1. Operating and pause times are controlled by a PLC. The standard pneumatic pressure-relief version requires an air supply of 4.5–8 kgf/cm²; an electric pressure-relief version is also available and does not require an air supply.
2. Use with a CFB volumetric grease distributor for metered delivery.
3. Includes a pressure gauge for checking operating pressure.
4. A forced lubrication button is provided. Do not hold it continuously for more than 3 minutes, to prevent motor overload.
5. Both single-phase 110V and 220V models include motor thermal protection. At 100°C, the motor stops temporarily for approximately 5 minutes.
6. An optional 60 kgf/cm² pressure switch detects damage to the lubrication lines.
7. An optional reed-switch oil-level detector can monitor level and send a signal automatically.
8. Fill the KGB reservoir through the grease nipple to prevent air and foreign matter from entering.
9. KGBP-07 must be used with a 700 cc bellows-type grease cartridge. Replace the empty cartridge without time-consuming refilling. Cartridges are sold separately; refer to the bellows-type grease cartridge ordering codes.
10. Refer to the diaphragm pressure switch specifications for contact information.
