previously. DO NOT CONTINUE to
use the drill with its battery in a
depleted condition.
6. To prolong battery life, avoid leaving
the tool on charge for more than 5
hours. Although overcharging is not
a safety concern, it can significantly
reduce overall battery life.
7. A fully charged product, after being
off charge for 1 month, will still have
75% of its energy in the battery
pack; after 6 months, 50% will
remain.
8. Since the unit is designed for
cordless applications, use of the unit
while plugged in is of no benefit. ■
Batteries will still become depleted.
9. Unplug your tool’s charger from the
power supply before disconnecting
the charger from the tool. Under
certain conditions, with the charger
plugged in to the power supply, the
exposed charging plug can be
shorted by foreign material and may
cause a fire. Foreign materials of
conductive nature, such as but not
limited to, steel wool, aluminum foil,
or any build up of metallic particles
should be kept away from the
charging plug. Unplug charger
before attempting to clean.
10. Longest life and best performance
can be obtained if the batteries are
charged when the air temperature is
about +75°F. DO NOT charge the
batteries in an air temperature below
+40°F or above 105°F. This is im­
portant and may prevent serious
damage to the batteries.
Operation
FOR LONGEST PRODUCT LIFE, DON’T
FORCE TOOL!
DRILLING
1. 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. For MASONRY, such as
brick, cement, cinder block, etc., use
carbide tipped bits.
2. 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.
3. 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". See
Figure 8.
4. Always apply pressure in a straight
line with the bit. Use enough pres­
sure 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 the last part of hole.
5. Field Drill firmly to control its twisting
action.
DRILLING IN WOOD
Floles in wood can be made with the
same twist drill bits used for metal. These
bits should be sharp and should be pulled
out frequently when drilling to clear chips
from the flutes. Work that is apt to splinter
should be backed up with a block of wood.
Let up on the pressure just before the tip
cuts through, this will give a good clean
hole.
DRILLING IN METAL
Use a cutting lubricant when drilling
ferrous metals. The exceptions are 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.
