3. OPERATION'
SWITCH
To Start Drill, depress trigger switch; to stop Drill, release trigger. To
lock trigger in “ON" position for continuous operation, depress trigger
and push up locking button (located below the trigger), then gently
release trigger. To release locking mechanism, depress trigger fully, then
release It. Before using the tool (each time) be sure that the lock button
release mechanism is working freely.
Do not lock the switch “ON" when drilling by hand so that you can
instantly release the trigger switch if the bit binds in the hole.
Be sure to release the switch locking button before disconnecting the
plug from the power supply. Failure to do so will cause the tool to start
immediately the next time it is plugged in. Damage or injury could result.
The Variable Speed Trigger Switch (Nos. 7014 & 7114 Drills only) permits
speed control — the farther the trigger is depressed, the higher the speed
of the Drill.
NOTE: Use lower speeds for starting holes without a center
punch, drilling in metal or plastics, driving screws, drilling ceramics, or
mixing paint. Higher speeds are better for drilling wood and composition
boards, and for using abrasive and polishing accessories.

DRILLING
1. 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 high-speed steel
twist drill bits or hole saws. For MASONRY, such as brick, cement,
cinder block, etc., use carbide-tipped bits.
3. Be sure the material to be drilled is anchored or clamped firmly,
if drilling thin material, use a wood “back-up" block to prevent
damage to material.
4. Center-punch an indentation at the point to be drilled. This will
overcome tendency of bit to slip around on a smooth surface. Place
the tip of bit in indentation and turn motor “ON."
NOTE: With the
Variable Speed Drills, holes can be started at low speed without the
need for center punching.
5. 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
motor or deflect bit. To minimize stalling on breaking through the
material, reduce pressure on drill and ease the bit through last part
of hole.
6. Hold drill firmly to control the twisting action of the drill.
7.
THE DRILL STALLS if it is being overloaded or improperly used.
RELEASE TRIGGER IMMEDIATELY, remove drill bit from work, and
determine cause of stalling. DO NOT CLICK TRIGGER OFF AND ON
IN ATTEMPT TO START A STALLED DRILL
8. Keep motor running when pulling bit back out of a drilled hole.
This will help prevent jamming.
