Children's play toy excavator excavator is a full simulation, have dug deep down, 360 degrees, 180 degrees, or 90 degrees of rotation, through his open hands to experience the fun of the excavator is the best choice for the park's rides. ? Help First, the machine steady expansion bolts in place using a solid flat surface, and the installation of the fence, the fence nearest distance itself should be more than 1.5 meters. Second, this machine uses 220v AC power, use with leakage protection switch and ground power supply voltage in order to ensure stable and reliable power supply line should be 3 * 2.5 square copper, 2 meters away from the main power supply. Third, before use of hydraulic oil filling, it is recommended to use the brand of hydraulic oil, the oil must be counted among the 80-90 level. Fourth, work equipment joints should be filled with oil. Five consecutive starts for the first time the boot should stop more than three times, and the empty run over five minutes to eliminate gas pipeline in ??. (Winter temperatures below 0 degrees before starting the day idling five minutes preheat) before six, machine debugging appearances are normal, moderate speed, the speed to be adjusted as described below, refer to: 1. hydraulic valve control device above the speed can be adjusted The pressure regulator, clockwise to increase pressure, counter-clockwise to reduce the pressure (for the whole pressure) 2. Adjust the speed of a single action, adjustable hydraulic valve in the middle of the control valve, the corresponding work for every single action turn it clockwise to reduce the pressure, counterclockwise rotation as the pressure increases, the amount of rotation because of need. ? ?? 3 Fence Installation: 1.4 * 1.5 meters on both sides of the protective net 2 and a height of 1.5 meters, after the ???????? 0.75 * 1.5 m protective net, previous 0.6 * 1.2 m Protection Network 2 and the upper side is flat, the next leak yellow iron, 0.6 * 1.2 m protective net and machine pedal at M5 bolts connected by serial number with M5 * 5 cm bolt connected. History of the development of children's play in Japan and South Korea and other developed countries excavator has been popular for several years, has just started in China, the introduction in 2011 of production (currently the only manufacturer), into the market response is good, the majority of users of all ages . ? Note ? Use with a three-wire power leakage protection and ground. ? This machine uses the ambient temperature should be 0-38 ℃, there may be unsuitable for use where water splashes. The machine should be placed on stable ground. · Winter when the outdoor air operation in 5-10 minutes. · Long-term disabled should cut off the power. · Prohibit the operation in the case of young children unattended. · Always check the equipment for loose screws, pins is off, on a regular basis to work the device connecting parts add oil. 1-2 years to decide whether to replace the hydraulic oil based on oil properties. ? Security Knowledge troubleshooting motor does not start to see whether .1 AC contactor connected firmly, 2 connectors for virtual access voltage is stable too loud? 1. Hydraulic oil tank at reducing oiling no oil, 2. no butter voltage is too large leak oil, oil leakage? 1. Replace the drain / permeability tubing at the ring? 2. Tighten the oil spill at the bolts, nuts, no flashing lights speakers do not sound 1. Check connectors are securely without virtual connection 2. Adjust the controller to adjust volume flash. ???
