Collect Hydraulic Oil Sample
1. Obtain an Oil Analysis Sample Kit from a SANY
dealer.
2. Operate the machine until the hydraulic oil is up to
normal operating temperature.
3. Prepare the machine for service. See “Maintenance
Safety” on page 2-5.
NOTICE!
It is critical that all material used to collect the
sample is absolutely clean. Failure to adhere to
this warning can cause equipment damage and
contaminate the sample.
4. Remove the hydraulic oil return filter cover. See
“Replace the Hydraulic Oil Return Filter” on
page 5-34.
5. Insert the oil sample tube into the hydraulic tank and
collect a sample of hydraulic oil.
6. Install the hydraulic oil return filter cover.
Send the sample for testing in accordance with the
instructions packaged with the sample kit.
Change the Hydraulic Oil
WARNING
• Allow the hydraulic system to cool before
servicing. Hot oil may cause burns or other
serious injury.
• The hydraulic tank may be under pressure, and
hydraulic oil may be present at the filler cap.
Relieve any pressure to prevent injury.
Failure to follow this warning could result in death
or serious injury.
NOTICE!
• If the hydraulic oil is contaminated (discolored or
containing debris), collect an oil sample for
testing. Find and correct the cause of the
contamination before changing the hydraulic oil.
• Dispose of the hydraulic oil and filters in
accordance with all applicable environmental
regulations.
Failure to do so could result in damage to the
environment.
NOTES:
• Always use the same type and grade of hydraulic oil.
• Hydraulic oil deteriorates faster on machines
equipped with a hydraulic breaker than on machines
equipped with a bucket.
1. Prepare the machine for service. See “Maintenance
Safety” on page 2-5.
