Before servicing the dock leveler, read and follow the
Safety Practices on page 3, and the Operations Instruction
section on pages 16 through 18 of this User's Manual.
Be certain, before climbing into the dock leveler pit or
doing any maintenance or repair under the dock leveler,
that: 1) THE MAINTENANCE STRUT IS IN POSITION AND
PINNED, LIP LOCK IS IN PLACE AND SUPPORTING THE
LIP [see Fig. 38] and 2) the power is disconnected and
properly tagged or locked off.
Hydraulic pressure or mechanical support must be
maintained on the ramp and lip to hold them in the raised
position until the maintenance strut and lip lock are in
place. DO NOT WORK UNDER THE DOCK LEVELER
RAMP OR LIP UNLESS THE MAINTENANCE STRUT IS IN
PLACE AND PINNED, AND LIP LOCK IS IN PLACE AND
SUPPORTING THE LIP.
