Tightening a Fastener
For most fastening operations, make sure the screwdriver turns clockwise when running forward. For
left-hand fastening capable screwdrivers, make sure the screwdriver turns counterclockwise when
running forward.
Once the screwdriver is positioned on a part, you begin the rundown (cycle start) by:
• Pressing the trigger lever on handheld screwdrivers that have the push-to-start function disabled
OR
• Pressing the trigger lever on handheld screwdrivers that have the push-to-start function enabled,
then pushing down firmly on the screwdriver
OR
• Asserting (activating) the remote start input on fixtured screwdrivers
The cycle start signal must remain active in order to complete the rundown. If the signal is interrupted
- if you release the trigger lever, for example - the screwdriver stops immediately.
When the rundown is complete, you can see the status of the rundown by:
• The illumination of the LEDs on the screwdriver - green for acceptable torque/angle, yellow for
low torque/angle, and red for high torque/angle
• The controller display
• VS software displays the final torque/angle
NOTE:
?
For details of asserting (activating) remote inputs and reading
the controller display, refer to the appropriate controller manual.
