Driving Screws
When driving screws, use the proper
screwdriver bit for your job. After drilling
pilot and shank holes, start the screw
slowly and increase the speed as driving
progresses. Set the screw by slowing to
a stop. Do not run screws down at exces-
sive speeds. To remove screws, reverse
the motor.
Stalling
If the tool seems as if it is about to stall,
maintain a firm grip and reduce pressure
slightly to allow the bit to regain speed. If
the tool does stall, release the trigger im-
mediately. Reverse the motor, remove the
bit from the work and start again. Do not
pull the trigger on and off in an attempt to
start a stalled drill. This can damage the
drill.
WARNING!
High rotational force. To reduce
the risk of injury, always hold or
brace securely. Always use side
handle on tools rated 1200 rpm or
less.
Bit Binding
A high rotational force occurs when a bit
binds. If the bit binds, the tool will be forced
in the opposite direction of the bit rotation
(See Fig. 12-14). Bits may bind if they are
misaligned or when they are breaking
through a hole. Wood boring bits can also
bind if they run into nails or knots. Be pre-
pared for bit binding situations.
To reduce the chance of bit binding:
• Use sharp bits. Sharp bits are less likely
to bind when drilling.
• Use the proper bit for the job. There are
bits that are designed for specific
purposes.
• Use caution when drilling pitchy, knotty,
wet or warped material or when drill-
ing in material that may contain nails.
