pressure, which is normal and do not try to lower it. Speed down or stop to cool the tire down. 

Please note: if the vehicle continues to run at a high speed, overheat of tires will likely to result 

in their explosion. 

z  When adjusting the pressure, keep away from the tire as far as possible and must stand at back 

of the tread. 

z  Combustible gas is forbidden to inflate. Dry nitrogen is recommended. Nitrogen can decrease 

potential explosion hazard, because it does not support combustion and can prevent rubber from 

oxidation or deterioration and tire rim from erosion. 

z  In order to avoid over-inflation, proper tools for nitrogen inflation and related training on use of 

such tools are necessary. 

z  Check of tires and rims shall be done every day. It is prohibited to operation under low pressure. 

Check for presence on the tires such phenomenon as cracks or blisters. 

z  Checking whether any connecting bolt or nut of tire rim is missing and whether the twisting 

moment of connecting nut of the rim complies with the value recommended by manufacturer. 

z  When checking tire, do not enter into places in front of or at back of the roll of tire and shall 

stand at the side of the tire. If a tire needs to be removed or disassembled, other tires must be 

fixed in place by wedges. 

z  When welding operation is conducted near a tire, must be careful because an explosion of the 

tire is possible to occur. 

z  Since repair of a tire or a rim is very dangerous, only trained professionals can undertake the 

repair, using specialized tools and following correct procedures. 

z  When replacing a tire, the specification of new tire shall be that as specified so as to ensure the 

sizes and tread patterns of all tires are uniform. 

Whenever it is avoidable, do not enter into the range showed in the drawing below.

8.14 Notices on Tire Storage 

z  As a basic rule, tires shall be stored in a warehouse where any one can not enter into without 

permission. If storing tires outdoors, set up fences around the tires and hang a label of “No 

entrance”. 

z  Since moisture can quicken oxidation of rubber and dirt or oil can corrode tires, the storage 

place of tires shall be dry and clean. When storing tires, light, heat and air circulation shall be 

avoided and the tires shall be covered by canvas, plastic clothing or other duster. Incorrect 

storage practice will adversely affect quality and service life of tires. 

z  The tires shall be placed on level ground vertically and be chocked firmly by wedge blocks so 

that unapproved touch will not make them fall down. If they are placed horizontally, the tires 

will be pressed flattened and their quality deteriorated. At least once of rotation (of 90°) shall be 

made for each tire. 

z 

When tires are falling down, get away quickly. Tires of construction machinery are very heavy, 

severe injuries may be caused if attempting to hold it. 

 

 

8.15 Waste 

    In order to prevent pollution, especially at the living places of human and animals, the following 

procedures must be followed. 

z  No pouring the waste oil into the sewer and river etc. 

z  Place the oil discharged from the machine in a container, not directly discharge it to the 

ground.  

z  In processing of harmful substances such as lubricant, coolant, solvent, filter, accumulator and 

others, the local laws and regulation shall be observed. 

z  The waste tyres replaced shall be placed at an assigned safe place or recycled. Do not discard 

them randomly.

IX. Safe Transportation

 

9.1 Loading and Unloading of Loader 

z  Danger always exists in loading and unloading 

of loader, which should be conducted very 

carefully. When loading and unloading, loader 

engine should be running at a low rpm, and 

loader should be traveling at a low speed. 

z  Loading and unloading must be conducted on firm and level ground with safe distance from 

roadsides being properly kept. 

z  Tires of carrying vehicle must be fixed during loading and unloading of loader to ensure that 

carrying vehicle will not move. Cushion blocks should be placed under gangboards. 

z  Gangboards used must have adequate strength with sufficient width and length to provide a safe 

slope for loading and unloading. The angle between gangboards and the ground should not 

exceed 15º, while spacing between gangboards should be adapted to wheel track of loader. 

z  Make sure that gangboards are firmly positioned with the same height on both sides. 

z  Make sure that gangboard surfaces are clean and free of lubricant, oil stain, ice and loose 

materials. Clean loader tires to remove dirt if any. 

z  Never steer a loader on gangboards. If necessary, reverse the loader to get off gangboards, and 

then adjust direction before driving onto gangboards. 

z  After the loader gets onboard, lock its steering mechanism and wedge the tires, then tie down 

the loader with ropes. 

9.2 Road Transportation 

z  In case the loader is towed by a trailer, provisions in national and local laws on weight, height, 

width and length must be observed. All related traffic regulations should be observed as well. 

z  Weight, height, width and length of loader should be taken into consideration when deciding 

transportation route. 

z  When passing bridges or constructions on a private premise, first check to see if whether such 

bridge or construction has an adequate strength to carry the weight of loader. When running on 

public roads, all related provisions must be understood and observed. Height of passages on 

transportation route should be surveyed to see whether the height is sufficient for a cabbed

loader to go through. 

z  When other means of transportation are to be used, the loader may need to be disassembled. 

Please contact Sichuan Chengdu Chenggong Construction Machinery Co., Ltd. Sichuan or 

authorized dealers for details. 

z  Slippage of loader in transportation or transfer should be avoided. Ice or other slippery 

substances on dock or train wagon must be cleared. 

9.3 Running 

Consult tire supplier on pressure and speed limit of tires. 

Inflate tires to a proper pressure value. 

Use a self holding inflating nozzle and always stand aside 

when inflating a tire. Refer to instructions on “Tire 

Inflation”. 

Add engine coolant, engine oil and gearbox oil to a proper level. 

Running of loader is subject to inspection by competent officials for approval if necessary. 

The loader should be running at a medium speed, and attention should be paid to all speed limit 

signs when running. 

Always carry out in-process inspection and check liquid levels in all parts. 

9.4 Lifting 

Lifting instruction is only applicable to short-time lifting of loader in short 

distance during the shipment of loader. Do not lift the loader for a long time when 

maintaining or servicing the loader, otherwise   

accident may occur to cause personal injury and death.

 

CAUTION 

Incorrect lifting may cause deviation of the loader and lead   

to personal injury or death and other losses. 

Weight and instructions given below only apply to CG958H   

wheel loader manufactured by Chenggong. Weight of CG958H is   

18400kg. 

1． Crane beam should be long enough to avoid contact with the loader.
