4.1.7. Adjust new blade to the correct tension (see 4.2.) and check, and adjust if necessary, tracking (see 4.3.) and blade guide adjustment (see 4.5.).
4.1.8. Reinstall the blade guard, the table aligning pin and the side guide.
4.1.9. Close both blade covers and tighten retaining knobs.
4.2.
Adjusting blade tension
4.2.1. Open blade covers and ensure that blade is centred on both wheel rims.
4.2.2. Turn the blade tension knob (fig.3.H) - clockwise to tighten,
anticlockwise to slacken - to adjust the blade tension. Correct
tension is reached when the blade give s s l i g h tly to firm
finger pressure at mid-span. Do not over-tighten.
4.2.3. Close both blade covers and tighten retaining knobs.
4.3.
Adjusting blade tracking
4.3.1. Open blade covers and carefully rotate upper wheel clockwise,
by hand, to determine whether blade is tracking correctly - on the
centre of each wheel rim.
4.3.2. If adjustment is needed, turn the tracking knob (fig.3.I) whilst
continuing to turning the upper blade wheel. Note the effect on
the tracking and adjust tracking knob until tracking is correct.
4.3.3. Close both blade covers and tighten retaining knobs.
4.4.
Upper blade guide position
4.4.1. The upper blade guide should always be adjusted to about 3mm (1/8") above
the workpiece. To adjust, loosen the adjusting knob (fig.3.G) and move the
assembly to the required position. Tighten adjusting knob.
4.5.
Upper and lower blade guide adjustment
4.5.1. Remove the upper blade guard from the upper blade guide by undoing
screws (fig.4.A).
4.5.2. Loosen clamp screws (fig.4.B) on upper and lower guides (fig.5.A).
Rotate shafts of upper guide bearings (fig.4.C) so that bearings do not touch
blade and pull lower guides (fig.5.B) away from the blade.
4.5.3. The upper blade support bearing (fig.4.D) prevents the saw blade from
being pushed too far back when cutting. It should be adjusted to
0.75mm (1/32") behind the blade by loosening the screws (fig.4.F),
positioning the bearing and then tightening the screws.
4.5.4. Loosen screw (fig.4.E) and adjust support bearing (fig.4.D) so that centre of bearing race is in line with blade.
4.5.5. Adjust the upper guide bearings (fig.4.C) so that each is just clear of the side of the blade and the bearing edges are just behind the
roots of the blade teeth. Tighten the clamp screws (fig.4.B).
4.5.6. Adjust the lower guide bearings (fig.5.B) so that each is just clear of the side of the
blade. Tighten the clamp screws (fig.5.A).
4.5.7. Loosen screws (fig.5.C) and move the guide bracket in or out until the front edges
of the guides are just behind the teeth roots. Tighten screws.
4.5.8. Adjust the lower blade support bearing to 0.75mm (1/32") behind the blade by
loosening screw (fig.7.D). When adjustment is correct retighten screw.
Notes: a) Always check and adjust both upper and lower guides at the same time.
b) Always carry out these checks/adjustments every time the blade is changed.
c) The blade will be damaged if the teeth contact the guides/guide bearings.
4.6.
Drive belt
4.6.1. Open lower blade cover and check belt tension. Belt should have approx. 5mm mid-span deflection under finger pressure.
4.6.2. To adjust belt tension turn tension handle (fig.3.L).
4.7.
Blade speed
4.7.1. Open lower blade cover and remove all belt tension
by turning tension knob (fig.3.L).
4.7.2. Move belt to the required pair of pulleys. See fig.6.
4.7.3. Tension belt (see 4.6.) and close cover.
4.8.
Mitre gauge
4.8.1. The mitre gauge (fig.3.K), which locates in either of the two table slots, is adjustable through 60
locking knob, adjust and then tighten locking knob.The two knobs (fig.3.M) allow the mitre fence to be adjusted with respect to the angle plate.
4.9.
Fence
4.9.1. The fence (fig.3.J) is mounted on the table side guide (fig.3.B). Fig.7 shows the
relationship between the fence mount (A), ,the clamp plate (B) and the side guide (C).
4.9.2. To reposition, or remove, fence loosen lock knob (fig.3.N). Retighten when fence is in new position.
4.9.3. Loosen knobs (fig.3.O) to reposition fence with respect to the fence mount. Retighten.
