INSTRUCTIONS
1) Set up the ladder jacks
Set two ladders in position for the jacks so that when the plank is in position each of its ends will extend 1 foot beyond a jack. If using a 10-foot long plank this means setting the ladders about 8 feet apart. Check that each ladder is level and stable. Working one ladder at a time, carry up a ladder jack and, at the desired height, secure the jack properly to the rung. (Fig. 1) Make sure that both jacks are set to an equal height. Refer to the instructions that accompany the jacks for specific information.
