Operations
NOTE: The pilot may require repeated attempts to
ignite following initial installation or replacement of
the natural gas supply. The delay in ignition is due to
trapped air in the gas supply/pilot line.
1. Open gas supply valve.
2. Turn the gas valve ON/OFF knob to pilot position.
3. Fully depress gas ON/OFF knob and hold in.
Immediately push the igniter button down and
repeat until the pilot ignites. If the pilot fails to ignite
within 30 seconds, release the gas control knob,
depress slightly and turn to the OFF position. Wait
15 minutes and repeat steps 4 and 5.
4. Once pilot has ignited, continue to depress the gas
control knob for an additional 60 seconds before
releasing.
5. Turn gas control knob to the ON position.
6. Hold wand firmly, release trigger of trigger gun and
turn pump switch ON. Squeeze trigger of trigger
gun and allow air to purge from system.
7. If HOT water is desired, adjust the thermostat to
the proper temperature and turn burner switch ON.
Squeeze trigger of trigger gun. The pilot will auto-
matically light, quickly followed by the firing of the
burner ring. When the trigger of the trigger gun is
released or when the thermostat temperature
setting is reached, the burner will automatically
turn off.
IMPORTANT: If ignition or flame failure is experi-
enced, discontinue use of pressure washer at once.
Turn off burner and shut off fuel supply. Have
cause of failure corrected by an authorized service
technician before use of pressure washer is
continued.
To Clean
WARNING: Risk of injection or severe injury - Keep
clear of nozzle - DO NOT direct discharge stream at
persons - This machine is to be used only by
qualified operators.
AVERTISSEMENT: Risque d’injection et de
blessures graves. Se tenir à l’écart du jet. NE PAS
diriger le jet de sortie vers d’autres personnes.
Confier l’utilisation de ce matériel à un opérateur
qualifié.
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 that 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.
Turning the knob counterclockwise will pull
detergent into the system. The flow may be
observed through the clear detergent line. Secure
the knob position with the knurled nut.
4. The side control knob can now be adjusted to
meter the desired amount of detergent.
5. Select the width of your nozzle spray pattern by
turning the black knob on the nozzle. Pattern can
be from 0° through 80° fan spray.
6. Wash from the bottom to the top, using side to side
motions. This washes away heavy dirt and allows
the detergent to soak as you work toward the top.
7. Do not wash at a 90
o
angle to the work (straight at
it). This will allow water to splash back at you and
reduces your cleaning power. Wash at a 30
o
to 60
o
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.
8. Use the width of the spray pattern to wash in a
wide path. Overlap spray paths for complete
coverage. Wash from side to side, using slow,
steady motions.
9. 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.
10. Small parts should be washed in a basket so the
pressure does not push them away. Larger, light-
weight parts should be clamped down so the
pressure does not push them away.
11. 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 applica-
tion.
