Tool Assembly - Milwaukee 1680-20 Operator's Manual

To reduce the risk of injury, always unplug
tool before attaching or removing accessories
or making adjustments. Use only specifically
recommended accessories. Others may be
hazardous.
Installing Bits into Keyed Chucks (Fig. 1)
Fig. 1
1. Unplug tool.
2. Open the chuck jaws wide enough to insert the bit. Be sure the bit
shank and chuck jaws are clean. Dirt particles may prevent the bit
from lining up properly.
3. Insert the bit into the chuck. Center the bit in the chuck jaws and lift
it about 1/16" off of the bottom. Tighten the chuck jaws by hand to
align the bit.
4. Place the chuck key in each of the three holes in the chuck, turning
it clockwise to tighten the chuck securely.
NOTE: Never use a wrench or means other than a chuck key to
tighten or loosen the chuck.
5. To remove the bit, insert the chuck key into one of the holes in the
chuck and turn it counterclockwise.
Bit Selection
• Use sharp bits. Sharp bits are less likely to bind when drilling.
• Use the proper bit for the job. There are many types of bits designed
for specific purposes. Check the information on the bit's packaging
for proper usage.
• Do not use bits larger than the rated capacity of the drill. Gear
damage or motor overload may result (see "Specifications").
Side Handle
The side handle can be installed on either side of the tool. To install the
side handle, thread it into the socket on the desired side of the tool and
tighten it securely.

This tool is equipped with an adjustable switch handle that allows the
user to adjust the handle to three positions (90° apart) for optimum
operating position.
1. Unplug the tool.
2. Press in and hold the handle rotation release button and rotate the
switch handle to one of the three handle positions.
3. Release the handle rotation release button. The adjustable handle
has detents which allow the handle to snap into position. Make sure
the handle snaps firmly into position and does not rotate.
The tool will not operate if the handle is not locked securely in one of the
three positions.
