For a professional looking finish paint must be thinned. If the manufacturers
recommendations on thinning are not available, the following can be used as a
The first requirement for a good resultant finish is the proper handling of the gun.
The gun should be held perpendicular to the surface being covered and moved
parallel to it. The stroke should be started before the trigger is pulled and the
trigger should be released before the stroke is ended. This gives accurate control
of the gun and material.
The distance between gun and surface should be 6 to 12 inches depending on
material and atomizing pressure. The material deposited should always be even
and wet. Lap each stroke over the preceding stroke to obtain a uniform finish.
NOTE: To reduce overspray and obtain maximum efficiency, always spray

SAFETY PRECAUTIONS.
Before using your compressor it is in your own interest to read and pay attention to
the following safety rules
1. COMPRESSED AIR IS DANGEROUS - Never direct a jet of air at people or animals.
2. Do not operate your air compressor with any guards removed.
3. Electrical or mechanical repairs should only be carried out by a qualified
4. Before attempting any repair, ensure that pressure is expelled from the air

6. Close the air outlet tap and connect one end of a suitable air hose to the
compressor and the other end to the equipment to be used. If spraying, DO
NOT have the paint pot attached at this stage.
5. Before connecting your airline to the compressor open and close the outlet tap
will begin to register on the pressure gauge (F). When the compressor reaches its
maximum working pressure, the motor will automatically cut out, and will restart
when the pressure has fallen by approximately 20 psi. This automatic STOP/ START
process will continue, as necessary, to maintain pressure in the receiver.

and leave it running with the air outlet tap fully open for a short period to permit
good distribution of lubricating oil. When closing the tap, pressure in the air receiver

the pressure adjuster knob (C) anticlockwise until the gauge (E) registers
a pressure well below that which you require, then release the trigger, or
operating mechanism of the air tool, in order to stop air from exhausting.
Screw in the pressure adjuster (C) clockwise until the needle on the
pressure gauge (E) registers the pressure you require.
When the required pressure is reached, push the pressure adjuster knob
down again in order to hold the setting.

When components are removed for servicing ALWAYS take the opportunity to fit new seals.
In the event of air leaks, follow the procedure below:

4. Any leaks will show through the formation of air bubbles.
Check and clean the intake and delivery valves.
NOTE:
Replace the air intake element.
Clean all the cooling fins to ensure efficient cooling and a long working life.
• IMPORTANT: Never operate the compressor without the air intake filter fitted.
This procedure should be carried out more frequently if the compressor is used in
dusty conditions.
• Remember that a dirty filter prevents adequate aspiration and adversely
Reassemble in reverse order, taking care not to overtighten the filter plate retaining
