Make sure both top and bottom blade guides are
well clear of the blade.
Open the front covers fully, giving good access to the
top compartment of the saw and good visibility into
the bottom compartment (see fig 10). Check that the
blade is sitting approximately in the middle of the
wheels. Apply some tension to the blade by turning
the tensioning wheel clockwise, spin the top wheel
and check that the blade remains centrally on the
tyre, if it does not, adjust the tracking by turning the
tracking control at the rear of the head box (see fig
9). (Viewed directly onto the tracking control wheel,
turning clockwise should cause the blade to track to
the rear of the tyre, anti-clockwise to the front, DO
NOT make large adjustments).
Spin the top wheel again, check again. Continue
until the blade tracks in the centre of the tyres with
no appreciable to and fro movement. Tension the
blade fully. (A sideways push of about 7-8 lbs(3+kgs)
in the middle of the blade should allow a 1/4” -
,(6.5mm) distension). Check the tracking again, adjust
if necessary. Check that the drive belt is tensioned
correctly, if it is slack, apply ‘take up’ pressure to the
belt by adjusting the ‘idler’ pulley, using the knob at
the side of the machine.(See fig 10).
Connect the power to the machine. Stand clear and
start the saw, check that the saw is running smoothly,
(no thumps, bumps, knocking or excessive vibration)
Loosen the butterfly nut clamping the tilt
mechanism, and turn the table hard against its
stop. (This is a bolt with a lock nut screwed into the
underside of the table, (See figs 11 & 11a), the head
of the bolt acts as a stop when it strikes the machine
frame). Tighten the butterfly nut. Make sure the upper
blade guide is raised as high as possible. Place a
square on the table and move it up against the blade
(behind the teeth).
Check that the blade is perpendicular to the table. If
it is not, try resetting the table. If it is still not correct,
loosen the locking nut and adjust the bolt until
perpendicularity is achieved, tighten the lock nut and
then re-check. When you are satisfied that the table is
set correctly, check that the pointer of the tilt gauge
reads zero, if not, adjust it.
and the blade appears to be tracking correctly (in
one place). You can check this by holding a marker,
e.g. a pencil, close to the back of the blade (approach
from the back of the blade only) and check that the
gap remains constant.
If it doesn’t, adjust the tracking until it does. (If you
adjust the tracking with the saw running, make very
small adjustments and wait for the saw to react
before you adjust again, sometimes the reaction is
not instantaneous). Once you are satisfied that the
tracking is correct switch the machine off and allow it
to run to a stop.
