Operating Instructions
The WORKPRO Electric Drain Auger is designed for pipes ranging from 3/4 inches up to 2 inches in width, with a 25-foot (7.6m) cable. The olive-shaped head is ideal for navigating L, S, and U bends.

Figure 4: The flexible cable and olive-shaped head are designed for various pipe configurations.
Basic Operation Steps:
- Prepare the Area: Clear the drain opening and ensure you have a bucket or container ready to catch any debris or water.
- Insert the Cable: Manually feed the cable into the drain opening. For best results, ensure at least 4 inches of cable are extended from the drum before starting the motor.
- Select Direction: Use the Forward/Reverse Lever to select the desired rotation direction (Forward for extending the cable, Reverse for retracting).
- Engage and Feed:
- To feed the cable forward, press the Front Operating Handle forward (towards the cable exit).
- To retract the cable, pull the Front Operating Handle backward (towards the handle).
- Control Speed: Press the Variable Speed Switch Trigger to start the motor and control the cable's rotation speed. Adjust the speed as needed for different types of clogs.
- Clear the Clog: Slowly feed the cable into the drain, allowing the rotating head to break up and clear the obstruction. If the cable encounters resistance, gently work it back and forth.
- Retract the Cable: Once the clog is cleared, switch the Forward/Reverse Lever to Reverse and pull the Front Operating Handle backward to retract the cable.
- Clean Up: After use, clean the cable and the drum thoroughly.

Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Tool does not turn on. | Battery not charged or not properly inserted. | Ensure battery is fully charged and securely clicked into place. |
| Cable does not extend or retract. | Forward/Reverse Lever not engaged or Front Operating Handle not pushed/pulled. | Ensure the Forward/Reverse Lever is set to 'F' (Forward) or 'R' (Reverse) and the Front Operating Handle is correctly manipulated. |
| Cable gets stuck or tangled in the drum. | Improper operation, forcing the cable, or cable damage. | Do not force the cable. Ensure the Front Operating Handle is used correctly to feed/retract the cable. If tangled, carefully open the drum (refer to advanced maintenance if applicable) and untangle. If cable is damaged, replace it. |
| Ineffective clog removal. | Wrong cable size for pipe, severe clog, or incorrect technique. | Verify pipe diameter is within 3/4"-2" range. Try adjusting speed and gently working the cable. For very stubborn clogs, multiple passes or professional assistance may be required. |
