Caution
Improper fat-feeding operations may cause a sharp increase in the pressure
in the reducer or gearbox, damaging internal parts such as the sealing ring,
resulting in oil leakage or poor operation.
The following precautions must be observed:
1.
Be sure to remove the sealing screw on the grease outlet before
fatting.
2.
Use a hand pump to slowly feed the fat.
3.
Be sure to use the specified grease.
4.
After the grease supply, install the sealing screw after releasing the
internal pressure as shown in Table 13-3..
5.
Thoroughly remove grease from floor and operating machine to
avoid slipping.
