position [A]), set the throttle lever to "FAST" position [B].
NOTE: To adjust the engine speed when the mower is running, the
throttle lever can be set anywhere between the "FAST" [B] and
"SLOW" [C] positions. However, the best results are obtained in
the "FAST" position [B].
The engine may stall if the lever is in the "SLOW"
position [C] when the blade clutch is engaged.
To facilitate starting, place the mower on a flat surface
where the grass is not long.

2. Remove and dry the spark plug. When refitting the spark plug,
screw it up until it is finger tight and correctly seated. Then using
the plug spanner, tighten it an additional 1/8 to 1/4 turn so that
the washer is correctly compressed.
3. Next, place the throttle lever in "FAST" position [B] and repeat
the operations previously mentionned under the heading

OPERATING HINTS AND TIPS

USING THE MOWER AT HIGH ALTITUDES
At high altitudes, the standard fuel/air mixture in the carburetor is
much too rich: this will reduce performance and increase fuel
consumption.
It is possible to improve the high altitude performance by fitting the
[2]
carburetor with a smaller diameter jet and by adjusting the pilot
screw. If you use your mower at an altitude of more than 1500
meters above sea level, we recommend that you have these
modifications made by your approved Honda dealer.
Even with the appropriate modifications made to the carburetor,
engine power will be reduced by about 3.5% for every 300 meters
of altitude. However, the altitude will have a much greater effect on
power if these modifications are not carried out.
CAUTION:
• Running the mower at an altitude less than that for which the
carburetor is adjusted may cause overheating and seriously
damage the engine, due to the gas/air mixture being far too
weak.
Take special care when mowing on uneven or irregular ground.
The mower may tip over, thus uncovering the blade; also, the
blade may throw out objects which were previously hidden.
Keep the four wheels firmly on the ground.
Control the direction of the mower using the handle and not by
exercing pressure on the blade casing with your foot.
CAUTION:
• When mowing around an obstacle, be careful that the blade does
not hit it. Never push the mower directly over an object.
• When mowing an uneven area, do not let yourself be pulled along
by the mower. Hold the handle firmly and control its advance.
