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. 

z  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. 

z  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. 

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. 

1.7 Housing rollover 

This machine adopts the integral rollover glass 

steel housing. In the left box of the counter weight, 

a housing rollover switch is available to realize 

housing rollover and enclosure. 

The rollover turns left to open the housing, 

vice versa. In the coursing of opening or enclosing 

the housing, if the housing fails to work, the 

switch shall not be pulled.

Prior to Starting Engine 

In-process Inspection 

Dismantle the front and rear frame fixed links and fix them 

on the rear frame. Prior to the dismantling of the frame fixed 

links, the loader cannot be started.   

For your safety and maximal service life, the in-process 

inspection shall be conducted prior to climbing up the loader 

and starting it. 

 Examine whether there exist screw loosening, garbage 

accumulation, oil or refrigerant leakage, damage or wear of parts at the surrounding or bottom of 

the loader. The working device and hydraulic components shall be examined. 

For the contents of daily in-process inspection, please refer to the “Maintenance per Ten Hours 

or Every Day” described in the chapter of “Maintenance” 

 

Examination Prior to Starting

 

Examine level of the hydraulic oil, engine oil, transmission fluid for torque converter, cooling 

fluid, and fuel etc. 

For the detailed maintenance contents, please refer to the “Maintenance per Ten Hours or 

Every Day” described in the chapter of “Maintenance”. 

Regulate the chair to facilitate the driver’s stepping on the pedal while leaning on the backrest.

 

Starting of Engine 

Normal starting: this loader is started under neutral gear protection, i.e. when the 
transmission operating rod is not at the position of neutral gear, the engine cannot be started. 

1.Turn on the master switch in the left box in the counter weight (Red handle faces ON 

position); 

2.  Make the shifting handle at the position of neutral 

gear; 

3.  Make the parking brake at the position of closure. 

4.  Make the control rod of working device at the 

position of keeping. 

5.  Insert the key to turn on the preheat start switch,

and then turn the preheat start switch to start the engine.   

Caution 

The starting time of the engine shall not exceed 5 seconds. Prior to restarting, the 

starting motor shall be cooled for 2 minutes. 

 

Starting of external power source 

 

Warning 

The accumulator can release the explosive flammable gas. 

Any spark near the accumulator is not allowed. The volatile gas produced by the 

accumulator will cause explosion. Mutual impingement of external power sources or of with 

loader is not allowed. 

No smoking as the level of electrolytic solution is examined. 

The electrolytic solution is acidic and will harm skin and eyes. After touching the 

accumulator and pile head, wash your hands. While maintaining the accumulator, it is 

suggested wearing gloves. 

While starting with the external power source, wear protective glasses. 

Improper connection of the external power source will cause explosion and personal 

injury and death. 

The anode (+) and cathode (-) of the accumulator shall be connected with the one 

respectively. 

The voltage of the external power source shall be consistent with the one of the loader, 

and the power source shall be the accumulator power source. 

Caution 

As another machine is used for starting, two machines shall not be contact each other so 

as to prevent the damage of the engine and electrical circuit. 

Use of external power 

Make a primary diagnosis for the loader that fails to start. 

1.Turn the joy stick of the transmission box of the choke to neutral position. Put all working 

devices down. All joy sticks are placed at the holding position. 

2. Turn the key switch of the choke to the central position and turn off all instruments and air
