INTRODUCTION

Dear Customer,

Congratulations on your choice to buy a Husqvarna product! Husqvarna is based on a tradition
that dates back to 1689, when the Swedish King Charles XI ordered the construction of a factory
on the banks of the Husqvarna River, for production of muskets. The location was logical, since
waterpower was harnessed from the Husqvarna River to create the water-powered plant. During
the more than 300 years of being, the Husqvarna factory has produced a lot of different products,
from wood stoves to modern kitchen appliances, sewing machines, bicycles, motorcycles, etc. In
1956, the first motor driven lawn mowers appeared, followed by chain saws in 1959, and it is
within this area Husqvarna is working today.

Today, Husqvarna is one of the leading manufacturers in the world of forest and garden products,
with quality as our highest priority. The business concept is to develop, manufacture and market
motor driven products for forestry and gardening, as well as for the building and construction
industry. Husqvarna’s aim is also to be in the front edge according to ergonomics, usability, security
and environmental protection. That is the reason why we have developed many different features
to provide our products within these areas.

We are convinced that you will appreciate, with great satisfaction, the quality and performance of
our product for a very long time to come. The purchase of one of our products gives you access to
professional help with repairs and service whenever this may be necessary. If the retailer who sells
your machine is not one of our authorized dealers, ask for the address of your nearest service
workshop.

It is our wish that you will be satisfied with your product and that it will be your companion for a
long time. Think of this operator’s manual as a valuable document. By following its’ content (using,
service, maintenance, etc) the life span and the second-hand value of the machine can be
extended. If you will sell this machine, make sure that the buyer will get the operator’s manual.

FREQUENTLY ASKED QUESTIONS

How do I start my pressure
washer?

1. Make sure you have gas and oil in the engine.

2. Turn the water on, then squeeze the trigger on
the gun to make sure the water will flow
smoothly out of the nozzle or tip.

3. Put the engine throttle control in the
“Fast/Start” position. Set the fuel valve to “ON”
Set the On/Off switch to “ON” (if applicable).

4. Close the choke.

5. Squeeze and hold the trigger (to relieve any
back pressure in the pump) while pulling the
starter cord.

6. If the engine does not start after three tries, see
Troubleshooting Section (Pages 20-21).

What type of oil do I use?

ENGINE

THE ENGINE DOES NOT COME FILLED WITH OIL. For
engine oil types and quantities refer to Pages 16
and 19 of this manual and also refer to the included
engine owner’s manual for oil changing instructions.

PUMP

See Page 17 for pump oil types and quantities.
Please note the 5525PW model has a pump that is
sealed and does not require service.

Why don’t I have any water
pressure?

• Is the water hose attached to the pressure
washer?

• Is the water turned on?

• Check for any kinks, leaks, or blockage in the
hoses, fittings, or the nozzle.

• Is the inlet filter screen free of debris? Check and
remove debris if needed.

• Is the quick connect tip in place? (See Page 9.)

How do I get high pressure?

• Use any color tip except black. The black tip is
only used for low pressure detergent application.

How do I get the soap
suction to work?

For Detergent Tanks:

1. Attach clear plastic tube to plastic barb on
detergent tank (see Figure 2).

2. Fill detergent tank with detergent formulated
for use with pressure washers.

3. Install the black spray tip to apply low pressure
detergent.

For Other Units:

1. Attach clear plastic tube to brass barb on pump
(see Figure 2).

2. Put the other filter end of the clear tube into
the detergent container.

3. Install the black spray tip to apply low pressure
detergent.

Why doesn’t the pressure
washer apply detergents
with high pressure?

The reason you don’t apply detergents with high
pressure is that the detergents “bounce” off the
cleaning surface as fast as you apply them.
Detergent is only effective when you allow it time
to work on the surface of whatever you are
cleaning. You can only apply detergent at low
pressure, wait 1-3 minutes to allow it to work, and
rinse the surface with high pressure.

What maintenance do I
need to perform on my
pressure washer?

1. After turning off the pressure washer and the
water, depressurize the hose by triggering the
gun.

2. Remove the garden hose and high pressure hose
from the pump.

3. Pull the start rope slowly five times to purge
water from the pump. This will help protect the
pump from damage.

4. DO NOT store your pressure washer in an area
where the temperature will drop below 32˚F /
0˚C) unless pressure washer is properly
winterized (see Page 15).

Where can I buy accessories
for my pressure washer?

• Call your local Husqvarna Dealer.

OPERATION

1. Surface Preparation

ALWAYS engage the trigger safety latch when unit
is not in use. The following cleaning procedure will
help you organize your cleaning task and ensures
that you will achieve the best results in the shortest
amount of time. Remember to use the spraying /
cleaning techniques mentioned in the following
section.

Before starting a pressure washer cleaning job,
prepare the surface you intend to clean. Clear
furniture from the area and make sure that all
windows and doors are closed tightly. Also, protect
all plants and trees near the cleaning area with a
drop cloth. A covering ensures that your plants
won’t be sprayed by the detergents.

2. Start Up

ALWAYS use this start up procedure to ensure that
the unit is started safely and properly.

If water has frozen in the

pressure washer, thaw the
pressure washer in a warm room before starting. DO
NOT pour hot water on or into the pump; internal
parts will be damaged.

1. Check engine oil levels. Add oil as necessary.

NOTE: Some units are equipped with a low oil
sensor that shuts the engine off if the oil level falls
below a certain level. If the unit stops unexpectedly,
check both the oil and fuel levels. Check the oil
level each time you refuel the unit.

2. Check fuel level. Add unleaded gasoline (rated

86 octane or higher) as required.

DO NOT refuel a

hot engine.
Refueling a hot engine could cause a
fire. Use only fresh, clean unleaded
gasoline. Close the fuel shutoff valve
during refueling.

3. Attach a garden hose to the inlet connection for

garden hose and connect it to the water supply.
Use a hose with a minimum inside diameter of
5/8” (.016 m) and a length of 50 ft. (15 m) or
less.

Some local plumbing codes

require backflow prevention
when connecting to a fresh water supply. Install a
backflow preventer upstream from the pump if
necessary.

a. If inlet water pressure is over 100 psi, install a

regulating water valve at the garden hose
connection.

b. DO NOT exceed 100˚ F (38˚ C) inlet water

temperature.

NOTE: The inlet water supply must have a
minimum flow rate of 8 gpm (30 lpm) or 5 gpm
(191 lpm) on 5525PW.

4. Turn the water supply ON.

NEVER run the unit dry. Be sure
the water supply is completely

turned on before operating the unit.

5. Squeeze the gun until water sprays from the tip
indicating that all air is purged from the system.
Set the trigger safety latch.

6. On model 5525PW: Honda GC Engine:

Open the fuel shutoff valve by turning the knob
counterclockwise until it stops. Close the choke
(if engine is cold) by pulling the choke lever out.
The throttle is fixed.

On model 1340PW, 6027PW, and 9032PW:
Honda GX engine:

Open the fuel shutoff valve by pushing the lever
to the right. Close the choke (if the engine is
cold) by moving the choke lever fully to the left.
The throttle is fixed. Turn the On/Off switch to
the "ON" position.

7. Start the engine:

If the engine is cold, completely close the
engine choke.

If the engine is warm, leave the choke open or
just partially closed. Unlock the trigger safety
latch on the gun. Grasp the starter rope and
brace one foot on the chassis. While squeezing
the trigger on the gun, pull the starter rope
rapidly and firmly. Continue holding the rope as
it returns. Repeat these steps until the engine
starts. In cool weather, the choke may have to
be kept closed for 10 to 30 seconds to keep the
engine running. Otherwise, open the choke as
soon as the engine starts.

When pulling the starter rope,
make sure to keep your hand

and arm clear of the engine and cart components.

NEVER let the starter rope
return by itself. Doing so could

jam the recoil system.

3. Initial High Pressure Rinse

After the engine starts, trigger the gun 3 to 5 times
to get any trapped air out of the system. After the
spray becomes constant, you may need to adjust
the pressure (see pages 13 and 14 for cleaning
techniques).

OPERATION

PRESSURE ADJUSTMENT

Models 9032PW and 1340PW have a pressure
adjustment knob located on the pump (see Figure

10). Turn the knob clockwise to increase the
pressure. Turn the knob counter clockwise to
decrease the pressure. DO NOT try and force the
knob to turn. The knob may already be at either
the lowest or highest setting.

If there is not a plastic adjustment knob located on
the pump (See Figure 10), then the pressure cannot
be adjusted. The only way to adjust the pressure is
to move closer or further away from the cleaning
surface and adjust the spray fan angle as shown in
the next section.

ADJUSTING THE SPRAY FAN ANGLE

Your unit has quick connect tips that have a range
of spray fan angles. Model 5525PW includes the
black detergent and yellow 15° quick connect tips
only.

The quick connect tips can be switched out from a
0° narrow high impact stream to a 65° wide fan
spray.

A narrow stream has high impact force on the
cleaning surface and results in maximum deep
cleaning in a concentrated area. However, this
narrow high impact spray can damage some
surfaces, so use it cautiously. Not recommended for
use on automotive paint, trim and vinyl siding.

A wide fan pattern will distribute the impact of the
water over a larger area resulting in excellent
cleaning action with reduced risk of surface
damage. Clean large surface areas quickly using a
wide fan pattern.

ANGLE TO THE CLEANING SURFACE

When spraying water against a surface, you can
generate maximum impact by striking the surface
head on. However, this type of impact can cause
dirt particles to embed in the surface and can
prevent the desired cleaning action.

Yellow – 15° – Heavy Duty
Green – 25° – General Duty
White – 40° – Light Duty
Black – 65° – Low Pressure Detergent

English — 13

OPERATION

Spray water against a surface at a 45 degree angle
to achieve the most beneficial impact force and to
efficiently remove debris.

DISTANCE FROM CLEANING SURFACE

The distance between the spray nozzle and the
cleaning surface is another factor that affects the
impact force of the water. The impact force of the
water increases as the nozzle is moved closer to the
surface.

HOW TO AVOID DAMAGING SURFACES

Damage to cleaning surfaces occurs because the
impact force of the water exceeds the durability of
the surface. You can vary the impact force by
controlling the spray tip angle to the cleaning
surface and the distance from the cleaning surface
and by changing the spray tip. NEVER use a narrow
high impact stream on a surface that is susceptible
to damage. Avoid spraying windows with a narrow
high impact stream. Doing so may break the
window. The most sure way to avoid damaging
surfaces is to follow these steps:

1. Before triggering the gun, make sure the quick
connect tip you are using is appropriate for the
application.

2. Place the spray tip approximately 4-5 feet (1,22­1,52 m) away from the cleaning surface. Then
hold the lance and spray tip at a 45 degree
angle to the cleaning surface. Trigger the gun.

Figure 14 - Optimum angle to cleaning surface

The color of the tip shows what spray angle it is:

Red – 0° – Maximum Duty
Yellow – 15° – Heavy Duty
Green – 25° – General Duty
White – 40° – Light Duty
Black – 65° – Low Pressure Detergent

3. Vary the fan pattern spray angle and the
distance to the cleaning surface until optimum
cleaning efficiency is achieved without
damaging the surface.

4. Detergent Application

NOTE: Use only detergents formulated for pressure

washers.

NOTE: Test detergent in an inconspicuous area
before use.

NEVER replace quick connect tip
when gun is triggered.

DETERGENTS

The use of detergents can dramatically reduce
cleaning time and assist in the removal of difficult
stains. Many detergents are customized for pressure
washer use on specific cleaning tasks. Pressure
washer detergents are as thick as water. Using
thicker detergents – like dish soap – will clog the
chemical injection system and prevent the
application of the detergent.

Once applied to a cleaning surface, detergents take
time to break down dirt and grime. Detergents
work best when applied at low pressure.

You can effectively clean surfaces by combining the
chemical action of detergents with high pressure
rinses. On vertical surfaces, apply the detergent
starting at the bottom and work your way upward.
This method prevents the detergent from sliding
down and causing streaks. Begin high pressure
rinsing at the bottom and work your way upward.
On particularly tough stains, use a brush in
combination with detergents and high pressure
rinsing.

1. Follow manufacturer’s label directions for mixing
correct concentrations of soap/detergents. The
soap detergent to water ratio through the pump
is approximately 10% (1 to 10).

OPERATION

GENERAL CLEANING TIPS

1. Apply the detergent so that it thoroughly covers
the cleaning surface. Apply the detergent from
bottom to top to prevent the detergent from
sliding down and streaking. Wait a couple of
minutes for the detergent to break down the
dirt and grime. Use a brush to lightly scrub
heavily soiled areas. NEVER allow the detergent
to dry on the cleaning surface.

2. Replace black 65° quick connect tip with another
color tip.

NEVER replace quick connect tip
when gun is triggered.

3. After using detergents, flush the suction system
by placing the detergent suction tube into a
bucket of clean water.

5. Cleaning Power

The easiest way to regulate the cleaning power of
your pressure washer is by changing the distance
from the surface you are cleaning. Begin spraying
with a wide fan pattern while standing several feet
from the surface. Slowly move closer to the object
you are cleaning, adjusting the spray pattern as
necessary, until you find the most effective cleaning
technique.

NOTE: Some units also may have a pressure
adjustment knob on the pump that can adjust the
pressure (models 9032PW and 1340PW).

6. Final Rinse

The final rinse should start at the bottom and work
upward. Make sure that you thoroughly rinse the
surface and that you remove all detergent.

7. Shutdown

1. Be sure all detergent is flushed from system.

2. Turn the engine OFF.

3 Turn the water supply OFF.

4. After the engine and water supply are turned
OFF, trigger the gun to depressurize the system.

NEVER turn the water supply

off before turning the
engine/motor off. Serious damage could occur to the
pump and/or engine/motor.

NEVER disconnect the high

pressure discharge hose from
the machine while the system is pressurized. To
depressurize, turn engine/motor off, turn water
supply off and squeeze gun trigger 2-3 times.

5. After each use, when engine has cooled, wipe all
surfaces of the pressure washer with a clean,
damp cloth.

• DO NOT store the pressure washer outdoors.

• DO NOT store the pressure washer where it
might freeze unless it has been properly
winterized.

8. Storage

LONG TERM STORAGE INSTRUCTIONS (MORE
THAN 30 DAYS IN STORAGE)

1. Remove fuel from the tank and run the pressure
washer in a normal operating mode until the
engine stops from a lack of fuel. Normal
operating mode means actually spraying water
from the gun while the engine is running.

Alternate method – Add fuel stabilizer to gas in
the tank and run in normal operating mode for
at least five minutes.

2. Stop the engine, turn off the water supply, and
trigger the gun to release pressure in the high­pressure hose.

PRESSURE RELIEF

PROCEDURE

To reduce the risk of bodily injury or property
damage, ALWAYS follow this procedure
whenever spraying is stopped, when work is
completed, and before checking or repairing
any part of the system.

1. Engage the trigger safety latch.

2. Turn the unit off.

3. Shut off the water supply.

4. Disengage the trigger safety latch and
trigger the gun to relieve pressure.

5. Re-engage the trigger safety latch.

6. Before overnight storage, long term
storage, or transporting unit, disconnect
the water supply and turn off the fuel
supply valve.

OPERATION

3. Disconnect the water supply and high pressure hose
from the pump.

4. Allow the engine to cool.

5. Disconnect the spark plug wire and remove the
spark plug.

6. Pour 1/2 oz. of engine oil into the spark plug hole.

NEVER pull the

starter rope on the
engine when the spark plug is removed
unless the spark plug hole is covered.
Fuel vapor from the hole can ignite by a
spark.

7. Place a rag over the spark plug hole and slowly pull

the starter rope several times to distribute the oil.

8. Disconnect the high pressure hose from the pump.

9. Insert a 12” to 14” piece of garden hose into the

pump inlet.

10. Place a funnel in the other end of the garden hose.

Read the manufacturer’s

instructions for safe handling
and disposal of RV antifreeze.

11. Pour approximately 6 oz. of RV antifreeze into

the funnel.

12. Pull the starter rope several times until the RV

antifreeze comes out of the pump outlet.

13. Disconnect the high pressure hose from the gun

and drain the hose. Hold the gun and lance in a
vertical position and squeeze the trigger to
drain the water.

Never store the pressure washer

with gasoline in the tank inside
a building where fumes may reach an open flame or
spark. Allow the engine to cool before storing in
any enclosure.

NOTE: To winterize unit, please follow the same
intructions for Storage.

TIPS FOR EXTENDING THE LIFE OF YOUR PRESSURE
WASHER

• NEVER operate the unit without water.

• Your pressure washer is not meant to pump hot

water. NEVER connect your pressure washer to a
hot water supply as it will significantly reduce
the life of the pump.

• Running the unit for more than two minutes

without spraying water causes heat to build up
in the pump. Running the unit without spraying
water can damage pump components.

• Release the trigger prior to switching the lance

between high and low pressure. Failure to do so
may reduce the life of the o-rings in the lance.

maximum performance and life from the pressure
washer. Refer to the schedule for recommended
maintenance. If you operate the pressure washer in
dusty conditions, perform maintenance checks more
often.

ENGINE OIL CHANGING INSTRUCTIONS

Before tipping the engine or
equipment to drain oil, drain fuel

from the fuel tank.

NOTE: Change oil while the engine is cool.

1. Disconnect the spark plug wire from the spark
plug.

2. Locate and remove the engine oil drain plug (see
Figure 18).

3. Drain old oil.

4. Replace the drain plug and set the unit upright.

MAINTENANCE

CHECKING PUMP OIL AND PUMP OIL CHANGING

Checking oil level: Most pumps have either a sight

glass or a dipstick (or both) to check the pump oil
level. The correct oil level is at the center of the
sight glass (center of red dot). The sight glass is
usually located on the back side of the pump [See
Figure 19 (B)].

For model 5525PW: Pump is factory sealed.
Changing or refilling the oil in the pump requires
removal of the pump from the engine and should
not be required unless oil has leaked out due to
worn or damaged oil seals in the pump. If oil has
leaked out of the pump, bring the pressure washer
to a certified service center for repair.

For models 6027PW, 9032PW, and 1340PW: These units
all have a sight glass to check the oil level and have a
drain plug to remove the old oil when changing. To
add oil remove vent cap from top of pump [See
Figure 19 (A)].

Figure 17 - Pump Oil Filler Vent Cap (A), Sight Glass
(B), and Drain Plug (C) Locations
