7. WARNING Machines fitted with saw blades or grass blades can be thrown violently to the side when the blade comes into contact with a fixed object This is called blade thrust A blade thrust can be violent enough to cause the machine and or operator to be propelled in any direction and possibly lose control of the machine Blade thrust can occur without warning if the machine snags stalls or binds Blade thrust is more likely to occur in areas where it is difficult to see the material being cut Avoid cutting with the area of the blade between the 12 o clock and 3 o clock positions Because of the speed of rotation of the blade blade thrust can occur if you attempt to cut thick stems with this area of the blade Before you start clearing check the clearing area the type of terrain the slope of the ground whether there are stones hollows etc Start at whichever end of the area is easiest and clear an open space from which to work Work systematically to and fro across the area clearing a width of around 4 5 m on each pass This exploits the full reach of the machine in both directions and gives the operator a convenient and varied working area to work in G a q a _ at es b Sie Wy 7 N VAY 34 i fi p Es VI T M P 1 M B 7 Fe RR N IN AV NI JEW u NY Y kal N IA A A em eene dj a a v Clear a strip around 75 m long Move your fuel can as work progresses On sloping ground you sho
