REMOVAL SERVICE POINT
AA"DRIVE BELT REMOVAL
Due to the adoption of the Serpentine drive system with the
auto-tensioner, the following operation is required:
1. Insert the 12.7sq. spinner handle and etc. into the tool
hole of the auto-tensioner and rotate it counterclockwise
until the auto-tensioner gets to the stopper.
2. Align hole A with hole B for fixing by inserting the L-shaped
hexagon wrench, then remove the drive belt.
Caution
When the drive belt is reused, use a chalk to indicate
an arrow of rotation direction on the back of the belt
so that it can be re-assembled in the same direction
as before.
