Do not perform any maintenance unless the procedures are covered in this manual. Always follow all safety
precautions. Read and understand the Safety section of this manual before proceeding with any inspection or
maintenance procedures. See “Maintenance Safety” on page
Checks Before Maintenance
Review the Maintenance Log and follow these points:
•
Avoid working on the machine while the engine is running unless required to do so in the procedure. If the
engine must remain running during a procedure, always have a person in the cab who can correctly operate
the machine and who is in clear contact with you at all times.
•
Contact a SANY dealer if you are unable to perform the procedures listed in this manual or if additional
procedures are required.
•
Always use the proper tools when performing any maintenance procedures.
Checks After Maintenance or Repairs
Before starting the machine after maintenance or repairs, verify the following:
•
If necessary, have a coworker inspect your work for correct and proper completion.
•
Complete the Maintenance Log.
•
Check for leaks in the system that had maintenance or repairs.
•
Verify there are no abnormal sounds coming from the engine or hydraulic system.
•
Check for any loose or abnormal movement in the system you have maintained.
•
Check for any overheating in the system you have maintained.
After performing maintenance or repairs to the machine, always take time to inventory your tools, parts used, and
fasteners to be sure none of these items were left on or inside the machine. Return the machine to its proper
location.
Hour Meter Reading
Record the hour meter reading (on the monitor home screen) on a daily basis. Confirm hour meter readings with
the required maintenance intervals listed in this manual. See “Monitor” on page 3-4.
Genuine SANY Parts
Use genuine SANY replacement parts when repairing or replacing machine components. Failure to do so may
result in premature system or part failure.
