SETUP/ADJUSTMENT

Tensioning and Tracking the Blade
Make sure both top and bottom blade guides
are clear of the blade
Open the upper and lower wheel doors, giving good access
to the saw wheels. To tracking the blade first adjust all guide
bearings so they are clear of the blade, see fig 03.
Fig 03
Check that the blade is sitting approximately in the middle of
the wheel. Apply some tension to the blade by turning the
tensioning wheel clockwise, see fig 04-05 spin the top wheel
by hand and check that the blade remains centrally on the tyre.
Fig 04
If it does not, adjust the tracking by turning the tracking control
at the rear of the head box, see fig 05. 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.
Continue until the blade tracks in the centre of the tyres with
no appreciable to and fro movement.
Tighten the tracking control knob 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.

locking bolts (C) and turn the tensioning bolt (D) to press
down the motor until the belt is under tension then
re-tighten the bolts (C) to lock the motor in position, see fig 06.
