Bosch 11524 - Manual (Page 11)

1. The battery pack accepts only about 80%
of its maximum capacity with its first few
charge cycles. However, after the first few
charge cycles, the battery will charge to full
capacity.
2. 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.
3. 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.
4. If you anticipate long periods (i.e. a month
or more) of non-use of your tool, it is best to
run your tool down until it is fully discharged
before storing your battery pack. After a long
period of storage, the capacity at first
recharge will be lower. Normal capacity will
be 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 Bosch Service Center. See
“Tools, Electric” in the Yellow Pages for
names and addresses.
Note: Use of chargers or battery packs not
sold by Bosch may void the warranty.
IMPORTANT CHARGING NOTES
If the indicator lights are “OFF”, the
charger is not receiving power from
power supply outlet.
If the green indicator light is “ON”,
the charger is plugged in but the
battery pack is not inserted, or the
battery pack is fully charged and is
being trickle charged.
If the green indicator light is
“BLINKING”, the battery pack is
being fast-charged. Fast-charging
will automatically stop when the
battery pack is fully charged.
If the red indicator light is “ON”,
the battery pack is too hot or cold
for fast-charging. The charger will
switch to trickle charge, until a
suitable temperature is reached, at which
time the charger will switch automatically to
fast-charging.
If the red indicator light is
“BLINKING”, an acoustical signal
will sound for a period of 2 seconds
which indicates the battery pack
cannot accept a charge or the contacts of
the charger or battery pack are
contaminated. Clean the contacts of the
charger or battery pack only as directed in
these operating instructions or those
supplied with your tool or battery pack.

INDICATORS, SYMBOLS AND MEANING
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
