10. Use safety equipment. Always wear eye  
protection. Safety equipment such as dust mask,  
non-skid safety shoes, hard hat, or hearing  
protection used for appropriate conditions will  
reduce personal injuries.

11. Avoid accidental starting. Ensure the switch is  
in the off-position before plugging in. Carrying  
power tools with your finger on the switch or  
plugging in power tools that have the switch on  
invites accidents.  
12. 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.  
GENERAL SAFETY RULES  
WARNING! Read all instructions. Failure to follow all  
instructions listed below may result in electric shock, fire  
and/or serious injury. The term "power tool" in all of the  
warnings listed below refers to your mains-operated  
(corded) power tool or battery-operated (cordless) power  
tool.  
SAVE THESE INSTRUCTIONS.  
13. Do not overreach. Keep proper footing and  
balance at all times. This enables better control  
of the power tool in unexpected situations.  
14. 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.  
15. If devices are provided for the connection of  
dust extraction and collection facilities,  
ensure these are connected and properly used.  
Use of these devices can reduce dust-related  
hazards.  
Work area safety  
1.  
Keep work area clean and well lit. Cluttered and  
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.  
Keep children and bystanders away while  
operating a power tool. Distractions can cause  
you to lose control.  
3.  
Electrical Safety  
4.  
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  
Power tool use and care  
16. 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.  
17. 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.

a
power tool will  
18. 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  
starting the power tool accidentally.  
19. 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.  
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.

20. Maintain power tools. Check for misalignment  
or binding of moving parts, breakage of parts  
and any other condition that may affect the  
power tools operation. If damaged, have the  
power tool repaired before use. Many accidents  
are caused by poorly maintained power tools.  
21. Keep cutting tools sharp and clean. Properly  
maintained cutting tools with sharp cutting edges  
are less likely to bind and are easier to control.  
22. Use the power tool, accessories and tool bits  
etc. in accordance with these instructions and  
in the manner intended for the particular type  
of power tool, taking into account the working  
conditions and the work to be performed. Use  
of the power tool for operations different from  
to screwdriver safety rules. If you use this power  
tool unsafely or incorrectly, you can suffer serious  
personal injury.  
1.  
Hold power tools by insulated gripping  
surfaces when performing an operation where  
the cutting tool may contact hidden wiring or  
its own cord. Contact with a "live" wire will make  
exposed metal parts of the tool "live" and shock  
the operator.  
2.  
Always be sure you have a firm footing.  
Be sure no one is below when using the tool in  
high locations.  
3.  
4.  
5.  
Hold the tool firmly.  
Keep hands away from rotating parts.  
Do not touch the bit or the workpiece  
immediately after operation; they may be  
extremely hot and could burn your skin.

a
hazardous  
Battery tool use and care  
23. 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.  
24. 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.  
SAVE THESE INSTRUCTIONS.  
WARNING:  
MISUSE or failure to follow the safety rules stated in  
this instruction manual may cause serious personal  
injury.  
ENC007-2  
25. Use power tools only with specifically  
designated battery packs. Use of any other  
battery packs may create a risk of injury and fire.  
26. 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.  
27. 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.  
IMPORTANT SAFETY  
INSTRUCTIONS  
FOR BATTERY CARTRIDGE  
1.  
Before using battery cartridge, read all  
instructions and cautionary markings on (1)  
battery charger, (2) battery, and (3) product  
using battery.

shorter, stop operating immediately. It may  
result in a risk of overheating, possible burns  
and even an explosion.  
4.  
5.  
If electrolyte gets into your eyes, rinse them  
out with clear water and seek medical  
attention right away. It may result in loss of  
your eyesight.  
SERVICE  
28. 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.  
29. Follow instruction for lubricating and  
changing accessories.  
Do not short the battery cartridge:  
(1) Do not touch the terminals with any  
conductive material.

Always hold the tool squarely against the driving  
surface. Holding it at an angle may damage the  
screw heads and cause wear on the bit. This may  
also lead to poor fastening.  
Always keep the tool firmly against the driving  
surface until the driving is over. Failure to do so  
may cause insufficient fastening of screws.  
Be careful not to drive a screw onto another screw  
already fastened.  
Do not operate the tool without screws. It will  
damage the driving surface.  
Do not apply oil or grease on the sliding surface of  
the feeder box.  
Replace when they wear down to the limit mark. Keep  
the carbon brushes clean and free to slip in the holders.  
Both carbon brushes should be replaced at the same  
time. Use only identical carbon brushes.
