Motors for all models: 110-253
Volt, Frequency 45-66 Hz, max. power 2000 Watt

* In order to be able to loosen bolts please
add 20 % on top of the max. required tightening
torque. Continuous operation at maximum load
will activate the thermal overload protection
and shut off the tool.

- Detailed description |
Locking pin for use of the machine as rigid
version (fixed joint motor/gearbox)
One-handed operation, four-edge operation button
for clock wise, counter clock wise, toggle start
and start commands
|
-
Primary operation unit:
on/off switch of the machine; One-handed operation:
comfortable, slow right/left rotation for
safe and precise positioning of the torque
wrench (toggle switch) as well as for the
starting of the bolt tightening process.
-
Speed, frequency and torque
are correspondingly regulated and controlled.
Microcontrolled monitoring combined with a
processor controlled switch-off electronic
guarantee a precise repeatability of the pre-set
torque. Repeatable accuracy for shutoff is
+/- 5% for identically soft and hard joints.
- Integrated motor protection: for safety reasons
an automatic thermal overload switch is built
in as well as a permanent cooling fan that keeps
running after the safety shutoff and thus provides
short periods of cooling.
- Two principles of construction within one
tool:
A = swivelling: free joint tool - the drive
unit (motor) can independent of the gear box
be fully rotated even when the reaction arm
is already in its position
B = Rigid: Fixed joint between motor and gear
box - mechanically reversible

Secondary operation unit
- Type EFC
LED-Display: light-emitting diode displays
the pre-set torque within 19 stages together
with the direction of rotation
