Opening a chain:
- Loosen the knurled nut (a).
- Turn the breech (b) to position 1. Place the chain in the comb (c), using a finger to hold the link in position.
- By tightening the knurled nut (a), clamp the breech (b) firmly against the chain. The link is now secured in the comb (c).
- Rotate the spindle (d) clockwise until it touches the pin. After contact is made turn the spindle (d) approx. 4 and a half revolution for Super-Narrow-Chains (6.65-7,1mm), or approx. 5 revolutions for all other chains (7.2mm-7.5mm).
- Turn the spindle (d) back, unscrew the knurled nut (a) and remove the chain from the tool.
- Bend the link slightly and pull the chain apart.
Connecting and riveting a chain:
- Grease the chain ends and snap them together.
- Turn the breech (b) to position 2 for Super-Narrow-Chains (6.65-7,1mm), or to position 3 for all other chains (7.2-7.5mm).
- Place the link to be connected in the comb (c) with the pin through the link on the spindle side. Using a finger, hold the link in the comb.
- Turn the spindle (d) lightly against the pin, so that the chain sits securely in the comb (c).
- By tightening the knurled nut (a), clamp the breech (b) against the chain.
- By turning the spindle (d), push the pin through the pin hole until it touches the breech (b), and then turn it approx. a further 1/2 revolution. (You may have to use some force).
- Turn the spindle (d) back and unscrew the knurled nut (a).
- The pin heads are marked after being riveted. Chains should never be riveted more than once at the same point.
