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 importantto
read the instruction manual to understand the application, limitations and potential hazards
associated with anytool. 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 kepttidy 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.
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 righttoolfor 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
slipperyfloors suitable non-slip safety footwear should be worn.

4
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 handsfree to controlthe 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 cleanfor better and safer performance. Follow the instructionsfor
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 venti-
lation slots can cause overheating and damage tothe 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.
FOR ADDITIONAL PROTECTION FROM ELECTRIC SHOCK
It is recommended that this tool be used in conjunction with a residual current device (RCD)
with a rated residual current of 30mA or less.
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 thatthe 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.
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 tothe mo-
tor. When the motor temperature returns to normal the mains supply will be restored automati-
cally.

5
Extension Cords and Reels
In general, it is not recommended to use an extension lead. A longer air line is recommended as
voltage drop on extension leads may lead to motor damage and will void warranty. If a exten-
sion cord must be used,for lengths up to 5 metres, an approved 15amp 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 authorised service
facility.
Check Damaged Parts
Before using the compressor it should be carefully checked to determine that it will operate prop-
erly and perform its intendedfunction. 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 com-
pressor. A guard or any other part of the compressor that is damaged should be properly re-
paired or replaced by an authorised 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 when changing acces-
sories 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 toturn it off. Turning the unit on and off from the
mains supply only will result in damagetothe motor and void warranty as the pressure switch
has an additional function to purgethe air trapped in the delivery pipe when the motor is turned
off. This minimises the load on the motor when it is next started.

Assembly
This air compressor requires some minor assemble before it can be used.
Locate the accessory pack. It should contain :
1. Wheels and axle set
2. Rubber stopper
3. Air Filter
4. Oil Breather plug
5. A bottle of oil
• 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.
• Locate the plastic dust plug in the oil filler hole and remove it
to expose the oil filler hole.

Oil Warning : This unit is shipped without oil in the compressor pump. Oil must be
added to the unit prior to operating.
Oil
• Using the oil provided carefullyfill the crank case until the oil reaches the red mark on
the sight glass
2HP
• Check thatthe small hole in the top of the breather pipe
is clear andthen insert it into the oil filler hole.
NOTE: The oil must be changed after the first 10 hrs of operation then every 20 hrsthereafter .
Recommend compressor oil: Use SAE30 for temperatures over 10
and use SAE10 below 10 .
INITIAL STARTUP
• Ensure the unit is stable in a well-ventilated dry posi-
tion.
• Ensure that drain the valve is closed and air outlets
are closed.
Connect the power lead to the mains.
• Startthe compressor by pulling on the red knob.
• Check for air leaks
Warning: Use the red knob toturnthe 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 reachedthe 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 awarethat 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 utilise eitherthe 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
