Special cleanup
Perform the following procedure after spraying
with water-based materials only.
Attention
Perform the following procedure when the valves of the
sprayer are stuck or when preparing the sprayer for long term
storage. The use of a pump cleaning adapter that attaches to
the bottom of the siphon tube is required (the pump cleaning
adapter is included with the sprayer).
1. Lock the gun and remove the spray tip assembly. If
necessary, loosen the gun holder clamp knob and then
engage the spray gun trigger lock. Move the spray gun
to its original position and tighten the clamp knob.
