2-1. Plastic cover

Use a screwdriver to detach the plastic cover.

When attaching the plastic cover, attach the cover in the base chain firmly.

2-2. Disassembling base chain

For riveted roller chain, use a hand grinder to remove the riveted ends of the two pins (on the same side) of the outer link to be cut.

Be careful not to overheat the chain when performing the grinding operation.

For Lambda chains, work especially slowly so as not to heat the oil-impregnated bushes.
