Note:

In case of no wear-resisting hydraulic pressure listed in the table, it may be substituted by

machine oil or ordinary hydraulic oil of corresponding brand (viscosity), i.e., N46 may be

used in summer and winter, after ordinary machine oil or ordinary hydraulic oil is used, the

service life of hydraulic elements might decrease accordingly.

In summer at a hot region, L-HM68 wear-resisting hydraulic oil shall be used, and in winter

at a bitter cold region, L-HM32 wear-resisting hydraulic oil shall be used.

Precautions in use of oil

1) For the fuel oil and machine oil for engine, different brand of diesel oil and machine oil

shall be selected in winter according to different region and air temperature. Refer to

Table 1.

The diesel oil in the diesel oil box must be supplemented in time, so as to prevent

running out. The diesel oil shall be examined once each month to see whether it is

polluted or not, is there any deposit or not, and the oil filter shall also be cleaned.

The machine oil for diesel engine must be replaced regularly, since the mechanical

impurity in the oil might increase with time, the reason for increase of impurities is:

There is resultant after oxidation and wearing of parts, there is residue after

combustion in cylinder, and foreign dust falls into it. When the content of those

reaches 0.4-0.5, the oil becomes black, and the physical and chemical indexes

worsen. Oil replacement shall be conducted in the hot status.

2) The cleanliness of hydraulic oil shall be examined periodically. The method is: take a

drop of oil from oil tank, drip it into 240-mesh filter paper, if a flaxen loop appears on

the paper, the continued use of the oil is proved to be available; if the outer ring of the

yellow loop on the paper is obvious and its center is black colored, the oil is proved to

have been polluted and need replacing. Instrument can be used for examination if

of 44

possible. At the time of adding new oil, it must pass through oil filter, and it is not

allowable to mix several hydraulic oils for use.

3) At the time of using 719 or 7100 automobile brake fluid, the material of sealing element

in the braking system is oil-resistant acrylonitrile-butadiene rubber, it is strictly

prohibited to use brake fluid, and mixed use of different category of brake fluid is not

allowable.

4) In order to protect gear and save engine fuel, for the main driving in the driving axle

and the wheel reductor, heavy-duty vehicle gear oil shall be selected and used in

reference to Table1.2.

Please be careful:

You should pay more attention to the oil material in use for it has close relation with service

life and performance of mechanical loader, the gear oil shall not be substituted at will, and

that is even more serious for machine oil, hydraulic oil and gear oil for diesel engine

working at high speed under high temperature.

Due to the incessant development of new oil materials, the above oil specification and

brand are not all-inclusive, and the users shall pay attention at the time of use！

3. Precautions for lubrication

1) The oil pan of engine and the trapped fuel amount of hydraulic oil tank are just between

the upper and lower limits of oil scale. The oil surface for driving box, rear axle and

front axle shall be added to the oil orifice (observation orifice).

2) Before filling of oil, the oil orifice or oil cup shall be cleaned.

3) For clearing and replacing oil at the driving box, front axle and rear axle, the old oil

shall be fully discharged at the hot machine status, then light diesel oil or kerosene

(blended with 5% machine oil) shall be added, then start the engine for operation

without load at low speed for 2-3 minutes, discharge the cleaning oil, fill in clean

lubricating oil, meanwhile, the air plug and drain plug etc. shall be cleaned.

4) For new vehicle or 500 hours of working after overhaul, the hydraulic oil shall be

replaced, oil shall generally be replaced once every half a year before and after

running-in. If the oil fluid is not denatured or not discolored, it can be prolonged

appropriately, but that shall not exceed one year. At the time of replacing oil, the oil

tank and fine filter shall be carefully cleaned, the fine filter is mounted at the oil suction

of 44

orifice in the oil tank, the filter element (filter screen) shall be replaced when

necessary. After sedimentation for 48 hours, hydraulic oil passes through the filter

screen at oiling orifice (it is suggested to use silk fabric for filtration), meanwhile, the

pipe joint and other connective part shall be fastened, and the sealing part shall be

replaced when necessary. The filter shall generally be cleaned once every month. If

the filter element is broken or there is much dirt, it shall be replaced.

5) Lubricating grease shall be applied once about every month for the exposed part of

hydraulic cylinder piston rod.

6) After overhaul inspection, repair or replacement of parts, relevant parts shall be

lubricated.

II. Protection and Storage

of 44

For the mechanical loader that needs storage for a relatively long period, it shall be

protected and stored in accordance with the following stipulations:

Clean and maintain in an all-round way, so as to reach the aim of no corrosion, no oil dirt

and no other pollutant, fully discharge the cooling water, and conduct anticorrosion and

protection treatment to the machine.

1. Anti-corrosive method

1) The preservative coating generally includes: non-corrosive paper, alcohol, alcohol

water solution preservative and powdery preservative, etc. The anti-corrosive method

is as follows:

a. Non-corrosive paper: the parts of machine may be packed with non-corrosive

paper, and there shall be enough overlapping amount at the boundary of package.

At the time of packing parts with complicated shape and relatively great weight by

non-corrosive paper, protective layer of plastic film or metal foil product can be

added externally.

b. At the time of anticorrosion to the cavity on the machine that needs enclosing in the

operation process, gas preservative or powdery preservative of alcohol, water

solution stirred with alcohol may be selected and used. After the internal surface of

cavity is treated with preservative, surplus preservative solution shall be removed,

and drying treatment shall be conducted. After the preservative forms crystal, seal

all orifices of the cavity with non-corrosive paper or binder.

2) Applying oil paint

a. For the external surface of machine parts, oil may be coated by means of spraying

or brushing immersion, etc. After full dripping of surplus oil, the oil film shall be

even.

b. For the internal surface of machine parts, oil fluid may be poured in, or it can be

filled into the cavity bore by oil pump, then rotate corresponding movable parts of

the machine, so that the oil film is even, and let the surplus oil drip fully.

c. For the internal surface of hydraulic system whose anticorrosion depends on

hydraulic working oil, hydraulic working oil shall be filled to the full.

d. At the time of antirot treatment to the machine surface with dissolved antirot

coating or paint, it shall be conducted by means of spraying or brushing, etc.

e. When any defect on the antirot layer is detected, the surface at the defect part shall

of 44

be cleared, and then apply the same paint or oil material.

3) At the time of using antirot polymer, the coating shall be guaranteed to be continuous

and even, and there shall be no inclusion.

4) In order to prevent the influence of sunlight on the quality of rubber, a layer of light-

proof compound shall be applied on the surface of rubber part by means of spraying or

brushing, and it can also be wrapped with black neutral wax paper.

5) Besides the above single item of antirot method, other methods or two or many of the

above antirot methods can be used for joint anticorrosion. For whichever method that

is used, the machine and parts shall not be damaged.

6) Remove the antirot matter with the method listed in Table 1

Antirot method

Apply preservative on surface Strip the non-corrosive paper, use dry hot air to

purge clean or alkali solution of soap to flush.

Apply oil or paint onto the surface Use detergent and hot water to clean, or firstly

use organic solvent to wipe clean, and then

flush with detergent and hot water.

Apply antirot polymer onto the surface At the appropriate part, cut off the polymer

membrane and strip it.

Apply light-proof compound onto the

surface, or wrap with black neutral

wax paper

Use detergent to clean the light-proof compound

coating that shall be removed, or strip the light-

proof wax paper.

2. Storage

1) A storage period over two months is long-term storage. The long-term storage is

divided into two categories:

a. Two months to one year

b. Over one year

2) The storage ground for machine can be divided into: outdoor ground, sheltered ground,

closed thermal insulation warehouse, and warehouse with air-conditioning.

a. Before long-term storage of machine, protection treatment shall be conducted to it,

the circumstance of package sealing etc. shall be examined carefully in an all-

round way;

b. The stored machine shall be padded levelly with support, and the distance between

of 44

each wheel and each supporting object shall not be less than 8cm.

c. The orifice on machine, such as adjustment orifice, air inlet, discharge orifice, etc.,

shall be tightly sealed with lid, stopper, waterproof adhesive plaster or other

special-purpose device.

d. Put the operating handle and pedal at the position where no danger would occur

even if the machine operates occasionally.

e. The accumulator on the stored machine shall not be open-circuited, the

concentration of electrolyte and the height of liquid surface shall conform to the

stipulations of manufactory. When the storage of machine exceed one month, the

accumulator shall be detached from the machine, and shall be put to a special-

purpose place for storage.

f. The fuel oil, lubricating oil, hydraulic oil, cooling fluid and water etc. on the stored

machine shall be added or discharged according to the stipulations of manufactory

or relevant managerial department.

g. For the machine stored for long period, the circumstance of its appearance quality,

protective surface and preservative matter shall be examined periodically, and the

interval of examination shall be as follows:

⑴ In the season and region with warm climate, it shall be examined once every six

months;

⑵ In the tropical zone, temperate zone when it is cold or in the coastal region in the

frigid zone, it shall be examined once every three months.
