Proxxon KG 50, Manual

4. Before starting work:
For safety reasons, the Proxxon KG 50 capping device comes
delivered with a cardboard disk instead of a cutting disk. That
means you need to install the cutting disk yourself, which is easily
done. 5-each cutting disks are supplied in the scope of delivery of
the device. Furthermore, after having used the device for a long
time, replacing the cutting disk may become necessary if the old
one is too worn. The procedure for replacement is the same and
is described as follows:
4.1. Installing or replacing the cutting blade
Please note: You can acquire replacement-cutting blades for the
machine in businesses under the no. 28 152!
Caution:
You must pull the mains plug before installation!
1. Unscrew fastening screw 1 (see fig. 2) from the yellow pro-
tective cover 2 and pull up the cover.
2. Lock shaft-1 (fig. 3) in place by pressing stopper 2. To do
that, you need to turn the shaft a bit to find the corresponding
notching position
3. Remove fastening screw 3 and remove washer 4. Watch out
for flat washer 5.
4. Put on the new cutting disk
Caution!
The ceramic-bonded cutting disk is very sensitive to being bent.
Do not take hold of the disk to remove or pull the fastening screw.
The disk is very fragile.
Make sure that cutting disk 4 is correctly seated!
5. Reassemble by simply using the reverse sequence.
5. Working with the capping device
Note:
Safe and precise work is only possible if the device has been cor-
rectly fastened to a tabletop. This can be done with the enclosed
C-clamp (shown in fig. 1), or with the help of screws. Bores (13,
fig. 1) are available in the footplate.
Caution:
Make sure you always pull the plug before fixating or transporting
the device!
Danger!
Never operate the capping device without the yellow protective
cover and safety glasses!
The red safety lever (Fig. 1, pos. 3) must always be folded comple-
tely back into the resting position as otherwise, it could slip off if the
cutting head is pushed by mistake and thus loses its blocking action.
You can start work after the device is standing on a stable support
and the cutting disk has been installed. There are no other prepa-
rations necessary and the workpiece to be cut can be
clamped into the vice and separated (fig. 4 a/b). This is how it’s
done:
5.1. If you want to make straight cuts (Fig 4a)
1. Make sure circular table 1 is in the 0° position: The lug on
black rotary table 2 must point to the 0° mark on the scale in
device foot 3. If not, please adjust it. If it is necessary to do
so, remove thumbscrew 4 and push the rotary table into the
corresponding position. Caution: the rotary table snaps-in at
0°. After that, make sure you retighten the thumbscrew.
2. Place workpiece 6 into vice 5, then align and tighten it. While
doing so, mind the desired length of the „free“ end!
3. If in doubt, after unlocking blocking lever 7 you can swivel
cutting head 9 out of the switched-off (!) device so far that
cutting blade 8 is seated on the workpiece. With this
method, you can better estimate the later length of the work-
piece.
5.2. If you want to make miter cuts (Fig 4b)
1. Loosen thumbscrew 4 and set rotary table 1 to the desired
angle. Use scale to help do this. Then retighten the stop
screw.
2. Place workpiece 6 into vice 5, then align and tighten it. While
doing so, mind the desired length of the „free“ end!
3. To do that, after unlocking blocking lever 7 you can swivel
cutting head 9 from the switched-off (!) device so far that the
cutting blade is seated on the workpiece here also. With this
method, you can better estimate the later length of the work-
piece.
5.3. Severing a workpiece
Switch the device on using on-off switch 10 and guide it down
using slight pressure on recessed grip 11 until the cutting disk
touches the workpiece. Caution:
While doing so, please actuate the red blocking lever: otherwise,
the cutting head cannot be swiveled!
Increase the pressure on the workpiece only so much that the
motor speed does not greatly decrease. That is how to sever a
workpiece.
Caution!
It is not the contact pressure but the speed that generates high
cutting power! Never use force! This unnecessarily stresses the
device’s mechanics and leads to poor results and increased wear!
Caution!
Never actuate the stopper while the device is running.
5.4. Working with the longitudinal stop (fig. 5)
The KG 50 capping device is supplied with an adjustable longitu-
dinal stop (1). This means any desired number of workpieces can
be cut to the same length. To do so, insert the workpiece to be cut
into the vice pushed up to the limit stop and then clamp it in
place. After severing the workpiece and loosening the vice, push
