Oil Sampling Procedure - Kohler SFGLD480 Operation & Maintenance Manual

1. OBJECT
This Product Information sheet clearly specifies a procedure for collecting oil samples from all Kohler engines,
for their subsequent analyses.
2. SAMPLING ROCEDURE
The oil sample for analysis must be representative of the entire operating load. Therefore, always do the
-
sampling when oil is circulating in the engine, since this ensures product homogenization.
- When collecting oil, take great care to avoid external contamination. In particular, check that the sample
containers are perfectly clean and dry.
- You may sample oil during an oil change, but bear in mind that you should not take samples at the beginning
or end of the oil sump draining process.
To take samples for analysing the oil condition when there is a sampling valve (unit ref. 31.25.920) available,
-
remove the cap from the sampling valve.
Where there is no such sampling valve available, we recommend sampling on a pressure oil line or, failing
-
this, direct from the oil sump.
NEVER take samples from the first jet of oil coming out when you open the sampling valve; always drain
-
about 400ml of oil to eliminate any contaminating residues present in the circuit. When done, reset the valve
cap.
- Finally, stick a label on the sample, stating all the relevant data: date, engine, type of oil, operating time of
engine, operating time of oil, engine oil consumption.
