This page is INCOMPLETE and still missing some important information before it can be used as a resource. Please use the "Discussion" feature above or talk to one of the tutors if you would like to help improve it. Thanks!
This is the content required for an introduction to our jointer-planer combination machine - reading this does NOT replace the mandatory session with a tutor! It will make it a lot quicker though ;-)
Let's begin! First off, make sure you have read the machine's manual (felder-gruppe.at (DE), (EN))
This is one of those machines that can cause very serious injuries when something goes wrong, so do not use if you are alone in the Space.
Safety for usage in jointer and planer mode
Additional Security when using as a jointer
Dangers | Precautions |
---|---|
rapidly revolving knives - exposed at the top: draw-in and cutting danger |
|
kickback: the jointer may grab the workpiece and throw it back to the infeed side |
|
Additional Security when using as a planer
Dangers | Precautions |
---|---|
radidly revolving knives |
|
kickback: the transport mechanism may fail and throw it out side |

Suggested Reading
Besides these safety notes, you should read <...>
Demonstration
The tutor will show you these steps in detail.
Machine preparation
- Check yourself for anything that might be catched in the machine - jewellery, cables, sleeves, hair, ...
- Check that the surroundings of the machine are clear of debris and no one is in danger of being hit by a kickback
- switch to jointer mode, if it's currently in planer mode - cf. manual: 8.8
Planning the joint
- check for
1) Identify the wood grain for the proper feed direction 2) Choose the correct large face for the first planing (the hollow / concave side, not the arched / convex side) - mark side as 1) 3) Choose one of the connected smaller sides to make 90° to side 1) in the same way - mark as side 2) 4) The side opposed to side 2) is side 3) - this side will be made parallel on the Table_Saw:table saw (for more rectangular parts like boards) or by planing (for square-shaped parts) 5) Last, the side opposite to side 1) is side 4 and will be made parallel by planing
So, the correct order is: (1) large face, (2) 90° of first small face, (3) parallelize the second small face, (4) parallelize the second large face
(1) Plane the first large face
- adjust the jointer chipload (Spanabnahme) to 1mm - manual: 8.2
- adjusting the jointer blade guard (Brückenschutz/Schutzbrücke)
- the guard should be covering the full width of the blade and just above the workpiece
- stand centered, ensure no one is in risk of getting hit by kickback, activate machine
- workpiece is moved with even pressure over the table, hands slide over the guard and "walk" on the outfeed table
- check face and repeat until plane
- cf. manual: 9.4.4 & 9.4.5
(2) Straighten a small face
- check the fence for 90° against the table - cf. manual 8.4
- adjust the guard to be directly on the table (no height)
- adjust the guard to leave a small gap for the workpiece to ride through
- stand centered, ensure no one is in risk of getting hit by kickback, activate machine
- workpiece is moved with even pressure over the table, pressure against the fence and downwards on the table - fingers together, hands way clear of the blades
- cf. manual: 9.4.6
(3) Parallelize the second small face
If your workpiece is more rectangular-shaped than square-shaped, you SHOULD use the Table_Saw:table saw instead of the planer. The Table_Saw:table saw is much quicker, you can adjust the width to the desired measurement (without creating tons of wood dust), it's much cleaner (because the suction does not work when the planed edge is too small and the table is too far away).
The planer also has a maximum height of ???cm - if your workpiece is broader, you MUST use the table saw instead.
- switch machine to planer mode - cf. manual: 8.7
- measure the wood piece's width broadest point
- adjust the table height to the measured width (open table lock, use wheel to adjust height, close lock) - cf. manual: 8.5
- activate the transport, if necessary
- stand beside the planer infeed, ensure no one is in risk of getting hit by kickback, activate machine
- push the workpiece in, until it's gripped from the transport - let go and move to the other side and take over the workpiece. Stay clear of the jointer system with your hands at all times!
- lower the height by <=3mm for smaller faces and <=1mm for larger faces
- repeat, until the side is flat
(4) Parallelize the second large face
Repeat everything as seen in the third step for the last side - remember to take off <=1mm in each pass.
(5) Cleanup
- clean the whole machine and surroundings from wood splinters and dust
- check the vacuum: if the bag is more than 2/3 full, replace vacuum bag. Close full bag with tape and move to the central blue box for wood collection.
Advanced Usage / topics
- adjusting the jointer Fuge - manual: 8.3
- rarely needed! return to original (described) setting if altered?
- a very slight Hohlfuge is desirable for many glue-ups: you'll need fewer clamps and the ends of your boards will always connect in a panel [1]
- to test the result: let two jointed boards face each other - you will thus amplify the extent of curve (x2) to make it more visible [2]
- angling two sides to another angle than 90°
