ADJUSTMENT OF THE LOWER BLADE GUIDE
The lower blade guide is composed by:
- a support plate which bears the saw blade from behind
(A)
Fig. 19 ,
- Two small hard metal bearings, which drive the saw blade sideways
(E)
Fig. 12.
These bearings must be adjusted every time you adjust or change the blade.
1.
Loosen the screw by hand (B)
Fig. 19
and move the knob in order that the bearing touches the back side of
the blade lightly.
2.
Loosen the two screws ( F )
Fig. 12
that block the pins of the side adjustment bearings; these bearings
should be placed, as the upper ones, 1 mm away from tooth’s basement. If this is not the case, you must
incline the workbench to 45° and open the lower door, loosen the bolt fixing the group and replace all the
elements in order that the bearings are 1 mm away from tooth’s base, then tighten the bolt, replace the
workbench and close the door.
3.
Bring the two bearings into contact ( F )
Fig. 12
with the saw blade.
4.
Turn again and again the flywheel clockwise by hand in order that the bearings are in the correct position: the
gap between bearings and blade must be less than 0,1mm as for the upper ones.
5.
Tighten the screw of the rolls firmly (F)
Fig. 12
.
6.
Replace the back bearing as in position 1.
DANGER!
Before performing any adjustment or maintenance task and before changing the blade you must
switch off the machine, disconnect it from the power supply and wait for the saw blade to stop.
