Operation - Milwaukee 1680-20 Operator's Manual

To reduce the risk of injury, wear safety goggles
or glasses with side shields.
To reduce the risk of personal injury when drill-
ing, hold tool by insulated gripping surfaces when
performing an operation where the cutting tool
may contact hidden wiring or its own cord. Con-
tact with a "live" wire will make exposed metal
parts of the tool "live" and shock the operator.
To reduce the risk of injury, hold or brace se-
curely. Always be prepared for bit binding and
drill reaction.
Clutch
The Super Hawg ™ has a clutch that is active when the tool is running in
low speed only. The clutch disengages the bit from the geartrain to
protect the tool. When a high load is encountered, the clutch will slip and
a ratcheting sound will be heard. Release the trigger switch when the
clutch begins to slip (see "Bit Binding"). Continuous use of the tool when
the clutch is slipping will reduce the life of the mechanism.
Bit binding (Fig. 5)
Fig. 5
If the bit binds, the drill will suddenly react in the opposite direction of the
rotation of the bit. Figure 5 shows the path of reaction, (B) if the drill bit
binds while being driven in forward (A). Reduce the chances of a sud-
den reaction by following the instructions listed below. Prepare for a
sudden reaction by holding or bracing securely.
To reduce the chance of bit binding:
• 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.
• Use the proper speed for the size bit. Larger bits should be run at
the lower speed (see "Specifications"). Driving larger bits at high
speeds will increase the chance of the bit binding and increase the
chance of reaction.
• Keep selfeed bits aligned with the work surface so bits go in straight
(see "Drilling").
• Avoid drilling warped, wet, knotty, and/or pitchy material if possible.

OPERATION

• Avoid drilling in material that you suspect contains hidden nails or
other things that may cause the bit to bind.
The direction of reaction is always opposite of the direction of bit rota-
tion. Reaction is even more likely to occur when enlarging already exist-
ing holes and at the point when the bit breaks through the other side of
the material.
If the bit does bind:
1. Release the trigger immediately.
2. Reverse the motor.
3. Remove the bit from the work and start again.
4. Do not pull the trigger on and off to attempt to start a stalled bit. This
will damage the drill.
Bracing for forward rotation (Fig. 6 & 7)

A
When drilling in forward, the bit will rotate in a clockwise direction. If the
bit binds in the hole, the bit will come to a sudden stop and drill will
suddenly react in a counterclockwise direction.
There are two ways to properly brace the Super Hawg
rotation (Fig. 6 & 7).
A. Forward (clockwise) rotation
B. Reaction
C. Brace drill with side handle here
D. Brace drill with gearcase here
If the bit binds, the side handle or the gearcase braced against the stud
will hold the drill in position.
