DIRECTION OF ROTATION SELECTOR
(FORWARD/REVERSE/CENTER LOCK)
See Figure 3, page 10.
Set the direction of rotation selector in the OFF (center lock)
position to lock the switch trigger and help prevent accidental
starting when not in use.
Position the direction of rotation selector to the left of the
switch trigger for forward drilling. Position the selector to the
right of the switch trigger to reverse the direction.
NOTE: The drill will not run unless the direction of rotation
selector is pushed fully to the left or right.
NOTICE:
To prevent gear damage, always allow the chuck to
come to a complete stop before changing the direction
of rotation.
TWO-SPEED GEAR TRAIN (HIGH-LOW)
See Figure 4, page 11.
 Select low (1) speed for applications requiring higher
power and torque.
 Select high (2) speed for fast drilling or driving applications.
NOTICE:
Never change speeds while the tool is running. Failure
to obey this caution could result in serious damage to
the 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
See Figure 5, page 11.
There are 24 torque indicator settings located on the front
of the drill.
 Rotate the adjustment ring to the desired setting.
• 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 For driving screws into hard wood
• 17 - 23 For driving large screws
• For drilling or high-torque applications
INSTALLING / REMOVING BITS
See Figures 6 - 8, page 11.
Using the chuck:
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.
OPERATION
 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 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 drill, resulting in possible serious per-
sonal 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 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.
 To remove bits, lock the switch trigger and open the
chuck jaws.
 The bit provided with the drill can be placed in the storage
area, located on the base of the drill.
Using the chuck collet:
The chuck collet has been designed to accept 1/4 in. hex bits.
NOTE: Use only 2 in. or larger bits with a locking groove.
To install:
 Lock the switch trigger.
 Remove the battery pack.
 Open the chuck jaws until the chuck collet can be accessed.
 Push the bit into the chuck collet until it clicks into place.
 Pull gently on the bit to make sure it is secured in the
chuck collet. There may be some play in the installed bit;
this is normal.
NOTE: If there is too much play in the installed bit when
using the chuck collet, rotate the chuck sleeve to close
and tighten the chuck jaws.
WARNING:
Make sure the bit is secured in the chuck collet before
using the tool. Failure to do so could cause serious per-
sonal injury.
