5. Assembly and Installation

Preparation: Ensure that all components such as retainer, shaft, axle, or bolt are clean and free from dirt or foreign objects to ensure safe and proper attachment. Also, check the dimensions of the shaft or bolt to ensure they match the size of the KL-retainer.

Tool selection: KL-retainers can be installed without special assembly tools. However, for precise and efficient work, the use of a suitable assembly tool is recommended. For example, use a universal pliers to position the retainer.

Assembly: Hold the KL-retainer between thumb and forefinger. Press the retainer into the groove of the shaft or bolt by hand. Ensure you apply even pressure to enable correct placement. If necessary, use pliers to position the retainer and press it fully into the groove.

Post-installation check: Conduct a visual inspection of the KL-retainer to ensure it is fully and securely seated in the groove. If necessary, check the connection by gently twisting or pulling to ensure everything is correctly placed.

Maintenance and adjustment: Regularly check the KL-retainers to ensure they remain securely in place and show no signs of wear or damage. If needed, the retainers can be removed and reassembled with suitable tools (see assembly).

Following these steps ensures the KL-retainers are properly and securely installed, guaranteeing reliable fixation and longevity of the fasteners.

6. Safety instructions & Standards

Safety instructions:

Always wear appropriate personal protective equipment (PPE) such as safety glasses and gloves to prevent injuries during assembly.
Ensure all components such as shafts, axles, and bolts are clean and free of dirt to allow safe fastening.
Use KL-retainers only in the designated application areas, and choose the appropriate size for your specific requirements.
Regularly inspect the KL-retainers for wear or damage and replace them as needed to ensure safety and functionality.
