Lever Start with Shut-off Clutch
The pneumatic tools have a torque-dependent shut-off
clutch with a wide adjusting range. The clutch disengages
when the set torque is reached.
– To switch on the pneumatic tool, press lever 9 and keep it
pressed during the working procedure.
– The pneumatic tool switches off automatically when
reaching the set torque.
When the lever 9 is released too early, the preset torque is not

Setting the Torque

0 607 451 60. (see figure I1)
– Place the locking hook 25 into the slot in the housing 5.
– Hold the tool holder 1 in place with an open-end wrench or
Allen key.
– Set the torque using the locking hook 25.
Turning in the clockwise direction results in a higher torque, in
the counterclockwise direction, a lower torque.
Start with low setting values.
– Remove the open-end wrench or Allen key and the locking
hook.
0 607 452 60./... 453 62. (see figure I2)
– Turn the protective sleeve 6, until an elongated hole be-
comes visible in the housing.
– Turn the tool holder 1 with an open-end wrench or Allen
key until a semi-circular recess becomes visible in the ad-
justment disc 26.
– Insert the adjustment tool 27 into the recess.
Turning in the clockwise direction results in a higher torque, in
the counterclockwise direction, a lower torque.
Start with low setting values.
– Remove the adjustment tool 27 and turn the protective
sleeve until it can be felt to engage.
0 607 457 60. (see figure I3)
– Remove the locking screw 15.

Note: Do not mistake the slot with the flat side of the round
nut 28.
– Insert the locking hook 25 into the slot and lock the clutch
29.
– Twist the clutch 29 using the open-end wrench or tighten
the tool holder 1 in a vice and set the torque by turning the
pneumatic tool.
Turning in the clockwise direction results in a higher torque, in
the counterclockwise direction, a lower torque.
Start with low setting values.
– Remove the open-end wrench and the locking hook.
– Screw in the locking screw.
After Setting the Torque
Note: For soft screwdriving applications, the safety clutch
does not disengage for low torque settings.
– Adapt the torque to the respective screwdriving applica-
tion (hard, medium, soft) through practical testing.
– Check the torque with an electronic torque measuring de-
vice or a torque wrench.
Set Angled Drive Head
The angled drive head 2 with tool holder 1 is continuously ad-
justable by 360°. You can fasten the screwdriver in the spec-
ified clamping area 8.
0 607 451 60./... 453 62. (see figure J1)
– Loosen the union nut 3 with an open-end wrench.
– Turn the angled drive head 2 to the desired work angle, but
not more than once by 360°.
– Tighten the union nut again.
0 607 452 60. (see figure J2)
– Loosen the lock nut 4 by inserting an appropriate tool into
an opening of the lock nut and turning the lock nut in the di-
rection of the arrow a (left thread).
– Turn the angled drive head 2 in arrow direction b until the
desired work angle is reached, but not more than once by
360°.
– Fix the angled drive head 2 in this position by turning the
lock nut 4 in the direction of the arrow c against the angled
drive head. Tighten the lock nut 4 with a tightening torque
of max. 80 Nm again.
0 607 457 60. (see figure J3)
It is advisable to clamp the tool holder 1 in a vice.
– Loosen the union nut 3 to about half of the thread of the
screwdriver by hooking a hook wrench in the opening of
the union nut and turning rightwards.
– Pull the angled drive head 2 from the screwdriver, set the
desired work angle and push the drive head back.
– Screw the union nut 3 back on and tighten it with the hook
wrench.

Working Advice

Sudden loads cause a sharp drop in speed or a complete stop,
yet do not cause damage to the motor.
