Before starting the machine, check with a phase-meter to know if the phases order is correct, looking from left to right, at the tension inlet of the regulator. A practical way to carry out this checking if a phase-meter is not available is as follows:
Check that the spindle rotation direction coincides with the corresponding position of motor rotation selector. If the rotation direction does not coincide, the connection has not been correctly effected and it will be necessary to interchange 2 of the 3 phases of the connection.
When cleaning the machine the following products should not be used: benzene, toluene or acetone.

1 - INSTALLATION
Necessary space and foundation. Foresee the space necessary according to drawing page 13. Prepare a cement base according to drawing page 12. Such base must be vibration-proof and if it is possible isolated from the exterior.
Machine unloading. In order to realise the unloading of the machine, a 50 mm. Steel bar will be used as it is shown on
drawing page 11, protecting machine parts that can be damaged by the slings with a cloth. Then, machine balance will be checked, correcting if necessary the slings position to achieve it, proceeding to the unloading of the machine with due precautions, specially at the moment of touching the machine base with the ground, so that this contact
and later settlement is done gently and without collision.
lnstallation on foundation and leveling. Place machine on cement base and mark its position on base through machine anchoring holes. Get off the machine then, and proceed to open the holes on base according to the marked position and to the drawing page 12. Afterwards, place the machine on the base together with the anchoring screws, plates and leveling screws, levelling out the machine as well as possible and fill base holes with a concrete mixture.
When concrete is hard enough, proceed to definite levelling and once this is done tighten anchoring nuts strongly.
Cleaning and lubrication. Once de above operations have been done, clean machine carefully removing the antirust grease which protects it, by means of petroleum and cloths, bearing in mind the VERY IMPORTANT WARNING about the cleaning see page 2.
Lubricate machine see page 141, checking machine oil levels.
Electric connection.
1. A connection with an adequate cable section for the total comsumption of electricity of the machine should be prepared, placing between the mains and the machine at least some fuses, being preferable to use a switch with fuses.
2. Open the cabinet, to connect the connection in the general switch, once the connection is made, close the cabinet door and operate the general switch, in such a way that the switch handle be placed on position 1.
3. Proceed to check if the different machine elements work correctly, having in mind the VERY IMPORTANT WARNING
about the connection see page 2.
If the machine have automatic lubrication equipment, press the lubrication button and check if the manometer is pressurized and works.
If we see that there is no pressure, we shall disconnect the general switch from the machine, and also that one of the connection and we shall proceed to change two of the three inlet phases. Once this done, we shall do the same test and we shall check if we have pressure to effect the lubrication.
11 - STARTING
Once the machine is ready and the oil levels have been checked, proceed to the starting according to the following points:
a Loosen all blocking points.
b Connect intake current switch.
c Lubricate frame guides, knee and table, pushing the corresponding lubrication control.
d In case of starting spindle head, place inverses switch on position 1 or 2, according to the wanted rotation direction.
e Operate push-button corresponding to wanted movement.
lmportant warnings. Before starting, make sure all oil levels are on the half point of correspondent oil sight. Operate the lubrication drive on different positions of table, knee and ram. Machine is supplied with an alarm system in the event that it has automatic lubrication. This alarm is automatically connected when there is not oil left at all, in the lubrication. To stop the alarm, general stop push-button should be operated. When feed drive motor starts, without the automatic lubrication tank having been previously filled up, alarm will ring again. Keep daily attention to level of such lubricating group. Trial period operation is very important for the life and good working of the machine. For the first 150 hours of work, use low speeds, are not to be passed.
Machine is provided of two ammeters, which show speeds motor current drain and feeds motor, respectively. In no case, the needle should pass the red mark on the ammeter.
Speed mechanism is provided with an electromagnetic brake that can be operated by the correspondent push-button. Its duty is to facilitate a quick stop of the spindle on special or emergency events. To operate spindle stop, machine general stop must be used, having the precaution of stopping feeds first by the feeds stop push-button. This operation must be done specially on a hight feed, or working with rapid displacements. In order to get the rapid traverse, it will be enough to operate rapid push-button and while we hold it pushed, displacement selected before will work on rapid. On stopping pushing, such displacement will go back to the previously selected feed. It is advisable not to abuse of rapid displacements for the first 300 hours of work. Guideways will be runned in only after 300 hours of work on all their length.
111 - MACHINE CONTROLS
Push-buttons and handwheels. The machines have a control pannel, on the front of the machine or on pendant control. Handwheels for manual displacements of machine, provided of corresponding graduated drums, are exactly double and they are placed on the front and left side of the machine. The AM model have only one set of handwheels on the front of the machine.
Brake vertical traverse. Zayer BM machines, except for AM model, are provided of ball-screw in the vertical traverse, which due to its rare friction tents go down a little because of the knee and table weights. In order to avoid this phenomenon such ball-screw has been fitted in a brake that acts on the screw to prevent it going down. This brake comes out from factory already regulated, however, if it would be necessary to increase the ball-screw brake, it
would be operated as follows. The vertical traverse handwheel, is situated on the machine front and it has on its center the regulating control of brake tension; to increase this tension, nut has to be loosen, turning to the right the pin in which such nut is placed and tension will be increased. After this operation, proceed to tighten nut.
Clamping mechanism. Machine is provided with clamps on the three movements. It is very important to check before operating any of the traverses, wheathel the corresponding clamps are on or not. Clamps for cross traverse are placed on top left part of frame and they are operated by two levers. Table clamping is done by the levers placed on front of the knee top. Vertical traverse clamping is done by two side levers placed on the knee back part or on the front bottom part; this is on the BM models. In these models, the levers operate blocks which hold bracket to front supports and the former to machine frame tails, with a safety device which impedes the displacement if the levers are blocked.
Speeds change. They are done by the relative position of three levers, situated on the ram left side. Feeds are selected according to the table placed near the change controls. When trying to make a change of speeds, it will be done with motor stopped, a slight resistance of lever to go into its position will be noticed. It will be enough to operate instantaneously speds intermítent push-button, so that corresponding motor will turn in order to make easier the introduction of one gear into the other, and so, a change of speed will be achieved. Head positions. By combining head and elbow rotation, the wanted inclination of the milling arbor can be obtained. In order to do these rotations, it is necessary to losen slightly fixing nuts and take out positionning pins between ram and elbow and between the former and the head. Then, by introducing lever provided with the machine into corresponding head or elbow
holes proceed to give the wanted position according to the tabulation enclosed in this instructions book. Before the operations mentioned above, it will be necessary to check wheather speeds drive motor is stopped. Once wanted position has been obtained, fixing nuts will be tighten again.
Usual positions. The usual milling positions are:
Spindle іn a vertical position.
Spindle in a low horizontal position.
Both positions are given by conical pins, which insures the situation of the head-elbow assembly. Special care must be taken in cleaning thoroughly these pins and introducing them, after placing head and elbow in correct position with the help of the vernier. Any swarf on the pins or the fact of knocking on the pins when the respective hole are not in line, can bring as a consequence the loosing of the exact position, and so, defects of machine verification. After introducing pins manually by means of the oscillation to both sides of head or elbow and after being pin wholy introduced and positioned, strike slightly such pin with a
plastic hammer in order to get an exact nailing of the wanted position. It is necessary to notice, that pins are provided of an extraction nut, which must be placed on pin in the wanted posítion before proceeding to the introduction of the pin.
1V - MAINTENANCE
Apart from following the instructions and recommendations already mentionned, it is necessary to study each case, the best arrangement of the part on the machine, avoiding that the biggest cutting or weight efforts of the part, if this is a large one, act or gravitate on the table parts which do not coincide with the machine central part or are off-center on its traverse trying so that the biggest efforts of cutting are done with the ram in a backwards position and they are not done in its most forward position.
It has special importance to lubricate periodically as it is shown on page 14, as well as to check the levels and oiling sights. Doing a regular cleaning of the machine avoids blocking of lubricating conveyors, it keeps its mobile parts without scratches or seizings and shows the workers neatness and order. Motorized ram and universaI head. Such elements need special attention for being machine parts of a great importance. The life of these parts is remarkably proionged with a rational lubrication of these assemblies. It is advisable to drain and clean motorized ram every two months renewing oil according to the type shown on page 16. Spindle head bevel gears must be lubricated approx. every 15 days. The quantity of lubricating grease will not be excessive one or two strokes. Keeping this advise frequent lubrication and small quantity of grease, is very important to get a good efficiency of the head.
The spindle head bearings must be lubricated every 200 working hours.
KLÜBER ISOFLEX NBU-15 is the only type of lubricating grease to be used in the planetary head. To get an efficient lubrication of the two conical gears in the planetary mobile-spindle, it will be necessary to disassembly the head monthly, in order to impregnate such above conicals gears with KLUBER ISOFLEX NBU-15 grease.

Esta posición de1 eje cabeza1 es adecuada para efectuar chaflanes de ángulo de inclinación H igual en dos caras de 1a pieza perpendiculares entre sí, mediante 1os
desplazamíentos longitudínal y transversal.
La forma de operar es 1a siguiente:
1 Conocido e1 ángulo H deseado obtendremos e1 ángulo H1 intermediario sobre 1as tablas.
2 Una vez conocido dicho ángulo intermediario H1 procederemos como en 1os demás casos a hallar 1os grados correspondíentes de 1os nonios a y Ь mediante

Milling arbor must be placed on a bisector plane of A, B, C, D and E, B, C, F planes.
This posítion of spindle axis is adequate for doing bevels of an angIe of inclination H equal in two sides of the piece perpendicular between them, by longitudinal
and cross displacements.
The operating way is as follows:
1. Known the angle H wanted, we wi11 get the intermediate angle H1 on the tabulation.
2, Oпce known such intermediate angle H1, we wi11 proceed, as in the rest of the cases, to find the correspondent degrees of vernier a and b Ьy interpolation of
H1 value over H columп.
3. 1t must Ьe added or subtracted to vernier a value of degrees, the 90 H value.
4. We wi11 proceed to put head according to degrees shown for our case on column b and the elbow according to the resultant degrees of a+ 90 H oг a
90 H .
Example:
For H= we have a va1ue H1 = 71 07 oп the tabulation. 0n column H, we get by interpolation a and b values correspondent to 71 07 and which result respec-
tívely a= 315 38 ; Ь= 110 39 for spindle axis to the left inclined downwards and a= 440 22 ; Ь= 249 21 for spindle axis to the right downwards inclined.

- Generai aplication of fourth case; oп this one, the angles over piece faces are perpendicular between them, they are unequal.
The operatíng way ís as follows:
1 We wi11 get intermediate angle H1 by formula
tg 1
tg H1 =
sen H
21 We wí11 proceed to get the degrees values for a and b verniers on a similar way as fourth case keeping in mind, that to posítíon elbow to a va1ue gíven on
tabulation, it must be added or subtracted to ít the 90 H value.
3 Example:
For H= 80 1= 600
tg 60
tg H1 =
sen 80
H1 = 60 22
0n column H1, we get by interpolation a and b values correspondent to 60 22 and which result respectívely a= 305 34 ; b= 90 38 for spíndle axis to the left
downwards ínclined and a= 540 26 ; Ь = 269 22 for spindle axis to the right downwards ínclined.
a values wí11 be: solutíons:
305 34 + 90 -80 =315 34 1. a= 315 34 Ь= 900 38 Spíndle axís to the left
305 34 90 800 = 295 34 2. a= 295 34 Ь= 90 38 downwards inc1ined
54 26 + 90 80 = 64 26 3. a= 64 26 Ь= 269 22 Spíndle axis co the ríght
54 26 190 80 = 440 26 4. a= 440 26 Ь= 269 22 downwards inclined
Aplication générale du quatríème cas; dans ce cas 1es angles dans 1es faces de 1a pièce perpendiculaíres entre eux, ne sont pas égaux.
La manière d opéгeг est 1a suívante:
1 Oп calculé 1a valeur de 1 angle intermediaire H1 par 1a formule:
tg 1
tg H1 =
sen H
21 On pгocède a trouver 1es valeurs de degrés pour 1es verniers a et b de maпіèГe simílaire au quatríème cas, compte tenu que pour positíoner 1e coude i1 faut
ajouter a 1a va1ue a donпée dans 1e tableau 1a valuer 90 H
3 Exemple:
Pour H= 80 1= 60
tg 60
tg H1 =
sen 80
H1 = 60 22
Paг interpolatíon dans 1a colono e H1 on obtient 1es valeurs de a et b qui correspondent a 600 22 et quí resultent a= 305 34 ; Ь= 90 38 pour axe de broche à
gauche vers 1e bas, et a= 54 26 ; Ь = 269 22 pour axe de broche á droite vers 1e bas.
Les valeurs de a seront: Solutions:
305 34 + 90 80 = 315 34 1. a= 315 34 Ь= 90 38 Axe de broche à gauche
305 34 90 80 = 295 34 2. a= 295 34 Ь= 90 38 vers 1e bas
54 26 + 90 -80 = 64 26 3. a= 64 26 Ь= 269 22 Axe de broche à droite
540 26 90 80 = 440 26 4. a= 44 26 Ь= 269 22 ver 1e bas
Die Neigungswinkel H und 1 über den zwei winkelgerechten Seiten des Teiles sind ungleich. Die Anwendung ist in allgemeinen wie bei dem vierten Fa11.
Es wird wíe folget vorgegangen:
1 Der Zwíschenwínkel H1 wird durch folgende Formel errechnet:
tg 1
tg H1 =
sen H
21 Nach Ermíttlung des zwischenwinkels H1 werden die zugehiíτígen Wınkel des Noníuses a und b ähnlich wie bei dem vierten Fa11 errechnet. Es so11 dabeí de-
rűcksíchtig werden, um das Zwíschen-Gelenkstück eínzustellen muss der Wert 90 H zu dem Wert a іπ den Tafe1 angegeben, addiert oder subtrahiert
werden.
Beíspíel:
H = 80 ; 1 = 60
tg 60
tg H1 =
sen 80
H1 = 60 22
Auf Spalte H1 errechnet man durch InterpoIation den zugehőrigen Wert von 60 22. Diese engeben a = 305 34 und b= 90 38 wenn die Fräskopfspindel links
nach unten verdreht íst, bzw a =4 26 und b = 269 22 wenn die Fräśkopfspiпdel rechts nach unten verdreht ist.
Díe Werte werden dann: . Líisungen:
305 34 + 90 80 = 315 34 1. a= 315 34 Ь= 90 38 Die Fräskopfspindel steht links
Iι 305 34 90 80 = 295 34 2. a= 295 34 Ь= 90 38 nach unten verdreht
54 26 + 90 80 = 64 26 3. a= 64 26 Ь= 269 22 Dıe Fräskopfspındel steht rechts
540 26 90 80 = 44 26 4. a= 440 26 6= 269 22 nach unten verdreht
