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.

 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.

 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 increase or decrease the governed
speed.

 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.

 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

Pressure Washer Rinsing

WARNING! Be extremely careful if you must

use the pressure washer from a ladder,
scaffolding or any other unstable location.
Pressure in a running washer builds as you
climb. When you press the trigger, the initial
spray recoil could cause you to fall. The high
pressure spray could also cause you to fall if
you are too close to the cleaning surface.

For Rinsing:

 Slide nozzle backward to high pressure and wait for

detergent to clear.

 Keep the spray gun a safe distance from the area

you plan to spray.

 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 top of area to be rinsed, working down with

same overlapping strokes as you used for cleaning.

NOTE: You can also stop detergent from flowing by
simply removing siphon from bottle.

Automatic Cool Down System

(also known as 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 140145°F. When the water
reaches this temperature, the automatic cool down
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.

DANGER! 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 Chemical Injection Tube

Examine the filter on the detergent hose 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.

Check Gun and Adjustable Nozzle

Extension

Examine the hose connection to the spray gun and
make sure it is secure. Test the trigger by pressing it
and making sure it springs back into place when you
release it. Put the safety latch in the On position and
test the trigger. You should not be able to press the
trigger.

Check In-Line Filter

Refer to Figure 17 and service the in-line filter if it
becomes clogged, as follows:

1. Detach spray gun and nozzle extension from high
pressure hose. Detach nozzle extension from
spray gun and remove o-ring and screen from
nozzle extension. Flush the screen, spray gun,
and nozzle extension with clean water to clear
debris.

 Shut off the engine.

IMPORTANT: Simply shutting OFF engine will not
release pressure in the system. When the engine has
shut down, squeeze the trigger on the spray gun to
relieve the pressure in the hose.

Nozzle Maintenance

If the adjustable nozzle becomes restricted or clogged
with foreign materials, such as dirt, excessive pump
pressure may develop. If this nozzle becomes partially
clogged, it can cause a pulsing sensation during use.
This generally is not a pump related problem, but
rather a clogged or partially restricted adjustable
nozzle.

Immediately clean a clogged nozzle with the kit
included with your pressure washer by following these
instructions:

 Shut off the engine and turn off the water supply.
 Separate the nozzle extension from the spray gun.
 Adjust the nozzle extension to the stream position.
