4.3 PARTICULAR DANGER SPOTS
1. The flow of material escaping from the airless gun is under great pressure and thus has a pow-
erful cutting effect.
You must therefore never point the airless gun at yourself or any other person, animal
or plant. Never touch the spray jet with your fingers or hand, or hold them in front of
the airless gun.
Note:
If the cutting effect of the flow of material causes injury seek medical advice immediately. Tell
the doctor which spray material (paint) and/or solvent (thinners) was involved and provide the
relevant information from the manufacturer as per the safety data sheet (supplier, his phone
number, the material number).
2. The escaping spray material generates recoil power. You must therefore always hold the air-
less gun securely and make sure that you have a well-balanced stance.
3. In enclosed systems, or systems which are under pressure, where aluminium or galvanised
parts come into contact with the liquid, there can be dangerous chemical reactions if 1.1.1 tri-
chloroethane, methylene chloride or other solvents containing halogenated chlorinated hydro-
carbons, are used.
If you use the named solvents or paints which contain these solvents, we recommend that you
contact the spray material manufacturer or ITW Oberflächentechnik.
4. If there are malfunctions or obstructions, you must immediately shut off the compressed air
supply at the ball valve. Disconnect the unit from the compressed air system, operate the air-
less gun and open the high pressure filter relief valve before removing the airless gun or the
hose.
5. To prevent static charging from causing a fire or an explosion, the equipment must be properly
grounded (the pump, the material tank, the object to be coated). If using materials with a flash
point under 21°C (e.g. nitro) of ignition group G1-G3, there must be an additional conductive
connection between the material tank and the pump (potential equalisation cable). The material
tank must always be made of metal.
6. Prevent spray back into a closed tank, as an ignitable gas/air mixture will build up. Take particu-
lar care with materials with a flash point less than 21°C (e.g. nitro).
7. The A-weighted sound level of pumps may exceed 85 dB (A).
Local conditions may dictate a higher noise level, which could cause noise deafness. If this is the
situation, operating personnel must be protected by suitable protective equipment or safety meas-
ures.
