HEAD DOWN LIMIT SWITCH
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 in the Manual
mode. 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 made with the Head fully down and when the spring
post contacts the limit switch at the top of its travel. The Head Down Limit switch is
located on the head frame near the pivot point as shown in the photo.
Adjustment of the limit switch is made by changing the position of the set bolt, which
is located on 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.

need lubrication on a regular schedule. The lubrication requirements are primarily the saw pivot points which are equipped
