General rules
If the machine is to be permanently demolished and/or scrapped, divide the material to be disposed of according to type and com­position, as follows:
1) Cast iron or ferrous materials, composed of secondary raw materials, so they may be taken to an iron foundry for re-smelting after having removed the contents (classified in point 3);
2) electrical components, including the cable and electronic ma­terial (magnetic cards, etc.), fall within the category of mate­rial classified as being assimilable to urban waste accord­ing to the laws of the European community, so they may be set aside for collection by the public waste disposal service;
3) old mineral and synthetic and/or mixed oils, emulsified oils and greases are special refuse, so they must be collected, transported and subsequently disposed of by the old oil dis­posal service.
NOTE:since standards and legislation concerning refuse in gen-
eral is in a state of continuous evolution and therefore subject to changes and variations, the user must keep informed of the regulations in force at the time of dispos­ing of the machine tool, as these may differ from those described above, which are to be considered as a gen­eral guide line.

THE MACHINE
7.1 - Blade tension assembly
The ideal tension of the blade is achie ved rotating the handwheel until it stops against the microswitch button ( A ). WARNING: the projection of the microswitch is f actory set during inspection, after having tightened the blade on the lengthening values indicated by its manufacturer as per specific dimensions set with the help of a special gauge. If, when replacing the b lade, the thickness and the width differ, it will be necessary to correct the projection of the microswitch. For this purpose we suggest to strictly select blades having the same features as the ones mounted originally.

Note: In case the saw is not used for a period of time, release
the blade tension to avoid useless stress. The band saw is now ready to start work, bearing in mind that the CUTTING SPEED and the TYPE of BLADE - combined with a suitable descent of the head - are of decisive importance for cutting quality and for machine performance (for further details on this topic, see below in the chapter on “Material classifica-
tion and blade selection”).
- When starting to cut with a new blade, in order to safe-
guard its life and efficiency, the first two or three cuts
must be made while exerting a slight pressure on the part,
so that the time taken to cut is about double the normal
time (see below in the chapter on “Material classification
and blade selection” in the section on
- Press the red emergency button ( 1 ) when there are condi-
tions of danger or malfunctions in general, so as to stop ma-
chine operation immediately.
Blade running-in
).
7.2 - Blade guide blocks
The blade is guided by means of adjustable pads set in place during inspection as per the thickness of the blade with mini­mum play as shown in the figure.
11
In case the blade needs to be replaced, make sure to always install 0.9 mm thick blades for which the blade guide pads have been adjusted. In the case of toothed b lades with diff erent thic k­nesses adjustment should be carried out as follows:
- Loosen nut ( C ), screw ( B ) and loosen dowel ( D ) widening the passage between the pads.
- Loosen the nuts ( H ) and the dowels ( I ) and rotate the pins ( E - G ) to widen the passage between the bearings ( F ).
- Mount the new blade, place the pad ( A ) on the blade and, loosening the dowel, allow a play of 0.04 mm for the sliding of the toothed blade; lock the relative nut and screw ( B ):
- Rotate the pins ( E - G ) until the bearings rest against the blade as indicated in the figure and then secure the dowels ( I ) and nut ( H ).
- Make sure that between the blade and the upper teeth of the pad ( L ) this is at least 0.2 - 0.3 mm of play; if necessar y, loosen the screws that fasten the blocks and adjust accord­ingly.
7.3 - Vice
- The vice can be positioned either to the right or to the left of the blade. Tight Lever ( 2 ) after positioning the vice to the far right/left. The vice can slide very quickly by meand of the handle ( 1 ); in case the the vice moves too loose along the guide, tight the screws ( 3 ).
- Approach the vice jaw allowing 3-4 mm clearance between jaw and material.

7.4 - Saw frame lowering control device
It is an accessory, ideal for the cutting of thin or STAINLESS STEEL section bars, that determines a constant lowering and consequently a good efficiency of the blade throughout the work phase. By adjusting the ring nut on the base ( 9 ), this device can be accommodated to the different situations and applica­tions. Defectiveness in the control of the low ering may be caused by the drop in braking power of the device due to the long-term blow-by of the braking fluid. Push rod (2) back into its seat and loosen plug (3). Use recom­mended oil to top up oil tank (4) with the help of a syringe-type pump. Bleed air, after ha ving tightened plug (3) and loosen screw (5) lightly until a little oil drip out; when this has been com­pleted, secure the screw. Use SHELL HYDRAULIC OIL 32 or similar.
11
7.6 - Blade cleaning brush
It is an ideal accessory for the cleaning of the blade during the cutting cycle. P eriodically chec k the condition of the brush and if necessary proceed to further adjustment to ensure cleaning of the blade.
12
BEFORE PERFORMING THE FOLLOWING OPERATIONS, THE ELECTRIC POWER SUPPLY AND THE POWER CABLE MUST BE COMPLETELY DISCONNECTED.
7.7 - Changing the blade
To change the blade:
- Lift the saw frame.
- Loosen the blade with the handwheel, remove the mobile blade-guard cover, open the flywheel guards and remove the old blade from the flywheels and the blade guide blocks.
- Assemble the new blade by placing it first between the pads and then on the race of the flywheels, paying particular atten­tion to the cutting direction of the teeth.
- Tension the blade and make sure it perfectly fits inside the seat of the flywheels.
- Assemble the mobile blade-guide enf the flywheel guard and fasten it with the relative knobs. Check that the safety microswitch is activated otherwise when electric connection will be restored the machine will not start.
WARNING: always assemble blades having dimensions speci-
fied in this manual and for which the blade guide heads have be set: otherwise, see chapter on “De­scription of the operating cycle” in the section Start­ing-up.

CHOICE OF TOOL
Since the aim is to obtain excellent cutting quality, the vari­ous parameters such as hardness of the material, shape and thickness, transverse cutting section of the par t to be cut, selection of the type of cutting blade, cutting speed and control of saw frame lowering.These specifi­cations must therefore be harmoniously combined in a sin­gle operating condition according to practical considerations and common sense, so as to achieve an optimum condition that does not require countless operations to prepare the machine when there are many variations in the job to be performed.The various problems that crop up from time to time will be solved more easily if the operator has a good knoledge of these specifications. WE THEREFORE RECOMMEND YOU TO ALWAYS USE GENUINE SP ARE BLADES THAT GUARANTEE SUPERIOR QUALITY AND PERFORMANCE.
9.1 - Definition of materials
The table at the foot of the page lists the characteristics of the materials to be cut, so as to choose the right tool to use.
words, the number of teeth per inch (25,4 mm) suitable for thematerial to be cut, according to these criteria:
- parts with a thin and/or variable section such as profiles, pipes and plate, need close toothing, so that the number of teeth used simultaneously in cutting is from 3 to 6;
- parts with large transverse sections and solid sections need widely spaced toothing to allow for the greater volume of the shavings and better tooth penetration;
- parts made of soft material or plastic (light alloys, mild bronze, teflon, wood, etc.) also require widely spaced toothing;
- pieces cut in bundles require combo tooth design.
9.3 - Teeth pitch
As already stated, this depends on the following factors:
- hardness of the material
- dimensions of the section
- thickness of the wall.

9.4 - Cutting and advance speed
The cutting speed (m/min) and the advance speed (cm2/min = area travelled by the disk teeth when removing shavings) are limited by the development of heat close to the tips of the teeth.
- The cutting speed is subordinate to the resistance of the ma­terial (R = N/mm sions of the widest section.
- Too high an advance speed (= lowering of the saw frame) tends to cause the disk to deviate from the ideal cutting path, producing non rectilinear cuts on both the vertical and the horizontal plane.
The best combination of these two parameters can be seen directly examining the chips.

9.7 - Blade type
They differ essentially in their constructive characteristics, such as:
- shape and cutting angle of tooth
- pitch
- set
Shape and angle of tooth
REGULAR TOO TH: 0° rake and constant pitch.
Most common form for transversal or inclined cutting of solid small and average cross-sections or pipes, in laminated mild steel and grey iron or general metal.
POSITIVE RAKE TOOTH: 9° - 10° positive rake and constant pitch. positive
Long spiral-shaped chips indicate ideal cutting.
Very fine or pulverized chips indicate lack of feed and/or cutting pressure.
Thick and/or blue chips indicate overload of the blade.
9.5 - Blade running-in
When cutting for the first time, it is good practice to run in the tool making a series of cuts at a low advance speed

Particular use for crosswise or inclined cuts in solid sections or large pipes, but above all harder materials (highly alloyed and stainless steels, special bronze and forge pig).
COMBO TOO TH: pitch varies between teeth and consequently varying teeth size and varying gullet depths. Pitch varies be­tween teeth which ensures a smoother, quieter cut and longer blade life owing to the lack of vibration.

Another advantage offered in the use of this type of blade in the fact that with an only blade it is possible to cut a wide range of different materials in size and type.
COMBO TOO TH: 9° - 10° positive rake. positive
9.6 - Blade structure
Bi-metal blades are the most commonly used. They consist in a silicon-steel blade backing with electron beam or laser welded high speed steel (HHS) cutting edge. The type of stocks are classified in M2, M42, M51 and differ from each other because of their major hardness due to the increasing percentage of Cobalt (Co) and molybdenum (Mo) contained in the metal alloy.
This type of blade is the most suitable for the cutting of section bars and large and thick pipes as well as for the cutting of solid bars at maximum machine capacity. Available pitches: 3-4/4-6.

FAULT PROBABLE CAUSE REMEDY
TOOTH BREAKAGE
Too fast advance
Wrong cutting speed
Wrong tooth pitch
Chips sticking onto teeth and in the gullets or material that gums
Defects on the material or material too hard
Ineffective gripping of the part in the vice
The blade gets stuck in the material
Starting cut on sharp or irregular sec­tion bars
Poor quality blade Previously broken tooth left in the cut Cutting resumed on a groove made
previously Vibrations Wrong tooth pitch or shape
Insufficient lubricating refrigerant or wrong emulsion
Teeth positioned in the direction op­posite the cutting direction
Decrease advance, exerting less cutting pressure. Adjust the braking device.
Change speed and/or type of blade. See chapter on “Material classification and blade selection”, in the section
Blade selection table according to cutting and feed speed.
Choose a suitable blade. See Chapter
“Material classification and blade se­lection”.
Check for clogging of cooling liquid drain holes on the blade-guide blocks and that flow is plentiful in order to facilitate the removal of chips from the blade.
Material surfaces can be oxidised or cov­ered with impurities making them, at the beginning of the cut, harder that the blade itself, or have hardened areas or inclu­sions inside the section due to produc­tive agents used such as casting sand, welding wastes, etc. Avoid cutting these materials or in any case perform cutting with extreme care, cleaning and remov­ing such impurities as quickly as possi­ble.
Check the gripping of the part.
Reduce feed and exert less cutting pres­sure.
Pay more attention when you start cut­ting.
Use a superior quality blade. Accurately remove all the parts left in. Make the cut elsewhere, turning the part.
Check gripping of the part. Replace blade with a more suitable one.
See “Material classification and blade selection” in the Adjust blade guide pads.
Check level of liquid in the tank. Increase the flow of lubricating refrigerant, check­ing that the hole and the liquid outlet pipe are not blocked. Check the emulsion percentage.
Turn teeth in correct direction.

BLADE BREAKAGE
Faulty welding of blade
Too fast advance
Wrong cutting speed
Wrong tooth pitch
Ineffective gripping of the part in the vice
Blade touching material at beginning of cut
The welding of the blade is of utmost im­portance. The meeting surfaces must perfectly match and once they are welded they must have no inclusions or bubbles; the welded part must be perfectly smooth and even. They must be evenly thick and have no bulges that can cause dents or instant breakage when sliding between the blade guide pads.
Decrease advance, exerting less cutting pressure. Adjust the braking device.
Change speed and/or type of blade. See chapter on “Material classification and blade selection”, in the section
Blade selection table according to cutting and feed speed.
Choose a suitable blade. See Chapter
“Material classification and blade se­lection”.
Check the gripping of the part.
At the beginning of the cutting process, never lower the saw frame before start­ing the blade motor.

FAULT PROBABLE CAUSE REMEDY
STREAKED OR ETCHED BANDS
Blade guide pads not regulated or dirty because of lack of maintenance
Blade guide block too far from mate­rial to be cut
Improper position of blade on fly­wheels
Insufficient lubricating refrigerant or wrong emulsion
Damaged or chipped blade guide pads
Tight or slackened blade guide bear­ings
Check distance between pads (see “Ma- chine adjustments” in the
Blocks
section): extremely accurate guid­ing may cause cracks and breakage of the tooth. Clean carefully.
Approach head as near as possible to material to be cut so that only the blade section employed in the cut is free, this will prevent deflections that would exces­sively stress the blade.
The back of blade rubs against the sup­port due to deformed or poorly welded bands (tapered), causing cracks and swelling of the back contour.
Check level of liquid in the tank. Increase the flow of lubricating refrigerant, check­ing that the hole and the liquid outlet pipe are not blocked. Check the emulsion per­centage.
Replace them.
Adjust them (see Chapter “Machine ad- justments” in

CUTS OFF THE STRAIGHT
Blade not parallel as to the counter­vice
Blade not perpendicular due to the excessive play between the guide pads and maladjustment of the blocks
Too fast advance
Blade guide block too far from mate­rial to be cut
Worn out blade Wrong tooth pitch
Check fastenings of the blade guide blocks as to the counter-vice so that they are not too loose and adjust blocks verti­cally; bring into line the position of the degrees and if necessary adjust the stop screws of the degree cuts.
Check and vertically re-adjust the blade guide blocks; reset proper side guide play (see Chapter “Machine adjustments” in
