Location 

Locate lift to allow plenty of working room on all 
sides.  In front of the bay, allow room for 
workbenches, aisles, lubrication equipment or 
other obstructions. Observe the recommended 
minimums, 

Fig 2

. Check overhead clearances 

as ordinarily 12 feet is ample for automobiles. 
The power unit may be installed on the nearest 

wall or under work bench.  The power unit 
should be located out of the working area 
around the lift and vehicle, but close enough to 
allow good visibility while operating the lift.  Mark 
cut outs and centerlines on existing floor or 
excavation site. 

Fig 2 – Block Out and Location 

Excavation 

Refer to 

Fig 2

 for dimensions, to saw cut an 

existing facility floor or to block out a new 
construction floor.  Also, it will be necessary 
to break out a trench 6"-8" wide by 12" deep 
to run the PVC chase. It is recommended to 
mark the path and area before cutting. For 
excavation dimensions see 

Figure 3

.   All 

depths are measured from the finished floor 
level.  Failure to comply will void the 
warranty.  Hydraulic and air lines from the lift 
should be recessed under the slab in a 2” 
sch. 40 PVC chase.
