OPERATION

WARNING:

Your drill should never be connected to power supply
when you are assembling parts, making adjustments,
installing or removing drill bits, or when not in use.
Disconnecting your drill will prevent accidental starting
that could cause serious injury.

TO INSTALL BITS

1. UNPLUG YOUR DRILL.

WARNING:

Failure to unplug your drill could result in accidental
starting causing serious injury.

2. Open or close the chuck jaws to a point where the

opening is slightly larger than the drill bit you intend to
use. Also, raise the front of your drill slightly to keep the
drill bits from falling out of the chuck jaws.

the chuck key provided. Do not use a wrench to
tighten or loosen the chuck jaws.
