Nozzle Maintenance

A pulsing sensation felt while squeezing the spray gun
trigger may be caused by excessive pump pressure.
The principal cause of excessive pump pressure is a
spray tip clogged or restricted with foreign materials,
such as dirt, etc. To correct the problem, immediately
clean the spray tip following these instructions:
1. Shut off engine and turn off water supply.
2. Remove spray tip from end of nozzle extension.
3. Remove in-line filter from other end of nozzle
extension.
4. Use a small paper clip to free any foreign material
clogging or restricting spray tip (Figure 15).

5. Using a garden hose, remove additional debris by
back flushing water through nozzle extension
(Figure 16). Back flush between 30 to 60 seconds.
