⚠️ SAFETY FIRST

• Make sure the chainsaw is turned off and unplugged / battery removed.

• Wear gloves to protect your hands from the sharp chain.

• Place the saw on a stable surface.

• Make sure the chain brake is not activated.

1. Remove the clutch cover

• Loosen and remove the bar nuts.

• Take off the clutch/side cover so the bar mount area is exposed.

2. Position the guide bar

• If you have a brand-new chainsaw, remove the transportation guards first.

• Slide the guide bar onto the bar studs as close to the drive sprocket (spur) as possible.

• Make sure it sits fully in place on the bar mount.

3. Fit the chain onto the bar

• Make sure the cutting teeth face forward on the top of the bar.

• Place the chain around the drive sprocket, then work it into the bar groove.

• The chain should sit evenly all around the bar.

• Hold the bar and move it forward, so you stretch the chain.

4. Reinstall the clutch cover

• Put the cover back on, ensuring it aligns with the bar studs and tension pin.

• Install the bar nuts finger‑tight, but do not fully tighten yet.

5. Adjust chain tension

Use the tensioning screw to tighten the chain until:

• It touches the bottom of the bar, and you can still pull it slightly by hand (with gloves).

• The chain should “snap back” into the groove when pulled.

6. Tighten the bar nuts

• Fully tighten both bar nuts while holding the bar nose slightly up.

• Recheck the tension afterward.
