10. Using TAIL/AXLE CONTROL LEVER , pull
undercarriage forward approximately 30". This

When using dock levelers, the semitrailer must
be kept level at all times. Do not lower the parking
stands. Loads being placed on the semitrailer
must be kept centered on the semitrailer. An
unlevel semitrailer may allow a load to slide,
causing injury or death to anyone near the load!
1. Do not operate dock levelers with insufficient
space on both sides of the semitrailer.
Semitrailer will lean toward the side with the
shortest cylinder. Persons or equipment can
be crushed between semitrailer side and rigid
objects.
2. Tractor park brakes must be set when using
dock levelers.
Be sure to check that the dock levelers are fully
retracted before moving the semitrailer. Failure to
retract the dock levelers before operating can
cause severe damage to the semitrailer.
DOWN/LOAD In this position, the undercarriage
slides forward to allow engaging of
dock level.
CENTER This is the neutral position.
UP/ROAD In this position, in conjunction with dock
level arm engaged, slide undercarriage
rearward lifting approach plate to dock
height.
ENGAGE
(IN) In this position, the dock level arm lifts
the approach plate to dock height.
DISENGAGE
(OUT) This is the neutral position for the dock
level arm.
When using the dock level, make sure the dock
level arm is supporting the hydraulic tail before
pulling away from the dock. Failure to do so may
result in damage to the trailer or severe personal
injury.
