WARNING: To reduce the risk of serious personal injury,
turn tool off and disconnect tool from power source before

WARNING: To reduce the risk of personal injury, ALWAYS
ensure workpiece is anchored or clamped firmly. If drilling thin
material, use a wood "back-up" block to prevent damage to the
material.

DRILLING OPERATION
1. For WOOD, use twist bits, spade bits, power auger bits or hole
saws. For METAL, use high-speed steel twist drill bits or hole
saws. Use a cutting lubricant when drilling metals. The exceptions
are cast iron and brass which should be drilled dry. For
MASONRY, use carbide-tipped bits or masonry bits. A smooth,
even flow of dust indicates the proper drilling rate.
2. Always apply pressure in a straight line with the bit. Use enough
pressure to keep the drill bit biting, but do not push hard enough
to stall the motor or deflect the bit.
3. Hold tool firmly with both hands to control the twisting action of
the drill.
WARNING: Drill may stall if overloaded causing a sudden twist.
Always expect the stall. Grip the drill firmly with both hands to control
the twisting action and avoid injury.
4. IF DRILL STALLS, it is usually because it is being overloaded.
RELEASE TRIGGER IMMEDIATELY, remove drill bit from
work, and determine cause of stalling. DO NOT CLICK
TRIGGER OFF AND ON IN AN ATTEMPT TO START A
STALLED DRILL – THIS CAN DAMAGE THE DRILL.
