Only use the abrasive wheel approved for the type of material to be cut. There are different abrasive wheels, each specially marked. For example: TS 400 English / USA 1. Stone Also can be used for concrete, masonry, reinforced concrete and brick cutting. 2. Steel Can be used for all ferrous metal cutting. 3. Asphalt Also can be used for aggregate concrete cutting. 4. Ductile iron Also can be used for certain grades of cast iron (SG 17-24), bronze and copper cutting. For cutting composite materia

Ignited Vapors may explode. Always stop the engine and allow it to cool before filling the fuel tank. Do not smoke while filling the tank. Keep sparks and open flames at a distance from the area. NOTE: Dispose of the old fuel/oil mix in accordance to Federal, State and Local regulations. Remove fuel capWARNING: slowly to avoid injury from fuel spray. Never operate the unit without the fuel cap securely in place. Add fuel in a clean, WARNING: well ventilated outdoor area. Wipe up any spilled fuel

A 3-wire extension cord (an extension cord with a ground) that uses a NEMA type connector (parallel blade, U ground) is recommended. Extension cords are available from your local retailer. Use only round- jacketed extension cords approved for outdoor use. • This tool is double-insulated. Repair or replace damaged cords. • To reduce the risk of electrical shock, this unit has a polarized plug (one blade is wider than the other). This unit will fit with a polarized plug in one way only. If the plu

This avoids unnecessary high loads during the break-in period. As all moving parts have to bed in during the break-in period, the frictional resistances in the engine are greater during this period. The engine develops its maximum power after about 5 to 15 tank fillings. During Operation After a long period of full throttle operation, allow the engine to run for a short while at idle speed so that engine heat can be dissipated by the flow of cooling air. This protects engine- mounted components

SR 430, SR 450 English Checking the Spark Plug 000BA039 KNA Engine Running Behavior If engine running behavior is unsatisfactory even though the air filter 1 is clean and the carburetor is properly adjusted, the cause may be the muffler. Have the muffler checked for contamination (carbonization) by your servicing dealer. STIHL recommends that you have N Clean dirty spark plug. N Check electrode gap (A) and 2 servicing and repair work carried out exclusively by an authorized STIHL servicing deale

As all moving parts have to bed in during the break-in period, the frictional resistances in the engine are greater during this period. The engine develops its maximum power after about 5 to 15 tank fillings. During Operation Do not make the mixture leaner to achieve an apparent increase in power – this could damage the engine – see "Adjusting the Carburetor". Check chain tension frequently A new chain has to be retensioned more often than one that has been in use for some time. Chain cold Tensi

Have such work performed by your STIHL servicing dealer only. Wear gloves when handling or performing maintenance on the cutting attachment. Warning! Use the specified spark plug and make sure it and the ignition lead are always clean and in good condition. Always press spark plug boot snugly onto spark plug terminal of the proper size. (Note: If terminal has detachable SAE adapter nut, it must be securely attached.) A loose connection between spark plug terminal and the ignition wire connector

Control dust at the source where possible. Use good work practices, such as such as always cutting with a properly sharpened chain (which produces wood chips rather than fine dust) and operating the unit so that the wind or operating process directs any dust raised by the power tool away from the operator. Follow the recommendations of EPA / OSHA / NIOSH and occupational and trade associations with respect to dust ("particulate matter"). When the inhalation of dust cannot be substantially contro
