How to confirm the fit
- Read your bar. The pitch and gauge are stamped on the guide bar near the saw body — e.g.
3/8" LP .050". - Count drive links. Lay the old chain flat and count the teeth that ride inside the bar groove. This number must match exactly; length in inches is not enough.
- Match all three. Pitch, gauge and drive-link count all have to agree with a row in the table above. Two of three is not a fit.

FAQ
What size chain does a Stihl HT 75 Pole Pruner take?

How do I know which gauge my HT 75 Pole Pruner chain is?
Check the number stamped on your guide bar near the tail, or measure the drive-link thickness with calipers. Common gauges for the HT 75 Pole Pruner are .043" / .050".
Can I put a longer bar on my Stihl HT 75 Pole Pruner?
