Applying Detergent &

General Operating Techniques

WARNING: Some detergents may
WARNING
be harmful if inhaled or ingested,
causing severe nausea, fainting or
poisoning. The harmful elements
may cause property damage or
severe injury.
STEP 1: Use detergent designed
specifically for pressure washers.
Household detergents could damage
the pump. Prepare detergent solution
as required by the manufacturer. Fill a
container with pressure washer deter-
gent. Place the filter end of detergent
suction tube into the detergent
container.
STEP 2: Open detergent valve counterclockwise until
you obtain desired mixture. Detergent will mix with the
high pressure water stream.
STEP 3: With the motor running,
pull trigger to operate 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 from
your pressure washer after each use by placing the
suction tube into a bucket of clean water, then run
the pressure washer for 1-2 minutes.
NOTE: If you remove detergent siphon tube from
container or allow container to empty, it will cause low
pressure by sucking air, which will damage the pump.

Thermal Pump Protection
If you run the engine for 3-5 minutes without 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 discharging 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 solution
and apply to surface. 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 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
Turn detergent valve clockwise to close. Operate
pressure washer and allow a few seconds for the
detergent to clear.
