Using your Wera 334 SK 1.2 x 6.5 x 125mm Slotted Flat Head Screwdriver is easy. First, pick the right screw. Then, insert the screwdriver tip into the screw head. Hold the soft grip zone when you need more torque for tightening or loosening. Use the smooth hard zone for fast turning.
When using it, don't use too much force that could damage the screw or the screwdriver. Also, make sure the tip is well - seated in the screw head to avoid slipping.
For maintenance, keep it clean. After use, wipe it with a dry cloth. Store it in a dry place to prevent rust. If it gets dirty, you can use a mild cleaner, but dry it thoroughly afterward. This will keep your screwdriver in good shape for a long time.
