8.7 Changing the Blade

WARNING:
Before performing the following operations, the electric power
must be disconnected.
To change the blade:
- Lift the saw arm.
- Loosen the blade with the blade tension hand wheel,
remove the mobile blade-guide 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
(Fig 8-10).
Figure 8-10: Blade Cutting Direction
- Tension the blade and make sure it perfectly fits inside the
seat of the flywheels.
Figure 8-11: Wheel Guard Micro Switch
