11 Blade Shaft V-Belt Tension
(See Figures 1-3)
This saw is equipped with high tension banded V-belts.
The belts are properly tensioned at the factory but after
a few hours of operation they will stretch and become
loose.
To Tension V-Belts:
• Turn Engine Start Switch (1H) to the “0” (OFF)
position.
• Using the Blade Shaft Wrench, loosen the horizontal
clamping bolts (3K) at the front of the machine.
• Turn each of the two (2) vertical Tensioning Bolts (3J)
[at the front of machine, below the Gear Box (3A)]
CLOCKWISE until the V-Belts (3M) are tight.
• Replace V-Belts (3M) in complete sets only.
• For optimum V-Belt tension use Goodyear TensionRite™
Strips, P/N 191368. TensionRite™ strips are supplied
with belts purchased from Husqvarna.
Never tension V-Belts (3M) beyond the
original factory tension. Loose V-Belts result
in poor saw performance and short belt life.
