NOZZLE REVIEW
Various nozzles may be quick-connected into the end of the wand to
change the spray pattern or use the detergent feature. When using Quick
Connects (Q.C.), be certain the connection is securely locked. If not, the
high pressure water may shoot the nozzle from the wand, causing severe
injury or serious damage. To determine spray fan, refer to the actual num-
ber stamped on the nozzle. The first two digits indicate the spray fan in
degrees, i.e.; 00=0”, 15=15°, 40=40°.
1. The 0° nozzle (RED): This is a blasting nozzle. It delivers a very con-
centrated stream of water. Be cautious when using the straight narrow
stream. It is not recommended for use on painted or wood surfaces,
or items attached with adhesive backings. Uses: Removing weeds
from sidewalk cracks, stubborn stains from concrete, masonry, alumi-
num and steel, caked mud from equipment, and cleaning lawn mower
undersides.
2. The 15° nozzle (YELLOW): This is a chiseling nozzle. The spray should
be directed at a 45° angle to the surface and used like a scraper to
remove paint, grease and dirt. Uses: Surface preparation (removing
mildew stains and paint chips).
3. The 40° nozzle (WHITE): This is a wash nozzle. This wide spray pattern
disperses the water pressure over a large area and is recommended
for moderate washing. Uses: Washing aluminum siding, cleaning win-
dows, washing vehicles, spraying sidewalks, driveways, and patios.

To ensure the water temperature does not exceed acceptable levels, never
allow the pressure washer to operate in the bypass mode (with the unit
running and the trigger closed) for more than three minutes.
A thermal relief valve has been added to this unit to protect the pump. This
valve will open and release water if the water temperature in the pump has
exceeded 140° F. This will allow fresh, cool water to enter the system,
therefore preventing premature failure of pump packings.
PRE-START INSPECTION PROCEDURES:
Before starting the unit, perform the following procedures:
1. Inspect the electrical cords for cuts. If a cut is found, DO NOT TOUCH OR
USE CORD! Replace cord before starting unit.
2. Check the oil level in the pump.
3. Inspect the water inlet strainer. Clean or replace if necessary. See “Water
Supply”, #2.
4. Check all hose connections to ensure they are securely tightened.
5. Inspect for system water leaks, oil leaks and fuel leaks. If a fuel leak is
found, DO NOT START UNIT! See “Risk of Explosion or Fire”, pg. 5. Be
sure that all damaged parts are replaced and that the mechanical problems
are corrected prior to operation of the unit. If you require service, contact
Customer Service.
6. Inspect high pressure hoses for kinking, cuts and leaks. If a cut or leak
is found, DO NOT USE HOSE! Replace hose before starting unit. See
“Risk of Injection or Severe Cutting Injury”, pg. 6. Be sure that all damaged
parts are replaced and that the mechanical problems are corrected prior to
operation of the unit. If you require service, contact Customer Service.

THERMAL RELIEF VALVE
To ensure the water temperature does not exceed acceptable levels,
never allow the pressure washer to operate in the bypass mode (with the
unit running and the trigger closed) for more than three minutes.
A “thermal relief valve” has been added to this unit to protect the pump.
It may begin to open and release water if the water temperature in the
pump has exceeded 140° F. This will allow fresh, cool water to enter the
system.

Operating Instructions
PRIMING THE PUMP
It is essential to prime the pump and flush the unit each time the water
supply has been disconnected from the unit OR whenever the unit has
set for any period of time. This unit has a steel coil which, after setting,
will cause the water remaining in the coil from the previous usage to
turn brown or black. This contaminated water must be flushed from the
system before start-up. This procedure should be performed without the
high pressure hose, gun and nozzle assembly installed.
1. Turn on the water supply.
2. Low pressure water will begin flowing from the water outlet. This al-
lows the unit to prime and purge any air from the system. The unit is
primed when water flow is uninterrupted by air.
3. Once the system is flushed, turn off the water supply and connect the
high pressure discharge hose/gun to the water outlet of the unit.
4. Turn on the water supply.
CAUTION
BE CERTAIN THE HOSE, GUN & LANCE ASSY. ARE NOT
CONNECTED TO THE UNIT WHILE PRIMING THE PUMP. PRIMING
ALLOWS MINERAL DEPOSITS TO BE RELEASED FROM THE
SYSTEM WHICH WOULD OBSTRUCT OR DAMAGE THE GUN
AND NOZZLE ASSEMBLY RESULTING IN COSTLY REPAIRS.
START-UP/COLD WATER OPERATION
WARNING
KEEP CLEAR OF NOZZLE! NEVER PLACE HAND OR FINGERS IN
FRONT OF NOZZLE!
DO NOT DIRECT DISCHARGE STREAM AT PEOPLE OR PETS!
CAUTION
DO NOT ALLOW SPRAY PATTERN TO REMAIN ON A FIXED AREA
FOR AN EXTENDED PERIOD OF TIME. POSSIBLE DAMAGE MAY
OCCUR TO THE AREA.

operation
1. Refer to the “Safety Precautions” pgs. 7-11 before starting the unit.
2. Locate the Safety Decals on your unit and heed their warnings.
3. Ensure that the switch is in the “OFF” position.
4. Perform the following engine start-up procedures.
a. Point the trigger gun in a safe direction, disengage the safety lock
on the gun and squeeze the trigger.
b. Brace yourself for kickback from the high pressure created by the
pump once the engine has started.
c. Hold the trigger gun open while starting the engine according to the
manufacturer’s instructions in the engine manual accompanying this
unit.
5. Once the unit has started, perform the following procedures with the
gun open:
a. Inspect for system water leaks, oil leaks and fuel leaks. If a fuel leak
is found, TURN UNIT OFF IMMEDIATELY! See “Risk of Explosion
or Fire”, pg. 7. Be sure that all damaged parts are replaced and that
the mechanical problems are corrected prior to operation of the
unit. If you require service, contact Customer Service.
b. Inspect high pressure hoses for kinking, cuts and leaks. If a cut or
leak is found, DO NOT TOUCH HOSE AT LEAK!!! TURN UNIT OFF
IMMEDIATELY! Replace hose before starting the unit. See “Risk of
Injection or Severe Cutting Injury” pg. 8. Be sure that all damaged
parts are replaced and that the mechanical problems are corrected
prior to operation of the unit. If you require service, contact Cus-
tomer Service.
6. Trigger the gun several times and try adjusting the water pressure by
rotating the grip on the lance. NEVER place hand or fingers in front of
the nozzle or look directly into the nozzle! High pressure water creates
a risk of severe injury!
7. Do not allow unit to operate in bypass mode (with trigger closed) for
more than three minutes without triggering the gun. Failure to follow
this simple rule can cause premature failure of pump packings, result-
ing in costly pump repair.
8. Your pressure washer can deliver high pressure spray and a variety
of spray patterns using cold water. If you wish to use the Hot Water,
Steam application or Cleaning with Detergents, for the correct proce-
dures.
