The daily maintenance of forklift should make the forklift work normally and reliably, give full play to the potential capacity of forklift, there should be regular maintenance measures. Technical maintenance measures, generally:

1. Daily maintenance: after each shift.

2. First-level technical maintenance: after 100 hours of work, one shift is equivalent to 2 weeks.

3. Secondary technical maintenance: after a total of 500 hours of work, one shift is equivalent to one quarter.

I. daily maintenance:

1. Clean dirt, soil and dirt on the forklift, the key parts are: cargo fork rack and door rack slide, generator and starter, battery electrode fork column, water tank and air filter.

2, check the fastening situation of each part, the key is: fork support, lifting chain tension screw, wheel screws, wheel fixing pin, brake, steering screw.

3. Check the reliability and flexibility of the foot brake and steering gear.

4, check the leakage situation, the key is: each pipe joint, diesel tank, oil tank, brake pump, lift oil cylinder, inclined oil cylinder, water tank, water pump, engine oil sump, torque converter, transmission, drive axle, main reducer, hydraulic steering gear, steering cylinder. 5. Remove the oil filter sediment.

Ii. First-level technical maintenance: according to the daily maintenance project, add the following work:

1. Check the cylinder pressure or vacuum.

2. Check and adjust valve clearance.

3. Check whether the thermostat works normally.

4. Check whether the multi-way reversing valve, lifting oil cylinder, tilting oil cylinder, steering oil cylinder and gear pump work normally.

5. Check whether the transmission shift is normal.

6. Check and adjust the gap between brake disc and brake drum of hand brake and foot brake.

7. Replace the oil in the oil sump, check whether the crankcase ventilation connection is intact, and clean the oil filter and diesel filter element.

8. Check whether the installation of generator and starting motor is firm, and whether the wiring head is clean and firm, and check whether the carbon brush and commutator are worn.

9. Check the tightness of the fan belt.

10. Check whether the wheel installation is firm, whether the tire pressure meets the requirements, and clear the debris embedded in the tread.

11. Parts are dismantled due to maintenance work, and road test of forklift shall be conducted after reassembly.

(1) the braking performance under different degrees shall be free from off-tracking or snaking. On the steep slope, after the hand brake is tight, it can stop reliably. (2) listen to the normal sound when the engine is running under acceleration, deceleration, heavy load or no load.

(2) after a road test, check whether the brake, transmission, front axle housing, gear pump overheating.

(3) whether the lifting speed of cargo fork rack is normal and whether there is trembling.

12. Check whether the filter screen at the oil inlet of diesel tank is blocked or damaged, and clean or replace the filter screen.

3, secondary technical maintenance: in addition to the technical maintenance according to the first level of each project, and add the following work:

1. Clean each tank, filter screen and pipeline, and check whether there is corrosion or cracking. After cleaning, do not wipe with yarn and cloth with fiber.

2. Clean torque converter and gearbox, check the wear of parts and replace with new oil.

3, check the transmission shaft bearing, as necessary to replace the direction of the universal joint cross shaft.

4. Check the fastening condition of each part of the drive axle and whether there is oil leakage, and dredge the air holes. Check main reducer, differential, wheel side reducer, adjust bearing axial clearance, add or replace lubricating oil.

5. Inspect, adjust and lubricate the front and rear wheel hubs, and conduct semi-axle transposition.

6. Clean the brake and adjust the gap between brake drum and brake shoe friction disc
