(2)  Digging Operation 

„  Digging Piled Soil or Blasted Rock 

When digging piled soil or blasted rock, the loader should face the 

material and do as follows: 

 

z  If the bucket must be lowered while driving the machine forward, 

stop the machine when the bucket is about 30cm above from the 

ground, and then lower it slowly.   

z  If the bucket hits the ground, the front tires will leave the ground 

and the tires will slip. 

z  The operator must slow the speed immediately when the machine 

reaches the material pile. Simultaneously step on the accelerator 

pedal, and enter the material pile with the bucket. 

z  Keep the bucket horizontal when loading the stockpile, but keep 

the dumping angle down when loading the blasted rock. 

 

 
Notice: 

Do not let the blasted rock go under the bucket which will make the front tires leave from the ground 

and slip. Try to hold the load in the center of the bucket; otherwise, if the load is on one side of the 

bucket, it will be unbalanced. 

 

z  Raise the lift arm to prevent the bucket from inserting too deeply 

while thrusting the bucket into the material. The tires will bring 

ample traction by raising the lift arm. 

z  If enough material is loaded into the bucket, operate the working 

equipment control lever to take back the bucket in order to load it 

fully.  

Remark: 

If the shovel edge moves up and down when thrusting material into the 

bucket or when digging, the front tires will leave the ground and slip. 

z  If there is too much material loaded into the bucket, the bucket 

must be dumped and titled quickly to remove the excessive load so 

as to prevent the material from dispersing during transportation.

„  Digging and Shoveling Material on Flat Ground 

Lightly set the bucket edge leaning on the ground (see 

picture) when digging and shoveling material on flat 

ground. Be careful not to fasten the load to one side 

which will cause unbalance. This operation should be 

carried out carefully in gear .

Ⅰ

 

z  Lightly set the bucket edge facing down. 

z  When driving the machine forward, operate the working 

equipment control lever to let the lift arm lower down to 

the proper position so that it can pick up a thin layer of the 

surface each time when excavating the soil. 

z  When driving the machine forward, shift the working 

equipment control lever backward and forward slightly to 

reduce the resistance.

NOTICE

 

Keep the two sides of the bucket cutting into the material equally 

to prevent only a single side working. Face the loader forward and 

never let an angle exist between the front and rear frame. 

 

 

(3)  Conveying Operation Without Truck 
The loader must be used without a truck under the following conditions: 
z  The ground is too soft and not level, and the truck can not be used. 
z  When the transportation distance is within 500 meters, it is not economical to use a truck. 
z  The transportation driving speed is determined by the road condition. 
z  In order to get good visibility and stability, the bucket should be turned to its upper limit 

location(bucket lift-arm touch the upper limited block) and keep the lower pin connection point 
of lift-arm at the transportation position (400~500mm above the ground).

(4)  Dumping Operation 
z  When dumping material on to trucks or into freight 

yards, raise the lift-arm to the position (forward tilt 
to the maximum position) where the bucket does 
not touch the carriage or material pole. And 
operate working equipment control lever to tilt the 
bucket forward to dump. Part or all of the material 
can be dumped by the lever control. Act slowly 
and gently during dumping to prevent the bucket from striking the ground. 

z  If the material sticks onto the bucket, move the working equipment control lever cyclically to 

allow the bucket to tilt forward or backward to shake down the material. 

z  After dumping, use the bucket to level equipment (if assembled). Rear tilt bucket to level position, 

and operate the working equipment control handle to allow the lift arm to lower to prepare for 

next operation. 

 

(5)  Pushing Operation 

Level the bucket to the ground, and push the 

accelerator to move forward. If there is blockage during 

moving, raise the lift arm a little and move forward 

continuously. When operating the lift arm to lift or 

lower, operate the control lever between lifting and 

lowering operation. Never use the lever at the raising 

or lowering position to ensure pushing the bucket 

smoothly.

NOTICE

 

Watch the torque converter oil temperature gauge all the time 

during a pushing operation. If the temperature is too high, stop 

the machine to let it cool down and then continue to work.

(6)  Striking Operation 

Tilt the bucket to let the blade touch the ground. 

For hard ground, put the lift arm control lever in the 

float position; for soft ground, put the lift arm control 

lever in the neutral position. 

Use reverse gear to strike the ground with blade. 

 

(7)  Towing Operation

!  

WARNING

 

Before towing, the tires must be blocked by the parking brake to 

prevent the machine from rolling. 

During towing, be careful to prevent severe and fatal injury. 

z  If possible, the engine of the towed machine should keep the engine running to ensure braking 

and turning is possible. 

z  If the towed machine engine can not start, disassemble the front and rear transmission axle. If the 

machine can not turn, disassemble the steering cylinder. 

z  The connection hole of the rear frame at the inner side of the rear wheel can only be used for 

lifting and binding, but not for towing. 

z  If there is no braking system for the towed machine, never use soft towing but use fixed towing 

or use towing bar. Connect the towing bar to the towing pin at the back of the loader. 

z  If there is no braking system on the towed machine, no one is allowed to stay on it. 
z  Check whether the towing rope and towing pin are strong enough to suffer the weight of the 

towed machine. If machine will pass over clay ground or go up a slope, two towing ropes and 

towing pins should suffer at least 1.5 times the weight of the towed machine. 

z  Try to decrease the towing angle of the towing rope to ensure that the angle between the towing 

rope and the towed machine is within 30°. The height of the towing points of the two machines 

should be close. 

z  The connection between the towing equipment and the machine should be strong. 
z  The weight of the towing machine should be heavier than the towed one, and have enough 

traction power and braking power to be able to pull or brake two vehicles going up and down a 

slope. 

z  When towing the machine down a slope, the machine should have sufficient traction power and
