Long-Term Storage
Before Long-Term Storage
Perform the following procedures before storing the machine:
1. Clean and wash all components and park the machine
indoors. If indoor storage is not possible, park the
machine on a firm, level surface. Cover the machine if
possible.
2. Extend the bucket, arm, and boom.
3. Support the dozer blade on a block.
4. Fill the fuel tank, apply lubricant, and change the
engine oil before storage.
5. Apply a thin coat of grease to any exposed surfaces of
the hydraulic cylinder rods.
6. Disconnect the negative battery cable or remove the battery and store it.
7. 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.
8. Place the hydraulic lockout control lever in the locked (closed) position.
9. 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.
NOTICE!
Extend the bucket and arm and lower the boom to help prevent the cylinder rods from rusting.
WARNING!
When operating the machine indoors, open the windows and doors to provide proper
ventilation and avoid gas poisoning. Failure to follow this warning could result in death or
serious injury.
