Long-life filter system with cyclone pre-separation makes on site maintenance unnecessary. Extremely low vibration levels (3.9m/s²). High performance engine with stratified charge system. Compact design and optimised balance for excellent cutting and guide characteristics. For use with 300mm cutting wheel. ElastoStart, primer pump and decompression valve. Bayonet filler cap for tool free opening. Can be hand held or used with the FW 20 cart. Supplied with abrasive cutting wheel. To deter theft and aid recovery all STIHL cut-off saws come with the Datatag MicroCESAR security marking system fitted as standard.
Reduced-emission engine technology
2-stroke engine with stratified charge. A fuel-free layer of air is created between the burned charge in the combustion chamber and the fresh charge in the crankcase, reducing the amount of fuel lost during the charge cycle. This results in more power with a lower weight, up to 20% lower fuel consumption than regular 2-stroke engines and significantly reduced exhaust emissions.
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 following extended breaks in operations.
Water is supplied to the cutting wheel through the standard water connection with sprinkler system to suppress the dust produced during cutting. It is supplied to the device in such a way so as not to interfere with your work.
Pre-separation air filtration system
STIHL long-life air filtration systems with pre-separation achieve perceptibly longer filter life compared with conventional filter systems. Air drawn in is swirled. The larger, heavier particles are ejected. The pre-cleaned air is routed to the air filter via the pre-separator duct.
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.
Ergonomic grip position
The modern, ergonomic design allows each user to work with an optimal grip position. The loop handle facilitates excellent cutting comfort in any working position.
Semi automatic drive belt tensioning
Light, consistent re-tensioning increases the service life of the belts and shaft bearings.
Enhanced theft deterrent with Datatag
STIHL fit MicroCESAR security marking system, with tamper evident warning label and unique RFID transponder, to all cut-off saws. Powered by proven Datatag technologies, this system deters theft but if the worst does happen Datatag enables police to carry out simple and immediate checks on suspected stolen cut-off saws. As an added benefit Datatag technologies can also be used by owners as an asset management tool.
