➤ Checking belt tension with a measuring device or by hand according to the following instruc‐
tions:
Checking belt tension with tension measuring
device
Belt tension checking by hand
Use a measuring device to check belt tension.
1. Check belt tension with the tension measur‐
ing device.
2. Increase the tension on a loose belt.
Press the belts in with the thumb at the mid-
point between pulleys.
1. Check belt tension by hand (see Fig. 73).
2. Increase the tension on a loose belt.
Checking belt tension on the tensioner:
Belt tension can be also checked using the belt tensioner, in alternative to the check directly at the
drive belt.
See chapter 10.7.8.3; Figure 75.
To determine if the belt needs tensioning, the tensioner
6
should be loosened from the tensioning
frame

.
1. Loosen the locking nuts
24
and
8
.
2. Check if there is a gap between the sleeve

and the two adjacent washers and whether the
spherical seat washer
10
and /or washer
20
are present.
Tension the belts if a gap can be seen.
3. Tighten the nut
8
against the tensioning frame
4
and lock with the locknut
