DETERGENTS & GENERAL CLEANING TECHNIQUES
WARNING: Some detergents
WARNING
may be harmful if inhaled or
ingested, causing severe nau-
sea, fainting or poisoning. The
harmful elements may cause
property damage or severe
injury.
STEP 1: Use detergent de-
signed specifically for pressure
washers. Household detergents
could damage the pump. Pre-
pare detergent solution as re-
quired by the manufacturer. Fill a
container with pressure washer
detergent. Place the filter end of
detergent suction tube into the
detergent container.

machine. Liquid detergent is drawn into the machine
and mixed with water. Apply detergent to work area.
Do not allow detergent to dry on surface.
IMPORTANT: You must flush the detergent injection
system after each use by placing the suction tube
into a bucket of clean water, then run the pressure
washer in low pressure for 1-2 minutes.
THERMAL PUMP PROTECTION
If you run your pressure washer for 3-5 minutes with-
out pressing the trigger on the spray gun, circulating
water in the pump can reach high temperatures.
When the water reaches this temperature, the pump
protector engages and cools the pump by discharg-
ing the warm water onto the ground. This thermal
device prevents internal damage to the pump.
CLEANING TIPS
Pre-rinse cleaning surface with fresh water. Place
detergent suction tube directly into cleaning solu-
tion and apply to surface at low pressure (for best
results, limit your work area to sections approxi-
mately 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

STEP 2: Apply safety latch
to spray gun trigger. Se-
cure black detergent nozzle
into quick coupler. NOTE:
Detergent cannot be applied

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 dam-
age. If no damage is found, continue to pressure
washing.
CAUTION - Never use:
• Bleach, chlorine products and other corrosive
chemicals
• Liquids containing solvents (i.e., paint thinner,
gasoline, oils)
• Tri-sodium phosphate products
• Ammonia products
• Acid-based products
These chemicals will harm the machine and will
damage the surface being cleaned.
RINSING
It will take a few seconds for the detergent to clear.
Apply safety latch to spray gun. Remove black soap
nozzle from the quick coupler. Select and install the
desired high pressure nozzle.
NOTE: You can also stop detergent from flowing by
simply removing detergent siphon tube from bottle.
