7.6 - Saw frame lowering control device
It is an optional accessory, ideal for the cutting of thin or STAIN-
LESS STEEL section bars, that determines a constant lowering
and consequently a good efficiency of the blade throughout the
work phase. This device can be accommodated to the different
situations and applications. Defectiveness in the control of the
lowering may be caused by the drop in braking power of the
device due to the long-term blow-by of the braking fluid.
Push rod (2) back into its seat and loosen plug (3). Use recom-
mended oil to top up oil tank (4) with the help of a syringe-type
pump. Bleed air, after having tightened plug ( 3 ) and loosen
screw (5) lightly until a little oil drip out; when this has been
completed, secure the screw.
Use SHELL HYDRAULIC OIL 32 or similar.

7.4 - Spring adjustment
The sawframe balance can be adjusted through the handle
( A ):
- Put the spring under tension when you operate the machine
manually so that the sawframe can easily raise up to the start
position.
- Reduce the spring tension before you switch to the self -
downfeed function so that the sawframe can descend according
to the downfeed speed adjusted on the regulator ( 5 ).
7.3 - Vice
- The device does not require any particular adjustment; in case
of excess play of the sliding guide, tighten slide screw
more.Place the piece to be cut inside the vice by moving jaw
to about 3 - 4 mm and lock with lever.
- Mount the new blade and put it under tension through the
relevant handwheel.
- First, adjust the mobile pad (use the spanner n.2) so that you
allow 0.05mm distance between pad and blade. Once you get
that distance, you can fix the screw (use spanner n.1) and the
nut (use spanner n.3).
- Use now the spanner n.4 so that you allow 0.2mm distance
between the fixed pad and top of the blade. Once you get that
distance, you can fix the screws (use spanner n.4) making
sure that the blade-guide block is perpendicular to the blade.
- Use the spanners n.7=11mm and n.6=3mm to release the
screws as shown here. Use now a screwdriver to rest the
bearing against the blade allowing a light pressure so that the
blade is driven to enter straight into the pads. After that is
done, you can fix both screws and nuts.
The above adjustment is very important to get straight cuts and
longer blade life.
Also, we recommend to clean and lubricate the parts making
sure that coolant liquid flows abundantly.
7.5 - Cutting angle adjustment
- Unlock lever (8) and rotate the saw frame arm until you reach
mechanical stop and check if the index corresponds to 45°; if
not operate on the set screws to make measures meet.
