2.10.1. Machine working conditions
Keep the conditions of the manufacturer for machine operating! If recommendations
are not kept, damage can occur to the machine.
The manufacturer warrants the correct function of the machine for these
conditions:
• At temperature air from 5°C to 40°C, the temperature average during 24 hours
must not exceed over 35°C.
• At relative dampness of the air in the extend from 30% to 95% (not concentrate).
• Altitude lower than 1000 metres.
• Do not expose the machine to the radiation (for example microwave radiation,
ultra-violet radiation, laser radiation, x-ray radiation). Radiation can cause problems
with the machine function and deteriorating condition of the isolation.
2.10.2. Band saw unpacking and assembling
Remove the packing from the machine and unpack all parts.
2.11. Machine installing and levelling
Check the floor supporting capacity before machine installing. If the floor capacity does
not agree with requirements, you must prepare the necessary base for the machine.
Minimal requirement:
Machine weight – Practix 285.230 G
Manual 215 kg / Pulldown 225 kg
+ Weight of accessories
+ Maximum weight of material
• The machine must be levelled at the horizontal position. All feet of the machine
must touch with the floor after levelling.
• The machine must be levelled by means of the calibrated spirit level. Spirit level is
put on the vice area. Set the roller conveyors according to the spirit level.
• For machine levelling, take care that there is sufficient available space for
operation, repair work, servicing of the machine and handling the material.
• The machine including appended parts and accessories must be visible from the
place of operation.
2.12. Machine disposal after lifetime
Blown out all service fluids (cooling liquid, hydraulic oil) into designated reservoir.
Dismantle machine into separate parts and dispose them in accordance with valid
directives.
2.13. Electrical connection

Electrical parameters of the machine:
• Service voltage: ~ 3×400 V, 50 Hz, TN-C-S
• Total input / Max. fuse: 1,1 kW / 16 A
Before connecting switch off the main switch of the power supply circuit for the
machine and ensure dry place when doing connecting works!
Service voltage must agree with the line voltage!
Crosscut of the supply line must respond with rated current for max. machine load.
Connect the service cable of the machine on the clamps of the electric distribution.
In case the machine is connected with a direct connection, an extra main switch must
be added which can be locked in zero position.
2.13.1. Check the direction of the saw band
After the machine has been successfully connected, briefly switch on the machine and
put the driving engine of the band in the running position. The direction must be in
accordance with the arrow direction on the saw band cover. In case the direction of the
saw band does not match, two phases at the terminal strip must be switched.
2.14. Filling of the cooling system
Prepare the mixture of the water and the cooling liquid. Keep the concentration
specified by manufacturer.
Fill the mixture of the water and the cooling liquid to the tank of the cooling system.
Area of the tank for the cooling liquid is discovered from the chapter „Technical data“.
Filling the tank with the cooling liquid, take care that the liquid does not drip out of the
tank and the tank does not overflowed.
Note:
The values of the crosscut of the conductor and the rated
current are in the norms.
Note:
The socket with the fork can be used only at the machines with
the rated current less than 16 A and total input less than 3 kW
Attention! In this case the extra main switch becomes primary
and the main switch on the machine has only secondary
function.

Keep by manufacturer specified recommendation for adding the anticorrosive agents,
the antifreezes or other agents! For mixture of two different mixes can produce toxic
and aggressive mixes, which can threaten your health or damage cooling system of the
machine
2.15. Check machine function
Check, if the machine or some parts of the machine were not damaged during
transport.
Check, if covers are installed and functional. Check by means of the Tenzomat if the saw
band is correctly stretched. If it is necessary, you can stretch the saw band according to
chapter Selection and replacement of the saw band. Values of the saw band stretching are
on the Tenzomat. Switch on the main switch and check the motors and systems (saw
band drive, hydraulic pump, cooling pump, chips conveyor).
Open and close the main vice. Turn the saw frame of the band saw from one outer
position to other outer position. Raise the saw frame to the top position and drop the
saw frame to the lowest position.
Start the machine with the cooling pump and let it run without load until the cooling
system will be filled with cooling liquid. As soon as the cooling liquid starts to escape
from the nozzles of the cooling system, the cooling system is ready for the operation.
Carry one cycle of cutting without material. Check, if the machine runs with no
irregularities. If all machine functions are right, the machine is ready for operation..
2.16. Saw band
Refit the saw band cover only after you have installed and tightened the saw band.
2.16.1. Saw band size
2720×27×0,90 mm
2.16.2. Selection of the saw band tooth system
The manufacturers provide the saw bands with constant and variable tooth system. The
important factor for selection of the tooth system is length of the cutting canal with
respect to the size of the product.
1. Constant tooth system – the saw band has parallel tooth pitch all over length. This
way is suitable for cutting of solid material.
2. Variable tooth system – tooth pitch is variable. Variable tooth system is used for
profiled materials and bundle cutting. Variable tooth pitch lowers vibration of the
saw band, increases service life of the saw band and quality of the cutting area.
In tables, there are advised type of the tooth system depending on sizes and form of
the cutting material.
Footnotes:
Z
p
Z – teeth number on one inch
S – tooth with zero angle of the teeth
K – tooth with positive angle of the teeth
Examples of the tooth system marking:
32 S – number „32“ means 32 teeth on one inch (that means constant tooth system),
letter „S“ marks teeth with zero angle of the tooth.
4–6 K – number „4–6“ means 4 till 6 teeth on one inch
(that means variable tooth system); letter „K“ marks teeth with positive angle of the
teeth
BOMAR recommends use variable tooth systém.

2.16.3. Saw band running-in
To ensure a full service life of the saw bands, we strongly recommend that you carry out
the „RUN-IN“ process.
Running in: Cut the material with the frame lowering reduced to 50% only. When
vibrations occur increase or decrease the band speed.
When cutting small pieces run the band until approximately 300 cm2 of material has
been cut. When cutting large pieces run the band for 15 minutes approximately.
When the band has been run, increase the lowering-speed to normal speed. The
running in of the saw band avoids micro-breaks on the cutting edges of new saw band
ensuing from first excessive stress. This would decrease service life substantially. The
optimal running in of the saw band produces ideal rounded cutting edges and
therefore the conditions for an optimal service life.
Note:
Run regrinding bands too!

as close as possible to the material.
1. Release the lever of the left listel and move left part of the
guide apparatus so that the left guide cube edge is as close
to the cut material as possible.
2. Lower the frame to the lower position and check the
position of the guide cube towards vice loading area. The
guide cube must be a distance of at least 10 mm from the
vice loading area.
3. Tighten the lever of the gib and check the guide cube setting once more for
possible collision with binding table or vice jaw.

injury!
3.4.1. Handling agent selection
• Use the strong handling agents to lift and transfer the material!
• Handle with the material only with the lift truck or use the suspension strands and
the crane!
• Do not use the lift truck or crane in case that you do not have the license to handle
with it!
3.4.2. Insertion
Insert material to the vice and ensure that the material cannot move in the vice or fall
from the vice after the clamping. If you cut long pieces of the material (for example rod,
tube), you must use the roller conveyors for material shifting to the band saw. Contact
Bomar for more information about roller conveyors
Make sure the conveyor is long enough and the material cannot tip off the
conveyor.
Be especially careful with round materials that it always stays on two vertical
rollers and that it cannot fall off the conveyor!

4.1. Saw band dismantling
1. Unplug the machine from the power supply. It guarantees that the machine does
not accidentally start running.
2. Open the protective cover on the rear side of the saw frame. Release the saw band
tension using the handle so that the saw band can be taken out easily.
3. Remove the saw band from rotation wheels.
4. Slide out the saw band from the guides.
4.2. Saw band installation
1. Prior to installation, clean all track wheels, guide cubes and inner side of the arm
thoroughly of all traces of chips and dirt. Keep in mind the teeth direction when
installing the saw band.
2. Insert new saw band in the guide cubes. Make sure the saw band runs between
both guide rollers and it is pushed all the way to the top.
3. Put the saw band on both guide wheels. Make sure that the saw band ridge fit
tightly to the wheel rim. Then push the saw band as far back as possible.
4. By turning the stretching star to the right, you will stretch the saw band slightly.
Now remove the plastic cover of the saw band teeth.
5. Close the rear protective cover.
6. Install the yellow protective cover of the band. The arrow on the cover must match
the direction of the arrow on the band. If it does not, turn the band round.
4.3. Saw band stretching and inspection
Right saw band stretching is one of the most important criteria’s, which influents
accuracy and saw band service life. Stretch the saw bands according to the selected
saw band and the band saw. Keep the recommendation of your manufacturer.
4.3.1. Saw band stretching
1. The saw band must not fall from the wheels after setting.

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.
8. Close cover of 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.

relevant regulations.
• Let the chips drip excess fluid!
• Fill a watertight container with the chips! Be careful that the container does not
leak, because even after a long dripping time, they still contain coolant residue.
• Place the container into the care of a disposal company equipped for the disposal of
chips contaminated with cooling liquid. In case the machine is equipped with micro-
spray installation, the chips must also be handed over to a disposal company.
4.5. Greases and oils
4.5.1. Gearbox oils
In gearboxes, oil is used for the whole lifetime of the gearbox. We recommend
replacing of the filling oil in case of repair.
