TL;DR
Feed roller slipping causes workpieces to stall or track crooked through the sander. Clean the rollers, check nip pressure, and inspect the drive chain or belt for wear.
What you might see
- workpieces stalling in the sander
- workpieces skewing while feeding through
- feed rate inconsistency
- burn marks on workpiece faces from stalled sanding contact
Likely causes
Feed roller rubber surface glazed from resin accumulation
Feed nip pressure too low for the workpiece thickness
Drive chain or belt worn, losing drive torque to the feed rollers
Feed roller rubber worn to the point where grip is insufficient
Required tools
- Roller cleaning compound
- Drive chain or belt tension gauge
- LOTO kit
Safety first
- Lock out before reaching into the feed roller area. Feed rollers create a nip point hazard.
- Sanding dust accumulation is a fire and explosion hazard. Maintain dust collection during and after maintenance.
Procedure
- 1
Lock out the machine and open the feed roller access cover.
Warning: Feed rollers are driven nip points. Lock out before reaching into the feed path. - 2
Inspect the roller rubber surface for glazing, hardening, or resin deposits.[1]
- 3
Clean all rubber roller surfaces with a roller cleaning compound or solvent appropriate for the rubber type. Allow to dry completely before testing.
- 4
Check the feed nip pressure setting against the machine specification for the workpiece thickness range being processed.[1]
- 5
Inspect the drive chain or belt for stretching, worn links, or missing teeth. A stretched chain slips under load.
- 6
Check chain or belt tension and adjust to the specification. Replace if wear is beyond the adjustment range.
- 7
Run a test piece after each correction. Confirm the workpiece feeds straight and at a consistent rate before resuming production.

How to fix sanding belt tracking problems on a Timesavers 2300 Wide Belt Sander
Belt tracking off to one side tears the belt edge and causes uneven sanding. Adjust the tracking sensor and idler roller tilt in small increments until the belt runs centered.
How to eliminate cross-grain sanding marks on a Timesavers 2300 Wide Belt Sander
Cross-grain marks are usually caused by a worn or clogged belt, incorrect grit sequence, or feed speed mismatch. Replace the belt, check grit progression, and adjust feed speed to match the stock removal rate.
