iMPortant
This pressure washer is equipped
with a microswitch sensitive
to water flow. This Total Stop
System (TSS) senses water flow
in the pump. When the trigger
is released, water stops flowing
through the pump. The TSS then
automatically turns the motor
off to protect the pump from
overheating.

life of the pump.
• NEVER store the pressure
washer outdoors or where it
could freeze. The pump will be
seriously damaged.
• Release trigger when changing
from high to low pressure
modes. Failure to do so could
result in damage.
Keep hose away
from sharp
objects. Bursting hoses may cause
injury. Examine hoses regularly
and replace if damaged. Do not
attempt to mend a damaged hose.
1. Attach swivel adapter to pump
water inlet, if not already
attached. Notice the swivel
adapter is marked with the
words pump and hose. Make

the adapter to the pump water
inlet to prevent damage to the
threads.
2. Attach garden hose to swivel
adapter side marked hose.

directionS for USe
Damage to cleaning surfaces occurs
because the impact force of the
water exceeds the durability of the
surface. You can vary the impact
force by controlling the nozzle’s
fan pattern, the nozzle’s angle
to the cleaning surface, and the
nozzle’s distance from the cleaning
surface. Never use a narrow high
impact stream or a turbo nozzle
on a surface that is susceptible to
damage. Avoid spraying windows
with a narrow high impact stream
or turbo nozzle. Doing so may
break the window. The surest way
to avoid damaging surfaces is to
follow these steps.
2. THIS MUST BE DONE EACH
TIME THE UNIT IS PLUGGED IN
AN OUTLET.
1. Insert lance adapter into the
gun and turn clockwise to
positive stop as shown below.
2. Insert detergent bottle
assembly into lance, push down
and turn clockwise to a positive
stop.
3. Be sure that the power switch is
in the “OFF” position.

1. Before triggering the gun,
adjust the nozzle to a wide fan
pattern.
2. Place the nozzle approximately
4 - 5 feet away from the
cleaning surface. Then hold
the nozzle at a 45° angle to the
cleaning surface. Trigger the
gun.
3. Vary the fan pattern spray
angle and the distance to the
cleaning surface until optimum
cleaning efficiency is achieved
without damaging the surface.
A clogged or partially clogged
nozzle can cause a significant
reduction of water coming out of
the nozzle and cause the unit to
pulsate while spraying.
To clean out the nozzle:
• Turn off the unit.
• Turn off the water supply.
Relieve any pressure trapped
in the hose by squeezing the
trigger 2 - 3 times.
• Separate lance from gun.
• Rotate nozzle to the narrow
stream setting. This opens up
the fan blades.
• Using the included tip cleaner,
or an un-folded paper clip,
insert wire into the nozzle hole
and move back and forth until
debris is dislodged.
• Remove additional debris by
back-flushing water through
the nozzle. To do this, remove
the lance from the gun, place
end of a garden hose (with
water running) to tip of nozzle
pushing water and debris out
the back opening of the lance.
The use of detergents can
dramatically reduce cleaning time
and assist in the removal of difficult
stains. Some detergents have been
customized for pressure washer use
on specific cleaning tasks. These
detergents are approximately as
thick as water. The use of thicker
detergents, such as dish soap, will
clog the chemical injection system
and prevent the application of the
detergent.
The cleaning power of detergents
comes from applying them to a
surface and giving the chemicals
time to break down the dirt and
grime. Detergents work best when
applied at low pressure.

The combination of chemical action
and high pressure rinsing is very
effective. On vertical surfaces,
apply the detergent starting at
the bottom and working your way
upward. This will prevent the
detergent from sliding down and
causing streaks.
High pressure rinsing should also
progress from the bottom to top.
On particularly tough stains, it
may be necessary to use a brush in
combination with detergents and
high pressure rinsing.
1. The lance is affected by
pressure during operation;
therefore hold it firmly with
both hands and point the
nozzle toward the ground.
2. Activate by pulling the trigger
of the gun/spray handle.
3. Adjust the distance to the
cleaning surface, which will
also adjust your pressure of the
nozzle.
4. Spray pattern shape and
intensity can be changed by
twisting the spray adjuster at
the end of the lance. Keep
hands clear of the front of the
lance to prevent injury.
1. Press the ON/OFF switch to
“OFF” on the pressure washer.
2. Disconnect the plug from the
power source.
3. Shut off the water supply.
4. Activate the spray handle to
relieve the machine of pressure.
5. Lock the trigger into the “OFF”
position.
