TITLE: 49 CFR PART 571, FMVSS 101 - CONTROL LOCATION, IDENTIFICATION AND ILLUMINATION

ATTACHMT: ATTACHED TO LETTER DATED 07/30/74 TO P.K. KAMATH FROM RICHARD DYSON -- NHTSA; N40-30 [ZTV]; OPINION FILE REDBOOK (-); STANDARD 101

TEXT: Dear Mr. Dyson:

Oshkosh Truck Corporation, in many vehicles, incorporates two controls to stop the engine. One control designated as engine stop (electrical) is operated in normal use to shut off the engine, the other control designated as the emergency engine stop (mechanical cable) is used only in emergency to shut off the engine, should the normal engine stop fail.

It is our understanding that the standard 101 applies to the control for normal engine stop and not to the emergency engine stop control.

Please confirm our understanding and if you disagree, please clarify how the control is to be identified and illuminated.

Very truly yours,
