The following is a Google Translate version of an article on a German arborculture site. Some interesting news on the M-tronic system and new calibration techique:
Stihl has presented its new MS 462 CM chain saw for professional forestry applications. Its engine weight of only 6 kg makes it according to the manufacturer to the lightest high-performance saw in the 70 cm 3 -hub space class. Further attention is given to the further developed engine management system M-Tronic and an improved engine concept.
The system weight of the MS 462 CM, ie the weight of the untanked engine unit including cutting equipment, is just 7.3 kg with the Rollomatic ES Light guide rail with 50 cm cutting length and the 3/8 "Rapid Super saw chain. Compared to the previous model MS 461 this is a weight saving of 1.1 kg. This was made possible, among other things, by a newly designed motor unit with improved cylinder geometry. In addition, sprocket covers, crankcase and flywheel became lighter and more compact. Due to its smaller diameter and the lighter weight, the flywheel also reduces the resulting centrifugal forces, which facilitates the pivoting of the chain saw during
operation . The MS 462 CM is equally suitable as a felling and debonding saw, according to a press release.
engine
The MS 462 CM is powered by a
STIHL 2-MIX engine with 4.4 kW. Due to the new cylinder geometry with optimized combustion chamber, it should have a particularly high torque in a wide speed range. The M-Tronic engine management system, in conjunction with the new flywheel, would ensure a deceleration-free acceleration and prevent the typical "clutch fly" on the way to the maximum speed - the chain maximum speed of 106 km / h is reached in just 0.3 seconds.
Calibration in 72 seconds
New is the calibration function of the M-Tronic. The motor saw can be adapted in just 72 seconds to different locations, for example in the high mountains: simply start, idle, full throttle, finished! The environmental factors are automatically recorded and all engine system parameters are electronically controlled so that the maximum speed is always available regardless of the location. Thanks to the memory function, the adjustments are automatically saved and taken into account the next time you start. Manual corrections on the adjusting screws can be omitted.
A new feature is the lancing strip - a practical marking on the fan housing, which facilitates directional control and machine guidance in the case of cuts. In addition, the tooth length of the claws was adapted to the radius of strong trees. The saw is said to be easier to reach into the wood during cutting and can be guided particularly safely and safely, explains
Stihl .
The new HD2 air filter with radial seal has a longer service life and better filter action against
fine dust than the previous models. At the same time, the
filter can be cleaned particularly easily - either manually with water and resin solution or in the washing machine.
