Machine disposal after lifetime Pour all service fluids (cooling liquid, hydraulic oil) from the machine over into designated reservoirs.
2.8.1. Filling the hydraulic unit with oil Fill the tank with one of the oils stated in the chart below. These are hydraulic oils class HM and HV in accordance with the European CETOP RP 91H specification in viscosity classes ISO VG 32. Do not pour the oil directly from the barrel into the tank but use a filtration device with a grid spacing of 20 µm or finer.
2.10. Electrical connection Attention! Only a qualified professional must carry out the servicing and repairs of the electric equipment! Take special care during work with the electrical equipment. High voltage accident can have fatal consequences! Always follow instructions for work safety. Electrical parameters of the machine: Service voltage: ~ 3×400 V, 50 Hz, TN-C-S...
2.10.2. Check of connection to the electrical network Attention! When you connect the machine to the electrical network secure a correct connection of all phases! THE HYDRAULIC AGGREGATE ENGINE MUST NOT BE OPERATED IN REVERSED DIRECTION FOR MORE THEN 10 SECONDS!!! 2.11.
BOMAR recommends variable tooth system for its band saws. In the table below the type of the tooth system depending on the sizes and profile of the cutting material is advised.
2.13.4. Tables for teeth selection: SHAPED MATERIAL (D , S = mm) Note: Table shows tooth system selection for cutting one piece of selected profile. When cutting more pieces of the selected profile (bundle), you must double the corresponding wall thickness of the profile to get an accurate estimation (i.e., wall thickness equates to 2×S).
3.1. Starting the band saw » Turn the main switch into position 1 – ON. Main switch is placed on the control panel at the front. 3.1.1. Throttle valve The valve regulates the movement of saw band into cut. Throttle valve is located on the left side at the front above the control panel (see arrow).
TOTAL STOP button In a case of emergency, this button immediately stops the machine. Main switch Switches the saw on /off Saw band speed and rinsing switch Tap symbol – only rinse the saw band while it holds still. Position 1 – saw band speed 32 m.min with cooling.
3.3. Machine control 3.3.1. Semi-automatic cycle Cutting: Move the saw frame into the initial position (further from vice) by button “5“. Set the cutting angle (see chapter Angular cut setting). If you want to make a vertical cut (i.e. 0°), screw the auxiliary metal boards to the fixed vice jaws (see below).
Press button “4“ (Start) to start the cut. Attention! You can stop the semi-automatic mode by pressing button no. 5 or the TOTAL STOP – emergency button. Attention! Saw frame movement can be stopped only by closing the throttle valve or pressing the TOTAL STOP button! 10.

Open corresponding cover on the side of the saw. Move the saw frame to the back position (furthermost from vice). Pull out the locking pin (arrows). Grip the rubber handle (arrow 1) on the saw frame and loosen the locking lever (arrow 2).
Put the locking pin back into the opening. If you are setting the angle with the help of the stops, make sure the head of the bolt of the angular stop rests either against the locking pin or against the facet on the other side of the frame (see below).
If you are cutting long pieces (for example rods, tubes), you must use a roller conveyor for shifting the material to the band saw. Contact Bomar for more information about roller conveyors. Make sure the conveyor is long enough and the material cannot drop off the conveyor.
4.1. Saw band dismantling Open the cover on the pedestal (side of the driving wheel). Open upper cover of the tightening wheel and lower cover of the driving wheel (after loosening the securing screws with plastic head). Dismantle the yellow protective cover and guiding cubes. The cover is fastened by two hex screws.
4.2. Saw band installation Prior to installation, clean the track wheels, guiding 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. Insert the new saw band in the guide cubes. Make sure the saw band runs between both guiding rollers and that it is pushed all the way to the top.
4.3. Saw band stretching and inspection Correct saw band stretching is one of the most important factors, which influence accuracy and saw band lifespan. Stretch the saw bands according to the band saw and the selected saw band type. Keep to the recommendation of your manufacturer.
Open cover of the wheels and check the position of the saw band on the both wheels. • If the distance between backside of the saw band and the wheel rim is 1 mm, the setting is right. • If the distance is bigger than 1 mm, or the saw band runs on the rim of the wheel, adjust the saw band.
4.4.2. Adjusting the limit switch of the saw band stretching After the saw band is replaced, the limit switch setting must be checked. If the limit switch is not set correctly, the band is stretched either too much or too little.
Release the stop screw and at the same time grip the saw band by hand and check if the hard metal guide does not put up to much resistance against the movement of the band. As soon as it is possible to move the band without resistance the hard metal guides are adjusted properly.
Set the brush to the saw band. Ends of the brush bristles should not touch the base of the saw band teeth (see picture below). Attention! The brush must not touch the bottom of the saw teeth! Tighten the bolt again and switch on the saw band drive. If the brush is adjusted properly, it runs fluently together with the saw band.
4.4.7. Saw frame furthermost position stop adjustment This stop limits the furthermost position of the saw frame from the vice. This stop has to be checked at least once a month. If the lower stop is adjusted incorrectly Move the saw frame to the furthermost position Release the nuts of the adjusting screw and adjust the stop Fasten the adjusting screw with the nuts again Set the limit switch of the furthermost arm position...
Switch setting Release the nut of the stop screw and screw in the stop screw Move the arm to the furthermost position stop and turn on the band drive Screw out the stop screw until the band drive stops Secure the screw with nut again and check the limit switch setting once more 4.5.
Use oils with DIN 51517 specification for the gearboxes. Select the ISO VG viscosity class according to the original oil. Attention: When replacing the oil, use oils recommended by BOMAR or oils from other manufacturers, which have comparable parameters. Do not forget, that mineral and synthetic oils must not be mixed!
Use oils with specification DIN 51524-HLP, ISO 6743-4 and viscosity class ISO VG 32 in hydraulic aggregates. Note: When replacing, use oils recommended by BOMAR or oils, from the other manufacturers which have comparable parameters. Do not forget, that mineral and synthetic oils must not be mixed!

4.8. Worn parts replacement 4.8.1. Hard metal guides replacement If the hard metal guides cannot be adjusted any more, they have to be replaced. Remove the hosepipe leading to the cooling agent tank and dismantle the saw band and saw band guiding cube. Fasten the guiding cube in a vice and screw out the screws on both hard metal plates.
4.8.2. Saw band guiding rollers replacement If the saw band is not sufficiently guided by guiding rollers and/or if the rollers are obviously worn, the rollers should be replaced. Attention! Guiding rollers must be replaced on both guiding cubes! Remove the hosepipe leading to the cooling agent tank and dismantle the saw band and saw band guiding cube.
Put new guide rollers on the eccentrics and screw the eccentrics to the guide cube. Now insert a short test piece of a saw band (cca 15 -- 20 cm) into the guiding cube. Adjust both eccentrics so that the band runs in the middle of the milled groove.
5.1. Mechanical problems Problem Possible causes Repair Wrongly adjusted hard metal Set according to the chapter „Servicing guides. and adjustment“ Worn hard metal guides. Replace according to the chapter „Worn pieces replacement“ Wrongly adjusted cubes of the Set according to the chapter „Servicing saw band guiding.
