2. Install the Tenzomat on the saw band and secure it with screws.
3. Stretch the saw band until it is stretched to the recommended value.
4.3.2. Saw band inspection
Check the saw band in the guiding cubes and on the wheels
4. Check, if the saw band is right in the guiding cubes..
5. Switch on the saw band drive and then after 10 seconds switch off saw band drive.
If the saw band drive is not possible to switch on, set the limit switch of the saw
band stretching.
6. Switch off the main switch.
7. Open cover(s) of the wheels and check position of the saw band on the both
wheels..
•
If the distance between backside of the saw band and the offset wheel is 1 mm ,
setting is right..
•
If the distance is bigger than 1 mm , or the saw band is on the offset of the wheel,
set the saw band.

4.4. Cooling agents and chips disposal
The quality of the cooling agent
will deteriorate due to:
If the solution is too weak: If the solution is too strong:
•
use of contaminated water
•
impurity
•
outside oil contamination
(hydraulics, gears)
•
high operating temperatures
•
lack of air circulation
•
wrong concentration
•
corrosion protection is
diminished
•
lubrication decreases
•
microbial attack is more likely
•
the cooling ability is decreased
•
foam behaviour increases
•
emulsions stability deteriorates
•
sticky residue develops
4.4.1. Coolant device inspection
The state of the cooling agent has significant influence on the cutting quality and on
the operational life of the machine. Lifetime of the cooling liquid is 1 year, after this time
we recommend change the cooling liquid. This time is dependent on the degree of
pollution cooling liquid (especially with oils) and on the other factors.
Check level of the cooling liquid and function of the pump periodically!
Note:
If the state of the cooling liquid is not satisfactory, the cooling
liquid must be changed.
