3.2
Lubricating the Unit
Make sure the breather plug is clean and open to vent heat and pressure. Poor
ventilation may cause overheating and result in damage to oil seals and other
equipment.
Fill the speed reducer to the proper level without overfilling. Too much or too
little lubricant will cause overheating and result in damage to seals, bearings,
and gears.
Lubricate the unit properly to help protect it from wear and rust. Read the
following instructions carefully.
3.2.1
MOTOR BEARINGS are typically lubricated for life by the manufacturer.
Some motors require periodic lubrication. Refer to the motor manufacturer’s
information for specific instructions.
3.2.2
LUBRICATE THE REDUCER according to the manufacturer’s instructions.
a
CHECK OIL LEVEL before every operation and every 10 hours during
operation. Remove the level plug and make sure oil is even with the plug
hole.
b
FILL THE REDUCER according to the manufacturer's instructions. Fill the
reducer until oil reaches the level plug.
Do not mix different lubricants.
c
CHANGE REDUCER LUBRICANT at least every 2 years, or whenever it is
dirty or contaminated.
Important!
• Do not leave plug holes in the
reducer open. Open plug holes
will allow dirt and moisture to
contaminate the lubrication.
• Make sure lubricant has a
temperature rating appropriate for
the ambient temperatures of the
operation.
• Replace the motor bearings if the
motor is disassembled for any
reason.
