Setting The Top-Plate Angle; Inserting The Chain - Oregon 730-120 Original Instruction Manual

Operation

5.2.3 Setting the top-plate angle

Note: Read the specifications from the chain
manufacturer to find out the recommended top-
plate angle for your chain.
1. Use the hex key (provided with the
machine) to loosen the top-plate angle
screw up to three turns.
2. Turn the grinding head to set the desired
top-plate angle (0-35°) on the top-plate angle
scale. The default top-plate angle is 30°.
3. Tighten the top-plate angle screw.
4. Press the grinding head positioning button
to move the grinding head in both
directions and make sure that the top-plate
angles are the same.

5. If the top-plate angles are not the same (for
example 26° in the right direction and 30°
in the left direction), adjust the nuts (A) a
1/2-turn at the time.
6. Repeat steps 2-5 until the top-plate angles
are the same in both directions.

5.2.4 Inserting the chain

1. Check the chain for double-links (2 left
cutters or 2 right cutters) or joint-links, and
make sure that the chain is not damaged.
Mark double-links or joint-links to make
it easier to see them when the chain is
sharpened.
2. Attach the stop clamp on a tie-strap
between a double-link or a joint-link.
