💡 How do you keep side load low and extend service life on a manual spindle tool?

- Tighten the hex bolts firmly against the sync wheel so rotation stops drifting mid job
- Pick a lighter shaft diameter so the motor torque doesnt overheat during quick cuts
- Keep the rubber gaskets clean since dry seals wreck the internal alignment fast
- Grab spare washers early because ready swap parts keep your garage workflow handy.
