Tensioning the blade
Before tensioning the blade, check the air pressure gauge to see that the air tension system is properly
charged. The gauge should read 44 PSI, i.e. 0.3 MPa (yellow colour) with the blade tension completely
released. To add air pressure attach an air pump to the air valve. To release air, push in the valve stem.
See Figure 2-6.
To tension the blade use the tension handle, when the ball valve handle is in “1” working position. To
release, shift the ball valve handle in “0” loosing position. The blade tension handle should be placed in the
handle grip when not use.
The tension gauge should be checked occasionally when adjusting the cant control or while cutting. Ambi-
ent temperature changes will cause tension to change. Adjust the tension handle as necessary to maintain
