Spraygun Maintenance Schedule
please observe the recommended maintenance schedule for your spraygun in order to preserve spray
quality and the working life of the unit. If you use heavy wettable powders to spray or if you operate the
spraygun in a dusty environment, you may need to clean liquid and air filters more often than these rec-
ommendations. Visually inspect the nozzle and trigger assembly often and clean as necessary.
Clean the liquid filter assembly
after every spray application
Clean the nozzle
when spray pattern is different than when the
spraygun was new
recharge batteries in spraygun
when charging indicator does not light during
operation (about every 8 operational hours)**
replace batteries in spraygun
when batteries no longer hold a sufficient
charge to complete a ten-hour work session
or show other signs of battery deterioration
All operators must read this Owner’s Manual completely and thoroughly
before operating the Spraygun. They must be familiar with all operating
instructions and safety precautions.
