FAQs

Which trimmer models does the A-89137 fit?

It is compatible with Makita RST200, RST250, and EH2650 petrol string trimmers.

What is the thread specification for this head?

This head uses an M8 x 1.25 RH (Right Hand) thread mount.

Can I use a thicker line than 2.4mm?

It is recommended to stick to the 2.4mm diameter line to ensure the feed mechanism functions correctly as designed.

Is the bump knob replaceable?

The assembly is designed as an integrated unit; please consult your local Makita service dealer if the bump knob mechanism fails.

How much line does the head hold?

The head comes pre-wound with 3 meters of 2.4mm nylon line.

Is this an authentic Makita product?

Yes, the A-89137 is a genuine Makita replacement part.

Troubleshooting

Line will not feed when bumping

Check if the line is tangled inside the spool or if the line has become welded together due to high heat from over-use.

Excessive vibration during use

Ensure the trimmer head is securely tightened and verify that the line is wound evenly on the spool.

Line breaks too frequently

Avoid striking hard surfaces like concrete or rocks directly with the trimmer line at high speed.

Pros and Cons

Pros

  • Genuine Makita part ensures longevity and compatibility
  • Easy bump-feed mechanism reduces downtime
  • Balanced line diameter handles varied vegetation well
  • Compact 4-inch size is perfect for precise trimming

Cons

  • Limited compatibility to specific petrol trimmer models
  • Requires proper thread alignment during installation
  • Replacement line must be manually wound once the initial 3m is depleted

Setup, Compatibility & Care

To install, ensure your trimmer engine is off and the spark plug wire is disconnected. Remove the old trimmer head by unscrewing it clockwise or counter-clockwise as dictated by your specific Makita model, ensuring you match the M8 x 1.25 RH threading. Hand-tighten the new A-89137 head to ensure it is seated flush against the gear case.

Compatibility: This unit is designed for use with Makita models RST200, RST250, and EH2650.

Care: Regularly clean debris from around the spindle to prevent friction. Check the nylon line for wear and replace it by following the internal spooling guide when the line length becomes too short for efficient cutting.
