What needs to be done to securely fix a sliding ladder? Press the foot of the ladder firmly onto a solid, even surface. Set the ladder so that the front section is above the other. The rear section must face the wall or the support surface. Place the foot of the ladder at a horizontal distance from its fulcrum equal to 1/4 of the effective length of the ladder.
Stand on the ground to raise and lower the ladder. Make sure that the locking hooks are in place before climbing up the ladder. If the work surface is raised, make sure the ladder is at least 1 meter (3 feet) above the surface to be reached. Attach the top of the ladder to the fulcrums. Be careful when climbing or descending the ladder to prevent the ladder from tipping over or the base to slip.
