It’s recommended to check the owner’s manual for lubrication instructions and to clean and lubricate the #56 shafts, #58 and #60 drive as a starting point. Some users have had success with using a silicone lubricant or WD-40 on the guide pins.

If the problem persists, it may be necessary to contact Bosch service or consider selling the saw and purchasing a different brand.

Problem 1: Difficulty Cutting Thin Strips

One of the common issues reported with the Bosch 4100 table saw is difficulty cutting thin strips. This can manifest as the saw not making clean, precise cuts or the wood splitting or breaking.

Possible Causes

There are several possible causes for this problem. The blade may not be adjusted properly, causing it to be too high or too low. The blade may also not be sharp enough, resulting in rough or uneven cuts. The fence may also be out of alignment, causing the wood to be cut at an angle rather than straight.

Solutions

To fix this problem, the first step is to ensure that the blade is adjusted properly. Refer to the owner’s manual for instructions on how to adjust the blade height. Next, check the sharpness of the blade and sharpen or replace it if necessary. Finally, check the alignment of the fence and adjust it if needed. Keep in mind, it’s important to regularly check and adjust the blade and fence to avoid this problem.

Problem 2: Issues With Dowel

Another common problem with the Bosch 4100 table saw is issues when cutting dowels. This can include difficulty making accurate cuts, the dowel splitting or breaking, or the saw not cutting through the dowel at all.

Possible Causes

The cause of this problem can be similar to that of difficulty cutting thin strips. The blade may not be adjusted properly, causing it to be too high or too low. The blade may also not be sharp enough, resulting in rough or uneven cuts. The fence may also be out of alignment, causing the dowel to be cut at an angle rather than straight. Additionally, the dowel may be too thick for the saw blade to handle properly.

Solutions

To fix this problem, the first step is to ensure that the blade is adjusted properly and is sharp enough. Refer to the owner’s manual for instructions on how to adjust the blade height and sharpening the blade. Next, check the alignment of the fence and adjust it if needed. It’s also important to use the appropriate size of saw blade for the thickness of the dowel. If the problem persists, it’s recommended to test different blades and choose the one that works best for your specific dowel size.

Problem 3: Blade Adjustment Mechanism

One of the most reported issues with the Bosch 4100 table saw is the blade adjustment mechanism not functioning properly. This can include the blade not raising or lowering, gears turning but the blade not moving or the wheel not making the gears turn.

Possible Causes

This problem can be caused by a variety of factors. The gears may not be lubricated properly, causing them to seize. The parts of the mechanism may be worn out, causing them to not function properly. The problem can also occur if the saw is not used or maintained regularly.

Solutions

The first step to fix this problem is to ensure that the gears are lubricated properly. Refer to the owner’s manual for instructions on lubricating the gears. It’s also important to keep in mind that lubrication should be done regularly.

If the gears are still not functioning properly, it’s recommended to check for worn out parts and replace them if necessary. If the problem persists even after checking the lubrication and replacing worn out parts, it’s recommended to contact Bosch service for further assistance.

Tips While Working With a Saw

  1. Use the right blade for the job: Using the correct blade for the type of wood and cut you are making can help prevent problems with the saw and improve the quality of your cuts.
  2. Check the alignment of the miter gauge: The miter gauge is used to make angled cuts, and if it’s not properly aligned, it can cause the saw to cut at an angle, resulting in uneven or inaccurate cuts.
  3. Keep the saw clean and free of sawdust: Sawdust can build up and cause problems with the saw’s moving parts, so it’s important to clean the saw regularly and keep it free of sawdust.

Use the Proper Technique When Cutting

Using the proper technique when cutting can help prevent problems with the saw and improve the quality of your cuts. Make sure to use a steady, consistent pace and keep your hands and fingers away from the blade.

  1. Check for loose parts: Before using the saw, make sure that all parts are securely in place and tightened.
  2. Check the blade guard: The blade guard is a safety feature that protects the operator from the blade, make sure it’s in good condition and properly installed.
  3. Use proper extension cords: Make sure that the extension cord you’re using is of the correct gauge and length.
  4. Use proper Personal Protective Equipment(PPE): Always wear eye and ear protection, gloves, and dust mask when working with the saw.
