Grease Replenishment and Draining Procedure
Procedureforaddinggreasetogrease-lubricationmodels(excludingmaintenance-freemodels)
1. Remove the grease discharge plug from the outside cover.
2. Add grease with a grease gun from the grease nipple in the inside cover section or motor connection cover.
3. Insert the grease discharge plug.
Add grease while manually rotating the input shaft to ensure proper, uniform circulation.
Add grease slowly , to prevent internal pressure and possible seal damage.
Do not add more grease than the amount shown in Table 28 and 29. Adding too much grease may cause the grease temperature
to rise, or force the grease to leak into the motor.
Always consult factory and warehouses for overhaul of gearmotors and reducers. Familiarity with Cyclo® products is necessary for proper
overhaul.
