Warnings  
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.  
WARNING Read all safety warnings and all  
instructions. Failure to follow the warnings and  
instructions may result in electric shock, fire and/or  
serious injury.  
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.  
13. 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.  
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.  
Save all warnings and  
instructions for future reference.  
The term "power tool" in the warnings refers to your  
mains-operated (corded) power tool or battery-operated  
(cordless) power tool.  
Work area safety  
1.  
2.  
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.  
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  
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 can reduce dust-related  
hazards.

Power tool use and care  
Service  
17. 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.  
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.  
18. 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.  
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  
starting the power tool accidentally.  
20. 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.  
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.  
23. 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.  
29. Follow instruction for lubricating and  
changing accessories.  
30. Keep handles dry, clean and free from oil and  
grease.

SAFETY WARNINGS  
1.  
2.  
3.  
Wear ear protectors. Exposure to noise can  
cause hearing loss.  
Use auxiliary handle(s), if supplied with the  
tool. Loss of control can cause personal injury.  
Hold power tool by insulated gripping  
surfaces, when performing an operation  
where the cutting accessory may contact  
hidden wiring. Cutting accessory contacting a  
"live" wire may make exposed metal parts of the  
power tool "live" and could give the operator an  
electric shock.  
4.  
Wear a hard hat (safety helmet), safety glasses  
and/or face shield. Ordinary eye or sun  
glasses are NOT safety glasses. It is also  
highly recommended that you wear a dust  
mask and thickly padded gloves.  
5.  
6.  
Be sure the bit is secured in place before  
operation.  
Under normal operation, the tool is designed  
to produce vibration. The screws can come  
loose easily, causing a breakdown or accident.  
Check tightness of screws carefully before  
operation.  
Battery tool use and care  
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.  
7.  
In cold weather or when the tool has not been  
used for a long time, let the tool warm up for a  
while by operating it under no load. This will  
loosen up the lubrication. Without proper  
warm-up, hammering operation is difficult.  
Always be sure you have a firm footing.  
Be sure no one is below when using the tool in  
high locations.  
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.  
8.  
9.  
Hold the tool firmly with both hands.  
10. Keep hands away from moving parts.  
11. Do not leave the tool running. Operate the tool  
only when hand-held.  
12. Do not point the tool at any one in the area  
when operating. The bit could fly out and  
injure someone seriously.  
13. Do not touch the bit or parts close to the bit  
immediately after operation; they may be  
extremely hot and could burn your skin.

Do not force the tool. Light pressure gives best results.  
Keep the tool in position and prevent it from slipping  
away from the hole.  
Do not apply more pressure when the hole becomes  
clogged with chips or particles. Instead, run the tool at  
an idle, then remove the bit partially from the hole. By  
repeating this several times, the hole will be cleaned out  
and normal drilling may be resumed.  
007345  
The depth gauge is convenient for drilling holes of  
uniform depth. Loosen the side grip and insert the depth  
gauge into the hole in the side grip. Adjust the depth  
gauge to the desired depth and tighten the side grip.  
CAUTION:  
There is a tremendous and sudden twisting force  
exerted on the tool/bit at the time of hole  
break-through, when the hole becomes clogged  
with chips and particles, or when striking  
reinforcing rods embedded in the concrete. Always  
use the side grip (auxiliary handle) and firmly hold  
the tool by both side grip and switch handle during  
operations. Failure to do so may result in the loss  
of control of the tool and potentially severe injury.  
NOTE:  
The depth gauge cannot be used at the position  
where the depth gauge strikes against the gear  
housing.

CAUTION:  
Never use "rotation with hammering" when the drill  
chuck assembly is installed on the tool. The drill  
chuck assembly may be damaged. Also, the drill  
chuck will come off when reversing the tool.  
Pressing excessively on the tool will not speed up  
the drilling. In fact, this excessive pressure will only  
serve to damage the tip of your bit, decrease the  
tool performance and shorten the service life of the  
tool.  
002449  
After drilling the hole, use the blow-out bulb to clean the  
dust out of the hole.  
Chipping/Scaling/Demolition  
There is a tremendous twisting force exerted on  
the tool/bit at the time of hole breakthrough. Hold  
the tool firmly and exert care when the bit begins to  
break through the workpiece.  
A stuck bit can be removed simply by setting the  
reversing switch to reverse rotation in order to back  
out. However, the tool may back out abruptly if you  
do not hold it firmly.  
007347  
Always secure small workpieces in a vise or similar  
hold-down device.  
Set the action mode changing knob to the  
symbol.  
Hold the tool firmly with both hands. Turn the tool on and  
apply slight pressure on the tool so that the tool will not  
bounce around, uncontrolled. Pressing very hard on the  
tool will not increase the efficiency.
