STIHL Anti-vibration system
Precisely calculated spring elements dampen down vibrations from the engine to a minimum, reducing fatigue. Image shows HS 81.
Cutting variation (R)
The R variations of the STIHL HS 81 and STIHL HS 86 are designed specifically for large volume cutting. They feature a cutting blade with wide tooth spacing and longer tooth height. The gearing allows a high cutting power at medium stroke rate. The R variations provide the possibility of cutting of thicker branches and completing clearing work faster and more easily.
Dual ground blade system provides a clean cut. Excellent for cutting stronger, thicker branches.
Swivelling multi function handle
The handle rotates around through 90° to the left and right, ensuring the best cutting position at all times. HS 81 and HS 86
Electronic ignition module
This ensures reliable starting and trouble-free running. The ignition system is fully encapsulated and thus proof against damp and dirt.
Manual fuel pump (Purger)
A small fuel pump delivers fuel to the carburettor at the touch of a button. This reduces the number of starting strokes required from a cold start.
