II Operation Technology 

2.1 Common Technology 

In operation, in order to widen the drivers’ vision and 

stabilize loading, the bucket shall be lowered and kept about 

40cm above the ground. 

 

Use the wait time to level the working area. 

 

Avoid more stress of the bucket to make the loader have 

enough tractive force. 

 

 

 

 

 

 

 

 

Use cutting teeth to load the relatively hard materials. 

In bucket reversion, the joy stick (1) shall     be 

placed at the position of bucket reversion. And then turn 

back it to the original position. Repeat the operation until 

materials are unloaded. 

 

In order avoid dust into the engine and keep visibility, 

the bucket shall be reversed leeward. 

Ensure the bucket is consistent with working 

requirements. Overload will shorten the service life of the 

loader.

Scraping 

Note:  Scraping is not allowed as the bucket is at the forerake position so as to 

prevent the bucket from damage. 

In scraping, the bottom of the bucket shall be parallel to the ground. 

Bucket Reversion 

Use the bucket stopper for maximum reversion angle. 

z  Unnecessary repeated collision with the stopper will accelerate its wear. The charge of 

repairing linkage gear of the working device is very high. 

2.2 Loading of Stockpile 

1. Level the bucket and scrape the ground slightly. Hold advance I gear to make the bucket 

directly insert into the stockpile. 

2. Make the joy stick of the moving arm at the position of lifting, and operate the joy stick of 

the bucket to make the bucket incline backward slowly for 2-3 times for full loading.   

3. After the bucket is filled, the bucket stays at the backrake position, and the joy stick of the 

bucket stays the central position. 

4. Lift the bucket enough high to avoid the stockpile. Make the transmission control rod at the 

reverse gear to drive the loader backwards. 

5. As the loader reverses to the certain position, lay down the bucket to the transport position 

about 40cm away from the ground. Push the transmission control rod to the required gear to 

transport the materials. 

6. As the loader reaches the reversion unloading area, make the joy stick of moving arm at the 

position of lifting until the bucket unloads all materials.

2.3 Loading with A Truck 

For the four loading methods above, the operation method with a short cycle time (for 

one time of loading) may be chosen depending on the situation on site. 

1.  Enough distance shall be available to make the bucket reach the lifting height prior to the 

loader reduce the speed. 

2.  Place the bucket at the middle of the truck to unload materials. In case the length of the 

truck body is two times of the bucket, the materials shall be unloaded to the back from the 

front of the body. 

3.  Advance the joy stick of the bucket to reverse the bucket. 

4.  Shake off the materials stuck on the bucket. Rapidly push and pull the joy stick of the 

bucket to make rocking arm touch the stopper. 

5.  Make the joy stick of the bucket at the position of taking-back bucket. 

6.  Prior to laying down the bucket, please note whether the truck is outside the bucket. 

7.  Lay down the bucket as another bucket will be installed on the loader. 

z  Unnecessary repeated collision with the stopper will accelerate its wear. The charge of 

repairing linkage gear of the working device is very high. 

2.4 Loading of Hard Soil 

z  The collapse of materials will cause personal injuries and death.

z  Remove suspender and note the materials slid. 

1.  Load hard soil from the bottom to the upper surface 

2.  Lift the bucket slightly and leave the soil stack. 

2.5 Excavation 

1. Lay the bucket on the ground and make it have a small excavation angle. 

2. Prior to the loader advances, press the bucket downwards, and make the lifting joy stick of 

the moving arm at the position of holding when the bucket reaches the enough depth. 

3.  Keep the bucket leveled scraping and excavation by lifting and laying down the bucket. 

4.  As the bucket is filled, take back the bucket to make it run against the stopper. Drive the 

loader to the material unloading position when the bucket is away from the ground for 

40cm. 

2.6 Loading to Bucket 

1.  Fill the bucket (See “Loading of Stockpile”). 

When the bucket reaches the lifting limit position, materials may be loaded to the chopper 

leeward if possible.53 

2.7 Application of KD Key 

The KD key (1) is designed at the topside 

of the speed operating rod with the purpose to 

improve the operation efficiency. Its application 

technology is given below: 

1. As the loader advances to and near the stockpile 

at the speed of II gear, press the KD key (1), and 

whole machine will be at the speed of I gear from 

the previous II for maximum tractive force. 

2. As the shifting handle is turned to the reverse direction upon the completion of loading work, 

the loader will back to II gear automatically (reverse and advance are II gear) for the relatively 

high speed to finish the loading work; 

3. Repeat steps 1~2 to use the KD key for a higher operation efficiency.
