Basic Assembly Principles
Here are a few basic tips that will aid in the assembly process .
By using these principles, you can simplify each process and save
yourself extra time and effort.
1. To make the assembly process go faster, gather the pieces you need
for each step and thoroughly read the assembly instructions for that
step prior to starting assembly for the step.
2. When attaching two pieces, gently lift and look through the bolt holes
to help guide the bolt through the holes.
3. As a general rule, and for all bolts and nuts, turn bolts or nuts toward
the right to tighten and left to loosen. Or you can remember the
mnemonic: “Righty tighty, lefty loosey.”
