OPERATION
When adding gas to the pressure washer, make sure the unit
is sitting on a flat, level surface. If the engine is hot, let the
pressure washer cool before adding gas. ALWAYS fill the
fuel tank outdoors with the machine turned off.
NOTE: This is a 4-cycle engine. DO NOT mix fuel and
lubricant together.

Mix fuel stabilizer with gasoline according to fuel stabilizer
manufacturer’s directions.
 Before removing the fuel cap, clean the area around it.
Remove the fuel cap.
 Insert a clean funnel into the fuel tank then slowly
pour gasoline into the tank. Fill tank to approximately
1-1/2 in. below the top of the tank neck (this allows for
fuel expansion).
 Replace fuel cap and tighten until the cap “clicks”.
 Clean up any spills before starting the engine.
STARTING AND STOPPING THE PRESSURE
WASHER
See Figures 12 - 13.
NOTICE:
Do not run the pressure washer pump without water
supply connected and turned on, as this may damage the
high pressure seals and decrease pump life. Completely
unwind the hose from its reel or coil and make sure the
hose is not being restricted by tires, rocks, or any other
objects that may lessen or prevent water flow to the
pressure washer.
Before starting the engine:

Connect all hoses.
 Check all fluids (lubricant and gas).
 Turn on the garden hose then squeeze the trigger to
relieve air pressure; hold the trigger until a steady stream
of water appears.
NOTE: Make sure the faucet is turned on fully and that
there are no kinks or leaks in the hose.
To start the engine:

Turn the fuel valve to the ON position.
 Pull choke out to the START position.
NOTE: If restarting after a brief stop (i.e., after refueling
or moving), leave the choke lever in the RUN position.
 Put the on/off switch in the ON position.
 Grasp the starter grip and rope and pull slowly until
resistance is felt. Give the starter grip and rope a short,
brisk pull to start the engine.
NOTE: Do not allow the starter grip and rope to snap
back after starting; return it gently to its original place.
 Let engine run for several seconds, then push choke in
to the RUN
position.
To stop the engine:

Put the on/off switch in the OFF position.
 Turn the fuel valve to the OFF position.
 Shut off the water supply and pull trigger to release water
pressure.
WARNING:
While operating and storing, keep at least 3 feet of
clearance on all sides of this product, including overhead.
Allow a minimum of 30 minutes of “cool down” time
before storage. Heat created by muffler and exhaust
gases may be hot enough to cause serious burns and/
or ignite combustible objects.
USING THE SPRAY WAND TRIGGER
See Figure 14.
For greater control and safety, keep both hands on the trigger
handle at all times.

Pull back and hold the trigger to operate the pressure
washer.
 Release the trigger to stop the flow of water through the
nozzle.
To engage the lock out:

Push up on the lock out until it clicks into the slot.
To disengage the lock out:

Push the lock out down and into its original position.
To use the spray wand, start with the nozzle 1-2 ft. away
from the cleaning surface. Carefully approach the surface
just until the desired level of cleaning is achieved. If the spray
is too close it can damage the cleaning surface.
INSTALLING/REMOVING NOZZLE
See Figure 15.
WARNING:
NEVER change nozzles without locking the lock out on
the trigger handle and NEVER point the wand at your
face or at others. The quick-connect feature contains
small springs that could eject the nozzle with some force.
Failure to heed this warning could cause personal injury.
To connect the nozzle to the trigger handle:

Turn off the pressure washer and shut off the water supply.
Pull trigger to release water pressure.
 Engage the lock out on the trigger handle by pushing up
on the lock out until it clicks into the slot.
 Push the nozzle into the quick-connect collar until it clicks
in place and is secured properly.
