4) OPERATION
Never smoke while filling the gasoline
tank
Pre-start inspections
before each start-up, check the following and, if necessary, perform the
service specified.
CHECK deflector, grasscatcher to make sure they are in proper
l
position and tightened.
CHECK oil level in engine and, if necessary, add oil up to, but not
l
over, full mark.
l CHECK cutting heights and adjust (see paragraph "cutting height
adjustment").
Engine startup
Once the machine has been set up properly, start the engine as follows:
A) Operate the brake handle (4) to enable engine startup.
B) Engine with CHOKE system:
If the model is equipped with an accelerator, when the engine is cold,
position the accelerator lever (3) on START.
Engine with PRIMER system:
Press the fuel-enrichment pump located on carburettor 3 or 4 times.
If the model is equipped with an accelerator position the accelerator
lever (3) on MAX.
C) Start engine:
Grip the starting handle (7) and pull the starter rope gently until you
feel the resistance caused by compression.
Then give the starter rope a sharp tug.
CAUTION: The blade starts turning as soon as the engine is started.
Keep the handle (4) pressed during machine operation. When the handle
is released, the engine stops. For further information and explanations,
read carefully the user instruction manual of the engine. Squeeze adjusting
lever towards wheel and move it to the position desired. Assure pin on
adjusting lever engages notch in housing. Refer to figure for the
approximate cutting height afforded by each of the different positions
Engine stop:
The engine and the blade stop when the handle is released.
CAUTION! The blade will continue turning for max. 3 more
seconds after the engine has been stopped.

5) MOWING PROCEDURE

Cutting height adjustment:
Always stop the engine and wait until the mower blade goes to a comple-
te halt. Squeeze adjusting lever towards wheel and move it to the position
desired. Assure pin on adjusting lever engages notch in housing. Refer to
figure for the approximate cutting height afforded by each of the different
positions.
Mowing procedure:
Vary speed to suit grass conditions. Set the engine speed to the maximum
for tall and thick grass or lower for short and thin grass. On self propelled
models squeeze control bar towards handle to engage the transmission;
to stop forward motion release the control bar. The mower can be hand
pushed with the control released.
Never use the lawn mower without either grasscatcher or deflector.

Mowing tips:

Best results are achieved when no more than 1/3 of the height of the
grass is cut off. The cutting deck should be level under all conditions; if
long grass must be cut, use highest cutting height for first mowing. If you
want the grass shorter, then recut to the lower height. If cut too short, the
grass will expend more energy for development of new leaves and less
for root strengthening and will be more subjected to burning. On the
other hand, if allowed to grow too long, the lower part will be shaded
and will discolor. Dispersed clippings mat to form thatch which prevents
proper growth; to prevent grass disease from thatch, bagging is always
recommended. All HARRY mowers are designed to allow immediate
change of function: cutting and bagging at the same time or cutting only
(this is recommended only when grass is high).
