RECOMMENDED FLOOR AREA

The lift table’s recommended ﬂoor area, shown in Figure 3, identiﬁes the “Danger Zone” and the “Operating Zone”. The Danger Zone is the area

inside the base frame and under the platform structure. The recommended Operating Zone is a distance of 39 inches (1 meter) extending beyond

the danger zone on all sides.

DANGER

A falling lift table can cause SEVERE PERSONAL INJURY or DEATH. NEVER go under the platform until

the load is removed and the scissors mechanism is secured in the raised position with the maintenance

FUNCTIONAL DESCRIPTION

The OPTIMUS LK series hydraulic scissors lift tables provide a convenient solution to a wide variety of material handling applications. These

electro-hydraulic lift tables are designed and manufactured to increase productivity and to reduce worker strain. By lifting and accurately

positioning the load, OPTIMUS lifts eliminate unproductive lifting and stretching that ultimately leads to worker fatigue, injuries and product damage.

They are well suited for handling a wide variety of products including work in progress, containers, bins, tools and dies.

Depressing the UP control actuates the hydraulic power unit and directs hydraulic ﬂuid to the piston side of the hydraulic cylinder(s). The cylinder

rod(s) extend and opens the scissors mechanism which in turn raises the platform. Lowering is achieved by depressing the “DOWN” control

actuating a solenoid valve at the hydraulic power unit. Opening the valve allows hydraulic ﬂuid to ﬂow out of the cylinder and return to the reservoir.

A pressure compensated ﬂow control valve within the power unit controls the lowering speed.

MAINTENANCE BAR OPERATING INSTRUCTIONS

To Engage The Maintenance Bars:

1. Remove all load from the platform and raise the lift table to its fully-raised position.

2. Move to the roller end of the lift. As detailed in Figure 4, rotate each maintenance bar approximately 90° until the bar contacts the roller

channel. Ensure both bars are positioned correctly.

3. Lower the lift by depressing the DOWN button or pedal. The lift will lower slightly until the scissors rollers contact the maintenance bars.

Release the DOWN button or pedal. ALWAYS check the position of both maintenance bars before going under the platform or servicing the

lift.

Figure 5 Maintenance Bar Operation

To Disengage The Maintenance Bars:

5. Depress the UP button or pedal to raise the platform to its fully-raised position. When the lift is fully raised, release the UP button or pedal.

6. Move to the roller end of the lift and rotate each maintenance bar approximately 90° to its stored position. As shown in Figure 5, ENSURE

both bars are in their stored position.
