The clamping action is such that both the front and rear of the guide are
clamped to the table, ensuring that the guide fence is held rigidly during
the cutting operation.
weathering, machining, drilling and boring etc set up varying
stresses in the table which, if given the opportunity, (like with a long
slot cut across more than half its width) will cause the table to 'move'. To
counteract this possibility a small housing is machined at the front of
the slot into which the stabilising bolt is fitted and clamped with the
butterfly nut. This ensures that the two most vulnerable parts of the
casting are clamped together in a single plane, to prevent warping and
twisting (Unseen).
The mitre fence slide can be engaged in the slot in the saw table,
and acts as an X-feed device, which will enable any angle from right
to 45 degrees left or right to be cut with the saw (See Fig 6).
connected to a threaded rod that is engaged in a threaded hole in the
mounting bracket 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.
tracking has been established (See Fig 2).
The lower saw wheel and integral pulley wheel is likewise mounted on
double bearings, onto an axle that is housed in an adjusting 'box trap'
mounting. This box trap is used to set the Lower Saw Wheel to DATUM.
It is the base parameter that the rest of the saw is set against. It is highly
recommended that, except in the most dire of circumstances, you DO
NOT ALTER the factory setting.
The drive belt is tensioned by turning the motor against a fixed point,
pulling the belt tight and then locking the motor in position with its
clamping bolt. During the turning operation the clamping bolt moves
within the slot that is machined into the motor mounting flange plate.
An 80mm diameter dust extraction outlet (See Fig 2 Backview).
The On/Off buttons, controlling an NVR switch. The green 'I' is the 'on'
button, the red 'O' is the off button (See Fig 1 Front view).
