Blade tracking
NOTE: Set the blade tension BEFORE making any tracking adjustments.
Check that the blade guides are not touching the blade.
• By hand, turn the upper blade wheel clockwise and watch the blade
position on the surface of the wheel. If the blade moves off centre,
tracking adjustment is required
• If the blade moves towards the Outside Edge of the blade wheel (H), turn
the Tracking Adjustment Knob (13) clockwise. Continue adjusting until the
blade returns to and remains in the centre of the blade wheel
• If the blade moves towards the Inside Edge of the blade wheel (J), turn
the Tracking Adjustment Knob (13) anti-clockwise. Continue adjusting
until the blade returns to and remains in the centre of the blade wheel
• Check the position of the blade on the lower wheel. If the tracking is off,
continue to adjust the Tracking Adjustment Knob (13) clockwise and anti-
clockwise until the blade is centred on both blade wheels as they rotate
Adjusting the upper blade guide stabilising bars and blade
guide bracket (Fig 5)
NOTE: The upper and lower blade guides and support bearings stabilise the
moving blade during operation under load conditions. These guides MUST
be checked and adjusted BEFORE EACH USE and AFTER BLADE CHANGES.
• Loosen the two Blade Guide Adjusting Screws (M) with a hex key. Slide
each blade guide stabilising bar towards the Blade (5) so that they are
as close as possible to the blade, but without touching or pinching the
blade. Tighten the two Blade Guide Adjusting Screws (M) securely with
the hex key
• Loosen the Blade Guide Bracket Adjusting Screw (N) with the hex key
• Move this bracket in or out until the front of the two blade guide
stabilising bars are to the rear of, and not touching, the blade teeth

the hex key
WARNING: ENSURE that the two blade guide stabilising bars do NOT
touch the teeth of the saw blade when you are operating the bandsaw and
applying pressure into the saw blade with your workpiece.
Adjusting the upper blade support bearing (Fig 5)
• The Blade Support Bearing (L) keeps the saw Blade (5) from being
pushed back when cutting. This support bearing should be fixed 3mm
behind the blade
• Loosen the Blade Support Bearing Adjustment Screw (K) with the hex
key. Position the Blade Support Bearing (L) 3mm behind the smooth, rear
edge of the blade
• Tighten the Support Bearing Adjustment Screw (K) securely with the
hex key
• Refit the Blade Guard (3) if no additional adjustments are required
Adjusting the lower blade guide stabilising bars, blade guide
and support bearing (Fig 6)
• Follow the same steps and sequence used when adjusting the upper
blade guide stabilising bars for adjusting the lower blade guide and
support bearing
• To access the blade guide adjusting screw and support bearing adjusting
screw, pass the hex key through the holes in the lower blade wheel
housing
NOTE: Make sure you have properly adjusted both the upper and lower
