8-1   Daily Inspection
Make certain to carry out daily inspection in accordance with Table 8-1. Lack of inspections is a source of trouble.
- If any problems are found in a daily inspection, follow "9. Troubleshooting" (on P16 and 17) to take ap- propriate actions.  If these actions do not solve the issue, immediately contact the nearest authorized maintenance shop.
8-2  Main Unit Maintenance
- Because the gear unit is filled with long-lasting grease, it can be used for long time without replenishing the grease, but maintenance with disassembly after usage for approximately 20,000 hours or 3 to 5 years will further extend the product lifetime. Contact the nearest authorized maintenance shop regarding maintenance with disassembly. - Oil seals have a lifetime. During long use, natural degradation and frictional wear will reduce effective- ness. Product operating conditions and ambient environment will cause lifetime to widely vary. Given normal operation (uniform load, running 10 hours per day, normal temperature) as a quideline, it is rec- ommended to change them every 1 to 3 years. If the sliding surfaces of oil seals show signs of wear or corrosion, replace them with new ones. The sliding surface of an oil seal is made of carbon steel, so in order to prevent rust forming on it, if there are parts of the oil seal that are exposed to the outside, periodi- cally take steps to prevent rusting by coating the oil seal with rust preventive oil. Contact the nearest authorized maintenance shop regarding oil seal replacements. - If stop and start are frequent, mounting bolts (or nuts) may come loose. Periodically check for looseness as this is a source of miss-alignment, grease leakages, and load unbalance.
8-3  Wheel (Option) Maintenance
- The wheel with urethane tire is consumable. Check and replace by referring to the below (for installing, see P9 and P10).
If any abnormal condition occurs, refer to Table 9-1, 9-2 and promptly take appropriate measures. If these actions do not solve the issue, immediately contact the nearest authorized maintenance shop.
