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: 

z  During inspection, maintenance and repair of the machine; 

z  When preparing to leave after finishing the work 

and stopping the engine each time; 

z  When the machine is being hoisted; 

z  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.   

z  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 are given 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); 

 

 

 

 

 

 

 

 
 
 
 
When not repairing, fix the protective device for the oil cylinder at the left and right sides of the rear 

frame (each side one respectively). 

 

 

 

 

 

When repariring, fix the 

protective device on the 

rod of the cylinde

r.

3.    Install and fasten tightly its fixing bolt. 

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

engine is running.   

z  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.   

z  Keep away from all rotating and moving parts. 

z  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. 

z  Do not use twisted or worn wires or cables. Wear gloves when handling wires and cables.   

z  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.  

z  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 Sichuan Chengdu Construction 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.   

z  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 Sichuan Chengdu 

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

z  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 every three years.   

z  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.   

3.9 Proper Handling of Waste   

In order to prevent pollution, especially in the places where people or animal abide, the 

-  - 

29

following requirements must be observed:

 

z  Use leakage proof container when discharging liquid. It is not allowed to dump waste liquid on 

ground, sewage or water source site.   

z  When handling harmful materials, such as lubricant, fuel, coolant, solution, filter, storage 

battery and other materials, observe the relevant laws and regulations.   

z  The replaced waste tires shall be stored in specified safe place or be recycled. Do not dispose of 

randomly.  

3.10 Prevention of lightning injuries 

   When lightning occurs near the machine, the operator is prohibited to carry out following 

procedures: 

z  Climb up the machine.   

z  Get off the machine.   

If you are in the cab when lightning occurs, please remain in the cabin. If you stand on ground when 

it occurs, you should stand at a place far from the machine during the lightning period.
