Each base must be secured by four mounting holes. Preferentially drill the outer four
mounting holes. If steel bars in the concrete platform block the drill bit, drill the inner
mounting holes.
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.
1.
Drill mounting holes using a hammer drill.
2.
Rotate nuts onto expansion sleeves to prevent the expansion sleeves from fluttering.
3.
Knock the expansion bolts vertically into mounting holes until the flat washers are flush
with the floor.
4.
Remove the nuts, spring washers, and flat washers.
