V-belt idler out of adjustment.

Check idler. (See Check And Adjust Net Wrap V-Belt Idler Tension in Service—Net Wrap section.)

Weak gas springs.

Check springs for proper force.

Too many net wrap layers applied.

Normally no more than three net wrap layers are needed. Excess layers can appear to be loose.

Maintain rated PTO speed while applying the net wrap. If difficult crop conditions require varying PTO speed while baling, return to rated speed for applying the net wrap.

Turn slip clutch alert PTO speed sensor on to control spacing independent of speed.

Bale size and shape not uniform.

Make bales uniform in shape. Follow operating instructions in Operating the Baler section.

If applying net to a smaller bale with override switches, the small bale has more net wrap layers unless the controller is readjusted.

Too much clearance between the net wrap guide pan and belts.

Adjust rear of pan to contact belts at the lower rear gate roller (see Check And Adjust Lower Net Wrap Guide in Service—Net Wrap section.)

Remove buildup. In some crops, reducing PTO rpm reduces buildup tendency. Ejecting bale with PTO running reduces buildup in some conditions.

Oversize bale compresses crop buildup in the lower gate belt guide area.

Adjust the oversize bale switch. (See Adjust Oversize Bale Switch in Service—Baler section.)

Remove buildup. In some crops, reducing PTO rpm reduces buildup tendency. Ejecting bale with PTO running reduces buildup in some conditions. (See Adjust Oversize Bale Switch in Service—Baler section.)

Actual bale size is larger than displayed diameter. Adjust bale size display to match actual diameter. (See Adjust Bale Diameter Display in Operating the Baler section.)

Oversize bale can allow some strands of net to wrap around number 11 idler roller.

Adjust the oversize bale switch. (See Adjust Oversize Bale Switch in Service—Baler section.) Remove net from all rollers.

Actual bale size is larger than displayed diameter. Adjust bale size display to match actual diameter. (See Adjust Bale Diameter Display in Operating the Baler section.)
