The most essential tool to have is a good quality, accurate try-square, or even better a metal engineers square.

Here i'm checking the fence is square (90 Degrees) to the machine bed, this is absolutely essential for accurate results.

I use the handle to lock it off, most jointers will have this facility, because sometimes the fence will needed to be tilter for angle work.

The table is able to move, this determines the depth of cut. The handle to do this is usually at an angle on the right hand part of the machine, under the machine bed.

There are graduations in 0.5mm - (in this case from 0 - 2.5mm) The mark on the machine top should align with one of the markings on the scale - this will vary from machine to machine.

Always adjust the safety bridge guard so there is almost NO blade showing, but don't have it too tight against the wood otherwise you wont be able to freely pass it when using the tool.

Here i'm using my wood as a guide, so I don't over tighten it.

ALWAYS wear safety eye protection when using a machine like this, as large chips fly off at fast speeds from time to time.

Its also suggested that you wear a dust mask, and hearing protection when using any power tools.

Pass your work through slowly, holding it tight against the fence, and making sure it is in contact with the machine bed at all times. Pass it over the blade with a push stick, or work aid for safety.

Don't try to joint very small bits of wood as it is unsafe, and they can catch etc.

Its suggested that you do a test cut before you use the machine on your actual work.

Use a accurate square to check the results - Perfecto!
