Daily Maintenance
Perform the following procedures daily.
Filling the Wet Cup Reservoir With Oil
Before you start to spray each day, put a tablespoon of piston
seal lubricant (Piston Lube) into the wet cup in the upper
pump housing.
It is important to maintain lubricant in the wet cup to prevent
materials from adhering to the piston rod, which becomes
abrasive to the upper seals. Piston Lube (see the Accessories
section of this manual) will break down any material that may
accumulate in the wet cup and keep it from drying.
Cleaning the Intake Screen
1. Remove the intake screen
and clean with a solvent
appropriate to the type of
material being used.
Spray Gun Maintenance
Cleaning the Spray Tip
1. Flush the gun with the appropriate solvent immediately
after the work is completed.
2. Oil the retractor 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.
