The automatic chain lubrication with variable-fl ow oil pump
and maintenance-free electronic ignition ensure trouble-free
operation, while the hand-saving anti-vibration system and ergo-
nomic grips and controls make work easier, safer, and less tiring
for the user.

the latest safety features and meet all national and international
