OPERATION OPERATING YOUR TRIMMER Before operating the unit, stand in the operating posi tion (Fig. 15). Check for the following: • The operator is wearing eye protection and proper clothing. • With a slightly-bent right arm, the operator's right hand is holding the shaft grip. • The operator's left arm is straight, the left hand hold ing the handle. • The unit is at waist level. • The cutting attachment is parallel to the ground and easily contacts the grass without the need to bend over. ADVANCING THE CUTTING LINE String advance is controlled by tapping the string head on grass while running engine at full throttle. 1. Run engine at full throttle. 2. Tap the knob on ground to advance string. The string advances each time the knob is tapped. Do not hold the knob on the ground. TIPS FOR BEST TRIMMING RESULTS • For best trimming results, operate unit at full throttle. • Keep the cutting attachment parallel to the ground. • Do not force the cutting attachment. Allow the tip of the line to do the cutting, especially along walls. Cutting with more than the tip will reduce cutting ef ficiency and may overload the engine. • Cut grass over 8 inches (200 mm) by working from top to bottom in small increments to avoid prema ture line wear or engine drag. • Slowly move the trimmer into and out of the cutting area at the desired height. Move either in a forwardbackward or side-to-side motion. Cutting shorter lengths produces the best results. • Trim only when grass and weeds are dry. • The life of your cutting line is dependent upon: 1. Proper adherence to explained trimming techniques 2. What vegetation is cut 3. Where vegetation is cut For example, the line will wear faster when trimming against a foundation wall as opposed to trimming around a tree. Some line breakage will occur from: • Entanglement with foreign matter • Normal line fatigue • Attempting to cut thick, stalky weeds • Forcing the line into objects such as walls or fence posts HOLDING THE TRIMMER Fig. 15 DECORATIVE TRIMMING Decorative trimming is accomplished by removing all vegetation around trees, posts, fences and more.
