STIHL FSA 70 R AK Battery Trimmer Kit (FA07 011 5715)

The STIHL FSA 70 R AK Battery Trimmer Kit (FA07 011 5715) makes it easier to tidy lawn edges, trim around trees and clear grass where your mower cannot reach. This 36V AK System kit includes an AK 20 battery and AL 101 charger for cordless garden care.

The adjustable loop handle helps you find a comfortable working position around garden beds and on uneven ground. Select ECO mode for lighter trimming or full power for thicker grass, then vary the speed from the control handle as you work.

Compatible Heads and Safe Use

The PolyCut 12-2 head with plastic blades is an optional alternative to the supplied AutoCut C 12-2. Use only the approved Rapid Click head, cutting material and guard combinations specified for the FSA 70 R. Plastic-blade compatibility does not establish approval for metal grass blades, brush knives, saw blades or metal-blade fitting kits.

Remove the battery before changing heads, refilling line, cleaning or servicing. Use both hands and follow the instruction manual for protective equipment, operating distances and permitted conditions. Quiet operation does not replace required hearing protection.
