MAINTENANCE & ADJUSTMENTS
Safety Precautions
l
Make sure the engine is off before you begin any maintenance or repairs. This
will eliminate several potential hazards:

- Carbon monoxide poisoning from engine exhaust.

Be sure there is
adequate ventilation whenever you operate the engine.

- Burns from hot parts.

Let the engine and exhaust system cool before
touching.

- Injury from moving parts.

Do not run the engine unless instructed to do so.
l
Read the instructions before you begin, and make sure you have the tools and
skills required.
l
To reduce the possibility of fire or explosion, be careful when working around
gasoline. Use only a nonflammable solvent, not gasoline, to clean parts. Keep
cigarettes, sparks, and flames away from all fuel-related parts.
l
For certain operations, the mower must be raised off the ground. Be sure the
mower is solidly supported before you put any part of your body under it.
l
Wear heavy gloves when near the mower deck, belts, or blades.
Remember that your authorized Honda servicing dealer knows your mower best
and is fully equipped to maintain and repair it.
To ensure the best quality and reliability, use only new, genuine Honda parts or
their equivalents for repair and replacement.
EMISSION CONTROL SYSTEM INFORMATION Source of Emissions
The combustion process produces carbon monoxide, oxides of nitrogen, and
hydrocarbons. Control of hydrocarbons and oxides of nitrogen is very important
because, under certain conditions, they react to form photochemical smog when
subjected to sunlight. Carbon monoxide does not react in the same way, but it is
toxic.
Honda utilizes lean carburetor settings and other systems to reduce the emissions
of carbon monoxide, oxides of nitrogen, and hydrocarbons.
The U.S and California Clean Air Acts
EPA and California regulations require all manufacturers to furnish written
instructions describing the operation and maintenance of emission control
systems.
The following instructions and procedures must be followed in order to keep the
emissions from your Honda engine within the emission standards.
