High Altitude Operation
At high altitude, the standard carburetor air-fuel mixture will be too
rich. Performance will decrease, and fuel consumption will increase. A
very rich mixture will also foul the spark plug and cause hard starting.
High altitude performance can be improved by specific modifications
to the carburetor. If you always operate your mower at altitudes above
1,500 meters, have a Honda dealer perform this carburetor
modification.
Even with carburetor modification, engine power will decrease about
3.5% for each 300 meter increase in altitude. The effect of altitude on
power will be greater than this if no carburetor modification is made.
NOTICE
When the carburetor has been modified for high altitude operation,
the air-fuel mixture will be too lean for low altitude use. Operation at
altitudes below 1,500 meters with a modified carburetor may cause
the engine to overheat and result in serious engine damage. For use
at low altitudes, have your authorized Honda dealer return the
carburetor to original factory specifications.
OPERATING THE CONTROLS FOR MOWING
Throttle Lever
For best cut quality, always mow with
the throttle lever [1] in the FAST
position [2]. When the blade rotates at
the preset fast speed, it creates a
strong fan action that lifts and cuts
grass more efficiently.
Do not try to increase the preset engine
speed; the blade could fracture and
come apart.
Flywheel Brake Lever
The flywheel brake lever [1]
must be pulled back against
the handlebar to start the
engine. The blade starts to
rotate when the lever is
pulled back against the
handlebar and the recoil
starter grip is pulled.
Continue to hold the lever
against the handlebar to
keep the engine running and
the blade rotating.
Release the lever to stop the engine and stop blade rotation.

Drive Clutch Lever
Push the drive clutch lever [2]
forward and hold it against
the handlebar to propel the
mower forward.
Release the drive clutch lever
to stop the mower's forward
movement.
Always release the drive
clutch lever before starting
the engine. If the drive clutch
is engaged, the mower will
move forward when you
operate the starter.
Operate the drive clutch lever
with a quick and complete
motion, so the drive clutch is
either fully engaged or
released. This will help to
extend the service life of the
clutch mechanism.
STOPPING THE ENGINE
1. Move the throttle lever [1] to the
SLOW [2] position.
2. Release the drive clutch lever [4]
and the flywheel brake lever [3]
to stop the engine.
3. When the mower is not in use,
turn the fuel valve [5] to the
OFF [6] position.
