Direction of Rotation Selector (FORWARD/REVERSE/CENTER LOCK)

The direction of bit rotation is reversible and is controlled by a selector located above the switch trigger. With the drill held in normal operating position, the direction of rotation selector should be positioned to the left of the switch trigger for forward drilling. The drilling direction is reversed when the selector is to the right of the switch trigger.

Setting the switch trigger in the OFF (center lock) position helps reduce the possibility of accidental starting when not in use.

Operation

[Caution] To prevent gear damage, always allow the chuck to come to a complete stop before changing the direction of rotation.

To stop the drill, release the switch trigger and allow the chuck to come to a complete stop.

NOTE: The drill will not run unless the direction of rotation selector is pushed fully to the left or right.

Avoid running the drill at low speeds for extended periods of time. Running at low speeds under constant usage may cause the drill to become overheated. If this occurs, cool the drill by running it without a load and at full speed.

Keyless Chuck

The drill has a keyless chuck to tighten or release bits in the chuck jaws. The arrows on the chuck indicate which direction to rotate the chuck body in order to LOCK (tighten) or UNLOCK (release) the bit.

WARNING: Do not hold the chuck with one hand and use the power of the drill to tighten the chuck jaws on the bit. The chuck body could slip in your hand, or your hand could slip and come in contact with the rotating bit. This could cause an accident resulting in serious personal injury.

• Insert the bit.
• WARNING: Make sure to insert the bit straight into the chuck jaws. Do not insert the bit into the chuck jaws at an angle then tighten, as shown in figure 9. This could cause the bit to be thrown from the drill, resulting in possible serious personal injury or damage to the chuck.
• Tighten the chuck jaws securely on the bit.
• NOTE: Rotate the chuck body in the direction of the arrow marked LOCK to close the chuck jaws. Do not use a wrench to tighten or loosen the chuck jaws.

Removing Bits

• 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 bit.

Drilling

A level is located on the top of the motor housing to help keep the drill bit level during use.

• 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.
• 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 off-center as the hole is started.
• 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.

Wood Drilling

For maximum performance, use high speed steel bits for wood drilling.

• Begin drilling at a very low speed to prevent the bit from slipping off the starting point. Increase the speed as the drill bit bites into the material.
• 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

For maximum performance, use high speed steel bits for metal or steel drilling.

• Begin drilling at a very low speed to prevent the bit from slipping off the starting point.
• Maintain a speed and pressure which allows cutting without overheating the bit. Applying too much pressure will:
  • Overheat the drill;
  • Wear the bearings;
  • Bend or burn bits; and
  • Produce off-center or irregular-shaped holes.
• When drilling large holes in metal, start with a small bit, then finish with a larger bit. Also, lubricate the bit with oil to improve drilling action and increase bit life.

Maintenance

Chuck Removal

The chuck may be removed and replaced by a new one.

• Lock the switch trigger by placing the direction of rotation selector in center position.
• Insert a 5/16 in. or larger hex key into the chuck of the drill and tighten the chuck jaws securely.
• Tap the hex key sharply with a mallet in a clockwise direction. This will loosen the screw in the chuck for easy removal.
• Open the chuck jaws and remove the hex key.
• Using a screwdriver, remove the chuck screw by turning it in a clockwise direction.

NOTE: The chuck screw has left hand threads.

• Insert the hex key into the chuck and tighten the chuck jaws securely. Tap sharply with a mallet in a counter-clockwise direction. This will loosen the chuck on the spindle. It can now be unscrewed by hand.

To Retighten a Loose Chuck

The chuck may become loose on the spindle and develop a wobble. Also, the chuck screw may become loose, causing the chuck jaws to bind and prevent them from closing.

To tighten:

• Lock the switch trigger by placing the direction of rotation selector in the center position.
• Open the chuck jaws.
• Insert the hex key into the chuck and tighten the chuck jaws securely. Tap the hex key sharply with a mallet in a clockwise direction. This will tighten the chuck on the spindle.
• Open the chuck jaws and remove the hex key.
• Apriete el tornillo del portabrocas girándolo hacia la izquierda con un destornillador.
