GENERAL POWER TOOL SAFETY WARNINGS
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.
The term “power tool” in the warnings refers to your mains-operated (corded) power tool or battery-operated (cordless) power tool.

1. Work area safety
   • Keep the work area clean and well lit. Cluttered or dark areas invite accidents.
   • Do not operate power tools in explosive atmospheres, such as in the presence of flammable liquids, gases or dust. Power tools create sparks which may ignite the dust or fumes.
   • Keep children and bystanders away while operating a power tool. Distractions can cause you to lose control.
2. Electrical safety
   • Power tool plugs must match the outlet. Never modify the plug in any way. Do not use any adapter plugs with earthed (grounded) power tools. Unmodified plugs and matching outlets will reduce risk of electric shock.
   • 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.
   • Do not expose power tools to rain or wet conditions. Water entering a power tool will increase the risk of electric shock.
   • 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.
   • 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.
   • If operating a power tool in a damp location is unavoidable, use a residual current device (RCD) protected supply. Use of an RCD reduces the risk of electric shock.
3. Personal safety
   • 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.
   • Use personal protective equipment. Always wear eye protection. Protective equipment such as dust mask, non-skid safety shoes, hard hat, or hearing protection used for appropriate conditions will reduce personal injuries.
   • Prevent unintentional starting. Ensure the switch is in the off-position before connecting to power source and/or battery pack, picking up or carrying the tool. Carrying power tools with your finger on the switch or energising power tools that have the switch on invites accidents.
   • 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.
   • Do not overreach. Keep proper footing and balance at all times. This enables better control of the power tool in unexpected situations.
   • 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.
   • If devices are provided for the connection of dust extraction and collection facilities, ensure these are connected and properly used. Use of dust collection can reduce dust related hazards.
   • Do not let familiarity gained from frequent use of tools allow you to become complacent and ignore tool safety principles. A careless action can cause severe injury within a fraction of a second.
4. Power tool use and care
   • 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.
   • 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.
   • Disconnect the plug from the power source and/ or the battery pack from the power tool before making any adjustments, changing accessories, or storing power tools. Such preventive safety measures reduce the risk of starting the power tool accidentally.
   • 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.
   • Maintain power tools. Check for misalignment or binding of moving parts, breakage of parts and any other condition that may affect the power tool’s operation. If damaged, have the power tool repaired before use. Many accidents  are caused by poorly maintained power tools
   • Keep cutting tools sharp and clean. Properly maintained cutting tools with sharp cutting edges are less likely to bind and are easier to control.
   • Use the power tool, accessories and tool bits etc. in accordance with these instructions, taking into account the working conditions and the work to be performed. Use of the power tool for operations different from those intended could result in a hazardous situation.
   • Keep handles and grasping surfaces dry, clean and free from oil and grease. Slippery handles and grasping surfaces do not allow for safe handling and control of the tool in unexpected situations.
5. Battery tool use and care
   • Recharge only with the charger specified by the manufacturer. A charger that is suitable for one type of battery pack may create a risk of fire when used with another battery pack.
   • Use power tools only with specifically designated battery packs. Use of any other battery packs may create a risk of injury and fire.
   • When battery pack is not in use, keep it away from other metal objects, like paper clips, coins, keys, nails, screws or other small metal objects that can make a connection from one terminal to another. Shorting the battery terminals together may cause burns or a fire.
   • Under abusive conditions, liquid may be ejected from the battery; avoid contact. If contact accidentally occurs, flush with water. If liquid contacts eyes, additionally seek medical help. Liquid ejected from the battery may cause irritation or burns.
   • Do not use a battery pack or tool that is damaged or modified. Damaged or modified batteries may exhibit unpredictable behaviour resulting in fire, explosion or risk of injury.
   • Do not expose a battery pack or tool to fire or excessive temperature. Exposure to fire or temperature above 130 °C may cause explosion. NOTE The temperature „130 °C“ can be replaced by the temperature „265 °F“.
   • Follow all charging instructions and do not charge the battery pack or tool outside the temperature range specified in the instructions. Charging improperly or at temperatures outside the specified range may damage the battery and increase the risk of fire.
6. Service
   • Have your power tool serviced by a qualified repair person using only identical replacement parts. This will ensure that the safety of the power tool is maintained.
   • Never service damaged battery packs. Service of battery packs should only be performed by the manufacturer or authorized service providers.

OPERATION

Preparing the spray gun for use

Step 1: Viscosity/diluting of the paint
This appliance can process spray materials up to max. 70 DIN/sec (viscosity). Low-viscosity coating substances, water- and solvent-based paints, finishes, primers, 2 component paint, clear finishes, staining sealers and wood sealer preservatives often do not need diluting. High-viscosity Wall paints, thick varnishes and thick stains often do need diluting.

Tip! With low-viscosity use the smaller nozzle and with high-viscosity use the bigger nozzle.
Warning! Always use wall paint that is smooth and without any granules or lumps. Otherwise the nozzle will become clogged

PAINT PREPARATION
Check/test the viscosity of the to be sprayed material.

• Put the stirring rod (12) in the container(11) which includes the to be sprayed material and pull it out and see how the material drips. When it looks like liquid chocolate, this material is ok for testing at step 4 (Test and adjusted the spray jet effect, spray volume and spray flow).

When the spraying material is very thick and gel-like, dilute it by 5 or 10%.
For small batches this can easily done by using the special stirring rod:

1. Put the stirring rod (12) in the container like shown in figure E1 and add spray material up to one of the lines. Like shown in figure E2.

2. For 10%: Add the suitable thinning solvent up to the next line.
   For 5%: Add the suitable thinning solvent up to half of the next line.

3. Stir the thinning solvent through the spray material until it is completely mixed.

Check viscosity again, when it looks like liquid chocolate, this material is ok for testing at step 4 (Test and adjusted the spray jet effect, spray volume and spray flow). Still to thick? Repeat the process by adding an additional 5 or 10% thinning solvent.
Tip! Most wall paints are thick and may need up to 40% dilution.

Step 2: Preparing the spray surface

• Cover the area around the to be sprayed area thoroughly and over a wide area. Any surface that is not covered properly can unintentionally be sprayed.

Warning! Be aware of your surroundings when spraying outside, wind can cause unintentional spraying of your not covered surroundings

• The spray surface needs to be clean, dry, and free from grease or dust.
• Polished surfaces should be lightly sanded, and the sanding dust removed.

Step 3: Filling the paint container

• Remove the container (11) from the Spray unit.
• Fill the container with to be sprayed material to a maximum of 800ml.
• Adjust the riser pipe (23) according to the position you are going to use the spray gun in. Spraying angle up like show in Fig. F. spraying angle down like show in Fig. G
• Make sure the gasket and riser pipe (23) are properly installed in the container cap (10). Tighten the container (11) onto the container cap (10).

Step 4: Test and adjust the spray jet effect, spray volume and spray flow. (Fig. A + B)
Note: Before starting to spray the work surface, it is advisable to make an initial test by spraying a small area on scrap material.
Tip! With low-viscocity use the smaller nozzle and with high-viscocity use the bigger nozzle.

1. Choose the jet effect: Horizontally or vertically . By turning the nozzle adjusting ring (16) left or right.

2. Adjust the spray volume with Spray volume adjusting wheel (9) by turning it to the left – to reduce the volume, to the right + to increase. Note: Low volume is advised for smaller object or surfaces. High volume is advised or bigger surfaces.
   Tip: We recommend starting at the minimum setting.

3. Adjust the spray flow by using the spray flow adjustment knob(2): turn the knob to the left to reduce the flow, to the right to increase the flow.
   Note: The thinner the paint the lower the flow should be, when using thicker paint make sure to use a higher flow.
   Tip: Several light layers rather than one thick layer will help prevent the paint running.

4. Aim the spray gun to the to be sprayed surface and pull the trigger (1). Hold the front of the spray gun around 20-30 cm away from the to-be-sprayed surface. Make long arm movements rather than short wrist movements like show in figure H. The most suitable method of surface spraying is with a cross-pattern, starting with horizontal passes and finishing with light vertical passes. See figure J.

5. Release the trigger (1) to stop the spraying.

6. Check Spray Pattern Quality
   A good spray pattern is evenly distributed as it hits the surface, if not (add highest spray flow) check the following:

   • Spray tip may be worn.
   • A smaller spray tip may be needed.
   • Material may need to be thinned.

7. Adjust the Jet effect (step A), spray volume (step B) and Spray flow (step C) depending on the paint, object- surface to be sprayed and desired coverage. Repeat steps D to H when not satisfied with the test results.

Always let the paint/varnish/stains dry according to the recommend dry time of the spray material for applying multiple coats. Several light coats rather than one thick coat will help prevent the paint running.

MAINTENANCE

Before cleaning and maintenance, always switch off the machine and remove the battery pack from the machine.

Cleaning after each use
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 the next time. The guarantee does not cover a sprayer that has not been properly cleaned by the user.

The following action must be taken after every use:

1. Empty any unused paint from the paint container (11). Never leave paint to dry in the unit (container, riser pipe, needle, nozzle), as dried paint will prevent the spray gun from functioning properly. Failure to observe this important cautionary measure will void the guarantee.
2. Clean the container thoroughly with the thinner solvent you have used.
3. Put a little thinner solvent into the container and spray until only clean, thinner solvent exits the spray gun.
4. Clean the gasket and riser pipe (23) with thinner solvent.
5. Clean the nozzle and remove all remaining dirt or paint.
6. – Remove the nozzle nut (17), nozzle head (15), Nozzle (14) and nozzle needle (13) like explained in chapter replacing the nozzle.
   • Clean all the nozzle parts thoroughly, do not let them soak in any cleaning detergent or water.
7. If the cylinder hole becomes blocked, use a suitable cylinder cleaning needle.
8. Keep the ventilation slots of the device clean to prevent the motor from overheating.
9. The ventilation slots must be free from dust and dirt. If the dirt cannot be removed, use a soft cloth dipped in soapy water. Never use solvents such as benzene, alcohol, ammoniac etc. These solvents may attack the plastic elements
10. The air filter (22) must be free from dust and dirt. Ones in a while you need to clean the air filter. Remove the air filter like explained in chapter “cleaning and replacing the air filter”.
11. Clean the outside of the machine
    • Clean plastic parts with a soft, clean cloth, preferably after each use.
    • Do not use aggressive cleansers (solvents or abrasive cleansers), or an abrasive sponge or sharp objects.

Do not put or immerse product in water or any other liquid. Always read the precautions laid down by the paint/varnish manufacturer.

• Do not use liquids containing abrasive substances such as red lead oxide, glazes, caustic, and alkaline substances. The use of these liquids can lead to excessive wear or corrosion to the pump assembly.

Cleaning/replacing the air filter (Fig. B)

• Loosen the screw (20) on the backside of the machine.
• Remove the air filter cover (21) and take out the air filter (22).
• Clean the air filter (22), always make sure it is dry before placing it back.
• Place the dry air filter/replacing air filter back in the motor unit (8).
• Place back the air filter cover (21) and tighten with the screws (20).
