STIHL - 4238-200-0040 - Petrol Cut-Off Saw TS 420 4.4 hp

Universal cutter for construction work. Grinding wheel with a diameter of 350 mm for cuts up to 125 mm deep. The STIHL anti-vibration system ensures precise and comfortable guidance of the cutter. The long-life air filter system guarantees long service intervals. Ergonomic starting thanks to the use of a decompression valve. Hand-guided or on the FW 20 guide cart. Semi-automatic V-belt tensioning system. Extends belt life. Semi-automatic STIHL belt tensioning makes re-tensioning the drive belt easier. Constant tension extends the life of the belt and bearing. For more detailed information on re-tensioning, refer to the operating instructions for the power tool. Lower maintenance. The adjustment system in the carburetor, the compensator, by equalizing pressure, ensures that despite increasing air filter contamination, engine power, exhaust quality, and fuel consumption remain almost unchanged for a long time. Therefore, the air filter only needs to be cleaned after a clear drop in performance. This allows long periods of maintenance-free operation. Manual fuel pump. Fewer starting strokes. The manual fuel pump reduces the number of starting strokes and thus speeds up the starting process. This is especially helpful after longer periods of non-use. To do this, operate the pump several times before starting. This ensures there is enough gasoline in the carburetor during startup. STIHL 2-Mix engine. Exceptional performance. This 2-stroke engine is designed to require infrequent maintenance and to consume fuel efficiently even at high power. A mixture of gasoline and engine oil should be used as fuel. The STIHL 2-Mix engine meets the requirements of the strict EU exhaust emissions directive, level V. STIHL anti-vibration system. Provides more comfortable work. When increasing the power of the device, vibrations are generated that are particularly noticeable in the handle area. The buffer and spring elements of the STIHL anti-vibration system reduce the transmission of engine vibrations to the handle area and thus to the user's body. Effect: The device sits more comfortably in the hand, and work is much less tiring. Long-life air filter system. The long-life air filter system with a pre-cyclone filter ensures that 80% of the dust particles in the drawn-in air are separated already in the first filtration stage. Dust particles do not settle - as is the case with conventional filter systems - on the foam filter, but are separated and discharged back to the outside. This eliminates the need to clean the foam filter. Manual decompression. Easy starting. The decompression valve makes starting the device easier. Opening the valve during startup releases part of the compressed mixture from the cylinder. This protects the starting system and requires less force on the starter rope. Water connection. Provides dust binding and cooling. During operation with the device, a constant water supply is provided to flush the cutting disc. It is used for dust binding and cooling the cut. Thanks to the water connection directly to the device, flushing is easy and constantly ensured. Magnesium alloy guard. Low weight and good stability. The cutting disc guard prevents the user from being struck by ejected material and cooling water coming from the cutting disc. The guard made of magnesium alloy casting is extremely light and durable.
