CHECK SPRAY GUN
Examine the hose connection to the spray gun and make sure it is secure, and
make sure the 'safety lock' is present and attach on the trigger, it helps to prevent
any accidental jets when in operation. Replace spray gun immediately if the safety
lock is damaged or not functioning.
CHECK WAND
Occasionally, the spray wand can be clogged with foreign materials such as dirt.
When this happens, excessive pressure can develop. Whenever the pressure
nozzle becomes partially clogged, the pump pressure will pulsate. It should be
cleaned immediately cleaned.
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.
ALWAYS point spray gun in safe direction, squeeze spray gun trigger to
release retained high water pressure.
3.
Remove spray tip from end of nozzle extension.
4.
Use a small paper clip to free any foreign material clogging or restricting
spray tip of the nozzle.
5.
Remove nozzle extension from spray gun.
6.
Using a garden hose, remove additional debris by back flushing water
through the nozzle extension.
7.
Reinstall spray tip into nozzle extension.
8.
Reconnect nozzle extension to spray gun.
9.
Make sure garden hose is connected to spray gun and pump. Turn on water.
10. Start engine following instructions 'How to Start Your Pressure Washer'.
11. Test pressure washer by operating the spray gun
12. Use same nozzle maintenance with the Surface-Cleaner.
If pressure drops off check nozzle for wear. Nozzles should be replaced on a
regular basis (suggestion: every month for machines in regular use, every three
months for machines used intermittently). Using the machine with the incorrect
nozzle size or worn nozzle will VOID WARRANTY and can be DANGEROUS to
operator.
