Section 3 - Maintenance and Servicing
This chapter describes the basic maintenance that is required for the 4262A, B, and C
Instruments. A troubleshooting guide is provided in the next section, in the event that
problems occur.
Maintenance
The 4262 Ultrasonic Cement Analyzer requires very little routine maintenance. Following the
recommendations listed below will allow years of trouble free operation.
•
Keep all test cell surfaces exposed to cement coated with a liberal layer of grease.
This reduces the chance of corrosion and prevents cement from adhering to the metal.
•
Keep cement off threads and out of the high pressure ports on the top plug of the test
cell.
•
Lubricate the threads on the test cell plugs before every test with an anti-seize
lubricant.
•
Thoroughly clean test cell of all cement immediately after each test.
•
Replace the O-rings after every test.
•
Replace the inline water filter element every 3 months under normal use or every
month under severe use with poor water quality.
7 Micron Filter Replacement
Open the rear panel on the back of the instrument. Locate the filter (item 30 on drawing 84-
0007), remove the snap ring and filter housing cap. Remove the filter and replace with new
filter part number C09872. Reassemble the filter housing cap and replace the snap ring.
