Drill Operation


WARNING: To reduce the risk of serious personal injury,
turn tool off and disconnect tool from power source
before making any adjustments or removing/installing
attachments or accessories.

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.
1. Install and tighten the desired drill bit in the chuck.
Select the desired speed/torque range using the dual
range gear shifter to match the speed and torque to the
planned operation.
2. Use sharp drill bits only.
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 with both hands to control the twisting
action of the drill. If model is not equipped with side handle,
grip drill with one hand on the handle and one hand on the
battery pack.

WARNING: Drill may stall if overloaded causing a sudden
twist. Always expect the stall. Grip the drill firmly to control
the twisting action and avoid injury.
5. iF DRill sTAlls, it is usually because it is being
overloaded or improperly used. RElEAsE paddle switch

6. To minimize stalling or breaking through the material,
reduce pressure 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 accelerate by squeezing the paddle switch harder when
the hole is deep enough to drill without the bit skipping out.
