Operation
CAUTION: Always unplug the tool when attaching or changing
bits or accessories.
1. Open the chuck jaws by turning collar with fingers and
insert bit fully into the chuck. Tighten chuck collar by hand.
Place chuck key in each of the three holes, and tighten in
clockwise direction. It’s important to tighten chuck with all
three holes to prevent slippage. To release bit, turn chuck
key counter clockwise in just one hole, then loosen chuck
by hand.
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 the material.
4. 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.
5. Hold drill firmly to control the twisting action of the drill.
Use side handle.
CAUTION: 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.
6. 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 OFF AND
ON IN AN ATTEMPT TO START A STALLED DRILL—
THIS CAN DAMAGE THE DRILL.
7. To minimize stalling on breaking through the material,
reduce pressure on drill and ease the bit through the last
fractional part of the hole.
8. Keep the motor running when pulling the bit back out of a
drilled hole. This will help prevent jamming.
DRILLING IN METAL
Use a cutting lubricant when drilling metals. The exceptions are
cast iron and brass which should be drilled dry. The cutting
lubricants that work best are sulphurized cutting oil or lard oil;
bacon grease will also serve the purpose.
DRILLING IN WOOD
Holes in wood can be made with the same twist drills used for metal.
These bits may overheat unless pulled out frequently to clear chips
from the flutes. For larger holes, use Power Drill Wood Bits. Work
that is apt to splinter should be backed up with a block of wood.
Chuck
1. Always completely insert the shank of the drill bit or
accessory in the chuck. This permits full gripping power
and prevents cocking the chuck jaws. When using drill bits
or accessories with 3 “flats” on the shank, the chuck jaws
should be located on the center of these flats.
2. Use all three holes in the chuck body to tighten the jaws. Insert
the chuck key into each hole and tighten as much as possible.
To release the drill bit, use the chuck key in only one hole.
3. Use only a chuck key to tighten or loosen the chuck jaws.
