Description
STIHL OEM 3689 005 0081 Rapid Micro 26RM3 81E Chainsaw Chain
Keep your STIHL chainsaw cutting safely and efficiently with the genuine STIHL OEM 3689 005 0081 Rapid Micro™ 3 (26RM3) 81E chainsaw chain. This semi-chisel, low-kickback chain is designed to deliver smooth, dependable cutting performance while requiring less frequent sharpening than aggressive full-chisel chains. Built for professional forestry work and demanding property maintenance, the 26RM3 chain offers an excellent balance of cutting speed, durability, and user safety.
The current listing also notes this chain is for certain pre-2023 setups using bars that do not have the graphic shown in the photo. Chain fitment depends on your guide bar specifications—not just the chainsaw model.
Always verify your current chain specifications:
- .325" Pitch
- .063" Gauge
- 81 Drive Links
- 26RM3 (Rapid Micro 3) chain designation
Model fitment alone does not guarantee compatibility.
If you're unsure, contact us with your STIHL model number, guide bar information, and current chain number, and we'll help verify the correct replacement before you order.

Installation Tips
- Disconnect the spark plug before servicing the saw.
- Inspect the guide bar groove and oil ports, cleaning them before installing the new chain.
- Check the drive sprocket for wear and replace it if the teeth show hooking or excessive wear.
- Install the chain with the cutter edges facing forward across the top of the guide bar.
- Adjust chain tension so the drive links remain engaged in the guide bar while the chain can still be pulled smoothly by hand.
- Run the saw briefly after installation and recheck chain tension, as new chains stretch during break-in.
- Maintain proper lubrication with quality bar and chain oil to maximize chain and bar life.
- Sharpen the chain at the first sign of reduced cutting performance rather than forcing dull cutters through the wood.
