Please make sure you have checked the Plate Checklist and that all the
parts have been received. Before proceeding with these build
instructions.
Unpack the ballscrews and the FK12/FF12 bearing sets.
Be careful to not loose the little circlips that are packed with the FF12
bearings.
To protect the parts you will find that they are covered in a light oil and
it is worth wiping this all off before starting to assemble. Also wearing

rubber nitrate gloves to protect your hands from this thin oil
penetrating your skin is advised.
Slide the bearings over the end of each ballscrew. If a little bit tight
then gently tap on with a tube that matches the inner race. Do not
hammer the whole bearing as you could damage it.

It is up to you when you apply grease, but can be easier as you
assemble or you can do it at the end of the build.
We always find it easier to place the grease into a syringe first and then
squeeze some grease into the ballnut until it comes out the sides. Then
gently turn the ballnut over any excess grease to make sure it works it’s
was in.
After squeezing the grease in then screw in the nipples and tighten off.
If using a grease gun, first screw the nipples in place and apply grease.
