Tellyour supervisor it needs repair.Always be certain that the truck wheels are chocked orthat the truck is locked in place by a truck restrainingdevice and the brakes are set before loading or unloading.Trucks pulling away from the dock unexpectedly couldresult in death or serious injury.Keep both hands firmly on the hand lever while raisingor lowering the dock leveler. Keep other body partsclear of hand lever travel path while raising or loweringthe dock leveler. Do not use legs or feet to move or holdhand lever. Failure to follow these and other providedwarnings could result in death or serious injury.The Edge-of-Dock dock leveler is designed to span andcompensate for space and height differences between aloading dock and freight carrier to allow safe, efficient freighttransfers.The mechanical EOD leveler is spring counterbalanced.A hand lever is used to position the ramp and lip onto thevehicle bed, and to return the dock leveler to the storedposition.Pulling the hand lever back moves the ramp to the full raisedposition. Moving the lever forward extends the dock levelerlip onto the vehicle.After loading, pulling the hand lever back moves the lip offthe vehicle. The hand lever is then moved forward to placethe dock leveler back into stored position.When not in use, the hand lever is to be stored on the wallin its holder.Do not operate the dock leveler if operation causesundue physical strain or if physical impairments couldlead to undue strain in back, muscles, limbs or joints.Visually check that the lip is supported by the vehiclebed before driving or walking on the ramp.Always return the dock leveler to dock level (stored)position before allowing the vehicle to leave the dock.Read and follow all of the operating instructions for theMechanical Edge-of-Dock shown on pages 14 through15.Do not leave the dock leveler unattended in the uprightposition. Always store the dock leveler with the rampplate down, level with the dock floor. See Fig. 13.Never travel on bumper blocks or over the edges of theleveler.To avoid damage to load and dock leveler, do notactivate unit if loads will be in the way of extendedlip. If lip touches loads before resting on carrier floor,move vehicle to allow unit to return to stored position.Remove end load without placing lip on carrier floor. Donot use power equipment to force lip into vehicle or lipor linkage will be damaged.March 20176016089B — Mechanical Edge-of-Dock Levelers Entrematic Group AB 201713
