Stihl KM90R 28.4cc Power UnitPowerful robust KombiEngine for demanding and frequent applications. With the patented STIHL 4-MIX engine providing fast acceleration, more power, added torque, lower noise and increased fuel efficiency when compared to a 2-stroke engine. With loop handle for difficult terrain and confined conditions. Quick release coupling for easy dismantling and changing of tools. Suitable for all KombiTools.
STIHL 4-MIX engine - You can always rely on STIHL to keep setting new benchmarks this time with 4-stroke mixed lubrication technology. The STIHL 4-MIX engine, which runs on a fuel-oil mix just like a 2-stroke, offers the benefits without the compromises of 4-stroke power. STIHL 4-MIX engine technology provides fast acceleration, more power, added torque, lower noise, reduced emissions and increased fuel efficiency to complete jobs quickly, quietly and more easily
Loop handle (R) - The loop handled grass trimmers and brushcutters are ideal for working in areas where space is limited, e.g. thinning between bushes and shrubs.
Quick-release coupling - The quick-release coupling allows the KombiSystem to be quickly dismantled into two parts for easy transport and storage and then re-assembled quickly without tools
Split shaft - With a split shaft and special toolless quick-release coupling, the KombiSystem is highly versatile, easily transported and easy to store
Multi-function control handle - Easy, comfortable thumb-operated control means the operator's hand never leaves the handle
Decompression system - The decompression valve allows some of the compression pressure in the cylinder to escape, so less force on the starter rope is needed
Goggles - It is important to protect your eyes from flying particles and harmful UV radiation. Therefore a pair of safety goggles/glasses are supplied with the the machine. Note: Additional face protection must be worn when working with brushcutters!
Electronic ignition module - This ensures reliable starting and trouble-free running. The ignition system is fully encapsulated and thus protected from damp and dirt
Anti-vibration system - Intense vibration at the handles of power tools can lead to long-term effects on blood vessels in the hands and arms. STIHL has therefore developed an effective anti-vibration system whereby the oscillations from the machine's engine are dampened which significantly reduces vibrations at the handles.
