Step 1 – Open crates and separate parts
Open the shipping crates and separate the parts according to the size of the unit, refer back to Figure 1, page 1.
Step 2 – Place BASE ENDS and BASE SIDES
Place the two base ends and the two base sides in their approximate relationship to each other, see Figure 2. Fasten
