GEAR SHIFTING
Your tool is equipped with two separate gear
ranges, low gear and high gear. Low gear
provides high-torque and slower drilling
speeds for heavy duty work or for driving
screws. High gear provides faster speeds for
drilling lighter work. To change speeds slide
switch, to the high or low position (Fig. 1).
ATTENTION: If your tool appears to be
running, but the chuck will not turn, check to
make sure the gear shifting switch is pushed
fully into desired setting.
ADJUSTABLE CLUTCH
Your tool features 20 clutch settings. Output
torque will increase as the clutch ring, is
rotated from 1 to 19. The drill "
will lock up the clutch to permit drilling and
driving heavyduty work (Fig. 1).
INSERTING AND RELEASING
BATTERY PACK
Release battery pack from tool by pressing on
both sides of the battery release tabs and pull
downward (Fig. 4).
To insert battery, align battery and slide
battery pack into tool until it locks into position.
Do not force.
If battery release tabs are
WARNING
cracked
damaged, do not insert into tool. Battery can
fall out during operation.
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.
When the trigger switch is released it
activates the brake to stop the chuck quickly.
This is especially useful in the repetitive
driving and removal of screws.
Your tool is equipped with an automatic locking
system. This feature will lock the bit holder in
one position when the trigger switch is
released. This will allow you to tighten or loosen
a nut or screw by rotating the tool by hand with
the switch off. This is convenient when higher
turning torque is needed.
Your tool is also equipped with a light that turns
" position
on automatically when the switch is activated,
for better visibility when drilling/driving (Fig. 1).
or otherwise
IMPORTANT CHARGING NOTES
4. 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.
