 Forklift maintenance:
   To make reliable, forklift working properly play a the forklift potential ability to have regular

maintenance measures. Technical maintenance measures, generally:
&n bsp;    1, the routine maintenance work in each class.
     2, a technical maintenance after 100 hours of accumulated work, a group of working the equivalent of two

weeks.
     3, two technical maintenance, after 500 hours of accumulated work, a group of working the equivalent of a

quarter.
  First, routine maintenance
    A cleaning forklift dirt, mud and dirt Aye, key positions are: fork frame and slide of the door frame,

generator and starter, battery electrodes fork column, water tanks, air filter.
    2, check the various parts of the fastening, the focus is: fork supports, lifting chain tensioner screw,

wheel screw, wheel pins, brakes, steering screw.
    3, check the steering reliability and flexibility.
    4, check the leakage, the focus is: all fittings, diesel tank, sump, pump the brake, lift cylinders, tilt

cylinders, tanks, pumps, engine oil pan, torque converter, transmission, forklift fork attachments
drive axle, The main gear box,

hydraulic steering, steering cylinder.
    5, the tire pressure checks: less than should be added to the specified value, make sure that does not

leak. Check the tire ground and the side without damage, the rim is deformed.
    6, brake fluid, water check: Check the brake fluid in the scale range, and check if mixed with air in the

brake lines. Add brake fluid to prevent dust,forklift lifting attachments
mixed with water. Add water to the tank, the use of clean tap

water, used antifreeze, should bear the same antifreeze. When the water temperature is above 70 ℃, do not

open the radiator cap, open the lid, the pad is a thin cloth, do not wear gloves tighten the tank cap.
    7, the amount of engine oil, hydraulic fluids, electrolyte check: First pull out the Dipstick, inserted

after the wipe-foot head and then pull out the check the oil level is between two tick marks. Working inside

the tank oil level should be between the two tick marks; oil too little i n the pipeline into the air, too much

will overflow from the cover. Battery electrolyte is also in between the lines of the upper and lower scale,

and lack of will have to add distilled water to reach the peak line.
   8, the brake pedal, micro pedal, clutch pedal, hand brake check: depresses each pedal, check for abnormal

slow or jamming. The hand brake lever of the force should be less than 300N, to confirm the safety and

reliability of the hand brake.
   9, belts, horn, lights, meters, etc. check: Check the belt tightness is required, adjust the margin or

broken crack, to be replaced; speakers, lighting, instrument should be normal.
   10, let go the oil filter sediment.
  Second, a technical maintenance
    In accordance with the \"routine mai ntenance\" project, and add the following work.
    1, check the cylinder pressure or vacuum
    2, Check and adjust valve clearance.
    3, check the thermostat is working properly.
    4, check multiple directional control valves, lift cylinder, tilt cylinder, steering cylinder and the gear

pump is working properly.
    5, check the transmission shift work is normal.
    6, inspection and adjustment of hand, foot brake, brake pad and brake drum clearance.
    7, the replacement of the oil sump, check the crankcase ventilation taken over is in good condition, clean

oil filter and diesel filter elements.
    8, check the generator and starter motor installation is firm, clean and solid wiring connections, check

the carbon brushes and commutator wear.
    9, check the fan belt tight or too loose.
    10, check the wheels are fitted with solid tire pressure meets the requirement, and clear the debris

embedded in the tread.
    11, due to maintenance work and dismantled parts, reassembled forklift road test.
     (1) the braking performance under varying degrees, there should be no deviation, hunting. Tighten the

hand brake on steep slopes, reliable parking.
     (2) listen to the engine running in case of acceleration, deceleration, overloaded or no load, there is

no unusual noise.
     (3) road test for a period of mileage, you should check the brakes, transmission, front axle, the gear

pump at whether the overheating.
     (4) Fork aircraft vertical speed is normal, with or without shaking.
    12, check the diesel tank of fuel import filter whether to plug damage, and clean or replace the filter.
  Third, the two technical maintenance
    In addition to a technical maintenance of each project, and add the following:
    A cleaning of each tank, filters and piping, and check for corrosion, and chipped the situation may not be

used after cleaning with a fiber yarn, cloth, wipe.
    Parts, cleaning the torque converter, transmission, check the wear and replaced with new oil.
    3, check the drive shaft bearing, as the need to swap the axis of universal joint cross.
    4, check the drive axle ministries fastening and without leakage, and clear the pores. Dismantling the

main gear box, differential, wheel reducer, adjust the bearing axial clearance, add, or replace the lubricant.
    5, dismantling, adjustment and lubrication of front and rear wheel hub, axle conversion.
    6, cleaning brakes, adjust the clearance between the brake drum and brake shoe friction plate.
    7, the steering of cleaning, check the steering wheel free rotation.
    8, dismantling and cleaning gear pumps, pay attention to check the gears, shell and bearing wear.
    9, the demolition of multi-way valve, check valve stem and valve clearance, if not necessary, do not open

the safety valve.
    10, check to knuckle whether damage and cracks, the steering axle kingpin and steering knuckle with the

dismantling the vertical and horizontal rod and steering arm joints wear.
    11, demolition of tire on the rim rust paint, check the tires and tubes and flaps, transposition

accordance with the provisions inflatable.
    12, check the hand brake connection fastening of the parts, adjust the hand brake lever and foot brake

pedal travel.
    13 Check the battery electro-hydraulic proportion, such as with the requirements do not match, you must

remove the charge.
    14, cleaning the tank and oil cooler.
    15, check the shelves, whether the frame deformation, removable and washable rollers, fixed the

reliability of the annexes, if necessary, restocking of the weld.
    16 dismantling the lifting cylinder, tilt cylinder and the steering cylinder and replacement of worn

seals.
    17, check the instrument sensors, fuses, and a variety of switches, if necessary, adjust.
  Fourth, the entire vehicle lubrication
    Forklifts, new forklift or long-term stop working after two weeks to start using t he lubrication of the

bearing lubrication, should take advantage of new oil extrusion Chen oil and lubrication for more than two,

should also be noted the following points:
    1, lubrication should be removed oil cap, oil drain plug and the nozzle above the dirt to avoid dirt

falling into the house.
    The injection pressure grease gun lubricant injection pressure to various parts of the parts combined with

the extrusion lubricant date.
    3, in the summer or winter seasonal lubricant (oil, etc.) should be replaced.
