5 Maintenance
5.1 Daily
Always check that the platens are clean before commencing the test.
Remove the lower platen and distance pieces and clean thoroughly.
Brush away all concrete debris from the area around the hydraulic ram. In the case
of 2000 kN and 3000 kN BS machines, raising the hydraulic ram will assist in the
removal of this debris etc. from between the folds of the gaiter.
Check for signs of leaks in the hydraulic system.
5.2 Occasionally
Inspect gaiters for damage.
Check the oil level in the oil reservoir.
Inspect the platen for wear.
Check the oil in the reservoir for signs of contamination and replace if necessary.
Due to the design of the seal, a small amount of oil may ‘seep’ out of the ram. This is
not a problem and should be wiped away as necessary.
5.3 Verification
It is normal National Standard requirements to request the verification of load
measuring systems at least once each year or more frequently according to the work
undertaken.
A verification should be undertaken after each occasion when any adjustment to the
compression machine may have affected the load measuring system.
The verification of the load measuring system should be undertaken by qualified
engineers using approved equipment.
Note:
always use a load spreader of approximately 150 mm diameter or more when
calibrating machines to 3000 kN.

Service and Spares
It is recommended that either the ELE Service Department or an authorised
distributor be contacted for details of available spare parts or servicing requirements.

Rectangular Platen Handling Assemblies
7.1 Introduction
Unique platen handling systems enabling the upper platen to be quickly moved to
provide access to, and use of the ball seating. Particularly useful where cube testing
to BS 1881 is specified, the facility does not affect the stability requirements of the
ball seating.
All BS Compression Machines of 2000 and 3000 kN capacity can be supplied fitted
with the above assemblies.
