Common questions
Insert a compatible charged battery, then follow the model’s manual for the safety lock and trigger sequence. Controls differ across models, so use the instructions for the exact trimmer.
The process depends on the fitted mowing head. Identify the head model and follow its manual for line diameter, winding direction and feed method.
Switch off and remove the battery before servicing. Then reload the line according to the mowing-head instructions; do not assume every STIHL head uses the same procedure.
The trimmer model, battery and charger bundle, and included accessories affect the package. Compare like-for-like kits and check current authorized-retailer listings.
Compatibility depends on the model and attachment system. Confirm the approved accessories in the manufacturer documentation for your specific trimmer.
