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
Adjustments section of this manual should
be checked at least once each season.
• Once a year, replace the spark plug
and replace air filter element. A new
spark plug and clean/new air filter
element assures proper air-fuel
mixture and helps 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 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.
