4
Wear static dissipative gloves when spraying. The grounding takes place via the spray
gun's handle or its trigger.
4.2.4 Product Hoses
Danger due to bursting of product hose!
The product hose is under pressure and may cause dangerous injuries.
4
Ensure that the hose material is chemically resistant to the sprayed products and the
flushing agents used.
4
Ensure that the product hoses and the fittings are suitable for the pressure generated.
4
Ensure that the following information can be seen on the high-pressure hose:
4
Manufacturer
4
permissible operating pressure
4
Date of manufacture
4
Make sure that the hoses are laid only in suitable places. Hoses should not be laid in the
following places under any circumstances:
4
in high traffic areas
4
on sharp edges
4
on moving parts
4
on hot surfaces
4
Ensure that the hoses are never run over by vehicles (e.g., fork lifts), or that the hoses
are never put under pressure from the outside in any other way.
4
Ensure that the hoses are never kinked. Observe maximum bending radii.
4
Ensure that no work is ever performed with a damaged hose.
4
Make sure that the hoses are never used to pull or move the device.
4
The electrical resistance of the product hose, measured at both valves, must be less
than 1 MΩ.
4
Suction hoses may not be subjected to pressure.
4.2.5 Cleaning and Flushing
Danger due to cleaning and flushing!
Explosion hazard and damage to the device.
4
Non-ignitable cleaning agents and flushing agents should preferably be used.
4
When carrying out cleaning work with flammable cleaning agents, make sure that all
equipment and resources (e.g., collection tank, funnel, transport cart) are conductive or
static dissipative and grounded.
4
Observe the specifications of the lacquer manufacturer.
4
Ensure that the flash point of the cleaning agent is at least 15 K above the ambient
temperature or that cleaning is undertaken at a cleaning station with technical
ventilation.
4
Never use chloride or halogenated solvents (such as trichloroethane and methylene
chloride) with devices containing aluminium or galvanized/zinc-plated parts. They may
react chemically thus producing an explosion danger.
4
Take measures for workplace safety.
