Inspect the timing belt for proper tension by pressing down on the belt between the pulleys.
The belt should have slight give but should not be loose enough to skip teeth.
If the belt is too loose, you'll need to adjust the eccentric shaft cap to increase tension.
If the belt is too tight, the system will be hard to move and may cause premature wear.
Proper belt tension is critical for smooth operation and longevity of the system.
