I need an engine rebuild kit for a SX66 Baumr ag chainsaw is there such a kit? Corrie

Baumr-AG Pole Saws Instruction Manual (datastreamserver.com)
Page 36 of manual says chain not to be spinning before trying to cut. Need pull trigger to start rotation.

https://www.manualslib.com/manual/1307779/Baumr-Ag-660ex.html?page=24#manual

read the user manual first as it will show any parts used for transport that have to be removed The user manual shows that the chainsaw comes supplied with plastic spacers (BB) underneath the chain drive cover and over or around the chain drive cover studs (CC)
Those spacers are for shipping purposes only and must be discarded before mounting the chain bar
The manual that I got that from can be downloaded as a baumr AG chainsaw manual pdf from www.datastreamserver.com>bau
The last baumr product( impact drill) that I purchased included the user manual in the box

Try www.chainsawspairs.com.au it looks to me there are not any UK suppliers. Good luck.

Loosely based on an Electrolux chainsaw so Oregon bars should also fit

Cant find much on your machine as its an obscure make and model. This brings with it the ease of sourcing parts, sometimes its better to stick with known brands for this reason.

I managed to find this, it might be worth comparing it to the one on your machine. Hope it helps.

• There should if available for your model type a maintenance kit neccesary for your model or all the used o-rings and sometimes special tools because there are special buna-n or nbr o-rings used sometimes braun or green colored on some parts and gaskets, seals and rings used and allways if your tool is leaking then replace the impact bold in front of the spindle if you have find the right drawing for your model type
• The right lubrication is very important in combination of the o-rings because of the heat building release by rotating and hammering and a leaking tool has oft made all o-rings hardenet because of the failed pneumatic working loose of lubrication dried out principal it becomes very dry internal on some places and much to hot .

Where I have a bit of a problem is that this question about a chainsaw is headed 'Problem with Video Cameras'. Maybe Fixya's fault.
