READ ALL OF THE INSTRUCTIONS IN THE BATTERY CHARGER MANUAL BEFORE
ATTEMPTING TO CHARGE THE BATTERY PACK FOR YOUR TOOL.
Always use correct battery pack (pack supplied with tool or upgrade to an XR pack.) Never install
any other battery pack. It will ruin your tool and may create a hazardous condition.
Variable Speed Switch (Fig. 4)
To turn the tool on, squeeze the trigger switch (A). To turn the tool off, release the trigger switch.
Your tool is equipped with a brake. The chuck will stop as soon as the trigger switch is fully
released.
The variable speed switch enables you to select the best speed for a particular application. The
farther you squeeze the trigger, the faster the tool will operate. Use lower speeds for starting
holes without a centerpunch, drilling in metals or plastics, driving screws and drilling ceramics,
or in any application requiring high torque. Higher speeds are better for drilling in wood, wood
compositions and for using abrasive and polishing accessories. For maximum tool life, use vari-
able speed only for starting holes or fasteners.
NOTE: Continuous use in variable speed range is not recommended. It may damage the switch
and should be avoided.
Forward/Reverse Control Button (Fig. 4)
A forward/reverse control button (B) determines the direction of the tool and also serves as a
lock off button. To select forward rotation, release the trigger switch and depress the
forward/reverse control button on the right side of the tool.To select reverse, depress the for-
ward/reverse control button on the left side of the tool. The center position of the control button
locks the tool in the off position. When changing the position of the control button, be sure the
trigger is released.
NOTE: The first time the tool is run after changing the direction of rotation, you may hear a click
on start up. This is normal and does not indicate a problem.
Torque Adjustment Collar (Fig. 5)
The torque adjustment collar (A) is clearly marked with numbers and a drill bit symbol.The col-
lar should be rotated until the desired setting is located at the top of the tool. Locators are pro-
vided in the collar to eliminate the guess work when selecting fastening torque. The higher the
number on the collar, the higher the torque and the larger the fastener which can be driven. To
lock the clutch for drilling operations, move to the drill bit position.
NOTE: When using the Drill/Driver for drilling holes, be sure that the Torque Adjusting Collar is
set so the figure of the drill is aligned with the arrow on the top of the tool. Failure to do this will
allow the clutch to slip while attempting to drill
Dual Range Gearing (Fig. 5)
The dual range feature of your Driver/Drill allows you to shift gears for greater versatility.
To select the low speed, high torque setting, turn the tool off and permit to stop. Slide the gear
shifter (B) forward (towards the chuck) (position 1), as shown. To select the high speed, low
torque setting, turn the tool off and permit to stop. Slide the gear shifter back (away from chuck,
position 2).
NOTE: Do not change gears when the tool is running. If you are having trouble changing gears,
make sure that the dual range gear shifter is either completely pushed forward or completely
pushed back.
Keyless Chuck (Fig. 6)
Your tool features a keyless chuck for greater convenience. To insert a drill bit or other acces-
sory, follow the steps listed below.
1. Lock the trigger switch in the off position as described.
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 Fig. 6. Rotate far enough so that the chuck opens suffi-
ciently 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.
Always lock off trigger switch when changing accessories.
Be sure to tighten chuck with two hands on both the rear sleeve and the forward sleeve for max-
imum tightness.
Chuck Removal (Fig. 7)
Always wear eye protection.
Turn the adjustment collar to the "drill" position and low speed gear shifter to position 1. Tighten
the chuck around the shorter end of a hex key (not supplied) of 1/4" or greater size. Using a
wooden mallet or similar object, strike the longer end in the clockwise direction, as shown. This
will loosen the screw inside the chuck.
Open chuck jaws fully, insert screwdriver (or Torx tool if required) into front of chuck between
jaws to engage screw head. Remove screw by turning clockwise (left-hand-thread). Place hex
key in chuck and tighten, as shown in Fig. 8. Using a wooden mallet or similar object, strike key
sharply in the counterclockwise direction. This will loosen the chuck so that it can be unscrewed
by hand.
Chuck Installation (Fig. 8)
Screw the chuck on by hand as far as it will go and insert screw (LH thread). Tighten screw
securely. 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 wooden mallet, as shown. Tighten the
screw once again by turning in a counterclockwise direction.
Operation as a Drill
Turn the collar to the drill bit symbol. Install and tighten the desired drill bit in the chuck. Select
the desired speed/torque range using the dual range gear shifter to match the speed and torque
to the planned operation. Follow these instructions for best results when drilling.
DRILLING
1. Use sharp drill bits only. For WOOD, use twist drill bits, spade bits, power auger bits, or hole
saws. For METAL, use high speed steel twist drill bits or hole saws. For MASONRY, such
as brick, cement, cinder block, etc., use carbide-tipped bits.
2. Be sure the material to be drilled is anchored or clamped firmly. If drilling thin material, use
a "back-up" block to prevent damage to the material.
3. Always apply pressure in a straight line with the bit. Use enough pressure to keep the drill bit
biting, but do not push hard enough to stall the motor or deflect the bit.
4. Hold tool firmly to control the twisting action of the drill.
5. IF DRILL STALLS, it is usually because it is being overloaded. RELEASE TRIGGER
IMMEDIATELY, remove drill bit from work, and determine cause of stalling. DO NOT CLICK
TRIGGER OFF AND ON IN AN ATTEMPT TO START A STALLED DRILL – THIS CAN
DAMAGE THE DRILL.
6. To minimize stalling or breaking through the material, reduce pressure on drill and ease the bit
through the last fractional part of the hole.
7. Keep the motor running when pulling the bit back out of a drilled hole. This will help prevent
jamming.
8. With variable speed drills there is no need to center punch the point to be drilled. Use a 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. Operate at full on after starting the bit.
Drilling in Wood
Holes in wood can be made with the same twist drills used for metal. These bits may overheat
unless pulled out frequently to clear chips from the flutes. For larger holes, use low speed wood
bits. Work that is likely to splinter should be backed up with a block of wood.
Drilling in Metals
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 sulphurized cutting oil or lard oil; bacon
grease will also serve the purpose.
Drilling 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.
Operation as a Screwdriver
Select the desired speed/torque range using the dual range gear shifter on the top of tool to
match the speed and torque to the planned operation.
Insert the desired fastener accessory into the chuck as you would any drill bit. Make a few prac-
tice runs in scrap or unseen areas to determine the proper position of the clutch collar.
Maintenance
CLEANING: With the motor running, blow dirt and dust out of all air vents with dry air at least
once a week. Wear safety glasses when performing this. Exterior plastic parts may be cleaned
with a damp cloth and mild detergent. Although these parts are highly solvent resistant, NEVER
use solvents.
