they are connected and properly used. The use of
these devices can reduce dust related hazards.
CONNECTIONS AND AIR TYPE.
Quick connections should be used for connections
with the compressed air system and male non-wa-
tertight sleeve must be installed in the paint spray
gun so that no air is compressed after the discon-
nection. Never use oxygen, combustible gases or
any other bottled gases. Never use oxygen tanks,
fuel gas, etc. as a power source for the paint spray
gun. Use of these gases or other bottled gases is
dangerous, because the paint spray gun could ex-
plode. Use only clean, dry and regulated compres-
sed air.
MAXIMUM PRESSURE.
The paint spray gun should be connected to a sou-
rce of compressed air if the pressure does not ex-
ceeded more than 10% the maximum allowable
pressure of the paint spray gun; in case of higher
pressures a pressure reducing valve should be
installed, including a valve-up downstream in the
supply of compressed air.
DO NOT POINT THE PAINT SPRAY GUN.
Never aim it at yourself or others, being the paint
spray gun loaded or not. Never play with the paint
spray gun, use the paint spray gun as a professio-
nal tool.
STORE PNEUMATIC TOOLS.
Store pneumatic tools out of reach of children and
not allow the handling of pneumatic tools to people
unfamiliar with the tools or these instructions. Pneu-
matic tools are dangerous in the hands of untrained
users.
MAINTENANCE.
Check moving parts for misalignment or binding,
there are no broken parts or other conditions that
may a󰀨ect the operation of pneumatic tools. Pneu-
matic tools are repaired before use when they are
damaged. Many accidents are caused by poorly
maintained pneumatic tools. Use pneumatic tools,
accessories and tool tips, etc. according to these
instructions and in the manner provided for the par-
ticular type of pneumatic tool, taking into account
the conditions work and work to develop. The use
of the pneumatic tool for applications other than
those intended could result in a dangerous situa-
tion. Please check your pneumatic tool serviced by
a Werku® o󰀩cial repair service using only identical
replacement parts. This will ensure the safety of the
pneumatic tool is maintained.
CHECK CONDITION.
Make sure that all the screws in the paint spray gun
are perfectly tightened. In cold climates or when
the paint spray gun has not been used for a period,
allow the paint spray gun to warm up by leaving it to
run empty for a few minutes, to ensure that all inter-
nal components are perfectly lubricated. Make sure
that the possible installed accessories are perfectly
tted in place.
BEFORE STARTING WORK.
Make sure that the suction paint spray gun is rmly
supported before using. Check that no one is stan-
ding beneath you when using the suction paint spray
gun in high areas. Keep your hands away from all
moving parts of the suction paint spray gun.
DURING THE OPERATION.
Do not leave the suction paint spray gun operating
without having it rmly xed. Only turn it on when
you are sure you have full control over it. Do not
point the suction paint spray gun at anyone while in
use. When operating the suction paint spray gun will
produce vibrations. The screws may gradually come
loose, and possibly cause faults or accidents. Keep
your hands away from all moving parts of the suction
paint spray gun.
AT FINISH WORKING.
Do not touch the possible accessories installed in
the suction paint spray gun after use. It may be hot
and cause burns. Some materials worked with may
contain chemicals or toxic components. Avoid in-
haling these substances or allowing them to come
into contact with your skin. Use PPE designed to
prevent and protect against incidents of this kind.

USE INSTRUCTIONS.
Before putting the paint spray gun into operation, it is
advisable to read all the indicated instructions. Likewi-
se, accident prevention rules, regulations and guideli-
nes for work centres and current laws and restrictions
must be taken into account. The paint spray gun must
be used only by personnel who have been trained
adequately in their handling, and only for the uses for
which it has been designed.
COMPRESSOR.
Do not use another power source than an air com-
pressor. The paint spray gun is designed for using
with an air compressor, never use carbon dioxide,
oxygen or any other bottle gas.
AIR SUPPLY AND CONNECTION SYSTEM.
For a correct installation follow the steps shown in
the diagram (13).
OPERATION.
The compressed air enters through the air in-
let, which is screwed on to the grip of the paint
spray gun (1). By pressing the trigger, the air valve
opens to the rst pressure point (initial air control)
(2). Pressing down further on the trigger, a jet of
paint squirts through the uid outlet (3). The paint
runs through by gravity without any pressure, and
is pulverised by the compressed air (4).
NOZZLE REGULATOR.
The nozzle regulator adjusts the amount of paint
that is pulverised (5). For more paint, twist the
nozzle regulator to the left (6). For less paint, twist
the nozzle regulator control to the right (7).
SPRAY CONTROL.
The spray control adjusts the width of the spray
produced by the paint spray gun. Twist the spray
control to the right for wider coverage, or to the left
for a narrower jet (8, 9). The spray control may be
turned through a total of 360º, and when loosened
the paint jet may be directed as required (10).
START-UP.
Fully close the nozzle regulator (5). Connect the
paint spray gun to the compressed air supply (1).
Press the trigger, rst checking air output and then
paint output (2). The paint spray gun must be ad-
justed depending on the type of paint used. Open
the uid outlet control until obtaining an even
spray.
SPRAYING TECHNIQUES.
For best results keep the paint spray gun level and
parallel to the surface being painted at all times. Hold
the paint spray gun 25-30 cm from the working sur-
face and spray evenly from left to right and up and
down with slow movements. Do not spray at an an-
gle, as this will cause the paint to form droplets on the
surface. When spraying large areas, use a correct
working plan (11). Spray moving the arms and not
the wrist. Control the speed of the paint spray gun
to achieve a smooth, regular movement. Moving too
quickly will cause the paint layer to be too thin. Si-
milarly, moving too slowly will cause the paint layer

English

to be too thick. Apply the coats of paint one by one,
leaving them to dry for the times indicated by the ma-
nufacturer.
NEEDLE, NOZZLE AND REGULATOR CHANGE.
Unscrew and remove the spray direction control (A).
Unscrew and remove the nozzle regulator (E). Subse-
quently, pull back the uid-ow needle until it is comple-
tely removed. Using the wrench provided, unscrew and
remove the uid-ow nozzle from the head, then screw
in the new uid-ow nozzle. Insert the new uid-ow
needle. Then screw in the nozzle regulator (E). Screw
in the new spray direction control (A).
IMPORTANT.
Using products containing halogenated hydrocar-
bons may cause chemical reactions that lead to
explosions. When using solvents and detergents
containing halogenated hydrocarbons, such as
1,1,1-trichloroethane and methylene chlorate,
chemical reactions may occur in the tank, gun and
galvanised parts (when 1, 1, 1-trichloroethane co-
mes into contact with water droplets it produces
chlorohydric acid). We recommend using products
that do not contain these elements. Before using
the paint spray gun and its accessories, these
must be cleaned with cleaning solvent, to remove
the protective lm applied before packing. Acid or
alkaline products must not be used to clean the
paint spray gun.
MAINTENANCE.
Drain all condensation from the air compressed
tanks and hoses (12). To do so, open the decom-
pression taps and other drainage valves in the
tanks.
IMPORTANT.
The paint spray gun has been designed for a long
working life with minimum maintenance. Optimum
use depends on correct care of the paint spray gun
and regular cleaning. The paint spray gun may be
cleaned e󰀨ectively using compressed air. If com-
pressed air is not available, use a brush to remo-
ve dust from the paint spray gun. Cetain cleaning
agents and solvents damage plastic parts, among
them are gasoline, carbon tetrachloride, chlorina-
ted cleaning solvents, ammonia and household
cleaners containing ammonia. Do not use any of
these to clean the paint spray gun.
