Ammann AV 70 X - Start-Up of the Engine

61AV 70 X
OPERATION MANUAL
2.7.1. Start-up of the engine
Check daily before engine starting the amount of oil in the engine and hydraulic tank, cooling liquid in the cooling circuit, fuel in fuel
tank, water level in water tank. Conrm no loosened, worn or missing parts exist on the Machine.
Start the engine only from the driver’s control stand! Use alarm horn to signal the engine starting and
check nobody is endangered by starting the engine!
How to start:
Switch ON the battery disconnector (51).
•
Insert key in the ignition box (12) in “0” position and switch over to “I” position.
•
All indicator lamps on clusters (25 and 26) will light up.
•
Then on cluster (25) the indicator lamps for brakes, recharging, neutral, will remain ON, along with engine lubrication indicator
•
lamp (ickers).
If you leave the key in ”I“ position for over 15 seconds then the acoustic alarm will switch ON – to warn operator about the battery
•
discharged (acoustic alarm will turn OFF once engine is started). Unless it is started within 2 minutes, please get your key back to
“0” position before starting the engine again.
Use alarm horn on combined switch (17) to signal engine starting.
•
Adjust accelerator control (13) for increased rpm (1/4 stroke).
•
Switch over the key to the suspended position “II” and keep it at the position for approximately 15 seconds (engine heating) (this
•
action can be skipped with a hot engine or at a high ambient temperature).
Turn the key to “III” position to start the engine.
•
On cluster (25), following the starting, the engine lubrication indicator lamp and recharging indicator lamp shall go OFF.
•
Once the Machine has started to move the neutral lamp and brake lamp will go OFF.
•
Note
If starting is unsuccessful, please turn your key back to ”0“ position. Unless engine starts even after 3 attempts – please check the oil
system.
Starting is interlocked:
unless travel controls (1) are in neutral position (N)
-
emergency brake (8) function is enabled.
-
Do NOT start the engine for over 30 seconds. Wait 2 minutes before any next starting.
When starting at low temperatures the recharge indicator lamp will remain ON accompanied by a sound
alarm – increase engine rpm adequately – the indicator lamp will go OFF.
Following the engine start let the engine idle at increased rpm (1/2 stroke of accelerator actuator) for
3÷5 min.
Steep rpm increase or decrease is inadmissible – it may damage the engine.
Do NOT let the engine idle for over 10 minutes – any idling longer then that may cause fouling of injec-
tors, piston rings, or valves to get seized!
Unless oil temperature reaches min. 60 °C, then the engine will not be lubricated suciently – do not
load the engine fully!
