Trigger Switch (Fig. 1)
To start the drill, depress the trigger switch; to stop the drill, release
the trigger switch.
NOTE: Use lower speeds for starting holes without a center punch,
drilling in metal or plastics, driving screws or drilling ceramics.
Higher speeds are better for drilling wood and composition boards
and using abrasive and polishing accessories.
VARIABLE SPEED
A variable speed trigger switch (A) permits speed control—the
farther the trigger is depressed, the higher the speed of the drill.
For continuous operation, press and hold the variable speed switch,
move the lock-on button (B) up, then release the switch.
To stop continuous operation, press the switch briefly and release
it. Always switch the tool off when work is finished and before
unplugging.

(Fig. 9)
WARNING: To reduce the risk of serious
personal injury, ALWAYS use proper hand
position as shown in figure 9.
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 main handle (J), with the other hand on
the side handle (G).
Drilling
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. 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.
2. 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.
3. Hold tool firmly with both hands to control the twisting action of
the drill.
4. 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.
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.
DRILLING IN METAL
Start drilling with slow speed and increase to full power while
applying firm pressure on the tool. A smooth even flow of metal
chips indicates the proper drilling rate. Use a cutting lubricant when
drilling metals. The exceptions are cast iron and brass which should
be drilled dry.
NOTE:
Large [5/16" (8 mm) to 1/2" (13 mm)] holes in steel can be
made easier if a pilot hole [5/32" (4 mm) to 3/16" (5 mm)] is drilled
first.
