3. MOVING AND TRANSPORTING OF MACHINE
The machine is transported packed (wooden crate – figure 1). For transport: upright
position or set down on the back side (control panel upwards).
"!
figure 1 figure 2
For unpacking, remove the frontal panel and the wooden blocking pieces. On the back side
(figure 2) there is a ring ( ring W, figure 2) for transporting the machine. The shape of the
machine itself guarantees sufficient stability. The base of the machine has four holes, so that
it can be fixed to the floor. We therefore advice you to constrain the machine to the floor using
expansion bolts.
Back side description
W Ring for transporting the machine without packing
Z Housing of height adjustable rod for rolls
X Main switch (yellow - red)
Insert the rod with the rolls in its vertical place (Zfigure 2) on the back side of the machine.
Move the rolls so that they can keep in place the ring of the blade during setting and
sharpening operations. Block the lower end of the support using the bolts that you can find in
the housing. Each roll is used for a specific operation (figure 3, page 6).

IMPORTANT!
The ro ll for S ETTI NG mus t be
positioned 3-4 cm. from the horizontal
rod. The roll for SHARPENING must be
positioned 15-20 cm from the horizontal
rod (Figure A).

5. ELECTRICAL CONNECTION*
The machine is equipped with plug CE and must be connected with a three-phase network**
(380V): this is written on the label on the back side of the machine (see fig. 4). Only the earth
cable can be connected with the yellow-green cable in the middle (earthing).

Note
* The machine can work also with 220V three-phase. In this case you must modify the configuration of the
clamp set. This change can be demanded at the moment of the order.
** On request, the machine can be prearranged for being connected with a single-phase network (220V).

We do not assume any responsability in case of a wrong electric connection that may
cause not only a bad performance of the machine, but also damages to people,
animals, things.
6. INSTRUCTION FOR USE THE MACHINE
STARTING UP
Rotate the main switch (switch X, fig. 2, page 5) on the electrical switchboard located on the
back side of the base: the lamp P (fig. 21, page 15) placed on the switchboard will light up
indicating that the machine is ready to be used.

Set up sequence:
Pay attention when handling the blade during its installation : it is necessary
to be very careful in order to avoid being hurt. It is necessary to wear work
gloves to protect the operator from hurting himself with the teeth of the saw.
-Hang the blade on the left roll with the back of the blade turned towards the back part
of the machine, the teeth turned towards the front part and the cutters towards the
floor.
-The result of the following operations can be checked rotating by hand the handwheel,
observing the motion of the setter.
- Open the device Uused for pressing the blade (fig. 7, page 10). Rotate the
handwheel Itill the little hammers M1 and M2 reach the maximum opening
(see under here).
figure 8!

C/Casanova, 1 - 08782 St. Joan Samora – Tel: [phone] – Fax: [phone] - + [email protected]
MAXIMUM OPENING

-Open the jaws of the vice and press the two little cylinders Tof the setting device,
using your fingers (fig. 7, page 10).
!figure 9
-Adjust the height of the blade sliding support (screw O, fig. 7, page 10), so that only
the tooth profile protrudes entirely from the jaws of the vice. Close the plate U(fig. 7,
page 10) on the teeth of the blade. Pressing the blade against the support, the plate
guarantees a right operation. At the same time the blade can slide well (fig. 10).
"figure 10
-Position correctly the tooth pusher R(fig. 7, page 10). It must push only one tooth at a
time.
IMPORTANT: The perfect pushing action of the tooth pusher is very important: the
whole setting operation depends on it.
-Adjust the blade feeding (adjusting screw Q, fig. 7, page 10) in conformity with the
pitch of the teeth and the type of setting. The tips of the teeth must reach the same
trajectory of the little hammers. !

"figure 11
-Adjust the quantity of setting using the adjusting screw (screw S, fig. 7, page 10)
changing the race between the two little hammers (right and left) that move alternately
but symmetrically, moving at the same speed. Increase or decrease the travel of the
two little hammers (right and left) according to your needs. You can also modify the
length of the little hammers M1 and M2 using the adjusting nut (fig. 7, page 10).
"

-Rotate the handwheel I(fig. 7, page 10) and observe the result that you have
obtained. If you do not obtain a good result, repeat the operation changing values.

TYPE OF SETTING
This setter can perform two types of setting:
"
figure 13
The machine is always preset for type of setting.
➢To pass from type of setting A to type of setting B:
-Looking at the setter from the front: on the right side there is a cam between the setter
and the reduction gear. Loosen the clamping bolt of the bearing and move the tooth
pusher arm towards the reduction body and screw the clamping screw.

BODY

Result of this operation: the bearing that is on the tooth pusher arm moves on the portion of
the cam having only two tips: the setting will turn into type B (teeth bended left/right).

➢Back to type of setting A:
-Starting from the cam between the setter and the reduction gear, loosen the clamping
screw and press the tooth pusher arm towards the setter body.

Result of this operation: the bearing that is on the tooth pusher arm moves on the portion
of the cam having three tips: the setting will turn back into type A (teeth bended right/left/
straight).!
