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

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

turer's dealers under the heading, ENGINES - gaso-
