TECHNIQUES
Warning: Pressure washers produce a kickback. To
prevent personal injuries due to falls use auxiliary
safety equipment.
The detergent injector valve operates by reducing the
volume of water, thus a vacuum is achieved and detergent
is drawn into the system. DO NOT reduce the water inlet
flow so much as the pump cavitates because of water
starvation. Operating a pump with insufficient water will
damage the pump seals.
1. Insert detergent line and screen into container of
detergent.
2. Completely open detergent control knob located on
the side of the detergent injector valve.
3. Start the detergent suction by rotating the water
adjustment knob of the detergent injector valve. See
Figure 5. Turning the knob counterclockwise will pull
detergent into the system. The flow may be observed
4. The side control knob can now be adjusted to meter
the desired amount of detergent.

5. Do not wash at a 90
it). This will allow water to splash back at you and
reduces your cleaning power. Wash at a 30
angle to the work. This will allow the water to splash
away from you and the water will wash the dirt away
faster and easier.
6. Use the width of the spray pattern to wash in a
wide path. Overlap spray paths for complete cover-
age washing from side to side, using slow, steady
motions.
7. The nozzle should be 12" to 24" from work, closer for
tough areas. Be careful on painted or delicate surfaces,
the pressure may damage surface if nozzle is too close.
8. Small parts should be washed in a basket so the pres-
sure does not push them away. Larger, lightweight
parts should be clamped down so the pressure does
not push them away.

9. Turn the side detergent control knob clockwise (CW)
for detergent decrease. Wait for detergent to clear.
Always rinse with cold water after using detergent.
Rinse from the top to the bottom to prevent detergent
from dripping onto a rinsed area. For the best results,
contact your Hotsy dealer to help you select the best
detergent for your application.
STORAGE & MAINTENANCE

STORAGE

Protect from freezing by storing in a heated area, or by
flushing the system with antifreeze (use an automotive
engine antifreeze or windshield washer solvent to
antifreeze). To flush the system with antifreeze, attach
a short length of hose to the garden hose connector
located on the pump. Place the other end of the hose into
a container of antifreeze. Start machine and allow to run
until antifreeze flows from the end of the wand. 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 Exploded View 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 flushed with
antifreeze for rust protection.
