To install the bit, place it in the chuck as far as it will go.
Tighten the chuck by hand. Place the chuck key in each
of the three holes and tighten clockwise. Be sure to
tighten all three chuck holes evenly.
To remove the bit, turn the chuck key counterclockwise in
just one hole, then loosen the chuck by hand.
After using the chuck key, be sure to return to the original
position.
Depth gauge (optional accessory)
The depth gauge is convenient for drilling holes of
uniform depth. Loosen the side grip and insert the depth
gauge into the hole in the side grip. Adjust the depth
gauge to the desired depth and tighten the side grip.
NOTE:
• The depth gauge cannot be used at the position
where the depth gauge strikes against the tool
body.

Always use the side grip (auxiliary handle) and firmly
hold the tool by side grip and switch handle during
operations.
When drilling a large hole with a hole saw, etc., the side
grip (auxiliary handle) should be used as a brace to
maintain safe control of the tool.
Grasp the rear handle and the front grip firmly when
starting or stopping the tool, since there is an initial and
final reaction.
When drilling action is forward (clockwise), the tool
should be braced to prevent a counterclockwise reaction
if the bit should bind. When reversing, brace the tool to
prevent a clockwise reaction. If the bit must be removed
from a partially drilled hole, be sure the tool is properly
braced before reversing.
Drilling operation
Drilling in wood
When drilling in wood, the best results are obtained with
wood drills equipped with a guide screw. The guide
screw makes drilling easier by pulling the bit into the
workpiece.
