PRESSURE WASHER
OPERATOR’S MANUAL
Pre-rinse cleaning surface with fresh water. Place de-
tergent suction tube directly into cleaning solution and
apply to surface at low pressure (for best results, limit
your work area to sections approximately 6 feet square
and always apply detergent from bottom to top). Allow
detergent to remain on surface 1-3 minutes. Do not
allow detergent to dry on surface. If surface appears
to be drying, simply wet down surface with fresh water.
If needed, use brush to remove stubborn dirt. Rinse at
high pressure from top to bottom in an even sweeping
motion keeping the spray nozzle approximately 1 foot
from cleaning surface. Use overlapping strokes as you
clean and rinse any surface. For best surface cleaning
action spray at a slight angle.
Recommendations:
• Before cleaning any surface, an inconspicuous
area should be cleaned to test spray pattern and
distance for maximum cleaning results.
• If painted surfaces are peeling or chipping,
use extreme caution as pressure washer may
remove the loose paint from the surface.
• Keep the spray nozzle a safe distance from the
surface you plan to clean. High pressure wash a
small area, then check the surface for damage. If
no damage is found, continue to pressure wash-
ing.
CAUTION - Never use:
• Bleach, chlorine products and other corrosive
chemicals
• Liquids containing solvents (i.e., paint thinners,
gasoline, oils)
• Tri-sodium phosphate products
• Ammonia products
• Acid-based products
These chemicals will harm the machine and will dam-
age the surface being cleaned.
GENERAL CLEANING TECHNIQUES & STORAGE
RINSING
It will take a few seconds for the detergent to clear.
Apply safety latch to spray gun. Select and install de-
sired high pressure nozzle.
NOTE:
You can also stop
detergent from fl owing by removing detergent siphon
tube from bottle.
STORAGE
DANGER: DO NOT store
fl
ammable liquids (gasoline,
diesel fuel, solvents, etc.) near pressure washer, or in
non-ventilated areas.
Protect from freezing by storing in a heated area, or by
fl ushing the system with antifreeze (use an automotive
engine antifreeze or windshield washer solvent to
antifreeze). To fl ush the system fi ll the fl oat tank with
antifreeze and remove pressure nozzle from wand. Start
the machine and allow it to run until antifreeze fl ows from
the end of the wand. Place end of wand into fl oat tank
and circulate the antifreeze through system for several
minutes. Squeeze and release the trigger of the trigger
gun several times to antifreeze the unloader system.
Also draw antifreeze through the detergent inlet line to
antifreeze the detergent system. For added protection
after anti-freezing, disconnect the pressure hose from
machine and remove the coil drain plug (refer to
Figure
12
Item 15 for location). After coil has drained, replace
pressure hose and coil drain plug. If the pressure washer
is not to be used for an extended length of time, it is
recommended that the system be fl ushed with antifreeze
for rust protection.
