Cleanup
• Release system and spray gun pressure before
cleaning or performing maintenance on the gun.
• Use only the cleaning solvent recommended by the
material manufacturer.
• Never spray into an enclosed vessel (this will create
an explosive gas / air mixture).
Daily cleaning
1. Flush out the spray gun material tube thoroughly with the
appropriate solvent.
2. Unscrew the tip guard and remove the air cap. Take out
the tip and immerse in the appropriate solvent until all
traces of material are dissolved. Remove the tip and put
into the appropriate solvent for 1 to 2 days until all
material residues are gone.
4. Clean the spray gun body using a brush.
Hold spray gun downward or horizontal while cleaning the
spray gun. Cleaning solvent must not be allowed to enter
the air channels as this will cause swelling of the O-rings.
Maintenance
Adjusting the Needle Packing
If material begins leaking at the valve rod, flush the gun and
carefully tighten the packing screw using the gun spanner that
came with this gun.
CAUTION
NOTE: Handle the tip with care. Do not clean it with
sharp metal objects. Use tip cleaning brush
(P/N 9997001) only. If necessary, use
corresponding tip cleaning needle (P/N
8612001, set of 12) for cleaning tip.
