GENERAL RECOMMENDATIONS

The warranty on this unit does not cover items that have been subjected to operator abuse or negligence. To receive full value from the warranty, the operator must main- tain unit as instructed in this manual. Various adjustments will need to be made periodical- ly to properly maintain your unit.

SOnce a year, replace the spark plug, air filter, and check guide bar and chain for wear. A new spark plug and air filter assures proper air-fuel mixture and helps your engine run better and last longer.

CHECK FOR DAMAGED OR WORN PARTS
