Operating The Screwdriver; Setting The Torque - Bossard 035/E32V Operator's Manual

3.4 OPERATING THE SCREWDRIVER

All models have a forward/reverse switch.
Grip the screwdriver so that the index finger is comfortably over the trig-
ger (Start Lever) mechanism and the thumb can be used to change the
position of the fwd/rev switch if required. Hold securely to prevent the
screwdriver from rotating in the hand during use.
Familiarize yourself with the operation of the tool by free running the tool
before use at higher torque values.
Align the driver installation equipment properly with the head of the
fastener. Keeping the driver in line with the fastener, activate and hold
the start mechanism (lever, trigger, or push). The screwdriver will ins-
tall the fastener (FWD). When the pre-set torque is reached, the clutch
will activate and the tool will shut off. Once the tool shuts off, release
the start mechanism to reset. To stop the screwdriver before fastening is
complete, release the start mechanism.
To remove a fastener, change the FWD/REV switch to the REV position.
Press the start mechanism to run the screwdriver in reverse (CCW).
Do not switch from forward to reverse (or reverse to forward) while the
motor is running. A protective circuit will stop the tool if it is inadvertently
switched while running – if this happens, the trigger must be released and
reactivated to continue operation.

3.5 SETTING THE TORQUE

An external torque adjustment nut located at the nose of the screwdriver is used to set the output torque
of the screwdriver. A reference scale (0-8) is available as a guide – this scale is for reference only and
does not indicate actual torque values. Rotate the torque nut clockwise to increase torque output, ccw
to decrease torque output. Make the torque adjustment through a series of gradual increases, starting
below the desired torque level. We recommend the use of an appropriate torque tester and static joint
testing after installation to verify proper torque settings. Once the torque is set, remove the housing nut
and cover the torque adjustment nut with the included torque lock sleeve. This will help avoid accidental
torque adjustments. The torque output of the screwdriver should be verified on a regular basis. Frequency
of verification will depend on the customer's specific application and quality control requirements. During
the initial screwdriver break-in period, output torque may decay somewhat as the mechanical components
wear in.
