General
Safety Notes
All installation work including t e electrical connection must only be carried out by qualified
personnel.
T e mac ine must only be operated by a tec nically trained and experienced operative w o is
also instructed in ‘safety at work ’ procedures.
Any adjustments, cleaning, repairs or c anging of t e saw blade must under no circumstances be
performed unless t e mac ine is fully isolated from t e electrical power supply. Ensure t e
emergency stop button on t e control binnacle is pressed and t e power supplies at t e mains are
disconnected.”
T e band saw must be regularly inspected and maintained in good serviceable condition. Eye
protection, ear protection, gloves and protective clot ing must be worn w en any of t e above
procedures are being carried out, as well as w en cutting fluid is prepared, introduced or displaced
from t e band saw mac ine (t e relevant environmental regulations must be observed in case of
t e use and disposal of cutting fluid etc.)
T e band saw must be installed on ground. Observe t e permissible floor load. T an t e band
saw mac ine as been properly bolt to ground securely.
Allow sufficient working space around t e band saw of at least 1 meter. İnstallations of stock roller
conveyors require additional space and possibly a lifting mec anism for eavy work pieces.
Always ensure t at t e working area around t e band saw is well lit.

Safety
İ
nstructions
Be sure t at electrical connection is made carefully. To avoid unwanted situations like electrical s ock, protect t e main supply cable wit a olster.
Before running t e mac ine, be sure t at all of t e protections are mounted properly and all t e covers are closed.
Avoid from smoke and moisture.
Please use t e parts and equipments w ic are recommended. Usage of unsuitable parts and materials w ic are bigger t an t e capacity of t e mac ine can cause unwanted situations.
C eck t e mac ine and inform t e defects everyday.
Don’t leave any material after c ancing t e band.
Do not old t e material w ile t e mac ine is cutting. Always tig ten t e material by using essential parts.
Please pay attention to c oose t e area of t e mac ine w ic doesn’t include anyt ing t at creates difficulties to control t e mac ine
Please be sure t at t e teet of t e band are looking to correct direction.
•Don’t leave t e band on t e ground or any place t at is dangerous for ot er people.
•Be careful w en using t e mac ine and keep t e working area clean ( clean t e saw dusts and oil traces )
•Pay attention to security instructions w en using t e mac ine.
•Don’t wear loose clot s w en using t e mac ine.
•Regardless use t e protective gloves w en using t e mac ine.
•Don’t get close too muc to t e mac ine w en running.
•Before carrying out any cleaning or maintenance procedure, disconnect t e mac ine from main supply.
•İn some conditions, noise level can be about 80 db. Band c oice 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 t e mac ine if you notice any fault of t e mac ine or absence of any part of t e mac ine.
- Control t e emergency button at least once a week and be sure t at it is working properly.

supply in t e electrical panel. R, s and t shows the phases, n is neuter and pe is
grounding. Connection will be from t e 13(l1) klemens w ic is at rig t klemens group.
C eck t e voltage w ic is mentioned at t e first page of t e manuel before setting t e
electrical connection of t e mac ine.
İf t e cable p ase line is correct p ase control led lig tens in t at way it is prevented to
motors move on wrong ways. Be sure t at t e out-put voltage at t e power supply is 22 ~ 28
vdc.
T e mac ine is protected against s ort circuit wit interrupters and against ig voltage wit

Limit Switches
Upper limit switch: after cutting, t e bow is raised by ydraulic cylinder up to t e adjusted level on t e spindle. It can be adjusted by
sliding t e limit up or down.
Lower limit switch: after cutting t e material, t is switc provides t e control valve switc ed off and rises t e bow up.
P.s. Its place is adjusted by manufacturer, do not c ange if unnecessary.
Blade breaks out limit switch: w en t e blade as broken or not tig tened, it prevents t e drive motor working.
Pulley cover open limit switch (optional): t is limit switc stops t e mac ine w en t e protection cover at t e back of t e bow is
opened.
- The Adjustment Of Cutting Pressure
According to t e grade of material, it provides to regulate cutting pressure. T e cutting pressure s ould be reduced w en t e blade is
being dull. After t at t e blade must be c anged.
- Adjustment Of Upper Limit Switch Before Cutting
Bring down t e bow till it approac es to t e material about 5mm.
For preventing t e bow go up more t an necessary;
Loose t e part w ic presses to t e switc ,
Turn it towards t e switc and tig ten it w en it touc es t e switc .
The indicator of manometer must be in the green area (area ii). If the indicator is in one of the red area, this means that the
tension of the blade is not in the acceptable level and it may cause unwanted results.
