The McGuire Hydraulic dock Leveler is designed for both structural integrity in operation and safety features for the protection of dock personnel.

6 Its function is to provide a safe and durable bridge between the building and the trailer. This bridge allows the safe transportation of material handling devices ( fork truck, pallet jack, hand truck) and workers for the purpose of loading and unloading the trailer. All McGuire Hydraulic levelers are equipped with a velocity fuse "Fail-Safe" system which automati- cally halts all motion of the platform, within 1 " to 3", if a truck prematurely departs with a load on the platform. Other safety features include full-range toe guards that are safety marked, a built-in service leg support and an automatic night lock feature to aid in the prevention of possible break-in attempts through the dock area. The Leveler is push button operated from a wall mount control panel and is fully electro- Hydraulic operated. Models can be equipped with an Emergency Stop button which halts all movement of the Leveler at any point during the cycle.

7 A selector switch on the control panel allows automatic posi- tiong for below dock end load situations. The unit is powered by a 1 horsepower single or polyphase electric motor with manifold block and a reservoir that is directly coupled to the motor via the manifold block. The main lift cylinder raises and lowers the platform. The lip cylinder extends, supports and retracts the lip. Flexible hosing connects both cylinders to the power unit. Electrical leads from motor/pump and integral control switches are factory wired, ready to hook up to leads in the junction box at the rear of the pit. The control panel is wired to work in conjunction with the motor/pump. Connections between terminals in the control panel and the pit junction box are not furnished by McGuire . This must be done prior to installing this Hydraulic Leveler . Connections between terminals in the control panel and the main power line are also not furnished by McGuire .

8 SAFETY PRACTICES. 1. Do not operate this equipment while under the influence of drugs or alcohol. 2. Do not stand in the driveway between the Leveler and a moving truck. 3. Be sure that the trailer wheels are chocked or restraint device is positioned. 4. Do not use the Leveler if appears to be broken or operating improperly. 5.

A licensed electrician can now connect the control panel to the main power lead in and pull the proper leads through conduit and into the junction box at the rear of the pit. Refer to the proper wiring diagrams (pages 8-11 ) for proper connection. Factory recommendation is for motor leads to extend from junction box for temporary power source. Installation of Leveler and Bumpers 5. Move the Leveler with a fork truck using the built-in fork slots in the front base frame. Position the Leveler so that the rear frame is approximately 36" from the rear of the pit. 6. A licensed electrician can now connect the temporary extended motor leads from the junction box to leads in the rubber covered cable from the Leveler motor.
