OPERATION
NOTICE
Before starting read the Engine Operation Manual.
Observe the instructions for starting the Engines.
After repairs on the Diesel engines or starter motors,
make sure that the ground cables are correctly con-
nected before starting the engines. Loose or missing
ground cables can cause fire, serious injury or death.
Start the engines from the operator's seat only. Never
attempt to start the engines by shorting across starter
terminals. This can cause fire, serious injury or death.
Before each starting make sure that all controls are in
neutral position.
Be sure to sound the signal horn before starting to make
your intention clear.
Before starting the engines and again before starting work,
pay attention to the hydraulic oil temperature. Refer to para-
graph "Hydraulic Oil Warm-up" in this section.
