- Assemble the new blade.
- Tension the blade by turning the gear to position "A" (Picture 7.6.1).
- Check the position of the blade on the two pulleys:
the blade must lay on the two pulleys, except for the sharpened segment, which
must stick out from the pulleys (Picture 7.6.3).
Turn the two pulleys manually and check that the blade is properly positioned.
- Close the housing "1" and lock it in place with closure "3"
- Connect the electrical plug back into its socket.
- Turn the differential circuit breaker back to "1".
- Start and stop the machine and check whether the blade
stays in its proper position compared to the pulleys.
7.6.3 Type of blades
There are several types of blades available on the market
that differ in terms of tooth spacing, blade thickness,
height and type of steel.
We recommend that you use blades in tempered
steel, 16 mm high and with teeth spaced apart by 7
mm on our bone saws.
For special applications, such as poultry or frozen
meat, there are specific blades with different tooth spacing that offer a perfect cut
without chips and without
altering the product.
