ADDING GASOLINE TO THE FUEL TANK
See Figure 8.
WARNING:
Gasoline and its vapors are highly flammable and
explosive. To prevent serious personal injury and property
damage, handle gasoline with care. Keep away from
ignition sources, handle outdoors only, do not smoke
while adding fuel, and wipe up spills immediately.
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.
WARNING:
Always shut off engine before fueling. Never add fuel to
a machine with a running or hot engine. Move at least
30 ft. from refueling site before starting engine. Do not
smoke and stay away from open flames and sparks!
Failure to follow these instructions could result in serious
personal injury.
STARTING AND STOPPING THE PRESSURE
WASHER
See Figures 9 - 12.
NOTICE:
Do not run the pressure washer 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.
NOTE: Make sure the pressure washer's water intake
screen is in place and unclogged before connecting
garden hose.
OPERATION
 Check all fluids (oil 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:
 Move the fuel valve to the OPEN position.
 Put the on/off switch in the ON position.
 Move the choke to the START (cold start) position.
NOTE: If restarting after a brief stop (i.e., after refueling
or moving), leave the choke lever in the RUN position.
 Pull the starter grip and rope until the engine runs (a
maximum of 6 times).
NOTE: Do not allow the grip to snap back after starting;
return it gently to its original place.
 Allow the engine to run for 5 seconds, then push the
choke to the RUN position.
To stop the engine:
 Put the on/off switch in the OFF position.
 Move the fuel valve to the CLOSED position.
NOTE: Shutting off the engine will not relieve pressure in the
system. 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. Keep all body parts, clothing, combustible
materials, and hoses away from the muffler. Heat created
by muffler and exhaust gases could be hot enough to
cause serious burns, ignite combustible objects, and/
or damage high pressure hoses that can result in an
injection injury.
USING THE SPRAY WAND TRIGGER
See Figure 13.
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.
