6.1.1 Setting the cogbelts
The precise alignment of the cogbelt pulleys is
very important to guarantee long life.
To align them:
-
Bring the belt to the desired tension, as de-
scribed above, without tightening the screws
-
Only tighten the screws at the side
The operator is responsible
of making sure no persons or
objects are in the machine's
range of action!
5.5 Safety distances
The following safety distances must be respect-
ed for all forestry tillers/stone crushers
30 m 30 m
15m15m
All maintenance on the ma-
chine must be carried out with
the tool on the ground and the
tractor stopped, removing the
keys from the dashboard.
Interventions must be carried
out in safe conditions, using
appropriate tools and personal
protective equipment.
6. MAINTENANCE
To check the belt tension, use
a belt tension gauge to detect
belt frequency. A digital guitar
tuner which shows the frequen-
cy can also be used instead of
a belt tension gauge. (Smart-
phone)
To adjust the tension of traditional belts, proceed
as follows:
- unscrew the fixing screws and nuts of the belt
protection,
- after having opened the protection, loosen the
screws and nuts securing the extension to the
frame, without removing them,
- stretch the tie rod to reach the correct belt
tension,
- tighten the screws and nuts loosened in point 2,
- close the belt protections
All the operations not de-
scribed in this manual can
only be carried out by qualified
and specifically specialised
personnel.
There are three types of lateral transmission:
V-belts, cogbelts and parallel axis gearboxes.
To adjust tension, strike the middle of the belt
with an object and measure the frequency with a
measuring instrument.
Check belt tension every 50 hours, as indicated in
the diagram below.
