GENERAL SAFETY RULES
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
WORK AREA
Keep work area clean and well lit. Cluttered
and 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.
ELECTRICAL SAFETY
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
conditions. Water entering the 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
PERSONAL SAFETY
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.
Use safety equipment. Always wear eye
protection. Safety equipment such as dust
mask, non-skid safety shoes, hardhat, or
hearing protection used for appropriate
conditions will reduce personal injury.
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.
Remove any adjusting key or wrench before
turning the power tool on. A wrench or key
left attached to a rotating part of the power tool
may result in personal injury.
Do not overreach. Keep proper footing and
balance at all times. This enables better
control of the power tool in unexpected
situations.
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.
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.

POWER TOOL USE AND CARE
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.
Do not use the tool if the switch does not
turn it ON or OFF. Any power tool that cannot
be controlled with the switch is dangerous and
must be repaired.
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.
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.
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.
Keep cutting tools sharp and clean. Properly
maintained cutting tools with sharp cutting
edges are less likely to bind and are easier to
control.
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

When self-drilling anchors (Fig 4) are used,
the anchors can be driven in. In this case,
use the optional accessories for self-drilling
anchors such as the anchor adaptor.
1/ When an impact anchor adaptor is
used,(1) attach the turning handle to the
anchor adaptor and create a base hole by
applying drill impact to the hole position while
manually turning the handle. (Fig 5). In this
case the plug is not attached to the anchor.
(2) When a predetermined depth has been
attained, pull out the anchor tentatively. (Fig
6). (3) By employing a syringe, blow out the
chips and dust.
(4) Attach the plug to the anchor tip and drive
in the anchor again with the electric hammer
drill.
(5)After driving in the anchor, use the drift
key to separate the anchor. (see Fig 7)
(6)By employing a manual hammer or pliers,
snap off the tapered portion of the anchor.
(see Fig 8)
Caution.
Since the snapped off tapered portion will fly
about, pay attention to the snapping direction
As this may cause injury.
2/ When a rotation and impact anchor
adapter is used,
(1) attach a self-drilling anchor to the anchor
adaptor.
(2) Turn on the switch and drill a base hole
with the self-drilling anchor.
At the start of the hole-drilling slightly tilt the
drill to determine the hole position.
(3) After drilling clear out dust from the hole
with the syringe, attach the plug to the
anchor tip and drive in the anchor with a
hand hammer.
(4) For further operations, follow procedures
(5) and (6) described above. When an impact
anchor adaptor is used.
When a taper shank adaptor is used
(1)Attach a drill bit with tapered shank to the
taper shank adaptor.
(2) Turn on the switch, and drill a hole until it
reaches the hole depth indicating groove.
(see Fig 9)
(3) After clearing out the dust and particles
with the syringe, attach a plug to the anchor
tip and drive in the anchor with a manual
hammer or pliers.
How to handle a core bit
When a core bit is used, large caliber holes
and blind holes can be drilled. In this case,
use optional accessories for core bits (such
as a center pin and core bit shank) for more
rational operation.
1. Mounting.
Caution
Prior to mounting a core bit, always
disconnect the plug from the power supply
receptacle.
(1) Mount the core bit on the core bit shank
(Fig 10) make sure you oil the screw portion
of the core bit shank for easy dismount.
(2) Mount the core bit shank on the drill main
body in the same manner as in mounting the
drill bit and the bull point. (Fig 11)
(3) Insert the center pin into the guide plate
until it reaches the extremity.
(4) Fit in the guide plate by aligning its
concaved position with the core bit tip when
the position of the concave is shifted by
turning the guide plate right or left, the guide
plate never slips off even when the drill is
used in a downward direction. (Fig 12)
2. Drilling holes.
(1) Insert the plug into a power supply
receptacle.
(2) A spring is built in the center pin. By
straight and gentle pressing to the wall or
floor surface, the entire surface of the core bit
tip attains contact to start the hole drilling job.
(3) When the hole depth reaches
approximately 5mm, the hole position can be
determined. Then remove the center pin and
guide plate from the core bit and continue the
drilling job.
Caution
When removing the center pin and guide
plate, always disconnect the plug from the
power supply receptacle.
15
ASSEMBLY & OPERATION

How to dismount the core bit
(1) By holding the drill (with the core bit
inserted) in an upward position, drive the drill
to repeat impact operation two or three times,
whereby the screw is loosened and the drill
becomes ready for disassembly. (2)
Remove the core bit shank from the drill, hold
the core bit with one hand and strongly strike
the head of the hexagonal portion of the core
bit shank with a hand hammer two or three
times, whereby the round head screw is
loosened and the drill is ready for
disassembly.
Oil feeding
Caution.
Prior to oil feeding, always disconnect the
plug from the power supply receptacle.
Since an oil chamber is built in this electric
hammer drill, it can be used for
approximately 20 days without supplying
lubrication oil, assuming that the drill is used
continuously 3 –4 hours daily.
Feed oil into the oil tank as described below
before using the hammer drill. (see Fig 15
and 16)
(1) When the drill is held upright look through
the oil gauge window to see if oil is visible, if
no oil shows oil must be installed before
operating. If drill is used without oil this could
seriously damaged the drill and forfeit any
warranty given
(2) Before feeding oil, use the provided
wrench to remove the oil gauge. Be careful
not to lose the rubber packing attached below
the oil gauge.
(3) Check the oil level once daily, confirming
that oil is filled.
(4) After feeding oil, securely clamp the oil
gauge.
Note: Oil for the electric hammer drill is sold
separately, use Shell oil (ROTELLA 40)
engine oil or equivalent, this is sold at most
shop or filling stations anywhere.
Maintenance and inspection
1. Inspecting the tool
When using dull tool bits this can cause
motor malfunction and degraded efficiency.
Always replace dull bits with new ones
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 injury.
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 17)
The motor employs carbon brushes which
are consumable parts. Since an excessively
worn carbon brush could result in motor
trouble, replace the carbon brush with a new
one which has the same carbon brush no.
shown in the figure when it becomes worn to
or near the “wear limit” in addition always
keep carbon brushes clean and ensure that
they slide freely within the brush holders.
Replacement steps.
The carbon brush can be removed by
removing the tail cover and brush cap in that
order at the interior.
5. Inspection of the dust cover.
The function of the dust cover is to protect
the inside mechanism.
When the interior of the dust cover is worn,
replace with new dust cover. To remove the
dust cover pull it out.
INSTALLING BITS
Never hold the chuck body with one hand
and use the drill power to rotate the drill
body to loosen or tighten bits. You may
severely injure your hand.
ASSEMBLY & OPERATION
MAINTENANCE
16

Be prepared for binding and bit
breakthrough. When these situations occur,
the drill bit has the tendency to grab the
workpiece. This action will kick the drill
opposite to the direction of drill bit rotation
and could cause loss of control when
breaking through material as you complete
drilling the hole. If you are not prepared, this
loss of control can result in possible serious
injury.
GENERAL
When servicing, use only identical
replacement parts. Use of any other part
may create a hazard or cause product
damage.
DO NOT use solvents when cleaning plastic
parts. Most plastics are susceptible to damage
from various types of commercial solvents and
may be damaged by their use. Use clean cloth
to remove dirt, dust, oil, grease etc.
Do not at any time allow brake fluids,
gasoline, petroleum-based products,
penetrating oils, etc. to come in contact with
plastic parts. They contain chemicals that
can damage, weaken or destroy plastic.
DO NOT abuse power tools. Abusive practices
can damage the tool as well as the workpiece.
DO NOT attempt to modify tools or create
accessories not recommended. Any such
alteration or modification is misuse and
could result in a hazardous condition
leading to possible serious injury. It will also
void the warranty.
