MAINTENANCE AND CARE
Introduction

This manual introduces the B, C, L, Z series engine use and precautions, engine maintenance. Onlystrict compliance with the use and maintenance specifications, it can ensure the normal use of the engine.Please read this manual carefully before using the engine.Use fuel oil, lubricating oil and coolant that meetthe requirements of the specification in accordance with the technical specifications.When replacementparts are required, it is recommended that Cummins genuine accessories must be used.

 

During operation, the following engine conditions should be paid close attention to.If any item appearssuddenly, it is likely to be a sign of trouble, please check and repair it in time

  • Poor engine start or stop
  • Underpower
  • Abnormal vibration
  • High oil consumption
  • Abnormal noise
  • High fuel consumption
  • Heavy exhaust smoke
  • Fuel, oil or water leakage
  • Sudden change of working pressure and temperature
Add coolant correctly

The coolant should not be added too quickly, otherwise the air in the engine water jacket is not easyto discharge, resulting in the engine running temperature is too high.

After the coolant is full filled, shut down for inspection after thermal engine, and refilluntil the coolantis full filled.

If the engine is equipped with an intercooler, the air release valve on the water cooler must be openedduring refueling.

Remind

Notes to users that the coolant must beadded as required, otherwise the enginewill be damaged.

 

Warning

The engine cooling system must be filledwith long-term organic coolant.Ethylene glycol or propylene glycol.

 

Reminder

Replacement cycle of rust-proof antifreezing solution is two years.

In winter, must check the concentration of rust-proof antifreezing solution.

The cooling system of the used engine should be cleaned before using rust-proof antifreezing solution.

It is strictly prohibited to use water instead of rust-proof antifreezing solution.
