Quick Guide – Extra Long Hex Key Set (SR-1298)

Instructions

1. Select the correct key size using the color coding. The key must fit snugly into the screw head without play.

Care & Storage

Remove dirt, oil, and moisture with a soft cloth after use.
Store the set in a dry place using the supplied holder to help prevent corrosion and damage.

Disposal

Dispose of the product according to local regulations at the end of its service life.
