CG958G Wheel Loader. Manual - part 24

- 100 - 

emergency brake system. Both are controlled hydraulically. The control button is designed at the rear 

side of the control rod of the working device. 

Caution 

The medium of this system is hydraulic oil same as the other hydraulic systems, so other 

brake liquid is not required. 

This system carries out the international standard ISO 3450-1999. 

 

Caution 

Only the parking brake oil pressure is over 10.3MPa, the parking brake may be loosened. 

Therefore, when the loader is running and the oil pressure is less than 10.3Mpa, the parking brake 

will automatically damp. Therefore, the driver shall watch out the parking brake alarm lamp. 

Running the loader under the state that the parking brake is closed is not allowed. 

Do not use the parking brake while driving under exceptional circumstances, or not, the 

parking brake will be damaged seriously.   

Close parking brake--Press the control handle of the parking brake (1) to close the parking 

brake. 

Loosen parking brake--turn clockwise the control handle of the parking brake (1), the handle 

will bounce automatically to loosen the parking brake. 

Warning 

After starting and preheating of the engine, if the low brake pressure alarm lamp lights 

continuously, the engine shall be stopped immediately for examination. After the alarm lamp 

lights off, the engine may be operated, or not, your driving safety would be endangered. In case 

the brake pressure alarm lamp lights during the period of drive, it shall be stopped immediately 

for examination. 

Caution 

Welding and mechanical processing on the shell of the accumulator are not allowed. Upon the 

completion of the connection, the hydraulic pipes shall completely discharge the air through screw 

plug on the accumulator. The repairing and pressure connection relating to the accumulator etc may 

be conducted after the oil pressure is released.

1.4 Control Pedal 

Accelerator pedal (1)--The journey under the pedal 

decides the oil supply amount of the diesel engine. 

Service braking pedal (2)--In service, step on the 

pedal (2) to reduce speed or stop the loader. 

1.5 Flameout Switch 

This loader adopts electric control. It is installed with the electric controlled flameout device, 

i.e. electric lock on switch board. Turn off the electric lock to flame out the engine. 

1.6 Control of Working Device 

Precautions: 

The hydraulic oil deployed by the hydraulic system must be cleanly. 

After the moving arm or rotary bucket is controlled to the wanted position, the pilot-operated 

control handle shall be back to the central position firstly.   

Do not lift the bucket to the highest position to deliver materials. In transportation, the interface 

point under the moving arm shall be kept for 500mm away from the ground so as to ensure the 

stable service of the loader. 

Prior to each service, the liquid level of the hydraulic oil box shall be examined to ensure the 

proper oil amount. 

The pilot-operated control handle shall be examined whether it stays at the central position. 

Examine whether the function of the lock-up solenoid valve of the handle (pilot-operated oil 

supply valve band) is normal. 

Operation: 

Usually, the operation way of the loader is joint operation with camion. If the camion stops, the 

loader loads skidly. The camion and loader works jointly. 

 

Lifting Control of Bucket 

Descend and fluctuation--Push forwards joy stick (1) to lay 

down the bucket. If push it forwards 

further, the bucket fluctuation may be

realized. 

Keeping--Move back the joy stick (1) to the central position from the lifting or decreasing, 

fluctuation position, and the bucket may stay at its original position.   

Lifting--Pull backwards joy stick (1) to lift the bucket. 

 This loader is equipped with a lifting limit system. When the bucket is pulled backwards 

to lift the operating rod, the operating rod will be absorbed under the action of 

electromagnet to make the moving arm finish the lifting automatically until going up to 

the limit position. Meanwhile, the electromagnet will release the operating rod back the 

central position and stop the lifting of the moving arm. The different lifting elevations of 

the moving arm may be attained by adjusting the position of the electromagnet installed 

on the moving arm.   

 

Bucket Reversion Control 

Reversion--Pull outwards the joy stick (1) for bucket’s reversion forwards. 

Keeping--loosen the reversed joy stick (1) to make it back to the central position. The bucket will 

stay at its original position. 

Take back--Pull the joy stick (1) inwards to take back the bucket. 

 This loader is equipped with a bucket auto-leveling device. After the bucket unloads, you 

may pull the bucket backwards to reverse the operating rod. The operating rod will be 

absorbed under the action of the electromagnet and finish bucket reversion 

automatically (the descent of the moving arm may be operated at the same time). As it 

reverses automatically to the bottom of the bucket and stays at the level position, it will 

automatically stop reversion. This process is named as the auto leveling. Its purpose is to 

improve the operation efficiency. The bucket bottom level or inclination the lifting 

elevations of the moving arm correspond to may be attained by adjusting the position of 

the electromagnet installed on the cylinder of turn trolley to meet various working 

requirements. 

Loading: 

Advance to stockpile by II gear. When the loader reaches the near area of the stockpile, shift to 

I gear. Descend the moving arm to make the distance of the interface point under the moving arm   

away from the ground about 500mm.The bucket shall be parallel to the ground. 

- 103 - 

As the bucket has a distance of about 1 meter away from the stockpile, the moving arm may be 

descended to make the bucket near the ground level and into the stockpile. 

As the bucket cuts into the stockpile amain, if the resistance is strong, the turn the bucket 

upwards and lift the moving arm discontinuously for full load. 

After the bucket is filled, lift the moving arm to certain elevation, and turn the handle back to 

the central position. 

Unloading: 

Load all or partial materials slowly by controlling reversion handle so as to weaken the impact 

force of the materials against the camion. If the materials are stuck on the bucket, the materials may 

be unloaded by means of reversing and shivering the bucket repeatedly. 

In order to prevent improper operation of the handle after parking and act of moving arm, the 

loader is equipped with a handle lock-up solenoid valve. The pilot-operated oilway shall be shut 

down firstly prior shutting off the power of the solenoid valve. At this time, if you operate the handle, 

the working device will not work. In working, power the solenoid valve.
