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.
At least once a season, check to see if
you should make any of the adjustments
described in the Service and Adjustments
section of this manual.
• At least once a year, replace the spark
plug and replace air filter element. A
new spark plug and clean/new air filter
element assure proper air-fuel mixture
and help your engine run better and

LUBRICATION
To prolong the useful life of your trimmer,
change engine oil as recommended in this
section of Owner'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.
