Instruction Manual

4. Maintenance

If during the guarantee period, there should be any repairs they must be
performed only by Struers or by authorized Struers' dealers.
Also after expiration of the period of guarantee it is recommended to let
repairs be made by Struers or Struers' dealers or other competent, skilled
personnel.

4.1. Polishing Unit

Residuals of the electrolyte used previously may spoil the following
polishing. Therefore it pays to rinse the polishing cell and pump thoroughly
before filling in a new electrolyte. This may be done as follows:
The electrolyte tank is filled with water and this is pumped through the
system in the usual way. After this rinsing the pump and polishing cell
should be allowed to drip off, in order that the electrolyte is not diluted with
water. If copper or copper alloys have been thinned, some copper may have
deposited on the cathodes. This may be removed with a few drops of nitric
acid before the rinsing.
Tenupol should not be left filled with electrolyte for an unnecessarily long
time, as the submerged parts may be attacked.
Especially A-8 will shorten the life of the metal parts. Never turn the
polishing unit upside down, especially not when there is electrolyte in the
pump, as this may trickle from the pump up to the motor and cause the axle
to stick. Take care that the motor housing does not come in contact with the
electrolyte. The polishing unit may be cleaned on the outside with a cloth
moistened with water. The polishing unit can be flushed with a soft water
spray.

4.2. Control Unit

Avoid spilling electrolyte on the cabinet or front plate of control unit. Clean
the front plate with a damp cloth after use.
