  1. IMPORTANT: Poor belt tracking is not normal and can lead to belt lace damage and subsequent belt failure. Every effort must be made to correct belt tracking issues when they are discovered.

    Start engine and wait for control units and CommandCenter™ display to initialize.

  2. Select daily service icon (A) on display.

  3. Select load wrap mode icon (B). Load wrap mode appears on-screen.

  4. External tether control unit is now active.

  5. CAUTION: Module builder gate and handler are heavy and can cause serious injury or death. Before operating module builder tether control, make sure that no one is on or near accumulator, module builder, or handler.

    Best view of belts is obtained when there is no roll of wrap on upper wrap rollers.

    From handler platform, look through wrap box and observe position of module builder belts in relation to rear guides.


  8. Climb down from platform and return handler ladder to harvest position.

    Press high engine speed button to run engine at high speed.


  10. Press and hold foot switch (A) to run material handling system for 5—10 minutes.

  11. Release foot switch. Press low engine speed button.

  12. Lower ladder. Climb onto platform and again observe position of module builder belts in relation to rear guides.

  13. NOTE: Belt edges rubbing on rear guides is normal and is not considered to be poor tracking.

    Poor tracking occurs when belts ride up on rear guides and start to curl. Poor belt tracking can cause belts to ride on one another and stretch unevenly and further hinder belt tracking. Poor belt tracking can also cause the lace pin to break and the lace to pull out of the belt.

    Using the following table, select the condition that best describes the belt tracking observed and perform the corresponding corrective action.

     

    Observed Belt Tracking

Reduce Excess Tracking to the Left

Belt tracking is controlled by adjusting the position of the upper rear gate rollers. Adjustment must be made on one side of machine only. Adjustments are made in small increments and tracking is rechecked after each adjustment.

If belts are tracking to the left, the upper rear gate roller on the right side must be adjusted forward. If no further adjustment is available on the right side roller, then the left side roller must be adjusted rearward.

The procedure for adjustment of the right side roller is the same as for the left side roller previously described.

IMPORTANT: Poor tracking of an individual belt is not normal and must be corrected as soon as the problem is discovered. An individual belt tracking poorly can ride on the belts on either side of it and cause damage to or failure of all three belts.

If most of the belts are tracking properly between the guides, but one or two of the interior belts are riding up on a guide, check for cotton buildup around the front rockshaft rollers and remove debris. If no buildup is present, flip the individual belt that is tracking poorly to reverse the tracking direction. Flip belt or belts as follows:

  1. Select RMB service mode icon (A).

  2. Select RMB service icon (B). RMB service screen appears.

  3. Press button D on tether control unit to place gate in cradle.

Once belts are tracking properly, repeat steps to run machine for 5—10 minutes. Then, lower handler into wrap feed position and lower ladder. Measure clearance and adjust as necessary, as follows:

  1. Measure distance (A) between outer baler belt and gate sidewall directly behind lower gate roller. This distance must be 19 mm (3/4 in.) or less. If distance is greater than 19 mm (3/4 in.), adjustment is required.

  2. Adjust clearance by moving rear belt guides (B) and front belt guides (C) toward the outside of the machine to force the outer belt closer to the gate sidewall.
