Installation
The dowel pins protruding from the ends of the platen are the platen
shafts, and are not equal in length. The platen must be installed with the
longer shaft on the right side.
1. Wipe the platen shafts clean of grease and debris.
2. Install two washers on the longer (right) platen shaft. (See Figure 36.)
3. Apply bearing lubricant to both platen shafts.
4. Make sure the two wear saddles are set flush into the corners of the
mechanism base platen seat. (See Figure 37.)
5. Apply a layer of bearing lubricant 1/4 inch high to the seat of each wear
saddle, making the layer as wide as the saddle and touching the rear
angled surface.
6. Install one platen adjust bracket onto the longer platen shaft, with the
screw at the top of the bracket.
7. Place the other bracket onto the left side mechanism base platen seat so
that the mechanism base platen seat is between the flanges of the
bracket.
8. Insert the shorter platen shaft through the left adjust bracket and through
the opening in the left side plate. Rotate the longer shaft into the opening
in the right side plate and position the adjustment brackets as shown in
Figure 36.
