Common questions
Install the guard and approved line, fit a charged compatible battery, and wear eye protection. Start and advance line as directed in the exact model manual, keeping the head clear of people and obstacles.
The total depends on the trimmer model and whether the battery and charger are included. Check a current STIHL dealer listing for the bundle you need.
Choose by yard size, vegetation, cutting width and battery platform. For longer sessions, compare manufacturer runtime information for the specific battery included rather than relying on voltage alone.
Remove the battery before cleaning. Brush grass and debris from the guard and head, and follow the manual for the shaft and housing; do not wash electrical parts.
