OPERATING INSTRUCTIONS

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

efficiency and may overload the engine.

•Cut grass over 8 inches (200 mm) by working from top to bottom in small increments to avoid premature line wear or engine drag.

•Slowly move the trimmer into and out of the cutting area at the desired height. Move either in a forward-backward 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:

•Proper adherence of explained trimming techniques

•What vegetation is cut

•Where vegetation is cut

For example, the line will wear faster when trimming against a foundation wall as opposed to trimming around a tree.

DECORATIVE TRIMMING

Decorative trimming is accomplished by removing all vegetation around trees, posts, fences and more.

Rotate the whole unit so that the cutting attachment is at a 30° angle to the ground (Fig. 19).
