Unplug your drill.
_ WARNING: Failure to unplug your drill could
result in accidental starting causing serious injury.

Remove chuck key.
POWER CORD
See Figure 8.
Your new electronic drill has a 10 foot power cord that
stays soft and flexible in cold weather. The plug design
is shaped so that it won't snag on your work during use.
A molded cord clip on the plug makes cord storage
easier.

DRILLING
See Figure 9.
Depress and release the switch trigger to be sure
your drill is in the "Off" position before connecting it
to power supply.
Check the direction of rotation lever for correct
setting (forward or reverse).
Secure thye material to be drilled in a vise or with
clamps to keep it from turning as the drill bit rotates.
Plug your drill into power supply source.
Hold your drill firmly and place the bit at the point to
be drilled.
Depress the switch trigger to start your drill. Do not
lock the switch "On" for jobs where the drill may
need to be stopped suddenly.
Move the drill bit intothe workpiece applying only
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.
_ll WARNING: Be prepared for binding or bit
breakthrough. When these situations occur, drill
has a tendency to grab and kickopposite to the
direction of rotation and could cause loss of
control when breaking through material. If not
prepared, this loss of control can result in possible
serious injury.
When drilling hard smooth surfaces use a center punch
to mark the desired hole location. This will prevent the
drill bit from slipping off center as the hole is started.
However, the variable speed feature allows starting
holes without center punching if desired. To accomplish
this, simply operate your drill at a low speed until the
hole is started.
When drilling metals use a light oil on the drill bit to
keep it from overheating. The oil will prolong the life of
the bit and increase the drilling action.
If the bit jams in the workpiece or if your drill stalls, stop
the tool immediately. Remove the bit from the
workpiece and determine the reason for jamming.
