5. Vzdrževanje
Proper maintenance ensures the longevity and optimal performance of your KNIPEX pliers:
- Čiščenje: After each use, wipe the pliers clean with a dry cloth to remove dirt, grease, or debris. For stubborn grime, use a mild solvent and ensure the tool is thoroughly dried afterward.
- Mazanje: Občasno nanesite tanko plast strojnega olja na vrtljive točke in nastavitveni mehanizem, da zagotovite nemoteno delovanje in preprečite rjavenje.
- Shranjevanje: Klešče shranjujte v suhem okolju, da preprečite korozijo. Izogibajte se shranjevanju v ...amp ali vlažnih pogojih.
- Pregled: Regularly inspect the gripping teeth for wear or damage. While the teeth are specially hardened, extreme use can cause wear over time.
6. Odpravljanje težav
Tukaj so rešitve za pogoste težave, na katere lahko naletite:
- Pliers feel stiff or difficult to adjust:
Clean the pivot points and adjustment mechanism thoroughly. Apply a small amount of lubricating oil to these areas and work the pliers open and closed several times to distribute the lubricant.
- Grip is slipping on the workpiece:
Ensure the pliers are correctly adjusted to the workpiece size. The self-locking mechanism requires proper engagement. Check the gripping teeth for excessive wear or damage. If teeth are severely worn, the pliers may need replacement.
- Pojav rje na kovinskih delih:
Clean any rust spots with a fine wire brush or steel wool, then apply a rust-inhibiting oil. Ensure the pliers are stored in a dry environment to prevent future rust.
