ADJUSTING THE BLADE
To ensure that the machine is running properly, one must check that the band is running true on the pulleys. To
be correct, the band has to rest with the rim of the blade aligned with the front end of the pulley. See Figure 5.
If it is not aligned, proceed to correct the alignment, by adjusting the inclination assembly knob (M) as follows.
Unscrew the cap (S) to accede to the knob (M). Loosen the nut by means of lever (N) to free the inclination knob
(M). You will observe that by screwing the knob when at the same time turning the band by hand, the blade will
move backwards. Similarly, when we unscrew it, the blade moves forward. The centring operation must be carried
out by screwing and unscrewing the knob so that the deviation of the band is minimal and does not drop off (M).
Remember to turn the pulley by hand each time you adjust the inclination knob (M).
After replacing a band, you must ensure the blade is running true, before you run the machine.
CLEANING
To proceed with cleaning the band saw, disconnect the plug from the mains. Open the door (B), loosen the
tensioner (H) and remove the band. Unscrew the scraper securing knob, remove the scrapers (O) and the upper
pulley pulling it up. For BM-3000JV to disassemble to the upper pulley ( I ), unscrew the cover (T), that access to
the rear part of the axis, with allen key 8, unscrew it in clockwise. Disassemble the scrapers (E) throwing of the
retention rings and retire the scrapers wheels (X) throwing of them while it presses its spring.
To clean scrapeprs and wheels, use a stiff brush and hot water.
With a damp cloth, hot water and a neutral detergent, clean the inside of the door and body, as well as the
exterior, together with the blade and guards, etc. Finally, dry it off with a cloth.
In BM-3000JV, to empty and clean waste product tray move it backwards and pull it up from its inferior part to its
horizontal position dropping the waste, cleaning it with a damp cloth, hot water and a neutral detergent and finally,
dry it off with a cloth.
Pay special attention to residues that can accumulate on the corners, pulleys, pulley grooves, lower scrapers and
the back bearing covers.
To remove the lower pulley you must extract bolt (P). To loosen, unscrew clockwise as these are left handed
threads, pay attention to o-rings placed between pulley (J) and bolt (P)
Avoid dripping water onto the electrical zone.
MAINTENANCE
After 200 hours of work, it is advisable to grease with edible grease the guides (Q) of the tensioner, removing the
cap (S) and the rear top cover (T). Likewise, remove the tensioner; grease the spring (V) and the thread of the
tensioner. We recommend changing the bearing (R) after 10.000 hours of use.
SOUND LEVEL
According to the noise’s test, we declare herewith that the noise level with no load is
74
dB (A), and under load
is 7
9
dB(A).
The uncertainty KPA and KWA values are 3 dB for both operating conditions.
Any non-ionising radiation is expected from the machine.
