THE IMPORTANCE OF MAINTENANCE
Good maintenance is essential for safe, economical, and trouble-free
operation. It will also help reduce air pollution.
Improper maintenance, or failure to correct a
problem before operation, can cause a
malfunction in which you can be seriously
hurt or killed.
Always follow the inspection and maintenance
recommendations and schedules in this
owner's manual.
To help you properly care for your mower, the following pages include
a maintenance schedule, routine inspection procedures, and simple
maintenance procedures using basic hand tools. Other service tasks
that are more difficult, or require special tools, are best handled by
professionals and are normally performed by a Honda technician or
other qualified mechanic,
The maintenance schedule applies to normal operating conditions. If
you operate your mower under severe conditions, such as sustained
high-load or high-temperature operation, or use in unusually wet or
dusty conditions, consult your servicing dealer for recommendations
applicable to your individual needs and use.
Maintenance, replacement, or repair of the emission control
devices and systems may be performed by any engine repair
establishment or individual, using parts that are "certified" to
EPA standards.
