DO NOT use the maintenance prop to support the
raised platform until the maintenance prop has
been properly shimmed and welded. The shims
must be welded to each other, the leveler frame,
and to the front pit curb steel. Failure to do this
may result in serious personal injury or death.
16. All EH models:
a. Install shims under maintenance prop (D)
where prop attaches to leveler frame. Make
sure prop is solidly shimmed.
b. Using the appropriate lifting device, attached
to the platform lifting lugs, slowly raise the
dock to the fully open position.

necessary. Slowly raise platform again. If platform
