Practical guide

Which chain fits my chainsaw?

The correct chainsaw chain is determined by pitch, gauge and the number of drive links. All three values must match.

Choose the safest starting point

01

I know the chainsaw model

Choose the complete make and model first. If several variants exist, also check the product number on the rating plate.

02

I can read the guide-bar dimensions

Enter pitch, gauge and drive-link count. A dimensional match identifies a chain candidate, not whether an unknown guide bar fits the saw.

Search by dimensions

Read the guide-bar markings

Look near the guide-bar mount for the pitch, gauge and drive-link count. The existing chain may also be marked. Switch off the saw and follow its safety instructions before examining the equipment.

Pitch

Pitch describes the spacing in the chain and must match the drive sprocket and guide-bar nose. Examples include .325, 3/8 and 3/8 mini.

Gauge

Gauge is the thickness of the drive links that run in the guide-bar groove. Common values include 1.1, 1.3, 1.5 and 1.6 mm.

Drive-link count

Count only the drive links that run in the groove. Two chains with the same pitch and gauge can still have different lengths.

3/8 and 3/8 mini are not the same

The names look similar, but they are separate technical classes in this catalogue. Never replace one with the other based only on the text “3/8”.

Why 14 or 16 inches is not enough

The nominal guide-bar length does not uniquely determine the chain. Guide bars with the same inch length can require different pitch, gauge or drive-link count.
