How to review and use the nozzles?

• Various nozzles may be quick-connected into the end of the wand to change the spray pattern. When using Quick Connects (Q.C.), be certain the connection is securely locked.
• If not, the high-pressure water may shoot the nozzle from the wand, causing severe injury or serious damage. To determine spray fan, refer to the actual number stamped on the nozzle. The first two digits indicate the spray fan in degrees, i.e.; 15=15°, 25=25°, 65=65°.
  • 15° nozzle (YELLOW): This is a chiseling nozzle. Direct the spray at a 45° angle to the surface and use it like a scraper to remove paint, grease, and dirt. Uses include surface preparation (removing mildew stains and paint chips).
  • 25° nozzle (GREEN): This is a flushing nozzle. This pattern is best suited for flushing dirt, mud, and grime. Uses include wet sweeping leaves from walks, curbs, and driveways, cleaning stable floors, washing swimming pool bottoms, and degreasing engines.
  • 65° nozzle (BLACK): This is a low-pressure detergent application nozzle. This broad spray pattern distributes solution over vast areas under low pressure. Uses include detergent application, misting, or rinsing.

---

How to connect the nozzle?

1. Be certain the trigger gun is locked in the “OFF” position.
2. The nozzle assembly should be disconnected from the gun assembly at this time by retracting the locking ring on the quick-connect fitting to remove the nozzle.

---

How to start the unit?

1. Refer to the “Safety Precautions” before starting the unit.
2. Locate the Safety Decals on your unit and heed their warnings.
3. With the gun locked in the “OFF” position, point the trigger gun away from yourself or anyone else. Ensure the water supply is completely turned on.
4. Disengage the safety lock-off on the gun and squeeze the trigger. Low-pressure water will begin flowing from the nozzle.
5. Be certain the trigger gun remains in an open position while starting the engine. Brace yourself as the gun will kick back from the high pressure created by the pump once the engine has started.
6. Steady the unit during engine start-up.
7. Once the engine has started, perform the following procedures with the gun open:
   • Inspect for system oil leaks and fuel leaks. If a fuel leak is found, TURN UNIT OFF IMMEDIATELY!
   • 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!
8. Trigger the gun several times and try adjusting the spray pattern. Be certain to LOCK the trigger gun in the “OFF” position whenever adjusting the spray pattern.
9. Do not allow the unit to operate in bypass mode (with trigger closed) for more than three minutes without triggering the gun.
10. Because your pressure washer delivers a high-pressure spray and a variety of spray patterns, there are many cleaning jobs that can be done without the use of detergents.

How to prime the pump?

1. It is essential to prime the pump on initial start-up and each time the water supply is disconnected from the unit after initial use.
2. Lay the high-pressure hose out to remove any loops. Water flow will constrict the hose, creating tight loops if the hose is not straight.
3. Securely connect the gun assembly to the high-pressure hose.
4. With the trigger gun locked in the “OFF” position, turn the water supply completely on. Pointing the gun in a safe direction, unlock the trigger gun and squeeze the trigger.
5. Low-pressure water will begin flowing from the hose/gun assembly. This allows the unit to prime and purge any air from the system. The unit is primed when water flow is uninterrupted by air.
6. Once the unit is primed, release the trigger and lock the gun in the “OFF” position. Securely connect the nozzle assembly.

---

How to clean with detergents?

1. Refer to “Detergent Cleaning Precautions”. Be certain to wear protective safety attire as stated.
2. Prepare detergent solution according to label directions. Never pump acids, alkalines, abrasive fluids, or solvents through the unit.
3. Connect the detergent hose to the unit. The detergent ratio is preset and cannot be adjusted.
4. Immerse the detergent strainer into the detergent solution to allow detergent to siphon.
5. With the trigger gun locked in the “OFF” position, move the nozzle cover at the end of the wand away from the trigger gun.
6. To apply solution, unlock the trigger gun and squeeze the trigger. In a few moments, a detergent/water mixture will exit the low-pressure nozzle.
7. Start spraying the lower portion of the surface being cleaned and move up, using long overlapping strokes.
8. To rinse, lock the trigger gun in the “OFF” position, and pull the nozzle cover at the end of the wand toward the trigger gun. Unlock the trigger gun and spray. It will take about 30 seconds to purge all detergent from the line.
9. Siphon a gallon of water through the low-pressure detergent injection system after each use.
