In observance of the European 
Directive, on Waste Electric and 
Electronic Equipment and its

ENE048-1 

Intended use

 

The tool is intended for grinding, sanding and cutting of 
metal and stone materials without the use of water. 

ENF002-2 

Power supply

 

The tool should be connected only to a power supply of 
the same voltage as indicated on the nameplate, and can 
only be operated on single-phase AC supply. They are 
double-insulated and can, therefore, also be used from 
sockets without earth wire. 

 
 
 
 
 
 

For model GA7050, GA9050 

ENF100-1 

For public low-voltage distribution systems of 
between 220 V and 250 V.

 

Switching operations of electric apparatus cause voltage 
fluctuations. The operation of this device under 
unfavorable mains conditions can have adverse effects 
to the operation of other equipment. With a mains 
impedance equal or less than 0.22 Ohms it can be 
presumed that there will be no negative effects. The 
mains socket used for this device must be protected with 
a fuse or protective circuit breaker having slow tripping 
characteristics. 

GEA005-3 

General Power Tool Safety 
Warnings 

 

WARNING Read all safety warnings and all 

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 battery-operated 
(cordless) power tool. 

Work area safety 

1. 

Keep work area clean and well lit.

 Cluttered or 

dark areas invite accidents. 

2. 

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. 

3. 

Keep children and bystanders away while 
operating a power tool.

 Distractions can cause 

you to lose control.
