REMOVING BITS (Fig. 12)
1. Remove the battery pack
2. Lock the trigger switch on
the drill/driver by placing the
direction-of-rotation selector
in the center position.
3. Open the chuck jaws.
4. Rotate the chuck in the
direction of the arrow marked
RELEASE to loosen the
chuck jaws.
NOTICE: Do not use a wrench to tighten or loosen the chuck jaws.
5. Remove the bit.
ѥ
WARNING: Use protective gloves when removing the bit from the tool, or
first allow the bit to cool down. The bit may be hot after prolonged use.
DRILLING (Fig. 13)
1. Check that the direction-
of-rotation selector is at
the correct setting (forward
or reverse).
2. Secure the material to be
drilled in a vise or with clamps
to keep it from turning as the
drill bit rotates.
3. 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 as the hole is started.
4. When drilling metals, use light oil on the drill bit to keep it from overheating.
The oil will prolong the life of the bit and increase the drilling action.
5. Hold the drill/driver firmly, and place the bit at the point to be drilled.
6. Depress the trigger switch to start the drill/driver.
7. Move the drill bit into the workpiece, applying only enough pressure to
keep the bit cutting. Do not force the drill/driver or apply side pressure to
elongate a hole. Let the tool do the work.
8. If the bit jams in the workpiece or if the drill/driver stalls, stop the tool
immediately. Remove the bit from the workpiece and determine the reason
for jamming.
