OPERATION
REMOVING BITS
See Figure 10.
Lock the switch trigger by placing the direction of
rotation selector in the center position. Open the chuck jaws.
NOTE: Rotate the chuck body in the direction of the arrow marked UNLOCK to open the chuck jaws. Do not use a wrench to tighten or loosen the chuck jaws.
Remove the drill bit.
DRILLING
Check the direction of rotation selector for the correct
setting (forward or reverse).� |

Secure the material to be drilled in a vise or with clamps |
| |
to keep it from turning as the drill bit rotates.� | WRONG | |
Hold the drill firmly and place the bit at the point to be | ||

drilled.� |

Depress the switch trigger to start the drill.
Move the drill bit into 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.
WARNING:
Be prepared for binding at bit breakthrough. When these situations occur, drill has a tendency to grab and kick opposite to the direction of rotation and could cause loss of control when breaking through material. If not prepared, this loss of control can result in possible serious injury.
When drilling hard, smooth surfaces, use a center punch to mark the desired hole location. This will prevent the drill bit from slipping
When drilling metals, use a 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.
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.
NOTE: This drill has an electric brake. When the switch trigger is released, the chuck stops turning. When the brake is functioning properly, sparks will be visible through the vent slots on the housing. This is normal and is the action of the brake.
