Sharpen · 8 steps

Step 1

Make the saw safe

Engine off and cool. Chain brake on. Gloves and eye protection.

Saw safe

Step 2

Rod into the crank

Use the rod size for your saw (see above). Tighten the set screw. Do not crush the rod.

Correct rod in

Step 3

Clamp on the bar rails

Knobs loose first

Put the jaws on the bar rails. Not on the chain only.

Jaws on rails

Step 4

Latch behind the tooth

Pick the crank hole for this cutter side. Put the latch behind the cutter. Tighten it.

Latch set

Step 5

Tighten all knobs

The jig must not move on the bar.

No slip

Step 6

Crank · light, even

Same count · every tooth

Do not force it. Hard sparks or no bite: stop. See “Problems”.

First tooth done

Step 7

Next tooth · same side

Loosen. Move to the next cutter that faces the same way. Repeat steps 4–6.

Then use the other crank hole for the other side. Same count.

Both sides done

Step 8

Depth gauges · every 3rd

Every third sharpening: flat file + depth gauge tool. Husqvarna 545: 0.65 mm.

Gauges checked

Steps 1–7: general bar-clamp jig method, made short. Not a Husqvarna procedure. Follow your jig’s own sheet.

Does it cut now?

Problems · tap

Jig slipsKnobs · rails

Loosen. Put the jaws on the bar rails again. Tighten all knobs.

Sparks · no biteWrong or dull rod

545 = 4.8 mm rod. 460 = 5.5 mm rod. HT 131 = 4.0 mm file. Change a dull rod.

Shiny but no cutDepth gauges · chain

Depth gauges too high, or wrong rod size. Do step 8. Chain still won’t move on the bar? That is a different fault: check the clutch and drive sprocket.
