4.2 GENERAL
This section provides the necessary information needed

4.3 ENGINE OPERATION
IMPORTANT
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 230
DEGREES F (111 DEGREES C). 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 OPERATION.
NOTE: Initial starting should always be performed from the
Ground Control Station.
Starting Procedure
1. Check engine oil before attempting to start engine; if
necessary, add oil in accordance with Engine Manu-
facturers Manual.
2. Pull the red mushroom-type Ignition/Emergency
Stop switch at the Ground Control Station to the UP
position (ON).
3. Place the PLATFORM/GROUND SELECT switch to
the applicable position for desired control station
operation.
4. If operating a dual fuel machine, place the LP/GAS-
OLINE SELECT switch to the desired position.
NOTE: If LPG system is selected, ensure that the hand
valve on the LPG supply tank is opened prior to
attempting to start the engine.
IMPORTANT
IF ENGINE FAILS TO START PROMPTLY, DO NOT CRANK FOR AN
EXTENDED PERIOD. SHOULD ENGINE FAIL TO START ONCE
AGAIN, ALLOW STARTER TO “COOL OFF” FOR 2 TO 3 MINUTES.
IF ENGINE FAILS TO START AFTER SEVERAL ATTEMPTS, REFER
TO ENGINE MAINTENANCE MANUAL.
NOTE: If starting machine from the platform control station,
place the engine speed control switch to the LOW
position prior to starting the engine.
5. If starting machine from ground controls, position
IGNITION/EMERGENCY STOP switch to ON and
depress START button and hold until engine starts.
If starting from platform controls, position POWER
ON switch to ON and depress START button and
hold until engine starts.
6. Check engine voltmeter when starting engine and
monitor gauge periodically during operation.
IMPORTANT
ALLOW ENGINE TO WARM-UP FOR A FEW MINUTES AT LOW
SPEED BEFORE APPLYING ANY LOAD.
7. After engine has had sufficient time to warm up, pro-
ceed with operation of unit.
