How to use a chainsaw bar rail closer

The bar rail closer closes easily and quickly the bar groove to match the thickness properly and to the saw chain drive lengths.

The bearings are heavy-duty and ensure long wear.

The chainsaw bar rail closer is built in high-quality ensuring operation as an accurate fail-safe function. It is perfectly adjustable

What is the need for the bar rail closer?

The need for the bar rail closer is to squeeze the chainsaw bar rails to their original shape.

When it is done perfectly, a new chain fits snugly between the rails to enjoy side-to-side movement.

Thus the performance is better and offers a longer bar life.

The bar rail closer performs this operation, and the new chain is used with the same gauge to a few lengths.

As the bar of the rails starts becoming sloppy, the chain moves in the channel from side to side, and when it moves, it is necessary to squeeze them together.

Chainsaw Bar Rail Closer

The bar rail closer easily closes the bar groove and keeps the chainsaw getting an extra life.

Chainsaw bars offer guidance and are prone to operational wear and tear.

The wear is as uneven rails edges and burs form. Fixing the chainsaw bar rail closer requires a dressing tool.

The chainsaw bar tool has a flat file featuring a straight edge.

It files uneven rail edges that cause continuous wear and ensures the edges are perfectly squared.

Ascertain the bar tool is clamped tightly and file the rails until the edges appear square and smooth.

Inspecting a Chainsaw Bar 

Checking the edges of the bar rail in a chainsaw is important to know if there are localized bumps or pits.

Using the dressing bar or grinding bar, you can fix the rail dips.

The next step is to check the chain for any sideward play.

Horizontally, tighten the chain by hammering its rail, and the third step is to look for uneven rail edges in the chain.

Check if the chain is sitting low on one rail and on the other, it is high.

If so, fix it by dressing the guide bar using the rail-dressing tool.

The bar wires the chain to rotate at fifty miles per hour speed.

The wear rate at such speeds for the bar has an impact on wood and it may damage the bar.

The guide bar is in high-quality steel plates, and it sustains wear as much as possible.

The bar features a narrow groove, and the chain sits in that place. The bar groove edges are known as the rails.

However, they are relatively thin and the foremost to receive blows from the chain that the bar rails are prone to damage.

This chainsaw bar damage is in three types:

Steps to Dress a Chainsaw Bar

A chainsaw bar may be dressed with a belt sander or a flat-file. It will smooth up on the rail edges of the bars. The dressing tool is special and files at 90 degrees angle.

Step-by-step process to use the tool:

Wrapping Up

Solid chainsaw bars are easy to straighten using the correct technique.

While the laminated bars require more effort to perfectly straighten.

Mark the rails before dressing and use a blue market to distinguish the bumps and pits as the file is smoothening the rails.

However, a bent chainsaw straightens, but its lifespan becomes short.
