Replacing the Knife
1. Insert the new knife into the coupler.
2. Ensure that the sharp edge of knife should face the direction of the spring plunger.
3. Push the knife into the coupler until it stops. Make certain the knife is pushed past the ball plunger
detent.
4. Tighten the clamping bolt.
5. Lightly grease the outside diameter of the coupling assembly using Eastman No. 67-26324.
6. Insert the knife along with the coupler and blade link from the top into the reciprocating housing. The
below picture shows the knife and coupler assembly installed in the upper, middle and lower knife guide
assemblies. While holding the blade link gradually insert the knife along with the coupler into the recipro
cating housing guide tube. Ensure that the back edge of knife is facing the lower knife back roller. (The
lower knife guide back roller can be seen by pressing down the spring loaded presser foot assembly).
The tip of the knife should pass through the rectangular opening in the throat plate found on upper knife
guide. Ensure that the knife is kept in the vertical position so that the knife tip passes between the guide
rollers found on the upper knife guide. Continue lowering the knife and coupler until the coupler engages
the guide tube. Now at this point the knife and coupler are fully guided as it is lowered until the upper
holes in the blade link match with the holes in lower arm.
