Unscrew the bolts (Fig. 7.4) of the top cover (Fig. 5.1 47) and take it away (Fig. 7.5).Check the tension of the belts (Fig.
7.6). If the belts are damages or broken; see next chapter “Replacing the Belts” how to replace them.
The Static Belt Tension should be 250 N with a new belt, only 200 N with a used one. It is recommended to use an
OPTIKRIK 1 Tension Gauge (Fig. 7.6).
To change the Static Belt Tension, lose the 4 bolts on the motor base (Fig. 5.1 50) (Fig. 7.7). Unsecure the two nuts of
the tensioner (Fig. 7.8, Fig. 7.9) Tension by moving the motor closer or wider.
After tensioning secure back the nuts on the tensioner device (Fig. 7.10). When mounting back the top cover (Fig. 5.1
47), see to it the sealer is still in place (Fig. 7.11).
REPLACING THE BELTS
Open the tension device totally (Fig. 7.13). Open up the bottom cover (Fig. 5.1 22) (Fig. 7.14). Remove the belts (Fig.
7.15).
