Belt tension
Correct belt tension is crucial for minimising belt wear and maximising machine efficiency. The C45 uses a flexible tensioning device
(shown in blue below). The tension of the device is set by adjusting the angle of how much the device flexes.
Note
: New belts can lose tensio
n as they “wear in” and so it is recommended to check the tension after the first 5 hours of oper
ation
on new belts and readjust if necessary.
Checking and setting belt tension
With the engine off, fully
engage the cutting rotor.
Check the angle of the blue
tensioner device. When the
engagement handle is fully
engaged, this should be bent
15°, as shown. The angle can
be checked by placing a ruler
on the square base and
checking that it lines up with
the lower cut-out (not the
upper cut-out) in the metal
plate as shown. This is the
best way to set the angle.
Some machines may not have
this cut-out and instead the
indicator on the tensioner can
be used.
