2. DESCRIPTION
Roller Adjustment Bushing
Roller Casing
Ring Blade
The two bushings, located in the left side of the main
saw housing,
are threaded to allow adjustment of
roller clearance.
The roller casing is a steel sleeve installed with an
interference fit into the saw housing. The sleeve has
a cam slot which provides the linear travel for the
engagement rollers. When the lever is rotated 90
degrees in this slot, it locks in place.
A choice of blades is available depending on what
material is to be cut. Blades are designed to cut
asphalt, poured concrete, block, brick, rebar, stone,
and other masonry
material. Wet cutting blades
demand a very good water supply. Since the blade is
driven by an inner “V”
edge that rides in a “V”
groove in the drive disc and since that “V” edge
wears and narrows, total retipping of the blade is not
allowed (see
also
“Retipping, Section 5). The
narrowing of the blade does not allow a retipped
blade to be driven.

Sufficient water flow is necessary for proper operation.
Water cools the blade; transports the cut material out
of the kerf (cut); and flushes abrasive material away
from the drive disc and engagement rollers.
