Using a Brushcutter With a Trimmer Head

Maintenance

You may install one of several types of Shin- daiwa trimmer heads on your TC350/B450 trimmer or brushcutter, each with features for specific applications and/or operational requirements.

For proper operation, always refer to the instructions accompanying the trimmer head being used. Available trimmer head styles include:

Semi-automatic.Trimmer line is indexed when the operator taps the trim- mer head on the ground during opera- tion.

Manual. The operator indexes line man- ually with the grass trimmer stopped.

Fixed. The operator must stop the unit and add new lengths of trimmer line manually.

Flail. This device, designed for clearing weeds and light brush, features three nylon blades attached to the head by pivots.

CAUTION!

Do not push the rotating line into trees, wire fences or any material that could tangle or break line ends.

Engine Operating Speeds

Operate at full throttle while cutting grass.

CAUTION!

Operation at low rpm can lead to pre- mature clutch failure.

Trimming and Mowing Grass

Hold the grass trimmer so the trimmer head is angled slightly into the area to be cut. To ensure maximum trimmer-line service life, cut only with the tip of the trim- mer line. Cut grass by swinging the unit's trimmer head from left to right. Keep the trimmer head horizontal.
