The stride level and box level are similar in construction. To check the adjustment of the box level, place
the box level on the Ultradex and follow the general procedures for the stride level given in steps 4-12
below.

Remove the stride level from its case, place on barrel of MTC and secure with strap. Use pencil or piece of tape
to mark its longitudinal position so that level may be returned to same position in subsequent steps.
(5)
Use tilt adjustment provided on mounting base to bring split bubble into coincidence.
(6)
With bubble in coincidence, roll stride level away from you around barrel until bullseye bubble on top is tangent
to outside of circle. See if split bubble is still in coincidence. If not, roll adjustment must be made.

Roll adjustment is made by turning opposed setscrews bearing against right-hand vial adjustment screw. Access
to rear setscrew is obtained by removing socket-head setscrew in main housing, directly opposite vial adjustment
screw. Access to front screw is gained through hole between right hand adjusting nuts. Upper adjusting nut on
right-hand adjustment screw must be loosened slightly prior to making any adjustment, access to this nut is
through slot. Adjust as follows:
(a)
If right side of split bubble went up when level was rolled away from you, loosen front setscrew and tighten
rear setscrew.
(b)
If left side of split bubble went up, loosen rear setscrew and tighten front setscrew.
