Bissell 7950 Owner’s Manual

BISSELL SELF PROPELLED UDC - MODEL 7950

Highlights of the new model

The main differences between the self propelled UDC and the
standard UDC occurs in the Upper and Lower Handle Assemblies.

The Lower Handle Assembly contains a Transmission/Motor
Assembly with Belt Drtve, Rectifier/Terminal Board, and Neutral

Knob. The transmission motor is 110 volt DC.

The Neutral Knob-is the mechanism used to engage and disengage
the transmission for use. To move the unit without the use of the

transmission, the Neutral Knob must be in the "OFF" position.

The Lower Handle also contains the Heater and Trigger Valve
Assembly. The Trigger Valve Assembly has tubes that are of

different length than other Bissell UDC models. The Trigger Valve
Assembly is not interchangeable with standard models (non self

propelled).

The Upper Handle Assembly contains the "ON" - "OFF" switches for

both the unit's Power and the Heater. If the need arises to change
out the Lower Handle Assembly wire harness, it is recommended that
the Upper Handle Harness be changed out also. The two wiring

harnesses are supplied as a single replacement kit.

The wheels are new and are not interchangeable with other models

The tube routing and components have remained the same in the

foot assembly. The pump, motor, base, brush assembly, etc. are the

same as in the standard models.

The Tool Caddy on the 7950 is different than on the standard models.
