Installation
IMPORTANT
The dowel pins protruding from the ends of the platen are called the
platen shafts, and are not equal in length. The platen must be installed
with the longer shaft on the right side.
1.
Install two washers (15) on the longer platen shaft.
2.
Apply M–3 lubricant to both platen shafts and to the mating diameters
of the platen adjustment brackets (16).
3.
Install the platen adjustment brackets (16) onto the platen shafts with the
set screws at the top of the brackets.
4.
Make sure the two wear saddles (17) are set flush into the corners of the
mechanism base platen seat (18).
5.
Apply a layer of M–3 lubricant 1/4 inch high to the seat of each wear
saddle (17), making the layer as wide as the saddle and touching the rear
angled surface.
6.
Insert the shorter platen shaft through the opening in the left side plate.
Rotate the shaft into the opening in the right side plate and position the
adjustment brackets (16) so the mechanism base platen seats are
between the flanges of the brackets.
7.
Install the forms thickness indicator plate:
a.
Slide the indicator plate (13), with the interlock switch assembly
attached, onto the platen shaft and up against the right side plate.
b. Install the washer (12) and screw (11).
c.
Connect the platen interlock switch connector (10) to the
connector in the right side plate.
8.
Apply M–3 lubricant to the two platen shafts:
a.
On the left side, between the end of the platen and the platen
adjustment bracket (16).
b. On the right end, between the two washers (15).
9.
Apply M–3 lubricant to the nylon bearings (19) in the two spring links,
slide the spring links onto the two platen shafts, and connect the two
springs to the spring hooks in the side plates.
10. Install the forms thickness lever (9) onto the right side platen shaft and
adjust the platen angle (page 4–12).
