Using the Drain Auger
The drain auger can clear obstructions from various drains, including sink, bathtub, and toilet drains. It can also be used to clear drain pipes with a minimum diameter of 0.75 inches and a maximum diameter of 2 inches.
To Clean Obstruction
NOTE: When removing an obstruction from a sink or a bathtub, it maybe necessary to remove the stopper or
overflow cover to gain access to the drainpipe. Toilet drains can be accessed directly through the base of the
bowl.
Hold the drain auger within four inches of the drains or overflow, and manually feed the cable into the drain
pipe.
NOTE: Advance the cable slowly at first. Advancing it too rapidly can result in twisting or binding.
After feeding about six inches of cable into the drain, you may begin advancing the cable using the switch trigger and operation switch or manually.
The cable should advance freely through the drain pipe until it contacts the obstruction or is caught in a P-trap.
If the cable is caught in a P-trap, additional force or increased trigger pressure should be enough to advance
it past the bend in the pipe.
If the cable has contacted an obstruction, there are two ways to remove it.
- Advance the cable by squeezing the switch trigger while holding the operation switch on the front handle. Hold the switch trigger for several seconds, allowing the cable tip to bore into the obstruction. If the cable stops rotating, release the switch trigger to avoid kinking or damaging it. Then, slowly retract the cable from the drain pipe.
- When you release the operation switch on the front handle and squeeze the switch trigger, the cable will rotate but not advance. Hold the switch trigger for several seconds, allowing the obstruction to wrap around the cable. If the cable stops rotating, release the switch trigger to avoid kinking or damaging the cable, then slowly retract the cable and pull the obstruction through the drain.
Once the obstruction is cleared, attempt to flush your toilet or run water through your drain to confirm that the water is flowing freely.
Meanwhile, please ensure the cable is appropriately cleared as described in the Cleaning the Drain Auger section.
In case of obstruction or blocked cornering of the cable, to retract the cable for a certain distance, then advance the cable again, repeatedly move the cable forward and backward to dredge the pipe and move through the corners.
NOTE: Pipe blockage situations vary. When using the cable, it is necessary to lightly depress the switch trigger (low speed) to observe its situation closely. If it is distorted or blocked, stop the machine immediately and then perform different operations according to the actual situation.
If the pipe can not be dredged, please ask a professional for help. DO NOT force the operation and cause unnecessary trouble.
CAUTION:
DO NOT force the cable delivery; otherwise, it will be twisted, knotted, or broken and cause serious injury.
DO NOT advance or retract the cable using the switch trigger unless it is in a drain pipe. When removing the cable from a drain, remove it slowly to avoid “Splashback!”
CAUTION: Do not advance or retract the cable using the switch trigger unless the cable is in the drain pipe.
Cleaning the Drain Auger
The drain auger should be cleaned after each use to prevent contamination and residue buildup.
To clean the cable:
- Remove the battery pack from the tool.
- Pull the cable out from the tool using a clean cloth and warm, soapy water, cleaning it as it advances. Continue to do this until the cable has been fully advanced and thoroughly cleaned.
- Pull the cable back into the tool using a clean, dry cloth, drying it as it retracts. Continue to do this until the cable has been fully retracted.
Maintaining the Electric Drain Auger
WARNING! When servicing, use only identical replacement parts. Using any other parts could create a hazard or cause product damage.
General Maintenance
Avoid using solvents when cleaning plastic parts. Most parts are susceptible to damage from various commercial solvents and may be damaged by their use. Use clean cloths to remove dirt, dust, oil, grease, etc.
CAUTION: Always be sure that the battery pack is removed from the tool when replacing the cable.
