Changing the Blade Speed
WARNING! Before changing the speed always
make sure the machine has been unplugged from
the electrical supply.
This Bandsaw has two blade speeds, low speed
and high speed.
The lower bandwheel (A--Fig.13) has two, integral,
multi-vee form pulleys and the motor shaft has a twin
multi-vee form pulley (B--Fig.13).
The multi-vee belt (C--Fig.13) passes around the
bandwheel pulley and the motor pulley. The belt
tension is released and applied by using the
cranked handle (D--Fig.13).
For the high speed, the belt should be fitted to the
rear pulley on both the motor and bandwheel. As
shown in Fig.13.
For the low speed, the belt should be fitted to the
front pulley on both the motor and bandwheel. As
shown in Fig.13.
