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. İnstallations 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 İnstructions

ØBe sure that electrical connection is made carefully. To avoid unwanted situations like electrical shock, protect the main supply cable with a holster.

ØBefore running the machine, be sure that all of the protections are mounted properly and all the covers are closed.

ØAvoid from smoke and moisture.

ØPlease 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.

ØCheck the machine and inform the defects everyday.

ØDon’t leave any material after chancing the band.

ØDo not hold the material while the machine is cutting. Always tighten the material by using essential parts.

ØPlease pay attention to choose the area of the machine which doesn’t include anything that creates difficulties to control the machine

ØPlease 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.

·İn some conditions, noise level can be about 85 db. Band choice and cutting speed is important factor for noise level.

·İllumination 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.

of the machine as stated in the chapter on the operation of the machine and the adequate

preparation of the operators as regards the specific risks linked to the operation of the machine.

İf the machine isn’t used according to instruction given in the ‘purpose of the machine’ chapter in

this manual, the manufacturer isn’t responsible for any damage caused to people and things.

Furthermore, the manufacturer isn’t responsible for any damage to people and things and things

resulting from the non-compliance with the following warnings.

A) Adopt all the necessary precautions during loading, calibration, part replacement,

cleaning, and repair or maintenance operations to prevent someone else from turning

the machine on.

B) Do not temper with the safety devices and guards on the machine.

C) Do not remove any of the safety devices and guards on the machine.

Always make sure that safety devices and guards are remounted after their temporary removal for

technical reasons ordered by the boss

Connection To The Electrical System

Control panel is mounted on the electric panel. Machine is connected to the main

supply in the electrical panel. R, s and t shows the phases , n is neuter and pe is

grounding. Connection will be from the 13(l1) klemens which is at right klemens group.

Check the voltage which is mentioned at the first p age of the manuel before setting the

electrical connection of the machine.

İf the cable phase line is correct phase control led lightens in that way it is prevented to

motors move on wrong ways. Be sure that the out-put voltage at the power supply is 22 ~ 28

vdc.

The machine is protected against short circuit with interrupters and against high voltage with

thermal relays. Grounding and neutralizing have to be done to protect the machine .

Changing The Hydraulic Oil

Pouring Out The Hydraulic Oil

üLower down until it receives the cutting head.

üRemove hydraulic hose union at head lifting

üPut the removed hydraulic end of the hose into a

container.

üEmpty the oil by pressing head lifting button at control

panel.

After empting the oil, fix the hydraulic hose union to the same

place.

Hydraulic oil:Iso 46

Tank capacity:30 lt

System capacity:36 lt.

Refilling the hydraulic oil

The hydraulic oil filling

üRemote the bolts of hydraulic drawer, then pull it out.

üOpen the store cover.

üPour 46 numbered iso hydraulic oil into tank. (8lt

capacity.)

üClose the tank cover and move the drawer into the

body

Fasten the screws to the body again with the help of hydraulic

drawer.

Filling Of Coolant

Consisting of a mixture of liquid and water coolant liquid should be used for steel cutting. Coolant should not be used for

cutting casting. Specific periods of time (at least once a month) , coolant should be drained and clean chips. İf amount of coolant is not

enough, add to the tank. (4 liters of tank capacity. Collant mixing ratio 1/10)

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. İf not correct it.

Cutting Speeds

The machine has two pre-selected cutting speeds of 20 and 100 m/sec. Cutting speeds has to be selected according to the grade

and dimensions of the material. İf any vibration and/or noise raises from the blade, change the speed.

·All the details about the cutting of various materials and dimensions are given below
