PLEASE NOTE:
This air compressor is not designed for continuous use.
The air compressor is oil free and therefore does not require any lubricants for it to run. (Please note: the
air tool itself, will still need to be lubricated. Please see your air tool instruction manual for the individual
tool requirement).
The air compressor should not be used in dusty environments. The warranty does not cover damage
caused by a blocked air filter.
It is important that the air compressor is positioned so that there is an
adequate airflow around the machine. The compressor should be situated
so that it has a 50cm of obstacle free space around its air receiver tank and
pump/motor unit.
Use extra lengths of hose rather than extension leads. Extension leads
which are too long, can cause the motor to overheat.
The air tool that you attach to the air compressor should have a preferred
PSI operating level. 2.5 bar is recommended for spraying and 6.0 is
recommended for air tools. To determine the correct working pressure and
air flow requirements for any piece of equipment, check the corresponding
manual. Be aware that the air flow figure stated on tools and accessories
refers to ‘Free Air Delivery’ and not the piston displacement of the
compressor.
STARTING UP
Make sure the on/off lever is in the off position (See fig. 5) before
connecting to the power supply. Connect the compressor to the power
supply.
Move the on/off lever to the on position, the compressor will start
(See fig. 3). Rotate the air outlet pressure regulator to the desired output
(See fig. 4) clockwise to increase the pressure or counter clockwise to
decrease the pressure and fix with locking ring.
Air is now drawn from the compressor. Check that the motor/pump unit
automatically starts, when the pressure falls by approximately 2 bar. If the
motor does not cut in and out, but runs continuously when using an air
appliance, the capacity of the compressor may be too small for the
equipment or tool.
Under normal use when the air compressor is running correctly you will hear
the following:
a) When the air compressor starts from no pressure within the tank, there is
a whistle of ‘leaking’ air from the pressure switch for about 20 seconds
(With the air outlet tap closed).
b) Whenever the motor stops there would be a quick sudden discharge of air
(This is the discharge of air from the head).
SAFETY BLOW OFF VALVE
The safety blow off valve (See fig. 7) is preset to release air if the tank exceeds its maximum pressure.
DO NOT
try to adjust the safety blow off valve pressure setting.
SHUTTING DOWN
Never stop the air compressor by unplugging it. Turn the on/off lever to the OFF position to switch the air
compressor off (See fig. 5). The on/off switch must always be used as this ensures that air is discharged
from the head. This makes the starting easier for the motor and prevents motor damage.

Ensure the air compressor is disconnected from the electrical supply and cannot operate accidentally when
servicing or cleaning. If a guard or safety feature needs to be removed during maintenance, be sure to
replace the guards or safety feature before resuming operation of the air compressor.
THE AIR RECEIVER TANK
Compressing air causes moisture, which is present in the air to condensate on the inside of the air
receiver tank. This water can damage your air tools and produce a poor finish when spraying paint. It also
damages the inside of the compressor and reduces its performance. It is important that the air receiver
tank is drained daily to increase the life span of the compressor and air tools. This is done by first opening
the air outlet pressure regulator to discharge the pressure. Place a container under the brass drain valve
on the underside of the air receiver tank and then unscrew the thumbscrew on the drain valve
anticlockwise (See fig. 6). Any water present in the air receiver tank should now flow out. As there is no
lubrication used in this compressor, the water is not polluted and can be disposed of in the sewer system.
THE AIR FILTER
The air filter must be cleaned or replaced monthly, or more frequently if the compressor is in regular use.
The air filter element can be accessed easily by unscrewing the wingnut holding the air filter cover
assembly and removing the filter element (see Figs.8 & 9). To clean a lightly soiled air filter, use soapy
water and leave to dry thoroughly.
SAFETY BLOW OFF VALVE
Occasionally check that the safety blow off valve is working properly by firstly cleaning any dirt or dust from
around the valve and then pull the metal ring to ensure the valve will release air (See fig. 7). The pressure
safety valve must be replaced if it cannot be pulled, or it leaks after releasing pressure.
Releasing the
safety blow off valve can be extremely loud. Make sure you wear hearing protection.
CLEANING
Clean the air compressor with a soft brush or a cloth moistened with a suitable biodegradable solvent. Do
not use inflammable liquids like petrol or alcohol, they are a fire risk and will also damage the paint finish
and plastic components.
CHECK FOR DAMAGED PARTS
Check for breakage of parts, mountings and other conditions that may affect the operation of the air
compressor. An authorised service and repair centre should
properly repair a damaged part, unless indicated otherwise in
this operator’s manual.
STORAGE
When not in use, run the air tool to relieve the air pressure in
the hose, then remove the tool and the air hose. The air
compressor should be stored in the dry, out of reach of children
and in a frost-free environment.
