STORAGE & MAINTENANCE

SPECIFIC MAINTENANCE:

ENGINE: The engine instructions that accompany your unit detail specific
procedures for maintenance of the engine. Following the engine
manufacturer's recommendations will extend engine work life.
PUMP: This unit is supplied with a maintenance free pump.
NOZZLES: Nozzle orifices should be kept clean and free from obstructions.
To clean nozzle orifice:
1. Disconnect the wand from the gun.
2. Insert the nozzle cleaner into the nozzle and rotate. (See
drawing, left.)
3. Flush the nozzle with water.
4. Reconnect the wand to the gun assembly.
5. Turn the unit "ON". Point the gun in a safe direction and trigger
the gun to begin spraying. Adjust spray pattern to 0°. If spray
pattern is still distorted, repeat steps 1-4. If you are unable
to thoroughly clean the nozzle using this procedure, then the
nozzle must be replaced. Water flow through the spray nozzle
will erode the orifice, making it larger, resulting in a pressure
loss. Nozzles should be replaced whenever pressure is less
than 85% of the maximum. The frequency of replacement will
depend upon such variables as mineral content in the water
and number of hours the nozzle is used.
To remove or replace adjustable nozzle:
1. Insert a 2.0 mm allen wrench into the nozzle.
2. Rotate the wrench counterclockwise to remove the nozzle.
3. Inspect the nozzle and clean or replace before reinserting.
