Lengthening Cutting Line

1. To lengthen line, tap spool on the ground while the motor
continues to run (Fig. 6); do not hold it on the ground. The
cutting knife attached to the shield will cut the line to the
proper length.
Note: To help prevent line tangle, tap only once to lengthen line. If
additional line is required, wait a few seconds before retapping
trimmer head. Do not allow line to wear too short. Keep line length
at full cutting diameter as much as possible.

Replacing Cutting Line

For best performance, use only Toro spools. Prewound
replacement spools can be purchased from your local Toro retailer.
