Cutting Grass—Units equipped with a trimmer head.

OPERATION

Your Shindaiwa T272 or T272X Grass Trimmer may be equipped with one of several Shindaiwa trimmer head models, each with features for spe- cific applications and/or operational requirements.

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

nSemi-automatic. Trimmer line is indexed when the operator taps the trimmer head on the ground during operation.

nManual. The operator indexes line manually while the grass trimmer is stopped.

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

nFlail. This device, designed for clear- ing 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 the unit at full throttle while cutting grass.

WARNING!

Operation at low rpm (min-1) can lead to premature clutch failure.

about 100° to
the right (from

mer vertical as
