OPERATING INSTRUCTIONS

ADJUSTING THE TRIMMER LINE

While the unit is operating, the trimming line gets worn down and becomes shorter. This unit is equipped with an Automatic Line

Advancement cutting head which automatically feeds additional line to the correct length as it wears down. If the line does not

automatically advance, the trimming line may be tangled or empty. Refer to the maintenance section of this manual.

The life of your cutting line is dependent upon:

• Following the trimming techniques previously explained

• What vegetation is cut

• Where the 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 the act of removing all vegetation from around trees,

posts, fences, etc. To accomplish it, rotate the whole unit so that the cutting

attachment is at a 30˚ angle to the ground (Fig. 13).

unit, stop the motor, wait for all moving parts to stop and

the line into the hole at the top of the inner reel (Fig. 16).

5. Wind the line, in even and tight layers, onto the reel (Fig. 16). Wind the line in

the direction indicated on the inner reel.

NOTE:
