the belt stretches slightly as the saw is used.
most of the belt stretching will happen during the
first 16 hours of use, but it may continue in small
increments through continued use.
to ensure optimum power transmission from
the motor to the blade, the belt must be in good
condition. replace the belt if it becomes cracked,
frayed, or glazed.

this slowly and take care not to apply too
much pressure to the belt.
Note: Be careful not to damage the motor,
and do not force it up further when it becomes
difficult to move the handwheel.

the belt is pushed with moderate pressure,
raise the motor upward.
NOTICE
Do not overtighten the belt. If you do, it
could decrease the lifespan of the motor
