Bosch 23612 - Manual (Page 10)

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 40˚F (4˚C) and
105˚F (41˚C).
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 will void the warranty.
When the indicator light stops “BLINKING”
(and becomes a steady green light) fast
charging is complete.
When you begin the charging process of the
battery pack, a steady green light could also
mean the battery pack is too hot or too cold.
The purpose of the light is to indicate that the
battery pack is fast-charging. It does not
indicate the exact point of full charge. The
light will stop blinking in less time if the
battery pack was not completely discharged.
When the battery pack is fully charged,
unplug the charger (unless you're charging
another battery pack) and slip the battery
pack back into the tool handle.
To prevent fire or injury when batteries are
not in tool or charger, always place protective
cap onto end of battery pack.
Operating Tips

IMPORTANT CHARGING NOTES
You will extend the life of your bits and do
neater work if you always put the bit in
contact with the work before pulling the
trigger. During the operation, hold the tool
firmly and exert light, steady pressure. Too
much pressure at low speed will stall the tool.
Too little pressure will keep the bit from
cutting and cause excess friction by sliding
over the surface. This can be damaging to
both tool and bit.
DRIVING WITH VARIABLE SPEED
The technique is to start slowly, increasing
the speed as the screw runs down. Set the
screw snugly by slowing to a stop. Prior to
driving screws, pilot and clearance holes
should be drilled.
Always hold the machine straight on the bolt
to be tightened.
The best method to determine the right
impacting/tightening duration is by means of
a trial. For small screws, the right
impacting/tightening duration can be reached
in less then 0.5 Sec. Therefore, work with
low RPM and switch the machine off
immediately when the screw is tight and the
impacting sound can be heard.
