WARNING
●
Avoid contact with rotating parts such as the shaft while carrying out maintenance or
inspection. Rotating parts can catch body parts and cause injuries.
●
Do not unplug the pressure vent during operation because hot oil may splash and cause burn
injuries.
●
Verify that the drive and driven shafts are completely stopped prior to inspecting gear teeth.
Failure to do so may result in accidents.
●
Do not overload the reducer. Doing so may damage the unit and shorten gear life.
CAUTION
●
Change lubrication according to the instruction manual. Use only the lubrication
recommended. Other kinds of lubrication may damage your equipment.
●
Touching the reducer surface with bare hands may cause burn injuries.
●
Do not lubricate the reducer during or immediately after operation. Doing so may cause burn
injuries.
●
Handle troubles according to the instruction manual. Be sure to stop the operation and do not
resume until the cause of the trouble has been identified.
●
Repair, disassembly and assembly must be carried out by certified engineers.
