DriVe V-BelT CheCK
The V-Belts of the saw have been factory-set utilizing
precision standards. Operating the saw with less than the
specified number of V-belts (See Table 6), or belts that are
slipping or are over-tensioned, will significantly diminish
the performance of the saw and may cause damage to
the blade.
V-Belt replacement and Tension adjustment
1. Remove the Belt Guard (Figure 52).
Figure 52. Belt Guard Removal
2. Check the V-belt tension (Figure 53). If the V-belt
