Terminal Fig. D-3

Before installing Switch in Housing R, route Lead wires as illustrated below and connect two Connectors. Do not put their Lead wires on the ribs of Housing L. Lead wire holders Housing L Connector (To Switch) Connector Lead wires have to fixed with the ribs. Fig. D-4 Bend the terminals of DC motor as illustrated. Route Lead wires between ribs. Insert Connectors between their Lead wire holders. Lead wires in this area must be tight. LED
Flag receptacles and Lead wires have to be far from DC motor. Do not put them on the ribs.
Fix Lead wires with Lead wire holders.
Face the glue-attached portion of LED downward.
Lead wires between Connector and Switch have to be placed behind Switch.
Do not ride Lead wires on the screw embosses.
