introduction： Manual forklift use precautions Before the start，You should look around first，After confirming that there are no obstacles hindering the safety of driving，First whistle and then start;Do not raise the fork too high while driving。 In and out of the work site or on the road，Pay attention to the presence of obstacles in the sky。 When carrying a load，If the fork is raised too high，It will also increase the overall center of gravity height of the forklift，The stability of the forklift is affected; When turning a corner，If there are pedestrians or vehicles nearby，The signal should be given first，Sharp turns at high speeds are prohibited。
