Engine Shut Down
Mandatory Safety Shutdown Procedure
Before leaving the machine:
1. Bring the machine to a complete stop on a level
surface. Avoid parking on an incline or a hillside,
but if this is not possible, park across the slope.
2. Lower the working equipment to the ground and
support it securely.
3. Run the engine at idle speed for a few minutes to
allow systems to cool after operation at full speed.
4. Turn the key fully counter-clockwise to shut off the
engine. Wait for all movement to stop.
5. Move the joysticks in all directions to verify the
hydraulic system is de-pressurized.
6. Lock-out controls by raising left control console.
7. Remove the ignition key and take it with you. Exit
the machine using the hand-holds.
New Machine Break-in Procedure
A new machine requires reduced operational speed
during the first 50 operating hours to properly break in
various parts. If the machine is subjected to hard use
during the break-in period, damage to operating sys-
tems may occur.
Perform the following when operating a new machine:
•
Perform all steps in “Pre-Operation Checklist” on
page 3-28.
•
Start engine and let it idle for 10 - 15 minutes so all
components and systems can warm up.
•
Operate machine at about 80% of maximum loads
and speed.
•
At the end of the first 100 operational hours, drain
and replace the engine oil and engine oil filter.
Travel
WARNING
•
Before operating the travel levers, be
sure that you know in which direction
the machine is pointing. If the dozer
blade is not visible from the operator’s
cab, you are looking at the rear of the
machine and the travel controls will be
the reverse of normal operation.
•
Before moving, be sure that there are no
personnel in the way of the machine.
Sound the horn to alert workers that you
are about to move the machine.
•
Be sure the path is clear during travel.
•
Use extreme caution when reversing
travel. Be sure there is a clear path
behind the machine.
•
Operate the travel control levers
smoothly to avoid sudden starts and
stops.
•
Before leaving the operator’s seat, be
sure to lock out all control systems and
shut down the engine to avoid acciden-
tal activation.
