A clogged spray nozzle can cause the spray pressure
and fl owrate to drop. All excessive pressure will go back
to the sprayer tank.
To correct the problem, immediately clean the spray tip by
following these instructions:
1. Stop engine & remove the unit from the operators back.
2. Disconnect the spray rod from the spray hose as-
sembly.
3. To remove the nozzle cap (7/9), turn in anticlockwise
direction.
4. Inspect and clean the spray tip (8/10) and metal
strainer (11) for 3-nozzle spray rod from any foreign
material clogging or restricting the spray nozzle. Re-
place if damaged.
5. Reinstall the nozzle cap and the spray rod with the
spray hose assembly tighly (hand tighten) .
