installation troubleshooting
The following procedures apply after the leveler is level in
the pit.
PROBLEM
POSSIBLE CAUSE
1)Leveler will not fit properly in pit.
a) Pit is out of square with the sides.
a1)Align the sides parallel and equally
spaced with the rear frame angle
touching the rear curb angle in one
place. Fill the gap between the rear
curb angle and rear frame angle using
shims in weld noted in Fig. 10. See
Fig 20.
b) One side and rear angle is out of
square.
b) Align the leveler with the two square
edges. The gap on the sides should
be even in the most narrow section
(1/2" Max. per side). See Fig. 21.
c) Pit floor irregular in rear.
c) If large deformations exist in the
concrete work, attempt to flatten
out the rough surface using a chisel
or grinder to take out the large
obstructions. The rear leveling legs
can be installed on out of plane
surfaces up to 1/8" at each leg. See
Fig. 22.
d)Pit is too deep.
d) Weld 4" x 4" shims to the bottom of
the adjustable legs.
