3. Check V-belt tension by using a tension meter (3.0 lbs.)
against the inside belt at a mid point between the two pulleys,
or by deflecting the center belt at a mid point 3/16" (5 mm).
4. DO NOT over or under tighten the V-belt. Severe damage
can occur to the saw and engine crankshaft if the belt is
over-tensioned. A decrease of power to the blade and poor
performance will result if the belt is under-tensioned (loose
on pulleys).

V-belt Alignment and Tensioning
This saw is equipped with a premium V-belt that has been aligned
and tensioned by factory personnel. The V-belt must be aligned
and tensioned for proper operation of the saw.
Use the following procedure to check the alignment of V-belt:
1. Remove the bolts that secure the V-belt cover (Figure 9) to
the saw frame.
2. Check uniform parallelism (Figure 10) of V-belt and pulley
(sheaves). Use a straight-edge or machinist's square against
both pulleys and adjust both pulleys until equally aligned.
NOTE
V-belt alignment must be
rechecked after adjusting belt
tension.
