Technical Data  Reducers  Worm Gear Reducers  Handling

This section contains general information regarding the handling of the EWJ/EWJM(R)/EW/EWM(R), and SWJ/SWJM(R)/SW/SWM(R), and TD Series.

For more information, see the instruction manual provided with the product.

6. Operation

・The reducer is filled with lubrication oil and plugged before shipment. Replace the plug with the supplied pressure vent before use.
(Note . Oil may leak from the oil seal due to high internal pressure when not replaced. )
There is no need to change the pressure vent on all EWJ/EWJM(R) and SWJ/SWJM(R) models. Please use the product in the condition in which it was received.

6-1. Double checking before operation

  • ・Upon completing the installation, check the following prior to operation:
    • (1)The reducer is filled with the correct amount of lubrication oil. (The amount of lubrication oil is correct if it can be seen in the oil gauge. )
    • (2)The pressure vent is installed. (If the reducer mounting direction is a special design and comes with a grease nipple, install it as well. )
    • (3)The reducer is connected properly to the driven machine.
    • (4)All mounting bolts are fully tightened.
    • (5)Confirm that the direction of rotation is correct.
  • ・For reducers equipped with a motor, also check the following items
  • ・Confirm that the appropriate breaker and overcurrent relay are used.
  • ・Confirm that the wiring is correct.
  • ・The motor is properly grounded.
  • ・Make sure the equipment incorporates failsafe measures to prevent accidents from occurring during operation of the reducer, or in the event the reducer stops working properly.

6-2. Trial operation

・No trial run is made prior to shipment. For best use, operate the reducer for roughly one day under 1/2 to 1/3 load.

6-3. Load

・Applying the load than its rated capacity will cause shorter life and damage. Loads must be within its rated capacity.

6-4. Inspection after starting

  • ・After starting operation, inspect the following items.
    • (1)Confirm that there is no abnormal vibration or noise.
    • (2)Confirm that there is no shock.
    • (3)The temperature is not unusually high.
  • ・The reducer may generate heat during the first two or three days of operation. This is expected and is not a problem. However, if the housing temperature exceeds 100°C, it could indicate an undersized reducer, low oil level, or improper installation. Do not touch the reducer with your bare hands to prevent from burn injuries.
