NOTE: Continuous use in variable speed range is not
recommended. It may damage the switch and should be
avoided.
Torque adjustment collar (Fig. A,D)
The torque adjustment collar (3) is clearly marked with
numbers and a drill bit symbol.The collar should be rotated
until the desired setting is located at the top of the tool.
Locators are provided 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 center line on the top ofthe tool. Failure to do
this will allow the clutch to slip while attempting to drill.
Gear shifter (Fig A, D)
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 (4) forward (towards
the chuck). To select the high speed, low torque setting, turn
the tool off and permit to stop. Slide the gear shifter back
(away from chuck).
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 E)
Your tool features a keyless chuck with one rotating sleeve for
one-handed operation of the chuck. To insert a drill bit or other
accessory, follow these steps.
1. Lock the trigger in the OFF position as previously
described.
2. Grasp the black sleeve of the chuck with one hand and
use the other hand to secure the tool. Rotate the sleeve
counterclockwise far enough to accept the desired
accessory.
3. Insert the accessory about 19 mm (3/4") into the chuck
and tighten securely by rotating the chuck sleeve
clockwise with one hand while holding the tool with the
other. Your tool is equipped with an automatic spindle lock
mechanism. This allows you to open and close the chuck
with one hand. To release the accessory, repeat step 2
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
(Original instructions)
chuck and personal injury may result. Always lock off trigger
switch when changing acces sories.
Be sure to tighten chuck with one hand on the chuck sleeve
and one hand holding the tool for maximum tightness.
Chuck removal (Fig F)
Turn the adjustment collar to the "drill" position and gear
shifter to position 1 (low speed). Tighten the chuck around the
shorter end of a hex key (not supplied) of 6.35 mm (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 Figure F.
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
Screw the chuck on by hand as far as it will go and insert
screw (left-hand thread). Tighten screw securely. Tighten the
chuck around the shorter end of a 6.35 mm (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.
DRILL OPERATION
WARNING: To reduce the risk of serious personal
injury, turn tool off and disconnect tool from power
source before making any adjustments or
removing/installing attachments or accessories.
WARNING: To reduce the risk of personal injury,
ALWAYS ensure workpiece is anchored or clamped
firmly. If drilling thin material, use a wood "back-up"
block to prevent damage to the material.
Turn the collar to the drill bit symbol for drilling. Select the
desired speed/torque range using the gear shifter to match the
speed and torque to the planned operation.
• Use sharp drill bits only. For WOOD, use twist drill bits,
spade bits, or hole saws. For METAL, use high-speed
steel (HHS) twist drill bits or hole saws.
• Always apply pressure in a straight line with the bit. Use
enough pressure to keep drill biting, but do not push hard
enough to stall the motor or deflect the bit.
• Hold tool firmly with both hands to control the twisting
action of the drill.
