       ZLS SERIES — FLOOR HEIGHT LIFT TABLES

ZLS Series Owner’s Manual

Figure 1 shows the only safe way to work under the table top of the “ZLS” Series unit. In this manual, 
we will refer you to this procedure many times. 

In the interest of safety, please follow all of these 

steps whenever you work under the table top: 

•  Remove the load from the table top.
•  Raise the table top to the full-up position.
•  Place the supplied maintenance devices in the base rails as shown in Fig. 1. This will keep the 

legs from moving, and prevent the table top from dropping suddenly.

WARNING! 

Both the maintenance devices must hold the lift table in the full-up position! A partly-

raised lift may apply too much leverage against the base frame. This can cause the 
machine to fail, and this can cause severe personal injury to a worker.

•  Lower the table a bit so the movable legs are resting against the maintenance devices. This 

will release the pressure in the hydraulic system and hold the maintenance devices in place. 
If you do not do this, pressure may remain in the hydraulic system. If this pressure is released 
suddenly, you may be hurt, or the lift may be damaged.

•  While you are working on the lift, do not let anyone else use the controls.
•  Finish working under the table top, then reverse the process to get the lift ready for operatio
•  Go through all of these steps 

every time 

you must work under the table top. Do this even if you 

will only be under the table top for a moment!
