7.2 Adjusting the blade guide
- Disconnect the machine from the power source.
- Use a Hex. Wrench to loosen Hex. Socket screw (A) on
the square lock plate.
- Hold the handle (B) and slide blade guide block as close
as possible to the material without interfering with the cut
- Tighten the Hex. Socket screw (A).
- Reconnect the machine to power source.
Blade guide blocks
The blade is guided by means of adjustable pads set in
place during inspection as per the thickness of the blade
with minimum play as shown in the figure.
In case the blade needs to be replaced, make sure to always
install 0.9mm thick blades for which the blade guide pads
have been adjusted. In the case of toothed blades with
different thickness adjustment should be carried out as
follows:
- Loosen nut (C), screw (B) and loosen dowel (D) widening
the passage between the pads.
- Loosen the nuts (H) and the dowels (I) and rotate the pins
(E - G) to widen the passage between the bearings (F).
- To mont the new blade: place the pad (A) on the blade,
loosening the dowel, allow a play of 0.04 mm for the sliding
of the toothed blade, lock the relative nut and screw (B),
Rotate the pins (E - G) until the bearings rest against the
blade as indicated in the figure and then secure the dowels (I)
and nut (H).
- Make sure that between the blade and the upper teeth of
the pad (L) this is at least 0.2 - 0.3 mm of play; if necessary,
loosen the screws that fasten the blocks and adjust
accordingly.
BEFORE PERFORMING THE FOLLOWING OPERATIONS,
THE ELECTRIC POWER SUPPLY AND THE POWER
CABLE MUST BE COMPLETELY DISCONNECTED.
7.Changing the blade
To change the blade:
- Lift the saw arm.
- Loosen the blade with the hand wheel, remove the mobile
blade-guard cover, open the flywheel guards and remove the
old blade from the flywheels and the blade guide blocks.
- Assemble the new blade by placing it first between the pads
and then on the race of the flywheels, paying particular
attention to the cutting direction of the teeth.
