• If the ambient temperature is expected to drop
below 32°F (0°C), check the engine coolant mixture
ratios and add concentrated engine coolant to the
cooling system if necessary.
• Close and lock all doors.
During Storage
During the storage period, operate the machine on a
monthly basis to prevent rust and seizing of moving parts
and to lubricate the seals. Charge the battery at this time.
After operating the machine perform the following
procedures:
• Extend the bucket, arm, and boom and support the
dozer blade on a block.
• Apply a thin layer of grease to any exposed surfaces
of the hydraulic cylinder rods.
• Disconnect the negative battery cables or remove
the batteries from the machine. See “Replace the
Batteries” on page 5-37.
• Close and lock all doors.
Return to Service
Follow the procedures below before using a machine that
has been stored for a prolonged period of time:
• Clean the grease from the cylinder rods.
• Add oil or apply lubricant to all parts or components.
• Check the fuel and engine oil for contamination.
• Examine the exterior of the machine for signs of rust
or damage. Repair or replace as necessary.
• Start the machine and test all operations.

Transportation Information
Transportation Method
Applicable laws and regulations must be observed when
transporting the machine.
• When transporting the machine on a trailer, confirm
the length, width, height, and weight capacity of the
trailer before loading.
• Investigate the road conditions in advance (for
example, dimension restrictions, weight restrictions,
and traffic regulations).
• The machine may need to be disassembled to meet
the local dimension and/or weight limits.
NOTE: The machine’s shipping weight and dimensions
may vary depending on its tracks and work
equipment.
Loading and Unloading
WARNING
• To prevent the machine from tipping over, select
a firm and level location that is a safe distance
from any road or structure.
• Make sure the trailer is properly chocked to
prevent any movement.
• Use an access ramp with enough length,
strength, and width to properly support the
machine. The ramp grade should not exceed 15°.
• Drive slowly at the junction of the ramp and the
trailer. The machine may shift suddenly due to a
change in its center of gravity.
• Use a signalman to alert the operator to any
potential hazards.
Failure to follow these warnings could result in
death or serious injury.
• Deactivate the auto-idle mode before loading or
unloading; otherwise, the machine may move
suddenly.
