3. Daily Inspection and Maintenance
13-1 Torque Limiter, Daily Check
Open the switch box and check every time that oil is replenished or changed.
(1) Limit Switch
- Use a tester to see if the limit switch activates normally.
- If it is possible to run the device, force the limit switch to activate while the machine is running to determine whether the torque
limiter works properly.
(2) Dog
- Check to determine whether the nut that secures the dog is loose.
- If it is possible to run the device, conrm that, on startup, the dog moves from its stopped condition.
(3) Oil leakage
- Check to determine whether oil has leaked into the switch box.
- If oil leaks in, the limit switch may not activate, preventing the torque limiter from working.
- Do not move the position of the limit switch because moving it will change the preset torque value. This will prevent the torque
limiter from working properly.
- A load test is performed and preset torque is adjusted when the device is shipped from the factory.
If the customer disassembles and reassembles the device, the preset torque could change, causing the torque limiter to stop
working properly. This is a source of damage to the device. Therefore, if disassembly or reassembly is required, contact the nearest
accredited service station.
13-2 Lubricating Vertical Type, Frame Sizes 6130, 6135, 6140, 6145
(1) Lubrication and Maintenance
Vertical CYCLO Drives with Torque Limiter, frame sizes 6130, 6135, 6140, 6145 are grease lubricated.
(For lubrication for other than the vertical type, frame sizes 6130, 6135, 6140, 6145, see P36 – 45.)
Table 13-1 Grease Replenishment Intervals
Operation Time Replenishment Interval Remarks
Less than 10hours a day Once every 3 – 6 months In the case of severe operating conditions, shorten the replenishment period.
Maintenance with disassembly after approximately 20,000hours or three to
ve years will further increase lifetime.
10 – 24hours a day Once every 500 – 1,000hours

(2) Procedures for Filling and Discharging
[1] Remove the grease discharge plug from the casing.
[2] Use a grease gun to replenish through the grease ttings for the internal cover and the motor ange bracket, using the quantities of
grease shown in Table 13-3 as guidelines.
[3] Replace the grease discharge plug.
- Grease while the machine is running to improve grease distribution.
- In addition to being used for discharging grease, the grease discharge plug also functions as a pressure vent when replenishing
grease. Make certain to remove when replenishing.
- Replenish grease slowly.
- Replenishing more than the quantity shown in Table13-3 may cause agitation heat, which raises the temperature, and may cause
grease to leak into the motor unit.
