CAUTION 

 

When replacing rubber tube assembly in motor, loader engine should be shut off first to release 

pressure and cool down hydraulic oil (to a safe degree) before the replacement is made. 

 

IV. Safety marks 
All safety marks and meanings thereof for cooling fan control units will be described here. Operators must

Cigarette lighter (26); 

Standby socket (85);   

Fuel gauge (38)--Indicating the oil level of the fuel box; 

Transmission fluid pressure gauge (39)--indicating the working oil pressure of the transmission case. 

The normal value is 1.6~1.8Mpa. 

Emergency turning switch (87)--Press this button to start the emergency turning system. 

Caution 

It is suggested to use the emergency turning system under the circumstance that urgent 

turning to avoid obstruction is required as the paroxysmal normal turning system fails or 

engine shuts down. 

Warning 

If the emergency turning system is started frequently, the emergency turning unit will be 

damaged possibly. 

The electrical control system of this loader mainly is composed of two parts including 

electronic spray engine control system by CAN bus control and control system for accessories 

including lighting, signal and alarm indicators, air conditioning, lifting control and leveling control 

etc.

   

   

Warning 

Improper external power connection will result in personal injuries and death due to 

explosion. Accumulators connected in series shall be installed in a separate accumulator box. 

As the external power source is used, the cable joint (+) shall be connected with the 

accumulator’s joint (+) connected with the starter coil. The cable cathode (-) of the external 

power source shall be connected with the one of the starter. In case the cathode of the starter
