After this, remove the screws of the entry chute
(image 1.3). Tilt the entry chute backwards with care
(image 1.4).
The machine could lose its balance. If necessary,
wedge the machine (image 1.5). When the entry chute
is tilted backwards, you can start to remove from the
sides (image 1.6).
Mount the entry chute again following the above steps
backwards.
8.2. REPLACEMENT AND ADJUSTMENT OF THE
BELTS
Before doing any maintenance work or repair work
on the machine make sure that the engine is stopped
and remove the spark plug. Carry out all maintenance
work with the machine on a flat surface and free of
any debris.
Remove the cover that covers the belt. Unscrew
slightly the screw that holds the belt box to the rotor
box (image 2.1).
Loosen a little the screws that hold the chassis to the
engine (image 2.3).
Move the engine block backwards so as to loosen the
belt with the tensing pulley. Remove the belts one by
one and substitute. Place the new belts, in the reverse
way as to that described above. Only use original
parts.
TIP: When you change the belts, it is easy to check the
distance between blades and the counter blade, as
the rotor can turn freely.
Tense the belts by moving the engine block forwards
using the tensing pulley and once you have found the
correct belt tense, block the engine by screwing to the
chassis.
Ensure, once the belts have been tensed, that the
pulleys are properly aligned. Carry out this process
through the use of a ruler. The belts will be properly
tensed when they can be tensed +/- 8cm (2.5
inches_) (image 2.4).
