CAUTION:
Do not overfill. Overfilling the crankcase may cause ex-
cessive smoke and engine damage.
OXYGENATED FUELS
DO NOT USE E85 FUEL. IT WILL VOID YOUR WARRANTY.
NOTE: Fuel system damage or performance problems re-
sulting from the use of an oxygenated fuel containing more
than the percentages of oxygenates stated below are not
covered under warranty.
Ethanol. Gasoline containing up to 10% ethanol by volume
(commonly referred to as E10) is acceptable. E85 is not.
ADDING GASOLINE TO THE FUEL TANK
See Figure 12.
WARNING:
Gasoline and its vapors are highly flammable and
explosive. To prevent serious personal injury and prop-
erty 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: Use unleaded gas only. DO NOT mix lubricant with gas.
 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 13 - 15.
CAUTION:
Do not run the pressure washer pump without water sup-
ply 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.
OPERATION
 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.
To start the engine:
 Turn the fuel valve to the ON position.
 Put the engine switch in the ON position.
 Pull choke.
 Grasp the recoil starter and pull slowly until resistance is
felt. Give the recoil starter a short, brisk pull to start the
engine.
NOTE: Do not allow the recoil starter to snap back after
starting; return it gently to its original place.
 Let engine run for several seconds, then push choke in.
To stop the engine:
 Put the engine switch in the OFF position.
 Turn the fuel valve to the OFF position.
USING THE SPRAY WAND TRIGGER
See Figure 16.
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.
For the most effective cleaning, the spray nozzle should be
between 8 in. and 24 in. from the surface to be cleaned. If
the spray is too close it can damage the cleaning surface.
SELECTING THE RIGHT NOZZLE FOR THE
JOB
See Figures 17 - 18.
Each of the nozzles has a different spray pattern. Before
starting any cleaning job, determine the best nozzle for the
job. The following chart offers some general guidelines to
help you choose the best nozzle for your application.
