DUH601z cordless makita trimmer

Recommended Posts


Sounded noisy (clattering noise) so topped up the grease (even though it hasn't done 100hrs yet) which is the service interval for greasing


Then after just stopped working/cut & our smoke from motor 😕


Any ideas?


Annoying as was a good machine.....

Any bearing/electric motor experts?


Being looking up about bearings specs seems very complicated to understand all the codes best just to stick with the official part listed?




Or can swap out with a eqivalent? (Might be  an upgrade in quality if SKF etc?)


608ZZ is the one needed at the  gearbox end of the armature (not 695zz that was ok)




Vital  also to clean all grease from gearbox as has metal swarf may be balls hidden in it?

Personally I'd be very happy with the SKF from simplybearings, will be good quality. Whether that's better probably depends on the shipping cost more.

What about changing the 695 anyway when it's apart?

I think it is just a bearing, if you have the 608 code then it's the right size and type (deep groove etc) and then Z for metal seals.

SKF E2 Energy Efficient Bearings

SKF E2 Energy Efficient Bearings are deep-groove, shielded, ultra-low friction bearings that feature an optimised design, balanced between internal geometry, grease and cage type.

With 30 to 50% lower friction when compared with standard SKF bearings, the energy savings achievable when using SKF Energy Efficient Bearings are substantial, and the bearing life is extended significantly - in most cases more than double.

SKF E2 Energy Efficient Bearings offer ultra-low friction and typically generate less heat and can operate at higher speeds than ISO or SKF Explorer Bearings.

Dimensionally fully-compatible with standard bearings

Typical applications for SKF Energy Efficient Bearings include:

Electric motors up to 37kW (50HP)
Light to medium-loaded machines with shaft diameters up to 60mm
Excellent drop-in replacement for in-service electric motors
