f. Allow the Engine to run for several seconds. Then,
if the Choke lever is
in the CHOKE
position, move the
Choke Lever very
slowly to its
RUN position.
note: Moving the Choke
Lever too fast could
stall the engine.
imPORtant: Allow the engine to run at no load
for five minutes with no load after each start-
up so that the engine can stabilize.
3. Move the throttle up to operating speed.
Operating speed is maximum speed (fast or rabbit),
except during operational break-in period.
Break-in Period
1.
Breaking-in the engine will help to ensure
proper equipment and engine operation.
2. The operational break-in period will last
about 3 hours of use. During this period:
• Do not apply a heavy load to the equipment.
• Do not operate the engine at its maximum speed.
3. The maintenance break-in period will last
about 20 hours of use. After this period:
• Change the engine oil.
Under normal operating conditions subsequent
maintenance follows the schedule in the
MAINTENANCE AND SERVICING section.

WaRninG
Do not direct spray from the pressure
washer at a person or an animal. the water
stream could cause serious injury.
CautiOn
use the pressure washer only on surfaces
able to withstand the force of the spray.
1.
Replace the non-vented brass oil plug with
the aluminum Pump Breather Plug before
first use. The Pump Breather Plug must be
used whenever the pressure washer is used.
The brass oil plug (without the breather hole)
should be used for transporting only.
2. Choose the Nozzle that best meets the needs
of the job. Only use the Nozzles on surfaces
capable of withstanding the force of the spray.
Only use the Black nozzle when using pressure
washer detergent. the power of the other
nozzles will propel mist back at the operator
and can embed detergent into the surface.
3. Pull back the quick connect collar and push the
Nozzle onto the end of the Wand. Make sure the
quick connect collar locks the Nozzle in place.
4. Turn the water supply on and hold down the
Trigger to start the stream. Be aware that
when it is first started, the gun will kick.
5. It is best to start at a low pressure setting, and
adjust the pressure upwards. Test spray the
edge of the surface to be cleaned first to make
sure that the stream is not too strong for the
surface. If the stream damages the surface, turn
the Pressure Regulator Knob counterclockwise
to reduce the pressure. Moving further away
from the surface being cleaned will also reduce
the pressure being applied to the surface. If
the stream is still too strong, turn the engine off,
turn the water supply off, discharge the excess
pressure from the gun by squeezing the Trigger,
and change to a lower pressure Nozzle.
6. To increase the pressure, turn the
Pressure Regulator Knob clockwise.
7. Hold the Wand at about a 45° angle when
cleaning; spraying the surface directly could
embed dirt into the surface (especially
with the high pressure Nozzles). Spray at
a distance of about three to five feet.
• Clean vertical and sloped surfaces
from the top down.
• When cleaning horizontal surfaces, occasionally
use the stream to clear the area of excess water.
CautiOn Do not allow the Pressure Washer
to idle without the trigger held down, for
more than two minutes. the water will
heat up and damage the Pressure Washer.
RiSK OF BuRnS! the pump will also expel
very hot water if allowed to idle too long.
8. Hold the Trigger down and move the Wand back
and forth slowly and steadily to pressure wash the
surface. Take special care when spraying surfaces
made of two different materials (brick and mortar,
for example), so as to not damage the softer of
the two materials during pressure washing.
9. If the surface is streaked or uneven at the end
of a job, switch to a Nozzle that has a wider
spray pattern to blend the affected area.
10. When finished; release the Trigger on the
spray handle, turn the engine power switch
to “OFF”, turn the water supply off and
then shut off gas supply to the engine.
11. Squeeze the Trigger to release excess pressure.
12. If Pressure Washer detergent has been
used for the job, run clean water through the
system to eliminate detergent residue.
13. To prevent accidents, turn off the engine and after
the engine has cooled, disconnect its spark plug
wire after use. Drain all water out of the unit.
Clean external parts with clean cloth, then
store the equipment out of children’s reach.
