Depress and release switch trigger to besure your,
drill is in OFF position before connecting itto
power supply.
Check the direction of rotation lever for correct
setting (forward or reverse). See Figure 4.
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 drillfirmly and place bit at 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 intothe workpiece applying only
enough pressure to keep the bit cuffing. Do not
force your drill or apply side pressure to elongate
a hole. Let your ddll and bit do the work. See
Figures 8 and 9.
_k ARNING: 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 materials. If not
prepared, this loss of controlcan result in
possible serious injury.
When drilling hard, smooth surfaces use a center
punch to mark the desired hole location. This will
prevent the ddll bit from slipping off center as the hole
is started. However, the variable speed feature allows
starting holes without center punching ifdesired. To
accomplish this, operate your drill at a low speed until
the hole is started.
When drilling metals use a light oil on the drillbit to
keep itfrom overheating. The oil will prolong the life of
the bit and increase the drillingaction.
If the bit jams in the work piece or ifyour drillstalls,
stop the tool immediately. Remove the bit from the
work piece and determine the reason for jamming.
LEVEL DRILLING
See Figures 8 and 9.
A convenient feature provided with your drill is a level.
It is recessed in the motor housing on your ddll. It can
be used to keep drillbits level during both horizontal
and vertical drilling operations.
