• When the water supply is steady and constant,
engage the safety latch.
To remove contaminants from the pump, follow
these steps:
• Set up the pressure washer as described in
“Preparing Pressure Washer For Use” (page 5).
Connect the water supply and turn water on.
• Remove the nozzle extension from the spray gun.
• Start the engine according to instructions in “How To
Use Your Pressure Washer” (page 8).
• Squeeze the trigger on the spray gun and hold.
• When the water supply is steady and constant,
engage the safety latch and refasten the nozzle
extension.
Check In-Line Filter
Refer to Figure 16 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.
• Insert detergent siphoning tube into clip on handle.
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
If the adjustable nozzle becomes restricted or clogged
with foreign materials such as dirt, excessive pump
pressure may develop. A partially clogged nozzle
causes a pulsing sensation during use.
If the adjustable nozzle becomes clogged or partially
restricted, immediately clean the nozzle with the kit
included with your pressure washer by following these
instructions:
• Shut off the engine and turn off the water supply.
• Separate the nozzle extension from the spray gun.
• Adjust the nozzle extension to the stream position.
• Remove the nozzle from the end of the nozzle
extension (Figure 17) using a 2mm or 5/64 allen
wrench (like the one included in the kit).
