This is the content required for an introduction to our Sliding Table Saw - reading this does NOT replace the mandatory session with a tutor! It will make it a lot quicker though ;-)

If you are ready for this introduction, please reach out to the following tutors: NAME-HERE

Let's begin! First off, make sure you have read the machine's wiki page.

Safety

Personal protection:

A dust mask may also be necessary depending on the material you are cutting!

Dangers	Precautions
sharp and rotating exposed blade, with chances of flesh wounds and missing limbs will keep spinning for a bit after turning the power off!	your hands need to stay well clear (at least 120mm) of the blade at all times use a push stick if you have something small to cut (below 240mm width)! use an extra piece of scrap wood if you have something very small to cut (below 30mm width!) do not use the sliding table saw when you are alone in the Space, you might need another Maker to call help in case of an accident make yourself familiar with amputate bags for the worst case height of the blade: make an informed decision high blade: cuts "down", not pushing against you - makes the saw easier to use and leads to less of a difference between cut distances on top and bottom BUT it exposes a lot of the dangerous blade low blade: lower risk of serious injury (could cut into your finger, not as easily trough it) but you have to push the workpiece harder use the top blade guard whenever it is not hindering your cut - it should be fixed so its bottom edge is horizontal and at least 10 mm above the workpiece
kickback - if the workpiece is pressed against the blade's side, it can be thrown towards the operator! check out this video on YouTube to see what that looks like	File:New photo needed.png DO NOT use sliding table + parallel fence at once! never constrain the workpiece in more than one direction during the cut - use fixtures on the sliding table OR the parallel fence (option: parallel fence pulled out far enough that it ends before the blade) never remove the riving knife ("splitter") and check its alignment before every use of the saw needs to be exactly in line with the saw blade distance to the teeth should be about 5 mm along the entire edge make sure the parallel fence is in fact parallel do not cut several pieces on top of each other! pull the parallel fence out when cutting solid wood (Massivholz) - that way, there is room for tensions to be released after the cut (second half of the blade should stand "free")^[1] stand on the side of the machine where you can support the main part of your workpiece (usually the left) give the saw time to start up before touching the blade with your workpiece!
sawdust and small splinters can fly towards the operator	wear goggles use the dust extractor and - whenever possible - the top blade guard (sucks up dust as well!) wear a dust mask depending on the material you are cutting

Demonstration

The tutor will show you these steps in detail:

show & explain the nearest amputate bag
how to connect the dust extraction
how to use "Fritz & Franz" and the Besäumniederhalter
how to set up fence(s) on the sliding table
how to set up the parallel fence
- always has to end in front of the blade when fixing a board on the sliding table!
how to adjust blade height and angle (if angle is changed: return to exactly 90° by means of a square or inclinometer!)
- TODO: figure out whether/how angle locking screw can do anything...
how to turn on the machine
how to use the emergency stops
perform practice cut(s)
how to clean the machine after your work is done

Waiting List

This introduction takes longer than many others and usually can't be done spontaneously during regular opening times. If you would like to receive it, please add yourself to >> this list << and we will find a good time once a few members are on it!
