2. IMPORTANT SAFETY INFORMATION
General Safety Instructions
WARNING Read all safety warnings and all instructions. Failure to follow
the warnings and instructions may result in electric shock, fire and/or serious
injury.
Save all warnings and instructions for future reference.
Read the instruction manual fully. Do not attempt any operation until you have
read and understood this manual.
Most important you must know how to safely start and stop this machine,
especially in an emergency.
Keep the work area tidy and clean. Attempting to clear clutter from around the
machine during use will reduce your concentration. Mess on the floor creates a
trip hazard. Any liquid spilt on the floor could result in you slipping.
Find a suitable location. If the machine is bench mounted; the location should
provide good natural light or artificial lighting as a replacement. Avoid damp and
dust locations as it will have a negative effect on the machine’s performance.
If the machine is portable; do not expose the tool to rain. In all cases do not
operate power tools near any flammable materials.
Beware of electric shock. Avoid contact with earthed surfaces; because they
can conduct electricity if there is an electrical fault with the power tool. Always
protect the power cable and route it away from danger.
Keep bystanders away. Children, onlookers and passers by must be restricted
from entering the work area for their own protection. The barrier must extend a

suitable distance from the tool user.
Unplug and house all power tools that are not in use. A power tool should
never be left unattended while connected to the power supply. They must be
housed in a suitable location, away locked up and from children.
Do not overload or misuse the tool. All tools are designed for a purpose and are
limited to what they are capable of doing. Do not attempt to use a power tool (or
adapt it in any way) for an application it is not designed for. Select a tool
appropriate for the size of the job.
Overloading a tool will result in tool failure and user injury: This covers the use of
accessories.
Dress properly. Loose clothing, long hair and jewellery are all dangerous
because they can become entangled in moving machinery: This can also result
in parts of body being pulled into the machine.
Clothing should be close fitted, with any long hair tired back and jewellery and
neck ties removed. Footwear must be fully enclosed and have a nonslip sole.
Wear personal protective equipment (PPE). Dust, noise, vibration and swarf
can all be dangerous if not suitably protected against. If the work involving the
power tool creates dust or fumes; wear a dust mask. Vibration to the hand,
caused by operating some tools for longer periods must be protected against.
Wear vibration reducing gloves and allow long breaks between uses. Protect
against dust and swarf by wearing approved safety goggles or a face shield.
These are some of the more common hazards and preventions; however,
always find out what hazards are associated with the machine/work process and
wear the most suitable protective equipment available.
Do not breathe contaminated air. If the work creates dust or fumes; connect
the machine (if possible) to an extraction system either locally or remotely.
Working outdoors can also help if possible.
Move the machine as instructed. If the machine is hand held, do not carry it by
the power supply cable. If the product is heavy; employ a second or third person
to help move it safely or use a mechanical device. Always refer to the instructions
for the correct method.
Do not overreach. Extending your body too far can result in a loss of balance
and you falling. This could be from a height or onto a machine and will result in
injury.
Maintain your tools correctly. A well maintained tool will do the job safely.
Replace any damaged or missing parts immediately with original parts from the
manufacturer. As applicable; keep blades sharp; moving parts clean, oiled or
greased; handles clean; and emergency devices working.
Wait for the machine to stop. Unless the machine is fitted with a safety brake;
some parts may continue to move due to momentum. Wait for all parts to stop;
then unplug it from the power supply before making any adjustments, carrying
out maintenance operations or just finishing using the tool.
Remove and check setting tools. Some machinery requires the use of
additional tools or keys to set, load or adjust the power tool. Before starting the
power tool always check to make certain they have been removed and are safely

away from the machine.
Prevent unintentional starting. Before plugging any machine in to the power
supply, make sure the switch is in the OFF position. If the machine is portable; do
not hold the machine near the switch and take care when putting the machine
down; that nothing can operate the switch.
Carefully select an extension lead. Some machines are not suitable for use
with extension leads. If the tool is designed for use outdoors; use an extension
lead also suitable for that environment. When using an extended lead, select one
capable of handling the current (amps) drawn by the machine in use. Fully
extend the lead regardless of the distance between the power supply and the
tool. Excess current (amps) and a coiled extension lead will both cause the cable
to heat up and can result in fire.
Concentrate and stay alert. Distractions are likely to cause an accident. Never
operate a power tool if you are under the influence of drugs (prescription or
otherwise), including alcohol or if you are feeling tired. Being disorientated will
result in an accident.
Have this tool repaired by a qualified person. This tool is designed to confirm to
the relevant international and local standards and as such should be maintained
and repaired by someone qualified; using only original parts supplied by the
manufacturer: This will ensure the tool remains safe to use.
Additional Safety Instructions For Spray Guns
• Never point or spray the gun at humans or animals.
• Consult the manufacturer of the substance to be sprayed for safety guidelines
specific to the material.
• In the event of the material being sprayed coming into contact with skin, eyes or
taken internally, consult with a doctor immediately and inform them of the
substance involved.
• Never spray flammable liquids, glazes, acidic, caustic, alkaline or substances
containing abrasive or texture (ie grit).
• Do not spray near naked flames or heat sources.
• Always use in a well ventilated area.
• Keep out of the reach of children.
• After thoroughly cleaning the complete spray gun store in a safe, dry location.
• Do not operate the gun empty of fluid as this will cause excess wear internally.
• Oil the nozzle assembly with a light mineral oil on a regular basis.
Connection To The Power Supply
Make sure the power supply information on the machine’s rating plate are
compatible with the power supply you intend to connect it to.
This appliance is Class II and is designed for connection to a power supply
matching that detailed on the rating label and compatible with the plug fitted.
If an extension lead is required, use an approved and compatible lead rated for
this appliance. Follow all the instruction supplied with the extension lead.

Double insulated : This product requires no earth connection as supplementary
insulation is applied to the basic insulation to protect against electric shock in the
event of failure of the basic insulation.
Apart from replacing the fuse in the plug, no other electrical work is
recommended on this machine.

5. OPERATION INSTRUCTIONS
Preparation - Fig.1
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 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 - Fig. 2
Always remember to disconnect from the mains supply before filling
the paint container with spray able material.
Fig.1

Most paints are supplied ready for brush application
and will need to be thinned before they are suitable
to be sprayed. Follow the manufacturer’s 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. The table below
shows recommended times for different types of
material.
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
Aluminum paints 22 - 25 seconds
Wood sealers 28 - 35 seconds
Wood preservatives No thinning required
Wood stains No thinning required
Spraying
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
until the required volume of paint is spraying. Turn the output control in a
clockwise direction to reduce the flow and anti-clockwise to increase the flow.
Adjustment of the output control will affect the spray pattern.
Spraying techniques - Fig .3
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,
using a criss-cross pattern as shown.
Fig. 2

Fig. 3
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
manufacturers drying time recommendations before
applying a second coat. When spraying small areas,
Fig. 4

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.
6. MAINTENANCE
Make sure that the plug is removed from the mains when carrying out maintenance work on
the motor.
The machines have been designed to operate over a long period of time with a minimum of
maintenance. Continuous satisfactory operation depends upon proper machine care and
regular cleaning.
Cleaning and maintenance - Fig. 5.
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 and oiled thoroughly after every use.
Failure to clean and oil 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:
1. Empty any remaining material from the container.
2. Clean the container thoroughly with the thinner that was used.
3. Pour some thinner into the container and spray through the spray gun until
only clean thinner is coming out of the nozzle.
4. Thoroughly clean the paint pick up pipe and filter with thinner.
5. Clean the basket and nozzle and remove any other debris or paint that
remains.
6. Turn the spray gun upside down and apply a few drops of light oil to the two
apertures (Fig 6).
7. switch on the unit for a while, this will lubricate the piston and cylinder.
If your spray gun should require extra internal cleaning, it may be necessary to
disassemble it. (Fig 5)
If so the following action should be taken:
1. Remove the plug from the mains socket.

2. Remove paint container, pick up pipe and filter.
3. Take off the pump assembly.
4. Release the nozzle (H), valve (I), piston (M) and spring (L).
5. Clean the cylinder (K) and all parts thoroughly with solvent.
6. Apply a few drops of light lubricating oil to the piston, spring and cylinder.
7. Reassemble the spray gun.
