suspension gear must ensure that the machinery remains earthed. If the
earthing of the machinery includes the suspension arrangements, then
these must constantly be kept clean in order to guarantee the necessary
conductivity. The appropriate measuring devices must be kept ready in
the workplace in order to check the earthing.
Compressed air
When there are longer pauses or stand-still times between working, the
powder spraying equipment should be drained of compressed air. There
is a danger of injury when pneumatic hoses are damaged and from the
uncontrolled release and improper use of compressed air.
Crushing and cutting
During operation, moving parts may automatically start to move in the
operating area. It must be ensured that only instructed and trained per-
sonnel go near these parts. The operator should ensure that barriers
comply with the local security regulations.
Access under exceptional circumstances
The operating firm must ensure that local conditions are met when re-
pairs are made to the electronic parts or when the equipment is restarted
so that there are additional measures such as barriers to prevent unau-
thorized access.
Prohibition of unauthorized conversions and modifica-
tions to machines
All unauthorized conversions and modifications to electrostatic spraying
equipment are forbidden for safety reasons.
The powder spraying equipment should not be used if damaged, the
faulty part must be immediately replaced or repaired. Only original ITW-
Gema replacement parts should be used. Damage caused by other parts
is not covered by guarantee.
Repairs must only be carried out by specialists or in ITW-Gema work-
shops. Unauthorized conversions and modifications may lead to injury or
damage to machinery. The ITW Gema AG guarantee would no longer be
valid.
Safety requirements for electrostatic powder
coating
1. This equipment is dangerous if the instructions in this operating
manual are not followed.
2. All electrostatic conductive parts, in particular the machinery
within 5 meters of the coating equipment, must be earthed.
3. The floor of the coating area must conduct electricity (normal
concrete is generally conductive).
4. The operating personnel must wear electricity conducting foot-
wear (e.g. leather soles).
5. The operating personnel should hold the gun with bare hands. If
gloves are worn, these must also conduct electricity.
6. The supplied earthing cable (green/yellow) must be connected to
the earthing screw of the electrostatic powder spraying hand ap-
pliance. The earthing cable must have a good metallic connec-
