CautIOn:
To prevent gear damage, always allow
the chuck to come to a complete stop before chang-
ing the direction of rotation.
To stop the drill, release the switch and allow the chuck to
come to a complete stop.
nOte: The drill will not run unless the direction of rotation
selector is pushed fully to the left or right.
Avoid running the drill at low speeds for extended periods
of time. Running at low speeds under constant usage may
cause the drill to become overheated. If this occurs, cool
the drill by running it without a load and at full speed.
WarnInG:
Always unplug the tool when installing
or removing bits, adjusting settings, or when the tool
is not in use. Failure to unplug the tool may result in
accidental starting and serious personal injury.

 To lock the spindle, depress and hold the spindle lock
button.
 While keeping the button depressed, rotate the chuck
clockwise until the spindle clicks into a locked position
and will not rotate further.
 To unlock, release the button.
nOte: Always be sure the spindle lock button is released
and the spindle lock is disengaged before turning the drill
On.
InstallInG BIts
See Figure 3, page i.
 Unplug the drill.
 Lock the spindle.
 Rotate the chuck sleeve clockwise to open the chuck
jaws.

 Release the spindle lock.
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, as shown in
figure 4. This could cause the drill bit to be thrown
from the drill, resulting in possible serious personal
injury or damage to the chuck.
 Rotate the chuck counterclockwise to tighten the
chuck jaws securely on the bit.
nOte: Rotate the chuck body in the direction of the
arrow marked lOCK to tighten the chuck jaws.

An auxiliary handle is packed with the drill for ease of
operation and to help prevent loss of control. The handle
can be rotated 360° and it can also be mounted on the
opposite side for left hand use.
To adjust the auxiliary handle assembly, loosen the handle
assembly by turning the handle counterclockwise.
Rotate the auxiliary handle assembly to the desired
operating position.
Securely tighten by turning the auxiliary handle clockwise.
Be sure the auxiliary handle is securely tightened. This
secures the depth stop rod in the depth stop clamp at the
desired depth of cut. It also secures the auxiliary handle.
nOte: For convenience and ease of starting threads, the
hex nut has been trapped inside the molded slot in the
auxiliary handle.
The depth stop rod helps control the depth of drilled
holes.
nOte: When properly installed, the teeth on the depth
stop rod should be aligned with the teeth indicator on the
depth stop clamp.
Adjust the depth stop rod so that the drill bit extends
beyond the end of the rod to the required drilling depth.
When drilling holes with the depth stop rod installed, the
desired hole depth has been reached when the end of the
rod comes in contact with the surface of the workpiece.
