torque adjustment Collar (fig. 1)
Your tool has an adjustable torque screwdriver
mechanism for driving and removing a wide array of
fastener shapes and sizes and in some models, a
hammer mechanism for drilling into masonry. Circling
the collar (c) are numbers, a drill bit symbol, and on
some models, a hammer symbol. These numbers
are used to set the clutch to deliver a torque range.
The higher the number on the collar, the higher the
torque and the larger the fastener which can be
driven. To select any of the numbers, rotate until the
desired number aligns with the arrow.
