GENERAL SAFETY PRECAUTIONS Trimmer head IMPORTANT! Always ensure the trimmer line is wound tightly and evenly around the drum, otherwise the machine will generate harmful vibration. Check the cutting attachment for damage or cracks. A damaged cutting attachment should always be replaced. S Only use the recommended cutting attachments. See the section on "Technical data". Sharpening grass cutters and grass blades S See the cutting attachment packaging for correct sharpening instructions. Sharpen blades and cutters using a single--cut flat file. S Sharpen all edges equally to maintain the balance of the blade. S Smaller machines generally require small trimmer heads and vice versa. This is be- cause when clearing using trimmer line the engine must throw out the trimmer line radially from the trimmer head and overcome the resistance of the grass being cleared. S The length of the trimmer line is also important. A longer trimmer line requires greater engine power than a shorter trimmer line of the same diameter. S Make sure that the cutter on the trimmer guard is intact. This is used to cut the trimmer line to the correct length. S To increase the life of the trimmer line it can be soaked in water for a couple of days. This will make the line tougher so that it lasts longer. WARNING: Always discard a blade that is bent, twisted, cracked, broken or damaged in any other way. Never attempt to straighten a twisted blade so that it can be reused. Only use original blades of the specified type. 577387001 Rev. 2 1/6/11 English--- 9
