Changing The Belts - Grillo CLIMBER 9.18 Manual De Instrucciones

Climber 9.22/ Translation of the original instructions
ENGINE BELT - CUTTING DECK BELT
The engine – blade belt is self-adjusting. Therefore no adjustment is required. Simply check the spring
tension (fig. 15). If the belt becomes twisted or comes off, check the parameters below, keeping the
cutter deck in the highest position ("transfer" position):
1) 170 mm from the edge of the deck to the ground (fig. 24).
2) 170 mm from the rear edge of the deck to the ground (fig. 24).
3) Adjust the registers (fig. 14 – 14A).
4) Take care when positioning the belt guides; move them towards the belt, checking the cutter deck at
the various height settings (fig. 12, ref. A). Check that during operation the belt is always in the centre of
the stretcher (fig. 15, ref. A). The stretcher has to stick about 5/8 mm out of the frame (fig. 25).
ENGINE – HYDROSTATIC TRANSMISSION BELT
Whenever there is a change in belt length (causing therefore its 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 tight nor loosen. The spring must be kept set at 44 mm and it is
indicated by the red arrow (fig. 16)
BLADE ROTATION
Rotation is started and stopped using the switch (no. 1, fig. 1). When rotation is engaged the engine
must be running at medium rpm (see label on the throttle lever) and the machine must be outside 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 (fig. 1, no. 1), the blades do not start automatically. To start the
blade the PTO button must be switched off and switched on again (fig. 1, no. 1). The blade must stop
within 5 seconds when the PTO button is switched off and when the operator leaves the driver's seat. 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. IMPORTANT: 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. For the cutter deck – engine belt, the belt guides of the deck pulley have to be
removed; release the belt stretcher spring (fig. 15, ref. B). For the two transmission and hydraulic engine
belts proceeds as follows:
-remove the rear and top grids
-undo the belt stretcher nut (fig. 16)
ALWAYS USE ORIGINAL BELTS!
TRACTION RELEASE LEVER
The traction release device is located behind the seat; in case of emergency, to allow it to be towed or
moved by hand, move the lever outward (fig. 20A). In the position shown (fig. 20B) the machine is in
working condition. Check that during working the hydraulic engine piston does not remain pressed down;
if necessary, adjust the nut (fig. 21).
DIFFERENTIAL LOCK ADJUSTMENT
The differential lock has to be activated when the pedal is half way of its travel (fig. 8). To adjust the
activation point of the differential lock use the screw (fig. 9).
