This includes information on keeping the motor clean and free of dust, maintaining the

Note: During assembly at Castle, the front housing of the drill motor is rotated 90 degrees
to orient the power cord straight down relative to the T-Knob bolt hole. Replacement
motors obtained through sources other than Castle may need to have the front
housing rotated similarly.
