Incoming goods inspection and packaging
Check the device and accessories for transport damage. If any damage is detected, please
notify the carrier immediately and return the device in its original packaging to InnoTorc or the
responsible sales partner. Please retain the original packaging.
Read these instructions before putting the device into service and make yourself familiar with
the procedure for handling it. Do not use the device if you are unsure of the purpose, the
consequences and the precise execution of the specific operation.
In particular, make yourself familiar with the safety instructions. Failure to observe them may
result in severe bodily harm.

Safety precautions prior to commissioning and assembling the
device
Each time you use the device and accessories, inspect them for any damage. Devices that are
damaged or defective must not be put into service. Repairs may only be performed by the
manufacturer. Send any defective/damaged devices back to the manufacturer in the original
packaging.
Check whether the available mains voltage supply matches the data on the identification plate.
Only use the device for its intended purpose.
The noise level may exceed 85 dB(A) so you must always wear ear protection.
Observe any local, industry-specific regulations, such as the wearing of safety footwear,
helmets, gloves, etc.
Do not use the device in an explosive atmosphere or in the presence of inflammable liquids,
gases, paints, vapours or dust.
Do not use the device in rain or other damp conditions.
Before you insert the battery, assemble the socket and the support arm in accordance with the
illustration above. The socket together with the pin and the support arm must be fixed with the
screw. Make sure that these parts are correctly and completely in position. Do not use any
defective or damaged accessories.

Safety precautions and performing the tensioning operation
[RICHTIG = CORRECT; FALSCH = WRONG]
Never hold the device at the front by the socket or support arm due to the risk of crushing and
other injuries! Under no circumstances should you reach into the space between support arm
and support point.
Set the desired torque. A power reserve of approx. 25% should be allowed for loosening bolts.
The socket must be placed completely onto the head of the bolt and must not be tilted. The
transmission axis must be in line with and not deviate from the axis of the bolt.
The support arm must rest securely on the adjacent bolt or on another fixed point. The
supporting point must be at the same height as the bolt. The support arm must be resting on
the vertical side surfaces.
Never block the operating button with any kind of aid. Always be ready to switch it off.
Only press the trigger switch lightly while the support arm is not firmly positioned on the
resting point so that the device is able to turn slowly. Do not press the trigger switch to its
maximum extent until the wrench is firmly in position.
The wrench switches off when the preset torque has been attained. Now set the direction of
rotation to the left and run the device until the support arm is free.

Controls, setting torque
Set the desired torque using the calibration certificate: first determine the gear and setting with
the aid of the tables on the last page of the calibration certificate. Then select the gear by
means of the black sliding switch. Gear 1 is the slowest speed and Gear 4 the fastest. The
sliding switch must not be positioned in the centre but has to fully click into place; otherwise
the device will jam. Only change the gear when the device is not moving.
The required setting (1 to 15) is adjusted by means of the rotary knob with the numbers.
Setting 1 has the lowest torque for the selected gear and setting 15 the highest torque.
Intermediate settings, e.g. between 3 and 4, are not possible.
Gear 4 is only intended for the fast rotation of loose screws and bolts, not for screw
connections relevant to quality. Consequently, Gear 4 is not usually calibrated.

Controls, setting direction of rotation
The diamond-shaped reversing switch is indicated on either side with an arrow for the specific
direction of rotation. Pressing the reversing switch changes the direction of rotation, see
Figure. Make sure that the reversing switch has clicked firmly into place to the extreme left or
right. Only change the direction of rotation when the device is not moving.
Trigger switch on the front of the handle. Pressing the trigger switch starts up the device and
releasing it stops the device. The device also stops when the preset torque has been attained.
If you only press the trigger switch lightly, the motor only rotates slowly. Only when the trigger
switch is depressed completely will the maximum speed be attained.
The silver locking ring between the wrench and gearbox allows the gearbox to be rotated and
locked in a specific position. Pulling the ring towards the motor allows the gearbox to be
adjusted to the site conditions in 12 steps of 30° (degrees). After adjusting the device, make
sure it has clicked securely back into place. Failure to observe this precaution may lead to high
recoil torques delivered to the handle of the tensioning device.
