Grillo Climber 910 [15/64] Changing the belts

CAUTION!

Tighten the fixing screw (n.3, Fig. 1/C) firmly.

Always replace damaged or crooked blades; never attempt to repair them! When fitting, always follow the

diagram (Fig. 13).

ALWAYS USE ORIGINAL BLADES! If they are worn they can be turned round since they have two cutting edges.

ADJUSTING THE CUTTING PLATE

Levelness of the cutting plate 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. Adjust the right and left

adjustment devices so that the edge of the cutting plate is at the same distance from the floor, 30 mm,

on both sides (with the operator sitting on board) Fig. 14 - 14/A.

If you are unable to level off the plate, contact an Authorised After-Sales Service Centre.

ENGINE - BLADE BELT

Self-adjusting. No adjustment is required. Simply check the spring tension. (Fig. 15).

If the belt becomes twisted or comes off, check the dimensions stated below, keeping the plate at the

highest setting (“travel”):

1) 170 mm from the edge of the plate to the ground.

2) 170 mm from the rear edge of the plate to the ground.

3) Adjust the registers (Fig. 14 - 14/A).

4) Take care when positioning the belt guides; move them towards the belt, checking the plate at the

various height settings (A, Fig. 12). Check that during operation the belt is always in the centre of the

stretcher (A, Fig. 15).

ENGINE - HYDROSTATIC TRANSMISSION BELT

Whenever there is a change in belt length and subsequent malfunctioning, the tension can be regulated

by means of the adjustment device (Fig. 16). Take care not to compress the spring beneath the unit

completely; belts must be neither too taut nor slack. The spring must be kept set at 44 mm (Fig. 16).

BLADE ROTATION

Rotation is started and stopped using the button 1 Fig. 1.

When rotation is engaged, the engine must be running at medium rpm (see throttle sticker) and the machine must

not be in the grass for cutting. 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!!! When the lever is lowered the blade starts up 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 authorised after-sales service centre.

CHANGING THE BELTS

The movement is transmitted from the motor to the hydraulic transmission and to the blades by means

of two vee-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.

For cutting plate drive belt, the belt guides behind the electromagnetic clutch and beside the plate pulley

have to be removed; release the belt stretcher spring (Fig. 15, B).

For the two transmission and hydraulic motor drive belts proceed as follows:

1) remove the rear and top grille

2) undo the belt stretcher nut and remove the clutch belt guide.

ALWAYS USE ORIGINAL BELTS!

TRACTION RELEASE LEVER

The traction release device is located behind the seat; if the machine breaks down, to allow it to be towed or moved by

hand, move the lever outward (fig. 20/A). In the position shown in fig. 20/B the machine is in working condition. Check

that during operation the hydraulic motor piston does not remain pressed down; if necessary, adjust the nut (fig. 20/C).
