The new forklift needs a run-in period to be used within the specified operating time. The operational characteristics of the internal combustion forklift during the running-in period are:

  • The machined surface of the parts is rough.
  • The lubrication efficiency is poor.
  • The wear is intensified.
  • The fasteners are easy to loosen.

Therefore, it must be used and maintained according to the provisions of the run-in period of the internal combustion forklift.

The maintenance period of the internal combustion forklift during the running-in period is 50 hours from the beginning of use. The specific contents are as follows:

1、 The main content of early maintenance is to check the forklift and make preparations before use.

1. Clean the whole forklift;

2. Check and tighten the external bolts, nuts, pipeline joints, clamps and safety locking devices of all assemblies of the whole forklift;

3. Check the oil and water of the whole forklift for leakage;

4. Check the liquid level of engine oil, gear oil, hydraulic oil and coolant;

5. Lubricate all lubrication points of the whole forklift;

6. Check the tire pressure and hub bearing tightness of the new forklift;

7. Check the toe-in of the steering wheel, steering angle and the connection of all parts of the steering system of the new forklift;

8. Check and adjust the free travel of forklift clutch and brake pedal and the travel of parking brake lever, and check the braking efficiency of the braking device;

9. Check and adjust the tightness of the V-belt;

10. Check the electrolyte level, density and load voltage of forklift battery;

11. Check the operation of instruments, lighting, signals, switch buttons and onboard auxiliary equipment;

12. Check the stroke of the control lever of the distribution valve of the hydraulic system and the stroke of each working hydraulic cylinder;

13. Check and adjust the tightness of the lifting chain;

14. Check the operation of gantry and fork;

2、 The medium-term maintenance is generally carried out after 25 hours of operation.

1. Check and tighten the bolts and nuts of forklift engine cylinder head and intake and exhaust manifold;

2. Check and adjust valve clearance;

3. Lubricate all lubrication points of the whole forklift;

4. Replace the lubricating oil of forklift engine;

5. Check the sealing and leakage of lifting hydraulic cylinder, tilt hydraulic cylinder, steering hydraulic cylinder and distribution valve.

3、 The later maintenance is generally carried out 50 hours after the operation of the new forklift.

1. Clean the whole forklift;

2. Remove the speed limiting device of gasoline/diesel engine;

3. Clean the forklift engine lubrication system, replace the forklift engine oil and oil filter element, and clean all ventilation devices of the whole forklift;

4. Clean the transmission, torque converter, drive axle, steering system, working device and hydraulic system, and replace the lubricating oil and hydraulic oil. Clean the filter screen of each oil tank;

5. Clean the air filter of each forklift;

6. Clean the fuel filter, gasoline pump sedimentation cup and filter screen, and discharge the sediment in the fuel tank;

7. Check the tightness and lubrication of forklift hub bearing;

8. Check and tighten the bolts, nuts and safety locking devices outside all assemblies of the whole vehicle;

9. Check the braking efficiency;

10. Check and adjust the tightness of the V-belt;

11. Check the electrolyte level, density and load voltage of forklift battery;

12. Check the working condition of working forklift device;

13. Lubricate all lubrication points of the whole forklift.

4、 After the after-sales maintenance or long-term shutdown of a new forklift, the forklift maintenance plan shall be strictly implemented. The bearings shall be lubricated within two weeks of the start of use. When adding oil for lubrication, all the old oil shall be squeezed out with new oil and lubricated more than twice. At the same time, pay attention to the following points:

1. Before lubrication, the dirt on the forklift oil cover, oil plug and nozzle shall be removed to prevent the dirt from falling into the mechanism.

2. When the lubricant is injected with the grease gun special for forklift maintenance, it shall be injected until the parts of each component combine to extrude the oil.

3. Seasonal lubricants (oil, etc.) should be replaced in summer or winter.
