ASSEMBLY
WARNING
To reduce the risk of injury, always
unplug tool before changing or
removing accessories. Only use accessories
specifically recommended for this tool. Others
may be hazardous.
To reduce the risk of injury, always use a side
handle when using this tool. Always brace or
hold securely.
Adjusting the Side Handle Position
1. Loosen the side handle by unscrewing the side
handle grip until the side handle rotates freely.
2. Rotate the side handle to the desired position.
3. Tighten the side handle grip securely.
Setting the Depth Gauge
1. Press in the clamping lever.
2. Slide the depth gauge rod backward or forward
until it is set for the desired depth.
NOTE:
The drilling depth is the distance between
the tip of the bit and the tip of the rod.
3. Release the clamping lever.
WARNING
To reduce the risk of injury, do not
grasp the bit while the chuck is
rotating or while the bit is falling from the chuck.
Installing Drill Bits and Chisels
Only use accessories with SDS or SDS Plus shanks.
Be sure that the shank of the bit is clean. Dirt particles
may cause the bit to line up improperly. Do not use
bits larger than the maximum recommended capacity
of the drill because gear damage or motor overload-
ing may result. For best performance, be sure that
the bit is properly sharpened and the shank is lightly
greased before use.
1. Insert the bit or chisel into the nose of the tool.
2. Rotate bit slowly until it aligns with the locking
mechanism.
3. Push bit into tool until it locks.
4. Check that the bit is locked
properly; it should be pos-
sible to pull the bit back and
forth slightly (about 1/4").
5. To remove bits and chisels,
pull bit holder release collar
toward the rear of tool and
remove bit.
NOTE:
Use caution when
handling hot bits and chisels.
