English Risk of Kickout (Blade Thrust) with all Rigid Cutting Blades Using the Grass Cutting Blade 002BA177 KN 002BA135 KN 002BA355 KN Warning! Three rectangular wear limit marks are applied to the base (periphery) of the PolyCut. To reduce the risk of serious injury from breakage of the head or blades, the PolyCut must not be used when it has worn as far as one of these marks. It is important to follow the maintenance instructions supplied with the head. STIHL FixCut mowing head Uses pre-cut lengths of nylon line. Observe wear indicators. Do not continue using the mowing head if the raised moldings (1) on the base are missing or worn - see right illustration above. The mowing head may otherwise shatter and flying objects could result in injury to the operator or bystanders. Install a new mowing head. Warning! Kickout (blade thrust) is the sudden and uncontrolled motion towards the operator's right or rear that can occur when the shaded area (especially the darkly shaded area) of a rotating blade comes in contact with a solid rigid object like a tree, rock, bush or wall. The rapid counterclockwise rotation of the blade may be stopped or slowed, and the cutting attachment may be thrown to the right or to the rear. This kickout (blade thrust) may cause loss of control of the power tool and may result in serious or fatal injury to the operator or bystanders. To reduce the risk of injury, extreme caution should be used when cutting with the shaded area of any rigid blade. All kinds of grass and weeds can be easily cut with the grass cutting blade. The power tool is swept in an arc similar to a scythe. Warning! To reduce the risk of serious or fatal injury from blade breakage, never attempt to use this blade to cut woody materials. The 4-tooth grass cutting blade is intended to cut grass and weeds. It has 4 cutting knives with cutting edges on both sides, i.e. front and rear. When the cutting edges on one side become dull, the blade can be turned over to utilize the cutting edges on the other side. The 8-tooth grass cutting blade is recommended for cutting fern or reed. Both types of grass cutting blade have to be resharpened when all cutting edges are dull. Using the Brush Knife When fitted to the power tool, the brush knife is suitable for applications ranging from cutting matted grass to clearing weeds, wild growth and scrub. 14 FS 110, FS 110 R
