How to set the perfect chain tension on a TPC165

How to set the perfect chain tension on a TPC165

Why do you need to check and change the tension?

 

Put simply… If you have the incorrect tension, it costs you more money!

 

A chain that is too tight can disform the black blade and result in some wonky cuts.

This will cost you money as you will ruin the composite panels and need to buy more.

 

If your chain is too slack and it's not tight enough, then the blade will move around and the chain will not run efficiently.

You'll wear your chain out faster and that will cost you money to replace.

What is the process of checking tension?

 

  1. Remove the black casing (the part that has the extractor outlet on) from the unit
  2. Find the midway point of the entire blade.
    1. IMPORTANT POINT – the mid-way point of the shole blade, NOT just the part that is exposed before you removed the casing.
  3. Put your hands on either side and grab hold of the chain
  4. Pull your hands apart from each other gently

 

What does perfect tension look like?

There should be a little bit of wiggle room between the chain itself and the actual black blade when you move your hands apart.

You should be looking for about 1.5 millimeters of play on either side.

If this is correct, you should be able to see about half of the small hole in the chain linkage.

 

How do you change the tension?

  • If your chain is too tight, whilst the black housing is removed, use a screwdriver to make it slacker.
  • More than likely, what you'll find is that over time, your chain will become more and more slack just as the linkages wear and it does more work… in this case, do as above but tighten the screw.
