Shorter grass or less dense growth can be cut at faster travel speeds 10 Vary the Throttle Setting According to Conditions The majority of trimming and mowing jobs will yield the best results if the Engine Throttle Control is set at the fastest engine speed Less demanding jobs that require very precise cutting will yield better results if the engine throttle is backed off somewhat to reduce engine speed For example damage to trees and or namentals can be avoided by reducing the engine speed using the lighter 130 diameter line and by keeping a safe distance away Again once you begin a particular job and get a feel for the conditions you will be able to make adjustments for the best possible results Keep the Mowed Side to Your Right as You Move Ahead The trimmer mower feeds cut materials to the right side Stay on the right side of unmowed growth as you move along NOTE If the trimmer is operated in a stationary position with the wear cup in contact with dry vegetation significant heat will result that may deform the plastic spindle or scorch vegetation 5 Maintenance A WARNING Before inspecting cleaning or servicing the machine shut off engine discon nect spark plug wire and make sure that all moving parts have come to a com plete stop Remove ignition key on electric start models Failure to follow these instructions can result in personal injury or property damage
