OPERATION
Use the cold starting aid only during starting and with the
engine cold.
REMARK
Never operate the starter longer than 30 seconds at a time in
order to avoid damage. If the engine does not start within the first
30 seconds, wait 2 minutes before cranking again. As soon as the
engines are running, check display (3) for messages.
7b. Cold Weather Starting at ambient Temperatures below
–25°C and to –40°C
When starting the engine at such extremely low tempera-
tures, it is vital to proceed according to the following start-up
procedure. The reliability of the machine and equipment will
be seriously impaired if the following procedure is not prop-
erly carried out
1. Record the Outside Ambient Temperature. If it is colder than
–40°C, then DO NOT start the Machine and keep the elec-
trical preheating systems activated.
If the customer decides to start the machine at temperatures
below –40°C it will be at the customer's own risks in terms of
potential structural damages and components failures. It must
be understood, that KMG will decline any warranty claims
which would result from starting or operating the machine
when the ambient temperatures are below –40°C.
2. If the Outside Ambient Temperature is between –40°C and
–25°C, then check that the preheating systems are duly ener-
gized and that all the heaters are functioning properly. Also
close the radiator shutters (if so equipped).
3. Let the preheating systems warm the hydraulic oil and the
engine coolant up to a temperature of –25°C or warmer.
These temperatures are indicated on the temperature gauges
on the dashboard.
(With Heaters properly functioning, these temperatures
should never fall below –25°C).
3.1. If the preheating systems were not energized during the
Standstill Period, the warm-up phase may last several hours,
depending on the actual ambient temperature the shovel was
exposed to, and the length of time the shovel stood still, until the
minimum starting temperature of –25°C for the hydraulic oil and
engine coolant is reached.
