S4S 4 x 36 Inch Bench Sander FAQ: Your Questions Answered

Belt Selection: Choosing the Right Grit for Your 4 x 36 Inch Sander

The type of material you’ll be sanding will determine the best belt grit for your 4 x 36 inch heavy duty belt sander. The S4S sander can accommodate various belt types, ensuring you can achieve your desired finish on various surfaces.

  • Wood: For general sanding of wood, start with a medium grit (80-120) and progress to finer grits (150-220) for smoothing and finishing.
  • Metal: Use aluminum oxide or zirconia alumina belts for metal sanding. Start with a coarse grit (36-60) for heavy removal and progress to finer grits (80-120) for finishing.
  • Plastics: Aluminum oxide or silicon carbide belts work well for plastics. Start with a medium grit (120-180) and progress to finer grits (220-400) for polishing.

Note: Always test your chosen belt on a scrap piece of material before sanding your workpiece to ensure it produces the desired results.

Belt Tracking and Adjustment: Keeping Your 4 x 36 Inch Sander Running Smoothly

Proper belt tracking is essential for even sanding and preventing premature belt wear. If your 4 x 36 inch bench sander’s belt is not tracking correctly, follow these steps:

  1. Loosen the nut (#8) on the tracking mechanism.
  2. Use the hex bolt (#7) to adjust the tracking until the belt runs centered on the platen.
  3. Once the belt is tracking properly, tighten the nut (#8) to secure the adjustment.

Tip: You’ll need two open-end wrenches for this adjustment.

Troubleshooting Tracking Issues:

  • Try a different belt: Sometimes, belts are not manufactured perfectly. If the problem persists, try a new belt from a different batch.
  • Clean the tension shaft and spring: If the tracking issue continues, thoroughly clean the tension shaft and spring, then replace the belt.

Check for crown on the lower drive pulley: Use a straight edge to check if the lower drive pulley has a crown (a slight raised area in the center). If the pulley is flat, it may need to be replaced.

Changing the Sanding Belt on Your 4 x 36 Inch Bench Sander

To change the sanding belt on your 4 x 36 inch bench sander:

  1. Squeeze the sanding belt: This will draw the yoke downward.
  2. Rotate the tracking mechanism (#11) parallel to the tension shaft: This will release the tension on the belt, allowing you to remove it.
  3. Install the new belt and squeeze it again.
  4. Rotate the tracking mechanism (#11) perpendicular to the tension shaft: This will apply tension to the new belt.
  5. Adjust the tracking if necessary.

Maintenance: Keeping Your 4 x 36 Inch Bench Sander in Top Condition

Regular maintenance will prolong the life of your 4 x 36 inch bench sander and ensure optimal performance.

  • Daily Cleaning: Thoroughly clean the entire machine daily, removing dust and debris.
