! NOTICE !
The life of the electrical system will be greatly extended and
available machine torque increased by using the lower pulley
setting and keeping the motor speed up.
Machines purchased after mid-2003 have the speed reducer
pulley installed on the machine. A retrofit kit, part number 40-
300G, to add this feature to earlier machines is available from
the Smithy Sales Department at 1-800-476-4849 or at
