FOOT OPERATED BRAKE ADJUSTMENT
Grubscrew marked "A" Fig. 6 is initially set to
depress micro-switch when foot pedal is operated
to its full extent. Failure of brake pedal to return
will prevent machine being started, check spring
for fatigue and replace if necessary.
To replace micro-switch; isolate machine, remove
switch, disconnect electrical leads, connect new
switch and
replace switch on facing. Start machine
and
ensure that when brake pedal arm is depressed
to its full extent the micro-switch is operated by
the
grubscrew marked "A".
FENCES, TABLE AND GUARDS.
"A"
To set canting ripping fence for cutting. Move fence to approximate position required. Operate
first lock by rotating clockwise, fine adjust to obtain correct dimension required. Operate
secondary lock, this also squares fence to dovetail groove. To unlock fence operate first lock
in
anti-clockwise direction until dead stop is reached, secondary lock need not be operated.
CANTING RIPPING FENCE
LOCKING ADJUSTMENT
Should the fence secondary lock not
operate the two hexegon head screws
(on the right hand side of the fence
base) should be slackened off and
the
three grubscrews rotated clock-
wise each by the same amount until
the
eccentric secondary lock holds
the fence
in the required position
after operating the first lock.

than at the front of the saw. Should this pitching require
altering the grubscrew locking the eccentric pivot pin,
should be slackened off and the eccentric pivot pin turned
so as to increase or decrease the pitching.
To
adjust the fence pointer measure dimension between
set of saw nearest fence and fence plate, then slacken
off pOinter locking grubscrew, set pointer to dimension
obtained between Saw set and fence, lock pointer in
position.
DOUBLE MITRE FENCE. Fig. 8. is in two parts
both made to pivot from a central pin fixed in
sliding table. Degree angles are marked on the
table for accurately setting the fences, the principal
angles being positively located by spring plunger.
Mitres can be cut giving accurately squared frames
when assembled a bar and stop determines the exact
length of material cut off. Front leaf is supplied as
standard,rear leaf optional extra.
Cross cutting fence Fig. 9. is used for both square
and angular work and can be used either side of the
saw in the table grooves. A bar and stop determines
exact length of material cut off. This fence is an
optional extra.
