  Check the platform and fl ipover for cracks, holes, and bends on the 
load-carrying surface and side plates. Also, make sure torsion bars, 
coil springs and fasteners are in place and undamaged.
  Make sure platform and fl ipover load-carrying surfaces are clean (no 
oil, debris, or corrosion).
Use the operation instructions in this manual to operate the Liftgate 
through one cycle without a load on the platform. RAISE the platform 
to vehicle bed height. Lower the platform to ground level.
  When the Liftgate is moving, listen for unusual noises and look for jerk-
ing motion or uneven movement on either side of the platform.
If service or repairs are not required (or if completed), stow the Lift-
gate.
  With the platform at ve-
hicle bed height and no 
load on platform, outboard 
edge of platform must 
be higher than extension 
plate as shown in the 
YES illustration. If the 
platform is tilted up like 
the YES illustration, you 
can operate Liftgate. If 
platform is level at bed 
height like the NO illus-
tration, do not operate 
the Liftgate. (See NOTE 
at beginning of the DAIL
Y 
OPERATION CHECKS.)
