Depressand release the switch tdgger to be sure
your ddll is in off position before connectingit to
power supply.
• Check the directionof rotationlever for correct
setting(forward or reverse). See Figure 3.
•
Secure the materialto be drilled in a vise or with
clamps to keep it from turningas the drillbit 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 switchon for jobs where your drillmay
need to be stopped suddenly.
•
Move the drillbit intoworkpiece applyingonly
enough pressure to keep the bit cutting.Do not
force your drillor apply side pressure to elongate a
hole. Let your drilland bit do the work.
When drilling hard, smooth surfaces use a center
punch to mark desired hole location.This will prevent
the drill bitfrom slippingoff center as the hole is
started.

WARNING:
Be prepared for bindingor bit
breakthrough.When these situationsoccur, ddll
has a tendency to grab and kick oppositeto the
directionof rotationand could cause loss of
controlwhen breaking through material If not
prepared, this loss of controlcan result in
possibleserious injury.
When drillingmetals, use a light oil on the drillbit to
keep it from overheating.The oil will prolongthe life of
the bit and increase the drillingaction.
If the bit jams in workpiece or if the drillstalls, stop the
tool immediately. Remove the bit from the workpiece
and determine the reason for jamming.
