Cleaning Chemical Injection Hose
If you used the chemical injection hose, you must flush it
with clean water before stopping the engine.
1.
Place chemical injection hose in a bucket full of clean
water.
2.
Slide adjustable nozzle forward to low pressure
position. Flush for 1-2 minutes.
3.
Shut off engine.
IMPORTANT: Simply shutting OFF engine will not
release pressure in the system. When the engine has
shut down, squeeze the trigger on the spray gun to
relieve the pressure in the hose.
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 orifice
clogged or restricted with foreign materials, such as dirt,
etc.To correct the problem, immediately clean the orifice
using the tools included with your pressure washer and
follow these instructions:
1. Shut off engine and turn off water supply.
2. Detach nozzle extension from spray gun.Twist nozzle
clockwise to stream position. Using 2mm (5/64) allen
wrench, remove orifice from end of nozzle extension
(Figure 15).
