GET TO KNOW THE PRESSURE WASHER

NOTE: Photographs and line drawings used in this manual are for reference only and do not represent a specific model. Save this manual for future reference.
NOTICE: The engine is shipped without oil. Before starting engine, add the oil provided. Damage to the engine will occur if the engine is run without oil, this damage will not be covered under warranty.

PRESSURE WASHER TERMINOLOGY
PSI: Pounds per Square Inch. The unit of measure for water pressure. Also used for air pressure, hydraulic pressure, etc. Operating at pressures exceeding the maximum rating could result in damage to the unit and/or severe personal injury.
GPM: Gallons per Minute. The unit of measure for the flow rate of water.
CU: Cleaning Units. GPM multiplied by PSI equals CU.
Pressure Wand Assembly: This refers to the gun, wand and nozzle.
Pump: The pump moves the water through the system and delivers it to the pressure wand assembly. The nozzle creates the pressure.
Bypass Mode: Allows water to re-circulate within the pump when the gun trigger is not pulled. This feature allows the operator to release the trigger gun and reposition themselves without having to turn the engine off in between cleaning actions.
NOTICE: Allowing the unit to run for more than two minutes without the gun trigger being pulled could cause overheating and damage to the pump. Do not let the pressure washer run for more than two minutes in Bypass Mode. Turn off the engine and relieve the pressure in the gun during these extended situations.
Thermal Relief Valve: When the temperature inside the pump rises too high, this valve will open and release a gush of water in an effort to lower the temperature inside the pump. The valve will then close.
Pressure Relief Valve: The water heater coils are designed to operate safely at normal working pressure. The safety pressure relief valve prevents over pressurization of the high pressure system. Do not modify the pressure relief valve in anyway.
High Pressure Pump Oil: The preferred oil is SIMPSON® Premium Pump Crankcase Oil. If this oil is not available, an SAE 15W-40 oil may be used. Change the pump oil after the first 50 hours of operation and every 100 hours thereafter, or every 3 months.
Gasoline Engine Oil (if equipped): Check engine oil level before each use. Refer to the Engine Owner’s Manual for correct procedure.
12V DC Battery (if equipped): The 12V DC battery operates the engine’s electrical start system, after the engine is started the system will charge the battery and operate the burner. The 12V battery will need to be replaced regularly to ensure consistent
performance. Recommended battery size: Colbalt, Streamliner use Group 24 battery /Patriot use U 1 battery.
Burner Assembly: A device used to change fuel to heat energy. It is used to heat the water in the coil assembly and is designed to use a NO. #2 diesel fuel.
BTU (British Thermal Unit): The amount of work or energy it takes to raise the temperature of one pound of water by one degree Fahrenheit.
Temperature Control: The burner system is equipped with an adjustable temperature control. Do not set thermostat above 195°F. The burner will shut off if insufficient water flow through the burner’s heater coil causes the outlet water temperature to be excessive.
Back Flow Preventer: Prevents backflow into a potable water system.
WARNING : To reduce the possibility of contamination always protect against backflow when connected to a potable water system
Pressure Switch: A switch which uses a pressure activated plunger to activate a microswitch, used to control the fuel solenoid in the burner system.
Flow Switch: A switch which responds to changes in water flow, water flow moves a magnet which ativates a reed or microswitch to control voltage to the fuel solenoid in the burner system.
Chemical Injection System: Mixes cleaners or cleaning solvents with the water to improve cleaning effectiveness.
High Pressure Hose: Only use a wire braid hose rated for the output pressure and temperature of the high pressure pump. Additional hose lengths can be added with quick twist couplers with a minimal loss in pressure of about .5 PSI per foot. Always inspect hoses for wear and replace if necessary. Avoid kinking or running over the hose to extend the hose life.
Hour meter (if equipped): The analog hour meter operates whenever the engine is running and keeps track of how many hours the unit has been used.
Water Supply: The minimum requirements for a water supply are 20 psi at twice the stated water volume for the machine. If your water source is a well, the garden hose length can only be 30 ft. (9 m) maximum.
EVAP canister (if equipped): Collects fuel vapors and later purges them so they burn in the combustion process.

TRANSPORT AND SETUP

Make certain the trailer frame is securely balanced before adjusting the position.
Do not use jack stand on an uneven surface and the tires should be blocked when lifting trailer off of ball mount.

1. Secure the tow vehicle and trailer from rolling (by blocking wheels) when operating the jack.
2. These jacks are designed for vertical loading. NOTE: Excessive side forces may cause jack failure and must be avoided.

The jack is not intended to be used as a transport device for the implement it is attached. Minimize movement of the implement while jack is under load.
NOTE: TOW trailer as level as possible. DO NOT operate on an incline.

Trailer Tongue Installation

1. Unfasten and unwrap tongue assembly from trailer crate base.
2. Slide tongue assembly into slot located under front section of trailer.
3. Slide lighting wiring through the tongue tube to the front end.
4. Check trailer lighting wire routing through tongue to make sure wires are not pinched, stretched, tangled or hung up.
5. The hardware is located on the front wire mesh tray. Mount tongue hardware through the tongue support angles and tongue tube. Tighten the hardware.
6. Swivel down the jack and crank jack further to take weight off of the front wooden shipping supports. With the weight off of the shipping posts, the wooden shipping support box can be removed.
7. Remove ratchet tie down strap from rear of the trailer.

Breakaway Hinge Trailer Tongue (if equipped)
The breakaway hinge trailer tongue has been welded for you at the factory.
The purpose of the hinge is to allow you to fold the tongue back when not in use, allowing the trailer length to be shortened for storage.
When you are ready to tow the trailer, swing the tongue forward then lock the hinge with the hinge pin. Once the trailer tongue is connected to the tow vehicle hitch ball, connect the safety chains to the tow vehicle via the quick connect links.

SAFETY CONCERN
Use of a hitch with a load rating less than the load rating of the trailer can result in loss of control and may lead to death or serious injury. Use of a tow vehicle with a towing capacity less than the load rating of the trailer can result in loss of control, and may lead to death or serious injury. Be sure your hitch and tow vehicle are rated for the Gross Vehicle Weight Rating (GVWR) of your trailer.

COMMON TOWING TERMS
Trailer Information — Certification/VIN Label – A trailer’s Certification/VIN Label is typically located on the tongue or front frame of the trailer.
MANUFACTURER – Name of trailer manufacturer
DATE OF MANUFACTURE – Month and year the trailer was manufactured.
GVWR – The Gross Vehicle Weight Rating is the maximum allowable gross weight of the trailer and its contents. The gross weight of the trailer includes the weight of the trailer and all of the items within it (such as cargo, water, food and other supplies).
GAWR – The Gross Axle Weight Rating is the maximum gross weight that an axle can support. It is the lowest of axle, wheel, or tire rating. Sometimes the tire or wheel rating is lower than the axle manufacturers rating, and will then deter- mine GAWR. The sum total of the GAWR for all trailer axles may be less than the GVWR for the trailer, because some of the trailer load is carried by the tow vehicle, rather than by the trailer axle(s). The total weight of the cargo and trailer must not exceed the GVWR, and the load on an axle must not exceed its GAWR.
TIRE SIZE – The tire size recommended for your trailer and load range.
PSIC – The “pounds per square inch- cold” is the tire pressure (Kilopascals / Pounds per Square Inch) measured when Cold.
CERTIFICATION STATEMENT – “This trailer meets all the Federal Motor Vehicle Safety Standards in effect on the date of manufacture shown above” .
VIN – The Vehicle Identification Number.
VEHICLE TYPE – Generally the word “trailer” is used. However, we may put a Model #, or additional descriptor. Definitions
TOW VEHICLE – When equipping a new vehicle or an older vehicle to tow your trailer, ask the vehicle dealer for advice on how to outfit the towing vehicle. Discuss the following information and equipment with the vehicle dealer.
OVERALL CARRYING AND TOWING CAPACITY OF VEHICLE – Vehicle manufacturers will provide you with the maxi- mum towing capacities of their various models, as well as the GCWR. No amount of reinforcement will give a 100 horse- power, 2,500 pound truck the towing capacity that a 300 horsepower, 5,000 pound truck has.
TOWING HITCH – The towing hitch attached to your tow vehicle must have a capacity equal to or greater than the load rating of the trailer you intend to tow. The hitch capacity must also be matched to the tow vehicle capacity.
SUSPENSION SYSTEM – A tow vehicle equipped with a factory installed “Towing Package” likely comes equipped with heavy duty springs, heavy duty tires and other suspension components which are able to serve the size and weight of the trailer that the vehicle is rated to tow. However, the addition of additional equipment may further improve the tow vehicle performance. These may include adjustable air shocks, helper springs, etc.
BRAKE CONTROLLER – The brake controller is part of the tow vehicle and is essential in the operation of the electric brakes on the trailer. If your trailer has electric brakes it requires a brake controller be installed at the driver’s position. The brake controller is not the same as the safety breakaway brake system that is installed on the trailer.
SIDE VIEW MIRRORS – The size of the trailer that is being towed and your state law regulations determine the size of the mirrors. However, some states prohibit extended mirrors on a tow vehicle, except while a trailer is actually being towed. In this situation, detachable extended mirrors are necessary. Check with your dealer or the appropriate state agency for mirror requirements.
HEAVY DUTY FLASHER – A Heavy Duty Flasher is an electrical component that may be required when your trailer turn signal lights are attached to the tow vehicle flasher circuit.
ELECTRICAL CONNECTOR – An Electrical Connector connects the light and brake systems on the trailer to the light and brake controls on the towing vehicle.
HEAVY DUTY ENGINE OIL COOLING SYSTEM – The tow vehicle engine works harder when a trailer is being towed. Depending on the size of the trailer, you may need to install a separate engine oil cooler. Inadequate cooling may result in sudden engine failure. Ask the tow vehicle dealer if it is necessary to install a heavy duty cooling system.
AUTOMATIC TRANSMISSION OIL COOLER – The automatic transmission of a towing vehicle handles more power when a trailer is being towed. Inadequate cooling will shorten transmission life, and may result in sudden transmission failure. Ask the tow vehicle dealer if it is necessary to install a separate oil cooler for the automatic transmission.
FIRE EXTINGUISHER – It is sensible to have a fire extinguisher in the tow vehicle.
EMERGENCY FLARES AND EMERGENCY TRIANGLE REFLECTORS – It is wise to carry these SAFETY CONCERN devices even if you are not towing a trailer. It is particularly important to have these when towing a trailer because the hazard flashers of your towing vehicle will not operate for as long a period of time when the battery is running both the trailer lights and tow vehicle lights.

COUPLING AND UNCOUPLING THE TRAILER
A secure coupling (or fastening) of the trailer to the tow vehicle is essential. A loss of coupling may result in death or serious injury. Therefore, you must understand and follow all of the instructions for coupling. The following parts are involved in making a secure coupling between the trailer and tow vehicle:
COUPLING – That part of the trailer connecting mechanism by which the connection is actually made to the trailer hitch.
This does not include any structural member, extension of the trailer frame, or brake controller.
HITCH – That part of the connecting mechanism including the ball support platform and ball and those components that extend and are attached to the towing vehicle, including bumpers intended to serve as hitches.)
WEIGHT DISTRIBUTING HITCH (OR EQUALIZING HITCH) – A mechanical device that connects the trailer to the towing vehicle and by means of leverage applied on both the trailer and towing vehicle structures, when properly adjusted, dis- tributes the imposed vertical load at the hitch and coupling connection between structures of the towing vehicle and trailer.
WEIGHT CARRYING HITCH – A mechanical and/or structural device that connects the trailer to the towing vehicle and that does not employ features designed to redistribute the load imposed at the hitch and carrying connection.
SAFETY CHAINS OR CABLES – Chains or cables permanently attached to the trailer such that if the coupler connection comes loose, the safety chains or cables can keep the trailer attached to the tow vehicle. With properly rigged safety chains or cables, it is possible to keep the tongue from digging into the road pavement, even if the coupler-to-hitch connection comes apart.
TRAILER LIGHTING AND BRAKING CONNECTOR – A device that connects electrical power from the tow vehicle to the trailer. Electricity is used to turn on brake lights, running lights, and tum signals as required. In addition, if your trailer has a separate braking system, the electrical connector will also supply power to the trailer brakes from the tow vehicle.
BREAKAWAY SWITCH (if equipped) – If the trailer becomes de-coupled from the towing vehicle, the breakaway switch lanyard, attached independently to the tow vehicle hitch, will pull a pin in the emergency electrical break-away switch on the trailer. The breakaway switch is activated by a separate battery supply in the trailer such as to energize the trailer brakes independently of the towing vehicle. It is important to check the state of charge of the emergency break-away battery before each trip. Simply pull the pin out of the switch by hand and then try to pull the trailer. If you feel a significant drag force the brakes are activated. Be sure to re-insert the pin in the break-away switch. Also be sure to allow enough slack in the break- away brake lanyard such that the switch will only activate (pin pulls out) if the coupler connection comes loose.
JACK – A device on the trailer that is used to raise and lower the trailer tongue. On larger trailers the jack is sometimes called the “landing gear.”

SAFETY CONCERN
An improperly coupled trailer can result in death or serious injury. Do not move the trailer until:

• The coupler is secured and locked to hitch
• The safety chains are secured to the tow vehicle
• The trailer jack(s) are fully retracted Do not tow the trailer on the road until:
• Tires and wheels are checked
• The trailer brakes are checked
• The breakaway switch is connected to the tow vehicle
• The load is secured to the trailer
• The trailer lights are connected and checked

Various Coupler Designs
Trailers are produced with a variety of coupler devices. Bumper pull (Ball Hitch) Coupler is the style used on all of the Trailer Mounted Wash System trailers.
Trailer with Ball Coupler
A ball coupler connects to a ball that is located on or under the rear bumper of tow vehicle. These systems of coupling a trailer to a tow vehicle are sometimes referred to as “bumper pull.”
A ball hitch trailer may be fitted with a tongue jack that can raise and lower the coupler. The tongue jack is mounted to the A-frame (front, or tongue) part of the trailer. By rotating the jack handle clockwise, the jack will extend and raise the tongue of the trailer. Be sure the ball hitch coupler is suitable for the size and weight of the trailer. The load rating of the coupler and the necessary ball size are listed on the trailer tongue. You must provide a hitch and ball for your tow vehicle, where the load rating of the hitch and ball are equal to or greater than that of your trailer. Also, the ball size must be the same as the coupler size. If the ball is too small, too large, is underrated, is loose or is worn, the trailer can come loose from the tow vehicle, and may cause death or serious injury.

THE TOW VEHICLE, HITCH AND BALL/PINTLE HOOK MUST HAVE A RATED TOWING CAPACITY EQUAL TO OR GREATER THAN THE TRAILER GROSS VEHICLE WEIGHT RATING (GVWR). IT iS ESSENTIAL THAT THE BALL BE OF THE SAME SIZE AS THE COUPLER.
The ball/pintle eye size and load rating (capacity) are marked on the ball/pintle eye; hitch capacity is marked on the hitch.
Before Coupling the Ball to the Tow Vehicle
Be sure the size and rating of the hitch ball match the size and rating of the coupler. Hitch balls, pintle hooks and couplers are marked with their size and rating.

SAFETY CONCERN
A worn, cracked or corroded hitch ball can fail while towing, and may result in death or serious injury. Before coupling trailer, inspect the hitch ball for wear, corrosion and cracks. Replace worn or damaged hitch ball.
Rock the ball to make sure it is tight to the hitch, and visually check that the hitch ball nut is solid against the lock washer and hitch frame.
Wipe the inside and outside of the coupler clean and inspect it visually for cracks and deformations; feel the inside of the coupler for worn spots and pits. If wear on the original surface profile exceeds 1/8” (.125” ), the coupler should be replaced.
Be sure the coupler is tight to the tongue of the trailer. All coupler fasteners must be visibly solid against the trailer frame.

SAFETY CONCERN
A loose hitch ball nut can result in uncoupling, leading to death or serious injury. Be sure the hitch ball is tight to the hitch before coupling the trailer.
Coupling to the Tow Vehicle – Raise the bottom surface of the coupler to be above the top of the hitch ball/pintle hook. Use the jack if one is provided; otherwise, use wood or concrete blocks to support the trailer tongue.

Coupling with a Ball Hitch
Lubricate the hitch ball and the inside of the coupler with a thin layer of automotive bearing grease. If your trailer is equipped with a jack, raise the coupler above the ball height. Open the coupler locking mechanism. Ball couplers have a locking mechanism with an internal moving piece (ball clamp) and an outside handle, wheel, or latch.
In the open position, the coupler is able to drop fully onto the hitch ball. Slowly back up the tow vehicle so that the hitch ball is near or aligned under the coupler, if the trailer jack has raised the coupler.
Ball Hitch Coupler Mechanism
If your trailer does not have a jack, you will have to lift the coupler and place it over the ball. If you have a jack, lower the trailer tongue until the coupler fully engages the hitch ball. If the coupler does not line up with the hitch ball, adjust the position of the tow vehicle. Engage the coupler locking mechanism. In the engaged position, the locking mechanism securely holds the coupler to the hitch ball. Insert a pin or lock through the hole in the locking mechanism. Be sure the coupler is all the way on the hitch ball and the locking mechanism is engaged.
A properly engaged locking mechanism will allow the coupler to raise the rear of the tow vehicle. Using the trailer jack, test to see that you can raise the rear of the tow vehicle by 1 inch, after the coupler is locked to the hitch.

SAFETY CONCERN
Overloading can damage the tongue jack. Do not use the tongue jack to raise the tow vehicle more than 1 inch. If the coupler cannot be secured to the hitch ball, do not tow the trailer.
Contact our Customer Service Department by calling 1-833-362-7368 or emailing cservice @fna-group.com Lower the trailer so that its entire tongue weight is held by the hitch, and continue retracting the jack to its fully retraced position.

RIG SAFETY CHAINS
Visually inspect the safety chains and hooks for wear or damage. Replace worn or damaged safety chains and hooks before towing. Rig the safety chains so that they: Criss-cross underneath the coupler so if the trailer uncouples, the safety chains can hold the tongue up above the road. Loop around a frame member of the tow vehicle or to holes provided in the hitch system (but, do not attach them to an interchangeable part of the hitch assembly) Attach snap hooks up from underneath the hole (do not just drop into hole); and provide enough slack to permit tight turns, but not be close to the road surface to drag.

SAFETY CONCERN
Improper rigging of the safety chains can result in loss of control of the trailer and tow vehicle, leading to death or serious injury, if the trailer uncouples from the tow vehicle.

• Fasten chains to safety chain receivers on the hitch, not to ball.
• Have sufficient slack to permit turning and to keep gooseneck on bed of tow vehicle, if the trailer comes loose.

ATTACH AND TEST BREAKAWAY BRAKE SYSTEM AND SAFETY COMPONENTS
If the coupler or hitch fails, a properly connected and working breakaway brake system will apply electric brakes on the trailer. The safety chains will keep the tow vehicle attached and as the brakes are applied at the trailer’s axles, the trailer/ tow vehicle combination will come to a controlled stop. The breakaway brake system includes a battery, a switch with a pull pin, and a lanyard.
The breakaway brake system may be fitted with a “charging” capability that draws power from the tow vehicle. If the electrical system on your tow vehicle does not provide power to the breakaway brake battery, you must periodically charge or replace the battery to keep the breakaway brake system in working order. Connect the pull pin lanyard to the tow vehicle so that the pull pin will be pulled out before all of the slack in the safety chains is taken up (see Breakaway Brake System figure). Do not connect the pull pin cable to a safety chain or to the hitch ball or hitch ball assembly.
This would keep the breakaway brake system from operating when it is needed.
To test the break-away brake battery, remove the pull pin from the switch and attempt to pull the trailer forward. You should feel the trailer resisting being towed, but the wheels will not necessarily be locked. If the brakes do not function, do not tow the trailer until brakes, or battery, are repaired. Immediately replace the pull pin. The breakaway brake system battery discharges rapidly when the pull pin is removed.

SAFETY CONCERN
An ineffective breakaway brake system can result in a runaway trailer, leading to death or serious injury if the coupler or ball hitch fails. Connect the breakaway cable to the tow vehicle; and NOT to the hitch, ball or support.
Before towing the trailer, test the function of the breakaway brake system. If the breakaway brake system is not working, do not tow the trailer. Have it serviced or repaired. Do not tow the trailer with the breakaway brake system ON because the brakes will  overheat which can result in permanent brake failure.

COUPLING TO THE TOW VEHICLE
Failure to replace the pull pin will prevent brakes from working, leading to loss of control, serious injury or death.
If you do not use your trailer for three or more months or during winter months store the battery indoors and charge the battery every three months. Replace if needed. Also, replace the breakaway brake battery according to the intervals specified by battery manufacturer.
Connect the trailer lights to the tow vehicle’s electrical system using the electrical connectors. Check all lights for proper operation. Clearance and Running Lights (Turn on tow vehicle headlights). Brake Lights (Step on tow vehicle brake pedal).
Turn Signals (Operate tow vehicle directional signal lever).
Check electric brakes for proper operation using brake controller mounted in the cab. If your trailer has electric brakes, your tow vehicle will have an electric brake controller that sends power to the trailer brakes. Before towing the trailer on the road, you must operate the brake controller while trying to pull the trailer in order to confirm that the electric brakes operate. While towing the trailer at less than 5 m.p.h., manually operate the electric brake controller in the tow vehicle cab. You should feel the operation of the trailer brakes.

GET TO KNOW THE PRESSURE WASHER OPERATING FEATURES

IMPORTANT: Become familiar with these features before operating this pressure washer.
PRESSURE ADJUSTMENTS
The pressure setting is preset at the factory to achieve optimum pressure and cleaning. If you need to lower the pressure, it can be accomplished by these methods.

1. Back away from the sur face to be cleaned. The further away you are, the less the pressure will be on the surface to be cleaned.
2. This pressure washer is equipped with an additional feature that allows the pressure setting to be adjusted.
   a. To lower the pressure, turn the unloader control knob (located under the hot water tank) counterclockwise to the desired pressure.
   b. To return the pump pressure to the factory setting, turn the unloader control knob (located under the hot water tank) clockwise until it stops.
