Let the tool do the work.
Warning! Be prepared for binding at bit breakthrough. When these situations
occur, drill has a tendency to grab and kick opposite to the direction of rotation
to grab and kick opposite 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.
TIP FOR DRILLING HARD SMOOTH SURFACES
Place a piece of masking tape onto the surface in the approximate position for
the hole. Mark the position of the hole onto the masking tape this will prevent
the drill from skidding across the surface when the drill is started. Slowly drill
through the surface.
TIP FOR DRILLING METAL
When drilling metal, 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.
TIP FOR MOSONRY DRILLING
For maximum performance, use carbide-tipped masonry impact bit when
drilling holes in brick, tile, concrete, etc.
For maximum performance, use high speed steel bits.
Apply light pressure and medium speed for best results in brick.
Apply additional pressure for hard materials such as concrete.
WORKPIECE CLAMPING
To prevent the drill bit from spinning the work piece if the drill bit becomes
jammed in the hole being drilled, it is recommended that a drill vice or other
suitable clamp is used to secure the work piece during the drilling operation.
If the bit jams in the workpiece or if the drill stalls, stop the tool immediately.
Remove the bit from the workpiece and determine the reason for jamming.
Note: This drill has an electric brake. When the switch trigger is released, the
chuck stops turning. When the brake is functioning properly, sparks will be
visible through the vent slots on the housing. This is normal and is the action
of the brake.
