OPERATING HINTS AND TIPS

USING THE LAWNMOWER AT HIGH ALTITUDES
At high altitudes, the standard gas/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 carburetor with a smaller diameter jet and by adjusting
the pilot screw. If you use your lawnmower at an altitude of more
than 1 800 metres above sea level, we recommend that you have
these modifications made by your authorized Honda dealer. Even
with the appropriate modifications made to the carburetor, engine
power will be reduced by about 3.5 % for every 300 metres of
altitude. However, the altitude will have a much greater effect on
power if these modifications are not carried out.
CAUTION:
• Running the lawnmower 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 lawnmower may tip over and cutting means may throw out
objects which were hidden.
Keep the 4 wheels firmly on the ground.
Control the direction of the lawnmower using the handle and
not by exerting pressure on the cutting-means housing with
your foot.
CAUTION:
• When mowing around an obstacle, be careful that the cutting means
does not hit it. Never push the lawnmower directly over an object.
• When mowing an uneven area, do not let yourself be pulled along by
the lawnmower. Hold the handle firmly and control its advance.

NOTE: If the lawnmower speed is too low when cutting on a slope,
move the shift lever slightly towards the "FAST" position.
CONTROLS AND MOWING
PROCEDURES
Read the safety instructions before
SAFETY
starting to mow.
To mow:
1. Place the lawnmower in an
obstacle free area.
2. Start the engine, allow it to reach
its maximum temperature and
rotation speed. (The engine runs
evenly when the throttle control
lever is moved away from the
"CHOKE" position).
3. Select the required forward speed using the shift lever [3]
(except type QXEH).

4. Engage the cutting means:
press the yellow button [4]
situated on the top of the
cutting-means control
lever [5].
CAUTION:
• Move the cutting-means
control lever [5] quickly
and completely. so that the
clutch is always totally
engaged or disengaged.
The purpose of this is to avoid stalling the engine and prolongs
the lifetime of the cutting-means control mechanism. Always
release the cutting-means control lever and the drive clutch
before starting the engine. When the cutting- means drive is
engaged, starting is not as easy. If the drive clutch is engaged, the
lawnmower moves when started.
5. Wait for the engine to get up to speed before starting cutting.
6. To cut in self propulsion, push the drive clutch lever [7] against
the handle and hold it there.
NOTE: The drive clutch lever acts as a variable speed unit
according to its position. It can vary the speed between zero and the
maximum speed preselected with the shift lever. The maximum
speed is reached when the shift lever is put on the maximum speed
and the clutch lever is held against the handle.
CAUTION:
• Move the lever quickly from one end of its travel to the other, so that
the clutch is always either fully engaged or fully disengaged. This
avoids stalling the engine and increases the service life of the clutch
mechanism.
7. To stop the lawnmower moving,
release the clutch lever [7].
8. To stop the cutting means
rotating, release the cutting-
means control lever [6].
NOTE:
• Mowing frequency: once a week
for a lawn intended for leisure
purposes, twice a week for an
ornamental lawn.
• If possible, mow the lawn in the
afternoon or evening before
sprinkling, as the grass must be
dry. If dust levels are too high,
mow the lawn when the grass is
dry, but the ground is still damp.
• Choose a cutting height adapted
to the terrain (see page 6).
• For a regular cut, you should
overlap the part that has already
been cut by a few centimetres [8],
and increase this overlap zone if
the cutting height is high.
To achieve maximum efficiency,
follow the suggested path.
