Inquiry

1. A timer controls lubrication and interval times.

2. The electronic box has four indicators: ACT (action), ALM (alarm), RUN (lubrication) and INT (interval).

3. Includes a pressure gauge for checking operating pressure.

4. A forced lubrication button (F button) is provided. Do not hold it for more than 3 minutes continuously, to prevent motor overload.

5. Motor thermal protection is provided. At 100°C, the motor temporarily stops for approximately 5 minutes.

6. An optional 60 kgf/cm² pressure switch can detect damage to the lubrication lines.

7. An optional reed-switch oil-level detector can monitor level and send a signal automatically.

8. The controller includes a buzzer. On models fitted with a pressure switch or magnetic reed oil-level sensor, it sounds when abnormal pressure or oil level is detected.

9. Fill the KGN and KGNP-50 reservoirs through the grease nipple to prevent air and foreign matter from entering.

10. KGNP-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.

11. Refer to the diaphragm pressure switch specifications for contact information.

◆ Replacement Procedure

1		Hold the grease cartridge cover firmly and turn it counterclockwise to loosen it.
2		Remove the cover and spring.
3		Turn the empty grease cartridge counterclockwise and remove it.
4		Before installing a new cartridge, squeeze out a small amount of grease to prevent air entering the lubricator.
5		Turn the new cartridge clockwise to secure it to the cover base.

6		Refit the cover and spring.
7		Turn the cover clockwise to secure it to the base and complete cartridge replacement.
