07 - 2 RT60 Rough Terrain Crane
7. 2 STARTING THE ENGINE
Start the engine only after the inspection has been completed. At ambient temperature
over 0℃ (32℉), follow the starting procedure below:
a) Move the transmission shift lever to the neutral position;
b) Put the parking brake switch in the “ON” position;
c) Turn the ignition switch to the “ON” position;
d) Turn the ignition switch to the “START” position to start the engine.
Release the ignition switch key as soon as the engine starts. If the engine stalls during the
start-up procedure, allow the engine to stop running before restarting the starter.
Do not engage the starter motor for more than 15 seconds at a time. Should the engine fail
to start within 15 seconds, allow the starter motor to cool for 2 minutes before attempting to
start the engine again.
Once the engine is started, check the gauges for proper readings. If the gauges do not
register normal readings, stop the engine and determine the cause. Avoid full Throttle
operation when the engine is cold. Always allow the engine to reach normal operating
temperature before commencing operations.
7. 3 OPERATING THE ENGINE
When the engine reaches operating temperature, operations may begin. While the engine
is running, check the gauges at frequent intervals and be alert for any abnormal engine
sounds or faulty engine performance.
When idling for extended periods, maintain an idle speed sufficient to prevent the battery
from being discharged. Keeping the battery in a fully charged state is important for starting
the engine.
Throttle down to half speed or slower with no load for at least 5 minutes before stopping.
This gives the engine a chance to cool off gradually before it is stopped.
This cool down period is extremely critical on machines equipped with
turbocharged engines due to the excessive build up of heat during normal load
operations.
Consult the engine manufacturer’s manual for further operating instructions.
7. 4 COLD WEATHER STARTING
At very low temperatures, when the engine is difficult to start, an optional flame starting
device is very important to help the normal engine start. Please contact Zoomlion Service
Department if you want to select a flame starting device for your crane.
