GENERAL SAFETY INSTRUCTIONS
Before attempting to operate this compressor the following basic safety precautions should
always be taken to reduce the risk of fire 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.
SAFE OPERATION
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 flam-
mable gases and dust of an explosive nature.
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
All ways 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.

Air Compressor
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 authorised 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 operate the compressor without the belt guard being correctly fitted.
Do not attempt to modify the compressor in any way.
The use of any tool 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. Fail-
ure to do so may result in considerable danger to the user.
Breathable Air Warning
This compressor/pump is not equipped and should not be used to supply breathing quality air for
any application of air for human consumption.
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
authorised service centre. Check any other condition that may affect the operation of the compressor. A guard or any other part of the compressor that is damaged should be properly repaired or replaced by an authorised service centre.

Air Compressor
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 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.

over 10 deg C and use SAE10 below 10 deg C.
Oil Warning : Check the oil level before using the compressor.
Check the oil level. If necessary add oil until it
reaches the red mark on the sight glass. Do Not over fill.

Air Compressor
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 decreases as the air is used until the set minimum is
reached after which the pressure switch turns the motor to 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.
.
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 minimizes the load on the motor when it is next started.
When storing or finishing with the compressor
Check:
The on/off button is in the off position
The mains cord is disconnected from the mains supply.
The all the air is discharged from the tank
(empty the tank)
