Safety Precautions
Good Working Practices/Safety
The following suggestions will enable you to observe good working practices, keep yourself and fellow workers
safe and maintain your tools and equipment in good working order.
WARNING!! KEEP TOOLS AND EQUIPMENT OUT OF THE REACH OF YOUNG
CHILDREN
Air Powered Tools
1. Always perform pre-operation checks before
starting up the compressor.
2. Never leave inflammable objects or materials near
to the compressor.
3. Always check oil level before using the
compressor.
4. The cylinder, cylinder head and delivery pipe
become hot during use. Do not touch these items
while the compressor is running. Allow to cool
thoroughly after shut-down before handling.
5. Do not operate above the maximum working
pressure of 115 psi (7.8 bar).
6. Avoid using the compressor with an extension
cable; this may reduce the supply voltage and make
the motor overheat.
7. Switch the compressor on and off by using the
pressure switch knob (Fig 3); only switch off at the
mains in case of emergency.
8. Drain water from tank every day.
9. If the compressor shuts down through overload or
overheating check the reason for the shut-down
before re-starting.
10. Do not adjust the tank pressure switch without
reference to Axminster Power Tool Service
Department.
11. Do not remove parts from the compressor whilst
it is running.
12. Do not operate the compressor with protective
covers removed or damaged.
13. When spray painting always work in a well
ventilated area and never close to open flames.
14. Never direct a jet of compressed air towards
people or animals. Keep children and animals away
from the compressor.
15. Do not use on an inclined surface.
16. Only use in ambient temperatures between –40˚C
and +70˚C.
17. Only operate on 230 volt supply and with
maximum fuse rating of 13 amps.

Axminster Power Tool Centre’s Customer Services
Department. Fit the wheels, (see instructions below).
Remove the plastic transport plug from the crankcase
and fill with good quality compressor oil, (see our
catalogue) until the level is in line with the circle
marked on the oil level indicator. (See page 05) Locate
the oil filler plug (G) and screw it into the crankcase.

Operating Instructions
08
The outlet air pressure can be regulated by rotating the
regulator knob clockwise to increase the pressure and
anticlockwise to reduce it. Do not leave the regulator
set at maximum setting unnecessarily; reduce the
setting by about two turns after finishing and then
re-set to the required pressure when starting work
again.
Connect the compressor to the mains supply and
switch on by pulling the on/off knob upwards. (See figs
3-4) Check that the compressor pressurises the tank
and shuts off when the maximum tank pressure is
reached.
The compressor is automatic in operation; the pressure
switch shuts the motor off when the maximum tank
pressure is reached and re-starts it when the pressure
drops below a pre-set level. The cut-in and cut-out
pressures are factory set and should not need to be
altered.
NOTE: It is advisable to fully drain the air from the
tank if the compressor is left unused overnight, this
will prevent the build-up of water in the tank.
Do not use dirty or non detergent oil.
Do not operate compressor in an ambient
temperature above 40˚C.
Do not operate in a badly ventilated area.
Keep the air filter clean.

Fig 5 Fig 6
Fig 7 Fig 8
Daily:
Drain water from tank. (See fig 5)
Weekly:
Check oil level and top-up if necessary. (See fig 6)
Monthly:
Un-clip and remove the air inlet filter outer casing and
clean the filter element with the following: (See fig 7)
(a) Compressed air
(b) Wash in soapy water and left to dry.
Do not use the compressor without the air filter fitted.
Six Monthly:
Change the oil. With the oil still warm remove the oil
filler plug, place a suitable container under the drain
plug and drain the oil right out. (See fig 8) Replace drain
plug and refill to the level mark on the sight glass.
Yearly:
(a) Replace the air filter element.
(b) Check and clean the air intake and delivery valves.
(c) Check the non return - valve and replace the seal
between the crankcase and cover if necessary.
When components are removed for servicing, take the
opportunity to fit new seals.
Note: (b) and (c) should be undertaken by a competent
service engineer.
