7.5 Folding the bandsaw blade

Hold the bandsaw blade in one hand. Let it hang down
vertically and hold it to the floor with a foot. Turn your hand
through 360° (a complete circle), as you move it down towards
the floor.

7.6 Changing the Blade Speed

This band saw hast wo blade speeds:
- 370 m/min for hardwoods, some plastics and certain non
ferrous metals.
- 800 m/min for all other timber.
The lower bandwheel (C, Fig 28) has two Poly-V pulleys, the
motor has a Twin-Poly-V pulley (D).
The Poly-V-belt (E) passes around the bandwheel pulley, the
motor pulley and the plain tension roller (F). The belt tension is
released and applied by using the cranked handle (G), this
moves the tension roller and allows the speed to be changed.
To change the belt the lower bandwheel must be removed.
For the high speed the belt must be fitted to the rear pulley on
both the motor and bandwheel. As shown in Fig. 29.
