,_,
WARNING:
Failure to unplug your drill could
result in accidental starting causing serious
injury.
•
On models 315.101211 and 315.101221 loosen the
chuck jaws using only the chuck key provided.
•
On model 315.101231 loosen chuck jaws by
grasping and holding the collar of the chuck with
one hand and rotating the chuck body in the
direction of the arrow marked UNLOCK with your
other hand.
•
Do notuse a wrench to tighten or loosen the chuck
jaws.
•
Remove drill bit from chuck jaws.
•
On models 315.101211 and 315.101221 remove
chuck key and return to storage area.
DRILLING
See Figure 9.
•
Depress and release the switch trigger to be sure
your drill is in Off position before connecting it to
power supply.
•
Check the direction of rotation lever for correct
setting (forward or reverse). See Figure 3.
•
Secure the 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 your drill may
need to be stopped suddenly.
•
Move the drill bit into 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.
When drilling, hard smooth surfaces use a center
punch to mark desired hole location. This will prevent
the drill bit from slipping off center as the hole is
started. However, the variable speed feature on
models 315.101221
and 315.101231 allows starting
holes without center punching if desired. To accom-
plish this, simply operate your drill at a low speed until
the hole is started.

WARNING:
Be prepared for binding or bit
breakthrough.
When these situations occur, drill
has a tendency to grab and kick opposite to the
direction of rotation and could cause loss of
control when breaking through material. If not
prepared, this toss of control can result in
possible serious injury.
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 workpiece or if the drill stalls, stop the
tool immediately. Remove the bit from the workpiece
and determine the reason for jamming.
