2. PRESSURE WASHER
TERMINOLOGY
Following are the common terms associated
with the use of pressure washers:
PSI: Pounds per square inch-common
unit measure used for water pressure, air
pressure, hydraulic pressure and pounds
of force.
GPM: Gallons per minute (liters per
minute[metric])-common unit measure
used for flow rate of water.
Bypass Mode: In mode, high pressure
pump recirculates water because spray
gun trigger is not squeezed.
Thermal Relief Valve: When in Bypass
Mode: this valve releases a jet of water
to prevent water temperatures from
reaching harmful levels that damage the
pump. Once the water has cooled, the
temperatures from reaching harmful
levels that damage the pump. Once the
water has cooled, the thermal relief valve
will reset itself. DO NOT allow pump to
run without spraying in (In Bypass Mode)
for more than 5 minutes.

pressure nozzle size (White) and
continue changing to the higher nozzle
size until the best work result is
achieved.
The Pressure Washer comes furnished
with five spray nozzles. Each nozzle is
color coded and delivers a specific spray
pattern and pressure for a particular
cleaning job. The size of nozzle
determines the size of the fan spray and
the pressure out of the nozzle.
0° Nozzle –Red: This nozzle delivers
a pinpoint of pressurized water and is
extremely powerful. It covers a small
area of cleaning only, and should only
be directed at surfaces that can
withstand high pressure such as metal
or concrete. DO NOT use this nozzle to
clean wood.

15° Nozzle –Yellow: This nozzle
delivers a powerful 15-degree spray
pattern for intense cleaning of small
areas. This nozzle should only be used
on areas and materials that can
withstand high pressure.
25° Nozzle –Green: This nozzle
delivers a 40-degree spray pattern and
a less powerful stream of water. This
nozzle should only be used on areas that
can withstand pressure from this nozzle.
40° Nozzle –White: This nozzle
delivers a 40-degree spray pattern and
a less powerful stream of water. This
nozzle can cover a wide area and should
be used for most general cleaning Jobs.
Chemical Nozzle –Black: This nozzle
is used to apply special chemicals and
cleaning solutions. This nozzle produces
the weakest pressure stream. The
Pressure Washer nozzles are stored in
receptacles on a panel mounted to the
handle of the washer. Colors on the

amount, the sensor will activate and will
prevent engine start-up or will stop the
running engine.
If pressure washer shuts off and the oil
level is within specifications, check to
see if pressure washer is sitting at an
angle that forces oil to shift.
Place on an even surface to correct this.
If engine fails to start, the oil level may
not be sufficient to deactivate low oil
level sensor. Add oil as described above.
4-3. Adding Fuel
1. Move the pressure OUTSIDE and

Fuel and fuel vapor are extremely flammable
and explosive.
Fuel and fuel vapor are extremely
flammable and explosive. Fire or
explosion from misuse of fuel can
cause severe burns and even death.
Engine
Gasoline fuel can become stale when stored
over 30 days. Stale fuel causes acid and gum
deposits to form in the fuel system or crucial
carburetor parts. To Keep fuel fresh, add the
provided fuel stabilizer tablets to the fuel tank
(read instructions in the back for directions).
Draining gasoline is unnecessary if the fuel
stabilizer is used according to the instructions
that come with it. Run Pressure Washer
engine for a minimum of two minutes, after
stabilizers added to fuel, to allow it to circulate
throughout the engine. The engine fuel can
be stored up to 24 months.
Store gasoline from one season to another
unless it's been treated with fuel stabilizer.
Replace fuel container, if metal, and if it
begins to rust. Rust and dirt and debris can
contaminate fuel supply and components
resulting in poor performance and /or internal
damage to engine. Fuel should be stored in
newer approved plastic storage containers.
