General Power Tool Safety Warnings

Read all safety warnings and all instruc-

tions. Failure to follow 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.

Work area safety

 Keep work area clean and well lit. Cluttered or dark areas

invite accidents.

 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.

 Keep children and bystanders away while operating a

power tool. Distractions can cause you to lose control.

Electrical safety

 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.

 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.

 Do not expose power tools to rain or wet conditions.

Water entering a power tool will increase the risk of electric

shock.

 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.

 When operating a power tool outdoors, use an exten-

sion cord suitable for outdoor use. Use of a cord suitable

for outdoor use reduces the risk of electric shock.

 If operating a power tool in a damp location is unavoid-

able, use a residual current device (RCD) protected

supply. Use of an RCD reduces the risk of electric shock.

Personal safety

 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 op-

erating power tools may result in serious personal injury.



Use personal protective equipment. Always 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.

 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 finger on the switch or en-

ergising power tools that have the switch on invites acci-

dents.

 Remove any adjusting key or wrench before turning

the power tool on. A wrench or a key left attached to a ro-

tating part of the power tool may result in personal injury.

 Do not overreach. Keep proper footing and balance at

all times. This enables better control of the power tool in

unexpected situations.

 Dress properly. Do not wear loose clothing or jewel-

lery. Keep your hair, clothing and gloves away from

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

caught in moving parts.

 If devices are provided for the connection of dust ex-

traction and collection facilities, ensure these are con-

nected and properly used. Use of dust collection can re-

duce dust-related hazards.

Power tool use and care

 Do not force the power tool. Use the correct power tool

for your application. The correct power tool will do the

job better and safer at the rate for which it was designed.

 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.

 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.

 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.

 Maintain power tools. Check for misalignment or bind-

ing 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.

 Keep cutting tools sharp and clean. Properly maintained

cutting tools with sharp cutting edges are less likely to bind

and are easier to control.

 Use the power tool, accessories and tool bits etc. in ac-

cordance 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.

Service

 Have your power tool serviced by a qualified repair per-

son using only identical replacement parts. This will en-

sure that the safety of the power tool is maintained.

Hammer Safety Warnings

 Wear ear protectors. Exposure to noise can cause hear-

ing loss.

 Use auxiliary handle(s), if supplied with the tool. Loss

of control can cause personal injury.

 Hold the tool by the insulated gripping surfaces when

performing operations where the application tool or

the screw could contact hidden wiring or its own power

cord. Contact with a “live” wire will also make exposed

metal parts of the power tool “live” and shock the operator.

 Products sold in GB only: Your product is fitted with a

BS 1363/A approved electric plug with internal fuse

(ASTA approved to BS 1362).

If the plug is not suitable for your socket outlets, it should

be cut off and an appropriate plug fitted in its place by an

authorised customer service agent. The replacement plug

should have the same fuse rating as the original plug.

The severed plug must be disposed of to avoid a possible

shock hazard and should never be inserted into a mains

socket elsewhere.

Products sold in AUS and NZ only: Use a residual current

device (RCD) with a rated residual current of 30 mA or

less.

Additional Safety and Working In-

structions

 Observe correct mains voltage! The voltage of the pow-

er 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.

 Use appropriate detectors to determine if utility lines

are hidden in the work area or call the local utility com-

pany 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 dam-

age.

 Firmly tighten the auxiliary handle, hold the machine

firmly with both hands while working and keep proper

footing and balance at all times. The machine is securely

guided with both hands.

 Secure the workpiece. A workpiece clamped with clamp-

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

 To save energy, only switch the power tool on when using

it.

 For drilling without impact in wood, metal, ceramic and

plastic as well as for screwdriving, tools without SDS-plus

are used (e.g., drill bits with cylindrical shank). For these

tools, a keyless chuck or a key type drill chuck are re-

quired.

 GBH 2-28 F: Only use quick change chucks with 3 identi-

fication grooves (standard delivery scope) or 2 identifi-

cation grooves (accessory/spare part) – see figure 1,

page 65.

– The quick change chuck is automatically locked. Check

the locking effect by pulling the quick change chuck.

 Inserting SDS-plus Drilling Tools: Check the latching by

pulling the tool.

 Replace a damaged dust protection cap immediately.

The dust protection cap largely prevents the penetration of

drilling dust into the tool holder during operation. When in-

serting the tool, pay attention that the dust protection cap

is not damaged.

 Dust from materials such as lead-containing coatings,

some wood types, minerals and metal can be harmful to

one’s health and cause allergic reactions, lead to res-

piratory infections and/or cancer. 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 working place.

– It is recommended to wear a P2 filter-class respirator.

Observe the relevant regulations in your country for the

materials to be worked.

 Prevent dust accumulation at the workplace. Dust can

easily ignite.

 If the application tool should become blocked, switch

the machine off. Loosen the application tool.

 Before switching on the power tool, make sure that the

application tool moves freely. When switching on with a

blocked drilling tool, high torque reaction can occur.

 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.

 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.

 The rapid shut-off feature (KickBack Control) provides

better control over the power tool to increase user pro-

tection compared to power tools that do not have Kick-

Back Control. The power tool will switch off if it sud-

denly and unforeseeably rotates around the drilling

axis. To restart the machine

, release the On/Off switch

and then actuate again.
