General Power Tool Safety

Warnings

		Read all safety warnings and all
	WARNING
		instructions. 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 bat- tery-operated (cordless) power tool.

1)Work area safety

a)Keep work area clean and well lit. Cluttered 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. Distractions 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 the 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 or moving parts. Damaged or entangled cords increase the risk of electric shock.

e)When operating a power tool outdoors, use an extension cord suitable for outdoor use. Use of a cord suitable for outdoor use reduces the risk of electric shock.

f)If operating a power tool in a damp location is unavoidable, use a ground fault circuit interrupter (GFCI) or an earth leakage circuit breaker (ELCB). Use of a GFCI or an ELCB 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. Always wear eye protection. Protective equipment such as dusk 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 finger on the switch or energizing power tools that have the switch on invites accidents.

d)Remove any adjusting key or wrench before turning the power tool on. A wrench or a key that is 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 clothing or jewelry. Keep your hair, clothing, and gloves away from moving parts.

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

OBJ_BUCH-411-001.book Page 7 Friday, July 13, 2007 8:09 AM

g)If devices are provided for the connection 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 correct power tool for your application. The correct power tool will do the job better and safer at the rate for which it is designed.

b)Do not use the power tool if the switch does not turn it on or 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 misalignment 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. Properly maintained cutting tools with sharp cutting edges are less likely to bind and are easier to control.

g)Use the power tool, accessories, 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.

English | 7

5)Service

a)Have your power tool serviced by a qualified repair person using only identical replacement parts. This will ensure that the safety of the power tool is maintained.

Power Tool-specific Safety

Warnings

fWear hearing protection. Exposure to noise can cause hearing loss.

fUse the auxiliary handle supplied with the power tool. Loss of control over the power tool can cause personal injury.

fUse suitable detectors to determine if utility 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.

fHold the power tool only by the insulated gripping surfaces when performing an operation where the cutting tool may 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.

fWhen working with the power tool, always hold it firmly with both hands and provide for a secure stance. The power tool is guided more secure with both hands.

fSecure the workpiece. A workpiece clamped with clamping devices or in a vice is held more secure than by hand.

fDo not work materials containing asbestos.

Asbestos is considered carcinogenic.

fTake protective measures when dust can develop during working that is harmful to one’s health, combustible or explosive. Example:

Some dusts are regarded as carcinogenic. Wear a dust mask and work with dust/chip extraction when connectable.

fKeep your workplace clean. Blends of materials are particularly dangerous. Dust from light alloys can burn or explode.

fOperate your power tool only with the auxiliary handle 10.

The auxiliary handle 10 can be set to any position for a secure and low-fatigue working posture.

English | 9

Turn the bottom part of the auxiliary handle 10 in counterclockwise direction and swivel the auxiliary handle 10 to the desired position. Then retighten the bottom part of the auxiliary handle 10 by turning in clockwise direction.

Adjusting the Drilling Depth (see figure A)

The required drilling depth X can be set with the depth stop 11.

Press the button for the depth stop adjustment 9 and insert the depth stop into the auxiliary handle 10.

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

The knurled surface of the depth stop 11 must face downward.

Selecting the Tool Holder

For hammer drilling, SDS-plus drilling tools that can be inserted into the SDS-plus tool holder 1 are required.

For drilling without impact in wood, metal, ceramic and plastic as well as for screwdriving and tapping, use non-SDS-plus drilling tools (e. g., drill bits with cylindrical shank). A keyless drill chuck is required for such drilling tools.

Note: Do not use tools without SDS-plus for hammer drilling or chiseling! Tools without SDS-plus and their drill chucks are damaged by hammer drilling or chiseling.

The SDS-plus tool holder 1 can easily be exchanged against the quick change keyless chuck 12.

After removing, protect the tool holder 1 or the keyless replacement chuck 12 against contamination. Lightly lubricate the engaging grooves, if required.

Mounting the SDS-plus Tool Holder or the Keyless Replacement Chuck

Grasp the tool holder 1 or the keyless replacement chuck 12 completely with your hand. Slide the tool holder 1 or the keyless replacement chuck 12 with a turning motion onto the drill chuck mounting until a distinct latching noice is heard.

The tool holder 1 or the keyless replacement chuck 12 is automatically locked. Check the locking effect by pulling the tool holder.

Changing the Tool

With the SDS-plus tool holder, simple and convenient tool changing is possible without additional aids.

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 centers itself upon drilling.

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.

fA 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 C)

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.

Removing SDS-plus Drilling Tools (see figure D)

Push back the locking sleeve 3 and remove the tool.

Inserting Drilling Tools without SDS-plus (see figure E)

Note: Do not use tools without SDS-plus for hammer drilling or chiseling! Tools without SDS-plus and their drill chucks are damaged by hammer drilling or chiseling.

Insert the quick change keyless chuck 12.

Firmly hold the retaining ring of the keyless replacement chuck 12. Open the keyless replacement chuck by turning the front sleeve in the direction of the symbol “ ”.

Insert the drilling tool into the keyless replacement chuck 12. Firmly hold the retaining ring of the keyless replacement chuck 12 and turn the front sleeve in the direction of the symbol
