Cleaning the Spray Tip
1. Flush the gun with solvent immediately after the work is
completed.
2. Oil the sliding pins to prevent them from seizing up.
Should the spray tip become clogged,
reverse the spray tip with the lever and
pull the trigger. Once the obstruction
comes out of the spray tip, release the
trigger, reverse the spray tip back to the
spray pattern setting, and resume
spraying.
Do not attempt to clean the tip with your finger.
Do not use a needle or other sharp pointed instrument to
clean the tip. The hard tungsten carbide is brittle and can
be chipped.
