17-1 Base Unit Grease Replenishment
- All base unit bearings are grease lubricated. Units are shipped greased using the greases in Table 17-2, so they can be used as is.
- Make certain to perform maintenance. Neglecting maintenance is a source of problems.

Note : 1. The symbol □ in frame size can be “0” or “5”. For double reduction and triple reduction types, DA, TA, etc. will be appended to the
frame size.
2. Replenishment quantities are the same for double and triple reduction types.
(4) Replenishment Procedure
Using a grease gun, replenish through grease fittings [2] and [8] (see P95, for C3VM, use [6]). See Table 17-3 for guidelines on quantity.
-If the product has not been operated for one year or longer, make certain to replenish grease before resuming operation.
-Grease while the machine is running to improve grease distribution.
-Replenish grease slowly.
-Contact the nearest authorized service station concerning a complete grease change.
17-2 Main Unit Maintenance
Oil seals have lifetimes. During long use, natural degradation and frictional wear will reduce effectiveness. Reducer 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 guideline it is recommended to change them every 1 to 3 years. If the sliding surfaces of oil seals or
V-rings show signs of wear or corrosion, replace them with new ones. Because sliding surfaces for oil seals are made of carbon steel,
take on-going rust prevention measures regularly not to spread rust on them by applying rustproof oil and so on, if there are exposed
surfaces of steel.
