4.5 Safety Warnings Specific for Sanding

Operations:

a) Do not use excessively oversized sanding

disc paper. Follow manufacturers

recommendations when selecting sanding

paper. Larger sanding paper extending beyond the

sanding pad presents a laceration hazard and may

cause snagging, tearing of the disc or kickback.

4.6 Safety Warnings Specific for Wire

Brushing Operations:

a) Be aware that wire bristles are thrown by the

brush even during ordinary operation. Do not

overstress the wires by applying excessive

load to the brush. The wire bristles can easily

penetrate light clothing and/or skin.

b) If the use of a guard is recommended for wire

brushing, do not allow any interference of the

wire wheel or brush with the guard. Wire wheel

or brush may expand in diameter due to work load

and centrifugal forces.

4.7 Additional Safety Instructions

WARNING – Always wear protective

goggles.

Use elastic cushioning layers if they have been

supplied with the abrasive and if required.

Observe the specifications of the tool or accessory

manufacturer! Protect the discs from grease or

impacts!

Grinding wheels must be stored and handled with

care in accordance with the manufacturer's

instructions.

Never use parting grinder discs for roughing work!

Do not apply pressure to the side of parting grinder

discs.

The workpiece must lay flat and be secured against

slipping, e.g. using clamps. Large workpieces must

be sufficiently supported.

If accessories with threaded inserts are used, the

end of the spindle may not touch the base of the

hole on the grinding tool. Make sure that the thread

in the accessory is long enough to accommodate

the full length of the spindle. The thread in the

accessory must match the thread on the spindle.

See page 3 and chapter 13. Technical

Specifications for more information on the spindle

length and thread.

During machining, of metals in

particular, conductive dust can form

deposits inside the machine. This can lead to the

transfer of electrical energy onto the machine

housing. This can mean a temporary danger of

electric shocks. This is why it is necessary when the

machine is running to blow compressed air through

the rear ventilation slots of the machine regularly,

frequently and thoroughly. Here, the machine must

be held firmly.

We recommend using a stationary extractor system

and connecting a residual current circuit-breaker

(FI) upstream. When the angle grinder is shut down

via the FI circuit-breaker, it must be checked and

cleaned. See chapter 9. Cleaning for more

information on cleaning the motor.

Dust from material such as paint containing lead,

some wood species, minerals and metal may be

harmful. Contact with or inhalation of the dust may

cause allergic reactions and/or respiratory diseases

to the operator or bystanders.

Certain kinds of dust are classified as carcinogenic

such as oak and beech dust especially in

conjunction with additives for wood conditioning

(chromate, wood preservative). Material containing

asbestos must only be treated by specialists.

- Where the use of a dust extraction device is

possible it shall be used.

- The work place must be well ventilated.

- The use of a dust mask of filter class P2 is

recommended.

Follow national requirements for the materials you

want to work with.

Materials that generate dusts or vapours that may

be harmful to health (e.g. asbestos) must not be

processed.

When working in dusty conditions, ensure that

ventilation openings are not blocked. If it becomes

necessary to remove dust, first disconnect the

power tool from the mains supply (use non-metallic

objects) and avoid damaging internal components.

Damaged, eccentric or vibrating tools must not be

used.

Avoid damage to gas or water pipes, electrical

cables and loadbearing walls (static).

Connect a FI circuit-breaker with max. release

current (30 mA) upstream when using the machine

outdoors!

Pull the plug out of the socket before any making

adjustments, converting or servicing the machine.

A damaged or cracked additional handle must be

replaced. Never operate a machine with a defective

additional handle.

A damaged or cracked safety guard must be

replaced. Never operate a machine with a defective

safety guard.

This power tool is not suitable for polishing work.

Improper use of the machine will void the warranty!

The motor may overheat and damage the electric

power tool. We recommend using our angle

polisher for polishing work.
