Cog Belt; V-Belt - Husqvarna 6690 Manual

The cog belt
The belt tension should not be so loose that it permits
slipping when the machine is locked and the foot
control is depressed. Tighter tension makes more
noise. The belt should not be damaged.
Adjustment
The screws (14/8, 9) in the reduction gear holder
are accessible by means of two holes in the large
cog wheel (14/29). If both the screws are loosened,
a certain adjustment is possible by mowing the
frame for the cog wheel journal (14/20, 25, 26)
one way or the other.
Tighten the screws.
Spare parts: See RA, page 14.

holes in the large cog wheel (14/29) If
