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 “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 the drill bit biting, but do not push hard enough to
stall the motor or deflect the bit.
5.Hold tool firmly to control the twisting action of the drill.
6.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 ON
AND OFF 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 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 spade bits, power auger bits, or
hole saws. Work that is likely to splinter should be backed up with a
block of wood.
Drilling in Metals
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 sulphurised cutting oil or lard oil; bacon grease will
also serve the purpose.

Chuck
To insert bit, open chuck jaws by turning collar with fingers and
insert shank of bit about 3/4" (19mm) into 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 release bit, turn chuck key counterclockwise in just one hole,
then loosen the chuck by hand.
Chuck Key Holder
May be installed already.
1. Push double hole end of holder through slot in other end of holder
as shown in Figure 3.
2. Slip loop over electric plug and draw loop tight around cord
(Figure 4).
3. Push ends of chuck key handle through two holes in end of holder
as shown in Figure 5.
Chuck Removal
1. TURN OFF TOOL AND DISCONNECT FROM POWER SUPPLY.
2. Place chuck key in chuck as shown in Figure 6.
3. Using a wooden mallet or similar object, strike key sharply in a
clockwise direction. This will loosen screw inside chuck (Figure 6).
4. Open chuck jaws fully. Insert screwdriver (or 3/16", 5mm, hex
wrench if required) into front of chuck between jaws to engage
screw head.
5. Remove screw by turning clockwise (left-hand thread).
6. Place key in chuck as shown in Figure 7.
7. Using a wooden mallet or similar object, strike key sharply in a
counterclockwise direction. This will loosen chuck so that it can be
unscrewed by hand (Figure 7).
Drilling
1.Always turn off tool and disconnect from power supply when
attaching or changing bits or accessories.
