PARTS

1. Air cap
2. Union nut
3. Sprayer
4. Trigger
5. Regulator screw

ASSEMBLY

• Attach the hose to the air pump, ensuring the nodule on the side of the
air pump housing is aligned with the recess in the hose fitting and twist
clockwise to secure.
• Push or twist the spray head onto the other end of the hose, ensuring it is
fitted securely.
• Attach the shoulder strap to either end of the paint gun, ensuring the
clips are securely fastened.

BEFORE USE

• Check all parts for damage before first use.

OPERATION

Preparing Materials

• The paint gun can be used to spray paint, lacquer or varnish.
• First measure the viscosity of the paint by dipping the funnel into the
paint until it is full of paint and timing how long it takes to drain out of
the funnel, see recommended viscosity table below:
Substance
Water-based paint, emulsion
Enamel paint, water-based or solvent-based
coloured lacquer
Primers
Varnish, wood coating, oil, disinfectants,
colouring agent

45-50 seconds
Do not dilute
Note: The above table should be used as an approximate guide only. Always
follow the manufacturers' instructions supplied with the substance.
• The paint gun can be used with substances with a funnel drain time of
25-50 seconds. Some paints may require diluting slightly until they reach
this viscosity.
• Initially dilute the paint with a thinner by 10% and stir well to mix.
• If the diluted paint still does not have the required viscosity, dilute by a further
5% and repeat until the desired viscosity is reached.

Spraying

• Depending on the angle at which
you are spraying, and whether the
surface is horizontal or vertical,
adjust the suction tube to the
desired position to ensure it is
pointing towards the section of
the container that is lowest
during use. See fig. 2
• Fill the container with paint.
• Ensure that all surfaces that are
not to be sprayed, e.g. screws,
screw threads, skirting boards,
wall sockets, etc. are covered.
• Ensure the surface to be sprayed
is completely clean and even
before spraying. Pre-treat the
surface before spraying if necessary.
• Always test on a piece of cardboard or an inconspicuous area
before proceeding.
• Always move the arm and not the wrist when spraying to ensure an even
distance is kept from the target area, typically between 5-15cm.
• Move the paint gun evenly to ensure an even coating.

Spray Settings

There are 3 spray settings, see fig. 3:
1. Vertical flat jet, used for horizontal
surfaces.
2. Horizontal flat jet, used for vertical
surfaces.
3. Circular jet, used for edges, corners and
hard to reach places.
To adjust the spray setting, turn the screw
anti-clockwise approximately two
rotations. Twist the air cap to the desired
setting and tighten the screw. See fig.4
To adjust the

volume of paint
sprayed, adjust the
regulator screw on
the trigger handle.
Turn anti-clockwise
to reduce the
volume sprayed
and clockwise to
increase. See fig.5
