If necessary Check functioning of bench lever
9.3 DESCRIPTION OF ROUTINE MAINTENANCE
A. Adjustment of the blade guide bearings
Loosen the screws 110, rotate the cams 28, so that the blade guide bushings vertically position the
blade in axis (DRAW.6 ENCL.5). Tighten the dowels 113 slightly until the blade secured. Loosen
the dowels113 slightly (about 1/10 of a turn). The front blade guides must be positioned the
nearest possible to the piece to be cut. Check every 3 months the existing tolerance between the
blade guides, making sure that it does not exceed the blade thickness of one tenth of a millimeter,
so as to avoid inexactnesses in the cut squaring. Periodically check with mounted blade that the
blade guide bearings rotate freely.
B. Lubrication of mobile parts of piece locking vice
Remove jaw 32 (draw. 4 ENCL.4), withdraw vice 5 completely by lowering the lever 93. Clean
and grease the mobile parts of the counter-vice 4 and vice 5. Lubricate the band guide devices
regularly.
C. Cleaning of the coolant tank
The coolant tank can be cleaned by simply removing the crucible 13 which supports the
motor-pump (DRAW.8 ENCL.6). Empty the coolant from the tank and collect the coolant in a
container for future disposal. Clean away the shavings and the metallic powder, taking care not to
scatter this over the machine especially around the motor and the box containing the electrical
equipment. Fill the tank with the amount and liquid stated earlier.
D. Checking of bench lever functioning
Check regularly that the rotation release-locking lever is working properly. In the event of the
lever not locking correctly, loosen grub screw 81(draw.3 Encl.4), tighten nut 79 and fasten grub
screw 81 again. Make sure that with the bench lever in position 1, arm 3 which supports the bow,
can rotate freely.
10. INFORMATION REGARDING ENVIRONMENTAL NOISE
An environmental noise test carried out on the band saw machine, identical to the machine to
which these operation instructions refer, has given the following results:
ACOUSTIC RADIATION PRESSURE
1. L
Aeq
=71.9 dB (A)
2. L
Aeq
=87.2 dB (the maximum acceptable value is 140dB).
3. The level of background noise has no influence = 48.5-54.2 dB (A).
