z  Ether is a toxic and combustible object.   

z  Injury will be resulted from inhalation of ether vapor or frequent skin contact with ether.   

z  The area shall be well-ventilated where ether is used.   

z  Do not smoke when changing ether container.   

z  Take care to prevent fire when using ether.   

z  Do not put replaced ether container at living area or in the cab.   

z  Do not put ether at places under direct sunshine or where the temperature is over 39℃(120°F).  

z  Put discarded ether container at safe place. Do not perforate it or heat it.   

z  Keep ether container at place which is not accessible for non-staff.   

3.6 Precautions for Burnings and Other Injuries 

Coolant 

z  When the machine is working or has just finished working, the engine coolant is hot and is 

pressured. All the tubes from radiator to engine contain hot water or steam; severe burnings will 

be inflicted by contacting with them.     

z  When checking the coolant level, the engine shall be at the status of stopping and screw off 

slowly the filler cap of cooling system to check the fluid level (screw off slowly to vent the 

pressure).   

z  When it is needed to discharge the coolant, allow the coolant cool down completely before the 

discharge.  

Oil  

z  Hot oil or hot parts may cause injuries. Please take care not to touch hot oil or parts to avoid 

skin burning.   

z  When the machine is working or has just finished working, the hydraulic oil’s temperature is 

high and the oil is pressured.   

z  When opening the filler cap of hydraulic oil tank, the engine shall be stopped and screw off 

slowly the filler cap (screw off slowly to vent the pressure). 

z  Before opening the hydraulic oil tank cover, any tube or joint or dissembling parts, please vent 

their pressure firstly.   

z  Please do not knock or bend high-pressure tubes.   

Accumulator 

z  Must inspect accumulator before filling nitrogen. It is prohibited to fill gas in if the accumulator 

-  - 

23

is not installed with plate, the contents on the plate is not complete or not able to be recognized, 

or defects on the body which may affect safe use of it.   

z  The accumulator is only allowed to fill in nitrogen. It is prohibited to fill in oxygen, compressed 

air or other combustible gas to avoid explosion.   

z  The accumulator is a high-pressure container and shall be maintained or changed by 

professional manufacturers. Before dissembling the accumulator, pressure must be vented and 

nitrogen inside the bladder be discharged with special tools. Then the parts can be dissembled.   

Storage battery 

z  Storage battery will release combustible smoke that may cause explosion.   

z  Do not smoke when checking the electrolyte of the storage battery.   

z  Electrolyte is an acid material that will cause injury when in contact with skin or eyes.   

z  Wear protective goggles when working on storage battery.   

Pipeline, tubes and hoses 

z  Do not bend or hammer high-pressure pipelines; do not install damaged tubes or hoses on the 

machine.  

z  When repairing any loose or damaged fuel or lubricant tube or hose, any leakage may cause a 

fire. Please take care to ensure safety.   

z  Inspect the pipelines, tubes and hoses. Do not check for leakage with bare hand. Check for 

leakage with a piece of board or cardboard. Fasten all joints with specified torque. When any of 

the following troubles is discovered, shall make replacement.   

1. Damage or leakage of joints.   

2. Wear-out of or cut on out layer and bareness of reinforcing wire.     

3. Local bump of outer layer.   

4. Obvious twist or flatness of hoses.   

5. Wire in reinforcing layer is embedded into outer layer.     

6. Displacement of end joints.   

Ensure correct installation of all pipe clamps and guard plates to avoid vibration and consequent 

overheat by friction with other parts when the machine is working.   

Tire 

Explosion of tire full of gas results from heating and combustion of the gas inside the tire. Heating 

is usually caused by welding or heating of wheel rim or flames. Or it may be caused by gas 

-  -

combustion resulting from overuse of brakes.   

Explosion of tyre is much powerful than deflation. Explosion may cause tyre and wheel rim to fly 

away as far as 500 meters. Explosion and its fragments may result in injuries and property damages.   

Do not stay in the range indicated in the following diagram. 

 

 

 

 

 

 

 

Recommend inflate tyres with dry nitrogen (N2).If there is already air inflated in the tyres, 

recommend use nitrogen to adjust pressure. Nitrogen can be blended with atmosphere air.   

Tyres inflated with nitrogen are less probable to explode, because nitrogen is not combustible. 

Besides, nitrogen helps prevent ageing of rubber and corrosion of wheel rim parts.   

Proper equipment and training is desirable to avoid overinflation. Leakage or damage of wheel rim 

are caused by improper inflating equipment or improper use of it.   

Compressed air 

z  Compressed air may cause injuries. When clean 

with compressed air, wear mask, protective 

clothing and shoes.   

z  The maximum pressure of compressed air used 

for cleaning shall be lower than 0.205Mpa. 

Leakage of solution 

At least 500m 

At least 15m 

-  - 

25

Use board or cardboard to check for leakage. Even the leakage of pressured fluid as minor as a 

needle eye may penetrate muscles and cause injuries. If solution is jetted to skin, it shall be treated 

within a couple of hours by surgeons who are familiar with this kind of injury.   

Asbestos 

When handling parts that contain asbestos fiber, it shall be avoided to inhale in asbestos dust, which 

is harmful. The products of Chenggong that contain asbestos are brake pad, brake plate and some 

gaskets, the asbestos inside which are normally sealed with colophony or by other means. As long as 

no air containing asbestos is generated, normal handling is harmless.     

When asbestos dust is generated, follow the precautions below:     

z  Never clean with compressed air.   

z  Do not brush or abrade materials containing asbestos.   

z  For better cleaning result, clean with wet cloth or vacuum equipment with high efficiency 

dust/air separation filter screen.   

z  Ventilate machining workstation of frequent use.   

z  Wear proper breathing mask when there is no way 

to control asbestos dust.   

z  Observe applicable laws and regulations in the 

work area.     

z  Store asbestos in compliance with relevant 

environment laws and regulations.   

3.7 Precautions for Crush or Cutting 

During the operation of the machine, the space 

between the front and rear frames is not allowed to 

be entered.

 

When the machine is hoisted and loaded on other 

machines, or when servicing at the middle of the 

machine, the lock rod shall be installed between the 

front and rear frames to keep the machine in a straight 

position. When the machine is hoisted and loaded on 

other machines, or when servicing at the middle of the
