Assembling a step ladder
Step 2
Place the step ladder in the middle outside the outward opening door of the pre-fab. module,
and mark mounting holes on the concrete pad for the step ladder.
Step 3
Drill mounting holes using a hammer drill.
When you drill a hole using a hammer drill, keep the drill bit perpendicular to the ground and hold
the drill stock firmly with both hands to prevent irregular drilling and damage to the ground.
If the ground is too hard and smooth for the drill bit to fix its position, use a chisel to punch a pit
before drilling.
Step 4
Rotate nuts onto expansion sleeves to prevent the expansion sleeves from fluttering.
Step 5
Knock the expansion bolts vertically into mounting holes until the flat washers are flush with
the floor.
Step 6
Remove the nuts, spring washers, and flat washers.
