MAINTENANCE

GENERAL RECOMMENDATIONS

The warranty on this trimmer does not cover items that have been subjected to operator abuse or negligence. To receive full value from the warranty, operator must maintain trimmer as instructed in this manual.

Some adjustments will need to be made periodically to properly maintain your unit. All adjustments in the Service and Adjust- ments section of this manual should be checked at least once each season.

Once a year, replace the spark plug and replace air fi lter element. A new spark plug and clean/new air fi lter element assure proper air-fuel mixture and help your engine run better and last longer.

Follow the maintenance schedule in this manual.

BEFORE EACH USE

1.Check engine oil level.

2.Check for loose fasteners.

3.Clean under engine cover.

LUBRICATION

To prolong the useful life of your trimmer, change engine oil as recommended in this section of Operator’s Manual. IMPORTANT: Do not oil or grease plastic wheel bearings. Viscous lubricants will attract dust and dirt that will shorten the life of the self- lubricating bearings. If you feel they must be lubricated, use only

a dry, powdered graphite type lubricant sparingly.
