damaging the tool.
• Different values of torque are
applied to various types of screws
loosening and
be automatically
and materials.
• The higher is the number
corresponding to a given posit on,
the higher is the torque (fig. B).
• Set the torque control ring (2) to
a specified amount of torque.
• The work should be started with
a lower value of torque.
• The torque should be increased
gradually until satisfying results
are obtained.
• Higher settings should be used
to tighten screws.
• Settings marked with a drill bit
symbol must be used for drilling.
The highest value of torque is
obtained in this setting.
• The ability to select proper torque
settings is gained along with with
