Sharpen Makita DUC 355Z / Swap Chain

[Witterings]

Most saws of the above size seem to use a Oregon 91PX chain which is 4mm file size and compatible with the Stihl 2 in 1 easy file but this uses a 90PX which use a 4.5mm file ... but the easyfile only comes in 4.8mm as teh next smallest size but I'm guessing that's too big???

 

Ideally I'd like to just use 1 file for all the saws I have and it'd be cheaper to buy a new chain than a 2nd easy file as I'm guessing the generic 4.5mm files won't fit in an easy file either??

 

Someone suggested that the Stihl Pico Micro Mini has the narrower gauge and could be an alternative ... is there any risk that could do any damage to the saw as they may chosen the specific chain to lessen any strain on an electric as opposed to petrol powered motor ????

If anybody can help with any of the above it'd be much appreciated!
