OPERATING INSTRUCTIONS

OPERATING THE TRIMMER

WARNING: Always wear eye, hearing, foot and

body protection to reduce the risk of injury when operating this unit.

Clear the area to be cut before each use. Remove all objects such as rocks, broken glass, nails, wire, or string which can be thrown or become entangled in the cutting attachment. Clear the area of children, bystanders, and pets. At a minimum, keep all children, bystanders and pets outside a 50 feet (15m) radius; there still may be a risk to bystanders from thrown objects. Bystanders should be encouraged to wear eye protection. If you are approached, stop the motor and cutting attachment immediately.

NOTE: Remove protective tape from the line cut-off blade before operating trimmer.

ADJUSTING TRIMMING LINE LENGTH

The bump head allows the operator to release more trimming line without stopping the motor. As line becomes frayed or worn, additional line can be released by lightly tapping the trimming head on the ground while operating the trimmer (Fig. 9).

Bump Head

Fig. 9

NOTE: Always keep the trimming line fully extended. Line release becomes more difficult as cutting line becomes shorter.

CAUTION: Do not remove or alter the line cutting blade

assembly. Excessive line length will make the unit overheat. This may lead to serious personal injury or damage to the unit.

Each time the head is bumped, approximately 1 inch (25.4 mm) of trimming line is released. A blade in the string guard will cut the line if excess line is released.

For best results, tap the head on bare ground or hard soil. If line release is attempted in tall grass, the motor may overheat. Always keep the trimming line fully extended. Line release becomes more difficult as the cutting line becomes shorter.

TIPS FOR BEST TRIMMING RESULTS

•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 motor.

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

•Following the trimming techniques previously explained

•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. 10).
