10. Maintenance and repairs
Warning!
Risk of injuries from components coming loose or leaking
material.
If maintenance work is performed while the gun is still connected to the
compressed air circuit and material supply, components can unexpect-
edly work loose and material can leak.
→ Disconnect the spray gun from the compressed air circuit and the
material supply before any maintenance work.
→ Depressurise the system.
All parts of the spray gun that convey material, the material supply and
lines are under high pressure (up to 250 bar).
→ Hoses and connection systems must be rated accordingly.
