
Mark all four mounting holes where each angle steel bracket contacts the concrete
platform.

Place a wooden block on the top of an expansion bolt, and then knock at the wooden block
using a claw hammer to avoid damaging the expansion bolt.

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 secure its position, use a chisel to
punch a pit before drilling.

Before you hammer an expansion bolt vertically into a mounting hole, clean up dust from
the inside and surrounding of the hole.

Each angle steel bracket must be secured by two mounting holes. Preferentially drill the
outer two mounting holes. If steel bars in a concrete platform block the drill bit, drill the
inner mounting holes.
