Model: 22-790X - Assembling planer onto the mobile base

The installation instructions don't state whether the mobile base is
to be attached/secured to the planer unit, with screws or other means,
OR if the planer unit simply sits within the frame of the mobile
base. There are no extra screws for attaching the unit to the mobile
base.

The unit is heavy, so it may not need to be secured to the base, but I
would like to know for sure. Any help would be appreciated.

Thanks.
Sonny - finally getting around to this installation.
