1.1. Machine determination The band saw Proline 420.350 Asx is determined for cutting and shortening of rolled bars and drawn bars and profiles from steels, stainless steels, non-ferrous metals and plastics with no angle cutting.
Wear protective shoes with non-skid soles! The unsuitable shoes may cause balance loss and following injury. Falling work pieces may cause serious injuries too. Wear protective goggles! Chips and cooling liquid may damage your eyes. Always wear ear protections! Most of the machines emit up to 80 dB and may damage your hearing.
Do not remove or do not lock the limit switches or safety equipments! Any use of the saw, accessories or machine parts other than that intended by the BOMAR, spol. s r.o. company is not permitted. The guarantee on this product will be afterward lost and BOMAR, spol.
TOTAL STOP button is used for emergency switching – off the machine in case defect or health hazard. By pressing TOTAL STOP button is interrupted the supply of the electrical power. If any damages or fault appears, immediately press TOTAL STOP button! Release the pressing button is possible by twisting of the upper part of the button.
The doors of the protective fencing are protected by limit switches. If the limit switch is open, the machine is turned off. 1.6.5. Band saw cover It covers the visible area of the saw band from left guiding cube to the frame. Never switch on the saw band driver if this cover is not mounted! 1.6.6.

Level of acoustic pressure: Equivalent level of acoustic pressure A (noise) at operator position are L =76,3 dB. Mentioned values are Aeqv levels of emission which doesn’t have to represent safe levels. Factors which influence real level of acoustic pressure on machine operator are: working place characteristics, cut material, saw band. These factors have significantly influence on acoustic pressure.
2.4. Transportation and stocking 2.4.1. Conditions for transportation and stocking Keep recommendations for the manufacturers for transportation and stocking!

The important factor for selection of the tooth system is length of the cutting canal with respect to the size of the product BOMAR recommended Variable tooth system for band saw. Attention! When you connect the machine to the electrical network...
Constant tooth system – the saw band has parallel tooth pitch all over length. This way is suitable for cutting of solid material. 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.
2.10.4. Tables for teeth selection SHAPED MATERIAL (D , S = mm) Note: Table shows tooth system selection for cutting one piece of the profile. For cutting of more pieces of the profiles (bundle), you must think of the size of the wall as double size of the wall of one profile (that means, size „S“ equates to 2×S). In table, there are tooth systems constant and variable.
3.1. Starting the band saw • » Switch on the main switch of the band saw. The main switch is placed on the switchboard side. • Refer the machine 3.2. Machine referring Before using the saw, you must refer machine. Referring is necessary for correct positioning of the saw feeders.

The guide cubes are equipped with valves, which must be open during operation The band saw Proline 420.350 Asx is equipped with cutting pressure regulation on the one guiding cube Pressure adjusting is performed with regulating screw on guiding cube.
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...
Page 48
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! Manual version: 1.00 / June 2011 Manual rev.:...
3.9.3. Bundle material cutting Attention: Manualbundle clamping device is not standard equipment. Without this device is a not possible cut bundle. Attention! If machine has bundle device then material maximal height is half. If you want to cut the material in the bundle, there are suggestions for the positioning of bundles Round material bundle: Take care especially with round material that the bars are put according to the picture.
4.1. Saw band dismantling During the dismantling, take care that you do not damage the limit switch if the saw band stretching. Lift the saw frame to the top position. Stop the saw frame in top position by control valve. Dismantle yellow protective cover of the saw band.
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. Put the saw band on both guide wheels. Make sure that the saw band ridge fits tightly to the wheel rim.
• The saw band falls from the wheels – The saw band and protective cover can be damaged. • The saw band runs on the wheel rim – The saw band and wheel rim can be damaged Start and stop saw band drive. Stop the main switch! Open rear cover of the saw frame.
Set the limit switch of the saw frame lower position. 4.6. Limit switch of the saw frame lower position adjustment If the lower stop of the saw frame was set, the limit switch must be set again. 4.6.1. Check setting Lower the saw frame to the bottom position.
In gearboxes, oil is used for the whole lifetime of the gearbox. We recommend replacing of the filling oil in case of repair. Attention: When replacing, use oils recommended by BOMAR or oils, which has comparable parameters from the other manufacturers. Do not forget, that mineral and synthetic oils must not be mixed! Use oils with specification DIN 51517 in the gearboxes.
If the hydraulic system is equipped with filter (2SF 56/48-0,063), replace the filter too. Note: When replacing, use oils recommended by BOMAR or oils, which has comparable parameters from the other manufacturers. Do not forget, that mineral and synthetic oils may not be mixed! Use oils with specification DIN 51524-HLP, ISO 6743-4 and viscosity grade ISO VG 46 in hydraulic aggregates.
• During time of duty the oil temperature shouldn´t exceed 60-70°C • check function of signaling components (thermometer, level gauge, dirty filter indicator) • Check the adjustment of working pressure To realize a high reliability of the power pack, the manufacturer lays down following inspection intervals three Interval...
