3. SAFETY
Warning: Read all safety warnings and all instructions. Failure to follow the warnings and instructions may result in serious injury.
3.1 WORK AREA & PERSONAL SAFETY
•Keep work area clean and well lit. Cluttered or dark areas increases accidents.
•Ensure all connections and couplings are secure and hold the open end of the hose firmly to avoid
uncontrolled “whipping” of the hose.
•Adjust the air regulator on your compressor to reduce the air pressure to meet the tool requirements.
•Ensure the air compressor are equipped with a pressure gauge, safety release valve and a pressure gauge
valve located at the bottom of the compressor.
•Never use compressed air near flammable liquids.
•Stay alert, consider what you are doing when operating an air tool. Poor attention while operating an air tool
may result in serious personal injury.
•Do not overreach. Proper footing and balance is crucial at all times as this enables better control of the tool.
•Flying particles and debris can result in eye injuries, cuts/scrapes or other significant injuries to almost any
body part, use the correct personal safety equipment for every job.
•Never point the nozzle of any tool or air hose at any person or object apart for those that are part of the
project.
•Keep children and animals away. Be aware of who is in your work area.
•Store equipment safely. Keep air tools locked away in a dry location, away from children.
•Always wear proper safety gear.
•Use compressed air only for the work it is intended for.
•Wear a respirator mask to protect against the inhalation of dust/fumes.
•Never spray paint or oil close to a source of heat or flame.
•Work in a fully ventilated area with access to fresh air.

Warning: Read all safety warnings and all instructions. Failure to follow the warnings and instructions may result in serious injury
•Make sure your paint is suitable for spraying. (Refer to paint manufacturer specifications)
•Keep all the air tools disconnected from the air supply when not in use.
4. GETTING STARTED
4.1 ASSEMBLY
•The position of the Air Cap Horns (1) will determine the spray pattern. To rotate the Air Horns, loosen the Air
Cap, rotate the horns to the desired pattern and tighten
•Check to see that all nuts & bolts are tight.
•To ensure there are no unwanted particles entering the spray gun, blow out some of the air from the air
hose before connecting it to the spray gun.
•The spray gun has been treated with an anti-corrosive agent, before leaving the factory and must therefore
be flushed out with thinners, before use
•Important: Ensure that the Air Volume Control Knob (7), is open by turning it counter clockwise. Whilst
depressing the trigger partially, open (7) above, until desired airflow is obtained
Note: When using an Inline Air regulator, fully open the Air Volume Control Knob (7) and adjust the desired air
flow on the regulator’s adjustment knob.
4.2 GENERAL
•Pressurized air can be dangerous. Ensure you fully understand all the precautions relating to the use of your
air compressor and a compressed air system.
•Inspect the condition of your equipment. Check your air tools and air compressor regularly for damaged
parts.
•Carefully note when dusting your work area. This can create airborne particles that will put you and others at
risk of injury.
•Avoid trying to stop a whipping hose. The force of the hose can cause injury or damage. Shut the air at the
main valve and wait for hose to settle.
•Do not create trip hazards with air hoses. Suspend or guard hoses with boards.
•Isolate and bleed all air-lines and hoses before disconnecting. To disconnect air-lines under pressure is
hazardous.
4.3 OPERATING INSTRUCTIONS SUCTION CUP SPRAY GUN
4.3.1 GENERAL INFORMATION
•This spray gun is suitable for most types of paints (ensure that your paint is suitable for spraying, check paint
supplier details for thinning paint)
•The spray gun is suction fed with paint from the paint container.
•The air that flows through the air cap draws paint into the nozzle chamber, where it is atomized and pushed
forward to create a spray.
•An air compressor with 100L tank with motor power of min 2.5 HP (1.8kW) that can deliver a minimum flow
rate of 85 - 113L/min (3-4 CFM) is recommended.
4.3.2 BEFORE PAINTING
•Thin the paint to the specified viscosity for spraying according to the paint manufacturer’s instructions. The
gun is already equipped with a gravity filter.
•Recommended to fill the paint cup no more than ¾ full. Cover the cup with the lid and keep clean and free
from dried paint flakes.
•Always keep the container vent clear to avoid an air lock restricting paint flow.

Warning: Read all safety warnings and all instructions. Failure to follow the warnings and instructions may result in serious injury
WARNING: NEVER ATTEMPT TO SPRAY UNLESS YOU ARE WEARING THE CORRECT SAFTEY EQUIPMENT SUCH
AS APPROVED RESPIRATORY MASK AND EYE PROTECTION.
•Some specialized paints require specialist respiratory protection.
•Always consult the paint manufacturer’s instructions.
•Mask all areas that are not to be sprayed and ensure that surrounding equipment are covered from
overspray.
•Ensure that the material as well as the area in which you will be spraying is clean and dust-fee.
•For the best results, the surface to be sprayed must be well prepared.
•Connect your air hose to an air supply (compressor), the spray gun can then be connected to the hose
coupler.
4.3.3 HANDLING
•Proper handling of the spray gun will help you achieve the desired paint coating.
•Hold the spray gun perpendicular and in an upright position with the spraying area and then move it left to
right parallel to the spraying area several times appropriate distance of 150 –300mm between the gun and
spraying area
•Note that the stroke should be started before the trigger is pulled and the trigger should be released before
the stroke is ended.
Note: It is recommended to add a mini filter below the gun to trap moisture build up. Moisture may enter
the nozzle chamber and severely affect the paint coating finish.
Recommended to use Air Craft SG F01 mini filter and SG R01 inline regulator
5. MAINTENANCE
•Clean the spray gun immediately after each use, by unscrewing and disassembling the air cap, fluid
nozzle or paint needle.
•Use a brush with thinners to clean the air cap, fluid nozzle, and other parts.
•To flush the material-conveying parts of the spray gun, depress the gun trigger until all material
traces are removed and the gun is thoroughly cleaned.
•Never soak the gun completely.
•Thoroughly clean parts, ensuring the removal of all paint and dried material.
•Empty the paint cup and clean cup with some thinners. Afterwards fill the cup with thinners, spray
thinners to thoroughly flush out passage-ways.
•Inadequate maintenance of the hose can result in hose leakage, bursting and other failures, which
can cause serious injury or property damage.
•Use a “tooth pick” or similar soft material to clean out clogged nozzles and rinse out properly with
suitable solvent or thinners. Blow the components with air to dry-clean.
•Lubricate all working points with spray gun lube.
