Cleaning and maintenance
Injector cleaning
Cleaning should be done daily before starting work or at color change:
1. Remove the injector from the hopper
2. Pull powder hose off the hose fitting (
4
)
3. Clean the hose fitting (
4
) with compressed air which is free of
water and oil and check for wear
4. Clean injector body (
1
) with compressed air which is free of
water and oil. Any contamination can be seen through the
opening of the powder hopper fitting (

)
5. Reassemble the injector and fit it on the hopper
Attention:
If the injector is severely contaminated, it must be dismantled! Re-
move the check valves (6 and 7) with the correct sized spanner.
Clean the parts with compressed air and, if necessary, dissolve sin-
tered deposits with nitro-thinners!
Don't use acetone, don't scrape!
