2.2.3 Start of engine
Initial position before starting
Set the operating elements to their initial posi-
tion prior to the start of the engine.
• Engine speed (504).............................MIN
• Driving lever (501).......................CENTRE
• Vibration (312) ..................................OFF
• Parking brake (304) ...................APPLIED
• EMERGENCY STOP
(NOT-STOP) (302)...............................UP
Start of engine
• Engine speed (504)................... ¼ to MAX
• Key switch (310) ...............................0 → I
(Electrical system ON)
When the key switch is turned to position I, all
illuminated indicators light up shortly for func-
tion control purposes.
• Key switch........................................I → III
When the engine is running,
• the illuminated indicator for charging cur-
rent (201)
• the illuminated indicator for engine oil
pressure (202)
must go out.
Danger of intoxication!
Combustion engines and fuel-operated
heating systems may only be operated in
sufficiently ventilated areas. Take care for
sufficient ventilation prior to starting.
Engine starting with maximum engine
speed can lead to engine damage or dam-
age at the hydraulic system.
The starting process may last 20 seconds
as a maximum; otherwise, the starter will
be overheated and destroyed. There must
be pauses between the individual starting
processes in order to allow the starter to
cool down. If the engine doesn't start after
two starting attempts, find out and elimi-
nate the cause. Observe the instruction
manual of the engine.
The engine cannot be started by towing,
because the hydrostatic drive acts as a
brake when the feeding pressure is miss-
ing. Drive component damage would be
the consequence.
Only when the driving lever is in centre po-
sition, is the start connected to the key
switch via the starter protection device.
This is the only way to start the engine.
