The daily maintenance of forklift parts is mainly based on cleaning, lubricating and checking the usage status of the parts, and the forklift driver is responsible. The forklift driver should strictly follow the daily maintenance and technical requirements, and carry out it once per shift. If the forklift is found to be abnormal, it should be handled in time. Daily maintenance includes daily inspection before use, inspection during work and maintenance after returning to warehouse. The specific items are as follows:

A. Daily check before use:

1. Check whether the fuel, lubricating oil, hydraulic oil and coolant are adequately added;

2. Check whether there is any leakage of oil and water in the whole vehicle;

3. Check the working conditions of various instruments, signals, lighting, switches and buttons and other ancillary equipment (check whether the horn and each lamp can work normally, whether the turn signal lamp flashes normally, whether the lamp is damaged and whether it is covered).

4. Check the technical conditions and tightening conditions of steering, braking, tires and traction devices.

5. Check the technical condition and tightness of the lifting mechanism, tilting mechanism, fork frame and hydraulic transmission system.

6. Check items before starting the engine: Whether there is oil or water leakage (patrol the body for a week to check for traces of oil or water leakage, especially check the joints of the hydraulic pipeline, oil cylinders, pumps, and control valves).

7. Check items after the engine is started: A. Abnormal sound and vibration (especially check whether the engine and the liquid oil pump have abnormal noise and vibration); B. Engine exhaust color (exhaust color is colorless or light blue is normal ).

8. Engine oil quantity: check with an oil gauge, add enough if it is insufficient. If the engine oil is dirty or discolored severely, the oil should be replaced.

9. Check whether the tools and accessories are complete.

B. Inspection items of various forklift parts at work:

1. Whether the tire pressure meets the specified pressure, the tire’s wear and damage, and the wheel hub’s deformation and damage. In addition, check whether there is any foreign matter caught in the tire, and tighten the wheel nut according to the specified torque.

2. Cooling water volume (remove the radiator cover, check if the water is sufficient, fill it up if insufficient).

3. The elasticity of the V-belt: press the center of the belt with your hand to check whether its deflection meets the standard. If the belt is scratched or cracked, replace it with a new belt.

4. Oil quantity in working oil tank: check with oil meter and add enough if insufficient.

5. Pedal action: check whether the pedal is too heavy, whether it can bounce back, and the micro-motion pedal and the brake pedal are linked.

6. Steering wheel: The normal clearance of the steering wheel on the circumference is 30-60mm. Check whether the steering wheel is deflected, whether it cannot be controlled when running in a straight line, and whether the steering is too heavy. In addition, check whether it moves up and down.

7. Fuel capacity of the fuel tank: Turn the start switch to the “power” position and look at the position of the fuel gauge pointer on the instrument panel. If the amount of oil is insufficient, fill it up. When refueling, pay attention to keeping the refueling port and the oil clean.

8. Instrument: Check whether the oil pressure warning light and charging warning light are off, and whether the pointers of the engine water temperature gauge and theoil temperature gauge are in the green zone.

9. Chain tension state: Raise the fork 10-15mm, press the center of the chain with your fingers, and see if the deflection of the left and right chains are the same.

10. Pedal: Check whether the braking effect is sufficient, or there is only unilateral braking. Whether the vehicle can move forward slowly when stepping on the jog pedal. Whether to brake when stepping on further.

C. Maintenance items after returning to the warehouse:

1. Clean the outside of the forklift
2. Add fuel, check lubricating oil, coolant, hydraulic oil, etc.
3. Check whether the V-belt is in good condition and tightness.
4. Check the tire pressure.
5. Check the tightness of the forklift frame and the fastening bolts of the lifting chain.

6. Check the fittings of the lifting hydraulic cylinder, tilt hydraulic cylinder, steering hydraulic cylinder and all pipe joints for leakage.
7. Eliminate faults found during work.
8. Check and arrange the tools and accessories on the vehicle.

9. The following items should be added every 40-50h of work:
1) Clean the filters of each forklift;
2) Clean the outside of the forklift battery, check the height of the electrolyte level and the cleanliness and tightening of the terminals and connecting wires;

3) For gasoline-powered forklifts, check the loose bolts on the outside;
4) Check and tighten the loose bolts on the outside of the entire vehicle assembly;
5) For coolant pump bearings, universal joint king pins, horizontal and straight tie rod ball pins, tilt hydraulic cylinder horizontal pins, three-link center pins, fork frames, rollers, etc.
Lubricate the parts;
6) Lubricate and adjust the lifting chain.
