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 during operation to ensure proper, uniform circulation.
• Add grease slowly.
• Do not add more grease than the amount shown in
Table 17
and

Adding too much grease may cause the grease
temperature to rise, or grease to leak into the motor.
Grease Replacement for Grease-Lubricated and Maintenance-Free Grease Models
• The unit may be safely operated for an extended time because it is sealed with maintenance-free grease. However, Sumitomo
recommends overhauling every 20,000 hours or 3-5 years of operation to ensure long service life
• Always consult our specialized factory for overhaul of gearmotors and reducers. Experience is necessary for overhaul.
