slow speed to start the hole and accelerate by squeezing the trigger harder when the hole is deep enough to drill without the bit skipping out.
Drilling in Metal
Use a cutting lubricant when drilling metals. The exceptions are cast iron and brass which should be drilled dry. The cutting lubricants that work best are sulfurized cutting oil or lard oil;
Drilling in Wood
Holes in wood can be made with the same twist drills used for metal. These bits may over- heat unless pulled out frequently to clear chips from the flutes. For larger holes, use power drill wood bits. Work that is apt to splinter should be backed up with a block of wood.
Drilling in Masonry
Use carbide tipped masonry bits at low speeds. Keep even force on the drill but not so much that you crack the brittle materials. A smooth, even flow of dust indicates the proper drilling rate.
Bubble Level
Your drill is equipped with a bubble level that assists you in drilling level holes.
For horizontal drilling, tilt the drill up or down as required so that the bubble floats in the cen- ter of the parallel lines drawn on the glass. When the bubble is centered between the lines, as shown in Figure 3A, the drill is level.
For vertical drilling, align the drill so that the bubble floats in the center of the
To assure accuracy, first place a level on your work piece and position it so that it is level. Then, when the drill reads level, the two will be aligned. (Any bubble level can only indicate level to the earth’s surface).
NOTE: The level is filled with mineral oil that may cause minor skin irritation when contacted. If the level breaks and this fluid gets on your skin, rinse thoroughly with water. If any liquid gets in your eyes, rinse thoroughly with water and call a physician immediately.
Keyless Chuck (DW106)
Your tool features a keyless chuck for greater convenience. To insert a drill bit or other acces- sory, follow the steps listed below.
1.Unplug the drill.
2.Grasp the rear half of the chuck with one hand and use your other hand to rotate the front half counterclockwise, as shown in Figure 4. Rotate far enough so that the chuck opens sufficiently to accept the desired accessory.
3.Insert the bit or other accessory about 3/4" into the chuck and tighten securely by holding the rear half of the chuck and rotating the front portion in the clockwise direction.
To release the accessory, repeat step 2 listed above.
WARNING: Do not attempt to tighten drill bits (or any other accessory) by gripping the front part of the chuck and turning the tool on. Damage to the chuck and personal injury may result.

FIG. 3B
Tighten the chuck around the shorter end of a hex key (not supplied) of 1/4" or greater size. Using a soft hammer or piece of wood, strike the longer end in the counterclockwise direction, as shown in Figure 5.
This will loosen the chuck so that it can be unscrewed by hand.
Chuck Installation
Screw the chuck on by hand as far as it will go. Tighten the chuck around the shorter end of a 1/4" or larger hex key (not supplied) strike the longer end in the clockwise direction with a soft hammer, as shown in Figure 6.
Keyed Chuck (DW100,DW101)
Open chuck jaws by turning collar with fingers and insert shank of bit about 3/4" into chuck. Tighten chuck collar by hand. Place chuck key in each of the three holes, and tighten in clockwise direc- tion. It’s important to tighten chuck with all three holes. To release bit, turn chuck counter clockwise in just one hole, then loosen the chuck by hand.
Removal of Keyed Chuck
Place chuck key in any one of the three holes in the chuck, as shown in Figure 7. Strike the key sharply in the counterclockwise direction (when viewed from the front of the tool). This will loosen the chuck so that it can be removed by hand.
Keyed Chuck Installation
Screw the chuck on by hand as far as it will go. Insert the chuck key into one of the three holes and strike it in the clockwise direction with a soft hammer, as shown in Figure 8.
Lubrication
When the tool is taken apart for motor brush replacement a small amount of grease should be added (or redistributed from that remaining in housing) to the gears.
The ball bearings used in this tool are lubricated during manufacture and require no lubrica- tion.

RÈGLES DE SÉCURITÉ GÉNÉRALES
AVERTISSEMENT! Vous devez lire et comprendre toutes les instructions. Le non- respect, même partiel, des instructions
CONSERVEZ CES INSTRUCTIONS.
AIRE DE TRAVAIL
•Veillez à ce que l’aire de travail soit propre et bien éclairée. Le désordre et le manque de lumière favorisent les accidents.
•N’utilisez pas d’outils électriques dans une atmosphère explosive, par exemple en présence de liquides, de gaz ou de poussières inflammables. Les outils électriques créent des étincelles qui pourraient enflammer les poussières ou les vapeurs.
•Tenez à distance les curieux, les enfants et les visiteurs pendant que vous travaillez avec un outil électrique. Ils pourraient vous distraire et vous faire faire une fausse manoeuvre.
SÉCURITÉ ÉLECTRIQUE
•Les outils à double isolation sont équipés d’une fiche polarisée (une des lames est
plus large que l’autre), qui ne peut se brancher que d’une seule façon dans une prise polarisée Ne modifiez pas la fiche de l’outil. La double isolation 
élimine le besoin d’un cordon d’alimentation à trois fils avec mise à la terre ainsi que d’une prise de courant mise à la terre.
•Évitez tout contact corporel avec des surfaces mises à la terre (tuyauterie, radiateurs, cuisinières, réfrigérateurs, etc.) . Le risque de choc électrique est plus grand si votre corps est en contact avec la terre.
•N’exposez pas les outils électriques à la pluie ou à l’eau. La présence d’eau dans un outil électrique augmente le risque de choc électrique.
•Ne maltraitez pas le cordon. Ne transportez pas l’outil par son cordon et ne débranchez pas la fiche en tirant sur le cordon. N’exposez pas le cordon à la chaleur, à des huiles, à des arêtes vives ou à des pièces en mouvement. Remplacez immédiatement un cordon endommagé. Un cordon endommagé augmente le risque de choc électrique.
•Lorsque vous utilisez un outil électrique à l’extérieur, employez un prolongateur pour l’extérieur marqué
