• When the water supply is steady and constant, engage

Check In-Line Filter
Refer to Figure 15 and service the in-line filter if it
becomes clogged, as follows:
1.
Detach spray gun and nozzle extension from high
pressure hose. Detach nozzle extension from spray gun
and remove o-ring and screen from nozzle extension.
Flush the screen, spray gun, and adjustable nozzle
extension with clean water to clear debris.
2.
If the screen is damaged, the o-ring kit contains a
replacement in-line filter screen and an o-ring. If
undamaged, reuse screen.
3.
Place the in-line filter screen into the threaded end of
the nozzle extension. Direction does not matter. Push
the screen in with the eraser end of a pencil until it
rests flat at the bottom of the opening.Take care to
not bend the screen.
4.
Place the o-ring into the recess. Push the o-ring snugly
against the in-line filter screen.
5.
Assemble the nozzle extension to the spray gun, as
described earlier in this manual.
Cleaning Detergent Siphoning Tube
If you used the detergent siphoning tube, you must flush it
with clean water before stopping the engine.
• Place the detergent siphoning tube in a bucket full of
clean water.
• Slide the adjustable nozzle forward to the low pressure
position. Flush for 1-2 minutes.
• Shut off the 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 nozzle
clogged or restricted with foreign materials, such as dirt,
etc.To correct the problem, immediately clean the nozzle
using the tools included with your pressure washer and
follow these instructions:
1.
Shut off the engine and turn off the water supply.
2.
Detach the nozzle extension from the spray gun.Twist
the nozzle clockwise to the stream position. Using the
supplied 2mm (5/64) allen wrench, remove the nozzle
from the end of the nozzle extension (Figure 16).
3.
Remove the in-line filter from the other end of the
nozzle extension.
4.
Use the wire included in the kit (or a small paper clip)
to free any foreign material clogging or restricting the
nozzle (Figure 16).
