Dual Gun Option also requires the Trapping Unloader Option. This option splits flow between two discharges. Outlet Pressure at both guns will be the same as the unit’s rated pressure.
HIGH PRESSURE DETERGENT: (CLEANING WITH DETERGENTS)
NOTE: This feature is designed for use with mild detergents only. Since the cleaning solution travels through various parts of the pressure washer, 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”. 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 corrosive characteristics of many detergents commonly used in the pressure washer cleaning industry, it is recommended to use only mild detergents with this unit.)

  3. Fully immerse the strainer end of the clear vinyl detergent hose into the detergent solution.

  4. 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 apply cleaning solution to a small section at a time.

  5. To rinse; lock the trigger gun in the “OFF” position. Turn the detergent metering valve to the “OFF” position. 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.

  6. Siphon a gallon of water through the detergent injection system after each use. This prevents the possibility of corrosion or detergent residue causing mechanical problems during the next use.

STORAGE & MAINTENANCE

SPECIFIC MAINTENANCE:
EVAPORATIVE EMISSION COMPONENTS:
The unit you have purchased includes the following components that are in compliance with 2006 California Air Resources Board Evaporative Emission Standards;

  1. Fuel Hose
  2. Fuel Hose Fittings

These components should be inspected on a daily basis for cracks, leaks, and abnormal wear. If cracking, leaks or abnormal wear has occurred, the components should be replaced immediately.
ENGINE: The engine instruction manual accompanying your unit lists the specific procedures for maintenance on 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, the manufacturer recommends changing the oil every three months or at 250 hour intervals. If oil appears dirty or milky, changes may be required in greater frequency. Use SAE20 or 30 non-detergent pump oil and fill only to the center of the oil sight glass. DO NOT overfill.
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.
MAINTENANCE-EVERY 3 MONTHS:
CHANGE WATER PUMP OIL: Ensure unit is off. Change the pump oil after the first 50 hours of operation. After initial change, every 3 months or 500 hour intervals are recommended. If oil appears dirty or milky, changes may be required in greater frequency. Use SAE20 or 30 non-detergent pump oil and fill only to the center of the oil sight glass. DO NOT overfill.
REPLACE HIGH PRESSURE 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.
BELT INSPECTION: Ensure unit is off and remove the beltguards. Inspect the v-belt for wear and tightness. If the v-belt needs to be replaced or tightened, follow the procedures listed below:
Replacement:

  1. Loosen the four pump mounting bolts (A).
  2. Loosen the two alignment nuts approximately one inch on the alignment bolts (B1 & B2).
  3. Slide the pump toward the engine to loosen belts.
  4. Remove and replace belt.

Tighten: (If v-belt was not replaced, you will need to loosen the nuts on the alignment bolts B1 and B2 before proceeding.)

  1. Tighten B2 alignment bolt. The pump will shift to the left until there is tension on the belt. Then tighten B2 nut.
  2. Tighten B1 alignment bolt, until sheaves are straight. (Use a straightedge for alignment.)
  3. Push on the v-belt to check belt deflection for tension. There should be 1/4″ to 1/2″ deflection for correct tension.
  4. If sheaves are straight and tension is correct, tighten B1 nut and the four pump mounting bolts (A).
  5. If tension is not correct, repeat steps 6 and 7 until correct alignment and tension is achieved. Tighten the four mounting bolts (A) when completed.
  6. Loosen B2 nut, tighten B2 bolt, tighten B2 nut.
  7. Loosen B1 nut, tighten B1 bolt, tighten B1 nut.

MAINTENANCEBURNER 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). In colder temperatures or higher altitudes, it may be necessary to adjust the air supply to the combustion chamber.
This adjustment will maximize burner efficiency and avoid inefficient operation or excessive sooting of the heat exchanger coil.
A smoke spot test is recommended during any air shutter and band adjustment.
If you do not have the equipment to perform a smoke spot test, follow the procedures listed below.

  1. The machine must be running and the burner ON.
  2. Loosen the Locking Screw (#3 at left) on the shutter.
  3. Check for smoke from the heat exchanger exhaust. If smoke is not present, slowly close the Air Shutter (#1 at left) by moving the dial counterclockwise to a lower number. Continue moving the dial until smoke appears.
  4. Record this setting.
  5. Open Air Shutter (#1 at left) two increments. Example: If Air Shutter was set at 2, move it to 4.
  6. Slowly trigger the gun on and off. This will cause the burner to turn on and off. Look for a smoke puff when the burner ignites.
  7. Repeat steps 5 and 6 until a smoke puff is noticed. Record the Air Shutter Setting.
  8. The difference between the recorded settings in steps 4 and 7 is the combustion window. Set the dial 1/2 way between these settings.

NOTE: If you are unable to detect a setting on either step 3 or 7, more or less air may be needed to achieve a proper combustion window.
Loosen the Bolt (#4 at left) and open the Air Band (#2 at left) in 1/4″ increments. Repeat steps 3-8 until proper combustion window is achieved.
