OPERATING INSTRUCTIONS

TIPS FOR BEST TRIMMING RESULTS

• Keep the cutting attachment parallel to the ground.

• Do not force the cutting attachment. Allow the tip of

the line to do the cutting, especially along walls.

Cutting with more than the tip will reduce cutting effi-

ciency and may overload the engine.

• Cut grass over 8 in. (200 mm.) by working from top

to bottom in small increments to avoid premature

line wear or engine drag.

• Cut from left to right whenever possible. Cutting to

the right improves the unit's cutting efficiency.

Clippings are thrown away from the operator.

• Slowly move the trimmer into and out of the cutting

area at the desired height. Move either in a forward-

backward or side-to-side motion. Cutting shorter

lengths produces the best results.

• Trim only when grass and weeds are dry.

• The life of your cutting line is dependent upon;

• Following the previous trimming techniques

• What vegetation is being cut

• Where it’s being cut

NOTE: Some maintenance procedures may require

special tools or skills. If you are unsure about

these procedures take your unit to an authorized

service dealer.

MAINTENANCE SCHEDULE

These required maintenance procedures should be

performed at the frequency stated in the table. They

should also be included as part of any seasonal tune-up.

WARNING: To prevent serious injury, never

do maintenance or repairs with unit running.

Always do maintenance and repairs on a cool

unit. Disconnect spark plug wire to ensure

the unit will not start.

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 accomplished by removing all

vegetation around trees, posts, fences, etc.

Rotate the whole unit so that the cutting attachment is at

a 30° angle to the ground (Fig. 10).
