Priming Pump
1. Put prime/pressure relief valve UP to priming posi-
tion.
2. Turn pressure control knob to prime/clean position
in line with red indicator dot.
3. Disengage trigger lock and trigger sprayer for three
seconds, then release trigger.
4. Turn pressure control knob counter-clockwise to
lowest position. Put prime/relief valve to DOWN
position to spray.
NOTE: A small amount of air may be introduced into
the cup from the pump while priming. Slightly tip unit
and squeeze liner to purge final amount of air if
desired.
Setting Pressure
NOTE: Spraying water, solvents, and thin materials (low
viscosity materials) at high pressure (setting “2” or
higher with yellow light flashing) can result in temporary
pump leaking. To avoid, read and follow instructions
(Quick Guide or Manual) on how to properly adjust pres-
sure.
1. To reduce overspray and extend battery life, always
spray at lowest pressure that produces an accept-
able spray pattern.
2. Dial in pressure by spraying material on a scrap
material.
3. You MUST start with dial at “1” and gradually
increase by increments of “1” or less until desired
spray pattern is achieved. Put pressure relief handle
in UP position to turn pressure control knob, then
return handle to DOWN position to spray.
NOTE: After storage, the piston seals need to be
energized prior to next use to prevent leakage. To
energize, follow steps below:
a. Prime system with flushing fluid.
b. Spray at low pressure setting “1” for 10 sec-
onds.
c. Drain fluid. You are now ready to spray.
