(motor BL (4) or motor BL ISO (5)) replaces the air drive
port (for highspeed handpieces or air-driven motors)
previously used on the dental treatment center.
It is connected and controlled solely via the hose coupling (6a) of the air-driven instrument.
Control is effected by means of the pneumatic foot
switch (A) which is available on the unit side. Power
is supplied by an external transformer (12).
Site of installation
Mount the SIROTorque L+ (1) at an easily accessible
location on top of or adjacent to the dentist element of
the treatment center.
Be sure to choose the installation site of the
SIROTorque L
connected to the dentist element with the previously
used highspeed handpiece or air motor hose (6).
Ensure that the unit has a safe and stable stand.

The connecting cable (7) between the transformer (12)
and the SIROTorque L+ (1) must be run in such a way
that it can not be damaged by moving appliances such
as chairs with wheels, carts, etc.:
• Place the transformer (12) directly next to the supply
unit (C).
• Run the connecting cable (7) so that it does not
touch the floor anywhere. To do this, use the
adhesive cable clamps (D) supplied.
• Run the connecting cable (7) in such a way that it
cannot be damaged at the supply unit.
• Install the power cable (13) of the transformer as
required by the relevant national regulations.

Connection to the supply hose
Push back the cap nut (1) and insert the small tubes and
contact pins of the motor in the supply hose coupling (2)
as far as they will go.
The arrow on the hose coupling must line up with the
notch on the motor (A).
Make sure that the pins and small tubes are inserted
properly (i.e. are not bent).
First press the cap nut (1) gently onto the thread; then
turn it counterclockwise until a faint click can be heard.
Only then should you screw it onto the motor hand-tight.

During preparation work, a sufficient amount of cooling
media (water component > 50 ml/min) must always be
available. Insufficient cooling leads to overheating of the
cavity and to damage to the tooth substance.
Please always make sure that the flow rate is
sufficient!

5 Operation
ATTENTION
Make sure that the compressed air is always dry, clean
and not contaminated. Dirty or humid compressed air
leads to premature wear of the motor.
Permissible speed range: 90 – 40,000 rpm
The compressed air emitted at the highspeed handpiece
hose connection piece should have a pressure of
at least 44 psi (3 bar) to enable the electric motor to
reach its maximum speed.
ATTENTION
The displayed speed is an approximate value. The actual
speed may differ from the displayed speed.
If you need an accurate speed, you should operate the
motor at a speed close to 40,000 rpm and use the corresponding contra-angle handpieces.
e.g. desired speed: 347 rpm.
– Set motor to 40,000 rpm.
– Use reduction gear instrument (115 : 1).

Setting the gear ratio
Attach the selected straight/contra-angle handpiece to
the motor.
ATTENTION
Be sure to compare the gear ratio of the straight/
contra-angle handpiece you're using with the
"Gear Ratio" display reading. If these two values are not
identical, the burr speed display reading is not correct,
since it is calculated by multiplying the motor speed by
the gear ratio.
Set the gear ratio of the attached straight/contra-angle
handpiece with the +/- keys (20).
This is also possible when the motor is running.
Preselection of the gear ratio occurs in the following
order. The most popular straight/contra-angle handpieces appear first
