plug wrench, tighten it an additional 1/8 to 1/4 turn so that the
washer is correctly compressed.
3. Put the throttle lever in the FAST position and repeat step 3 ~ 6
under STARTING THE ENGINE (page 9).
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 blades rotate 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.
Blade Control Lever
To start blade rotation,
press the yellow button [1]
on top of the blade control
lever [2], then push the
lever forward and hold it
against the handlebar.
Release the blade control
lever [2] to stop the blade.
Operate the blade control
lever with a quick and
complete motion, so the
blade control is always
either fully engaged or
disengaged. This will help
to prevent stalling the
engine, and it will help
prevent damage to the blade control mechanism.
Drive Clutch Lever
Push the drive clutch lever [1] forward to propel the mower forward.
For self-propelled mowing, press the yellow button [2] on top of the
blade control lever [3], push the blade control lever forward to the
handlebar, then push the drive clutch lever [1] forward.
Release the drive clutch lever [1] to stop the mower's forward
movement.

ENGLISH

You can control mower speed with the drive clutch lever [1]. The
mower will move gradually faster as you push the lever forward. If you
push the lever all the way up to the handlebar, the mower will move at
the speed determined by the shift lever setting.
Shift Lever
Use the shift lever [1] to select
the forward speed at which
you wish to mow.
Do not use the throttle lever to
adjust your forward speed.
The throttle lever must remain
in the fast position for good
mowing performance.
Otherwise, cut quality suffers.
Use the lower speed range for
mulching and bagging, the
higher speed range for
transporting.
With the shift lever all the way back and the drive clutch lever
engaged, the mower will move slowly or not at all.
