HELI OPSM - Battery Replacement; Common Fault and Troubleshooting

10.2 Truck transportation:
If the truck will be transported for a long distance, support the end of truck close to driver with wood
beam to make the drive wheels away from ground; fix the two front wheels with wood wedge, and fasten
the truck with the transportation vehicle with ropes.
10.3 Truck loading/unloading:
Before load or unload the truck, please first check the total weight marked on the nameplate, and
choose the proper hoisting device. Keep horizontal during hoisting and touch the ground slowly. People
around should take care, and the operation should be guided by another person. If load or unload with a
vehicle, first observe the bottom condition of the truck under loading/unloading. Operate cautiously when
the forks are inserted into the truck bottom to prevent forks from damaging the drive wheels, balance
wheels and front wheels of the truck.

Open and take down upper cover of truck;
Pull battery connector out of truck body;
