Maintenance

Maintenance, replacement or repair of emission control
devices and systems may be performed by any repair
establishment or individual; however, warranty repairs
must be performed by a dealer or service center autho-
rized by MARUYAMA Manufacturing Company, Inc.

and durability to authorized parts may impair the effec-

bearing on the outcome of a warranty claim.
Maintenance on today's low-emission engines is
even more critical for longest life and best perfor-
mance. particularly critical are air and fuel filters,
spark plug heat range, cooling air intake area and
proper gaps of coil and plug.
