NOTES ON LEVELING FLOOR MODEL U412
For proper adjustment, maintaining accuracy, and safety to the operator, the brake must be level and
securely bolted to the floor. Do not leave the machine on the original shipping skid.
Preliminary Leveling:
1. Relieve all tension on bed nut (No. 2) and set screw (No. 27).
2. Raise the beam to its maximum height by means of eccentric levers (No. 10 & 11).
3. Using an accurate spirit level or protractor head level on the bed bar (front of bed),
shim under the legs until the bed bar is level front to rear and lengthwise, with floor bolts
tightened against the shims.
The brake may change shape slightly in transit. Therefore, it is advisable to further check the level as
follows:
1. Relieve all tension on beam nuts (No. 1), and set screw (No. 27).
2. Lower the beam onto the bed and loosen nut (No. 33) so there is 1/4” space between bottom of
pin (No. 31) and top surface of nut (No. 33).
3. Starting with screws finger tight, take up screws (No. 27) about one full turn.
4. Starting with nuts (No. 1 & 2) finger tight, take up each about 3/4 turn.
5. Looking through from the rear of the brake, the beam and bed should be in contact at the center
and showing a crack of light at each end, as in Fig. 1. If there is less light showing at one end,
loosen the rear floor bolt at that end and shim under the leg until light shows evenly at both ends.
6. The above steps should result in a level machine, but not necessarily the proper adjustment for
your work. To adjust for straight bending and uniform radius, follow the subsequent
PRELOADING ADJUSTMENTS .
