1. The charger was designed to fast charge
the battery only when the battery temperature
is between 32˚F (0˚C) and 113˚F (45˚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 113˚F (45˚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.
4. If battery does not charge properly:
TOOL TIPS
Following a few simple tips will reduce wear
on the tool and the chance of injury to the
operator.
NOTE: The high efficiency available from the
rotary hammers can only be obtained if sharp
and undamaged accessories are used. The
"cost" to maintain sharp and undamaged
accessories is more than offset by the "time
saved" in operating the tool with sharp
accessories.
You will extend the life of your bits and do
neater work if you always put the bit in contact
with the workpiece BEFORE pulling the trigger.
During operation, hold the drill firmly and exert
moderate, steady pressure. Too much
pressure at low speed will stall the hammer.
Too little pressure will keep the bit from cutting
and cause excess friction by sliding over the
surface. This can be damaging to the drill and
bit.
Shanks of all drill bits should be wiped clean
prior to using and immediately after removing.
Recall these instructions for safe operation:
1. Some materials require slow drilling
speeds; whereas, others require higher speed
to produce the best results.
2. All work must be supported or secured
before drilling and steady, even pressure
applied in line with the drill bit.
3. As the drill bit cuts through the opposite
side, reduce the pressure and continue
running the drill as the bit is withdrawn.

IMPORTANT CHARGING NOTES
-14-
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 will void the warranty.
Materials such as glass, porcelain, ceramics,
tiles, plastics, etc., should be drilled at low
speeds with specially designed drill bits and
lubricants.
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.
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.
