If the battery indicator does not light up, first check
whether the fuse has blown. If the fuse has been re-
placed with a new one and is working normally, the
battery may be flat and may need to be recharged. If
the fuse still blows after replacement, the circuit must
be repaired by professional maintenance personnel.
Hour counter
The hour counter shows the total operating hours of
the excavator.
Reading the counter
The counter counts up by 1 for each hour of opera-
tion. The electrical counter continues when the en-
gine stops and the key is still in the "ON" position.
11.2 Checkpoints after starting the engine
Check the following points after starting the engine,
but before starting work:
1. Move the throttle lever to the "LOW" position and
allow the engine to idle for approx. 5 minutes. This
warms up the engine oil and allows it to penetrate
all parts of the engine.
Note: This operation in idle mode is usually
called "warming up".
2. After the engine has warmed up, check as follows:
• The "Battery charge" warning light goes out when
the engine accelerates.
• The colour of the exhaust gases is normal and no
abnormal noises or vibrations can be heard.
• No liquid escapes from the pipes or hoses.
Stop the engine immediately if any of the follow-
ing circumstances occur:
• The speed of the engine suddenly increases or de-
creases.
• Sudden abnormal noises.
• The exhaust fumes are black.
m Attention
In these cases, the excavator must be checked
and maintained in accordance with the dealer's
instructions.
11.3 Starting the engine when cold
m Attention
Ensure that the safety lever is locked during
warm-up.
1. Pull the throttle lever out by 1/3.
2. Pull the air regulator handle back down and the
start key to "ON" for five seconds to start.
When the petrol engine starts, the left-hand air
regulator handle resets. (Note that the petrol en-
gine can be started when the vehicle is warm
without pulling the air regulator handle).
3. Release the key when the engine has started. It
automatically returns to the "ON" position.
Note: After starting the engine, allow it to warm up
for about 10 minutes without load. If the tempera-

someone could accidentally touch the levers and
cause serious accidents. Lower all attachments
to the ground, otherwise accidents may occur.
Allow the engine to idle for about 5 minutes to cool down.
1. Move the throttle lever to the idle position.
2. Carefully lower the attachments to the ground us-
ing the levers.
3. To stop the engine, turn the key to the "OFF" posi-
tion and remove the key.
11.5 Shutting the petrol valve
m Caution
In an emergency or if the engine is still running
when idling and the key is in the "OFF" position,
proceed as follows.

and hold it until the engine stops.
