DANGER

The filled pressure washer is heavy. It can crush and cause serious injury if it rolls out of control or tips over.

• Always keep the jack cranked down to help balance the trailer when it is not connected to a vehicle hitch.

• Follow all the instructions below for safely connecting and towing the pressure washer.

CONNECTING TRAILER AND TOWING

Inspect Trailer

Always inspect the trailer before hitching it to your vehicle.

1) Check and be sure tires are fully inflated and in good repair. See tire sidewall for recommended pressure.

2) Check to make sure that trailer is in safe working condition. Make sure all nuts, bolts, and connections are

tight. If a part needs replacement, only use parts that meet the manufacturer's specifications.

3) Check coupler and latch be sure it is working properly.

4) Check to make sure coupler and ball size are the same.

5) Check wheel lug nuts to be certain they are tight.

6) Check all trailer lighting to insure they are in proper working order.

WARNING:

• Do not over-inflate tires. Severe injury can occur if tire explodes.

• Damaged or missing components, or replacement parts that do not meet specifications, may result in a

safety hazard or poor operation of the trailer.

Attach Trailer to Hitch

Attach trailer to vehicle hitch.

Trailer and tongue weights listed in the specification section of the manual. Ensure the towing vehicle is properly equipped to handle the load.

1) Attach trailer coupler to the vehicle’s class 4 or

higher hitch with 2-5/16" ball (only).

2) Ensure trailer is level, with A-frame tow bar parallel

to the ground. You may need to adjust your coupler height or purchase the proper hitch to achieve the correct tongue height, so trailer is level.

WARNING: Vehicle handling may be

adversely affected while towing if the trailer is not level.

3) Adjust coupler to ball by raising locking lever and turning lock nut with fingers. Proper adjustment is obtained

when coupler is as tight as possible on ball and locking lever can still be opened and closed.

4) Lock lever closed to secure the attachment.

An optional locking pin or padlock may be inserted in the locking lever hole for extra security.

Attach Safety Cables

Two safety cables must be used while towing.

Cross safety cables under the coupler, allowing only enough slack for vehicle turns.

Route Breakaway Switch

Cable

Route breakaway switch cable.

The breakaway switch is a device that will activate the trailer brakes should the trailer become disconnected from the tow vehicle. A cable is connected to a pin inserted into the breakaway switch. You must route this cable so that it will pull the pin out of the breakaway switch if the trailer begins to separate from the tow vehicle, which in turn will activate the trailer brakes.

• Select a Suitable Worksite

STEP 1. CHECK EQUIPMENT

Check/Add Pump Oil

Check/add pump oil.

CAUTION: Never run the pump without enough lubrication!

1) Check oil level. Verify that oil level is half way up the sight glass (or at the indicator line on the oil fill dipstick).

2) If oil level is low, fill using SAE Non-detergent 30wt. oil.

3) Replace oil fill dipstick.

Check/Add Engine Oil

Check the engine oil level and add oil as needed.

Use the recommended oil type for your engine and expected ambient conditions.

(See engine owner's manual for oil type and capacity, and more detailed oil check/fill instructions.)

WARNING: Burn hazard

Never open oil port while engine is running. Hot oil can spray over face and body.

NOTICE:

• Low oil shutdown feature prevents the engine from starting without enough oil.

• Engine is shipped with oil. You must check oil before first use.

Inspect Spray System

Always inspect spray system for damage and leaks before each use.

DO NOT START PRESSURE WASHER UNTIL ALL NEEDED REPAIRS HAVE BEEN COMPLETED.

WARNING: High pressure fluid injection hazard

High-pressure fluid discharge from leaks (even pin-sized) or ruptured components can pierce skin and inject fluid into the body. Injection injury can result in blood poisoning and/or severe tissue damage leading to infection, gangrene, and loss of limb.

• Never use a finger or skin to check for leaks.

• Never operate machine with damaged or missing hoses/parts.

• Never attempt to repair a high-pressure hose or component – Always replace it with a part that is rated at or

above the pressure rating of this machine.

1) Check hoses, fittings, wand, trigger gun, and connections for signs of wear, cracks, looseness, or leaks.

Replace as required.

2) Check and clean the nozzle orifice.

3) Clean inlet filter (see Maintenance & Repair).

Inspect Fuel System

Always inspect (engine and burner) fuel systems and check for leaks BEFORE starting pressure washer.

DO NOT START PRESSURE WASHER UNTIL ALL NEEDED REPAIRS HAVE BEEN COMPLETED.

WARNING: Fuel leak hazard

Gasoline fuel and burner fuels are highly explosive and fuel leaks can result in fire or explosions. You can be burned and seriously injured if the fuel system is not properly hooked up or there is a fuel leak when you start the engine.

Inspect the entire fuel system. Look for:

• signs of leaks or deterioration

• chafed or spongy fuel hose

• loose connections

Before Each Use

20 | P a g e

Any Questions, Comments, Problems, or Parts Orders

Call NorthStar ProSHOT Product Support 1-800-969-7073

• loose or missing fuel hose clamps

• damaged fuel tank, or a defective fuel shut-off valve

Clean Inlet Filter

Clean the water inlet filter before each use. For instructions see section Maintenance & Repair.

Perform Other Scheduled

Maintenances as Needed

Make sure that any other regular maintenance has been performed as prescribed in this manual in the Maintenance & Repair section.

1) Refer to the engine’s owner's manual for engine maintenance instructions.

2) Make sure battery is charged. Charge as needed according to your battery manufacturer's instructions.

STEP 2. ADD FUEL(S)

WARNING: Fuel fire/explosion hazard

Gasoline is highly flammable and explosive. Burner fuels are combustible at warm temperatures. Heat, sparks, and flames can ignite fu el vapors, which can become widespread during fueling. A flash fire and/or explosion could result and cause serious injury or death. Always use extreme care when handling fuels. Carefully follow all instructions to avoid the following conditions which could result in fuel ignition:

• gas vapor collection inside enclosures

• static electric sparks

• sparks from electric wiring, batteries, or running engines

• sources of heat (such as a hot engine, burner, or exhaust)

• open flames, including pilot lights

Always follow these general safety rules when fueling:

1) Turn pressure washer off and allow it to cool for at least two minutes before removing any fuel cap.

WARNING: A running, or still-hot engine or burner is hot enough to ignite fuel.

2) Fill fuel tank OUTDOORS – never indoors. Fuel vapors can ignite if they collect inside and enclosure and explosion can result.

3) Stay away from all sources of heat, sparks, and flames. Do not smoke.

4) Never pump fuel directly into the gas tank or burner at a gas station – it could cause a static electric spark.

Follow these steps to avoid static electric sparking during fueling:

• Use an approved portable container to transfer fuel to the pressure washer's tank. (A portable container made of metal or conductive plastic

is preferred because it dissipates charge to ground more readily.)

• Always place container on the ground to be filled. Never fill the portable gas container while it is sitting inside a vehicle, trailer, trunk, or pick-

up truck bed.

• Dissipate static charge from your body before beginning the fueling process by touching a grounded metal object at a safe distance from fuel

sources.

• Keep nozzle in contact with container while filling. Do not use a nozzle lock-open device.

Clean up fuel spills /splashes immediately.

• If possible, move the pressure washer away from spilled fuel on the ground.

• Wipe up spilled fuel and wait 5 minutes for excess fuel to evaporate before starting engine.

• Fuel soaked rags are flammable and should be disposed of properly.

If fuel is spilled on your skin or clothes, change clothes and wash skin immediately.

Fill Fuel Tank

Check the fuel tank level. If needed, fill tank with fresh fuel from a portable container:

1) Remove engine gas cap.

2) Add fuel through the fill opening:

Before Each Use

21 | P a g e

Any Questions, Comments, Problems, or Parts Orders

Call NorthStar ProSHOT Product Support 1-800-969-7073

- Use only a UL-approved portable fuel container to transfer the fuel to engine's tank.

- Do NOT overfill the fuel tank. Allow at least 1/2" of empty space below the fill neck to allow for fuel expansion.

3) Replace fuel cap securely before starting engine.

4) Store extra fuel in a cool, dry place in a UL-approved, tightly sealed container.

Fill Burner Fuel Tank (if

planning to use heated

water)

If you are planning to use heated water, fill burner fuel tank with #1 or #2 diesel, B5 or lower biodiesel, kerosene, or fuel oil.

1) Remove fuel cap.

2) Add fuel through the fill opening. Do not overfill. Allow at least 1/2" of empty space below fill neck to allow for

fuel expansion.

3) Replace fuel cap securely before starting engine.

4) Wipe any excess fuel from unit before starting.

Before using the pressure washer, you must understand the criteria for selecting a suitable location for operation. Note that this pressure washer is for OUTDOOR USE only.

WARNING: You must choose a suitable site for operating your pressure washer to avoid equipment damage and/or injury and death

from carbon monoxide poisoning, fire/explosion, uncontrolled equipment movement/tip over, or slips and falls. Choose a site that meets all the following five criteria:

1) OUTDOORS only, and away from all building windows and air intakes.

2) Where no flammable vapors, dusts, and gases are present.

3) Where there is adequate, unobstructed ventilation airflow.

4) With adequate clearance from combustible materials.

5) On a firm, level, heat-resistant surface with good drainage.

Details regarding each of these criteria are provided below.

Outdoor Use Only

DANGER: Carbon monoxide poisoning hazard

The location you choose to operate the pressure washer must be OUTDOORS and away from all building air intakes.

• Never run the pressure washer in an enclosed or partially enclosed location such as a building, garage, barn,

shed, or house. These spaces can trap poisonous gases. Running a fan or opening windows will not provide adequate ventilation to prevent dangerous CO build-up.

• Only use the pressure washer outdoors and far away from open windows, doors, and building or vehicle

vents.

• Place the pressure washer so that the exhaust fumes will not be directed towards people or building air

intakes.

• Ensure that working, battery-operated or battery back-up carbon monoxide alarms are used in any

dwelling/structure that is near the running pressure washer.

• Note that this pressure washer is NOT designed or approved for use in vehicles or marine applications.

Never run the pressure washer inside RVs or other vehicles, on boats, or on pick-up truck beds.

Stay Away from

Combustible Dust, Liquids

or Vapors

Do not locate and use the pressure washer in the presence of flammable vapors, dust, gases, or other potentially combustible materials.

The burner is an open flame, which can ignite airborne dusts and flammable vapors. Operate only where open flames and torches are permitted.

Be Sure to Have Adequate

Airflow

The pressure washer needs adequate, unobstructed flow of air to allow for proper combustion and adequate cooling.

Proper combustion can only be obtained when there is enough supply of oxygen available for fuel being burned. Cooling ventilation is required to prevent overheating of the pressure washer and fire.

• Situate so there is adequate clearance around pressure washer to allow for airflow – at least 7 feet from any

non-combustible wall or obstruction.

• Never place any objects against or on top of the pressure washer.

• Do not operate with a tarp, blanket, or cover surrounding the pressure washer.

Have Clearance for Hot

Exhaust

The exhaust gas from your pressure washer is extremely hot and can cause combustible materials to catch on fire.

• Make sure both the engine exhaust and burner exhaust are at least 7 feet from all combustible materials and

buildings/structures during operation.

• Equip the engine with a spark arrestor if the pressure washer will be used near any ignitable forest, brush, or

grassy land. (See the engine manual provided with this equipment to determine if the engine is already equipped.) Make sure you comply with applicable local, state, and federal codes.

• Keep a fire extinguisher rated "ABC" nearby. Keep it properly charged and be familiar with its use.

Have a Firm, Level Heat-

Resistant Surface

The pressure washer should be positioned on a firm, level (less that 3-degree slope), heat-resistant surface with good drainage.

Ensure that the pressure washer sites level and will not slide or shift during operation. If applicable, block the pressure washer’s wheel to prevent movement. Surface should be heat-resistant if you will be using the burner for heated spray.

• With adequate clearance from combustible materials.

• On a firm, level, heat-resistant surface with good drainage.

DANGER: Carbon monoxide poisoning hazard.

Exhaust fumes from both the engine and the burner contain carbon monoxide (CO), a poisonous gas you cannot see, smell, or taste. The CO generated by the pressure washer can rapidly accumulate, even in areas that appear to be well-ventilated, resulting in dangerous and fatal concentrations within minutes. ONLY run pressure washer OUTDOORS and at least 20 feet from the home, away from windows, vents, and air intakes, to allow proper ventilation. If you start to feel sick, dizzy, or weak while using the pressure washer, shut off the engine and get to fresh air RIGHT AWAY. NEVER run pressure washer inside any enclosed or semi-enclosed spaces, including homes, garages, basements, sheds, boxes, pick-up truck beds, RVs, or boats. These spaces can trap poisonous gases, EVEN if you run a fan or open windows.

Fill Water Tank

Ensure the water in your tank is clean. Debris can cause excess pump wear and reduce performance.

1) Use low pressure hose with garden hose to fill tank.

2) Fill from the drain tank.

3) Fill from top of tank.

Attach Gun to the

High-Pressure Hose

Attach the high-pressure hose to the pressure washer's water outlet.

WARNING: NEVER operate this pump with components (such as hose, connections, and spray gun) rated for

lower pressure and/or temperature limits than the machine's maximum rated pressure and temperature, or component could rupture and cause serious personal injury from escaping high pressure fluids.

1) See Component Identification section of this manual for location of the pressure washer's water outlet.

2) Your pressure washer hose is equipped with quick couplers. Simply pull the collar back and push the coupler onto

Figure 2b

Select the Spray

Nozzle

Your pressure washer is equipped with 15 high-pressure nozzles and 3 low-pressure nozzles (1 #7.0 Steam and 2 #3.0 Steam nozzles). Generally, the wider the spray angle of the nozzle, the lower the spray pressure produced. Select

nozzles based on the type of job you are doing (color of nozzle) and whether you are using two guns or one (size of nozzle).

1. One gun vs. two-gun use:

a) Use a #9.0 nozzle for single gun operation. This will ensure the rated flow and psi are achieved. b) Use two #4.5 nozzles when operating dual guns. c) Use a #7.0 yellow steam nozzle for single gun operation. d) Use two #3.0 yellow steam nozzles when operating dual guns.

WARNING: NEVER use #9.0 nozzles when operating both guns. If two operators use #9.0 nozzles and one

operator releases the trigger on their gun, the flow through the second operator’s gun will suddenly increase from 4.5 to 8 GPM. This will cause the second operator’s gun to kick without warning, which could result in loss of balance and/or

spraying control.

2. Type of cleaning job:

Select the appropriate color nozzle for the job based on the following table. Generally, the wider the spray angle of the nozzle, the lower the spray pressure produced.

Attach nozzle to the spray gun.

WARNING: DEPRESSURIZE FIRST

Any time you remove/install/change a nozzle, you must depressurize hose line by squeezing the spray gun trigger while the engine is off. Even if the engine has been off for a long period of time, the hose may remain dangerously pressurized.

1) Make sure the engine is off and the hose line

depressurized.

2) To install the nozzle, pull the collar back and twist the

nozzle firmly into the coupler on the end of the wand (Figure 3a).

Figure 3a

3) Release the collar, making sure it springs back and re-seats to its original (non-retracted) position (Figure 3b).

Check the connection by pulling on the nozzle to ensure a tight connection -- if correctly inserted, nozzle will rotate but not pull out.

WARNING: Make sure the nozzle is correctly inserted. Sprayer nozzle can become a projectile and cause serious

personal injury or property damage if not properly connected to the spray gun. Do not attempt to use different types of nozzles that may not fit the coupler.

Figure 3b

STEP 2. SET UP FOR CHEMICAL SPRAY (IF DESIRED)

Using the proper cleaning chemical for the application can speed up cleaning jobs tremendously.

Your pressure washer is equipped with a chemical tank and chemical injector, which siphons cleaning chemicals into a low-pressure washer spray downstream of the pump. Adequate suction pressure is created only when the low pressure (black) spray nozzle is used. The introduction of cleaning chemicals via the chemical injector affords the following advantages:

• It protects the pump from damage because no chemical passes through the pump.

CAUTION: Certain chemicals, such as bleach or those containing muriatic acid, will cause pump damage if introduced upstream through the

pump's water inlet.

• It mixes the cleaning chemical into a low-pressure spray. Cleaning chemicals applied under low pressure adhere better to the surface

being cleaned, allowing the formula time to react and remove dirt more effectively.

NOTICE: An external chemical injector pump is not recommended for use with this pressure washer.

WARNING: Chemical Spraying

• Never spray acids, corrosives, or abrasive or flammable liquids. Breathing hazards, surface burns/corrosion, or fire/explosion

could result.

Follow the chemical manufacturer's label instructions for proper use and handling of the chemical. Understand all safety hazards and first aid for all chemicals being used. Always wear protective gloves when handling and cleaning with chemicals, and wear other protective gear as directed by chemical manufacturer. Always dispose of hazardous fluids per local, state, and national guidelines.

DANGER: Do not inhale engine exhaust. It contains dangerous carbon monoxide that can kill you.

Apply Cleaning

Chemical (if desired)

If desired, spray cleaning chemical at low pressure (with or without heated water).

1) Make sure the chemical injector is properly set up according to the instructions in Step 2, Set Up for Chemical

Spraying.

2) Make sure the low-pressure BLACK nozzle is attached before beginning to spray chemicals -- Only the low-pressure

black nozzle will allow chemicals to be drawn through the chemical injector into the water stream.

3) You can apply chemicals with either warm or cold water. Check chemical label. If warm water is specified, start

burner according to instructions provided below.

4) Apply chemicals by squeezing the spray gun trigger. The chemical injector will draw the chemical into the water

stream.

5) Apply chemicals evenly to the cleaning surface. Never use more chemical than is necessary to clean the surface.

6) Allow the chemicals time to react with the dirt before rinsing.

7) Prepare to rinse by changing to a high-pressure nozzle. Changing the nozzle from the low-pressure black nozzle to

a high-pressure nozzle will stop the flow of chemicals into the water stream.

Refer to instructions for selecting and changing the nozzle in Step 1, Connect Hoses, Water Supply, and Nozzle.

8) Rinse with high-pressure spray, either hot or cold, as instructed below.

Turn on Burner (if hot

spray or steam is

desired)

Spray

High Pressure Spray Procedure

WARNING: High pressure spraying safety

• Keep spray away from people. Never direct discharge stream at or near any person. Do not allow any part of the

body to meet the fluid stream. High-pressure spray can cause serious skin, eye, or falling injuries, and hot water can burn. Injection injury will occur if high-pressure spray pierces the skin, injecting liquid under the skin. Injection injury can result in blood poisoning and/or severe tissue damage leading to infection, gangrene, and amputation. Seek medical attention.

• Do not secure trigger open. To reduce risk of injury, do not attempt to

secure the spray gun open by blocking or tying the spray gun in the open position.

• Prevent slips / loss of balance. High-pressure spray could cause you

to lose balance from kickback forces, and wet surfaces can be slippery.

- Always keep good footing and balance. Do not overreach.

- Do not stand on unstable support when spraying.

- If spraying from an elevated surface, use fall protection because spray gun kickback can propel you off the

elevated surface. When spraying from a ladder or scaffolding, ensure it is firmly anchored from sway or tip-over.

• Be aware of puddles and slippery surfaces. Ensure there is adequate drainage to prevent pooling of water.

• Prevent surface damage & flying debris. Surfaces being sprayed must be strong enough to withstand high-

pressure spray or damage may result. In addition, high-pressure spray will dislodge unsecured objects as well as surface chips and debris, resulting in hazardous flying objects that can cause personal injury or property damage. Do not spray brittle surfaces or breakable, fragile, or unsecured objects such as:

• stucco or laminar flagstone

• some painted surfaces

• windows or glass doors (because they may break)

• light fixtures, flowerbeds, mailboxes

• unsecured, lightweight objects

Procedure:

1) Put on one of the high-pressure spray nozzles (always relieve system pressure first and follow instructions for

attaching a nozzle).

2) Clear the cleaning area of all persons. Keep children and pets away.

3) Hold the spray gun firmly with two hands and a sturdy stance: (gun kicks back when triggered).

CAUTION: Spray gun metal gets extremely hot when using the burner and can burn you on contact. Never touch the

metal screw or any metal parts of the spray gun when the heater is being used. Use only designated grip areas.

4) Wash from the bottom to the top, using side-to-side motions. This washes away heavy dirt and allows the detergent

to soak as you work toward the top.

5) Use the width of the spray pattern to wash a wide path. Overlap the spray path for complete coverage.

6) The nozzle should be 12" to 24" from the work, closer for tough areas.

7) Small parts should be washed in a basket, so the pressure does not push them away. Larger, lightweight parts

should be clamped down.
