General rules GENERAL SAFETY PRECAUTIONS Trimmer head Only use cutting attachments with the guards we recommend! See the chapter on Technical data. IMPORTANT! Always ensure the trimmer line is wound tightly and evenly around the drum, otherwise the machine will generate harmful vibration. Keep the teeth of the blade correctly sharpened! Follow our instructions and use the recommended file gauge. An incorrectly sharpened or damaged blade increases the risk of accidents. • Only use the recommended trimmer heads and trimmer lines. These have been tested by the manufacturer to suit a particular motor size. This is especially important when a fully automatic trimmer head is used. Only use the recommended cutting attachment. See the chapter on Technical data. Check the cutting attachment for damage or cracks. A damaged cutting attachment should always be replaced. Sharpening grass knifes and grass blades • Smaller machines generally require small trimmer heads and vice versa. This is because when clearing using a line, the motor must throw out the line radially from the trimmer head and overcome the resistance of the grass being cleared. • The length of the line is also important. A longer cord requires greater engine power than a shorter line of the same diameter. • Make sure that the cutters on the trimmer guard are intact. These are used to cut the line to the correct length. • To increase the life of the line it can be soaked in water for a couple of days. This will make the line tougher so that it lasts longer. • See the cutting attachment packaging for correct sharpening instructions. Sharpen blades and cutters using a single-cut flat file. • Sharpen all edges equally to maintain the balance of the blade. 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. 10 - English
