Do not expose power tools to rain or wet  
conditions. Water entering 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.  
Power tool use and care  
a
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.  
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.  
8.  
9.  
If operating a power tool in a damp location is  
unavoidable, use  
a
ground fault circuit  
interrupter (GFCI) protected supply. Use of an  
GFCI reduces the risk of electric shock.  
Personal safety  
10. 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  
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.  
medication.  
A
moment of inattention while  
operating power tools may result in serious  
personal injury.  
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.  
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.  
Service  
24. 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.  
25. Follow instruction for lubricating and  
changing accessories.  
26. Keep handles dry, clean and free from oil and  
grease.

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 or its own cord. Cutting accessory  
contacting a "live" wire may make exposed metal  
parts of the power tool "live" and could give the  
operator an electric shock.  
CAUTION:  
Always be sure that the tool is switched off and  
unplugged before adjusting or checking function on  
the tool.

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.  
CAUTION:  
Before plugging in the tool, always check to see  
that the switch trigger actuates properly and  
returns to the "OFF" position when released.  
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

This tool employs an action mode changing knob. Select  
one of the two modes suitable for your work needs by  
using this knob.  
CAUTION:  
Always use the side grip to ensure operating  
safety.  
For rotation only, turn the knob so that the arrow on the  
knob points toward the symbol on the tool body.  
For rotation with hammering, turn the knob so that the  
arrow on the knob points toward the symbol on the tool  
body.  
Install the side grip so that the teeth on the grip fit in  
between the protrusions on the tool barrel. Then tighten  
the grip by turning clockwise at the desired position. It  
may be swung 360° so as to be secured at any position.  
Bit grease  
Coat the bit shank head beforehand with a small amount  
CAUTION:  
of bit grease (about 0.5 - 1 g).  
This chuck lubrication assures smooth action and longer  
service life.  
Always set the knob fully to your desired mode  
symbol. If you operate the tool with the knob  
positioned halfway between the mode symbols, the  
tool may be damaged.  
Use the knob after the tool comes to a complete  
stop.

Torque limiter  
1
The torque limiter will actuate when a certain torque  
level is reached. The motor will disengage from the  
output shaft. When this happens, the bit will stop turning.  
CAUTION:  
As soon as the torque limiter actuates, switch off  
the tool immediately. This will help prevent  
premature wear of the tool.  
Bits such as hole saw, which tend to pintch or  
catch easily in the hole, are not appropriate for this  
tool. This is because they will cause the torque  
limiter to actuate too frequently.

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.

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.  
007965  
NOTE:  
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.  
Eccentricity in the bit rotation may occur while operating  
the tool with no load. The tool automatically centers itself  
during operation. This does not affect the drilling  
precision.

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.
