TROUBLESHOOTING
POSSIBLE CAUSE
Air leaks at connections.
The non-return valve seal
is defective.
The overload cut-out has
operated because of the
motor overheating or the
voltage supply to the
motor is low.
The motor windings have
burnt out.
The capacitor has burnt
out.
The air compressors head
gasket has broken or the
valve is faulty.
The air compressors head
gasket has broken or the
valve is faulty.
The pressure switch needs
adjusting.
The tank is full of water
due to condensation.
SOLUTION
et the compressor build pressure in the tank;
to the maximum pressure if possible. Switch
off. Brush soapy water on air connections and
look carefully for air bubbles. Tighten leaking
connections. If the fault persists, contact your
local Kobe agent.
et the air in the tank flow out until all the
pressure is released. Then remove the non
return-valve plug and clean the valve seat. If
necessary replace the ‘O’ ring seal and then re-
mount all the components (See fig. 10).
Check that the mains voltage corresponds to
the specifications. An extension cable, which is
too thin and too long, can cause the motor to
overheat. eave the air compressor to cool
down as the thermal cut out has operated. Use
heavy duty extension cables. Ensure that the
compressor is plugged into a socket as near to
the consumer unit/fuse box as possible.
Contact your local Kobe agent.
Replace the starter capacitor.
Stop the air compressor and contact your local
Kobe agent.
Stop the air compressor and contact your local
Kobe agent.
Stop the air compressor and contact your local
Kobe agent.
Connect an air hose with a low gun fitted and
release the pressure. Open the drain valve
underneath the air compressor and release the
water within the tank.
FAULT
Pressure drops.
The pressure switch valve
leaks when the
compressor is idle.
The compressor has
stopped, does not start or
starts slowly
The compressor has
stopped, does not start.
The motor does not start
and makes a humming
noise.
The air compressor is
noisy with metallic clangs.
The air compressor does
not reach the maximum
pressure.
The air compressor
doesn’t seem to provide
as much air as it did when
new and the air
compressor cuts off within
a much shorter time
period.
Repairs must be performed in a dirt-free environment by a qualified person who is familiar
with this type of equipment. Make sure the air receiver tank is de-pressurised before
carrying out any repairs.

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. ake 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 DA AGED 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.
