6.9 LEVELING PROCEDURE
1.
The highest point on the floor, noted from Section 6.1 step 6 is the point from which the base
frame will be leveled from. Raise the lift to full height and, using a four (4) foot level across
the base frames, verify again that this is the highest point.
2.
Starting at the corner closest to the highest point, check along the length of the base frame edge
with the four foot level and shim as required.
NOTE THE FIVE CRITICAL POSITIONS
THAT SHIMS MUST BE PLACED ON EACH BASE FRAME OF EACH MAIN
FRAME ASSEMBLY
. Refer to Figure 8.
3.
Continue shimming across that base frame from side to side, and front to rear.
4.
Once one frame is completely leveled, level the inside rails of the base frames to one another.
5.
Now level the remaining outside half of the last base frame by placing the level across that
unit and shimming as required.
6.
A quick check across, along and between each base frame will ensure the leveling procedure
was carried out successfully.
LEVELING EXAMPLE:
Assuming that the front right corner is the highest point level in the following order:
- Shim along side “A”
- Shim across from side “A” to side “B” (check along side “B” from front to back)
The Right Side base frame should now be leveled.
- Shim across from side “B” to side “C” (check along side “C” from front to back)
- Shim across from side “C” to side “D” (check along side “D” from front to back)
- Shim along side E & side F (locking Mechanism)
Both base frames should now be leveled from front to back and side to side.
NOTE: Base frame leveling should be performed as a reference before main leveling of the
decks. One last check before anchoring is to make sure that there is 36” between the
baseframes .
