WARNING RISK OF INJECTION CAUSING SEVERE INJURY! -THE TRIGGER GUN SHOULD ALWAYS BE LOCKED IN THE OFF POSITION WHEN NOT IN USE! -NEVER LOOK DIRECTLY AT THE NOZZLE UNLESS IT IS DISCONNECTED FROM THE TRIGGER GUN/DUAL LANCE ASSEMBLY!

This unit features a Dual Lance Assembly with adjustable pressure which allows the user to select a high or low pressure “fan” spray. Simply rotate the adjustable grip on the dual lance to achieve the desired pressure selection.

1. Selection of high pressure can be achieved by turning the adjustable grip on the Dual Lance assembly counterclockwise as shown in the figure below.
   
   WATER INLET STRAINER
2. Selection of low pressure detergent application can be achieved by turning the adjustable grip on the Dual Lance clockwise as shown in the figure below. Once the pressure is low enough, the detergent injector on the pressure washer will draw detergent into the system. A water/ detergent mixture exits from both the spray nozzle and detergent nozzle.

DUAL LANCE CONNECTION:

1. Be certain the trigger gun is locked in the “OFF” position.
2. Connect the dual lance assembly to the trigger gun assembly at this time.
   Be certain the connection is securely tightened.
   

WATER SUPPLY:

1. Select a water supply hose which is a quality grade of garden hose measuring at least 3/4″ ID and no longer than 50 feet.
2. Check the see-through water filter to ensure it is clean and free of any obstructions. Periodic cleaning of the see-through water filter will help prevent pump problems. As a filter screen becomes obstructed, it restricts proper flow of water to the pump. This can result in cavitation which will cause premature failure of pump packing.
   a. Unscrew the garden hose inlet connection from the front of the filter assembly.
   b. Remove the clear plastic cover and clean the filter screen.
3. Connect the hoses:
   a. Connect one end of the water supply hose to the water inlet of the unit.
   b. Connect the other end of the hose to your pressurised water supply.
   When connecting the water inlet to the water supply mains, local regulations of your water company must be observed. In some areas, the unit must not be connected directly to the public drinking water supply. This is to ensure that there is no feedback of the detergents into the water supply. (Direct connection is permitted if a back flow presenter is installed.)
   c. Quick-connect the high pressure discharge hose to the water outlet of the unit.
   d. Connect the other end of the discharge hose to the gun.
4. Follow the incoming water requirements listed below:
   a. Water pressure must be a minimum of 25 pounds per square inch (PSI) and a maximum of 125 PSI. (A typical outdoor faucet will generally supply this PSI if turned completely “ON”.)
   b. Incoming GPM must be approximately one gallon more than the outgoing GPM stated on the pressure washer nameplate. (You can check GPM by timing how long it takes to fill a 5 gallon container.)
   c. Incoming water temperature must not exceed 125°F. Excessive pump damage may result if the water temperature exceeds this acceptable level.
5. Never allow the unit to operate without the incoming water line attached and the water supply completely turned on.

UNLOADED:
CAUTION RISK OF UNIT DAMAGE! DO NOT OVER TIGHTEN THE UNLOADED. BREAKAGE COULD RESULT IN IMMEDIATE LOSS OF WATER PRESSURE AND COSTLY REPAIRS.

The pressure has been preset at the factory and should only be adjusted by a trained Service Representative.

THERMAL RELIEVE VALVE:

To ensure the water temperature does not exceed acceptable levels, never allow the pressure washer to operate in the bypass mode (with the unit running and the trigger closed) for more than three minutes.

A thermal relieve valve has been added to this unit to protect the pump. It may begin to open and release water if the water temperature in the pump has exceeded 140° F. This will allow fresh, cool water to enter the system, therefore preventing premature failure of pump packing.

PRE-START INSPECTION PROCEDURES:

Before starting the unit, perform the following procedures:

1. Check the oil level in the pump and engine.
2. Inspect the water inlet strainer. Clean or replace if necessary. See “Water Supply”, #2.
3. Check all hose connections to ensure they are securely tightened. See “Water Supply”, #3.
4. Inspect for system water leaks, oil leaks and fuel leaks. If a fuel leak is found, DO NOT START UNIT! See “Risk of Explosion or Fire”. Be sure that all damaged parts are replaced and that the mechanical problems are corrected prior to operation of the unit. If you require service, contact Customer Service.
5. Inspect high pressure hoses for kinking, cuts and leaks. If a cut or leak is found, DO NOT USE HOSE! Replace hose before starting unit. See “Risk of Injection”. Be sure that all damaged parts are replaced and that the mechanical problems are corrected prior to operation of the unit. If you require service, contact Customer Service.

DO NOT ALTER OR MODIFY THIS EQUIPMENT IN ANY MANNER!

OPERATING INSTRUCTIONS

PRIMING THE PUMP:
CAUTION RISK OF UNIT DAMAGE. BE CERTAIN THE HOSE, GUN & DUAL LANCE ASSY. ARE NOT CONNECTED TO THE UNIT WHILE PRIMING THE PUMP. PRIMING ALLOWS MINERAL DEPOSITS TO BE RELEASED FROM THE SYSTEM WHICH WOULD OBSTRUCT OR DAMAGE THE GUN AND NOZZLE ASSEMBLY RESULTING IN COSTLY REPAIRS.

It is essential to prime the pump and flush the unit each time the water supply has been disconnected from the unit OR whenever the unit has set for any period of time. This unit has a steel coil which, after setting, will cause the water remaining in the coil from the previous usage to turn brown or black. This contaminated water must be flushed from the system before start-up. This procedure should be performed without the high pressure hose, gun and dual lance assembly installed.

DIRECT FEED: ALL UNITS.

1. Turn on the water supply.
2. Low pressure water will begin flowing from the water outlet. This allows the unit to prime and purge any air from the system. The unit is primed when water flow is uninterrupted by air.
3. Once the unit is primed, turn off the water supply and connect the high pressure discharge hose to the water outlet of the unit. (Note: The trigger gun and dual lance assembly should already be connected to the high pressure discharge hose at this time.)
4. Turn on the water supply.

START-UP/COLD WATER OPERATION:

1. Refer to the “Safety Precautions” before starting the unit.
2. Locate the Safety Decals on your unit and heed their warnings.
3. Ensure the burner switch is in the “OFF” position.
   DANGER RISK OF INJECTION CAUSING SEVERE INJURY! -KEEP CLEAR OF NOZZLE! NEVER PLACE HAND OR FINGERS IN FRONT OF NOZZLE! -DO NOT DIRECT DISCHARGE STREAM AT PEOPLE OR PETS!
4. Pointing the trigger gun in a safe direction, unlock the trigger gun and squeeze the trigger. Hold the trigger gun open while starting the engine according to the manufacture’s instructions in the engine manual accompanying this unit.
5. Once the engine has started, ensure the engine throttle is adjusted to full RPM and perform the following procedures with the trigger gun open:
   a. Inspect for system water leaks, oil leaks and fuel leaks. If a fuel leak is found, TURN UNIT OFF IMMEDIATELY! See “Risk of Fire”. Be sure that all damaged parts are replaced and that the mechanical problems are corrected prior to operation of the unit. If you require service, contact Customer Service.
   b. Inspect high pressure hoses for kinking, cuts and leaks. If a cut or leak is found, DO NOT TOUCH HOSE AT LEAK!!! TURN UNIT OFF IMMEDIATELY! Replace hose before starting the unit. See “Risk of Injection”. Be sure that all damaged parts are replaced and that the mechanical problems are corrected prior to operation of the unit. If you require service, contact Customer Service.
6. At this point, the unit is operating as a cold water pressure washer. Trigger the gun several times and try adjusting the water pressure. NEVER place hand or fingers in front of the nozzle or look directly into the nozzle! High pressure water creates a risk of severe injury
7. Do not allow unit to operate in bypass mode (with trigger closed) for more than three minutes without triggering the gun. Failure to follow this simple rule can cause premature failure of pump packing, resulting in costly pump repair.
8. Your pressure washer can deliver high pressure spray and a variety of spray patterns using cold water. If you wish to use the Hot Water application or Cleaning with Detergents, see page 17 for the correct procedures.

CAUTION RISK OF DAMAGE. DO NOT ALLOW SPRAY PATTERN TO REMAIN ON A FIXED AREA FOR AN EXTENDED PERIOD OF TIME. POSSIBLE DAMAGE MAY OCCUR TO THE AREA.

HOT WATER OPERATION:

WARNING RISK OF BURN! THE WATER TEMPERATURE COULD BECOME VERY HOT DURING HOT WATER OPERATION. BE CAUTIOUS WHEN ADJUSTING PRESSURE OR CONTROLLING THE TRIGGER GUN/DUAL LANCE ASSEMBLY.

1. Follow the steps outlined for “START-UP/COLD WATER OPERATION”.
2. Move the Burner Switch to the ON position. On initial start-up, water will begin turning hot in approximately 20 seconds and will reach maximum temperature in approximately 2-1/2 minutes, provided the trigger remains squeezed. The burner will stop firing when the trigger is released.

NOTE: While spraying, it is normal for the burner to fire intermittently.
The high-limit switch will cause combustion to cease when the temperature of the discharged water exceeds the maximum temperature setting of the switch. Combustion will begin again when the temperature drops below the minimum setting.

At this point, the unit is operating as a hot water pressure washer. Be certain to be extremely cautious when adjusting the pressure and controlling the trigger gun/dual lance assembly to avoid the possibility of burns.

CLEANING WITH DETERGENTS UNDER LOW PRESSURE:

NOTE: This feature is designed for use with mild detergents only. Since the cleaning solution travels through the heat exchange coil, DO NOT use corrosives as they will cause extensive damage as well as pose a considerable safety hazard.

1. Refer to “Risk of Bodily Injury/Detergents” pg. 7. Be certain to wear protective safety attire as stated on pg. 12.
2. Prepare detergent solution according to label directions. (Never pump acids, alkalines, abrasive fluids or solvents through the unit. Due to the unknown and often corrosives characteristics of many detergents commonly used in the pressure washer cleaning industry, it is recommended to use only manufacturer approved detergents with this unit.)
3. Fully immerse the strainer end of the clear vinyl detergent hose into the detergent solution.
4. Adjust the amount of detergent desired by locating the adjustment knob at the end of the clear vinyl hose. Turn the knob completely counterclockwise  to set at maximum siphon rate. Be certain the adjustable grip on the dual lance is turned completely clockwise for low pressure detergent operation.
   NOTE: This injection system is designed to apply detergents under low pressure only. It will not allow detergent solutions to be introduced into the system unless the dual lance is set in the low pressure mode.
5. To apply solution; unlock the trigger gun and squeeze the trigger. In a few moments a detergent/water mixture will exit the nozzle. Start spraying the lower portion of the surface being cleaned and move up, using long overlapping strokes. Applying from the bottom up helps avoid streaking.
   Allow to soak briefly. Avoid working on hot surfaces or in direct sunlight to minimize the chances of the detergent drying, which may result in damaging surfaces. Be certain to clean a small section at a time.
6. To rinse; lock the trigger gun in the “OFF” position, rotate the adjustable grip on the dual lance counterclockwise for high pressure. Unlock the trigger gun and spray. It will take about 30 seconds to purge all detergent from the line. For best rinsing results, start at the top and work down.
7. Siphon a gallon of water through the low pressure detergent injection system after each use. This prevents the possibility of corrosion or detergent residue causing mechanical problems during the next use.

SHUT-DOWN:

1. Move the burner switch to the OFF position.
2. Squeeze the trigger and discharge the water for a period of three minutes to cool the heat exchange and high pressure hose. (Insufficient cool down period of the high pressure hose will cause excessive wear and eventual rupturing of the hose.)
3. DO NOT close the choke to stop the engine. Backfire or engine damage may occur.
4. Move the engine On/Off Switch to the “off” position.
5. Close the engine fuel shut-off valve.
6. Turn off the water supply and trigger the gun momentarily to relieve trapped pressure.
7. Disconnect and store hoses. Store unit in a non-freezing environment.

STORAGE & MAINTENANCE

SPECIFIC MAINTENANCE:

ENGINE: The engine instruction manual accompanying your unit, lists specific procedures for maintenance of the engine. Following the engine manufacturer’s recommendations will extend engine life.

PUMP: Change the pump oil after the first 50 hours of operation. After initial change, every 3 months or 250 hour intervals are recommended. If oil appears dirty or milky, changes may be required in greater frequency. Use 15W20 detergent pump oil and fill only to the center of the oil sight glass. DO NOT overfill.

COUPLERS: There are o-ring seals inside the couplets which will deteriorate. To replace, simply install a replacement o-ring to correct the leak. (Additional o-rings can be purchased from your dealer.)

NOZZLE: Water flow through the spray nozzle will erode the orifice, making it larger, resulting in a pressure loss. Nozzles should be replaced whenever pressure is less than 85% of the maximum. The frequency of replacement will depend upon such variables as mineral content in the water and number of hours the nozzle is used.

FUEL WATER SEPARATOR: The fuel filter has a built in water separator. Occasionally the water has to be drained from the separator. Follow the procedures listed below:

1. Check the collection bowl daily.
2. Ensure the unit is off and place an oil catch basin under the fuel cartridge.
3. Loosen the drain plug to allow the fuel/water contaminants to flow into the catch basin.
4. Re tighten the drain plug when completed.
5. Dispose of drainage according to environmental regulations in your area.

BURNER AIR ADJUSTMENT: The air shutter has been factory preset for proper operation between sea level and 2000 feet elevation at standard conditions (60°F ambient water and air temperatures). To assure maximum combustion efficiency at colder temperatures and higher altitudes, it will be necessary to adjust the air supply to the combustion chamber. A smoke spot test is recommended during any air shutter adjustment. This will aid in maximising the burner efficiency and avoid inefficient operation and excessive suiting of the combustion chamber.

1. The machine must be running and the burner ON.
2. Take a smoke spot test to determine if more or less air is required for proper combustion.
   a. If the test is greater than a #3 smoke, turn the shutter arm counterclockwise to increase the air flow into the combustion chamber.
   b. If the test is yellowish in color, turn the shutter arm clockwise to decrease the air flow into the combustion chamber.
3. Hold onto the air shutter adjusting arm and loosen the locking nut. Move the shutter in 1/8″ increments and retighten the locking nut after each 1/8″ movement.
4. Trigger the gun on and off slowly to make sure there is proper ignition. Slight or no puffing on the ignition, and a smoke spot test of less than #3 smoke is good.
5. Repeat steps 2 and 3 until step 4 is attained.

LEAKS: Promptly eliminate any leaks found in the pumping system by removing suspect parts, applying thread sealant to the threads and reinstalling.
NOTE: If using Teflon tape, be certain no tape gets inside any plumbing to prevent the possibility of a plugged spray nozzle.
