Keep the workplace clean and tidy and with sufficient lighting. Chaos and darkness of the environment
are likely to cause safety accidents.
Do not operate the machine in hazardous environments that is flammable and explosive, such as
flammable and explosive liquids, gases or dust. Power tools are prone to generate sparks that can
ignite these dusts or gases.
When operating the machine, keep unrelated personnel (including children, bystanders, non-staff,
etc.) away from the work site. Distraction could easily lead to the occurrence of safety accidents.
The power tool plug should match the socket. Do not change the plug at all times. Do not connect
the adapter of the plug of grounded power tool to be used together. Not changing the plug and
matching the socket will reduce the occurrence of electric shock.
Do not place the power tools in rain or in a humid environment. Liquid entering the power tool will
increase the risk of electric shock.
Do not damage the power cord. Do not use the power cord to drag and pull the power tool. Keep the
power cord away from hot, oil, sharp edges or moving objects. Damage to the power cord or other
objects twined can increase the risk of electric shock.

When power tools are used outdoor, please use suitable outdoor special extension cord, which
might reduce risk of electric shock.
Avoid using the power tools in a humid environment. Please use the GFCI protection device, which
can reduce the risk of electric shock.
When using the power tools, keep a clear head and concentrate.
Do not use power tools in the event of fatigue or affected by medicine, alcohol or drugs. Careless
operation will lead to serious injury accidents.
Use personal protective equipment properly and always wear safety goggles. Personal protective
equipment includes dust masks, non-slip safety shoes, hard mats or thermal protection devices.
Appropriate use of the protective equipment will reduce the personal injury accidents.
Keep the body in balance and do not lose balance when operating the machine. This will help you
better control the tools in the case of accidents.
In prevention of unexpected startup, when connected to power or battery.
Please use designated charger specified by the manufacturer only. It might cause fire when one type
of charger is used for another type of battery pack.
Electric power tool can apply the designated battery packs, otherwise application of other battery
packs might cause personal injuries or fire.
When battery pack is not used, please place it away from metallic objects like paper clips, coins,
keys, nails, screws or other small metal materials, which may form connection from one end to the
other, short circuit the battery terminal and cause burning or fire.
When overused, there may be liquid flowing out of the battery. Please avoid direct body contact. If
there is accidental contact with battery drain, please rinse with water. In case of eye exposure,
please see a doctor. Battery drain might cause allergic inflammation or burns.
Before use of battery pack, please review all relevant instructions and warning labels of the (1)
charger, (2)battery pack and products that (3) need to use battery pack.
Non-detachable battery pack.
If the working hours are too short, it shall immediately stop operation; otherwise, it may cause
overheating, burning or even exploding.
In case of eye exposure to electrolyte, rinse eyes with water immediately and ask for doctor’s advice,
otherwise, it might cause blindness.
When the battery pack is not used, be sure to use the battery cover to cover the battery pack
terminal.
Do not make the battery pack short circuited
Do not make any conductor contact the terminal of the battery pack
Do not place the battery pack in the containers with iron nails, coins and other metallic objects.
Do not place the battery pack in areas with water or may be affected by rain.
Battery short circuit will cause a huge current to pass and overheat, which might result in burning or
even accidents.
Do not place the host machine and battery pack in areas above 50°(122°F).
Even if the battery pack is seriously damaged or completely depleted, do not burn it, otherwise the
battery pack will be exploded in the fire.
Be careful not to cause falling off or collide with the battery pack.
Charge the battery pack before full discharge.

Do not charge the charged battery pack. Overcharging will shorten the service life of the battery
pack.
Charge the battery pack with ambient temperature at 10°-40°(50°F-104°F), please cool down the
heated before charging.
When battery pack is not used for over six months, charge the ni-mh battery pack.
It will cause injury to fingers, hands, arms or other body parts if clothes or gloves are drawn into the
rotating parts.
It will cause electric shock or burn when contacting the motor or other electric components.
Eye injury caused by the flexible shafts, cables or flying debris.
Wear rubber gloves.
Wear protective goggles.
Make the machine close to the pipe inlet.
Do not use soft gloves or cloth to hold the rotating flexible shaft, which may cause serious injury if
twined in the flexible shaft.
Do not over-deliver the flexible shaft, excessive deliver due to blockage may cause the winding or
break off of flexible shaft and cause serious injury.
Keep the tool as close as possible to the pipe. When the tool is difficult to approach the pipe, use the
front guide tube. If the distance is too long, it may cause the winding or break off of flexible shaft.
Do not operate the machine while reversing (pressing the forward and reverse rotation button R).
Operating in the (R) state can cause damage to the flexible shaft. The button (R) is only used to exit
the flexible axis in case of blocking.
