DANGER Before lowering the attachments to the ground, make sure that the machine and the area around
it are clear of other people. Anyone on or close to the machine could fall and be crushed by the attachments,
or get caught in the linkages.
WARNING Secure all loose articles. Loose articles can fall and strike you or roll on the floor. You could
be knocked unconscious, or the controls could get jammed. If that happens you could lose control of the
machine.
CAUTION Machines installed with hose burst protection valves cannot have their attachments lowered with
the engine stopped. Start the engine and lower the attachments before doing the walk-around inspection.
1. Read the Operating in Low Temperatures or Operating in High Temperatures procedures in the Operation
section if you will be using the machine in very cold or very hot climates.
Refer to: Operation > Operating Environment (Page 142).
2. If the fuel tank was empty or if any part of the fuel system has been drained or disconnected, the fuel system
must be primed before you try to start the engine.
Refer to: Maintenance > Fuel System > General > Bleed (Page 209).
3. Lower the excavator bucket and dozer to the ground, if they are not already there. They will lower
themselves under their own weight when you operate the controls. Operate the controls carefully to control
the rate of descent.
Refer to: Operation > Operating Levers/Pedals (Page 96).
