MAINTENANCE
CAUTION: Before undertaking any work on the appliance always
turn power switch OFF and detach the plug from the power
socket.
Undertake only the maintenance operations described in the user instructions.
CLEANING
A clogged and partially clogged nozzle can cause a significant reduction of water coming
out of the nozzle and cause the unit to pulse while spraying.
To clean out nozzle:
Turn OFF and unplug unit.
Turn off water supply. Relieve any pressure trapped in the hose by squeezing
trigger 2-3 times.
Separate lance from gun.
Rotate nozzle to the narrow stream setting. This opens up the fan blades.
Use included tip cleaner, or an unfolded paper clip, insert wire into the nozzle
hole and move back and forth until debris is dislodged.
Remove additional debris by back-flushing water through the nozzle. To do this,
place end of garden hose (with water running) to end of nozzle for 30-60
seconds.
