SHARPENING AND REPLACING THE BLADE
!
WARNING! Each operation indicated
below must be carried out while the engine
is off, the blade stopped, the spark plug cap
disconnected and the fuel tank empty. Always
wear protective gloves.
!
WARNING! The assembly of the blade
must be carried out with absolute precision.
Incorrect assembly causes danger.
If you have to replace the blade because of its
poor condition, only use original spare parts of
equal size and shape.
Before you start, carefully study the components
and figure M. If you are not familiar with handling
and assembling mechanical components, we
recommend that you contact an authorised
service centre.
Avoid turning the blade by hand as it is directly
connected to the piston and may compress the
engine combustion chamber.
1. Wear protective gloves.
2. Fig. M1: Disconnect the spark plug cap (pos.
16) from the spark plug (pos. 15) to prevent
suddenly starting the machine, and empty
the tank.
4. Fig. M2: Tilt the lawnmower as shown in the
figure to gain access under the machine (tank
cap and carburettor will be in the upper part).
Secure the position with straps to prevent the
machine from falling on you.
5. Fig. M3: Use one hand to hold the blade (pos.
22) away from the cutting area, and using a
socket hex key, unscrew the screw (pos. 23).
Remove the washer (pos. 24) and remove
the blade.
6. Fig. M4: Sharpen the two cutting edges of the
blade, while retaining the cutting angle.
7. Fig. M5: Check the balancing of the blade; if
necessary, sharpen one of the cutting edges
more in order to counterbalance.
8. Fig. M6: Reinstall the blade on the end of the
engine shaft (pay attention to the positioning
pins and the respective holes on the blade);
the cutting edge must face the soil. Insert the
washer and tighten the screw with a tightening
torque of 30 Nm.
9. Visually check that the blade is correctly
assembled.
10. Return the lawnmower to a horizontal posi-
tion and start the engine to carry out a dry test
run for 30 seconds.
STORAGE
Clean the machine and all its accessories
thoroughly (see Maintenance section). Protect
unpainted parts with protective oil and use ori-
ginal packaging to protect the machine.
Store the machine in a stable and safe position
out of children’s reach. The place must be dry,
free from dust, temperate and protected from
direct sunlight.
Keep children and unauthorised personnel out
of the storage room.
!
WARNING! Hot surfaces. Some parts of
the machine may stay hot for several hours
after it has been switched off. Wait for it to
cool down completely before storing it.
1. Remove all the fuel from the tank.
2. Pour a few drops of engine oil into the spark
plug hole, put back the spark plug and put
the engine in the compression stroke (slowly
operate the recoil starter lever).
