INSTALLING/REMOVING BITS

See Figures 4 – 5,

The arrows on the keyless chuck indicate which direction to rotate the chuck sleeve to tighten or release the drill bit.
Do not use a wrench to tighten or loosen the chuck jaws.

To install bits, lock the switch trigger.
Open or close the chuck jaws until the opening is slightly larger than the bit size you intend to use.
Raise the front of the hammer drill slightly and insert the drill bit.

WARNING:
Make sure to insert the drill bit straight into the chuck jaws. Do not insert the drill bit into the chuck jaws at an angle, then tighten. This could cause the drill bit to be thrown from the hammer drill, resulting in possible serious personal injury or damage to the chuck.

Rotate the chuck sleeve to close and tighten the chuck jaws.

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

If the hammer drill is not in use, the time-out feature will cause the light to start fading and then shut off.
The LED light illuminates only when there is a charged battery pack in the tool.

TWO-SPEED GEAR TRAIN
See Figures 7 and 8,

Select low speed (1) for applications such as drilling in metal, and for applications requiring higher torque, such as driving large screws.
Select high speed (2) for fast drilling or driving applica-tions, for drilling in wood or masonry, and for hammer drilling.
NOTICE:
Never change speeds while the tool is running. Failure to obey this caution could result in serious damage to the hammer drill.

NOTE: If you have difficulty changing from one speed range to the other, turn the chuck by hand until the gears engage.

ADJUSTING TORQUE/DRIVING SCREWS

See Figures 9 and 10,

When using the hammer drill for various driving applica-tions, increasing or decreasing the torque helps prevent the possibility of damaging screw heads, threads, workpiece, etc. In general, torque intensity should correspond to the screw diameter. If the torque is too high or the screws too small, the screws may be damaged or broken. The torque is adjusted by rotating the torque adjustment ring.
The torque is greater when the torque adjustment ring is set on a higher setting. The torque is less when the torque adjustment ring is set on a lower setting.
Rotate the adjustment ring to the proper torque setting for the type of material and size of screw you are using.

1 – 4 For driving small screws
5 – 8 For driving screws into soft material
9 – 12 For driving screws into soft and hard materials
13 – 16 driving screws into hard wood
17 – 22 For driving large screws
For drilling
For drilling into masonry and concrete.

WARNING:
Do not drive a screw where there is likely to be hidden wiring behind the surface. Contact with a “live” wire will make exposed metal parts of the tool “live” and possibly shock the operator. If you must drive a screw where hidden wire may be present, always hold tool by insulated gripping surfaces (handle) when performing the operation to prevent a shock to the operator.

Depress the switch trigger to start the hammer drill.
Move the bit into the workpiece, applying only enough pressure to keep the bit cutting or driving the screw. Do not force the drill or apply side pressure to elongate a hole. Let the tool do the work.

WARNING:
When drilling, be prepared for binding at bit break-through. 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 bit from slipping off-center as the hole is started.
If the bit jams in the workpiece or if the hammer drill stalls, stop the tool immediately. Remove the bit from the workpiece and determine the reason for jamming.
NOTE: This hammer drill has an electric brake. When the switch trigger is released, the chuck stops turning.
NOTE: If operation creates considerable dust, frequent vacuuming of the work area is recommended.

WOOD AND METAL DRILLING

For maximum performance, use high speed steel bits for wood or metal .gnillirdSelect drilling mode by rotating the torque adjustment ring to the drill bit icon. Begin drilling at a very low speed to prevent the bit from slipping off the starting point.

Wood Drilling.

Select drill mode.
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 and Steel Drilling

Select drill mode.
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.
Maintain a speed and pressure which allows cutting without overheating the bit. Applying too much pressure will:
- Overheat the hammer drill;
- Wear the bearings;
- Bend or burn bits; and
- Produce off-center or irregularly.shaped hole
When drilling large holes in metal, start with a small bit, then finish with a larger bit.

MASONRY DRILLING
For maximum performance, use carbide-tipped masonry impact bits or designated hammer drill bits when drilling holes in brick, tile, concrete, etc.

Select hammer mode.
Apply light pressure at medium speed for best results in brick
Apply additional pressure for hard materials such as Conctrete
When drilling holes in the tile, practice on a scrap piece to determine the best speed and pressure. Begin drilling at a very low speed to prevent the bit from slipping off starting points
