Choose a point on the machine; i.e., contact patch of a tire, as a visual reference for use when
crossing the start and finish lines.
Bring the machine to top drive speed before reaching the start line. Begin timing when your
reference point on the machine crosses the start line.
Continue at full speed and note the time when your reference point on the machine passes over
the finish line. Refer to specifications.
13 - Perform Hydraulic Oil Analysis
Tools will be required to perform this procedure.
New parts will be required to perform this procedure.
Dealer service will be required to perform this procedure.
This procedure is to be performed every 3 months or every 250 hours, whichever comes first.
Replacement or testing of the hydraulic oil is essential for good machine performance and service life.
Dirty oil may cause the machine to perform poorly and continued use may cause component damage.
Extremely dirty conditions may require oil changes to be performed more often.
Before replacing the hydraulic oil, the oil may be tested by an oil distributor for specific levels of
contamination to verify that changing the oil is necessary.
If the hydraulic oil is not replaced at the two year inspection, test the oil quarterly. Replace the oil
when it fails the test. See page 33 for Test or Replace the Hydraulic Oil.
14 - Inspect the Hydraulic Tank Cap Venting System
Tools will be required to perform this procedure.
This procedure is to be performed every 3 months or every 250 hours, whichever comes first.
Perform this procedure more often if dusty conditions exist.
A free-breathing hydraulic tank cap is essential for good machine performance and service life. A dirty
or clogged cap may cause the machine to perform poorly. Extremely dirty conditions may require that
the cap be inspected more often.
Open the cover.
Remove the breather cap from the hydraulic tank.
