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.
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 15 clutch settings. Output
torque will increase as the clutch ring, is
rotated from 1 to 15. The drill “ ” position

IMPORTANT CHARGING NOTES
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.

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
l
ight 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.
CHARGING BATTERY PACK (BC830 1 HOUR CHARGER)
Plug charger cord into your standard power
outlet, then insert battery pack into charger
(Fig. 7).
The charger’s green indicator light will begin to
“BLINK”. This indicates that the battery is
receiving a fast charge. Fast-charging will
automatically stop when the battery pack is
fully charged.
When the unit beeps and the indicator light
stops “BLINKING” (and becomes a steady
green light) fast charging is complete.
The battery pack may be used even though
the light may still be blinking. The light may
require more time to stop blinking depending
on temperature. When you begin the charging
process of the battery pack, a steady red light

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.
could also mean the battery pack is too hot or
too cold.
The purpose of the green 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 needed, the internal fan of the charger
will turn on to aid the charging process and
speed.
When charging several batteries in sequence,
the charge time may slightly increase.
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.

Operating Tips
The purpose of the tether hook is to secure
the tool when working on ladders,
s
caffolding, or elevated heights to prevent
the tool from hitting the ground if accidentally
dropped. For best results, it is
recommended to use 1/4" braided nylon rope
or similar material.
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.

The trigger controlled variable speed feature
will eliminate the need for center punches in
h
ard materials. The variable speed trigger
allows you to slowly increase RPM. By using
a slow starting speed, you are able to keep
the bit from “wandering”. You can increase
the speed as the bit “bites” into the work by
squeezing the trigger.
Variable speed drills will double as a power
screwdriver by using a screwdriver bit in the
drill mode. 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.
DRILLING WITH VARIABLE SPEED
DRIVING WITH VARIABLE SPEED
FASTENING WITH SCREWS
This procedure shown in (Fig. 8) will enable
you to fasten materials together with your
Cordless Drill/Screwdriver without stripping,
splitting or separating the material.
First, clamp the pieces together and drill the
first hole 2/3 the diameter of the screw. If the
material is soft, drill only 2/3 the proper
length. If it is hard, drill the entire length.
Second, unclamp the pieces and drill the
second hole the same diameter as the screw
shank in the first or top piece of wood.
Third, if flat head screw is used, countersink
the hole to make the screw flush with the
surface. Then, simply apply even pressure
when driving the screw. The screw shank
clearance hole in the first piece allows the
screw head to pull the pieces tightly together.
The adjustable screw drill accessory will do
all of these operations quickly and easily.
DRILL BITS
Always inspect drill bits for excessive wear. Use
only bits that are sharp and in good condition.
TWIST BITS: Available with straight and
reduced shanks for wood and light duty metal
drilling. High speed bits cut faster and last
longer on hard materials.
CARBIDE TIPPED BITS: Used for drilling
stone, concrete, plaster, cement and other

DRILLING WOOD
Be certain workpiece is clamped or anchored
firmly. Always apply pressure in a straight line
with the drill bit. Maintain enough pressure to
keep the drill “biting”.

When drilling holes in wood, twist bits can be
used. Twist bits may overheat unless pulled out
frequently to clear chips from flutes.
Use a “back-up” block of wood for work that is
likely to splinter, such as thin materials.
You will drill a cleaner hole if you ease up on
the pressure just before the bit breaks through
the wood. Then complete the hole from the
back side.
There are two rules for drilling hard materials.
First, the harder the material, the greater the
pressure you need to apply to the tool. Second,
the harder the material, the slower the speed.
WARNING
!
safe operating speed is not exceeded by the
nameplate speed of the tool. Do not exceed
the recommended wheel diameter.
Fine sanding and polishing require “touch”.
Select the most efficient speed.
When using polishing bonnets, always be sure
the excess string that secures the bonnet is
tucked well within the bonnet during operation.
Work with brushes requires high speeds.
1. Remember, the tips of a wire brush do the
work. Operate the brush with the lightest
pressure so only the tips of the wire come in
contact with the work.
2. If heavier pressures are used, the wires
will be overstressed, resulting in a wiping
action; and if this is continued, the life of the
brush will be shortened due to wire fatigue.
3. Apply the brush to the work in such a way
that as much of the brush face as possible is
in full contact with the work. Applying the
side or edge of the brush to the work will

Here are a couple of tips for drilling in metal.
Lubricate the tip of the bit occasionally with
cutting oil except when drilling soft metals such
as aluminum, copper or cast iron. If the hole to
be drilled is fairly large, drill a smaller hole first,
then enlarge to the required size, it’s often
faster in the long run. Maintain enough
p
ressure to assure that the bit does not just
spin in the hole. This will dull the bit and greatly
shorten its life.
Soft materials such as brick are relatively easy
to drill. Concrete however, will require much
more pressure to keep the bit from spinning. Be
sure to use carbide tip bits for all masonry work.
result in wire breakage and shortened brush
life.
INCORRECT: Excessive pressure can cause wire breakage.
Variable speed control must be used with
caution for driving nuts and bolts with socket
set attachments. The technique is to start
slowly, increasing speed as the nut or bolt runs
down. Set the nut or bolt snugly by slowing the
drill to a stop. If this procedure is not followed,
the tool will have a tendency to torque or twist
in your hands when the nut or bolt seats.
