Mounting and dismounting circular blades
In order to replace a circular blade use wrench no. 17.
For dismounting a circular blade untighten all self-locking nuts (E) and unscrew all bolts (A).
Next remove holding disk (B), and then remove worn circular blade (C) from resistance disk pin
(D) (Fig. 7).
To re-mount clean resistance disk (D) and install a new circular blade (C) onto resistance disk
pin (D). Next put back holding disk (B). Then tighten all bolts (A) through holes in holding disk (B)
and circular blade (C) into resistance disk (E) by tightening them with toque of 49 Nm. After this
tighten self-locking nuts (F) on bolts (A) and apply the torque of 49 Nm.
NOTE!
Bolt connections on the circular blade
must be examined every 5 working
hours.

Checking belt tension
Fig. 8. Checking belt tension
Checking belt tension involves measuring belt strand deflection and should be performed
through inspection openings in the guard, which are plugged with rubber plugs, or upon
dismounting the guard.
In order to check the tension apply a load of 100N ~ 10kg in the belt strand half length L what
gives the deflection value U which should be 1÷5mm (Fig. 8).
