2. When the traveling motor is started, pay attention to the forward and backward speed of the drill. When towing, do not stay or walk between the two machines
3. When connecting and removing the drill pipe, the spindle of the rotary head must rotate slowly to prevent the fork and the J-shaped wrench from slipping and rebounding;
4. The jack is only used for leveling the drilling rig and loading and unloading during transportation. It is strictly prohibited to deal with stuck drilling accidents.
5. When the drilling rig is displaced, the drilling rig can only be moved when the carriage is completely upright and fixed with bolts or the carriage is completely flat.
