DRILLING – cont’d
WARNING: Be prepared for
binding and bit breakthrough. When
these situations occur, the drill bit has a
tendency to grab the workpiece. This
action will kick the drill opposite to the
direction of drill bit rotation, and could
cause loss of control when breaking
through material as you complete
drilling the hole. If you are not prepared,
this loss of control can result in serious
injury.
When drilling metals, use a light oil on the
drill bit to keep it from overheating. The oil
will prolong the life of the drill bit and
improve the cutting action. If the bit jams in
the workpiece, or if the drill stalls, release
the trigger switch immediately. Remove the
bit from the workpiece and determine the
reason for jamming.
DRIVING SCREWS
When driving screws, care must be taken
to use the bit that correctly fits the screw
being driven. Make sure you use the
largest bit size that will properly fit into the
head of the screw.
1. Select the correct screwdriver bit for
the screw being driven.
2. Fasten the screwdriver bit into the
chuck, making sure the flat sides of
the bit are gripped by the chuck jaws.
3. Set the torque clutch to the
appropriate setting based on the chart
on Page 17.
