1. The charger was designed to fast charge
the battery only when the battery
temperature is between 32˚F (0˚C) and
140˚F (60˚C). If the battery pack is too hot or
too cold, the charger will not fast charge the
battery. (This may happen if the battery pack
is hot from heavy use). When the battery
temperature returns to between 32˚F (0˚C)
and 140˚F (60˚C), the charger will
automatically begin charging.
2. A substantial drop in operating time per
charge may mean that the battery pack is
nearing the end of its life and should be
replaced.
3. Remember to unplug charger during
storage period.
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.
Use carbide-tipped SDS-plus
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.
Maintenance
Disconnect tool and/or charger from power
source before servicing.
Be alert for battery packs that are nearing
their end of life. If you notice decreased
tool performance or significantly shorter
running time between charges then it is time
to replace the battery pack. Failure to do so
can cause the tool to operate improperly or
damage the charger.
