10. Repairs and maintenance
One of the advantages of the SANDEX unit is that it is easy to handle. However, improper use can affect
the life and performance of your SANDEX unit. The following items explain basic repair and maintenance
procedures.
(1) Periodically, check for backlash in the input and / or output systems. Backlash that goes
unnoticed may develop even further over the years. Check for red rust as this indicates the
occurrence of fretting corrosion. Re-tighten any locations where red rust appears.
(2) Running your SANDEX unit without oil will cause internal damages. Note, overfilling can
be the cause of abnormal temperature rises and oil leaks.
(3) Replace lubricating oils every 3000 operating hours. Note, for operating hours less than
this, replace the oil once every year.
(4) Supply lubricating grease every 2000 to 4000 operating hours. For 23AD,
supply a shot of 20 to 30 g. For smaller models, supply approximately 5 to 10 g.
(5) The Sigma II driver is supplied with a Toshiba, ER3 V, 3.6V, 1000mAH battery.
The driver is also equipped with a battery light. This light should be checked
as a general maintenance item, and when illuminated the battery will need
replaced.
