PRESSURE WASHER
TERMINOLOGY
PSI: Pounds per Square Inch. The unit
of measure for water pressure. Also
used for air pressure, hydraulic
pressure, etc.
GPM: Gallons Per Minute. The unit of
measure for the flow rate of water.
CU: Cleaning Units. GPM multiplied by
PSI. GPM x PSI = CU
Bypass Mode: Allows water to
re-circulate within pump when the gun
trigger is not pulled.
two minutes without the gun trigger
pulled could cause overheating and
damage to the pump.
Chemical Injection System: Mixes
cleaners or cleaning solvents with the
water to improve cleaning
effectiveness.
Water Supply: All pressure washers
must have a source of water. The
minimum requirements for a water
supply are 20 PSI and 5 gallons per
minute.
HOW TO USE
IMPORTANT: Read and understand
how to use the pressure washer
before operating.
TO ADJUST PRESSURE
The pressure setting is preset at the
factory to achieve optimum pressure
and cleaning. If you need to lower the
pressure, it can be accomplished by
these methods.
1. Back away from the surface to
be cleaned. The further away you
are, the less the pressure will be
on the surface to be cleaned.

2. Rotate the nozzle at the end of
the multi-adjustable spray wand

cleaned.
pressure. A higher pressure setting
than the factory set pressure may
damage pump.
HOW TO USE SPRAY WAND
Your pressure washer is equipped with
a multi-adjustable spray wand with
both high and low pressure settings.
The high pressure setting is for
cleaning and rinsing, the low pressure
setting is for applying chemicals or
cleaning solutions to surfaces.
NOT allow the jet-like spray to come
in contact with unprotected skin,
eyes, or with any pets or animals.
Serious injury can occur.
NOT direct discharge stream toward
persons.
For high pressure operation, pull back
the nozzle of the multi-adjustable
spray wand as shown.
The nozzle at the end of the multi-
adjustable spray wand can be rotated
to change the high pressure spray
pattern from a 0º pencil stream to a
40º fan spray, as shown. Markings
have been placed on the nozzle to
help you select the spray pattern.
