TIPS FOR BEST TRIMMING RESULTS

The correct angle for the cutting attachment is 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 in. (200 mm.) by working from top to bottom in small increments to avoid premature line wear or engine drag.

Cut from right to left whenever possible. Cutting to the left improves the unit's cutting efficiency. Clippings are thrown away from the operator.

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;

Following the previous trimming techniques

What vegetation is being cut

Where it’s being cut

DECORATIVE TRIMMING

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

Rotate the whole unit so that the cutting attachment is at a 30° angle to the ground (Fig. 12).

Fig. 12

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