Valve & Motor
The spring-loaded engagement rollers located in the
main frame of the saw on the left side of the saw
housing, force the blade against the drive disc to
assure constant blade rotation.
These rollers must
always be free to move in and out, allowing the
springs to force the blade against the drive disc as
the blade and disc wear.
The support rollers, mounted in the cover, hold the
blade against the engagement rollers.
The support roller cover, which contains the two
support rollers, is the top portion of the saw that is
removed when installing the blade.
The drive disc alone drives the ring blade. The inner
edge of the blade rides in a “v” groove in the drive
disc and forms a metal to metal contact. This drive
mechanism is mounted directly to the motor shaft and
rotates at 14,000 RPM.
The valve and the motor share the same housing.
The valve is a mechanical device that controls
direction and amount of oil flow. The motor converts
oil flow to rotational motion.
