2. After extending the ladder, keep the overlapped part at a certain overlap distance. The overlap distance of ladders under 8 meters should be more than 75 cm, and the overlap distance of ladders over 8 meters should be more than 110 cm.
3. When raising and lowering the ladder, you should hold the handle with one hand and the rope while lifting. The palm of your hand must not be placed on the ladder step, otherwise you may get your fingers stuck while lifting the ladder.
4. Lift to a suitable height. After ensuring that the lifting clip is stuck to the step, remove the fixed block at the bottom of the upper ladder and fasten the lifting rope. Open the ladder to a suitable width and use it. When lifting, please Light up and down.
5. To lower the ladder, gather the two sides of the ladder closer, then unfasten the fixed rope, raise the ladder a little, make the fixed clip away from the step surface, and then slowly descend.
