DETERGENTS AND GENERAL OPERATING TECHNIQUES
PRESSURE WASHER
WARNING
STEP 2: Apply safety latch to spra y gun trigger. Secure
black detergent nozzle into quick coupler. NOTE: Detergent cannot be applied using Red, Yellow, Green or
White nozzles.
IMPORT ANT : You m ust 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.
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 3: With the engine 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.
pump protector engages and cools the pump by discharging the warm water onto the ground. This thermal
device prev ents 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 at low pressure (for best results , limit your work area to
sections approximately 6 feet square and alw a ys 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 dir t. 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 strok es
as you clean and rinse any surface. For best surf ace cleaning action spray at a slight angle.
Recommendations:
• Before cleaning any surf ace, an inconspicuous area
should be cleaned to test spray pattern and distance for maximum cleaning results.
• If painted surfaces are peeling or chipping, use e xtreme caution as pressure washer may remo ve the
loose paint from the surface.
• Keep the spra y nozzle a saf e distance from the surface you plan to clean. High pressure wash a small
area, then check the surface f or damage. If no damage is found, continue to pressure washing.
CAUTION - Never use:
• Bleach, chlorine products and other corrosive
chemicals
These chemicals will harm the machine and will damage the surface being cleaned.
RINSING
• It will take a fe w seconds f or the detergent to clear .
Apply safety latch to spray gun. Remov e black soap
nozzle from the quick coupler . Select and install the
desired high pressure nozzle. NOTE: Y ou can also
stop detergent from flowing by simply removing detergent siphon tube from bottle.

THERMAL PUMP PROTECTION
If you run the engine on your pressure washer for 3-5
minutes without pressing the trigger on the spray gun,

CAUTION
If you must store your pressure washer in a location
where the temperature is below 32° F, you can minimize the chance of damage to your machine by draining your machine as follo ws:
1. Stop the pressure washer and detach supply hose
and high pressure hose. Squeez e the trigger of the
spray gun to drain all water from the wand and
hose.
2. Restart pressure washer and let it run briefly (about
5 seconds) until water no longer discharges from

PREVENTATIVE MAINTENANCE
This pressure washer was produced with the best av ailable materials and quality craftsmanship. Howe ver , you as
the owner have certain responsibilities for the correct care of the equipment. Attention to regular preventative
maintenance procedures will assist in preserving the performance of your equipment. Contact your dealer for
maintenance. Regular preventativ e maintenance will add many hours to the life of y our pressure washer . P erform
maintenance more often under severe conditions .

General InspectionInspect the motor at regular intervals, approximately every 500 hours of operation,
or every 3 months, whichever occurs first. K eep the motor clean and the ventilation
openings clear. The following steps should be perf ormed at each inspection:
WARNING: Do not touch electrical connections before you first ensure that power
has been disconnected. Electrical shock can cause serious or f atal injury . Only qualified personnel should attempt the installation, operation and maintenance of this
equipment.
1. Chec k that the motor is clean. Check that the interior and exterior of the motor
is free of dirt, oil, grease, water, etc. Oily vapor , paper pulp , te xtile lint, etc. can
accumulate and block motor v entilation. If the motor is not properly ventilated
overheating can occur and cause early motor failure .
2. Check all electrical connectors to be sure that they are tight.
Lubrication & BearingsBearing grease will lose its lubricating ability over time, not suddenly. The lubricating
ability of a grease (over time) depends primarily on the type of grease, the size of the
bearing, the speed at which the bearing operates and the severity of the operating
conditions. Good results can be obtained if the following recommendations are used in
your maintenance program.
Type of GreaseA high grade ball or roller bearing grease should be used. Recommended greases
standard service conditions are: Shell Dolium R (Factory installed) or Chevron SRI
