Detergents & General Cleaning
Techniques
WARNING: Some detergents may
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 detergent.
Place the filter end of detergent
suction tube into the detergent
container
.
STEP 2: Apply safety
latch to spray gun trigger.
Open variable pressure
wand handle to low
pressure which allows
water through black
detergent nozzle.
NOTE: Detergent cannot
be applied during high
pressure.
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 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 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.
