The Sokkia total station is a high precision, delicate machine, and should be treated as such bythe operator in the field.
Its replacement cost is significant.
The operator should be careful never to use force when operating the total station.
It is manufactured to high tolerances, and a delicate touch is all that is required to perform all of its functions.
Rough use or weather conditions such as rain and snow can damage it. It should not be used in such weather.
If the machine gets wet in the field, it should be brought inside and wiped dry with a soft cloth.
Putting the total station away in a wet case will cause the machine to pull moisture into thetelescope, and possibly into the keyboard screen itself.
The case should be dried out and left open for twenty-four hours to allow all humidity to escape before locking it shut on the total station.
The operator should never attempt to lubricate the total station with any type of lubrication.
Only authorized dealers should perform this task.
If care is used by all of the operators, the machine should be available for use for a very long time.
