Safety Notes

General Power Tool Safety Warnings

WARNING

the warnings and instructions may result in elec­tric shock, fire and/or serious injury.

Save all warnings and instructions for future
reference.

The term “power tool” in the warnings refers to
your mains-operated (corded) power tool or
battery-operated (cordless) power tool.

1) Work area safety

a) Keep work area clean and well lit. Clut-

tered or dark areas invite accidents.

b) Do not operate power tools in explosive

atmospheres, such as in the presence of
flammable liquids, gases or dust. Power

tools create sparks which may ignite the
dust or fumes.

c) Keep children and bystanders away

while operating a power tool. Distrac-

tions can cause you to lose control.

2) Electrical safety

a) Power tool plugs must match the outlet.

Never modify the plug in any way. Do not
use any adapter plugs with earthed
(grounded) power tools. Unmodified

plugs and matching outlets will reduce
risk of electric shock.

b) Avoid body contact with earthed or

grounded surfaces, such as pipes, radia­tors, ranges and refrigerators. There is

an increased risk of electric shock if your
body is earthed or grounded.

c) Do not expose power tools to rain or wet

conditions. Water entering a power tool

will increase the risk of electric shock.

d) Do not abuse the cord. Never use the

cord for carrying, pulling or unplugging
the power tool. Keep cord away from
heat, oil, sharp edges and moving parts.

Damaged or entangled cords increase the
risk of electric shock.

Read all safety warnings and all
instructions. Failure to follow

e) When operating a power tool outdoors,

use an extension cord suitable for out­door use. Use of a cord suitable for out-

door use reduces the risk of electric
shock.

f) If operating a power tool in a damp loca-

tion is unavoidable, use a residual cur­rent device (RCD) protected supply. Use

of an RCD reduces the risk of electric
shock.

3) Personal safety

a) Stay alert, watch what you are doing and

use common sense when operating a
power tool. Do not use a power tool
while you are tired or under the influ­ence of drugs, alcohol or medication. A

moment of inattention while operating
power tools may result in serious person­al injury.

b) Use personal protective equipment. Al-

ways wear eye protection. Protective

equipment such as dust mask, non-skid
safety shoes, hard hat, or hearing protec­tion used for appropriate conditions will
reduce personal injuries.

c) Prevent unintentional starting. Ensure

the switch is in the off-position before
connecting to power source and/or bat­tery pack, picking up or carrying the
tool. Carrying power tools with your fin-

ger on the switch or energising power
tools that have the switch on invites acci­dents.

d) Remove any adjusting key or wrench be-

fore turning the power tool on. A wrench

or a key left attached to a rotating part of
the power tool may result in personal inju­ry.

e) Do not overreach. Keep proper footing

and balance at all times. This enables

better control of the power tool in unex­pected situations.

f) Dress properly. Do not wear loose cloth-

ing or jewellery. Keep your hair, clothing
and gloves away from moving parts.

Loose clothes, jewellery or long hair can
be caught in moving parts.

g) If devices are provided for the connec-

tion of dust extraction and collection fa­cilities, ensure these are connected and
properly used. Use of dust collection can

reduce dust-related hazards.

4) Power tool use and care

a) Do not force the power tool. Use the cor-

rect power tool for your application. The

correct power tool will do the job better
and safer at the rate for which it was de­signed.

b) Do not use the power tool if the switch

does not turn it on and off. Any power

tool that cannot be controlled with the
switch is dangerous and must be re­paired.

c) Disconnect the plug from the power

source and/or the battery pack from the
power tool before making any adjust­ments, changing accessories, or storing
power tools. Such preventive safety

measures reduce the risk of starting the
power tool accidentally.

d) Store idle power tools out of the reach of

children and do not allow persons unfa­miliar with the power tool or these in­structions to operate the power tool.

Power tools are dangerous in the hands of
untrained users.

e) Maintain power tools. Check for mis-

alignment or binding of moving parts,
breakage of parts and any other condi­tion that may affect the power tool’s op­eration. If damaged, have the power tool
repaired before use. Many accidents are

caused by poorly maintained power tools.

f) Keep cutting tools sharp and clean. Prop-

erly maintained cutting tools with sharp
cutting edges are less likely to bind and
are easier to control.

g) Use the power tool, accessories and tool

bits etc. in accordance with these in­structions, taking into account the work­ing conditions and the work to be per­formed. Use of the power tool for

operations different from those intended
could result in a hazardous situation.

5) Service

a) Have your power tool serviced by a qual-

ified repair person using only identical
replacement parts. This will ensure that

the safety of the power tool is maintained.

Hammer Safety Warnings

f Wear ear protectors. Exposure to noise can

cause hearing loss.

f Use auxiliary handle(s), if supplied with the

tool. Loss of control can cause personal in-

jury.

f Hold power tool by insulated gripping sur-

faces, when performing an operation where
the cutting accessory or fastener may con­tact hidden wiring. Cutting accessory and

fasteners contacting a “live” wire may make
exposed metal parts of the power tool “live”
and could give the operator an electric
shock.

f Use suitable detectors to determine if utili-

ty lines are hidden in the work area or call
the local utility company for assistance.

Contact with electric lines can lead to fire
and electric shock. Damaging a gas line can
lead to explosion. Penetrating a water line
causes property damage or may cause an
electric shock.

f When working with the machine, always

hold it firmly with both hands and provide
for a secure stance. The power tool is guided

more secure with both hands.

f Secure the workpiece. A workpiece clamped

with clamping devices or in a vice is held
more secure than by hand.

f Always wait until the machine has come to

a complete stop before placing it down. The

tool insert can jam and lead to loss of control
over the power tool.

(see figure A)

The auxiliary handle 11 can be set to any posi­tion for a secure and low-fatigue working pos­ture.

1 619 P09 069 | (12.10.10) Bosch Power Tools

– Turn the bottom part of the auxiliary handle

11 in counterclockwise direction and swivel
the auxiliary handle 11 to the desired posi­tion. Then retighten the bottom part of the
auxiliary handle 11 by turning in clockwise di­rection.

Adjusting the Drilling Depth (see figure B)

The required drilling depth X can be set with the
depth stop 10.

– Press the button for the depth stop adjust-

ment 9 and insert the depth stop into the
auxiliary handle 11.

OBJ_BUCH-1281-002.book Page 9 Tuesday, October 12, 2010 3:05 PM

English | 9

– The knurled surface of the depth stop 10

must face downward.

– Insert the SDS-plus drilling tool to the stop

into the SDS-plus tool holder 1. Otherwise,
the movability of the SDS-plus drilling tool
can lead to incorrect adjustment of the drill­ing depth.

– Pull out the depth stop until the distance be-

tween the tip of the drill bit and the tip of the
depth stop correspond with the desired drill­ing depth X.

Selecting Drill Chucks and Tools

For hammer drilling and chiselling (chiselling
only with MV 200 accessory), SDS-plus tools are
required that are inserted in the SDS-plus drill
chuck.

For drilling without impact in wood, metal, ce­ramic and plastic as well as for screwdriving,
tools without SDS-plus are used (e.g., drills
with cylindrical shank). For these tools, a key­less chuck or a key type drill chuck are required.

Changing the Key Type Drill Chuck

To work with tools without SDS-plus (e.g., drills
with cylindrical shank), a suitable drill chuck
must be mounted (key type drill chuck or key­less chuck, accessories).

Removing the Key Type Drill Chuck

– Push the locking sleeve 3 toward the rear

and pull out the key type drill chuck 14.

Changing the Tool

The dust protection cap 2 largely prevents the
entry of drilling dust into the tool holder during
operation. When inserting the tool, take care
that the dust protection cap 2 is not damaged.

f A damaged dust protection cap should be

changed immediately. We recommend hav­ing this carried out by an after-sales serv­ice.

Inserting SDS-plus Drilling Tools (see figure D)

The SDS-plus drill chuck allows for simple and
convenient changing of drilling tools without the
use of additional tools.

– Clean and lightly grease the shank end of the

tool.

– Insert the tool in a twisting manner into the

tool holder until it latches itself.

– Check the latching by pulling the tool.

As a requirement of the system, the SDS-plus
drilling tool can move freely. This causes a cer­tain radial run-out at no-load, which has no ef­fect on the accuracy of the drill hole, as the drill
bit centres itself upon drilling.

Mounting the Key Type Drill Chuck
(see figure C)

– Screw the SDS-plus adapter shank 15 into a

key type drill chuck 14. Secure the key type
drill chuck 14 with the securing screw 13.

Please observe that the securing screw has
a left-hand thread.

Inserting the Key Type Drill Chuck
(see figure C)

– Clean the shank end of the adapter shank

and apply a light coat of grease.

– Insert the key type drill chuck with the adapt-

er shank into the tool holder with a turning
motion until it automatically locks.

– Check the locking effect by pulling the key

type drill chuck.

Bosch Power Tools 1 619 P09 069 | (12.10.10)

Removing SDS-plus Drilling Tools
(see figure E)

– Push back the locking sleeve 3 and remove

the tool.

Inserting Drilling Tools without SDS-plus

Note: Do not use tools without SDS-plus for

hammer drilling! Tools without SDS-plus and
their drill chucks are damaged by hammer drill­ing.

– Insert a key type drill chuck 14 (see “Chang-

ing the Key Type Drill Chuck”, page 9).

– Open the key type drill chuck 14 by turning

until the tool can be inserted. Insert the tool.

– Insert the chuck key into the corresponding

holes of the key type drill chuck 14 and clamp
the tool uniformly.

– Set the selector switch 8 to the “Drilling”

symbol.

Removing Drilling Tools without SDS-plus

– Turn the sleeve of the key type drill chuck 14

with the drill chuck key in anticlockwise di­rection until the drilling tool can be removed.

Dust Extraction with the Dust Extrac­tion Attachment (Accessory)

f Dusts from materials such as lead-containing

coatings, some wood types, minerals and
metal can be harmful to one’s health. Touch­ing or breathing-in the dusts can cause aller­gic reactions and/or lead to respiratory infec­tions of the user or bystanders.
Certain dusts, such as oak or beech dust, are
considered as carcinogenic, especially in
connection with wood-treatment additives
(chromate, wood preservative). Materials
containing asbestos may only be worked by
specialists.

– As far as possible, use a dust extraction

system suitable for the material.

– Provide for good ventilation of the work-

ing place.

– It is recommended to wear a P2 filter-

class respirator.

Observe the relevant regulations in your
country for the materials to be worked.

f Prevent dust accumulation at the work-

place. Dusts can easily ignite.

Mounting the Dust Extraction Attachment
(see figure F)

For dust extraction, the dust extraction attach­ment (accessory) is required. When drilling, the
dust extraction attachment retracts so that the
attachment head is always close to the surface
at the drill hole.

– Press the button for depth stop adjustment 9

and remove the depth stop 10. Press button
9 again and insert the dust extraction attach­ment into the auxiliary handle 11 from the
front.

– Connect an extraction hose (diameter

19 mm, accessory) to the extraction sleeve
16 of the dust extraction attachment.

The vacuum cleaner must be suitable for the ma­terial being worked.

When vacuuming dry dust that is especially det­rimental to health or carcinogenic, use a special
vacuum cleaner.

Adjusting the Drilling Depth on the Dust Ex­traction Attachment (see figure G)

The required drilling depth X can also be adjust­ed when the dust extraction attachment is
mounted.

– Insert the SDS-plus drilling tool to the stop

into the SDS-plus tool holder 1. Otherwise,
the movability of the SDS-plus drilling tool
can lead to incorrect adjustment of the drill­ing depth.

– Loosen the wing bolt 20 on the dust extrac-

tion attachment.

– Without switching the power tool on, apply it

firmly to the drilling location. The SDS-plus
drilling tool must face against the surface.

– Position the the guide pipe 21 of the dust ex-

traction attachment in its holding fixture in
such a manner that the head of the dust ex­traction attachment faces against the surface
to be drilled. Do not slide the guide pipe 21
further over the telescopic pipe 19 of the
dust extraction attachment than required, so
that as much as possible of the scale 19 on
the telescopic pipe remains visible.

– Retighten the wing bolt 20 again. Loosen the

clamping screw 17 on the depth stop of the
dust extraction attachment.

–Move the depth stop 18 on the telescopic

pipe 19 in such a manner that the
clearance X shown in the figure corresponds
with the required drilling depth.

– Tighten the clamping screw 17 in this posi-

tion.

Operation

Starting Operation

f Observe correct mains voltage! The voltage

of the power source must agree with the
voltage specified on the nameplate of the
machine. Power tools marked with 230 V
can also be operated with 220 V.

Setting the Operating Mode

With the selector switch for drilling/hammer
drilling 8, the operating mode of the machine is
selected.

Note: Change the operating mode only when the
machine is switched off! Otherwise, the ma­chine can be damaged.

– To change the operating mode, press the re-

lease button 7 and turn the drilling/hammer
drilling selector switch 8 to the desired posi­tion until it can be heard to latch.

Position for hammer drilling in
concrete or stone as well as for
chiselling (chiselling only with the
MV 200 accessory)

Position for drilling without impact
in wood, metal, ceramic and plastic
as well as for screwdriving and
thread cutting

Reversing the Rotational Direction
(GBH 2-23 RE)

The rotational direction switch 4 is used to re­verse the rotational direction of the machine.
However, this is not possible with the On/Off
switch 6 actuated.

Right rotation: Turn the selector switch for
drilling/hammer drilling 4 on both sides to
the stop in the position .

Left rotation: Turn the selector switch for
drilling/hammer drilling 4 on both sides to
the stop in the position .

Set the direction of rotation for hammer drilling,
drilling and chiselling always to right rotation.

Switching On and Off

–To start the machine, press the On/Off

switch 6.

–To lock the On/Off switch, keep it pressed

and additionally push the lock-on button 5.

–To switch off the machine, release the

On/Off switch 6. When the On/Off switch 6
is locked, press it first and then release it.

Setting the Speed/Impact Rate
(GBH 2-23 E/RE)

The speed/impact rate of the switched on pow­er tool can be variably adjusted, depending on
how far the On/Off switch 6 is pressed.

Light pressure on the On/Off switch 6 results in
low speed/impact rate. Further pressure on the
switch increases the speed/impact rate.

Safety Clutch

f If the tool insert becomes caught or

jammed, the drive to the drill spindle is in­terrupted. Because of the forces that occur,
always hold the power tool firmly with both
hands and provide for a secure stance.

f If the power tool jams, switch the machine

off and loosen the tool insert. When switch­ing the machine on with the drilling tool
jammed, high reaction torques can occur.

Working Advice

f Before any work on the machine itself, pull

the mains plug.

Chiselling

For chiselling, a MV 200 SDS-plus chiselling at­tachment (accessory), which is inserted into the
SDS-plus tool holder 1, is required.

Inserting Screwdriver Bits (see figure H)

f Apply the power tool to the screw/nut only

when it is switched off. Rotating tool inserts

can slip off.

To work with screwdriver bits, a universal bit
holder 22 with SDS-plus shank (accessory) is re­quired.

– Clean the shank end of the adapter shank

and apply a light coat of grease.

安全规章

电动工具通用安全警告

阅读所有警告和所有说明 ! 不遵照以下警告

和说明会导致电击、着火和／或严重伤害。

保存所有警告和说明书以备查阅。

在所有下列的警告中术语 " 电动工具 " 指市电驱动 （有
线）电动工具或电池驱动 （无线）电动工具。

1) 工作场地的安全

a) 保持工作场地清洁和明亮。 混乱和黑暗的场地会

引发事故。

b) 不要在易爆环境，如有易燃液体、气体或粉尘的

环境下操作电动工具。 电动工具产生的火花会点

燃粉尘或气体。

c) 让儿童和旁观者离开后操作电动工具。 注意力不

集中会使你失去对工具的控制。

2) 电气安全

a) 电动工具插头必须与插座相配。绝不能以任何方

式改装插头。 需接地的电动工具不能使用任何转
换插头。未经改装的插头和相配的插座将减少电
击危险。

3) 人身安全

a) 保持警觉，当操作电动工具时关注所从事的操作

并保持清醒。当你感到疲倦，或在有药物、酒精
或治疗反应时，不要操作电动工具。 在操作电动

工具时瞬间的疏忽会导致严重人身伤害。

b) 使用个人防护装置。始终佩戴护目镜。 安全装
