4.3 ENGINE OPERATION
NOTICE
RTS SERIES SCISSOR LIFTS MANUFACTURED AFTER AUGUST
26, 1996 ARE EQUIPPED WITH A HYDRAULIC OIL TEMPERATURE
SWITCH THAT SHUTS DOWN THE ENGINE WHEN THE HYDRAU-
LIC OIL REACHES A TEMPERATURE OF APPROXIMATELY 111˚C
(230˚F). THIS SHUT DOWN IS INTENDED TO PROTECT THE
HYDRAULIC SYSTEM AND ITS COMPONENTS FROM DAMAGE
DUE TO EXCESSIVE HEAT. HEAT MAY BUILD UP DUE TO
EXTENDED DRIVING, IN CONJUNCTION WITH HIGH AMBIENT
TEMPERATURES, ACTIVATING THIS SWITCH AND SHUTTING
DOWN THE MACHINE. IF THE MACHINE SHUTS DOWN, ALLOW
THE HYDRAULIC OIL TO COOL, THEN RESUME NORMAL OPERA-
TION.
NOTE: Initial starting should always be performed from the
Ground Control Station.
