Operation notes:
1. Only trained drivers with a driver’s license can drive;
2. Check the control and alarm devices before driving. If damage or defects are found, they should be operated after repair;
3. The specified load should not be exceeded during transportation. The fork must be inserted under the cargo and the cargo should be evenly placed on the fork. It is not allowed to pick the cargo with a single fork tip;
4. Start, turn, drive, brake and stop smoothly, and slow down when turning on wet or smooth roads;
5. When the load is moving, the cargo should be lowered and the mast tilted back;
6. Drive on slopes carefully. When more than one-tenth of the slope is driving, the uphill slope should be driven forward, the downhill slope should be driven backwards, and the uphill and downhill slopes should not be steered. Loading and unloading operations;
7. Pay attention to pedestrians, obstacles and potholes, and pay attention to the gap above the forklift when driving;
8. People are not allowed to stand on the fork, and people are not allowed on the truck;
9. People are not allowed to stand under or walk under the fork;
10. It is forbidden to manipulate vehicles and attachments from a position other than the driver's seat;
11. Do not carry unfixed or loosely stacked goods, and handle large-size goods carefully;
12. For high-truck forklifts with a lifting height greater than 3 meters, pay attention to the falling of the upper cargo, and take protective measures when necessary; tilt the portal frame as far as possible during work, and tilt it forward and backward within the minimum range;
13. When adding fuel, the driver should not be in the car and stop the engine. When checking the battery or fuel tank liquid level, do not ignite;
14. When leaving the car, lower the fork to the ground and put the gear handle in the neutral position. The engine is turned off and the power is disconnected. The hand brake is pulled well. When parking on the slope, it must also be cushioned wheel.
Forklift maintenance:
To make the forklift work normally and reliably, and to exert the potential of the forklift, there must be regular maintenance measures. Technical maintenance measures are generally:
1. Daily maintenance, after every shift.
2. First-level technical maintenance, after a total of 100 hours of work, a shift system is equivalent to 2 weeks.
3. Second-level technical maintenance, after a total of 500 hours of work, one shift system is equivalent to one quarter
1. Routine maintenance
1. Clean the dirt, soil and dirt on the forklift, the key parts are: fork and gantry slides, generator and starter, battery electrode fork column, water tank, air filter.
2. Check the tightening of each part, the focus is: fork frame support, lifting chain tensioning screws, wheel screws, wheel fixing pins, brakes, steering gear screws.
3. Check the reliability and flexibility of the steering gear.
4. Check the leakage, the main points are: each pipe joint, diesel tank, engine oil tank, brake pump, lifting cylinder, tilting cylinder, water tank, water pump, engine oil pan, torque converter, transmission, drive axle, main deceleration Device, hydraulic steering gear, steering cylinder.
5. Tyre pressure check: If the shortage is insufficient, please add to the specified value to confirm that there is no air leakage. Check whether the tire contact surface and side surface are damaged, and whether the rim is deformed.
6. Brake fluid and water volume check: check whether the brake fluid is within the scale range, and check whether air is mixed into the brake pipeline. When adding brake fluid, prevent dust and water from entering. When adding water to the water tank, use clean tap water. If antifreeze is used, add the same antifreeze. When the water temperature is higher than 70°C, do not open the water tank cover. When opening the cover, place a thin cloth on it and do not use gloves to twist the water tank cover.
7. Engine oil quantity, hydraulic oil, electrolyte inspection: first pull out the oil scale, wipe the ruler head and then insert and then pull out to check whether the oil level is between the two scale lines. The oil level in the working oil tank should be between the two scale marks; too little oil, air will be mixed into the pipeline, too much will overflow from the cover. The electrolyte of the battery should also be between the upper and lower scale lines. If it is insufficient, add distilled water to the top line.
8. Brake pedal, inching pedal, clutch pedal, hand brake check: step on each pedal to check whether there is abnormal slowness or jamming. The force of the hand brake handle should be less than 300N, confirm that the hand brake is safe and reliable.
9. Check the belt, horn, lighting, instrument, etc.: Check whether the belt tightness meets the regulations, there is no adjustment margin or damage or crack, it must be replaced; the horn, lighting, instrument should be normal and effective.
10. Remove the oil filter sediment.
Second, first-class technical maintenance
According to the "daily maintenance" project, and add the following work.
1. Check cylinder pressure or vacuum degree.
2. Check and adjust the valve clearance.
3. Check whether the thermostat works normally.
4. Check whether the multi-directional valve, lifting cylinder, tilting cylinder, steering cylinder and gear pump work normally.
5. Check whether the transmission shifting is normal.
6. Check and adjust the gap between the brake pads of the hand and foot brakes and the brake drum.
7. Replace the oil in the oil pan, check whether the crankcase ventilation connection is intact, and clean the oil filter and diesel filter element.
8. Check whether the generator and the starter motor are firmly installed, and whether the terminals are clean and firm, and check the carbon brush and commutator for wear.
9. Check the tightness of the fan belt.
10. Check whether the wheel is installed firmly, whether the tire pressure meets the requirements, and remove the sundries embedded in the tread.
11. The parts are disassembled due to maintenance work, and the forklift truck road test is required after reassembly.
(1) The braking performance under different degrees should be free from deviation and meandering. On a steep slope, after the hand brake is tightened, it can stop reliably.
(2) Listen for abnormal sound when the engine is running under acceleration, deceleration, heavy load, or no load.
(3) After a road test, check the brakes, transmission, front axle housing and gear pump for overheating.
(4) Whether the lifting speed of the fork frame is normal and whether there is tremor.
12. Check whether the diesel oil inlet filter is clogged and damaged, and clean or replace the filter.
Third and second level technical maintenance
In addition to maintaining each item according to the first-level technical maintenance, and adding the following tasks:
1. Clean the fuel tanks, filter screens and pipelines, and check for corrosion and cracking. After cleaning, do not use fiber yarns and cloths to wipe.
2. Clean the torque converter, gearbox, check parts for wear and replace with new oil.
3. Check the bearing of the drive shaft, and change the direction of the universal joint cross shaft if necessary.
4. Check the tightening condition of each part of the drive axle and whether there is oil leakage, and clear the air holes. Disassemble and inspect the main reducer, differential, and wheel reducer, adjust the axial clearance of the bearing, and add or replace the lubricant.
5. Dismantle, inspect, adjust and lubricate the front and rear wheels, and perform half-shaft transposition
6. Clean the brake and adjust the gap between the brake drum and brake shoe friction plate.
7. Clean the steering gear and check the free rotation of the steering wheel.
8. Disassemble and clean the gear oil pump, pay attention to check the wear of gears, housing and bearings.
9. Disassemble the multi-way valve, check the gap between the valve stem and the valve body, and do not disassemble the safety valve unless necessary.
10. Check the steering knuckle for damage and cracks, the cooperation between the steering axle kingpin and the steering knuckle, and dismantle and inspect the wear of the joints of the crossbar and steering arm.
11. Disassemble the tire, remove the rust and paint the rim, check the inner and outer tires and the cushion belt, change the position and inflate according to the regulations.
12. Check the connection and tightening of the hand brake mechanism, adjust the working stroke of the hand brake lever and foot brake pedal.
13. Check the battery's electro-hydraulic specific gravity. If it does not meet the requirements, it must be removed for charging.
14. Clean the water tank and oil radiator.
15. Check whether the shelf and the frame are deformed, whether the disassembly and cleaning rollers and the attachments are reliable, and if necessary, add welding firmly.
16. Dismantle the lifting cylinder, tilt cylinder and steering cylinder, and replace the worn seals.
17. Check each instrument sensor, fuse and various switches, and adjust if necessary.
Fourth, vehicle lubrication
For a new forklift or a forklift that has stopped working for a long time, for the bearings that should be lubricated, when lubricating, the new oil should be used to squeeze out the old oil and lubricate it for more than two times. The following points:
1. Remove the dirt on the oil cap, oil plug and grease nipple before lubrication to prevent the dirt from falling into the mechanism.
2. When injecting the lubricant with a grease gun, it should be infused until the parts are extruded with lubricant.
3. Seasonal lubricants (motor oil, etc.) should be replaced in summer or winter.
