Section 4 - MAINTENANCE
4.1 INTRODUCTION
To retain the quality of the SNAPPER mower, use
genuine SNAPPER replacement parts only. Contact
a local SNAPPER dealer for parts and service
assistance. For the correct part or information for a
particular 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 nearest SNAPPER dealer in your
area, check the yellow pages under the heading
LAWN MOWERS. For engine parts and service,
look for the engine manufacturer’s dealers under the
heading, ENGINES - gasoline.
