INSTRUCTIONS

•  Read and follow all 

instructions, warnings, and 

maintenance schedules in 

the manual and on placards.

•  Operation and servicing of 

dock leveler is restricted to 

authorized personnel.

•  Always chock transport vehicle wheels or engage vehicle restraint 

and set parking brakes before operating dock leveler or beginning 

to load or unload.

•  Before activating dock leveler, check to make sure the transport 

vehicle is positioned squarely against dock bumpers. Ensure lip will 

avoid contact with transport vehicle frame, sides and cargo during 

dock leveler activation. If contact is likely or observed, reposition 

transport vehicle.

• 

Ensure  the  transport  vehicle  floor  supports  extended  lip  or  the 

leveler frame (lip keepers or below dock endload supports) supports 

the ramp before driving on ramp.

•  Stay clear of hinges and front and sides of moving dock leveler.

•  Never use hands or equipment to move the ramp or lip.

•  Never use damaged or malfunctioning dock leveler. Report problems 

immediately to supervisor.

•  Always store dock leveler and remove people, material, and 

equipment from ramp before vehicle leaves the dock.

•  DO NOT ENTER PIT unless dock leveler is securely supported 

and proper lockout/tagout procedures have been completed. See 

“Maintenance Precautions” in Owner’s/User’s Manual.

FAILURE TO FOLLOW THESE INSTRUCTIONS WILL RESULT 

IN DEATH OR OTHER SERIOUS INJURY.

DANGER

POWERED DOCK LEVELERS

NORMAL OPERATION

1.  Raise the platform by Pressing and holding 

the RAISE button.

2.  Hold the RAISE button until the lip is fully 

extended, then release the RAISE button. 

The platform will lower until lip is resting on 

the transport vehicle.

STORING LEVELER

1.  Press the RAISE button until the lip is 

completely folded. When the lip is folded, 

release the RAISE button. The platform will 

lower returning to the cross-traffic position.

BELOW DOCK ENDLOADING

•  (AIR POWERED ONLY)

 Press and hold 

the RAISE button until the leveler is 12” 

above dock level. Pull the below dock level 

chain until the leveler lowers the full below 

dock position. 

•  (HYDRAULIC ONLY)

 Press and hold 

the RAISE button until the leveler is fully 

raised. As the lip starts to extend, release 

the RAISE button. The leveler will lower 

to the below dock position provided the 

lip extension allows the lip to clear the lip 

keepers.

•  (HYDRAULIC WITH INFINITE LIP 

CONTROL)

 If equipped, raise the platform 

by Pressing and holding the RAISE button. 

When the lip is just above the  lip keepers, 

simultaneously Press and hold the RAISE 

button and the LIP OUT button until lip has 

extended beyond the lip keepers. Release 

both buttons.

NOTE: If equipped, Pressing E-STOP button will stop platform from lowering.
