OPERATING INSTRUCTIONS
DRILLING (Fig. 15)
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.

to be drilled.
4. Depress the trigger switch to start the drill/driver.
5. 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.
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.

8. To stop the drill/driver, release the trigger switch and allow the tool to come to a complete stop.
The electric brake quickly stops the rotation. This feature engages automatically when you
release the trigger switch.
NOTE: This drill/driver 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.
WOOD DRILLING
1. For maximum performance, use high-speed steel or brad-point bits for drilling wood.
2. Begin drilling at a very low speed to prevent the bit from slipping off the starting point.
3. Increase speed as the drill bit bites into the material.
4. When drilling "through" holes, place a block of wood behind the workpiece to prevent ragged or
splintered edges on the back side of the hole.
METAL DRILLING
1. For maximum performance, use high-speed steel bits for drilling metal or steel.
2. 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.
3. Begin drilling at a very low speed to prevent the bit from slipping off the starting point.
4. Maintain a speed and pressure which will allow cutting without overheating the bit. Applying too
much pressure will:
- Overheat the drill/driver.
- Wear the bearings.
- Bend or burn bits.
- Produce off-center or irregular-shaped holes.
