Step 2 : Close the belt with the connection plate assy and be sure that all the teeth of the connection plate
are used to hold the belt.
Step 3 : Turn the 2 screws on the return pulley an equal amount of turns in CW (Clockwise) in order to get
a little tension on the belt.
Step 4 : Install the cutting head (Please refer to 6.2.6. Cutting head).
Step 5 : Move the head manually from the left to the right and look for the tracking of the belt on the return
pulley.
If the belt moves upwards, turn the top screw CW or the bottom screw CCW (counter-clockwise).
If the belt moves downwards, turn the top screw CCW or the bottom screw CW.
The target is that the tension of the belt stays stable at the surface of the return pulley on the
complete range of the cutting head.
Step 6 : Similar to step 5 check the track of the belt on the drive pulley.
If the belt moves upwards turn the screw 9 (Please refer to the picture mentioned below) CW.
If the belt moves downward turn screw 9 CCW.
