English 12 Operating the TrimmerFSA 90 R► Connect the carrying ring (2) to the carabiner (1).If you are using a mowing head:► Hold the trimmer with one hand on the control handle – wrap your thumb around the control handle.► Hold the trimmer with your other hand on the loop handle – wrap your thumb around the loop handle.If you are using a metal cutting attachment:► Hold the trimmer with your right hand on the control handle – wrap your thumb around the control handle.► Hold the trimmer with your left hand on the loop handle – wrap your thumb around the loop handle.

12.2 Setting Power Level

The power level is infinitely variable to suit the application. The higher the power level, the faster the cutting attachment can run.The selected power level affects the battery’s runtime. The lower the power level, the longer the battery’s runtime.Turning the set wheel (1) in the minus (‘–’) direction reduces the trigger’s travel. The power level is lower. The cutting attachment rotates at a lower RPM.Turning the set wheel (1) in the plus (‘+’) direction increases the trigger’s travel. The power level is higher. The cutting attachment rotates at a higher RPM.

English 13 After Finishing Work ► Turn the set wheel (1) to the required position.

The cutting height is determined by the distance of the cutting attachment from the ground. ► Swing the trimmer back and forth in an arc (A). ► If you are using a metal cutting attachment: Mow with the left-hand side on the metal cutting attachment (B). ► Walk slowly and steadily forwards.
