Belt Tension Adjustment
► The objective of all belt adjustments is to remove any slack without stretching the belt.
On the Feed module and body module, provision is made for the adjustment of five
drive belt tensions. Loose belt tension can cause continuous frictions and abrasions
between the teeth of pulley and belt, which ultimately reduces the lifespan of the belt
dramatically. Therefore, it is critical to properly adjust the belt tension.
► Drive Belts Tension of Body Module to Feed Module
1. First, place the belt in the direction shown in the below picture, and assemble the Idle
Tension Bracket at the end of the assembly process.
2. Put the embossing behind the Idle Tension Bracket inside the square home, and push
it in the direction of the arrow. Slightly snug the M4 screw.
3. Adjust the Idle Tension Bracket so that the belt tension at the longest belt point has
the tension of about 400~600g, and tighten the screw completely. Make sure that the
screw is not loose which can loosen the belt tension.
4. Slowly turn the Green Knob and double check if any belt vibration exists.
