3. Working places
Assembly and installation
After stopping of machine must be properly set up in the plane, fixed on stationary
pad and properly secured so as to avoid when working with the machine to its
inadvertent movement.
For safe operation with the machine must be around the machine safe space at least
a distance of 1 m from the machine.
During work with the machine small fragments can fall off from the cutting material,
so it is recommended to place the machine in the direction where there is no contact
with people and you can´t damage the surrounding objects.
After the placement on the working place you need to connect the machine to a
power source by using the cable with cable end.
It is recommended the power cable to cover in place of the movement of person and
handling of material, to avoid people tripping or falling objects on the power cord and
damage. Do not operate the machine with a damaged power cord or extension.
For safe operation, it is necessary to provide adequate lighting so that the operator
could see properly to all parts of the machine and the surrounding area.
Before starting the saw, it is necessary to check the proper tightening of the table and
blade tensioning.
The manufacturer recommends before work to start the machine and check all its
features.
For proper operation of the motor must be protected from overheating, after running it
is recommended to let it run so that it could be cool down during work. It is not
allowed more than 10 starts per hour.
The operator is required to keep the engine clean, especially the cooling fins and
cooling ventilator.
Clogged cooling fins reduce the cooling efficiency and increase wear out of the
electric motor. The engine could be shut down due to overheating.
Warning - ground wire (yellow-green) must be before operating the machine
connected properly.
During cutting heavy pieces of material must operate the machine more than one
person, the operator decides about the method of the cutting and then must lead the
cutting process.
!!Attention!!Operate the machine with a loose blade is forbidden!
Cutting
Band saw BAS-650 allows only perpendicular cuts (angle of 90 °).
Procedure for cutting:
- Before starting the saw is necessary to check the network connection, the
state of the power cord and connection cable covering (against damages),
condition and attachment of the cutting blade and condition and tighten of
the table and the fastening of the covers.

- After start of the machine by the main switch the motor starts and spin the
cutting band.
- Place the cut material on the cutting table, lean it on the cutting ruler and
move gradually towards the cutting zone, first test the cutting on a sample
- Cutted material must be moved fluently to get straight and fluent cut,
otherwise the band saw can be damage (the band can be twisted, it can
lead to its destruction).
- After reaching the end position of the cutting table, band saw turns off
automatically.
Band saw
Hard metal band saw is specifically designed for cutting of large-scale building
blocks. Cutting siliceous materials is prohibited - will damage the blade. It is
permissible to cut clay bricks or tiles.
Damage of the cutting blade is always caused by improper use.
4. Safety instructions
Installation of the blade
Before the replacement of the band saw, the operator must disconnect the machine
from the electrical system by disconnecting the power cord. Each part of the machine
should be cleaned from the remnants of the cut materials. If you are replacing band
saw after cutting, it is necessary to note with the fact that the band saw may be hot!
Open the top (Pos. 43) and bottom door (Pos. 44) of impellers, release tension lever
(Pos. 6) and lift the stop bar. After removing the cotter pins, remove the retaining bar
handles. Remove the band saw and remove all its potential remains. Insert the new
band in length with corresponding parameters and attach it in the reverse side. Pay
attention to the correct direction of teeth. After attaching the band must be properly
tensioned.
After tension of the band saw is recommended run machine for short time and check
the tension of the band saw and mounting.
