Operating Precautions

■ Do not mix with incompatible greases.
■ Keep away from open flames and high-temperature surfaces.
■ Wear protective gloves and goggles during application.
■ In case of skin or eye contact, rinse immediately with plenty of water.
■ Store in a cool, dry place, away from direct sunlight.
■ Dispose of used grease according to local regulations.

How To Use

■ Clean the equipment – Ensure gears, joints, and bearings are free from old grease and contaminants.
■ Apply grease – Use manually or via automatic lubrication systems, ensuring even coverage on all contact surfaces.
■ Use appropriate amount – Apply enough to form a protective film; avoid over-application to prevent leakage or overheating.
■ Check regularly – Replenish grease as needed based on operating conditions.
