Setting Up The Saw - Axminster Trade AT2552BE Original Instructions Manual

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 17). 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 53. Apply some tension to the blade by turning
the tensioning wheel clockwise, see fig 54 spin the top wheel by
hand and check that the blade remains centrally on the tyre, see
fig 55. If it does not, adjust the tracking by turning the tracking
control at the rear of the head box, see fig 56. 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. Push the tracking control lock up to lock the
setting. 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 loosening the motor
locking Hex bolt (A) and pushing down the motor assembly
until the belt is under tension. Then re-tighten the Hex bolt to
lock the motor in position, see fig 57-58.
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 complete stop.
