OPERATION
TO INSTALL BITS
See Figure 7.
1. UNPLUG YOUR DRILL.
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.
3. Insert drill bit into chuck the full length of the jaws.
4, Tighten chuck jaws securely, using only the chuck key
provided. DO NOT USE A WRENCH TO TIGHTEN OR
LOOSEN THE CHUCK JAWS.
5, Remove chuck key and return to storage area.
DRILLING
See Figure 9.
1, Depress and release switch trigger to be sure your drill
is in "Off" position before connecting it to power
supply.
2. Check the direction of rotation lever for correct setting
(forward or reverse). See Figure 3.
3, Secure the material to be drilled in a vise or with clamps
to keep it from turning as the drill bit rotates.
4. Plug your drill into power supply source.
5. Hold your drill firmly and place bit at point to be drilled.
6. Depress the switch trigger to start your drill. Do not lock
the switch "On" for jobs where your drill may need to
be stopped suddenly.

enough pressure to keep the bit cutting. Do not force
your drill or apply side pressure to elongate a hole. Let
your drill and bit do the work. See Figure 9.
