Flip over the Mag unit again.
Remove the Top Cover.
Now the Main Arm can be removed to replace the
V-Belt.
Assemble the Mag unit.
Hook the belt to the pulley.
Turn the pulley to t the belt.
To adjust the belt tension properly, put a screwdriver
between the metal Joint Pin and the Main Arm, then
cam out to widen the clearance.
While keeping this position, tighten the bolts to keep
the tension.
There are two types of Pulley Arm. The older one has
just one hole, and the latest one has two holes.
Use the upper hole in the beginning, then switch to the
lower hole when the belt tension comes loose.
2-hole Type (New)
Use the upper hole
1-hole Type (Old)
If the belt has been loosened,
both V-Belt and the plastic
pulley will be worn out quickly.
If the tension is too tight, the
initial resistance must gain too
much.
