Sawing; General Notes On Setting The Saw Head; Straight And Mitre Cuts; If You Would Like To Produce Straight Cuts (See Fig. 2A) - Proxxon KGS 80 Manual

Caution:
Risk of injury! Work pieces that have been clamped too short
could tear loose and fly about!
Please ensure that the work piece is always securely clamped in
the vice while you are working! Make sure you have sufficient
clamping length and sufficient work piece size! A too short clam-
ping length reduces the clamping force.

6.2 Sawing

6.2.1 General notes on setting the saw head

To achieve the shortest possible clamping length of the clamped
work piece, the position of the saw head can be adjusted by using
the knurled screw 11 (fig. 2a/b). This enables the saw blade to be
guided as close to the clamping fixture 6 as possible. Cuts will then
be especially clean and precise if there is only a small gap between
the restraint and the saw blade level.
Before every use, make certain that the saw head is not set so that
the saw blade will collide with the jaws of the clamping fixture when
swivelling the saw head down (e.g. by shutting down the saw head
when machine is off. Caution: disconnect the mains plug here)! Risk
of injury!
Caution
Do not remove any cutting scraps or other work piece parts from the
cutting area as long as the machine is running and the saw blade is
not in its home position.

6.2.2 Straight and mitre cuts

6.2.2.1 If you would like to produce straight cuts (see fig. 2a)

1. Make sure that turntable 1 (see fig. 2a) is in the 0° position: Ar-
row marking 2 must point to the 0° marking on scale 3 in the de-
vice base. If not, then please set as follows: (Caution: Please
make sure that knurled screw 13 is released!)
2. Release stop lever 4 by lifting it and guide turntable 1 to the cor-
responding position. Let go of stop lever 4. Caution! The turntable
will lock in place at 0°. If necessary, move turntable back and
forth a bit with released stop lever until the stop lever catches.
3. Insert work piece 5 in clamping fixture 6, align and tighten. Pay
attention to the desired length of the „free" end!
4. For perfect alignment, saw head 7 of the switched off (!) device
after locking lever 8 has been unlocked (pull to the front) can be
swivelled down so far that saw blade 9 at the automatic swiv-
elled-away saw blade protection 10 just barely touches the work
piece (see also fig. 3). This enables a better estimation of the fu-
ture length of the work piece.
5. For exact adjustment, saw head 7 can be finely toggled by using
knurled screw 11.
Caution!
Please make sure here that the saw blade 9 will never collide with
the jaws of clamping fixture 6!
Please note:
Crosscutting with the supplied length stop is no problem! How this
works is described in "Working with the Length Stop".
6. See fig. 3: After locking lever 8 has been released and the on/off
button 12 has been pressed, swivel saw head 7 down and cut the
work piece into two as shown in Fig. 3. The saw blade protection
swivels up.

6.2.2.2 If you would like to produce mitre cuts: (See fig. 2b):

1. Release knurled screw 13 and lift up stop lever 4. Now set
turntable 1 to the desired angle. Please use scale 3 and orient
yourself using arrow marking 2 on turntable 1. The 15° gradua-
tions are provided with serrations, and stop lever 4 must be re-
leased so that they can become effective. Intermediate settings
can also be set and fixed using knurled screw 13.
2. Insert work piece 5 in clamping fixture 6, align and tighten. Pay
attention to the desired length of the „free" end here as well!
3. For perfect alignment, saw head 7 of the switched off (!) device
after locking lever 8 has been unlocked (pull to the front) can be
swivelled down so far that saw blade 9 at the automatic swiv-
elled-away saw blade protection 10 just barely touches the work
piece (see also fig. 3). This enables a better estimation of the fu-
ture length of the work piece. For exact adjustment, the saw head
can be finely toggled by using knurled screw 11.
Caution!
Please make sure that the saw blade will never collide with the jaws
of clamping fixture 6!
Please note:
Crosscutting with the supplied length stop is no problem! How this
works is described in "Working with the Length Stop".
4. After block lever 8 has been released and the on/off button 12 has
been pressed, swivel saw head 7 down and cut the work piece
in two as shown in fig. 3. The saw blade protection swivels up.
Caution!
The rotational speed, and not the contact pressure, generates the
high cutting performance! Never work with force! This places an un-
necessary load on the machine mechanics and leads to bad results
and increased wear!

6.2.3 Working with the Length Stop (see fig. 4)

The KGS 80 crosscut and mitre saw is supplied with an adjustable
length stop 1. Any number of work pieces of equal length can be cut
off. Work piece 2 to be cut off is inserted in clamping fixture 3,
pushed up to the limit plate 4 and then clamped. After the work piece
has been cut off and the vice has been loosened, the material is
pushed up to the limit stop again, clamped with the vice and then
cut off. This can be repeated any number of times.
This is how to set the limit stop:
1. Allen screw 5 is released using an Allen key (included in deliv-
ery). Limit stop 1 can then be pushed in guide 6 up to the desired
length. Make sure that limit plate 4 is properly aligned and that
it hits the work piece correctly when "limit stopped"!
2. Clamp limit stop 1 with Allen screw 5.
If the limit stop is not required, it can be completely removed after
releasing screw 5.
The desired position of the limit stop can be determined, for exam-
ple, by appropriately marking a work piece, clamping it so that the
saw blade hits the marking exactly and then by aligning the limit stop
accordingly. This enables the exact reproduction length for the de-
sired number of the subsequent work pieces.
Caution!
After the work piece has been aligned and clamped, fold limit plate
4 away during work (see fig. 4) to prevent the separated work pieces
from jamming!
