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
detergent.
• Push the nozzle attachment forward when you wish to
adjust the spray to low pressure mode (Fig. 9). Push
the nozzle backward to achieve high pressure.
FIG. 6
• Twisting the nozzle adjusts the spray pattern from a
narrow stream to an expanded stream.
• You can also adjust the pressure by turning the pres
sure control knob (Fig. 10) to the desired pressure
setting. Turning this knob ali the way clockwise pro
duces the highest pressure. Do not unscrew the pres

OPERATION
TO TURN ON WASHER
• Attach one end of a garden hose to a cold water sou rce.
Water supply should not exceed 140°F (55°C).
• Check that high pressure hose is attached to pump
outlet and that water supply is attached to pump inlet
(plastic fitting).
• Turn ON water,
• Press trigger on gun and wand assembly to force air
from high pressure hose.
• Adjust nozzle for correct pressure, spray angle. You
can also turn the pressure control knob to the desired
pressure setting.
• Start engine according to “TO START ENGINE."
TO START ENGINE
IMPORTANT: DO NOT RUN PUMP WITHOUT THE
WATER SUPPLY CONNECTED. DO NOT ALLOW PUMP
TO RUN FOR MORE THAN 5 MINUTES WITHOUT
PRESSING THE TRIGGER ON THE GUN. IF NOT IN
USE FOR MORE THAN 5 MINUTES WITHOUT PULLING
THE TRIGGER, RELIEVE PRESSURE AND SHUT OFF
THE UNIT. YOU MUST FOLLOW THIS CAUTION OR
THE PUMP WILL BE DAMAGED.
• Press trigger on pres
sure washer wand to
relieve high pressure
and/or purge the inlet
hose of air.
• Adjust safety latch to
the ON position. This
disables the trigger so
you cannot in
advertantly actuate a

FIG. 14
FIG. IS FIG. 16
• Press trigger on gun and wand assembly. Water
should spray out the nozzle.
• Your pressure washer Is ready to use,,
SIPHONING
We do not recommend that you siphon your water supply
from sources other than from connecting to household
water supply for the following reasons;
• The pump's lifting capability is only a 3-foot maximum
vertical height
• You need an extra intake water filter
• You need to use a rigid intake hose {it cannot collapse),
• Intake water cannot contain any mixture of detergent
or chemicals. This could affect the life of the pump.
TIPS
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 be
tween 8 to 24 inches of cleaning surface.
Allow the detergent to soak in between 3-5 minutes
before washing and rinsing.
For cleaning, start at lower portion of area to be washed
and work upward, using long, even overlapping
strokes.
For rinsing, push the nozzle sleeve to high pressure
and wait for detergent to clear. Start at the top of area
to be rinsed, working down with the same action as for
cleaning.
Never use the garden hose inlet to siphon detergent or
wax.
If you get the spray nozzle too dose, especially using
high pressure mode, you may damage the cleaning
surface.
If you have the spray nozzle too far away, the cleaning
will not be as effective.
Do not get closer than 6 inches when cleaning automo
bile tires.
