Obtain the sample of the coolant as close as possible
to the recommended sampling interval. In order
to receive the full effect of S·O·S analysis, you
must establish a consistent trend of data. In order
to establish a pertinent history of data, perform
consistent samplings that are evenly spaced.
Supplies for collecting samples can be obtained from
your Caterpillar dealer.
Use the following guidelines for proper sampling of
the coolant:
•
Complete the information on the label for the
sampling bottle before you begin to take the
samples.
•
Keep the unused sampling bottles stored in plastic
bags.
•
Obtain coolant samples directly from the coolant
sample port. You should not obtain the samples
from any other location.
•
Keep the lids on empty sampling bottles until you
are ready to collect the sample.
•
Place the sampl
einthemailingtubeimmediately
after obtaining the sample in order to avoid
contamination.
•
Never collect samples from expansion bottles.
•
Never collec
t samples from the drain for a system.
Submit the sample for Level 1 analysis.
