DISCONNECT THE SAW FROM THE MAINS SUPPLY
Work Place/Environment
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. 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 by hand, and check that the blade remains centrally on the
tyre, 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. (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 side ways 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 tension as follows:- loosen the pivot bolt at the bottom of the motor mounting
flange plate. Thoroughly loosen the clamping bolt above the motor. Tension the belt by
turning the motor away from the saw wheel pulley. When the belt is tensioned, tighten the
clamping bolt through the motor mounting flange plate to hold the motor in position, then
tighten the pivoting bolt, ensure both bolts are tightened securely. Do not overtighten.
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.
Checking the table is square
If the pre-set table stop has been fitted, proceed as follows:-
Loosen the butterfly nut clamping the tilt mechanism, and turn the table hard against its
stop. 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.
If the pre-set table stop has not been fitted proceed as follows:-
Loosen the butterfly nut clamping the tilt mechanism, and turn the table until the pointer on
the scale reads against the zero. 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, reset the
table, until perpendicularity is achieved, tighten the clamp mechanism 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. Forthwith you will need to set the table square against the scale,
but you do have the advantage of being able to tilt the table negatively, albeit only 5
degrees.
