If your Stihl Trimmer cuts out during operation, it could be because the brushcutter is too hot. To resolve this, remove the battery and allow the brushcutter to cool down. Alternatively, there may be an electrical fault. Try removing the battery and reinserting it, then switch the brushcutter back on.

If the battery is not being charged in your Stihl Trimmer, it could be due to several reasons:
* The battery might be too warm or too cold. In this case, leave the battery inserted in the charger; charging will start automatically once the permitted temperature range is reached.
* There might be no electrical contact between the charger and the battery. Remove the battery, clean the contacts on the charger, and then reinsert the battery.

* There might be a fault in the battery. If so, do not use the battery and consult a STIHL dealer.

The STIHL FSA 30.0 is a cordless grass trimmer/lawn edge trimmer designed for mowing grass, powered by a STIHL AS battery and charged with a STIHL AL 1 charger.
Function Description
The FSA 30.0 brushcutter is designed for operating, holding, and guiding during grass trimming tasks. It features a control handle and a loop handle for user comfort and control. The device is equipped with a mowing head that houses mowing lines or cutting blades, protected by a deflector. The deflector also includes a line-limiting blade to trim surplus mowing line to the correct length during operation.

Charger Storage: The charger should be stored in a clean, dry, enclosed space, out of reach of children, with the connecting cable wound up and attached to the charger.
Blade Maintenance: Blades should be placed in water for 12 to 24 hours before use to make them supple. Worn or damaged blades must be replaced.
Mowing Head Inspection: Regularly inspect the mowing head for damage, ensure it's not jammed, and check that mowing lines or polymer blades are properly installed and within wear limits.
Deflector Inspection: Ensure the deflector is undamaged and the line limiter blade is correctly installed.
Professional Servicing: STIHL recommends having the trimmer checked by a STIHL servicing dealer every 12 months. If the trimmer, cutting attachment, battery, or charger is damaged or malfunctions, contact a STIHL authorized dealer for assistance. Users should not attempt to service or repair these components themselves.
