insulator). 

z  At least 6m (20ft) at 40KV high voltage condition (electric wire is generally supported by 

hanging insulator). 

The vertical distance between loader and the overhead electric wire should be: 
z  At least 2m (6.5ft) at low voltage condition. 
z  At least 4m (13ft) at high voltage condition. 
To prevent an accident, please do as follows: 
z  First ask the electricity company for the voltage. Check the validity of action according to the 

relevent rules when the machine may touch the electric cables. 

z  Wear rubber shoes and rubber gloves. Lay a leather cushion over the operator’s shoes. Be sure no 

part of your body can touch the metal bottom. 

z  Assign a signal warner, who can give a warning when the machine gets too close to electric 

cables. 

z  Never leave the operator cab, never move and do not touch any part of the machine until the 

people who are on the ground cut off the electricity once the machine touches the wire. 

z  When operating near high-voltage cables, make sure other persons are far from the machine. 
 

7 SAFETY PARKING 

7.1 Pay Attention to the Safety of Yourself and Others 

z  Park the machine on level ground. The working equipment should be put on the ground. 

z  Never park on a ramp. If parking on a ramp is necessary, the ramp angle should be less than 20%, 

and put the wedge under the wheels to prevent moving. Then put the bucket down to the ground. 

z  If the machine is disabled or must park in a high traffic area, lay bars, signals, flags and warning 

lights. Make sure the other cars can see it clearly. Do not block traffic.

7.2 Notice for Cold Area 

z  Clear the water, snow or dust attached to wires, switches, power insert or sensor and the covers of 

these parts. Otherwise, the water in these parts may be frozen and an unpredictable accident may 

be caused. 

z  Before operation, preheat sufficiently. The machine won’t start if do not preheat before operating 

the conrol handle of the working equipment and an unpredictable accident may be caused. 

z  Operate the working equipment control handle to let the hydraulic oil cycle in the hydraulic 

system (Do this by letting the pressure of the system rise up to the system setting, and then 

release to let the oil flow back to the hydraulic oil tank ) to preheat the hydraulic oil, so as to 

guarantee better reaction and prevent malfunction. 

z  Do not charge the storage battery with frozen electrolytes, and do not use other power to start the 

engine. It is dangerous and can cause fire. Please refer to 

CHAPTER III 3.5.3 Operation

8 SAFETY EXAMINATION AND REPAIR 

8.1 General Knowledge 

z  Operation and maintenance people should be trained 

to become the licensed. Do not allow anyone to enter 
the working area except the maintenance people. If 
necessary, please assign people to guard. 

z  The repair of the machine should follow the 

procedures. Ask the Shandong Lingong Construction 
Machinery Co. Ltd. for help if you don’t know how 
to do the repair. 

z  Assure that the people who are responsible for 

repairs, who decide the working procedures, who 
determine the person in charge and repair the
