Operation - Kelley aFX-C User Manual

operaTion

Before operating the dock leveler, read and follow the
Safety Practices on page 3.
Use of dock leveler restricted to trained operators. Follow
procedures on placard posted near dock leveler.
DO NOT USE THE DOCK LEVELER IF IT LOOKS
BROKEN, OR DOES NOT SEEM TO WORK RIGHT. Tell
your supervisor it needs repair right away, or contact
your local Kelley distributor.
Before pressing button, ensure lip avoids contact with
vehicle sides and cargo. If lip does not lower to vehicle
floor, reposition vehicle.
Stay clear of leveler unless lip is supported by vehicle
floor or the leveler is stored at dock level. Visually check
that the lip is supported by the vehicle floor or the ramp
is supported by both front dock level supports before
driving or walking on the ramp. Unsupported dock
levelers can lower unexpectedly.
Before chocking wheels or engaging vehicle restraint,
dump air from air ride suspensions and set parking
brakes.
Always be certain that the vehicle wheels are chocked,
or that the vehicle is locked in place by a vehicle
restraining device and the brakes are set before loading
or unloading. Vehicles pulling away from the dock
unexpectedly can cause uncontrolled drop of the dock
leveler which can result in death or serious injury.
The maximum uncontrolled drop of a KELLEY
leveler, if above dock level, would be to dock level, and if
below dock level would be to the full below dock position.
Always return the dock leveler to its dock level (stored)
position before allowing the vehicle to leave the dock.
If the vehicle pulls away from the dock before the dock
leveler is stored, the lip will fall to its pendant position
and the ramp will drop. In addition, failure to properly
store the leveler may leave the leveler in a position below
the level of the dock floor. This condition may result
in unexpected drop of personnel or material handling
equipment and result in death or serious injury.
Failure to follow these instructions could result in death
or serious injury to operators and/or bystanders.

6004752K — aFX-C Dock Leveler — Safe
inTroDUCTion
The KELLEy aFX-C dock leveler is designed to span and
®
compensate for space and height differences between a
loading dock and freight carrier to allow safe, efficient freight
transfers.
The KELLEy aFX-C dock leveler uses a push-button
®
control to position the dock leveler. Pushing and holding
the push-button operates a fan which inflates an air bag to
raise the ramp. Releasing the push-button allows the ramp
to lower.
A mechanical linkage extends the dock leveler lip as the ramp
lowers from its full raised position, and the leveler with its lip
extended settles onto the vehicle floor forming a bridge.
After loading, pushing and holding the push-button raises
the ramp, and the extended lip lowers to its stored position.
Releasing the push-button (before the dock leveler reaches
the highest position) allows the dock leveler to lower to its
level, stored position.
With the dock leveler in its stored position, dock level support
legs support the dock leveler ramp at a position level with
the dock floor.
For below dock loads the dock level support legs can be
retracted by pulling the below dock chain, located in the
middle of the deck before the deck lowers past dock level.
