reel always unwind the reel completely.
3. OPERATING INSTRUCTIONS
Preparation
Fig. B
Do not use textured wall paints or
coatings as this will block the nozzle.
To obtain the best results, it is important that you
prepare the surface to be sprayed and thin the
paint to the correct viscosity, before you operate
your spray gun. Always ensure that the surfaces
to be sprayed are free from dust, dirt and grease.
Make sure that you have masked the areas that

EN
6
should not be sprayed, using a good quality
masking tape. The paint or fluid to be sprayed
should be thoroughly mixed and free from lumps
or other particles. Many substances can be
sprayed with your spray gun, but always check
the manufacturers recommendations before
purchasing your paint.
Thinning
Always remember to disconnect from
the mains supply before filling the paint
container with sprayable material.
Most paints are supplied ready for brush
application and will need to be thinned before
they are suitable to be sprayed. Follow the
manufacturers advice on thinning the paint when
used with a spray gun. The viscosity cup will help
you to determine the correct viscosity of paint to
be used. To determine the correct viscosity, fill
the cup to the brim with the paint. Measure the
amount of time it takes for the cup to empty back
into the can.
The table below shows recommended times for
different types of material.
Plastic & latex paint 24 - 28 seconds
Water based paint 20 - 25 seconds
Primers 24 - 28 seconds
Varnishes 20 - 25 seconds
Oil based paints 18 - 22 seconds
Enamel paints 18 - 22 seconds
Aluminium paints 22 - 25 seconds
Car undersealing 25 - 35 seconds
Wood sealers 28 - 35 seconds
Wood preservatives No thinning required
Wood stains No thinning required
If the paint takes longer than the recommended
time to empty, then further thinning is required.
Mix in a small quantity of the appropriate thinner
and use the viscosity test until the correct
thickness is achieved. Some sprayable materials
contain particles and lumps. These materials
should be strained before filling the paint
container.
Spraying
Fig. C
Fill the paint container with the correctly thinned
and strained paint. Connect the spray gun to the
mains supply. Aim the spray gun at a piece of
scrap material and operate the trigger switch until
paint is spraying. Adjust the output control (2) until
the required volume of paint is spraying. Turn
the output control in a clockwise direction (B) to
reduce the flow and anti-clockwise (A) to increase
the flow. Adjustment of the output control will
affect the spray pattern. A poor spray pattern will
concentrate the paint in the centre of the spray and
give a blotchy finish. A good spray pattern will give
even distribution of paint throughout the pattern.
Spraying techniques
Fig. D
To obtain the best results, keep your spray gun
level and parallel to the surface at all times. Keep
the nozzle 25 - 30 cm from the surface and spray
evenly from side to side or up and down. Do not
spray at an angle as this will lead to paint runs on
the surface. Use smooth and even strokes. When
spraying large areas, use a criss-cross pattern as
shown.
Fig. E
Never start or stop the spray gun while it is aimed
at the surface to be sprayed. Evenly control the
speed of movement of the spray gun. A fast speed
of movement over the surface will give a thin coat
and a slow speed will give a heavy coat. Apply
one coat at a time. If a further coat is required,
make sure you observe the manu-facturers
drying time recommendations before applying a
second coat. When spraying small areas, keep
the output control on a low setting. This will avoid
using too much paint and prevent overspray.
Where possible, avoid stopping and starting when
spraying an object. This can lead to too much,
or not enough paint being applied. Do not tip the
spray gun to more than 45°.
Fitting and using the flexible nozzle
Fig. F
The flexible nozzle extension should be used to
spray flat or horizontal surfaces. It should also
be used in areas with limited access. To fit the
flexible nozzle, unscrew the basket nozzle and
attach the flexible nozzle in it‘s place. Replace the
basket nozzle on the end of the flexible nozzle
and tighten.

Cleaning and maintenance
Fig. G
Always remember to disconnect from
the mains supply before cleaning the
spray gun or paint container.
It is essential that the spray gun is cleaned
thoroughly after every use. Failure to clean it will
almost certainly result in blockages and it may
not operate when you next come to use it! The
guarantee does not cover cleaning a sprayer that
has not been properly cleaned by the user. The
following action must be taken after every use:
• Empty any remaining material from the
container.
• Clean the container thoroughly with the thinner
that was used.
• Pour some thinner into the container and spray
through the spray gun until only clean thinner
is coming out of the nozzle.
• Thoroughly clean the paint pick up pipe and
filter with thinner.
• Clean the basket and nozzle and remove any
other debris or paint that remains.
• Turn the spray gun upside down and apply a
few drops of light oil to the two apertures (F).
This will lubricate the piston and cylinder.

GENERAL SAFETY INSTRUCTIONS
Warning!
Read all instructions. Failure to follow all instructions listed
below may result in electric shock, fire and/or serious injury.
The term “power tool” in all of the warnings listed below
refers to your mains operated (corded) power tool or battery
operated (cordless) power tool. Save these instructions.
1) Work area
a. Keep work area clean and well lit. Cluttered and dark
areas invite accidents.
b. Do not operate power tools in explosive atmospheres,
such as in the presence of flammable liquids, gasses
or dust. Power tools create sparks which may ignite the
dust of fumes.
c. Keep children and bystanders away while operating a
power tool. Distractions can cause you to lose control.
2) Electrical safety
a. Power tool plugs must match the outlet. Never modify
the plug in any way. Do not use any adapter plugs which
earthed (grounded) power tools. Unmodified plugs and
matching outlets will reduce risk of electric shock.
b. Avoid body contact with earthed or grounded surfaces
such as pipes, radiators, ranges and refrigerators. There
is an increased risk of electric shock if your body is
earthed or grounded.
c. Do not expose power tools to rain or wet conditions.
Water entering a power tool will increase the risk of
electric shock.
d. Do not abuse the cord. Never use the cord for carrying,
pulling or unplugging the power tool. Keep cord away
from heat, oil, sharp edges or moving parts. Damaged or
entangled cords increase the risk of electric shock.
e. When operating a power tool outdoors, use an extension
cord suitable for outdoor use. Use of a cord suitable for
outdoor use reduces the risk of electric shock. Always
use tool in conjunction with a residual circuit breaker
device.
3) Personal safety
a. Stay alert, watch what you are doing and use common
sense when operating a power tool. Do not use a power
tool while you are tired or under the influence of drugs,
alcohol or medication. A moment of inattention while
operating power tools may result in serious personal
injury.
b. Use safety equipment.Always wear eye protection.
Safety equipment such as dust mask, non-skid
safety shoes, hard hat, or hearing protection used for
appropriate conditions will reduce personal injuries.
c. Avoid accidental starting. Ensure the switch is in the off
position before plugging in. Carrying power tools with
your finger on the switch or plugging in power tools that
have the switch on invites accidents.
d. Remove any adjusting key or wrench before turning
the power tool on. A wrench or a key left attached to a
rotating part of the power tool may result in personal
injury.
e. Do not overreach. Keep proper footing and balance at
all times. This enables better control of the power tool in
unexpected situations.
f. Dress properly. Do not wear loose clothing or jewellery.
Keep your hair, clothing and gloves away from moving
parts. Loose clothes, jewellery or long hair can be
caught in moving parts.
g. If devices are provided for the connection of dust
extraction and collection facilities, ensure these are
connected and properly used. Use of these devices can
reduce dust related hazards.
h. Use clamps or a vice to hold work. It’s safer than using
your hand and it frees both hands to operate tool.
4) Power tool use and care
a. Do not force the power tool. Use the correct power
tool for your application. The correct power tool will
do the job better and safer at the rate for which it was
designed.
b. Do not use the power tool if the switch does not turn it
on and off. Any power tool that cannot be controlled with
the switch is dangerous and must be repaired.
c. Disconnect the plug from the power source before
making any adjustments, changing accessories, or
storing power tools. Such preventive safety measures
reduce the risk of starting the power tool accidentally.
d. Store idle power tools out of the reach of children and
do not allow persons unfamiliar with the power tool or
these instructions to operate the power tool. Power tools
are dangerous in the hands of untrained users.
e. Maintain power tools. Check for misalignment or binding
of moving parts, breakage of parts and any other
condition that may affect the power tools operation.
If damaged, have the power tool repaired before use.
Many accidents are caused by poorly maintained power
tools.
f. Keep cutting tools sharp and clean. Properly maintained
cutting tools with sharp cutting edges are less likely to
bind and are easier to control.
g. Use the power tool, accessories and tool bits etc., in
accordance with these instructions and in the manner
intended for the particular type of power tool, taking
into account the working conditions and the work to be
performed. Use of the power tool for operations different
from intended could result in hazardous situation.
