restored in two or three charge/discharge
cycles. Remember to unplug charger during
storage period.
5. If battery does not charge properly:
a. Check for voltage at outlet by
plugging in some other electrical device.
b. Check to see if outlet is connected to
a light switch which turns power “off” when
lights are turned off.
c. Check battery pack terminals for dirt.
Clean with cotton swab and alcohol if
necessary.
d. If you still do not get proper charging,
take or send tool, battery pack and charger
to your local Skil Service Center. See “Tools,
Electric” in the Yellow Pages for names and
addresses.
Note:
Use of chargers or battery packs not
sold by Skil may void the warranty.
DRILLING WOOD OR PLASTIC
If backing block is not used, ease up on the
pressure just before the bit breaks through
the wood to avoid splintering. Complete the
hole from the opposite side immediately
after the point breaks through. If bit binds,
reverse the drilling operation to help remove
the bit from the work.
DRILLING METAL
Make a center punch in the material for
easier starting. Use enough pressure to keep
the bit cutting. If the bit is allowed to merely
spin in the hole, it will become dull within a
short time. When drilling a larger hole, it is
faster and easier on your power pack to first
make a smaller hole and enlarge it to the
required size. Lubricate the tip of the bit
occasionally with CUTTING OIL for easier
metal drilling. If bit binds, reverse the drilling
to help remove the bit from the work.
It is not recommended to drill holes larger
than 3/8" diameter through soft steel thicker
than 1/8". Drilling through metal rapidly
drains energy from your power pack.
DRILLING MASONRY
Use carbide-tipped masonry bit for cinder
block, mortar, common brick, soft stone and
other materials. The amount of pressure to
be used is dependent upon the type of
material being drilled. Soft materials require
less pressure while the hard materials need
more pressure to prevent the drill bit from
spinning.
FASTENING WITH SCREWS
This procedure shown in (Fig. 6) will enable
you to fasten materials together with your
Cordless Drill/Screwdriver without stripping,
splitting or separating the material.
First, clamp the pieces together and drill the
first hole 2/3 the diameter of the screw. If the
material is soft, drill only 2/3 the proper
length. If it is hard, drill the entire length.
Second, unclamp the pieces and drill the
second hole the same diameter as the screw
shank in the first or top piece of wood.
Third, if flat head screw is used, countersink
the hole to make the screw flush with the
surface. Then, simply apply even pressure
when driving the screw. The screw shank
clearance hole in the first piece allows the
screw head to pull the pieces tightly
together.
The adjustable screw drill accessory will do
all of these operations quickly and easily.
Screw drills are available for screw sizes No.
6, 8, 10 and 12.

meter as
