• Hold the spray can upright.
• Firmly hold the handpiece to prevent it slipping when spray pressure is applied.
• Spray lubricant until it expels from the handpiece head.
• If you wish to purge excessive oil from inside the handpiece, rotate the handpiece for approx 15 seconds without a file.
During the rotation, do not depress the push button, especially when using absorbent cloth to prevent oil from scattering.
