powder view chamber (8) located on the side of the
unit will show that the powder remains stationary.
This indicates that powder is not being delivered to
the spray head and the unit can be used for rinsing in
this mode. When pressure is removed from the foot
control, a short delay ensures that the head is
thoroughly flushed with air alone to prevent irritating
clogging. This is normal.
Important: Dental units with automatic oiler systems for low speed
handpieces need to be bypassed or eliminated. Ask your full service
dealer if you are not sure if your unit is equipped with this feature. A
clean dry air supply is required to prevent clogging.
Powder Only airpolishing powder consisting of specially
formulated sodium bicarbonate, such as JETSTREAM
POWDER™ should be used in your Jetpolisher
2000 unit because it is specially formulated for this
purpose.
Shake the powder prior to refilling unit and always store powder with
lid secured to prevent caking. Fresh powder should be used if the
unit has not been in use for a few days.
Important: Always use the special funnel (4) provided to prevent
spilling of powder inside the unit during filling. Do not fill with
powder above the bottom edge of the funnel.
The "Finger- CORRECT ADJUSTMENT FOR POLISHING
tip Test"
The mode selector switch (2) is pushed into the
polishing mode position. Activation of the unit by
pressure on the foot control in this mode will result in
powder being delivered to the spray head and powder
turbulence being observed in the viewing chamber (8).
This stream of air and powder is mixed with the water
stream and results in a patented homogenous stream
of air, water and powder, (H.S.T.®polishing system)
unique to the Jetpolisher 2000, being emitted from
the nozzle.
The correct mixture of air, water and powder results in
a spray with minimum scatter and most economical
use of powder, and is achieved as follows: The water
control knob (5) is fully opened, the nozzle is held
approximately 1 cm (3/8") from the finger tip (fig. 1)
and while maintaining constant pressure on the foot
control, the water control knob (5) is turned slowly so
as to reduce the amount of water in the stream.
