GENERAL SAFETY NOTES
ALL INSTALLATION WORK INCLUDING THE ELECTRICAL CONNECTION MUST ONLY BE CARRIED OUT BY QUALIFIED PERSONNEL.
THE MACHINE MUST ONLY BE OPERATED BY A TECHNICALLY TRAINED AND EXPERIENCED OPERATIVE WHO IS ALSO INSTRUCTED
IN ‘SAFETY AT WORK ’ PROCEDURES.
ANY ADJUSTMENTS, CLEANING, REPAIRS OR CHANGING OF THE SAW BLADE MUST UNDER NO CIRCUMSTANCES BE PERFORMED
UNLESS THE MACHINE IS FULLY ISOLATED FROM THE ELECTRICAL POWER SUPPLY. ENSURE THE EMERGENCY STOP BUTTON ON
THE CONTROL BINNACLE IS PRESSED AND THE POWER SUPPLIES AT THE MAINS ARE DISCONNECTED.”
THE BAND SAW MUST BE REGULARLY INSPECTED AND MAINTAINED IN GOOD SERVICEABLE CONDITION. EYE PROTECTION, EAR
PROTECTION, GLOVES AND PROTECTIVE CLOTHING MUST BE WORN WHEN ANY OF THE ABOVE PROCEDURES ARE BEING CARRIED
OUT, AS WELL AS WHEN CUTTING FLUID IS PREPARED, INTRODUCED OR DISPLACED FROM THE BAND SAW MACHINE (THE
RELEVANT ENVIRONMENTAL REGULATIONS MUST BE OBSERVED IN CASE OF THE USE AND DISPOSAL OF CUTTING FLUID ETC.)
THE BAND SAW MUST BE INSTALLED ON GROUND. OBSERVE THE PERMISSIBLE FLOOR LOAD. THAN THE BAND SAW MACHINE HAS
BEEN PROPERLY BOLT TO GROUND SECURELY.
ALLOW SUFFICIENT WORKING SPACE AROUND THE BAND SAW OF AT LEAST 1 METER. INSTALLATIONS OF STOCK ROLLER
CONVEYORS REQUIRE ADDITIONAL SPACE AND POSSIBLY A LIFTING MECHANISM FOR HEAVY WORK PIECES. ALWAYS ENSURE
THAT THE WORKING AREA AROUND THE BAND SAW IS WELL LIT.
SAFETY INSTRUCTIONS
BE SURE THAT ELECTRICAL CONNECTION IS MADE CAREFULLY. TO AVOID UNWANTED SITUATIONS LIKE ELECTRICAL SHOCK,
PROTECT THE MAIN SUPPLY CABLE WITH A HOLSTER.
BEFORE RUNNING THE MACHINE, BE SURE THAT ALL OF THE PROTECTIONS ARE MOUNTED PROPERLY AND ALL THE COVERS
ARE CLOSED.
AVOID FROM SMOKE AND MOISTURE.
PLEASE USE THE PARTS AND EQUIPMENTS WHICH ARE RECOMMENDED. USAGE OF UNSUITABLE PARTS AND MATERIALS
WHICH ARE BIGGER THAN THE CAPACITY OF THE MACHINE CAN CAUSE UNWANTED SITUATIONS.
CHECK THE MACHINE AND INFORM THE DEFECTS EVERYDAY.
DON’T LEAVE ANY MATERIAL AFTER CHANCING THE BAND.
DO NOT HOLD THE MATERIAL WHILE THE MACHINE IS CUTTING. ALWAYS TIGHTEN THE MATERIAL BY USING ESSENTIAL
PARTS.
PLEASE PAY ATTENTION TO CHOOSE THE AREA OF THE MACHINE WHICH DOESN’T INCLUDE ANYTHING THAT CREATES
DIFFICULTIES TO CONTROL THE MACHINE
PLEASE BE SURE THAT THE TEETH OF THE BAND ARE LOOKING TO CORRECT DIRECTION.
DON’T LEAVE THE BAND ON THE GROUND OR ANY PLACE THAT IS DANGEROUS FOR OTHER PEOPLE.
BE CAREFUL WHEN USING THE MACHINE AND KEEP THE WORKING AREA CLEAN ( CLEAN THE SAW DUSTS AND OIL TRACES
)
PAY ATTENTION TO SECURITY INSTRUCTIONS WHEN USING THE MACHINE.
DON’T WEAR LOOSE CLOTHS WHEN USING THE MACHINE.
REGARDLESS USE THE PROTECTIVE GLOVES WHEN USING THE MACHINE.
DON’T GET CLOSE TOO MUCH TO THE MACHINE WHEN RUNNING.
BEFORE CARRYING OUT ANY CLEANING OR MAINTENANCE PROCEDURE, DISCONNECT THE MACHINE FROM MAIN SUPPLY.
IN SOME CONDITIONS, NOISE LEVEL CAN BE ABOUT 85 DB. BAND CHOICE AND CUTTING SPEED IS IMPORTANT FACTOR FOR
NOISE LEVEL.
ILLUMINATION IS AN IMPORTANT FACTOR FOR SECURITY.
RATIO OF COOLANT LIQUID IS IMPORTANT FOR OBTAINING OPTIMUM LUBRICATION.
NEVER USE THE MACHINE IF YOU NOTICE ANY FAULT OF THE MACHINE OR ABSENCE OF ANY PART OF THE MACHINE.
CONTROL THE EMERGENCY BUTTON AT LEAST ONCE A WEEK AND BE SURE THAT IT IS WORKING PROPERLY.

LIMIT SWITCH.)
7) REGULATE THE CUTTING PRESSURE BY THE THROTTINLING VALVE.
8) BECAUSE OF COUNTER, THE MACHINE COULD BE LOCKED. IN THIS SITUATION THE MACHINE DOES NOT WORK. UPPER LINE OF
COUNTER MUST BE PRESET AFTER THAT THE RESET BUTTON MUST BE PRESSED.
9) FOR THE NEXT CUTTING, FOLLOW THE SOME WAY.
AUTOMATIC CUTTING OPERATION
1.SWITCH ON THE MAIN SWITCH.
2.SEALET B6 SELECTOR TO POSITION 2.
3.ADJUST S2 LIMIT SWITCH ACCORDING TO THE MATERIALS DIAMETER OR HEIGHT.
4.PRESS B3 PUHBUTTON TO THE BOW UP.
5.SELECT B6 SELECTOR TO POSITION 1.
6.SLIDE THE LENGHT-STOP ON THE SPINDLE UNTIL REACHING REQUIRED LENGHT AND THE TIGHTEN.
7.PRESET THE NUMBER OF CUTS REQOIRED AND PRESS THE RESET BUTTON ON THE COUNTER.
8.PRESS START BUTTON THE CUTTING OPERATION.
9.REGULATE THE CUTTING PRESSURE BY THROTTING VALVE.
AFTER STARTING THE CUTTING OPERATION, YOU DO NOT NEED ANY OPERATION ELSE, BUT ACCORDING TO THE GRADE OF
METERIAL YOU SWITCH ON THE COOLANTPUMP OR NOT.
P.S. IF THE MACHINE STOPPED WITHOUT REACHING PRESET NUMBER, THE BLADE COULD BE BROKEN OR THE MATERIAL LENGHT
COULD BE SHORTENED.

CONNECTING WITH THE MAINS
THE MACHINE IS EQUIPPED WITH A DRIVE MOTOR DRIVING BY A V-BELT AND OTHER NECESSARY ELECTRICAL
EQUIPMENTS. ELECTRICAL BOX IS INSTALLED ON THE LOWER PART. CONTROL PANEL IS MOUNTED ON THE ELECTRICAL BOX. THE
MACHINE IS CONNECTED WITH THE MAINS AT THE ELECTRICAL BOX. R, S AND T STAND FOR PHASES, N STANDS FOR NEUTER AND
PE STANDS FOR GROUND.
THREE-PHASE MOTORS ALLOW AN EASY CHANGE OF THE POLES AT THE CONNECTING FLEXES IN ORDER TO CORRECT THE
DIRECTION OF CUTTING

12
BLADE GUIDANCE:
FOR AN ACCURATE GUIDANCE OF THE BAND SAW BLADE THERE ARE TWO RIGID AND PRECISE VERTICAL GUIDE ARMS FITTED
WITH ROLLERS FOR TWISTING AND CARBIDE INSERTED PLATES FOR THE FINAL AND EXACT BLADE GUIDE. ALWAYS PUT THE
BLADE GUIDE ARMS AS CLOSE AS POSSIBLE TO MATERIAL TO BE CUT AND TIGHTEN IT. THE PLAY OF THE BLADE CAN BE RESET BY
ALTERING THE POSITION OF A CARBIDE INSERTED GUIDE PLATE.
SETTING NEW BLADE
- FIRST OF ALL BOTH GUARD FLAPS AND THE GUARDS WHICH ARE ON THE GUIDE ARMS HAVE TO BE OPEN UPWARDS.
- LOOSEN THE BLADE BY THE HAND LEVEL SO FAR THAT THE BLADE CAN BE EASILY TAKEN OFF AROUND THE PULLEYS.
- THE SAME WAY BUT VIC AVERSE, FIT AND TIGHTEN THE NEW BLADE. THERE IS ALSO POSSIBILITY TO TIGHTEN THE
BLADE BY TORQUE METER.
- ALWAYS PAY ATTENTION TO THE TEETH OF THE BLADE’S DIRECTION IS CORRECT. IF NOT CORRECT IT.
CUTTING SPEEDS
THE MACHINE HAS TWO PRE-SELECTED CUTTING SPEEDS OF 34 AND 68 m/sec. CUTTING SPEEDS HAS TO BE SELECTED
ACCORDING TO THE GRADE AND DIMENSIONS OF THE MATERIAL. IF ANY VIBRATION AND/OR NOISE RISES FROM THE BLADE,
CHANGE THE SPEED.

Tooth Style Selection
Economies of cutting can be achived by chosing the tooth
style or shape correctyle suiled to the being cut.Saving can
be made by selectong the best tooth style because of:Faster
sawing,more accurale sawing,longer blade life abd less
breakage of teeth,
The following four (4) tooth styles are avaible.
Standart Tooth (N)
0° rake angle,fully rounded gulet,general purpose
Skip Tooth (L)
0° rake angle,low tooth height,flat gulet-to be used for bitle
materials of larger diameters,i.e.
bronce,brass,zinc,aluminium gales & risers,plastics.
Hook Tooth (KL)
10° positive rake angle with wide spacing between
tips,deep gulles-suitable for NF-metals,low carbon
steeli,large diameters.
Combi Tooth and Positive
The tooth pitch varies thougth the blade,regular,tooth
patlern broken up the reduce noise,less vibration and
chatler,longer balde lifesuitable for a wide range of cutting,
İ.e. structurals,pipe,tubing and micellaneous steels.
Tooth Set Selection
The purpase of ‘sel’ in a bandsaw blade is to provide
clearance and to allow the body of the blade to pass freely
though the materiall being cut.The sel depends on stock
diameter,shape and material to be cut.
Regular or Raker-Set
Is the most widly used setting.If consits of a repetitiv
patlern with one tooth set the right,the next to the left and
the third(the raker)wilhout set.This type of set is best
where the material being cut is uniform size;also used in
contour sawing.
Right-Left Set
For sofler materials, i.e. NF-metals,plastic&wood.
Group Set
For vibration free sawing of smaller diameters such as pipe
tubing and shapes-faster cutting speeds and smoother
sufaces.
Wavy Set
Spaceial set for cutting thin stock or variely of shapes and
thicknesses without changing the blade.
Combi Tooth Set
With 0° rake angle.Consisles pf teeth set allernately right
and left regular intervals with a raker tooth-excellen for
cuttin a variely of shapes and pipes 15mm wall thivkness
and upwards.
