When using professional chainsaws (with a power output of 3.4 kW or more) for the first time, tighten the cylinder block screws after 10 to 20 hours of operation
The following maintenance intervals apply for normal operating conditions only. When working under

or longer than normal each day, the specified intervals must be shortened accordingly. If you only use
