13. Runway Leveling:
A. Use an engineer's automatic level (transit). Locate the
Level at a convenient location in the shop that allows an
unobstructed view of all four corners of the lift's runways.
Follow the Level manufacturer's instructions for proper setup.
Be sure it is adjusted level in all directions. Readjust level if it
or tripod is bumped or disturbed.
B. Make sure yoke tubes rest on column base plate.
C. First place the Level target at the highest corner of the lift.
Place it on the runway center line within 6" (152mm) of yoke
tube, whichever one is located over highest point. This will
be referred to as target "A" position. Beginning with target
"A" position, Fig. 18a, sight the Level to the target and mark
the number or the graduation on the inch scale of the target
that aligns to the crosshairs of the Level, Fig. 18b.

Note: Use a pencil, marking pen or attach a paper clip on to
the target scale at the crosshair reference.
D. Next, move the target and place it on the runway at point "B",
Fig. 18a. Rotate the Level and focus on the target scale. Adjust
the column at "B" using shims under base plate, Figs. 17 and
18, until the cross-hairs of Level align to reference mark on the
target scale. Repeat for points C and D.
