Basic Elements of an Engine
Refer to the Engine Owner's Manual for location and
operation of engine controls.
NOTE: The power rating of the engine is the net power
output tested on the production engine for the engine
model and measured in accordance with SAE J1349 at the
rated speed indicated above. Mass production engines
may vary from this value. Actual power output for the
engine installed in the final machine will vary depending
on numerous factors, including the operating speed of
the engine in applications, environmental conditions,
maintenance, and other variables.
Choke Control: Opens and closes carburetor choke valve.
starter grip: Pulling starter grip operates recoil starter to
crank engine.
Engine switch: Enables and disables ignition system.
ASSEMBLY INSTRUCTIONS (FIG. B–E)
1. Locate and remove all loose parts from the carton.
2. Cut four corners of the carton from top to bottom and lay
the panels flat.
3. Slide the handle assembly
holes, insert saddle bolts and secure in place with knobs.
Tighten until snug.
NOTICE: Risk of personal injury. Avoid placing hands
between handle and frame when assembling to
prevent pinching.
4. Remove the colored quick-connect nozzles
plastic bag and insert them into correct grommet on the
nozzle holder. Nozzles are color coded to match colored
nozzles on label

NOTE: The pump on this unit is maintenance free and
requires no oil. If there is a problem with the pump, visit our

NOTICE: The engine is shipped without oil. Before
starting engine, add the oil provided. Damage to the
engine will occur if the engine is run without oil, this
damage will not be covered under warranty.
OPERATION
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.
* Complies with CETA Performance Standard CPC-100.

Bypass Mode: Allows water to re-circulate within the
pump when the gun trigger is not pulled. This feature
allows the operator to release the trigger gun and reposition
themselves without having to turn the engine off in between
cleaning actions.
WARNING: Do not allow the unit to run for more
than two minutes without the gun trigger being
pulled. This could cause overheating and damage
to the pump. When the temperature inside the
pump rises too high, the thermal relief valve will
open and release a spray of water from the pump
to lower the internal temperature. The valve will
then close.
Thermal Relief Valve (Fig. F): When the temperature inside
the pump rises too high, this valve will open and release a
gush of water in an effort to lower the temperature inside
the pump. The valve will then close. NOTE: Thermal relief
valve
location will vary depending on the pump type.

Detergent 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. If your water source is a well,
the garden hose length can only be 30 ft. (9 m) max.
WARNING: To reduce the possibility of
contamination always protect against backflow
when connected to a potable water system.
Pressure Washer Operating Features
Pressure Adjustments
The pressure setting is preset at the factory to achieve op ti-
mum pres sure and cleaning. If you need to lower the pres-
sure, it can be accomplished by these meth ods.
1. Back away from the sur face to be cleaned. The
further away you are, the less the pressure will be on the
surface to be cleaned.
2. Change to the 40˚ nozzle (white). This nozzle delivers
a less powerful stream of water and a wider spray
pattern. Refer to how To Use spray Wand.
NOTICE: DO NOT attempt to increase pump pressure.
A higher pressure setting than the factory set pressure
may damage pump.
How To Use Spray Wand
The nozzles for the spray wand are stored in the nozzle holder on
the panel assembly. Colors on the panel identify nozzle location
and spray pattern. Refer to the following chart to choose the
correct nozzle for the job to be performed. NOTE: Some models
may not include all of the nozzles shown in the chart.

DANGER: Risk of fluid injection. Do not direct
discharge stream toward persons, unprotected
skin, eyes or any pets or animals. Serious injury
will occur.
