2.10 Using extension cords outdoors
When working outdoors, use only extension cords that are approved and correspondingly marked for this application.
2.11 Using a generator or transformer
This tool may be powered by a generator or transformer when the following conditions are fulfilled: The unit must
provide a power output in watts of at least twice the value printed on the type identification plate on the power tool.
The operating voltage must remain 5% and -15% of the rated voltage at all times, frequency must be in the 50
– 60 Hz range and never above 65 Hz, and the unit must be equipped with automatic voltage regulation and starting
boost.
Never operate other power tools or appliances from the generator or transformer at the same time. Where applicable,
use a generator or transformer designed for simultaneous power tool and vacuum cleaner operation. Switching other
power tools or appliances on and off may cause undervoltage and / or overvoltage peaks, resulting in damage to the
power tool.
2.12 Depth gauge (optional)
The power tool can be fitted with an optional depth gauge. This improves dust removal performance for cutting mineral
materials. The maximum cutting depth can be set with the aid of the cutting depth scale on the hood extension.
