General Power Tool Safety Warnings

⚠️ WARNING! When using the equipment, a few safety precautions must be observed to avoid injuries and damage. Please read the complete operating instructions and safety regulations with due care. Keep this manual in a safe place, so that the information is available at all times. If you give the equipment to any other person, hand over these operating instructions and safety regulations as well. Hangzhou GreatStar Industrial Co., Ltd cannot accept any liability for damage or accidents which arise due to a failure to follow these instructions and the safety instructions.

The term "power tool" in the warnings refers to your mains-operated (corded) power tool or battery-operated (cordless) power tool.

1) Work Area Safety

• Keep work area clean and well lit. Cluttered or dark areas invite accidents.
• Do not operate power tools in explosive atmospheres, such as in the presence of flammable liquids, gases or dust. Power tools create sparks which may ignite the dust or fumes.
• Keep children and bystanders away while operating a power tool. Distractions can cause you to lose control.

2) Electrical Safety

• Power tool plugs must match the outlet. Never modify the plug in any way. Do not use any adapter plugs with earthed (grounded) power tools. Unmodified plugs and matching outlets will reduce risk of electric shock.
• Avoid body contact with earthed or grounded surfaces, such as pipes, radiators, ranges and refrigerators. There is an increased risk of electric shock if your body is earthed or grounded.
• Do not expose power tools to rain or wet conditions. Water entering a power tool will increase the risk of electric shock.
• Do not abuse the cord. Never use the cord for carrying, pulling or unplugging the power tool. Keep cord away from heat, oil, sharp edges or moving parts. Damaged or entangled cords increase the risk of electric shock.
• When operating a power tool outdoors, use an extension cord suitable for outdoor use. Use of a cord suitable for outdoor use reduces the risk of electric shock.
• If operating a power tool in a damp location is unavoidable, use a residual current device (RCD) protected supply. Use of an RCD reduces the risk of electric shock.

3) Personal Safety

• Stay alert, watch what you are doing and use common sense when operating a power tool. Do not use a power tool while you are tired or under the influence of drugs, alcohol or medication. A moment of inattention while operating power tools may result in serious personal injury.
• Use personal protective equipment. Always wear eye protection. Protective equipment such as a dust mask, non-skid safety shoes, hard hat or hearing protection used for appropriate conditions will reduce personal injuries.
• Prevent unintentional starting. Ensure the switch is in the off-position before connecting to power source and/or battery pack, picking up or carrying the tool. Carrying power tools with your finger on the switch or energising power tools that have the switch on invites accidents.
• Remove any adjusting key or wrench before turning the power tool on. A wrench or a key left attached to a rotating part of the power tool may result in personal injury.
• Do not overreach. Keep proper footing and balance at all times. This enables better control of the power tool in unexpected situations.
• Dress properly. Do not wear loose clothing or jewellery. Keep your hair and clothing away from moving parts. Loose clothes, jewellery or long hair can be caught in moving parts.
• If devices are provided for the connection of dust extraction and collection facilities, ensure these are connected and properly used. Use of dust collection can reduce dust-related hazards.
• Do not let familiarity gained from frequent use of tools allow you to become complacent and ignore tool safety principles. A careless action can cause severe injury within a fraction of a second.

4) Power Tool Use and Care

• Do not force the power tool. Use the correct power tool for your application. The correct power tool will do the job better and safer at the rate for which it was designed.
• Do not use the power tool if the switch does not turn it on and off. Any power tool that cannot be controlled with the switch is dangerous and must be repaired.
• Disconnect the plug from the power source and/or remove the battery pack, if detachable, from the power tool before making any adjustments, changing accessories, or storing power tools. Such preventive safety measures reduce the risk of starting the power tool accidentally.
• Store idle power tools out of the reach of children and do not allow persons unfamiliar with the power tool or these instructions to operate the power tool. Power tools are dangerous in the hands of untrained users.
• Maintain power tools and accessories. Check for misalignment or binding of moving parts, breakage of parts and any other condition that may affect the power tool's operation. If damaged, have the power tool repaired before use. Many accidents are caused by poorly maintained power tools.
• Keep cutting tools sharp and clean. Properly maintained cutting tools with sharp cutting edges are less likely to bind and are easier to control.
• Use the power tool, accessories and tool bits etc. In accordance with these instructions, taking into account the working conditions and the work to be performed. Use of the power tool for operations different from those intended could result in a hazardous situation.
• Keep handles and grasping surfaces dry, clean and free from oil and grease. Slippery handles and grasping surfaces do not allow for safe handling and control of the tool in unexpected situations.

5) Service

Have your power tool serviced by a qualified repair person using only identical replacement parts. This will ensure that the safety of the power tool is maintained.

6) Battery Tool Use and Care

• Ensure the switch is in the off position before inserting battery pack. Inserting the battery pack into power tools that have the switch on invites accidents.
• Recharge only with the charger specified by the manufacturer. A charger that is suitable for one type of battery pack may create a risk of fire when used with another battery pack.
• Use power tools only with specifically designated battery packs. Use of any other battery packs may create a risk of injury and fire.
• When battery pack is not in use, keep it away from other metal objects like paper clips, coins, keys, nails, screws, or other small metal objects that can make a connection from one terminal to another. Shorting the battery terminals together may cause burns or a fire.
• Under abusive conditions, liquid may be ejected from the battery; avoid contact. If contact accidentally occurs, flush with water. If liquid contacts eyes, additionally seek medical help. Liquid ejected from the battery may cause irritation or burns.

If the cable is trapped in the pipe (it cannot dredge or be retracted), press the forward/reverse lever to "L", then set the front operation handle on the position of "F” to retract the cable. (Only use this setting when the cable is twisted, knotted or cannot be retracted in the pipe etc.)

If set the front operation handle on the position of "C", using the switch trigger, the cable stops advance or retract, no matter in forward or reverse rotation.

NOTICE: DO NOT advance or retract the cable using the switch trigger unless the cable is in a drain pipe.

6) Using the Drain Auger (Fig.9)

The drain auger can be used to clear obstructions from a variety of drains including sink, bathtub, and toilet drains.

NOTE: This product can be used to clear drain pipes with minimum diameters of 0.75 inch and maximum diameters of 2 inch.

To clear obstructions:

• When removing an obstruction from a sink or a bathtub, it may be necessary to remove the stopper or overflow cover to gain access to the drain pipe. Toilet drains can be accessed directly through the base of the bowl.
• Hold the drain auger within four inches of the drain 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 or continue advancing it 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:
• 1. Advance the cable by squeezing the switch trigger. Hold the trigger for several seconds allowing the tip of the cable to bore into the obstruction. If the cable stops rotating, release the switch trigger to avoid kinking or damaging the cable. Then slowly retract the cable from the drain pipe.
• 2. Set the front operation handle in the position of "C", squeezing 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 be sure the cable is cleaned properly as described in the section of Cleaning the Drain Auger.

In case of obstruction or booked cornering of the cable, pull front operating handle back to "R" to retract for a certain distance, and then pull the operation handle forward to "F" to advance again. Repeatedly move forward and backward the operating handle to dredge the pipe and move through the corners.
