Warning!
The gear selection knob may not be operated
before first disconnecting the two
power cords from the saw. This important rule must always be strictly followed to ensure that
the blade motor cannot be inadvertently started. Failure to follow this instruction may result in
serious personal injury or death.
The power pack can be placed out of sight of the operator, maybe 30 m’s away, or on a
different level, and the only way to protect the operator from accidental starting of the blade
motor is for the operator to always disconnect the two power cords. With these cords
disconnected no power can go to the saw head.

Depending on what size of blade you are using, you achieve a suitable peripheral cutting speed by choosing the
correct gear.
You can use the potentiometer to adjust the speed continously (alteratiion of the frequency - Hz to the motor).
* With the first version of the remote control, the scale for the blade potentiometer is from 0-100%. The setting for
440Hz is then 100%
