CUTTING PROCEDURES

Locking tool

OPERATING INSTRUCTIONS NYLON
LINE

1. Always use the end of the line for cutting.

Forcing the cutter head too close to the work
will result in reduced efficiency and broken line.

2. Maintain the line at the recommended length of

12.5 to 15 cm ( 5 to 6 in).
A longer line will reduce engine speed, a
shorter line may result in engine damage.

3. The trimmer head rotates counterclockwise.

Always cut with the head tilted to the right to
deflect debris away from the operator.

4. Always observe the SAFETY RULES on Page

3 when using the unit.
