Oil sampling
Note!
•
The hydraulic system must be operated for a while before the oil sampling procedure is carried
out.
•
The oil must at all times meet the specification for actual type of oil used in the system. Take
oil samples regularly.
•
Follow the instructions regarding oil change intervals or the recommendations based on an oil
sample test.
The oil sampling points [1] can be located either on the upper housing port and stbd, upper
rear side of the valve block or on the filter housing, as illustrated in the picture.
1.
Locate the sampling point.
2.
Remove the protecting cap [2], as illustrated in the picture below. (The sampling plug
contain a non-return valve to prevent oil spill prior to connection of sampling hose.)
3.
Connect the sampling hose [3] to the sampling point.
4.
While the Steering gear is operated flush the hose by letting some of the oil run
through the hose and in to a bucket.
5.
Fill a clean sample bottle [4] with oil.
6.
Close the sample bottle and attach label to sample bottle indicating oil type, date,
sample taken by and oil used for how long.
7.
Compare sample with new oil by visual examination. If the oil colour has clearly
changed or impurities are present in the oil consider replacing the oil.
8.
Send the oil sample to be examined immediately.
