PP250MS Mitre Saw. Servicing and has anybody got the manual?

I'd like to know how to maintain my power mitre saw made in 2001 for B&Q called the PP250MS. It has a single linear shaft which is lightly pitted so affecting travel. I can't get the manual to assist servicing. I'm proposing to smooth the shaft insitu and then make some kind of flexible cover to avoid waste build up.

If anybody can send a scan of the manual I'd be very grateful. Please no spam.
