Service
The following general suggestions should
be helpful in analyzing and servicing your
crane. Using the following systematic
approach should be helpful in finding and
fixing problems:
1. Determine the problem.
2. List and record possible causes.
3. Devise checks.
4. Conduct checks in a logical order to
determine the cause.
5. Consider the remaining service life of
components against the cost of parts
and labor necessary to replace them.
6. Make the necessary repair.
7. Recheck to ensure that nothing has
been overlooked.
8. Functionally test the new part in its
system.
Stellar Industries recommends the first
filter change to occur after the first 250
hours of service.* The second, and
every subsequent change, should
occur after every 1,000 hours of
service. By following these guidelines,
the hydraulic oil should last up to
6,500 hours.
*Note: These recommendations are based on normal
working parameters. If operating in less than favorable
conditions (excessive dust, moisture, etc.), be sure to check
the filter gauge often for filter change notice.
Inspection Checklist
For a more detailed outline of scheduled
inspection points, refer to the Stellar
Inspection Checklist at the end of this
chapter. This list is an excellent guide for the
inspection tasks that will help maintain the
quality of your Stellar product. Feel free to
photocopy the checklist as needed.
ATTENTION
Every six (6) months, remove the
hydraulic pump from the PTO and
lubricate the splines using Chelsea
Lubricant #379831 or Stellar PN 20885.
Failure to lubricate shaft splines will cause
damage to the PTO and Hydraulic pump.
