OPERATION
1 . Check the direction-of-rotation selector
for the correct setting (forward or
reverse) .
2 . Use a vise or clamps to secure the
material to be drilled to keep it from
turning as the drill bit rotates .
3 . Hold the cordless drill/driver firmly, and
place the bit at the point to be drilled .
4 . Depress the trigger switch to start the
cordless drill .
5 . Move the drill bit into the workpiece,
applying only enough pressure to keep
the bit cutting .
6 . Do not force the cordless drill/driver or
apply sideways pressure to elongate a
hole . Allow the tool to do the work .
7 . When drilling hard, smooth surfaces,
use a center punch to mark the desired
location of the hole . This will prevent the
drill bit from slipping off-center when
the hole is started .
8 . When drilling metal, use light oil on the
drill bit to prevent it from overheating .
The oil will prolong the life of the bit and
will increase the drilling efficiency .
9 . If the bit jams in the workpiece or if
the drill/driver stalls, stop the tool
immediately . Reverse the direction of
rotation and gently squeeze the trigger
to remove the bit from the workpiece .
Investigate and correct the cause of
jamming before resuming work .
WARNING:
Be prepared for binding
when the bit breaks through the workpiece,
because the drill/driver has a tendency
to grab and kick opposite to the direction
of rotation, which could cause a loss of
control . If the operator is not prepared, this
loss of control could result in serious injury .
REMOVING A bIT (FIG. 11a)
1 . Lock the trigger switch by placing the
direction-of rotation selector in the OFF
(center) position .
2 . Open the jaws of the chuck (rotate in the
“OPEN” direction .)
3 . Remove the drill bit .
GENERAL DRILLING (FIG. 12)
WARNING:
Always wear safety
goggles or safety glasses with side shields
during power tool operation or when
blowing dust . If the operation is dusty, also
wear a dust mask .
