screw, remembering that the screw has a right-hand thread (3 fig. 8). Sharpen both cutting edges
using a medium-grain grinding wheel and check that the blade is balanced by standing it on a round
bar inserted in the central hole. Fit the two cutting blades following the diagram (fig. 8).
CAUTION!
Tighten the fixing screw (3 fig. 8) firmly. Always replace damaged or crooked blades; never attempt to
repair them! When fitting, always follow the diagram (fig. 8). ALWAYS USE ORIGINAL BLADES! If
they are worn they can be turned round since they have two cutting edges. Always check that the
blade bolts are not worn or damaged.

ADJUSTING THE CUTTING DECK

Levelness of the cutting deck is essential in order to obtain an evenly mown lawn. Park the mower on
a flat surface and check that the tyre pressure is correct. Use the 4 adjustment devices (fig. 17 –
17A), so that the edge of the cutting plate is at the same distance from the floor (100 mm) on both
sides (with the operator sitting on board and the cutting deck in the position no. 1. If you are unable to
level off the deck, contact an authorised After-Sales Service Centre.
BLADE – ENGINE BELT
Make all the checks and adjustments (fig. 16), keeping the deck at the lowest position.
Take care when positioning the belt guides; move them towards the belt, checking the deck at the
various height settings. Check the belt tensioner spring (fig. 18).
HYDROSTATIC AXLE – ENGINE BELTS
These belts are self-adjusting and do not require any adjustment. Simply check the spring tension.
To replace the belts, release the tension spring (fig. 19).
BLADE ROTATION
Rotation is started and stopped using the switch (no. 6, fig. 1).
When rotation is engaged the engine must be running at medium rpm (see indication on the
accelerator decal) and the machine must not be in the area to be cut. Never start the blades with the
engine at maximum rpm. The machine is equipped with an electromagnetic clutch which also brakes
the blade during disengagement. The blades are also disengaged automatically when the cutting
height adjuster lever is moved to the highest position.
CAUTION: for safety reasons if the operator pushes down the height adjustment lever from the
highest position with the PTO button engaged, the blades do not start automatically. To start the
blade the PTO button must be switched off and switched on again.
The blade must stop within 5 seconds. If this is not the case, adjust the 3 nuts of the electromagnetic
clutch, placing a 0.3 mm feeler gauge under the brake plate. N.B. This operation must be carried
out by an authorized after-sales service center.

CHANGING THE BELTS

The movement is transmitted from the motor to the hydraulic transmission and to the blades by
means of two V-belts. Replace the belts as soon as they show signs of wear! Their replacement
and subsequent adjustment are fairly complex procedures and must be carried out by an Authorised
After-Sales Service Centre. To change the cutting deck drive belt remove the belt guide beside the
deck pulley (fig. 17) and release the belt stretcher spring (Fig.19).
ALWAYS USE ORIGINAL BELTS!
TRACTION RELEASE LEVER
The traction release lever is located at the back of the machine (fig. 20). If the machine breaks down,
move the lever to idle position to allow it to be towed or moved by hand (B, fig. 20). In the position (A)
the machine is in working condition.
