(2) Duster of two side beams;


(3) Saw blade protective hood;


(4) Horizontal and longitudinal tow chain;



  1. Function of safety protection device


When any safety protection switch or emergency stop switch acts, the safety relay will act immediately to cut off main circuit power to avoid accident.



  1. Enabling of safety protection device


When main power supply is switched off or after a certain switch motion, to keep all safety protection switch and emergency stop switches effective and maintain normal operation of safety relay, you shall press Reset button on the panel when safety relay is energized. Otherwise, safety relay cannot operate normally and main circuit power supply cannot be switched on.



Eight. Maintenance, Repair and Calibration


(One) Notice



  1. Maintenance of electrical parts shall be made by maintenance personnel with relevant qualification, and other persons shall not open the electrical cabinet in order to avoid hazard or damage to electrical control parts;

  3. Power service wire shall be equipped with circuit breaker to cut off power supply during maintenance to avoid electric shock;

  4. When machine is not in use, cut off the general supply to ensure safety;

  5. Electrical control cabinet and hydraulic station part of machine shall be provided with relevant waterproof measures to avoid damage to electrical control parts by water;

  6. Please read these instructions carefully before operate this machine;

  7. In case electrical parts of machine are damaged due to unsteady supply voltage of user, misoperation or lightning strike, it shall be of accident damage;

  8. Please click touch screen with sharp and hard object when set data to avoid touch screen damage;


(Two) Daily maintenance and service



  1. Maintenance


(1) Check and fasten fasteners of frame and driving member once every two months;


(2) Check and fasten fixing of each hood once every half month;


(3) Check and maintain electrical control system once every half month;


(4) Maintenance of motor and bearing shall be made according to requirements of SEW and SKF.


(5) Pull lubrication apparatus on rotation inner drum 5-10 times before operation every shift to inject lubricating oil to each position and fill lubrication apparatus with lubricating oil.



  1. Service


(1) Exposed gear engagement shall adopt manual periodic lubrication with No.2 lithium based grease and the lubrication interval shall be half month or when there is no grease at gear engagement;


(2) Gear case shall adopt manual periodic lubrication with No.2 lithium based grease and the lubrication interval shall be 12 months or when there is no grease in gear case;


(3) Service of motor and bearing shall be made according to requirements of SEW and SKF;


(4) For lubrication of other parts, please refer to Figure 7.
