The lower blade guide assembly is mounted on the main saw frame below the
table, it mounts the rear thrust bearing and two side guides that keep the blade
stable (straight and untwisted) below the table during the sawing operation.
The lower guard is two half red plastic enclosures that screws to the guide assembly,
and shields the blade between the underside of the table and the top of the lower
saw wheel compartment.
The fence guide rail is a metal extrusion that is bolted onto the saw table.
The fixing locations in the guide rail are slots, which allow the angle of incidence
between the table and the guide rail to be adjusted; to enable the guide fence
to be set square to the table. There is a ruler scale set in the guide rail to aid the
setting of the guide fence.
NOTE. The guide fence rail should always be fitted and securely fastened to
the saw table, even if it is not properly set up for the fence. This is to help
maintain the stability of the saw table in the area of the slot which is cut
through the table to allow the blades to be fitted.
The inner edge of the upper guide assembly is toothed to form a rack.
The pinion part of this mechanism is on the end of the shaft connected
to the blade guide adjusting knob. Turning the knob will allow the guide
assembly to be raised or lowered (provided the clamp is loosened).
An extruded aluminium assembly primarily consisting of the main mounting body
and the blade. The blade is bolted to the top of the main body. The main body is
shaped to fit over the fence rail and mounts the clamping handle. The clamping handle
is attached to a torsion bar which is fed through the blade of the guide and acts on the
rear clamp, pulling it tight against the back rail through the lever action of the clamp
handle. There is a fixed measurement scale mounted on the fence rail. On each side
of the main body is an aperture through which this scale can be read. Mounted in each
aperture is an adjustable index, to enable the measurements to be zeroed.
The mitre fence slide can be engaged in either of the slots in the saw table, and acts
as an X-feed device, which will enable any angle from 0 to 45 degrees left or right to
be cut with the saw.
An aluminium extrusion bolted to the rear of the saw table, that is used as the rear
clamp bracket for the guide fence.
The tracking control wheel, at the rear of the top compartment, is connected to a
threaded rod that is engaged in a threaded hole in the base plate of the upper saw
wheel axle assembly. The end of the rod pushes against the lower end of the hinged
tilting plate that carries the upper saw wheel axle. Driving the rod in or out will cause
the plate to tilt, and by association, the upper saw wheel, thus enabling the blade to
be 'tracked' . The tilting plate is kept in contact with the end of the threaded rod by
the tension on the saw blade, (the downward 'pull'). It should be self - evident therefore,
that the blade can only be 'tracked' whilst it is in tension.
