Common Problems With The Oiler And How To Solve Them

If you’re looking for a chainsaw that’s powerful and easy to use, then the Stihl ms251 is the perfect option for you. It’s perfect for easily cutting through wood, branches, and other tough materials. When it comes to oiling your equipment, you want to ensure that you’re doing it correctly and efficiently.

  1. Poor oil distribution – If the oiler isn’t distributing the oil properly, it will cause your Stihl ms251 to sputter and misfire. You’ll need to clean the lines and adjust the valve to fix this.
  2. Slow or inconsistent oil flow – If your engine is losing power or struggling to start because of poor fuel delivery, there are likely blockages in the system caused by debris accumulation (e.g., leaves). In this case, cleaning out the surrounding filters and adjusting chain tension may be necessary remedies before addressing the issue of poor oil distribution.
  3. Damaged or worn parts – If you see any signs of wear and tear on your oiler, it may be time to replace it. This is especially important if the machine starts making an unusual noise or experiencing other problems that are difficult to diagnose.

In most cases, this can be remedied by adjustment of the valve and cleaning all obstructions in the oiler system.
  5. Faulty spark plug – If your engine is misfiring or sputtering, there’s likely a faulty spark plug installed. In this case, you’ll need to replace the plug and check for any debris or carbon build-up in the ignition coil.
