ASSEMBLY cont'd

5. Using a hexagon wrench turn the 90˚ position

stop ✼✌ Fig.27. until the set screw just touches

the frame.

6. Re-check squareness of the blade to the table

and re-adjust as necessary.

7. Now set the table tilt scale pointer ✽✌ Fig.28. to

line up with the zero mark on the tilt scale.

ADJUSTING THE BLADE GUIDES AND BACK UP

BEARING

NOTE: The upper and lower blade guides and back

up bearings support the bandsaw blade during

cutting operations. The guides and bearings should

be checked and adjusted whenever a different blade

is fitted.

1. The upper back up bearing ✾✌ Fig.29. should be

adjusted first. Loosen the hexagon set screw ✿✌

located to the side of the bearing.

2. Adjust the back up bearing to within 1.5mm (

of the blade and tighten the hexagon set screw.

Now repeat this exercise for the lower blade

guide assembly.

NOTE: The back up bearing supports the back

edge of the blade during a cutting operation. The

blade should NOT be in contact with the

bearings when you stop cutting.

3. Next adjust the position of the upper blade guide

support ❀✌ Fig.30. Loosen set screw ❁✌ and

slide the blade guide support along until the

front edge of the blade guides are 1.5mm (

behind the gullet of the blade. Tighten the set

screw.

4. Repeat this exercise for the lower blade guide.

IMPORTANT: The blade will be damaged if the

blade teeth hit the blade guides whilst the

bandsaw is operating. Correct adjustment of the

upper and lower blade guards will prevent this

from happening.

Loosen the two hexagon screws ❂✌ Fig. 31. that lock

the upper blade guides ❃✌ and press both guides

gently against the sides of the blade. Do not pinch the

blade. Release the guides and rotate the upper wheel

slightly clockwise (moving the blade downwards

towards the table).

Check that one guide is not further away from the

blade than the other and tighten the hexagon screws

❂✌. Repeat this exercise for the lower blade guides.
