2. Open the chuck jaws.
NOTICE:
Rotate the chuck body in the direction of the arrow marked OPEN
to close the chuck jaws. Do not use a wrench to tighten or loosen the chuck
jaws.
3. Remove the drill bit.
USING THE AUXILIARY HANDLE ASSEMBLY
WARNING:
To reduce the risk of injury, always use the auxiliary handle
when operating and hold tool with both hands to maximize control.
The auxiliary handle must be tightened sufficiently to resist the twisting
action of the tool if the bit binds or stalls. Be sure to grip the side handle at
the far end to control the tool during a stall.
The auxiliary handle can be attached to either side for left- or right-hand use.
GENERAL DRILLING (Fig. 12)
1. Check the direction of rotation
selector for 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. Hold the drill firmly and place the bit
at the point to be drilled.
4. Depress the trigger switch to start the drill.
5. Move the drill bit to contact the workpiece, applying only enough pressure
to keep the bit cutting. Do not force the drill or apply side pressure to
elongate a hole. Let the tool do the work.
6. 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.
7. 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.
8. If the bit jams in the workpiece or if the drill stalls, stop the tool
immediately. Remove the bit from the workpiece and determine the
reason for jamming.
NOTICE:
This drill is equipped with an electric brake. When the brake is
functioning properly, sparks may be visible through the vent slots in the
housing. This is normal and is the action of the brake.
DRILLING MODE OPERATION
1. Select the desired speed to match the planned operation.
