OPERATION

Instructions for Use

WARNING: Always observe the safety instructions and
applicable regulations.

WARNING: To reduce the risk of serious personal
injury, turn tool off and disconnect battery pack
before making any adjustments or removing/
installing attachments or accessories. An accidental
start-up can cause injury.

Screwdriver Operation (Fig. C)
1. Select the desired speed/torque range using the
three-speed gear shifter
the torque adjustment collar
gear shifter to speed 2 or 3. This ensures effective control
over the fastener allowing the screw to be seated correctly
and set to specification. Speed 1 will provide the same
clutching torque as speeds 2 and 3. However, for optimum
performance of the electronic clutch, speeds 2 and
3 are preferred.
nOTE: Use the lowest torque setting (1) first and increase
the number through to the highest setting (11) to seat the
fastener at the desired depth. The lower the number, the
lower the torque output.
2. Reset the torque adjustment collar
number setting for the torque desired. Make a few practice
runs in scrap or unseen areas to determine the proper
position of the torque adjustment collar.
nOTE: The torque adjustment collar may be set to any number
at any time.
