Tools and Parts Required to Provide Power to the T640 Router
To provide power to the router, you need:
•
DC-powered routers: 7/16-in. (11 mm) hexagonal-head external drive socket wrench,
or nut driver, with a torque range between 23 lb-in. (2.6 Nm) and 25 lb-in. (2.8 Nm),
for tightening nuts to terminal studs on each power supply on a DC-powered router.
CAUTION: You must use an appropriate torque-controlled tool to tighten
the nuts. Applying excessive torque damages the terminal studs and the
power supply. The absolute maximum torque that may be applied to this
nut is 45 lb-in. (5.0 Nm).
