Check Chemical Injection Tube
Examine the filter on the detergent hose and clean if
clogged. The tube should fit tightly on the barbed fitting.
Examine the tube for leaks or tears. Replace the filter or
tube if either is damaged.
Purge Pump of Air and
Contaminants
To remove air from the pump, follow these steps:
• Set up the pressure washer as described in “Preparing
the Pressure Washer for Use” on page 5, and connect
the water supply.
• Remove the nozzle extension from the gun.
• Pull the trigger on the gun and hold.
To remove contaminants from the pump, follow
these steps:
• Set up the pressure washer as described in “How to Use
Your Pressure Washer” on page 7, and connect the
water supply.
• Remove the nozzle extension from the gun.
• Start the engine according to instructions given on
page 7.
• Squeeze the trigger on the gun and hold.
• When the water supply is steady and constant, engage
the safety latch and refasten the nozzle extension.
Cleaning Chemical Injection Tube
If you have used the chemical injection tube you must flush
it with clean water before stopping the engine.
• Place the chemical injection tube in a bucket full of clean
water.
• 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 gun to
relieve the pressure in the hose.
Nozzle Maintenance
If a nozzle becomes restricted or clogged with dirt or
foreign materials, a pulsing sensation caused by excessive
pump pressure may occur during use.
Immediately clean a clogged or partially restricted nozzle
with the kit included with your pressure washer by
following these instructions:
• Shut off the engine and turn off the water supply.
• Disengage the safety latch and pull the trigger on the
spray gun. Hold until all water is purged from the unit.
Engage the safety latch on the spray gun.
• Separate the nozzle extension from the spray gun.
• Twist nozzle to stream setting.
• Remove nozzle from the end of the nozzle extension
using a 2 mm or 5/64 allen wrench (included in Nozzle
Cleaning Kit) (Figure 17).
• Use the wire included in the kit or a small paper clip to
free the foreign materials clogging or restricting the
nozzle (Figure 17).
