OPERATION
CHANGING THE NOZZLE
See Figure 16.
Pull back the quick-connect collar at the end of the spray
lance. Insert the nozzle then release the collar. Pull on the
nozzle to make sure it is secured.
SPRAYING TIPS
For most cleaning, keep nozzle 8 - 24 in. (20 - 61 cm) away
from cleaning surface.
l Damage may occur to the cleaning surface if you spray
too close, especially with high-pressure nozzles.
l When beginning to spray, start farther away and move
closer to avoid damage to the surface.
l To prevent damage to tires, allow at least 6 in. (15 cm)
between a tire and the nozzle.
DETERGENT USE
See Figure 17.
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.
NOTICE
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, bleach-
es, 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 begin-
ning. 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.
l Fill the detergent tank with cleaning solution.
l 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.
l Make sure the water supply is ON. Start the engine. Pull
the trigger to spray the detergent solution.
NOTICE
NEVER use bleach in detergent
tank. It will damage the pump and void the warranty.

l 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.
l 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.
l Place the suction tube in a clean bucket of water, disen-
gage the trigger lock, then depress the spray gun trigger
to flush the system.
l Engage the trigger lock then reinstall the suction tube on
the detergent tank.
AFTER EACH USE
l Lock the spray gun trigger.
l Turn the engine OFF, then turn the water supply OFF.
l Disengage the trigger lock and depress the trigger for
15 seconds to depressurize the system.
l Let the pressure washer cool down.
