Operating Instructions
1. Turn on water supply at the faucet.
2. Make sure the “ON/OFF” switch is in the “OFF”
position. The power switch has international
symbols: On (|) Off (O).
3. Completely unwind the power cord and plug into
a grounded 120 volt outlet.
4. Release the spray gun safety lock (J) on the spray
gun (I). Point the spray gun in a safe direction and
squeeze the trigger until there is a steady stream
of water, releasing water and air out of the hose.
Lock the spray gun.
5. Turn the power switch to the “ON” (|) position.
The unit will run on for 1-2 seconds and shut off.
This is a normal function of the auto-start feature.
6. Begin power washing by squeezing the trigger all
the way into the handle.
7. Release the trigger to stop the power washer.
8. Allow the motor to come to a complete stop
before squeezing the trigger again.
9. Squeezing the trigger rapidly will cause the auto-
start feature to miss an on/off cycle and may
prevent the washer from turning on. Use slow,
deliberate trigger pulls to avoid this.
10. ALWAYS test a small area to avoid damaging the
surface.
Operation Tips
• When using detergent, fill bottle with a properly
formulated detergent-to-water ratio, following
instructions on the container.
• DO NOT use thick, gel-like detergents, as they will
clog the power washer and can cause damage.
• It is normal to hear the motor run intermittently
when the trigger is not being squeezed. The
pump is priming itself to operate when the trigger
is squeezed.
• Turn off the power washer if not being used after
five minutes.
• The O-rings in the hose should be cleaned
regularly and lubricated with non-water soluble
grease such as petroleum jelly.
• Keep the spray tip cleaning wire nearby for
unclogging the tips.
How to Avoid Damaging Surfaces
• Damage to surfaces being cleaned occurs when
the impact force of the water pressure exceeds
the durability of the surface. Bare wood can
be penetrated; paint can be peeled off, etc.
You can vary the force of the power washer by
adjusting:
1. The angle of the nozzle to the surface
being cleaned.
2. The distance from the nozzle to the surface
being cleaned.
• NEVER use a narrow, high-pressure stream of
water on soft surfaces.
• When cleaning windows, it is recommended to
use a minimum of 25
°
spray tip to protect the
glass. A 0
°
spray tip is to concentrated of a spray
and may shatter the window. Position spray tip
at a 45
°
angle, approximately four to five feet
away from the window. Squeeze the trigger and
vary the spray pattern and angle until optimum
cleaning efficiency is achieved.
