Installing a Bit or Accessory into a Keyless
Chuck (Fig. H)

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 and disconnect tool from power source when
changingacces sories.

WARNING: Always ensure the bit is secure before
starting the tool. A loose bit may eject from tool
causing possible personalinjury.
To insert a drill bit or other accessory, follow thesesteps.
1. Turn tool off and remove batterypack.
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 3/4" (19 mm) into the
chuck
4
and tighten securely by grasping and rotating
the chuck sleeve clockwise with one hand while
holding the tool with the other. When the chuck is
nearly tightened you will hear a clicking sound. After
12-14 clicks the chuck is securely tightened around
the accessory. Your tool is equipped with an automatic
spindle lock mechanism. This allows you to open and
close the chuck with onehand.
Be sure to tighten chuck with one hand on the chuck sleeve
and one hand holding the tool for maximumtightness.
To release the accessory, repeat steps 1 and 2above.
Side Handle (Fig.A)

WARNING: To reduce the risk of personal injury,
ALWAYS operate the tool with the side handle properly
installed. Failure to do so may result in the side handle
slipping during tool operation and subsequent loss of
control. Hold tool with both hands to maximizecontrol.
Side handle
7
clamps to the front of the gear case and may
be rotated 360° to permit right- or left-hand use. Side handle
must be tightened sufficiently to resist the twisting action
of the tool if the accessory binds or stalls. Be sure to grip the
side handle at the far end to control the tool during astall.
