Using your Wera 334 Slotted Flat Head Screwdriver is easy. First, pick the right size for the screw you're working with. The color - coding on the screwdriver will help you find the right one quickly. Insert the tip of the screwdriver into the slot of the screw. Hold the soft grip zone firmly for better control and more torque when turning. For faster turning, you can use the smooth hard zones. When you're done, clean the screwdriver with a dry cloth to keep it in good condition. Store it in a dry place to prevent rusting. Avoid using it on screws that are too large or too small for the size of the screwdriver, as this can damage both the screwdriver and the screw.
