4.1INTRODUCTION

To retain the quality of the SNAPPER mower, use gen- uine SNAPPER replacement parts only. Contact a local SNAPPER dealer for parts and service assis- tance. For the correct part or information for a particu- lar SNAPPER mower, always mention the model and serial number. SNAPPER recommends returning the mower to an authorized SNAPPER dealer annually for inspection and addition of any new devices, which might upgrade the safety of the mower. For the near- est SNAPPER dealer in your area, check the yellow pages under the heading LAWN MOWERS. For engine parts and service, look for the engine manufac- turer's dealers under the heading, ENGINES - gaso- line.
