STIHL recommends a STIHL servicing dealer.

Firmly tighten down the cylinder base screws of professional saws (3.4 kW or more) after 10 to 20 hours of operation.
The following maintenance intervals apply for normal operating conditions only. If your daily working
time is longer or operating conditions are difficult (very dusty work area, resin-rich wood, tropical
wood, etc.), shorten the specified intervals accordingly. If you only use the saw occasionally, extend
the intervals accordingly.
