STIHL KM 94 RC-E Petrol KombiEngine

The STIHL KM 94 RC-E Petrol KombiEngine is a lightweight, professional-grade power unit designed to drive the extensive STIHL KombiSystem attachment range. Combining a powerful 24.1 cc STIHL 2-MIX engine with low weight and excellent fuel efficiency, it provides a versatile solution for contractors, landscapers and estate maintenance professionals who require one engine capable of tackling multiple tasks.

Producing 0.9 kW (1.2 hp) and weighing just 4.0 kg (without fuel or attachment), the KM 94 RC-E delivers an excellent balance of power and manoeuvrability. Its compact design makes it ideal for prolonged use, helping to reduce operator fatigue while maintaining the performance needed for demanding commercial applications.

A key feature of the KM 94 RC-E is STIHL ECOSPEED, which allows the engine speed to be adjusted to suit the task. By limiting maximum RPM during lighter work, users benefit from lower fuel consumption, reduced engine wear, quieter operation and improved control. Combined with the efficient STIHL 2-MIX engine, this helps minimise running costs while meeting modern emissions standards.

Starting is made simple with STIHL ErgoStart, significantly reducing the effort required to pull the starter cord. A manual fuel pump and electronic ignition system further improve starting reliability, particularly after storage or extended periods between use.

The integrated anti-vibration system isolates the engine from the handles, increasing operator comfort during extended working periods. A quick-release coupling enables attachments to be changed in seconds without tools, allowing users to move easily between tasks such as grass trimming, hedge cutting, pole pruning, edging, sweeping and leaf blowing using a single power unit.
