influence of drugs, alcohol, or medication. A moment of inattention while
operating power tools may result in serious personal injury.
1. Keep work area clean and well lit. Cluttered or dark areas invite accidents.
2. 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.
3. Keep children and bystanders away while operating a power tool.
Distractions can cause you to lose control.
Electrical Safety
11. Use personal protective equipment. Always wear eye protection. Protective
equipment such as dust mask, non-skid safety shoes, hard hat, or hearing
protection used for appropriate conditions will reduce personal injuries.
12. 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.
4. Power tool plugs must match the outlet. Never modify the plug in anyway.
Do not use any adapter plugs with earthed (grounded) power tools.
Unmodified plugs and matching outlets will reduce risk of electric shock.
5. Avoid body contact with earthed or grounded surfaces, such as pipes,
radiators, ranges and refrigerators. There is an increased risk o electric
shock if your body is earthed or grounded.
6. Do not expose power tools to rain or wet conditions. Water entering a
power tool will increase the risk of electric shock.
7. Do not abuse the cord. Never use the cord for carrying, pulling or
13. Remove any adjusting key or wrench before turning the tool on. A wrench or a
key left attached to a rotating part of the power tool may result in personal injury.
14. Do not overreach. Keep proper footing and balance at all times. This enables
better control of the power tool in unexpected situations.
15. Dress properly. Do not wear loose clothing or jewellery. Keep your hair,
clothing, and gloves away from moving parts. Loose clothes, jewellery or long
hair can be caught in moving parts.
16. If devices are provided for the connection of dust extraction and collection
facilities, ensure these are connected and properly used. Use of dust collection

for which it was designed.
18. Do not use tool if switch does not turn it on or off. Any power tool that

19. Disconnect the plug from the power source and/or the battery pack from
the power tool before making any adjustments, changing accessories,
or storing power tools. Such preventive safety measures reduce the risk of

21. Maintain power tools. 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.
22. Keep cutting tools sharp and clean. Properly maintained cutting tools with
sharp cutting edges are less likely to bind and are easier to control.
ADDITIONAL SAFETY RULES
23. Use the power tool, accessories and tool bits etc. in accordance with
these instructions, taking into account the working conditions and the

tool is maintained.
Always be sure to have a firm footing and hold both the handle and auxiliary
handle firmly with both hands to avoid dangers arising from high reaction torque.

VOLTAGE WARNING:
This machine comes with safety belt. When working at height, always fix the
machine well with the safety belt and ensure that no one is below.
Before connecting the machine to a power source (receptacle, outlet, etc.), be
sure the voltage supplied is the same as that specified on the nameplate of the

could result in serious hazard.
2. Maintenance of the Motor
The motor unit winding is the very “heart” of the power tool. Exercise due care to
ensure the winding does not become damaged and /or wet with oil or water.
※ The fastening torque is affected by a wide variety of factors including the
following. After fastening, always check the torque with a torque wrench.
3. Determining Impact Duration by the Type and Size of
the Bolt
Fastening torque increases over time and changes if the type or the size of the
bolt changes.
3. Inspecting and Replacing the Carbon Brushes

 The fastening torque is affected by a wide variety of factors including the following.
1. Voltage
MAINTENANCE AND INSPECTION
Voltage drop will cause a reduction in the impact times and fastening torque
2. Impact Duration
CAUTION:
Impact duration will affect impact times. Fastening torque will increase over time.

— Failure to use the correct size socket will cause a reduction in the fastening
torque.
— A worn socket (wear on the hex end or square end) will cause a reduction
in the fastening torque.
4. For Bolts of the Same Diameter

As for the bolts of the same diameter with the socket, proper fastening torque
changes over torque coefficients, including effective diameter of the bolts,
wearing angle, lead angle, average diameter and friction coefficient of
surface of the nut,

Different kinds of bolts need different fastening torque.

Impact duration changes over the length of the nut.

Fastening torque changes over the place where bolts or nuts are installed.

Manners of holding the wrench and fastening parts can influence the
fastening torque.
5. Bolts of different diameters
Fastening torque will change over diameters of bolts when the fastening torque
coefficient is the same with the bolt class.
6. Usage of Accessories
Using cardan joint and extension rod will reduce fastening torque of the impact
wrench. Extending impact duration properly can increase the fastening torque.
※Damaged cord must be replaced by a special cord purchased from authorized
service center.
※ To maintain product SAFETY and RELIABILITY, repairs, any other
maintenance or adjustment should be performed by authorized service centers,
always using original replacement parts.
