Tensioning and tracking the blade
Make sure both top and bottom blade guide
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 page 13. For
tracking the blade first adjust all bearing guides so
that they’re well clear of the blade. Check that the
blade is sitting approximately in the middle of the
wheels, see fig 12.
Apply some tension to the blade by turning the
tensioning wheel clockwise. Spin the top wheel by
hand, and check that the blade remains centrally on
the tyre, see fig 13. If it does not, loosen the tracking
control lock and adjust the tracking by turning the
tracking control at the rear of the upper saw wheel
compartment, see fig 14. 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 on the blade should
allow a maximum of 1 centimetre of movement
with moderate pressure on the blade. Check the
tracking again, adjust if necessary.
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)
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. Retighten
the tracking control lock.
