Operate engine only at governed speed. Running
the engine at excessive speeds increases the
hazard of personal injury. Do Not tamper with parts
which may change the governed speed.
Do Not wear loose clothing, jewelry or anything that
may be caught in the starter or other rotating parts.
Before starting the pressure washer in cold weather,
check all parts of the equipment and be sure ice has
not formed there.
Never use a spray gun which does not have a
trigger lock or trigger guard in place and in working
order.
Keep the hose connected to machine or the spray
gun while the system is pressurized. Disconnecting
the hose while the unit is pressurized is dangerous.
Units with broken or missing parts, or without
protective housing or covers, should NEVER be
operated.
Check the fuel system for leaks or signs of
deterioration, such as chafed or spongy hose, loose
or missing clamps, or damaged tank or cap. Correct
all defects before operating the pressure washer.
Do Not spray flammable liquids.
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.
Never aim the spray gun at people, animals or
plants. The high pressure stream of water that this
equipment produces can pierce skin and its
underlying tissues, leading to serious injury and
possible amputation.
Never allow any part of the body to come in contact
with the fluid stream. Do Not come in contact with a
fluid stream created by a leak in the high pressure
hose.
Always wear eye protection when you use this
equipment or when you are in the vicinity where the
equipment is in use.
High pressure spray can cause paint chips or other
particles to become airborne.
Do Not operate the pressure washer above the
rated pressure.
Never move the machine by pulling on the high
pressure hose. Use the handle provided on the unit.
Operate and store this unit on a stable surface.
Always be certain the spray gun, nozzles and

The muffler and engine heat up during operation
and remain hot immediately after shutting it down.
Avoid contact with a hot muffler or engine as you
could be severely burned.
High pressure hose can develop leaks from wear,
kinking, abuse, etc. Water spraying from a leak is
capable of injecting material into skin. Inspect hose
each time before using it. Check all hoses for cuts,
leaks, abrasions or bulging of cover, or damage or
movement of couplings. If any of these conditions
exist, replace hose immediately. Never repair high
pressure hose. Replace it with another hose that
exceeds maximum pressure rating of your unit.
The muffler and air cleaner must be installed and in
good condition before operating the pressure
washer. These components act as spark arresters if
the engine backfires.
In the State of California a spark arrester is required
by law (Section 4442 of the California Public
Resources Code). Other states may have similar laws.
Federal laws apply on federal lands.
NOTE: If you equip the muffler with a spark arrester, it
must be maintained in effective working order. You can

Cleaning and Applying Chemical
WARNING! You must attach all hoses before
you start the engine. Starting the engine without
all the hoses connected and without the water
turned ON will damage the pump.
IMPORTANT: Use soaps designed specifically for
pressure washers. Household detergents could
damage the pump.
To apply detergent follow these steps:
Review the use of the nozzles.
Prepare the detergent solution as required by the
manufacturer.
Place the chemical injection siphon/filter into the
detergent container.
CAUTION! Keep the chemical injection tube
from coming in contact with the hot muffler.
Make sure the black nozzle is installed.
NOTE: Detergent cannot be applied with the high
pressure nozzles (White, Green, Yellow, or Red).
Make sure the garden hose is connected to the
water inlet. Check that the high pressure hose is
connected to the spray gun and the pump and start
the engine.
Apply the detergent to a dry surface, starting at
lower portion of area to be washed and work
upward, using long, even, overlapping strokes. Do
Not allow the detergent to dry on (prevents
streaking).
Allow the detergent to soak in between 35 minutes
before washing and rinsing. Reapply as needed to
prevent surface from drying.
Pressure Washer Rinsing
WARNING! Be extremely careful if you must
use the pressure washer from a ladder,
scaffolding or any other relatively unstable
location. Hose water pressure builds as you
climb. When you press the trigger, the recoil
from the initial spray can be very strong. The
high pressure spray could cause you to fall if
you are too close to the cleaning surface.
After you have applied detergent, scour the surface
and rinse it clean as follows:
Apply safety latch to spray gun.
Remove the black chemical nozzle from the nozzle
extension.
Select and install the desired high pressure nozzle
following the instructions How to Use the Nozzles
on page 9.
Keep the spray gun a safe distance from the area
you plan to spray.
Increase or decrease spray pressure by turning the
pressure control knob counterclockwise or clockwise
respectively (Figure 13). Use lower pressure to
wash items such a as a car or boat. Use higher
pressure to strip paint and degrease driveways.
Apply a high pressure spray to a small area and
then check the surface for damage. If no damage is
found, you can assume it is okay to continue
cleaning.
Start at the top of the area to be rinsed, working
down with same overlapping strokes as you used for
cleaning.
Automatic Cool Down System
(Thermal Relief)
If you run the engine on your pressure washer for
3-5 minutes without pressing the trigger on the spray
gun, circulating water in the pump can reach a
temperature between 140145°F. At this temperature,
the system engages and cools the pump by
discharging the warm water onto the ground. This
system prevents internal damage to the pump.

PRESSURE WASHER
MAINTENANCE
Check and Clean Inlet Screen
Examine the screen on the water inlet. Clean it if the
screen is clogged or replace it if screen is damaged.
Check High Pressure Hose
The high pressure hose can develop leaks from wear,
kinking, or abuse. Inspect the hose each time before
using it. Check for cuts, leaks, abrasions or bulging of
cover, damage or movement of couplings. If any of
these conditions exist, replace the hose immediately.
WARNING: Water spraying from a leak is
capable of injecting material into skin. Inspect
hose each time before using it. Never repair a
high pressure hose. Replace it with another
hose that exceeds the maximum pressure rating
of your pressure washer.
Check Detergent Siphoning Tube
Examine the filter on the detergent tube and clean if
clogged. The tube should fit tightly on the barbed
fitting. Examine the tube for leaks or tears. Replace
the filter or tube if either is damaged.
Cleaning Detergent Siphoning Tube
If you used the detergent siphoning tube, you must
flush it with clean water before stopping the engine.
Place the chemical injection siphon/filter in a bucket
full of clean water.
