To Adjust the Crosscut Travel
(i)
With the mitre latch engaged in the 0° position.
slacken the mitre clamp.
(ii)
Loosen the lock nuts on each side of the arm. as
shown in Fig. 10.
(ill)
Release the mitre latch and depending on which way
the arm needs to move to give the true 90° crosscut
required, loosen and tighten the adjusting flanges on
either side of the arm (Fig. 11) if the front of the arm
needs to go to the left, loosen the adusting flange on
the right of the arm and tighten the flange on the left.
If the opposite is the case, and the arm needs to
move to the right, loosen the adjusting flange on the
left and tighten the flange on the right. Adjust the
flanges a little at a time and re-engage the mitre
latch and clamp and check the crosscut travel of the
blade relative to the fence with a square. Do not
overtighten the adjusting flanges or the mitre latch
will be too stiff to operate easily.
(iv)
Once satisfied that the crosscut travel is accurate,
retighten the lock nuts on each side of the arm (as in
Fig. 10).
(v)
Adjust the pointer on the mitre scale so that it
registers 0° in this position.

4.2. Checking the
Saw Blade is Parallel
to the Arm Tracks.
This check is to ensure that, in the straight 90° cross- cut
position, the blade runs true across the table and does not
run "dog fashion" (Fig. 12). If the blade is incorrectly
adjusted in this way. it will produce a cut wider than the
set of the blade (distance across the tips of the teeth). It
would also tend to cause scorch marks on the timber
being cut.
To Check
(i)
Place a square against the fence as in Fig. 9 and,
with the sawblade just in front of the fence in the 90°
crosscut position (lock it in that position with the rip
lock) check that the left hand face of the blade is
parallel to the square. If it is not parallel, adjustment
is necessary.
To Adjust
The illustration (Fig. 13) shows the components of the
yoke assembly. The precise alignment of rollerhead (8)
with yoke (17) is made possible by collar (I) which is fixed
to the yoke by the locking nuts (J).
(i)
Firstly, grasp yoke in both hands and check it for
movement left or right, if there is movement tighten
nut (H) which increases the friction between the rip
locating slide bar (K) and nylon block (L).
(ii)
Then, if the blade is still not parallel to the square.
release the yoke clamp (10) and loosen the lock nuts
(J) (Fig. 13/13a) and turn yoke slightly to left or right
until the blade is in fact parallel to the square and
therefore also parallel to the arm tracks. Then tighten
all nuts.
(iii)
Having adjusted the blade parallel to the arm tracks
in this way, release the rip lock and pull the saw
carriage forward. Raise the saw blade just above the
surface of the table by turning the elevating handle.
(iv)
Now release the rip locating slide bar and the yoke
clamp and then rotate the yoke 90° so that the blade
is facing the fence and lock it into that position with
the slide bar and the yoke clamp. Then push the saw
carriage backwards until the blade is resting against
the fence.
If the blade is completely flat, across its face against
the fence, this will confirm that the saw will perform
accurate parallel rip cutting.
