WARNING: To reduce the risk of personal injury, ALWAYS
operate the tool with the side handle properly installed and
securely tightened. Failure to do so may result in the side handle
slipping during tool operation and subsequent loss of control. Hold
tool with both hands to maximize control.
Proper Hand Position (Fig. 1, 5)
WARNING: To reduce the risk of serious personal injury, ALWAYS
use proper hand position as shown.
WARNING: To reduce the risk of serious personal injury, ALWAYS
hold securely in anticipation of a sudden reaction.
Proper hand position requires one hand on the side handle (H), with
the other hand on the main handle (B).

drill bit symbol for drilling, to the hammer symbol for hammering or to
the hammerdrill symbol for hammerdrilling.
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.
5. To minimize stalling or breaking through the material, reduce
pressure on drill and ease the bit through the last fractional part
of the hole.
6. Keep the motor running when pulling the bit back out of a drilled
hole. This will help prevent jamming.
7. 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 trigger harder when the hole is deep
enough to drill without the bit skipping out.
