool for the job. Do not use a tool for a job for which it was not designed.
Do not force a small tool to do the job of a heavy-duty tool.
Personal safety Clothing
Do not wear loose clothing, jewellery or anything that could get caught in moving machinery.
Hair
Long hair should be tied back or contained in a protective covering.
Eye Protection
Always use protective safety goggles or safety glasses.
Ear Protection
Ear protection is advised during periods of extended operation.
Footwear
Where there is a risk of heavy objects damaging feet or if there is a risk of slipping on wet or
slippery floors suitable non-slip safety footwear should be worn.
Secure the Work Piece
Wherever possible secure the work piece using clamps or a vice. It is safer than using your

--------------------------------------------------------------------------------------------------------------
hand and leaves both hands free to control the air tool.
Do Not Over-reach
Do not over-reach, keep proper footing and maintain your balance at all times.
Maintain Tools with Care
Keep cutting tools sharp and clean for better and safer performance. Follow the instructions
for lubricating and changing accessories. Check the tool power cord periodically and if
damaged have it replaced by an authorized service facility. Keep handles dry, clean and free
from oil and grease. Ensure that ventilation slots are kept clean and free from dust at all times.
Blocked ventilation slots can cause overheating and damage to the motor.
Stay Alert
Watch what you are doing, use common sense, and do not operate the air tool when you
are tired or have taken medication that causes drowsiness, consumed alcohol or drugs.
General Warnings for compressors
• Do not attempt to modify the compressor in any way.
• The use of any tools or accessory other than those designed for use with
compressed air could result in injury to the operator.
• The output pressure of the compressor should be adjusted to the design pressure
of the air tool or accessory being used.
• Always check that the output of the compressor does not exceed the maximum
pressure for any attached tool or accessory.
• Repairs should only be carried out by qualified persons using original spare parts.
Failure to do so may result in considerable danger to the user.
Breathable Air Warning
This compressor/pump is not equipped for, and should not be used to supply breathing
quality air for any application of air for human consumption.
Overload protection. This compressor is fitted with an overload protection device. In the
event that the motor becomes too hot, a thermal protection device will cut the mains supply
to the motor. When the motor temperature returns to normal the mains supply will be
restored automatically.
Extension Cords and Reels
In general, it is not recommended to use an extension lead. Alonger air line is recommended
as voltage drop on extension leads may lead to motor damage and will void warranty. If an
extension cord must be used, for lengths up to 5 metres, an approved 15 amp rated cord must
be used.
Do Not Abuse the Power Cord
Never yank or pull on the power cord to disconnect it from the mains supply socket. Never
carry or drag your compressor by its power cord. Keep the power cord away from heat, oil,
solvents and sharp edges. If the power cord becomes damaged have it replaced by an

--------------------------------------------------------------------------------------------------------------
authorized service facility.
Check Damaged Parts
Before using the compressor it should be carefully checked to determine that it will operate
properly and perform its intended function. Check for the correct alignment of moving parts
ensuring they do not bind. Check for broken or missing parts and have them replaced or
repaired at an authorized service centre. Check any other condition that may affect the
operation of the compressor. Aguard or any other part of the compressor that is damaged
should be properly repaired or replaced by an authorized service centre.
Disconnect Compressor
Ensure that the compressor is disconnected from the mains supply and the tank is empty
when not in use, before servicing, lubricating or making adjustments to air lines, and when
changing accessories such as blades, bits, nails and cutters on air tools.
Avoid Unintentional Starting
Ensure that the switch is in the OFF position before plugging the compressor into the
mains supply
Turning the compressor ON and OFF
Use the red knob on top of the pressure switch to turn the unit on and off. Pull the knob up
to turn the compressor on and push the knob in to turn it off. Turning the unit on and off from
the mains supply only will result in damage to the motor and void warranty as the pressure
switch has an additional function to purge the air trapped in the delivery pipe when the
motor is turned off. This minimises the load on the motor when it is next started.

1. Wheels and axle set
2. Rubber foot
3. Air Filter
•Fit the wheels to the unit using the axle
kit provided and insert the rubber stopper into the
spigot on the bottom of the tank.
•Fit the air filter to cylinder head of the compressor.
INITIAL STARTUP
•Ensure the unit is stable in a well-ventilated dry position.
•Ensure that the drain valve is closed and all air outlets are closed.
Connect the power lead to the mains.
•Start the compressor by pulling on the red knob.
Note: Output fittings may differ from those shown
Warning: Use the red knob to turn the unit on and off, not the mains switch. Turning the unit on
and off from the mains only will result in damage to the motor
OPERATION
The pressure in the tank is controlled by the action of the pressure switch located under the
pressure switch cover
When the set maximum pressure is reached the pressure switch activates and the motor is

turned off. The pressure will then decrease as the air is used until the set minimum is
reached after which the pressure switch turns the motor on again.
The operator of the compressor should be well aware that during use of the compressor the
motor will cycle (start and stop) under the influence of the rising or falling pressure in the tank
and the motor will start without any warning.
The maximum and minimum pressures are factory set and should not be altered.
You can utilize either the direct outlet and/or the regulated outlet.
The pressure of the regulated outlet can be changed by turning the control knob. Rotate
the knob clockwise to increase pressure and anti-clockwise to decrease
