10- RISKS
10.1. Depending on the products used, there may be danger of fire; avoid smoking and open flames while spraying potentially flammable
products.
10.2. Danger of ejection of the adjustment handwheel: do not exceed the specified adjustment limits.
11- TROUBLESHOOTING
PROBLEMS
The gun does not spray when control
trigger is pressed
Irregular spraying
Difficulty is screwing on the cartridge
12- MAINTENANCE
12.1 Disconnect the spray gun from the supply.
12.2 Empty out the product from the spray gun, or remove the container cartridge.
12.3 Pour into the tank the necessary amount of thinner (usually ½ litre) suitable for cleaning the product being used.
12.4 Close the tank and connect the spray gun again.
12.5 Spray the solvent, directing the jet into a special container.
Make sure that the air-product adjustment handwheel is completely closed to avoid atomization of the solvent which may lead to pollution of the
nearby environments.
Do not immerse the spray gun completely into the solvent, but rather clean it with a brush or a cloth
12.6 In case the product leaks out around the needle and stuffing box screw, in front of the trigger (see fig. 1 point 13), clean the fouled parts immediately, turn
the stuffing box screw clockwise so as to hermetically seal the stuffing box installed in spray gun. This will prevent the product from leaking again. Finally, make
sure that the closing needle remains free to move.
12.7 Whenever necessary, lubricate the needle at the height of the stuffing box screw.
12.8 Occasionally, lubricate the air valve rod.
When the spraying job is finished, or during a pause , hang the spray gun on the special hook
A clogged spray gun may damage the cartridge. Always keep the nozzle and suction clean.
