• 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.

• Never operate units with broken or missing parts, or
without protective housing or covers.

• 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 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

remain hot immediately after shutting it down. Avoid
contact with a hot muffler or engine as you could be
severely burned.

• Operate and store this unit on a stable surface.

• 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 meets 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 arrestor 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 arrestor, 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 3–5 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 force
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 8.

• Release the safety latch on the spray gun.

• 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 12). 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 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.

GENERAL MAINTENANCE

RECOMMENDATIONS

The pressure washer warranty does not cover items that
have been subjected to operator abuse or negligence. To
receive full value from the warranty, the operator must
maintain the high pressure washer as instructed in this
manual.

• Some adjustments will need to be made periodically to
properly maintain your high pressure washer.

• All maintenance in this manual and the engine owner’s
manual should be made at least once each season.

• Once a year you should clean or replace the spark plug,
clean or replace the air filter and check the gun and
nozzle extension assembly for wear. A new spark plug
and clean air filter assure proper fuel-air mixture and
help your engine run better and last longer. Please refer
to your engine owner’s manual for more details.

BEFORE EACH USE

• Check engine oil level.

• Check water inlet screen for damage.

• Check in-line filter for damage.

• Check high pressure hose for leaks.

• Check detergent siphoning tube and filter for damage.

• Check gun, nozzle extension, and nozzles for leaks.

• Rinse out garden hose to flush out debris.

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
meets 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.

• Attach the black low pressure nozzle.

• Flush for 1-2 minutes.

• 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 gun to
relieve the pressure in the hose.

Check Gun and Nozzle Extension

Examine the hose connection to the 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 13 and service the in-line filter if it
becomes clogged, as follows:

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

2. If the screen is damaged, the o-ring kit contains a
replacement in-line filter screen and an o-ring. If
undamaged, reuse screen.

3. Place the in-line filter screen into the threaded end of
the nozzle extension. Direction does not matter. Push
the screen in with the eraser end of a pencil until it
rests flat at the bottom of the opening. Take care to
not bend the screen.

4. Place the o-ring into the recess. Push the o-ring snugly
against the in-line filter screen.

5. Assemble the nozzle extension to the spray gun, as
described earlier in this manual.

generally is not a pump related problem, but rather a
clogged or partially restricted nozzle.

If a nozzle become clogged or partially restricted,
immediately clean it with the kit included with your
pressure washer by following these instructions:

• Shut off the engine and turn off the water supply.

• Remove the nozzle from the end of the nozzle
extension.

• Use the wire included in the kit or a small paper clip to
free the foreign materials clogging or restricting the
nozzle (Figure 14).

• Remove additional debris by rinsing out the nozzle. Rinse
between 30 to 60 seconds.

• Reinstall the nozzle into the nozzle extension.

• Reconnect the water supply, turn on the water, and start
the engine.

properly maintain the engine.

PREPARING THE UNIT

FOR STORAGE

Water should not remain in the unit for long periods of
time. Sediments or minerals can deposit on pump parts and
“freeze” pump action. If you do not plan to use the
pressure washer for more than 30 days, follow this
procedure:

1. Flush detergent siphoning tube by placing the filter into
a pail of clean water while running pressure washer in
low pressure mode (adjustable nozzle in the forward
position). Flush for one to two minutes.

2. Shut off the engine and let it cool, then remove all
hoses. Disconnect spark plug wire from spark plug.

3. Empty the pump of all pumped liquids by pulling the
recoil handle about 6 times. This should remove most
of the liquid in the pump.

NOTE: To protect the unit from freezing temperatures,
draw RV antifreeze (non-alcohol) into the pump by pouring
the solution into a 3-foot section of garden hose connected
to inlet adapter and pulling recoil handle twice.

4. Store unit in a clean, dry area.

considered a commercial use pressure washer for the purposes of this warranty.

During said warranty period, the COMPANY will, at its option, repair or replace any part which, upon examination by the
