In-line Filter
1. Detach gun and lance from high pressure hose.
Detach lance from gun and remove o-ring and
screen from lance. Flush the screen, gun, and
lance with clean water to clear debris.
2. If the screen is damaged, the o-dng kit contains a
replacement in-line filter screen and an o-ring. If

of the lance. 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 lance to the spray gun, as described
earlier in this manual.
Purge Pump of Air and Contaminants
To remove the air from the pump, follow these
steps: .
• Set up the cleaning system as described in the
ASSEMBLY section and connect the water supply.
• Remove the wand extension from the gun.
• Pull the t.riggeron the gun and hold until a steady
stream of water appears.
To remove the contaminants from the pump,
follow these steps:
• Set up the cleaning system as described in the
ASSEMBLY section, and connect the water supply.
• Remove the nozzle attachment from the gun.
• Start the engine according to instructions in
OPERATION section.
Pull the trigger on the gun and hold.
When the water supply is steady and constant,
engage the safety latch and refasten the nozzle

Nozzle Maintenance
If the nozzle becomes restricted or clogged with
foreign materials, such as dirt, excessive pump
pressure may develop. A partially clogged nozzle can
cause a pulsing condition during use. This generally is
not a pump related problem, but rather a clogged or
partially restricted _nozzle.
If the nozzle becomes clogged or partially restricted,
immediately clean the nozzle with the kit included with
your cleaning system by following these instructions:
• ,Shut off the engine and turn off the water supply.
• Separate the wand from the gun.
• Rotate to stream setting.
• Remove nozzle from the end of the wand using a
2mm or 5/64 allen wrench.
• Use the wire included in the kit or a small paper
clip to free the foreign materials clogging or
restricting the nozzle.
