Connecting a DC power cord
1.
Use a screwdriver to loosen the screws on the protection cover over the power receptacle and
then remove the cover.
2.

The receptacle is foolproof. If you cannot insert the connector into the receptacle, re-orient the
connector rather than use excessive force to push it in.
3.
Fasten the captive screws on the power cord connector with a screwdriver to secure the power
cord connector.
4.
Use a cable tie to secure the power cord to the handle.
5.
Connect the other end of the power cord to a DC power source.
