I believe this is a Performance Power (B&Q) brand
B&Q customer services may be able to help you with a manual
Solent tools may be able to sell you spares
I have recently bought a new table saw.
There's a mitre fence which I do not use
There's a blade guard which I do not use
There's a Rip Fence which I do use
And a riving knife which I have yet to remove - it prevents kick-back
You would do well to make a simple cross-cut sled - I use mine all the time (very often) there are videos on Youtube.
