EMAK efco BLE 506 Betribs- Und Wartungsanleitung Seite 150

Le plateau de coupe est équipé de caches en plastique qui empêchent les mains d'accéder aux pièces mobiles et aux
pièces de la transmission de la machine.
Les caches peuvent être retirés rapidement et facilement à l'aide des goupilles de fixation rapide sur les côtés des
caches. Glissez un tournevis dans l'encoche de la goupille et tournez-le dans le sens inverse des aiguilles d'une montre.
Retirez ensuite le cache de la machine.
Machines 106, 106 4x4 et 124 :
► Distance A is the front edge of the mowing deck in the travel direction and it must be 23-25 mm above the ground.
Check it on both sides of the mowing deck. If the height is different, loosen the lock nuts (2) on the respective draw
rod (1) and adjust the height by the turning nuts (3). After setting the correct height, do not forget to tighten the lock
nuts (2).
6.3.7a
► Distance B is the rear edge of the mowing deck in the travel direction and it should be 28-30 mm above the ground,
i.e. the rear edge must be at least 5 mm higher than the front edge. If the height is different, adjust it by loosening
nuts (4), setting the edge to the correct height and tightening the nuts with a torque of 55 – 65 Nm.
Machines 110 :
► Distance A is the front edge of the mowing deck in the travel direction and it must be 30-34 mm above the ground.
Check it on both sides of the mowing deck. If the height is different, loosen the lock nuts (2) on the respective draw
rod (1) and adjust the height by the turning nuts (3). After setting the correct height, do not forget to tighten the lock
nuts (2).
6.3.7b
► Distance B is the rear edge of the mowing deck in the travel direction and it should be 28-30 mm above the ground,
i.e. the rear edge must be at least 5 mm higher than the front edge. If the height is different, adjust it by loosening
nuts (4), setting the edge to the correct height and tightening the nuts with a torque of 55 – 65 Nm.
En cas de doute sur cette procédure, faites effectuer l'opération par un centre de service.
6.3.8 PLATEAU DE COUPE - VÉRIFICATION ET RÉGLAGE DE LA COURROIE EN V
En raison des contraintes qu'elle subit, la tension de la courroie d'entraînement du plateau de coupe (1) diminue au fil
du temps et il est nécessaire de la retendre. La courroie est tendue grâce à des boulons et un ressort.
► Set the mowing deck to position 1.
► Using a suitable wrench, turn nut (2) so that spring (3) is tensioned to a value of :

6.3.9 PLATEAU DE COUPE - RÉGLAGE DE LA COURROIE D'ENTRAÎNEMENT DE LA LAME DENTELÉE
Machines 106, 106 4x4 et 124 :
► Lower the mowing deck to the lowest position by moving the height adjustment lever to position 1.
► Release the quick coupling pins of the mowing deck side covers and take the covers out.
6.3.9a
► Release the quick coupling pin (1) of the top cover (2) and approximately in its middle tilt the cover upwards.
► Slide an appropriate spanner under the metal cover, from underneath place it on the belt pulley bolt (1). From above
loosen the belt pulley nut.
► Loosen the lock nut (2) and nut (3). Then, using an appropriate wrench, turn nut (3) so that the cogged belt (4) is
6.3.9b
properly tensioned.
► The belt is correctly tensioned when a force of 4 kP (40 N; 72 Hz) acting on the middle distance between the belt
pulleys (1) and (5) results in the belt bending by approximately 0,5 cm.
6.3.9c
Pour mesurer la force, il est possible d'utiliser un dynamomètre mécanique standard, disponible dans les magasins spécialisés.
► Tighten the lock nut (2) of the tensioning mechanism and again tighten the nut of the cogged belt pulley (1).
► Reattach the side and top cover and tighten them.
Machines 110 :
► The mowing deck drive belt is correctly tensioned when the length of the tensioning spring (2) is 135±1 mm. If the
length is different, adjust it by turning nut (1) of the tensioning draw bar.
6.3.9d
6.3.10 PLATEAU DE COUPE - LE RETIRER DE LA MACHINE
► Set the mowing deck to the highest position by moving the elevation adjustment lever to position 7.
► Slightly lift up the grass ejection chute (1) and slide it off the two pins welded to the frame of the mowing deck. Then
6.3.10a
either move the chute approx. 10 cm backwards and secure it in place, or completely take it out through the rear plate.
