Detergent Use; Transporting - Westinghouse WPX3400 User Manual

OPERATION

DETERGENT USE

The use of detergents can dramatically reduce cleaning
time and assist in the removal of difficult stains. Many
detergents are customized for pressure washer use for
specific cleaning tasks. When spraying detergent, the
detergent will be diluted 1:12. Approximately 621 ml (21
oz.) of detergent will be consumed from the tank for every
minute sprayed.
Only use detergents designed for pressure washers.
Pressure washer detergents are as thick as water. Using
thicker detergents, like dish soap, will clog the chemical
injection system. Do not use household detergents,
acids, alkalines, bleaches, solvents, flammable material,
or industrial grade solutions, which can damage the
pump or cause property damage.
Prepare cleaning solution as instructed on the solution
bottle. Always test in an inconspicuous area before
beginning. You can effectively clean surfaces by combining
the chemical action of detergents with high pressure rinses.
On vertical surfaces, apply the detergent starting at the
bottom and work your way upward. This method prevents
the detergent from sliding down and causing streaks.
Begin high pressure rinsing at the bottom and work your
way upward. On particularly tough stains, use a brush in
combination with detergents and high pressure rinsing.
1. Fill the detergent tank with cleaning solution.
2. Install the detergent nozzle (black) in the spray lance.
Detergent will only be drawn through the pump when
the black detergent nozzle is attached to the end of the
spray lance.
3. Make sure the water supply is ON. Start the engine. Pull
the trigger to spray the detergent solution.
NEVER use bleach in detergent tank. It will damage the
pump and void the warranty.
4. Use long, even overlapping strokes to apply soap. Allow
3 – 5 minutes for the soap to soak in before rinsing. Do
not allow the soap to dry on the surface before rinsing.
Reapply soap if necessary to maintain a wet surface for
the soap to soak in.
DETERGENT SYSTEM FLUSH
The detergent suction system can be flushed by removing
the suction tube from the detergent tank and placing the
tube in a fresh bucket of water. Only perform a system
flush when the detergent tank is empty.

NOTICE
NOTICE
1. With the water supply ON, the black nozzle connected to
the spray gun lance, and the engine running, disconnect
the suction tube from the bottom of the detergent tank.
2. Place the suction tube in a clean bucket of water,
disengage the trigger lock, then depress the spray gun
trigger to flush the system.
3. Engage the trigger lock then reinstall the suction tube on
the detergent tank.
AFTER EACH USE
1. Lock the spray gun trigger.
2. Turn the engine OFF, then turn the water supply OFF.
3. Disengage the trigger lock and depress the trigger for
15 seconds to depressurize the system.
4. Let the pressure washer cool down.
5. Disconnect the high-pressure hose and water inlet hose.
6. Drain the hoses, spray gun, and nozzle extension.
7. Engage the trigger lock on the spray gun.
8. Wipe off all remaining water with a clean, dry rag.
9. While the pressure washer is turned off, pull the recoil
handle 5 - 6 times. This should remove most of the
remaining liquid inside the pump.
10. Store the pressure washer in a clean, dry place.

TRANSPORTING

Weight hazard. Always have assistance when lifting the
pressure washer.
• Allow the pressure washer to cool a minimum of 30
minutes before transporting.
• Only use the pressure washer's fixed frame to lift the
unit or attach any load restraints such as ropes or tie-
down straps. Do not attempt to lift or secure the pressure
washer by holding onto any of its other components.
• Keep the unit level during transport to minimize the
possibility of fuel leakage or, if possible, drain the fuel
or run the engine until the fuel tank is empty before
transport.
• The pressure washer wheels are only intended for hand
transport. The wheels are not suitable for towing the
pressure washer either on or off-road.
