Use of Detergent

- The Pressure Washer is built to use detergents specified for "descending flow" gas pressure washers.

CAUTION • Use only detergents designed for gas pressure washers. Household detergents, acid, alkaline, bleach, solvent flammable or industrial grade solutions can damage the pump. Many detergents call for mixing before using. Prepare the mix following the instructions in the bottle. Always test in a less noticeable area before starting to pressure wash. • Connect the detergent hose as indicated in page 7. • Remove the detergent container cap and insert the detergent hose end with the container filter.

NOTE The gas pressure washer uses a 20:1 proportion of detergent. It usually is a 1 gallon undiluted detergent. See the instruction in your detergent to verify if is necessary to make an additional dilution.
- Set the detergent nozzle (black) in the spraying pipe.
- Press the trigger and wait approximately 5 seconds for the detergent to start being sprayed.
- Spray the detergent in a dry surface using long, uniform and overlapped passes. To prevent stripes to appear, do not leave the detergent drying in the surface.
- After spraying detergent in the work surface and before rinsing, set the end of the detergent hose with the filter into a bucket with clean water and expel the water with the high-pressure gun during two minutes to remove from the system all the detergent residues.
- Turn off the motor and press the trigger to pressure-purge the water.

Rinsing

  • Remove the detergent nozzle and replace it with the high-pressure nozzle most suitable for the job.
    CAUTION Follow the nozzle assembly and removal instructions and how to select the most adequate nozzle in page 9.
  • Remove the detergent hose from the gas pressure washer.
  • Start rinsing from the upper side of the work area. Use side-to-side passes, overlapping each pass up and down.

Moving the Gas Pressure Washer

CAUTION • Never use the handle to lift the gas pressure washer. Never set the unit in a position other than vertical and sitting on its wheels. • Turn off the gas pressure washer. • Tilt the unit towards you until is balanced on its wheels. Then, push it to the desired position. Do not tilt forward or sideways while moving it.

CAUTION • DO NOT try to move the unit pulling from either of the hoses.

High Altitude Operation

  • At high altitude the air fuel mix in the standard carburetor will be rich in fuel. Performance will be lower and fuel consumption will increase.
  • Performance while in a high altitude can be increased if the carburetor is regulated adjusting the main knob. The equipment is set to operate at heights above 6000 feet above sea level. If the tool is not working efficiently call a
    TRUPER® Authorized Service Center to have them carry out modification in the carburetor.
  • Even though the carburetor has an adequate injection the potency in the motor will decrease 3,5% approximately per each 1000 feet increment, after 6890 feet above sea level. Decrease in potency will be higher if there are no modifications in the carburetor.

WARNING • If the equipment is operated in a height that is inadequate to the carburetor setting, low performance, over-heating and severe damage to the motor caused by the excessive air mix in the fuel may be obtained

CAUTION • Use only TRUPER

original spare parts.

CAUTION • When servicing or repairing the Pressure Washer use eye protection complying with ANSI Z87.1.

CAUTION • Before servicing the Pressure Washer, shut off water supply, shut off the motor, press the trigger to release pressure, disconnect all the hoses, disconnect the spark plug cable and set it apart.

- Failure to comply with any of the previous points exposes the operator to severe injury or damage the Pressure Washer thus making the warranty void.

General Maintenance

  • Use a clean cloth to remove dirt, dust, oil or grease from the unit. ⚠ CAUTION Refrain from using detergent when cleaning the plastic parts. Use care not to make contact of the plastic parts with fluid like brake fluid, gasoline, other petroleum-based products, penetrating oils, etc. Otherwise the plastic could damage, it would alter the unit operation and expose the operator to severe injury.
    • Periodically double-check the bolts, nuts and screws to be firmly tightened.
    • Periodically check the filter to make sure is clean.
  • Verify oil and fuel levels to fill up when necessary.
  • Check the jack-line. If frayed, replace it immediately in a

TRUPER Authorized Service Center.

Nozzle Cleansing

  • Nozzles can get partially obstructed due to residues, thus increasing pressure in the high-pressure gun. This issue can be detected if there is constant pulsating when pressing the trigger.
    • To solve this issue turn off the Pressure Washer and remove the nozzle as indicated in page 9.
  • Using a paper clip, remove the obstruction from the nozzle.
  • Set the nozzle in the front end of the garden hose. Open the faucet so that the water flow goes through the nozzle in an inverse sense and releases the rest of dirt.
  • Connect back the nozzle into the metal spear.

Air Filter Cleansing

  • Check the air filter once a month to make sure it is in good repair. Remember, a dirty filter can cause trouble when the motor is started, loss of performance and shorten the useful life of the motor.
  • Uncover the air filter cover loosening and removing the wing nut.
  • Using a damp cloth clean inside and out the filter cover. Do not allow dust to enter into the carburetor.

  • Remove the sponge air filter and rinse it with clean water.

  • Remove the sponge air filter and rinse it with clean water.
  • Press the filter lightly to remove the excessive water.
  • Apply a thin layer of motor oil to the filter. Let it drip.
  • Set the filter in place. Double-check it sits perfectly into the compartment. Otherwise, dust will enter the motor and cause premature wear.
  • Set the filter cover back in place. Tighten the wing nut.

Oil Change

  • Set an approved oil container under the unit.
  • Uncover the oil tank inlets and remove the hex screw in the lower side of the motor. Drain the oil into the container.
  • Before filling up again, set and tighten the hex screw and follow instructions in page 8.

Spark Plug Maintenance

  • Before removing the spark plug clean the area around the spark plug base to stop dust or debris enter into the motor. Remove the spark plug.
  • Clean the carbon deposits from the spark plug electrodes. Use a spark plug cleaner or a wire brush.
  • If you find the old one is worn or using it again is doubtful replace the spark plug using an identical LG F7RTC spare plug.
  • Verify the gap between electrodes. It shall be 0,027" to 0,031". If necessary, adjust the gap by carefully bending the earth connection electrode.
  • Verify the spark plug joint.
  • Set the spark plug in place. Thread it and tighten by hand.
  • Tighten with a wrench to compress the washer. If it is a new spark plug, give it a 1/2 turn to press the washer in an adequate manner. If using an old spark plug give it an 1/8 to 1/4 turn to compress the washer properly.

CAUTION Use care to adjust the spark plug correctly. Otherwise the motor can get too hot and get damaged.

Pump Maintenance

- Make a visual inspection of the pump every day. If noticing oil loss around the pump seals, take the Pressure Washer to a TRUPER Authorized Service Center to be repaired.

- Do not try to repair or alter the pump. Otherwise the Pump Washer could get damaged and the warranty will be void.

Maintenance

Long Term Storage

  • Connect and open the water supply. Keep the unit running until running out of fuel. Remember, gasoline gets spoiled after 30 days even with the recommended stabilizer.
    • After all the fuel is gone and the motor stops, turn off the switch and disconnect all the hoses, see they are empty and roll without twisting while the motor cools off (approximately 30 minutes).
  • Empty the pump. Pull the manual start jack-line handle 6 times approximately.
  • Replace oil as indicated in page 11.
  • Disconnect the spark plug and remove it. Pour less than a spoonful of 4-stroke clean motor oil through the spark plug orifice, into the combustion chamber.
  • Having the spark plug removed pull the manual start jack-line two or three times to cover the insides of the cylinder wall.
  • Service the plug before installing it back as indicated in page 11. Leave the spark plug cable disconnected.
  • Clean the air filter as indicated in page 11.

- Store the unit and accessories in an area under a roof, well ventilated and protected from freezing temperatures. Using an adequate cover is recommended if stored in low temperatures. Do not store it near furnaces or other heat sources because it makes the pump seals dry.

Using the Unit After Long Term Storage

  • Pull the start jack-line three to four times to clean the oil from the combustion chamber.
  • Remove the spark plug from the cylinder. Clean the oil in the spark plug and set it back into the cylinder.
  • Connect the spark plug cable.
  • Fill up as indicated in page 8.
