Specifications

Features

Air Filter Cover

Easily remove the cover for fast and easy filter cleaning or replacement.

Anti-Vibration System

STIHL has a system for minimizing the vibration levels of handheld outdoor power equipment. The STIHL anti-vibration system helps reduce operator fatigue and provides a more comfortable working experience.

Bike Handle

When used in conjunction with a harness, the bike handle allows the machine to be easily guided, enabling a smooth horizontal mowing action to cover large areas quickly and efficiently. With soft grips for increased comfort, the bike handle provides greater control and helps reduce operator fatigue.

Fully-Lined Drive Shaft

A lined shaft provides smooth operation and less vibration.

Heavy-Duty Steel-On-Steel Clutch

Centrifugal clutch is designed to reduce slippage.

High-Tech Polymer Housing

Housings are lightweight, withstand greater impact, and are corrosion-resistant.

Made in America

A majority of STIHL products sold in America are made in America of U.S. and global materials.

Multi-Function Control Handle

Having easy access to all of the controls on one comfortable handle makes it easy to complete tasks so the operator’s hand never has to leave the handle.

Protected Choke Lever/Knob

The choke is protected to help prevent damage.

Protected Spark Arrestor Muffler

Large baffles reduce noise level and contain a screen designed to reduce the emission of sparks.

Protected Spark Plug

The spark plug is protected yet easy to change.

Protected or Enclosed Control Cables

Dangling and loose wires are eliminated.

Purge Pump Primer

By pressing the bulb, this small fuel pump delivers fuel to the carburetor, reducing the number of starting pulls needed after an extended break between uses.

Shoulder Strap / Carrying System

Using a shoulder strap or carrying system helps distribute the weight of the equipment for increased operator comfort and improved maneuverability.

Simplified Starting Procedure

To get started, users simply pump the fuel primer, set the choke, and pull the starter cord. The built-in stop switch allows the user to turn off the engine with a simple press of the button. When the engine is off, the throttle lock automatically returns to the start setting. The tool will be ready to start again when the user is ready to get back to work.

Straps and Harnesses

They distribute the load from your hands to your shoulders. They also help reduce operator fatigue and make it easier to use trimmers, brushcutters and clearing saws for extended periods.

TapAction™ AUTOCUT® Cutting Head

TapAction™ allows users to adjust the line length simply by tapping the cutting head against the ground.

Throttle Trigger Interlock

This safety feature must be depressed before the trigger can be activated.

Tool-Free Handle Adjustment

The central wing nut enables easy adjustment without the use of tools. For transportation and space-saving storage, the handle can be rotated 90°.

Upright Translucent Fuel Tank

Easily check the fuel level before starting work. If fuel is needed, the upright position makes the tank easier to fill.
