NOTE or NOTICE: Information that
requires special attention.
This pressure washer is equipped
with a micro-switch 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.

• NEVER operate pressure washer
with broken or missing parts.
Check equipment regularly
and repair or replace worn or
damaged parts immediately.

operating the machine.
• NEVER allow the unit to run
with the trigger release (off)
for more than one (1) minute.
Resulting heat buildup will
damage pump.
• Pressure washer is not meant
to pump hot water. NEVER
connect it to a hot water supply
as it will significantly reduce the
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

13. 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. NOTE: The use
of ThIcker detergents, such as
dish soap, will clog the chemical injection system and prevent
the hose by squeezing the trigger 2 - 3 times.

end of garden hose (with water
running) to tip of nozzle pushing water and debris out the
back opening of the lance.

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 clean-
ing 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 praying 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.
1. Before triggering the gun,
adjust the nozzle to a wide fan
pattern.
2. Place the nozzle approximately
4 - 5 fee 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.
Safety:
• Always turn the “ON/OFF”
switch to “OFF” then trigger
gun to release hose pressure
before unplugging the power
cord.
• Risk of equipment damage. Always make sure the “ON/OFF”
switch on the unit is “OFF” and
unit is unplugged prior to storage.
• Risk of Injection. Unit will
start spraying when trigger is
squeezed if “ON/OFF” switch is
in “ON” position. Always point
gun in a safe direction.
• Occasionally the motor may run
for a short time to bring fresh,
cool water into the pump even
if the trigger is released. This
is part of normal operation and
will not damage the unit.
hoW to’S:
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.
