This air tool operates at a max. pressure of 3bar (43psi).
The compressed air system must be controlled by a
combination pressure regulator and moisture lter;
this will ensure a constant supply of dry air at all times,
provided it is properly maintained.
Important: Always check the machine operating
pressure before use.
Water in the compressor tank may cause considerable
corrosion to air tools; the compressor should be drained
Fig. 1
7.2 Cleaning the Product and Accessories
Before First Use
Before rst use, the spray gun must be cleaned
thoroughly to remove any oil, grease and the protective
lm applied before shipment.
1. Disassemble the spray gun and immerse all parts and
accessories in spray gun cleaning uid.
2. Soak the parts for a few minutes.
3. Allow the parts to dry and then wipe them clean with
a damp cloth.
4. Assemble the spray gun (see 7.3) and half-ll the paint cup (8) with thinners.Important: DO NOT connect the spray gun to the
regulator or air line at this time.
5. Squeeze the trigger (12) to ush the thinners through
the spray gun until the paint cup is empty.
6. Immerse and soak the assembled spray gun in the
cleaning uid for a few more minutes.
7. Allow the parts to dry and wipe them clean.
daily to avoid excessive water in the air supply. Dirty or
wet air can signicantly shorten the lifespan of the product.
When using an air tool with a hose over 25ft long,
Draper Tools recommends increasing the bore of the
hose to the next largest available size (i.e. increase 3/8”
to 1/2”). This will ensure adequate pressure and volume
of air to power the tool.
CAUTION! DO NOT lubricate the air line when
using paint spray guns. Ensure that any oil device
has been removed and any residual oil is purged
from the system before connecting the spray gun.
7.3 Assembly, Filling and Connection
Important: Draper Tools recommends using a 1/4" BSP
thread whip hose (Stock No. 54438) to connect the spray
gun to an air line in order to reduce vibration.
1. Insert the paint lter (C) fully into the spray gun paint
inlet (9) with the needle pointing downwards.

5. Screw the 1/4" air line coupling (D) onto the spray gun
air inlet.
Important: If using a whip hose, attach a parallel
union nut (Stock No. 25823) instead of the air line
coupling. Wrap a length of PTFE tape around the
whip hose outlet thread and attach it to the parallel
union nut.
(D)

Important: ALWAYS ensure that the paint is mixed
and thinned to the manufacturer’s recommendations.
8. Pressurise the air line when you are ready to begin.

8. Operating Instructions
Important: Before using this product, read and
understand all the safety instructions listed in this
manual. DO NOT make any adjustments to the spray gun
while the trigger is depressed.
8.1 The Air Control Dial
(2)
Fig. 7
The air pressure can be ne-tuned by adjusting the air
control dial (2) on the spray gun. This is used to make
minor adjustments to the air ow after the required air
pressure has been set by the air line regulator.
• To increase the airow: Rotate the dial clockwise.
• To decrease the airow: Rotate the dial anticlockwise.
Important: The air control dial should typically remain in
the fully open position to allow the full ow of air into the
spray gun, but it may be used to make minor adjustments
for specic operations. The dial will click when it has
been wound to its fully open position.
The uid control dial (4) adjusts the amount of paint that
is released into the air ow and the density of the spray
when the trigger is fully depressed:
• To increase the paint quantity and density:
Rotate the nozzle regulator anticlockwise.
− The paint quantity should be increased when the
spray gun is positioned further from the surface or
when the paint mixture has a higher viscosity.
• To decrease the paint quantity and density:
Rotate the nozzle regulator clockwise.
− The paint quantity should be decreased when the
spray gun is positioned closer to the surface or
when the paint mixture has a lower viscosity.
8.3 The Spray Control Dial
(10)
Fig. 9
The spray control dial (10) adjusts the shape of the paint
jet released from the nozzle. The spray control dial can be
rotated 360°.
8.2 The Fluid Control Dial
Fig. 8
(4)
• Fuller, atter pattern: Rotate the dial clockwise.
• Narrower, rounder pattern: Rotate the dial
anticlockwise.
8.4 The Air Cap
The air cap (1) has three types of opening that aect the
pattern of the uid spray:
• A hole for the nozzle head from which the uid is
dispersed (13).
• Atomising air holes (14) that break the uid into a
ne spray.
• Air horn holes (15) that shape the spray pattern
as required.

(14)
(13)
(1)
Fig. 10
Once the spray pattern has been set using the control
dial, rotate the air cap to change the orientation of
the jet.
Important: ALWAYS ensure that the air cap remains
tightly secured after adjusting its orientation.
8.5 The Trigger
• Keep the spray gun 6–12" away from the surface
during operation.
• Start moving the spray gun BEFORE squeezing
the trigger to prevent a build-up of paint at the
starting point.
• Move the spray gun with a smooth motion, keeping it
perpendicular to and at a constant distance from the
surface at all times.
• DO NOT rock or pivot the spray gun as this will deliver
uneven coverage of the surface.
• DO NOT hold the spray gun in a static position
while the trigger is depressed as this will deliver
uneven coverage.
• Slightly overlap the movements of the spray gun
to ensure an even distribution at the edges of
each stroke.
• Use a piece of scrap material at the edges of the area
to prevent overspray and protect other surfaces.
• Alter the speed of the movement, the distance from
the surface and the uid control dial setting to adjust
the thickness of the paint applied to the surface.
• Release the trigger BEFORE completing the spray gun
movement at the end of the nal stroke to prevent a
build-up of paint at the nishing point.
(12)
Fig. 11
Paint is released from the spray gun by squeezing the
trigger (12):
1. First, squeeze the trigger until resistance is met;
this opens the air valve.
2. Squeeze the trigger the rest of the way to draw the
uid pin back and release paint from the nozzle.
Important: Draper Tools recommends that you test
the spray output on an area of scrap material before
working on the genuine surface. Adjust the control
dials to produce an even ow in the desired pattern.
ALWAY S release the trigger before making any
adjustment to the spray gun.
