OPERATION
10.5 Once the hydraulic oil is close to working tempera-
ture swing over one track, raise the track off of the ground
with the attachment, and slowly rotate the raised track to
remove cold oil from the circuit. The running surfaces of
track pads must be unobstructed with dirt, mud, or other
debris. Once the track has been rotated in both directions
for a few minutes, lower the track and repeat the same
procedure with the opposite track.
11. Operate the Shovel normally but smoothly, avoiding shocks
and jerky movements, as hydraulic hoses may burst when the
outside ambient temperature is extremely low. Operators
must be more careful as temperature goes down to the limit
of –40°C.
REMARK
Continuous operation with low coolant temperature below
+60°C can damage the engine. To increase coolant temperature
switch on the heater blowers in the machinery house. Load the
hydraulic system.
