OPERATION
NOTE:
This drill has an electric brake. When the switch trig-
ger is released, the chuck stops turning.
NOTE:
If an operation creates considerable dust resulting
in low visibility of the workpiece, frequent vacuuming of the
work area is recommended.
WOOD AND METAL DRILLING
For maximum performance, use high speed steel bits for
wood or metal drilling. Select drilling mode. Begin drilling
at a very low speed to prevent the bit from slipping off the
starting point.
Wood Drilling
Increase the speed as the drill bit bites into the material.
When drilling through holes, place a block of wood behind
the workpiece to prevent ragged or splintered edges on
the back side of the hole.
Metal and Steel Drilling
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.
Maintain a speed and pressure which allows cutting
without overheating the bit. Applying too much pressure
will:
• Overheat the drill;
• Wear the bearings;
• Bend or burn bits; and
• Produce off-center or irregular-shaped holes.
When drilling large holes in metal, start with a small bit,
then finish with a larger bit.
MASONRY DRILLING
For maximum performance, use carbide-tipped masonry
impact bits or designated hammer drill bits when drilling
holes in brick, tile, concrete, etc. Select hammer mode.
Apply light pressure at medium speed for best results in
brick.
Apply additional pressure for hard materials such as
concrete.
When drilling holes in tile, practice on a scrap piece to
determine the best speed and pressure. Begin drilling at
a very low speed to prevent the bit from slipping off the
starting point.
MAINTENANCE
WARNING:
When servicing, use only identical replacement
parts. Use of any other parts could create a hazard
or cause product damage.
GENERAL MAINTENANCE
Avoid using solvents when cleaning plastic parts. Most
