15. SPRAY GUN OPERATION
15.1.
For best results, the gun should be held perpendicular to the surface being sprayed and moved parallel to it. Start the stroke before
squeezing the trigger and release the trigger before finishing the stroke. This will enable accurate control of the gun and material
refer to fig’s 9 & 10 below.
15.2.
S
pray from a distance of about 6 to 10 inches (150 to 250mm) depending on the material and the atomizing pressure. The material
deposited should always be even and wet. Each stroke must overlap the preceding stroke to obtain a uniform finish. To reduce
over-spray and obtain maximum efficiency, spray with the lowest possible atomizing air pressure.
15.3.
C
ontrolling the fan spray and the fluid.
a)
Use the needle (paint) adjustment knob (fig.11.2) to adjust the amount of paint flow.
b)
The atomizing air flow is controlled by the control knob (fig.11.1).
c)
The volume of air input is controlled by the adjustment knob (fig.11.3).
d)
As width of spray is increased more material must pass through the gun to obtain the same coverage on the increased
area.
e)
Turn the air nozzle (fig.11.4) to achieve a horizontal or vertical fan spray. Lock the nozzle with retaining ring (fig.11.5).
The spray pattern of the gun is variable from round to flat with all patterns in between. In normal operation, the wings on
the nozzle are horizontal (fig.12). This provides a vertical fan-shaped pattern which gives maximum, uniform and even
coverage when moving the gun back and forth, parallel to the work surface (fig.13).
16. SPRAYGUN MAINTENANCE
fOR OPTIMUM PERfORMANCE IT IS VERY IMPORTANT TO ENSURE THE SPRAY GUN IS CORRECTLY CLEANED AfTER
EACH USE.
disconnect from the air supply before attempting any cleaning or maintenance.
16.1.
CLEANING THE GUN
16.1.1.
Flush the gun through with clean solvent.
16.1.2. U
se a bristle brush and solvent to wash off accumulated paint.
16.1.3.
C
lean the air nozzle using a brush. Blow clean with air. Handle all nozzles carefully and do not make any alterations in the gun.
16.1.4. W
ipe the outside of the gun with a dampened solvent rag.
16.1.5.
I
f there is a need to probe the holes in the nozzles, ensure a tool that is softer than brass is utilised, under no circumstances use a
metal tool, as the slightest amount of damage will adversely affect the spray pattern.
16.1.6.
A
djust the fluid needle valve so that when the gun is triggered, air flow occurs before fluid flow.
16.2.
MAINTENANCE
16.2.1.
Take care when re-assembling. Screw parts hand tight to avoid cross-threading. If a part cannot easily be turned by hand, check
that it is the correct part, or unscrew it, realign and retry.
DO NOT
use excessive force when re-assembling.
16.2.2. When changing the nozzle size, ensure the complete nozzle set is fitted. This consists of air cap, fluid nozzle and paint needle.
Insert the fluid nozzle before paint needle.
17. TYRE INfLATOR OPERATION
17.1.
ATTACH ADAPTOR TO VALVE
Push and hold the connector onto the tyre valve, squeeze the thumb clip on the connector, push the connector onto the tyre valve and
release the clip.
The connector will now be locked in place.
17.2.
TO INfLATE
Momentarily depress the operation lever fully, then release to display tyre pressure. When reading the pressure, hold the gauge “flat”
with respect to the eye to minimise error.
Fully depress operation lever for an appropriate period. Avoid over inflation, release lever frequently to check the pressure.
