DRILLING
– cont’d
The workpiece to be drilled should be
secured in a vice or with clamps to keep it
from turning as the drill bit rotates (Fig. 8).
1. Check drill bit to make sure it is firmly
locked into the SDS clamp or drill
chuck and the forward / reverse switch
is in the forward position.
2. Hold the tool firmly with both hands
whenever possible. Use one hand to
grasp the handle and switch and the
other to grasp the body of the tool.
NOTE: Make sure the hand placed on the
body of the tool does not cover the air
vents. Covering these air vents will reduce
the motor cooling and possibly lead to
overheating the motor.
3. While holding the tool firmly, place the
point of the drill bit at the point to be
drilled. Depress the switch trigger to
start the drill.
4. Move the drill bit into the workpiece
applying only enough pressure to
keep the bit cutting. Do not force the
drill bit or apply sideways pressure to
elongate the hole.
WARNING:
Be prepared for
binding and bit breakthrough. When
these situations occur, the drill bit has
the tendency to grab the workpiece.
This action will kick the tool 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 possible serious injury.
