NO TICE
● 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.

Step 6 Reinstall the pre-fab. module bases to the concrete platforms with the expansion
bolts securing the bases. Remount the flat washers, spring washers, and nuts on
the expansion bolts and tighten the expansion bolts in sequence using a torque
wrench.
