GENERAL SAFETY RULES
WARNING
Read all safety warnings and all instructions. Failure to follow all warnings and instructions may
result in electric shock, fire and/or serious injury.
Save all warnings and instructions for future reference
The term “power tool” in the warnings refer to your mains operated (corded) power tool or battery
operated (cordless) power tool.
1) Work area
a)Keep work area clean and well lit. Cluttered and dark areas invite accidents.
b) 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.
c) Keep children and bystanders away while operating a power tool. Distractions can cause you
to lose control.
2) Electrical safety
a) 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.
b) 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.
c) Do not expose power tools to rain or wet conditions. Water entering a power tool will increase
the risk of electric shock.
d) 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.
e) 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.
f) If operating a power tools in a damp location is unavoidable, use a residual current device
(RCD) protected supply. Use of an RCD reduces the risk of electric shock.

3) Personal safety
a) 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
medication. A moment of inattention while operating power tools may result in serious personal
injury.
b) 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.
c) 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.
d) 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.
e) Do not overreach. Keep proper footing and balance at all times. This enables better control of
the power tool in unexpected situations.
f) 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.
g) 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 ha2ards.
4) Power tool use and care
a) 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.
b) 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.
c) Disconnect the plug from the power source before making any adjustments, changing
accessories, or storing power tools. Such preventive safety measures reduce the risk of starting the
power tool accidentally.
d) 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.
e) 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.
f) Keep cutting tools sharp and clean. Properly maintained cutting tools with sharp cutting edges are
less likely to bind and are easier to control;

g) 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
intended could result in a hazardous situation.
5) Service
a) 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.

Use the dust cup by attaching to the drill bit as shown in Fig.3
When using a bit which has big diameter, enlarge the center hole of the dist cup with this rotary
hammer.
CAUTION
{The dust cup are for exclusive use of concrete drilling work. Do not use them for
wood or metal drilling work.
{Dump particles after every two or three holes when drilling.

6. Selecting the driver bit
Screw heads or bits will be damages unless a bit appropriate for the screw diameter is employed
to drive in the screws.
7. Confirm the direction of bit rotation (Fig.4)
The bit rotates clockwise (viewed from the rear side) by pushing the R-side of the stir block. The L-side
of the stir block is pushed to turn the bit counterclockwise.
HOW TO USE
CAUTION:
To prevent accidents, make sure to turn the switch off and disconnect the plug from the receptacle when
the drill bits and other various parts are installed or removed. The power switch should also be turned off
during a work break and after work.
1. Switch operation
The rotation speed of the drill bit can be controlled steplessly by varying the amount that the trigger
switch is pilled. Speed is low when the trigger switch is pulled slightly and increases as the switch is
pulled more. Continuous operation may be attained by pulling the trigger switch and depressing the
stopper. To turn the switch OFF, pull the trigger switch again to disengage the stopper, and release the
trigger switch to its original position.
However, the switch trigger can only be pulled in halfway during reverse and rotates at half the speed of
forward operation.
The switch stopper is unusable during reverse.

(1) Attach the drill chuck to the drill chuck shank.
(2) The part of the SDS-plus shank is the same as the drill bit. Therefore, refer to the item of “Mounting
the drill bit” for attaching it.
CAUTION:
{Application of force more than necessary will not only expedite the work, but will deteriorate the tip
edge of the drill bit and reduce the service life of the rotary hammer in addition.
{Drill bits may snap off while withdrawing the rotary hammer from the drilled hole. For withdrawing, it
is important to use a pushing motion.

{Do not attempt to drill anchor holes or holes in concrete with the machine set in the rotation only
function.
{Do not attempt to use the rotary hammer in the rotation and hammering function with the drill chuck
and drill chuck shank attached. This would seriously shorten the service life of every component of the
machine.
4. When driving machine screws (Fig.9)
First, insert the bit into the socket in the end of drill chuck shank.
Next, mount drill chuck shank on the main unit using procedures described in 4(1), (2), (3), put the tip
of the bit in the slots in the head of the screw, grasp the main unit and tighten the screw.
CAUTION:
{Exercise care not to excessively prolong driving time, otherwise, the screws may be damaged by
excessive force.
{Apply the rotary hammer perpendicularly to the screw head when driving the screw; otherwise, the
screw head or bit will be damaged. Or driving force will not be fully transferred to the screw.
{Do not attempt to use the rotary hammer in the rotation and hammering function with the drill chuck
shank and bit attached.
5. When driving wood screws (Fig.9)
(1) Selecting a suitable driver bit
Employ cross-recessed screws, if possible, since the driver bit easily slips off the heads of slotted-head
screws.
(2) Driving in wood screws
{Prior to driving in wood screws, make pilot holes suitable for them in the wooden board. Apply the bit
to the screw head grooves and gently drive the screws into the holes.
{After rotating the rotary hammer at low speed for a while until the wood screw is partly driven into the
wood, squeeze the trigger more strongly to obtain the optimum driving force.
CAUTION:
Exercise care in preparing a pilot hole suitable for the wood screw taking the hardness of the wood
into consideration. Should the hole be excessively small or shallow, requiring much power to driver
the screw into it, the thread of the wood screw may sometimes be damaged.
6. Hammering only

LUBRICATION
Low viscosity grease is applied to this rotary hammer so that it can be used for a long period without
replacing the grease. Please contact the nearest service center for grease replacement when any grease is
leaking from loosened screw.
Further use of the rotary hammer with lock off grease will cause the machine to seize up reduce the
service life.
CAUTION:
A special grease is used with this machine, therefore, the normal performance of the machine may be
badly affected by use of other grease. Please be sure to let one of our service agents undertake
replacement of the grease.
MAINTENANCE AND INSPECTION
1. Inspecting the drill bits
Since use of a dull tool will cause motor malfunctioning and degraded efficiency, replace the drill bit
with new ones or resharpen them without delay when abrasion is noted.
2. Inspecting the mounting screws
Regularly inspect all mounting screws and ensure that they are properly tightened. Should any of the
screws be loose, retighten them immediately. Failure to do so could result in serious hazard.

3. 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.
4. Inspecting the carbon brushes (Fig.21)
The motor employs carbon brushes which are consumable parts. When they become worn to or near
“wear limit”, it could result in motor trouble. When an auto-stop carbon brush is equipped, the motor
will stop automatically.
At that time, replace both carbon brushes with new ones which have the same carbon brush numbers
shown in Fig.21
In addition, always keep carbon brushes clean and ensure that they slide freely within the brush holders.
5. Replacing a carbon brush (Fig.22)
{Disassembling
(1) Loosen the five screws on the main handle cover, and remove the main handle cove.
(2) Lift out the brush holder together with the carbon brush, while being very careful not to forcibly pull
the lead wires within the brush holder.
(3) Withdraw the insert piece, and remover the carbon brush from the brush holder.
{Reassembling
(1) Place a new carbon brush into the insert piece, and connect the brush terminal to the carbon brush.
(2) Return the brush holder and other parts to their original positions, as illustrated in Fig.22
(3) Place the lead wire in the specified position. Be very careful not to allow the lead wire to contact the
armature or rotating parts of the motor.
(4) Replace the main handle cover, while being careful to ensure it does not pinch the lead wire, and
secure it firmly with the five screws.
CAUTION:
Should the lead wire be pinched by the main handle cover or come in contact with the armature or
rotating parts of the motor, a serious danger of electric shock to the operator will be created. Exercise
extreme caution in disassembling and reassembling the motor, following the above procedures exactly.
Do not attempt to disassemble any parts other than those necessary to effect replacement of the carbon
brush.
