Adjustment Operation - stayer SN1470 Operating Instructions Manual

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).
3.2 Tool Change
Always wear protective gloves when performing
this operation to avoid any contacts with the teeth
of the saw blade. 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.

3.3 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.
Cutting Angle Adjustment
To cut from 0° to 45°, loosen knob 22 (model SN1735 has
additional knob 20) and turn saw frame body 5 to the left
until selecting the angle desired from the scale indicated. Once
selected set the frame by tightening knob 22.
Cutting Angle Calibration
You can verify and, if necessary, adjust 0° to 45° for cutting by
using a set square between 90°and 45°. The adjustment points
are eccentric washers grub screws 34 (model SN1435B).
Cutting Depth Calibration
Turn cutting depth buffer screw 35 to obtain a full cut of the part
worked on without the blade advancing too far or damaging the
part support strip (models SN1735 and SN1470).
Blade Right Angle Calibration
Models SN1735 and SN1470 act on eccentric control 36 of the
guide rollers to obtain a totally straight cut at right angles to the
cutting surface. It is recommended an official technical service
performs this adjustment.
In model SN 180 (See FIG. E) to adjust the straight cut. Loosen
the screw L to adjust the perpendicularity by acting on the
eccentric M. Apply the Allen screws P to ensure a distance of at
least 0.3mm with the band saw.
Fixed Cut Distance Buffer Adjustment
Only applicable to model SN1735. If parts are to be cut with
the same measurements, use the cut buffer formed by parts 26,
27, 28 and 29.
Screw rod 27 in hole 9 securing it with nut 26; loosen wheel 28
and place retainer 29 at the distance necessary from saw blade
6; tighten wheel 28 once again (only mod. SN1735).
