FIG. 11
TURBO NOZZLE

With the adjustable nozzle you can adjust the spray pattern
to be either high pressure or low pressure, You can also
adjust the spray so it is concentrated in a stream pattern or
expanded into a fan pattern. Use this nozzle to apply
detergenL
o
Push tile nozzle attachment forward when you wish to
adjust the spray to low pressure mode (Fig° 13). Push
the nozzle backward to achieve high pressure,
=
Twisting the nozzle adjusts the spray pattern from a
narrow stream to an expanded stream
FIG. 1O
o
You can also adjust the pressure by turning the pressure
control knob (Fig. 14) to the desired pressure setting.
Turning this knob all the way clockwise produces the highest pressure. Do not unscrew the pressure control valve
more than 3 turns. It will come off.
Simply shutting OFF engine will not release pressure in the system. Pull the trigger on the spray wand
assembly to relieve the pressure in the hose_
NOTE: A small amount of water will squirt out when you
release the pressure.
SPRAY NOZZLES
DECREASE PRESSURE
Your high pressure washer comes equipped with an adjustable nozzle (Fig. 11). You can order a turbo nozzle (Fig

To stop flow of detergent, turn knob clockwise or reo
move filter from detergent or set nozzle to high pressure position,
NOTE: Detergents are most effective when applied to a dry
surface.
IMPORTANT:
YOU MUST ATTACH ALL HOSES BEFORE YOU START THE ENGINE STARTING THE ENGINE WITHOUT ALL THE HOSES CONNECTED WILL

PRESSURE WASHING/RINSING
WARNING: BE EXTREMELY CAREFUL IF YOU
MUST USE PRESSURE WASHER FROM LADDER,
SCAFFOLDING OR ANY OTHER RELATIVELY UNSTABLE LOCATION. PRESSURE IN A RUNNING
WASHER BUILDS IN THE WAND AS YOU CLIMB.
WHEN YOU PRESS THE TRIGGER, THE RECOIL
FROM THE INITIAL SPRAY COULD FORCE YOU
TO FALL, OR IF YOU ARE TOO CLOSE TO THE
CLEANING SURFACE, HIGH PRESSURE COULD
FORCE YOU OFF CLIMBING APPARATUS.
Pressure washers are useful cleaning tools designed to
clean almost any surface in two easy steps,
o
The first step involves applying an appropriate detergent/solvent solution to penetrate and loosen grime.
The detergent is applied at low pressure to avoid
splashing, overspraying and waste_ Leave the solution
on surface for 3 to 5 minutes to allow solution to work
=
The second step involves cleaning the surface you
have prepared with the pressure washer and then
rinsing it clean.
To apply detergent follow these steps:

o
Prepare your detergent solution as required by your
job.

BEFORE
STARTING
THE
ENGINE
To operate the engine you will need the following:
ENGINE OIL
IMPORTANT:
ANY ATTEMPT TO CRANK OR START
THE ENGINE BEFORE IT HAS BEEN PROPERLY SERVICED WITH THE RECOMMENDED OIL RESULTS IN AN
ENGINE FAILURE,
A 20 oz, bottle of SAE 30 weight oil is included in the parts
carton,
FIG. 16
11
OPERATION
NOTE: When adding oil to the engine crankcase in the
future, use only high quality detergent oil rated with API
service classification SC, SD, SE, SF, SG rated SAE 30
weight. Use no special additives. Select the oil's viscosity
grade according to your expected operating temperature.

TO SEPARATION AND FORMATION OF ACIDS DURING
STORAGE. ACIDIC GAS CAN DAMAGE THE FUEL SYSTEM OF AN ENGINE WHILE IN STORAGE. TO AVOID
ENGINE PROBLEMS, THE FUEL SYSTEM SHOULD BE
EMPTIED
BEFORE
STORAGE
OF 30 DAYS OR
LONGER. SEE "STORAGE" ON PAGE 17. NEVER USE
ENGINE OR CARBURETOR CLEANER PRODUCTS IN
THE FUEL TANK OR PERMANENT DAMAGE MAY OCCUR.
Although multi-viscosity oils (5W30, 10W30, etc.) improve
starting in cold weather, these multi-viscosity oils will result
in increased oil consumption when used above 32°F.
Check your engine oil level more frequently to avoid possible damage from running low on oil. Oil sump capacity is
21 ounces°
•
Clean area around fuel fill cap, remove cap_
o
Add "UNLEADED"
tank_
regular gasoline, slowly, to fuel
o Install fuel cap and wipe up any spilled gasoline
TO TURN ON WASHER
ADD ENGINE OIL:
CAUTION: ANY ATTEMPT TO CRANK OR START
THE ENGINE BEFORE IT HAS BEEN PROPERLY
SERVICED WITH THE RECOMMENDED
OIL RESULTS IN AN ENGINE FAILURE.
Place pressure washer on a level surface and remove
one of yellow Oil Fill Caps (Fig. 18), insert clean funnel
in opening, and add engine oil from the enclosed bottle
until level is at point of overfiowing. Check engine oil
level before starting each time thereafter. If oil level is
below point of overflowing, fill to proper level
Crankcase oil capacity is about 620ml or 21 fluid ounces.

OPERATION
SENSING LOW OIL PRESSURE
If the system senses low oil pressure during operation, the
engine shuts down, As the system shuts down, the low oil
light comes ON However, once the engine has stopped
rotating, this light will go OFF, See Fig, 22 for schematic,

RESTARTING
RUN
If you try to restart the engine within 5 seconds after it shuts
down, the engine may NOT startr The system needs 5 to
10 seconds to reset.
HALF
If you do restart the engine after such a shutdown and
have not corrected the low oil pressure, the engine
runs for about 10 seconds as described above and then
stops.
FIG. 21
,,
Grasp the starter grip and pull slowly until you feel
resistance_ Then pull rapidly one time.
o
When engine starts, move choke lever to "RUN" position. If engine fails to start, move choke lever to "RUN"
position and pull starter rope (maximum 2 pulls)_
SIPHONING
o
If engine fails to start, repeat the previous two steps.
We recommend that you DO NOT siphon your water supply
from sources other than from connecting to household
water supply.
o
Once engine has started, place the Safety Latch on
spray gun to the OFF position.
TIPS
,,
Press trigger on gun andwand assembly_Water should
spray out the nozzle.
,,
o
Adjust nozzle for correct pressure, spray angle. You
can also rum the pressure control knob to the desired
pressure setting.
Initially clean an area and then check the surface for
damage, If no damage is found, you can assume it is
okay to continue cleaning Detergents work best when
applied to dry surface,
=
For most effective cleaning, keep spray nozzle between 8 to 24 inches of cleaning surface°
o
Allow the detergent to soak in between 3-5 minutes
before washing and dnsing
o
For cleaning, start at lower portion of area to be washed
and work upward, using long, even overlapping
strokes.
-
For rinsing, push nozzle sleeve to high pressure and
wait for detergent to clean Start at top of area to be
rinsed, working down with same action as for cleaning.
o
Your pressure washer is ready to use.
IMPORTANT: AN INTERNAL THERMAL RELIEF VALVE
HAS A MAXIMUM TEMPERATURE SEFrING OF 140°F
(60°C). IF YOU RUN THE PUMP FOR 5 MINUTES WITHOUT PRESSING THE TRIGGER ON THE SPRAY GUN,
1/2 TO 1 OUNCE OF WATER IS RELEASED THROUGH
THE VALVE TO COOL THE UNIT. THE SMALL AMOUNT
OF WATER WILL DRIP OUT THE BOTTOM OF PUMP_
LOW OIL PRESSURE
SHUTDOWN
SYSTEM
o
The engine is equipped with a low oil pressure sensor that
shuts down the engine automatically when the oil pressure
drops below 6 psL If the engine shuts down by itself and
the fuel tank has enough gasoline, check engine oil level
Never use garden hose inlet to siphon detergent or
wax.
o
If you get the spray nozzle too close, especially using
high pressure mode, you may damage the cleaning
surface.
INITIAL START'UP
o
A delay built in the shutdown system allows oil pressure to
build during starting. The delay allows the engine to run for
about 10 seconds before sensing oil pressure.
If you have the spray nozzle too far away, the cleaning
will not be as effective_
o
Do not get closer than 6 inches when cleaning automobile tires.
