Important - Grillo CLIMBER 10 AWD 22 Manuel D'utilisation

CHECKING BLADES AND CUTTING DECK
A blunt blade tears the grass, leaving it unattractive. The cutting edges of both blades must always be
well-sharpened. To remove a blade, take hold of it firmly, wearing working gloves, and unscrew the
central screw. IMPORTANT: the screw has a right-hand thread. Sharpen both cutting edges using a
medium-grain grinding wheel and check that the blade is balanced by placing it on a round bar
inserted in the central hole. Fit the two cutting blades following the diagram (fig. 6).
IMPORTANT: Tighten the fixing screw firmly. Always replace damaged or crooked blades, never
attempt to repair them! USE GENUINE BLADES ONLY! If they are worn they can be turned round
since they have two cutting edges.
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 first that the tyre pressure is correct, then use the left and right adjusting
screws (fig. 18) and those of the front cutting deck arms (fig. 19) to set the cutting deck at 210 mm
from the ground (fig. 22 – fig. 23) on both sides, with the operator on board and the cutting deck at the
highest cutting position. In case of need contact the nearest authorised service centre. For the
Climber 10 AWD 27 a baffle (fig. 20) is delivered standard, which can be fixed under the cutting deck
on the right side. It is used to disperse cut grass evenly and it has to be used with 12/15 cm grass
only.
BLADE – ENGINE BELT
The engine – blade belt is self-adjusting and it is a special B-type belt. It is sufficient to check the
spring tension (fig. 25). If the belt twists or comes out of its position, carry out the following controls
setting the cutting deck at the highest cutting position:
1) check that the distance between the front boarder of the cutting deck and the ground is 210
mm (fig. 22).
2) check that the distance between the rear boarder of the cutting deck and the ground is 210
mm (fig. 23).
3) Use the adjusting screws (fig. 18 – fig. 19).
4) IMPORTANT: beside the cutting deck pulley there is a belt guide equipped with bearings (fig.
24) that prevent the belt from going out of its position should this oscillate. This belt guide must not
continuously touch the belt. The belt guide is fixed and the cutting deck has to be set perfectly parallel
to the ground or slightly inclined to the front.
5) To replace the belt unhook the spring of the belt tightener (fig. 25) and shift the belt guide (fig.
24) to let the belt come out from the deck pulley.
6) Grease the belt tightener (fig. 21).
ENGINE BELT – HYDROSTATIC AXLE
This belt is self-adjusting through a spring. To replace the belt detach the spring of the cutting deck
belt tightener (fig. 25) and the clutch belt. In addition remove the rear right wheel and its bumper.
Detach the anti-vibration spring connected with the clutch (fig. 26). Then detach the belt tightener
spring of the hydrostatic transmission (fig. 27). The belt can then be removed. USE GENUINE BELTS
ONLY.
BLADE ROTATION
To engage and disengage the blade push the button on the dashboard (fig. 1, n. 6). When rotation is
engaged the engine must be running at medium r.p.m. (see throttle label) and the machine must be
placed outside to area to be cut. Never start the blades with the engine at maximum r.p.m. The
machine is equipped with an electromagnetic clutch which also brakes the blade during
disengagement. The blade must stop within 5 seconds with the engine at max. r.p.m. Should this not
be the case, remove the spacer mounted under the brake of the blade brake (fig. 28). IMPORTANT:
This operation must be carried out by an authorized service center. Do not use the machine if
the blade does not stop within 5 seconds after disengagement with the engine at max. r.p.m.
