The Tennant 7200's squeegee function rises when moving in reverse and lowers when moving forward due to an interlock system. When the operator engages the reverse contactor, the squeegee automatically rises to prevent damage or interference. When the operator disengages the reverse contactor and moves forward, the squeegee function resumes, lowering it back for operation.

The Tennant 7200's squeegee function rises when moving in reverse and lowers when moving forward due to an interlock system. When the operator engages the reverse contactor, the squeegee automatically rises to prevent damage or interference. When the operator disengages the reverse contactor and moves forward, the squeegee function resumes, lowering it back for operation.
