servicing of a double-
insulated appliance
In a double-insulated product, two
systems of insulation are provided
instead of grounding. No grounding
means are provided for a double-in-
sulated product, nor should ground-
ing means be added to the product.
Servicing a double-insulated product
requires extreme care and knowl-
edge of the system, and should be
done only by qualified service per-
sonnel.
Replacement parts for a double-in-
sulated product must be identical to
the original parts. A double-insulat-
ed product is marked with the words
“Double Insulation” or “Double Insu-
lated”. Product may also be marked
with symbol shown below.
‧ ∙
Never permanently engage the
trigger mechanism on the gun.
‧ ∙
Never operate the machine
without all components prop-
erly connected to the machine
(handle, gun/wand assembly,
nozzle, etc.).
Equipment damage.
‧ ∙ ALWAYS turn water supply “ON”
before turning pressure washer
“ON”. Running the pump dry
causes serious damage. The water
supply pressure must be minimum
20 psi and maximum 145 psi.
‧ ∙
Do not operate the pressure
washer with the inlet water
screen removed. Keep screen
clear of debris and sediment.
‧ ∙
NEVER operate pressure washer
with broken or missing parts.
Check equipment regularly and
repair or replace worn or dam-
aged parts immediately.
‧ ∙
Use only the nozzle supplied
with this machine.
‧ ∙
Never leave the gun unattended
while the machine is running.
‧ ∙
Never attempt to alter factory
settings. Altering factory set-
tings could damage the unit and
will void the warranty.
‧ ∙
Always hold gun and wand firm-
ly when starting and operating
the machine.
‧ ∙
NEVER allow the unit to run with
the trigger release (off) for more
than one (1) minute. This will re-
sult in heat build-up which will
damage the pump.
∙
BEFORE SERVICING, CLEANING,
OR REMOVAL OF ANY PART,
SHUT OFF POWER AND RELIEVE
PRESSURE.
Do not use pressure that exceeds
the operating pressure of any of
the parts (hoses, fittings, etc.) in
the pressurized system. Ensure all
equipment and accessories are rated
to withstand the maximum working
pressure of the unit.
Do not spray electrical apparatus
and wiring.
‧ ∙ Never disconnect the high pressure
discharge hose from the machine
while the system is pressurized. To
depressurize machine, turn power
and water supply off, then press
gun trigger 2 - 3 times.
