5) Once the driver side leg is square and plumb in all directions, drill the holes in the concrete and
use four (4) of the supplied 5/8” lag bolts to secure the driver side foot plate to the floor.

Note: Remember to verify where any underground heat or utilities run so you can be sure to not
drill into them with the hammer drill when making the lag holes.
Note: Do not hammer the lag bolts all the way down at this time, leave room to raise the foot plate
later if necessary.
