• Keep water spray away from electric wiring or fatal electric
shock may result.
Spray contact with electrical wiring can result in
electrocution.
WARNING
• Operate pressure washer ONLY outdoors.
• Use a respirator or mask whenever there is a chance that
vapors may be inhaled.
• Read all instructions with mask so you are certain the mask will
provide the necessary protection against inhaling harmful vapors.
Running engine gives off carbon monoxide, an
odorless, colorless, poison gas.
Some chemicals or detergents may be harmful if
inhaled or ingested, causing severe nausea,
fainting or poisoning.
Breathing carbon monoxide will cause nausea,
fainting or death.
DANGER
• Keep spray nozzle between 8 to 24 inches away from cleaning
surface.
• Operate this unit on a stable surface.
• The cleaning area should have adequate slopes and drainage to
reduce the possibility of a fall due to slippery surfaces.
• Be extremely careful if you must use the pressure washer from
a ladder, scaffolding or any other relatively unstable location.
• Firmly grasp spray gun with both hands when using high
pressure spray to avoid injury if gun kicks back.
Use of pressure washer can create puddles and
slippery surfaces.
High pressure spray could cause you to fall if
you are too close to the cleaning surface.
WARNING
WHEN ADDING FUEL
• Turn pressure washer OFF and let it cool at least 2 minutes
before removing gas cap.
• Fill fuel tank outdoors.
• DO NOT overfill tank.Allow space for fuel expansion.
• Keep fuel away from sparks, open flames, pilot lights, heat, and
other ignition sources.
• DO NOT light a cigarette or smoke.
WHEN OPERATING EQUIPMENT
• DO NOT tip engine or equipment at angle which causes fuel
to spill.
• DO NOT spray flammable liquids.
WHEN TRANSPORTING OR REPAIRING EQUIPMENT
• Transport/repair with fuel tank EMPTY or with fuel shutoff
valve OFF.
WHEN STORING FUEL OR EQUIPMENT WITH FUEL
IN TANK
• Store away from furnaces, stoves, water heaters, clothes
dryers or other appliances that have pilot light or other
ignition source because they can ignite fuel vapors.
Fuel and its vapors are extremely flammable and
explosive.
Fire or explosion can cause severe burns or
death.
WARNING
• NEVER aim spray gun at people, animals or plants.
• DO NOT allow CHILDREN to operate pressure washer.
• NEVER repair high pressure hose. Replace it.
• Keep high pressure hose connected to pump and spray gun
while system is pressurized.
The high pressure stream of water that this
equipment produces can pierce skin and its
underlying tissues, leading to serious injury and
possible amputation.
WARNING

Pressure Washer

If Unit is Equipped with Adjustable
Nozzle
If your pressure washer is equipped with an adjustable nozzle
(Model 01805 (2500 PSI)), adjust the spray pattern and spray
pressure as follows:
1. Slide nozzle forward to obtain low pressure mode
(Figure 18). Slide nozzle backward to achieve high
pressure.
2. Point nozzle towards firm surface and press trigger to
test spray pattern (Figure 19).
3. Twisting nozzle adjusts spray pattern from narrow
pattern to fan pattern (Figure 20).
4. For most effective cleaning, keep spray nozzle from
8 to 24 inches away from cleaning surface.
5. DO NOT get closer than 6 inches when cleaning
automobile tires.
If Unit is Equipped with
Quick-Connect Spray Tips
CAUTION! NEVER exchange nozzles without
locking the safety latch on the trigger.
NOTE: Model 01805 (2500 PSI) is NOT equipped with
quick connect spray tips.
The nozzle extension quick–connect allows the use of
several different spray tips. Each spray tip provides a
different spray pattern.
Follow these instructions to change spray tips:
1. Engage safety latch on spray gun.
2. Pull back collar on quick–connect and pull current
spray tip off.
3. Select desired spray tip:

Cleaning and Applying Chemical
IMPORTANT: Use soaps designed specifically for
pressure washers. Household detergents could damage
the pump.
To apply detergent follow these steps:
1. Review the use of nozzles.
2. Prepare detergent solution as required by manufacturer.
3. Place chemical injection siphon/filter into detergent
container.
CAUTION! Keep the chemical injection tube from
coming in contact with the hot muffler.
4A. For model 01805, slide adjustable nozzle forward to
low pressure mode. Detergent cannot be applied with
nozzle in high pressure position.
4B. For models 01806 and 01936, make sure black spray tip is
installed. Detergent cannot be applied with high pressure
quick-connect spray tips (White,Yellow, or Red).
