An integral function of the S-20 Series II is the ability to make mitred cuts at angles between 90
degrees and 45 degrees. The Head swing of the S-20 Series II is easily changed to set a different cutting
angle by first releasing the Angle Brake lever, and then manually moving the Head to the cutting angle
desired. An angle scale with a pointer in clear view of the saw operator allows for accurate setting of the
cutting angle. The Angle Brake lever is then locked in position by forcing it into the down position. It
should be noted that the angle brake should be locked into position whenever cutting with the saw. The
photo below illustrates the Angle Brake in the locked position at 65 degrees. To set the saw to the 90
degree position, the Head ( in the fully down position ) is moved until the frame meets the 90 degree stop
bolt which is located in the coolant tray at the drive end of the head.

The Head down limit switch operates to cut power to the blade motor and the coolant pump motor
when the Head has descended to the bottom of its travel. The Head is adjusted so that the blade will
descend slightly past the level of the vise wear strips. This setting is critical to ensure that the blade has
cut fully through the stock. The Head Down Limit switch is located in the electrical box and is mounted in
such a way that as the Head descends the counterbalance spring post contacts the limit switch roller.
Adjustment of the limit switch is made by changing the position of the set bolt which is located in
the end of the spring post. Lengthening the set bolt will cause the limit switch to activate sooner as the
spring post meets the limit switch roller. Shortening the setting bolt by turning it into the spring post will
lengthen the time before the Head limit switch is activated.
