LPL 7452 - Operation Guide; Magnification and Elevation Control; Focus Controls

RATION
1. Magnification/Elevation Control
When the carriage lock knob (6) is loose, the head will travell freely up and down along the column.
Use the elevation handle bar (20) for swift up/down. Use, Elevation Control (21) for slow lifts.
Lock the head by tightening the carriage lock screw (6) when the position of the head is deter-
mained.
2. Focus Controls
Use one of the focus controls (22) on either
sides of the bellows. A fine focus control
(1 : 5) is also provided on the right side
focus control.
3. Floor Projection
For making extra-large prints off the base-
board, "floor projection" will be possible.
To do it, the entire head/carriage/bellows
assembly will be drawn off the column,
turned round 180° and put back onto the
column again as shown. The counter-balance
springs will be hooked and fixed on the
other side of the column, an extra screw-
hole is provided in the front side of the
column for this purpose. The column top
(4) and the counter-balance spring screw
will have to be removed and replaced in
the shift process. Please refer to "mounting
the head/carriage/bellows assembly in page 4.
Note:
Put sufficient counter-weight on the base-
board when the floor projection is carried
out.
