Type of Clutch
The machines have a torque depend-
ent S-Plus clutch that is adjustable
over a wide range. It reacts when the
torque setting is reached.
Bypassing the Disengagement
The switching off of the torque can be
bypassed by pressing the lever 11 in
order to screw into materials of differ-
ent hardness (e.g., wood with knots).
Applications: Sheet metal screws
Wood screws
Dismantling areas
Thrust and Lever Start with S-Plus Clutch
Thrust Start
Switching on: Apply axial pressure to the tool.
Switching off: The machine switches off automatically
when the torque setting is reached.
When additional torque is required, the S-Plus can be
activated (switch-off bypass) by means of the lever
start device.
Lever Start
Switching on: Press the lever 11.
switch-off is by-passed and an over-
load clutch reacts instead.
Switching off: Release the lever 11.
When the actuation lever (lever start) or the
tool pressure (thrust start) is released prema-
turely, the torque setting will not be reached!

Working Instructions

Before performing any work on the machine it-
self, disconnect the air supply.
Setting the Torque
(Figures and )
A B
Turn the protective sleeve 3 until a slot is visible in the
housing.
Turn the tool holder 1 with a 1/4" Allen key until a
half-round cut-out in the adjustment disk 13 is visi-
ble.
Insert the adjustment tool 12 in the cut-out.
Turning in the clockwise direction results in a higher
torque, in the counter clockwise direction, a lower
toque.
Remove the adjustment tool. Turn the protective collar
until it can be heard to latch.
Caution!
For soft bolting actions, the clutch no longer
ratchets even for low torque settings.
II–4
After the adjustment
Adapt the torque by means of trial boltings for the spe-
cific bolting action (hard, middle, soft). Check the
torque with an electronic torque measuring instrument
or a torque wrench.
For higher torques, a correspondingly greater
counter force is necessary.
With a clamping device in the area 4, this counter
force can more easily be counteracted.
Machines that are operated with a torque greater than
4 Nm are to be used with a clamping device or an aux-
iliary handle.
Take care that the auxiliary handle or the clamping de-
vice holds the unit in a firm and secure manner.
Reversing Rotational Direction
Right rotation: Right/Left rotation button 9
Left rotation: Right/Left rotation button 9 pressed.

Replacing the Spring
In case work is performed with lower torques (approx.
0.6 – 2.5 Nm) than given in the product specifications,
the spring 22 can be replaced with a white spring.
