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 counter-
clockwise 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.
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 pres-
sure 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

7. To minimize stalling on breaking through the material, reduce pressure
8. Keep the motor running when pulling the bit back out of a drilled hole.
9. With variable speed drills there is no need to center punch the point to

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
sulphurized cutting oil or lard oil; bacon grease will also serve the purpose.
Drilling in Masonry
Use carbide tipped masonry bits at low speeds. Keep even force on the drill
but not so much that you crack the brittle materials. A smooth, even flow of
dust indicates the proper drilling rate.

be drilled. Use a slow speed to start the hole and accelerate by squeez-
ing the trigger harder when the hole is deep enough to drill without the
bit skipping out. Operate at full speed after starting the bit.
