Cleaning - Routine

The spray gun does not have to be necessarily dismantled for cleaning if and when
when the spraying medium is changed in regular intervals or upon termination of
work (depending, of course, on the material used).
Note
It is recommended to clean and lubricate the spray gun frequently in accordance with
6.2 Cleaning - Complete. This will ensure a functional reliability of the spray gun.
The following requirements must be met before the routine cleaning work can be per-
formed:
1. The material tank must be clean and then be filled with a compatible cleaning solu-
tion. The material pressure must be available at the gun.The cleaning solution
should never be sprayed.
2. Take the spray gun into operation (see 5.2 Starting/Stopping Requirements).
3. Do not stop the spray gun until clear cleaning solution emerges from the nozzle.
The material input of the PILOT WA 200 can be released manually so that the
complete spraying system does not have to be taken into operation.
1. Pull the pull rod pos. 25 of the spray gun backwards. The material inlet is now
open and both the material duct and the material control needle will be cleaned.
2. Do not let go of the pull bar until clear cleaning solution emerges from the spray
gun.
All pressures should be removed from the complete spraying system until it is taken
into operation again.
