OPERATION
USING THE PRESSURE WASHER
See Figure 19.
n Turn off the pressure washer and shut off the water
supply. Pull trigger to release water pressure.
n Engage the lock out on the trigger by pushing up on the
lock out until it clicks into the slot.
n Select the correct nozzle for the job:
• Use lower pressure nozzle (green or white) to wash
items such as a car or boat.
• Use higher pressure nozzle (red or yellow) for jobs such
as stripping paint and degreasing the driveway. When
using these nozzles, test a small area first to avoid
surface damage.
n Start at the top of the area and work down, overlapping
strokes. Keep all hoses away from the muffler.
For the most effective cleaning, the spray nozzle should be
between 8 in. and 4 in. from the surface to be cleaned.
If the spray is too close it can damage the cleaning
surface.
NOTE: See Washing with Detergent for detergent
application.
WASHING WITH DETERGENT
Use only detergents designed for pressure washers (house-
hold detergents, acids, alkalines, bleaches, solvents, flam-
mable material, or industrial grade solutions can damage
the pump). Many detergents require mixing prior to use.
Prepare cleaning solution as instructed on the solution bottle.
ALWAYS test detergents first in an area that is hidden.
n Place the injection hose in the bottom of the detergent
bottle/container. DO NOT run chemicals through the
inlet of the pump; use the chemical injection port only.
n Install the black nozzle on the spray wand .
n Spray the detergent on a dry surface using long, even,
overlapping strokes. To prevent streaking, do not allow
detergent to dry on the surface.
Keep all hoses away from
the muffler.
Before shutting off the engine:
n Place the injection hose in a bucket of clean water.
n Flush for 1 -  minutes (spray clear water through the spray
wand).
n Shut off the engine .
NOTE: Shutting OFF ( O ) the engine will not relieve pressure
in the system. Pull trigger to release water pressure.
See Using the Pressure Washer for rinsing instructions.
