5.4 ADJUST THE BLADE GUIDE
5.5 CHANGE BLADE SPEED
- This bandsaw has two blade speed, lowe speed and
high speed.
- The lower wheel A has two, intergral, multi-vee form
pulleys and the motor shaft has a twin multi-vee form
pulley B.
- The multi-vee belt C passes around the wheel pulley
and the motor pulley. The belt tension is released and
applied by using the cranked handle D.
- For the high speed, the belt should be fitted to the rear
pulley on both the motor and wheel.
- For the low speed, the belt should be fitted to the front
pulley on both the motor and wheel.

To adjust the upper blade guides, first position the
roller guides relative to the blade by slackening off
the hex nut A and moving the guide carrier until
the roller guides are approx. 1/16" behind the
gullets of the blade. Next set the roller guides to
within 1/32" of the blade by releasing the screw B
on each side of the blade. Do not set the guides
too close as this will adversely affect the life
of the blade. Finally, adjust the thrust bearing to be
just clear of the back of the blade by unlocking the
hex nut C. When the correct adjustment is reached,
lock the thrust bearing in position with the hex nut A.
