the actuating pawl shaft, be careful not to drop the actuating pawl. The spring
is under tension and could fly out.
Assembly Instructions
1. When assembling the Model 250P make sure all surfaces are free of dirt and
grit.
2.
CAUTION: Always wear safety glasses when assembling the Model
250P.
The springs to be assembled are under tension and could cause eye
injury.
3. The following directions assume the numbering head is resting with the front
side up and the frame legs toward the operator and the pawl block mill cut is
on the rear side.
4. If the actuating pawl is already assembled in the actuating arm, skip
instructions 5 through 16.
5. Cut a pin slightly shorter than the outside width of the actuating pawl and
small enough in diameter to slip through the actuating pawl and shaft holes.
6. Position the actuating pawl with the flat surface up and the legs toward the
operator. Start the pin from the left hand side through the hole in the leg and
halfway across the space between the legs.
7. Slip the actuating pawl spring (50-3-17) over the pin in such a way that the
right angle bend in the spring leg mates with the right angle surfaces between
the legs.
8. Rotate the other leg of the spring in the direction of increasing spring torque,
until it catches on the side of the pawl block opposite the flat side.
9. Push the pin completely through the spring and into the opposite leg of the
actuating pawl.
10. Make sure the pin is not longer than the width of the actuating pawl.
11. Position the actuating arm with the arm bar in a horizontal position and the
straight edges of the arm legs facing down.
12. Slide the actuating pawl in between the arm legs, with the actuating pawl
prongs pointing toward the arm bar and the actuating pawl spring down.
13. The actuating pawl must be moved in this position toward the arm bar until
the holes in the actuating pawl align with the actuating pawl shaft holes in the
arms. As the pawl is moved toward the arm bar, the spring leg, which extends
