FAQs
What is the length of this Makita guide bar?
The Makita 958030611 guide bar has a length of 30 cm, which is equivalent to 12 inches.
Which Makita chainsaw models is this bar compatible with?
This bar is compatible with Makita chainsaw models DUC302, UC3010A, DUC307ZX2, and DUC302Z.
What does '1.1 mm gauge' mean?
The gauge refers to the thickness of the drive links on the chain that fit into the bar's groove. A 1.1mm gauge is a narrower width, typically used with specific narrow-kerf chains for reduced cutting friction.
How often should I rotate the guide bar?
For even wear, it is recommended to rotate the guide bar 180 degrees after every few uses or as part of your regular maintenance routine.
Can I use this bar on a non-Makita chainsaw?
While it is an Oregon bar, it is specifically designed and recommended for the listed Makita models. Using it on other brands may result in improper fit, poor performance, or damage.
What maintenance is required for the guide bar?
Regular maintenance includes cleaning sawdust from the bar groove, ensuring proper chain lubrication and tension, and rotating the bar for even wear. Inspect for damage regularly.
Is this a replacement part or an upgrade?
This is a genuine Makita replacement guide bar designed to fit specific Makita chainsaw models. It offers standard performance for those compatible models.
Troubleshooting
Chain not cutting straight
Check for bar rail wear, ensure the chain is properly tensioned, and verify the bar is not bent. Rotate the bar or replace if worn.
Chain is difficult to move around the bar
Check chain tension; it may be too tight. Also, clean debris from the bar groove.
Bar lubricant not reaching the chain
Ensure the oiler port on the chainsaw is not blocked and that the bar groove is clean. Check the chain oil reservoir level.
Excessive vibration during use
Verify chain tension is correct and that the chain is sharp. A dull or improperly tensioned chain can cause vibration. Inspect the bar for damage or excessive wear.

Setup, Compatibility & Care
Compatibility:
This 300mm (12-inch) Oregon bar is specifically designed for the following Makita Chainsaw models:
- DUC302
- UC3010A
- DUC307ZX2
- DUC302Z
Always verify your chainsaw model number before purchasing to ensure compatibility.
Setup:
- Ensure the chainsaw is turned off and the chain brake is engaged.
- Remove the chain cover nuts.
- Remove the chain cover.
- Loosen the chain tensioning screw to allow the chain to slacken.
- Remove the old guide bar (if replacing).
- Position the new 958030611 guide bar, ensuring the drive links of the chain engage with the sprocket at the bar's nose.
- Adjust the chain tension using the adjustment screw until the chain is snug but still can be pulled around the bar by hand with gloves on. Ensure the chain is not sagging.
- Reinstall the chain cover and tighten the cover nuts evenly.
- Disengage the chain brake and run the chain briefly at half throttle to seat the chain. Re-check tension and adjust if necessary.
Care:
- Cleanliness: Regularly clean the bar groove with a small brush to remove sawdust and debris. A clogged groove can impair lubrication and increase wear.
- Lubrication: Ensure the automatic oiler is functioning correctly and the bar groove is adequately lubricated during use.
- Tension: Maintain proper chain tension at all times. A loose chain can derail, and a chain that is too tight can cause excessive wear on the bar, chain, and sprocket.
- Rotation: For even wear, rotate the guide bar 180 degrees after every few uses. This ensures both the top and bottom edges of the bar groove wear evenly.
- Inspection: Periodically inspect the bar for signs of wear, such as "bar rail" (burring on the edges) or a worn groove. If significant wear is present, replace the bar to maintain optimal cutting performance and safety.
