OPERATION
CAUTION
Check the tightening of bolts, refering to the tightening torque chart
The safety is one of our main worry when designing and manufacturing this machine. Therefore,
negligence in the use of the machine should reduce our efforts to nothing. The prevention strictly
depends on the care and on the skill of the user when applying and maintaining the machine.The
best safety method remains a careful and skilled user ; we wish you to be this kind of user.
The user of this machine is responsible for its safe use. He must be a skilled user specially trained for
the use of this machine. Read the safety instructions. This machine has been designed to mow grass.
It is not designed for any other operation. It is not designed to transport other tools or materials that
might damage it and cause injuries to the user. It must not be used to carry persons.
DANGER
Never use the machine without having priorly carried out all the maintenance operations as
described in the daily maintenance chapter.
CAUTION
Never let children or unskilled persons use the machine. Check that nobody or no object
stands near the machine when at work. They could be hit by the moving parts.Nobody must
stand on the machine except the driver. Never put your hands under moving parts.
STARTING OF THE ENGINE
Turn the fuel cock to "ON".
Check that cutting blade is disengaged, and Driving lever range is in neutral position « N ».
Pull choke lever if engine is cold or push throttle lever half of his stroke if the engine is hot. Pull the
starter rope. When the engine has started, push back the choke lever.
Select a speed ratio and travel to the mowing path.
MOWING
Start the engine
Adjust the height of cut as needed.
WARNING
Do not forget that it is better to mow a few grass often than an important quantity in one
operation. Short grass do not resist to dry weather, and the blade can hit the grown with
damage and thrown objects. Working in slopes is very dangerous. Never work in slopes more
than 15°.
Increase engine speed to the maximum. Push down the blade
clutch lever (2, Figure 8) then engage the blade tension lever
(3, Figure 8) slowly. Then go forward in the grass to mow.
The best cutting speed depends of quantity and the density of
the grass. Usually it is asked to mow between 2,5 and 6 Km/H.
A tall grass will be cut slowly and a low grass will be cut faster.
Figure 8

CAUTION
Clear the mowing path from foreign objects, stones, woods, cans, bottles, pieces of steel,
which can be thrown by the mower. They can cause injury to the operator or the bystanders.
HOW TO STOP THE MACHINE
Release drive clutch lever and blade clutch lever.
Push the throttle lever to “LO”.
Switch the engine stop on “off”
Close the fuel cock
Remove the spark plug wire
CAUTION
Never park the machine on slopes. Stop it on a level and flat surface.
STORING THE MACHINE
Thoroughly clean the machine. Use touch up paint to prevent rust. Check for worn and damage parts,
install new parts as required. Perform the normal maintenance of the machine according to
maintenance chart. Store the machine in a dry protected area. Remove sparking ignition wire from
the sparking plug.
TRANSPORT
Check that the cutting rotor is disengaged.
Check that the spark plug cover is disconnected.
