Tool Change; Adjustment Operation - stayer SN1435B Operating Instructions Manual

3. OPERATING INSTRUCTIONS
PLACEMENT AND TESTS
Install the machine on a flat surface. Fasten the machine
by means of 3 or 4 bolts fitted in holes 32 of the machine
base.
Ensure blade 6 is tightened sufficiently for it to penetrate
without swaying on the piece to be cut. Tighten tensor 2 if
this is not so. Perform a trial on a piece to be discarded.
Press general switch 15 into position "I" (Note: only in
models SN1435B-SN1735), in such a way the machine is
ready to operate.
Mounting the SN 180
Assemble the bench using the diagram (see FIG. A) as a
guide, joining the parts together with the supplied M8x16
screws.
(See FIG. B): Use the 4 M10X30 screws provided by
inserting the supplied packing grommets.
Cutting Arm Recovery Spring Bracket Mount: Refer to
(FIG. C) using two supplied M10x20 screws.
Cutting Operation
Ensure all the protections are complete and in
the right position before commencing each
cutting operation.
Always keep hands at a distance from the
cutting area and refrain from exposing them to the
area of exposure during cutting operations. Always
release pushbutton 18 and do not attempt to block it
between each cut (in the part placement stage).
To cut press on/off pushbutton 18 and gradually lower
saw frame 5 pressing holder 1 until placing saw blade 6 in
contact with the part to be cut. Do not force the advance
of the cut. Simply push enough to perform a clean and
efficient cut.
Only for model SN1735. To turn on press safety block
button 16 before pressing pushbutton 18.
Only for mod. SN1435B:
If the machine after a long period of use or in overload, this
means the thermal protector of the motor has intervened
to avoid any damage.
In this case, wait for a few minutes and press 15 into
position "I" and manually activate button 21.
Models SN1735 and SN1435B are provided with
electronic speed regulator 17 to adapt the work to the
cutting characteristics.
Use more moderate speeds for harder and more solid
materials. Model SN1435B has electric switch 33 to select
between 2 speeds (35m/min- 70m/min).

TOOL CHANGE

Always wear

Ensure the machine is disconnected from the mains
and that switch 15 is in position "0".
Cutting Blade Extraction
WARNING! In model SN1735 it is necessary to
previously disassemble protective casing
block 23 in order to change the blade.
- Loosen handle 19.
- Remove the front guide.
- Assemble the blade on the back guide and then the
pulleys.
- Tighten 1/2 a turn to then place the front guide and
tighten.
Cutting Blade Placement
- Choose an appropriate saw blade for the work to be
performed. HSS blades are recommended with the
number of teeth according to the thickness and type of
material. Use the table included on the machine body
to select the correct blade.
- Place saw blade 6. Place the saw blade with the teeth
in the position according to label 25. First place blade 6
between the guides and then on the pulleys.
- Tighten saw blade 6 with knob 2.
- Assemble and tighten protection cover 24 with its
screws.
Motor Brush Change (Models SN1435B-SN1735)
- Unscrew and remove brush covers 30, found on both
sides of the machine.
- Remove the brushes.
- Change the brushes for new ones (always change the
two).
- Replace covers 30 and ensure they are tightened.

ADJUSTMENT OPERATION

Speed.
As general orientation to hardness slower speed and vice
versa. A hard, stainless steel or tool will cut better at about
20m / min. A medium steel at about 29 m / min.
And soft material like aluminum, soft broek or plastic can
be cut at high speed.
Change of speed in the SN 180. It is made by changing
the position of the pulley. See (FIG D) to see the three
speeds available.
Saw Blade Tension Adjustment
The machine is provided with a saw blade tightening
device which adjusts the tension of cutting blade 6.
Ensure blade 6 is tightened sufficiently for it to penetrate
without swaying on the piece to be cut. Tighten tensor 2 if
this is not so. Perform a trial on a piece to be discarded.
Turn knob 2 clockwise to tighten the saw blade.
Model SN1470 only has two positions in control 2, up
to loosen and change the blade and down to tighten
the blade.
