Setting Up the Saw

DISCONNECT THE SAW
FROM THE MAINS SUPPLY!
Tensioning and tracking the blade
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 page 12). For tracking
the blade first adjust all bearing guides so that there
well clear of the blade. Check that the blade is sitting
approximately in the middle of the wheels, see fig
08. 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 09. If it does not, adjust the tracking
by turning the tracking control at the rear of the head
box, see fig 10. 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 11.
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. 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.
