5.1.1
This tool may be powered by a generator or transformer when the following conditions are fulfilled:
• The power output of the generator or transformer (in watts) must be at least twice the power rating of the
tool (see type identification plate).
• The voltage provided by the power source must remain within +5 % and –15 % of the tool's rated
voltage.
• Frequency: 50 to 60 Hz (never above 65 Hz)
• The power source must be equipped with automatic voltage regulation and starting boost.
ATTENTION
Risk of damage Switching on or switching off other power tools or appliances connected to the generator
or transformer may cause undervoltage and/or overvoltage peaks, resulting in damage to the cutter.
▶ 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 operation of the cutter and vacuum
cleaner.
5.1.2
WARNING
A damaged supply cord presents a hazard! Do not touch the supply cord or extension cord if damaged
while working. Disconnect the supply cord plug from the power outlet.
▶ Check the appliance's supply cord at regular intervals and have it replaced by a qualified specialist if
found to be damaged.
• Use only extension cords of a type approved for the application and with conductors of adequate
cross-section. Otherwise the performance of the appliance may be affected and the cord may overheat.
• Regularly check the extension cord for damage.
• Replace damaged extension cords.
• When working outdoors, use only extension cords that are approved and correspondingly marked for
this application.
