Operation
DRILLING
1. Always unplug the drill when attaching or changing bits or
accessories.
2. Use sharp drill bits only. For WOOD, use twist drill bits, spade bits,
power auger bits, or hole saws. For METAL, use steel twist drill
bits or hole saws. For MASONRY, such as brick, cement, cinder
block, etc., use carbide-tipped bits rated for percussion drilling. Be
sure the material to be drilled is anchored or clamped firmly. If
drilling thin material, use a wood “back-up” block to prevent dam-
age to the material.
3. Always apply pressure in a straight line with the bit. Use enough
pressure to keep drill biting, but do not push hard enough to stall
the motor or deflect the bit.
4. Hold tool firmly to control the twisting action of the drill.
5. IF DRILL STALLS, it is usually because it is being overloaded or
improperly used. RELEASE TRIGGER IMMEDIATELY, remove
drill bit from work, and determine cause of stalling. DO NOT
CLICK TRIGGER ON AND OFF IN AN ATTEMPT TO START A
STALLED DRILL — THIS CAN DAMAGE THE DRILL.
6. To minimize stalling or breaking through the material, reduce pres-
sure on drill and ease the bit through the last fractional part of the
hole.
7. Keep the motor running when pulling the bit back out of a drilled
hole. This will help prevent jamming.
8. With variable speed drills there is no need to center punch the
point to be drilled. Use a slow speed to start the hole and accel-
erate by squeezing the trigger harder when the hole is deep
enough to drill without the bit skipping out.
