CG958G Wheel Loader. Manual - part 6

- 28 - 

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: 

 Never clean with compressed air.   

 Do not brush or abrade materials containing asbestos.   

 For better cleaning result, clean with wet cloth or 

vacuum equipment with high efficiency dust/air 

separation filter screen.   

 Ventilate machining workstation of frequent use.   

 Wear proper breathing mask when there is no way to 

control asbestos dust.   

 Observe applicable laws and regulations in the work 

area.   

 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 

- 29 - 

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 machine, the lock rod shall be installed between the front 

and rear frames to keep the machine in a straight position. 

 

Lock rod 

Lock rod is painted with red warning color. When it is in a lock status, it can prevent perilous 

factors caused by relative movement of articulated front and rear frames in case of being under 

unpredictable foreign force. When the lock rod is in a lock status, the machine cannot run.   

The lock rod must be in a lock status in following circumstances: 

 During inspection, maintenance and repair of the machine; 

 When preparing to leave after finishing the work and stopping the engine each time; 

 When the machine is being hoisted; 

 During shipment of the machine; 

Fix 

1.  Keep the front and rear frames in a straight position.   

2.  Take off the rear split pin at the rear lug with a wrench, 

then take off the pin shaft from the upper side.   

3.  Rotate lock rod onward until the hole in the lock rod is 

concentric with the hole at front lug (see the picture).   

4.  Insert locking pin shaft from the upper side and fix it 

with split pin. The front and rear frames are now in a 

lock status.   

Release 

1.  Take off the split pin at the front lug, then take off the 

pin shaft from the upper side. 

2.  Rotate lock rod backward until the hole in the lock rod is 

concentric with the hole at rear lug (see the picture). 

3.  Insert the pin shaft which was taken off from the upper 

side and fix with the split pin. The front and rear frames are now in a free status.   

- 30 - 

 When servicing haudralic parts inside the front frame or front axle and the movable 

arm is needed to be lifted, the bucket shall be located on a solid platform to prevent it 

from falling and cause severe injuries. It is prohibited to have anyone stand 

underneath the bucket or movable arm when the machine is working.   

When working underneath the machine, the machine and its attachments shall be 

properly supported. Do not rely on hydraulic device to keep the stability of the machine. If 

the control mechanism moves or hydraulic pipeline leaks, any attachment may fall off.   

 

Instructions on use of protective safety stand for lift cylinder 

Protective safety stand for lift cylinder is a safety protective device. It is fixed at the rear frame. 

Before servicing the wheel loader, it shall be removed from the fixing position and installed at 

the indicated places of the lift cylinder (as shown in the diagram). The orders of the removal 

and installation is as follows: 

1.  Remove the protective device; 

2.    Install it at the specified positions of the lift cylinder (two places at the left and right side of 

the oil cylinder); 

 

 

 

 

 

 

 

 

 

 

 

 

文本筐

: Fix the safety stand for oil cylinder into the piston rod of oil cylinder when repairing. 

When not repairing, fix the protective device for the oil cylinder at the right side of the rear 

frame.

3.    Install and fasten tightly its fixing bolt. 

 Unless otherwise specified, no adjustment shall be made when the machine is working or 

the engine is running.   

 At the linkage mechanism of the work device, in accordance with the movement of the 

work device, the space at the linkage mechanism may increase or decrease.   

 Keep away from all rotating and moving parts. 

 Ensure that there is no any foreign matter between the fan blades. Fan blades will throw out 

or cut the tools or other foreign matters which fall inside or are pushed inside. 

 Donot use twisted or worn wires or cables. Weare gloves when handling wires and cables.   

 When removing bouncy objects, such as snap ring or closing ring, wear protective goggles 

to protect eyes. Take care to check whether anyone is nearby in case injury being inflicted 

to other people.   

 When dissembling parts by hammering, fragments may fly over. Take care not to cause 

injuries.  

3.8 Precautions in Using FOPS & ROPS (falling object protection structure 

or rollover protection structure) 

The rollover protection structure (ROPS) and falling object protection structure (FOPS) of 

the wheel loaders of Chengdu Contruction Machinery Co. Ltd are integrated with the cab. The 

FOPS & ROPS are for protection of operator in case of heavy objects falling down from above 

or rollover of the machine. The ROPS will not only bear the load when the machine is rolling 

over, but also absorb impact energy.   

 If the device is damaged by falling or rollover, its strength will decrease and it will be 

unable to perform its protective functions. For this instance, please contact with Chengdu 

Contruction Machinery Co. Ltd or its approved dealers to consult for repair method.   

 Even if the POPS is installed, the operators must fasten safety belt for effective protection. 

Even if no defect is discovered of the safety belt, it shall be replaced evrey three years.   

 It is prohibited to bore or weld inside or outside of ROPS, otherwise the strength of ROPS 

may be lowered. The protective performance of FOPS & ROPS will be weakened if the cab 

is damaged or turnover occurs.
