Use a properly adjusted inline lubricator or manually lubricate through the inlet.

For manual lubrication:

Disconnect the air supply.
Add 10–15 drops of No. 10 Air Tool Oil to the inlet.
Reconnect safely and run briefly to distribute the oil.

During extended operation without a lubricator, reapply oil approximately hourly.

Isolate and disconnect the air supply.
Remove the interchangeable anvil using Changing DXS® Anvils on 2236 Series Air Impact Wrenches.
Clean around the exposed grease fitting.

Reinstall the anvil and verify retention.

Important: Do not substitute a generic pump count for the specified volume; grease-gun output varies.
