81 shirts The Rapid Micro (RM) chain is a universal use, comfort type chain, with low level of vibrations, soft cutting, low tendency to bounce. Particularly good driving characteristics and high cutting performance. Relatively easy to resharpen. The profile of the cutting tooth is of the round tooth type (also called semi-chisel). OILOMATIC SYSTEM Thin oil grooves in the chain guide links collect lubricant and flow it to the joints. On both sides of the guide links there are numerous recesses in which the lubricant collects. Thus the oil is better distributed on the sliding surfaces of the bar, improving lubrication by 10%. So the life of the chain increases. COMFORT CHAIN The teeth and connection links are made in relief on the rear part of the sliding track. The space between the tooth and the bar allows the teeth to tilt back with a smooth movement during cutting. When the cutting edge comes into contact with the wood, the tooth tilts back with a smooth movement, and a significant part of the impact energy is absorbed by the chain. Depending on the chain used, vibrations are reduced by up to approximately 30% during cutting. VERSION 3 An upwardly elongated guide link, the humped guide link, guides the tooth softly and smoothly into the wood, allowing: an increased silent operation of the chain; reducing the tendency to rebound. Use: felling, cutting to length, limbing and all cutting jobs that are called upon to carry out in the agricultural, construction and forestry sectors. Models: STIHL: MS 271, MS 261
