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 refers 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. Protective 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.

6
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.

4. How to install tool
NOTE:
For tools such as a bull point and a cold chisel, use only XINPU genuine parts.
(1) To attach the tool (SDS max shank), insert it into the hole until it contacts the innermost end of the hole
as illustrated in Fig.1.
If you continue to turn the tool with slight pressure, you can feel a spot where there is a hitch. At that
spot, pull the grip to the direction of an arrow mark and insert the tool all the way until it hits the
innermost end.
Releasing the grip reverts the grip and secures the tool in place.
(2) Pull the tool to make sure it is locked completely.
(3) To remove the tool, fully pull the grip in the direction of the arrow and pull out the tool.
5. Regulating the number of rotations and hammering (Fig. 2)
This Rotary Hammer is equipped with a built-in electronic control circuit that can adjust and regulate the
number of rotations and times of hammering. This Rotary Hammer can be used by adjusting the dial,
depending upon the contents of operation, such as boring holes into fragile materials, chipping, centering,
etc.
The scale’1’ of the dial is designed for a minimum speed with the number of 250 rotations per minute
and 1400 times of blow per minute. The scale ‘6’ is designed for a maximum speed with the number of
500 rotations per minute and 2800 times of blow per minute.
CAUTION:
Do not adjust the dial during operation. Doing so can result in injury because the Rotary Hammer must
be held by only one hand, disabling the steady control of the Rotary Hammer.
HOW TO USE THE ROTARY HAMMER
1. How to drill holes (Fig. 3)
(1) Pull the switch trigger after applying the drill bit tip to the drilling position.
(2) It is unnecessary to forcibly press the rotary hammer main body. It is sufficient to slightly press the
rotary hammer to an extent that shavings are freely discharged.
CAUTION:
Although this machine is equipped with a safety clutch, if the drill bit becomes bound in concrete or
other material, the resultant stoppage of the drill bit could cause the machine body to turn in reaction.
Ensure that the main handle and side handle are gripped firmly during operation.
2. How to chisel or crush (Fig. 4)
By applying the drill bit tip to the chiseling or crushing position, operate the rotary hammer by utilizing
its empty weight.
Forcible pressing or thrusting is unnecessary.
3. When drilling at “rotation + hammering”:
If you switch the selector lever during motor rotation, the tool can start to rotate abruptly, resulting in
unexpected accidents. Be sure to switch the selector lever when the motor is at a complete stop.
(1) Switching to “rotation + hammering”
(a) Push the button, release lock and turn the selector lever clockwise.
(b) Align ▲of the selector lever and of the lever holder as illustrated in Fig.5.
(c) Release the button to lock the selector lever.
NOTE:
Turn the selector lever (do not push the button) to check if it is completely locked and make sure that it
does not turn.
4. When chipping and chiseling at “hammering”:
CAUTION:
○If the selector lever is switched during motor rotation, the tool can start to rotate abruptly, resulting in
unexpected accidents. Make sure to switch the selector lever when the motor is at a complete stop.
○If the bull point or cold chisel is used at the position of “rotation hammering”, the tool can start to rotate,
resulting in unexpected accidents. Make sure that they are used at the position of “hammering”.
(1) Switching to “hammering”
(a) Push the button, release lock and turn the selector lever counterclockwise.\
(b) Align ▲of the selector lever and of the lever holder as illustrated in Fig. 6.

12
(c) Release the button to lock the selector lever.
NOTE:
Turn the selector lever (do not push the button) to check if it is completely locked and make sure that it
does not turn.
(2)When fixing working positions of tools such as cold chisel, etc.,
(a) Push the button, release lock and turn the selector lever.
Align ▲of the selector lever and of the lever holder as illustrated in Fig. 7.
(b) Release the button to lock the selector lever.
(c) Turn the grip as illustrated in Fig. 8 and fix the tool to the desired working direction.
(d) Switch the selector lever to “hammering” according to the procedures mentioned in the above item (1)
and secure the position of the tool.
5. Install the stopper (Fig. 9)
(1) Loosen the side handle and insert the straight portion of the stopper into the handle bolt hole.
(2) Move the stopper to the specified position and rotate the grip of the side handle clockwise to fix the
stopper.
6. Warming up (Fig. 10)
The grease lubrication system in this unit may require warming up in cold regions.
Position the end of the bit so makes contact with the concrete, turn on the switch and perform the
warming up operation. Make sure that a hitting sound is produced and then use the unit.
CAUTION:
When the warming up operation is performed, hold the side handle and the main body
securely with both hands to maintain a secure grip and be careful not to twist your body by the jammed
drill bit.
USING DRILL CHUCK, CHUCK ADAPTER
Note that this machine can be used at “rotation only” if separately sold parts such as drill chuck and chuck
adapter are attached. Use it with the selector lever positioned at “rotation +hammering”.
CAUTION:
During operation, be sure to grip the handle and the side handle firmly to prevent your body from
swaying.
(1) Switching to “rotation +hammering”
For switching to “rotation + hammering”, follow the same procedures mentioned in [3. When drilling at
“rotation +hammering”].
(2) Drilling
(a) Even if you apply more-than-required pressure to the machine body, drilling can never be performed
as quickly as you expect. Applying more force or pressure to the machine body
than what is needed, on the contrary, damages the drill tip, resulting in the declined working
efficiency and shortened life of this machine.
(b) A drill can snap sometimes when drilling is almost finished. It is important to relax your thrusting
pressure when drilling is nearing the end.
HOW TO HANDLE A CORE BIT
When a core bit is used, large diameter 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 efficient 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. 11) Before that, feed oil the screw portion of core bit
shank for easy dismounting .
(2) Mount the core bit shank on the main body in the same manner as in mounting the drill bit and the bull
point. (Fig. 12)
(3) Insert the center pin into the guide plate until it reaches the extremity.

13
(4) Fit in the guide plate by aligning its concaved portion 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. 13)
2. Drilling holes
(1) Insert the plug into a receptacle.
(2) A spring is built in the center pin. By straightly and gently pressing it to the wall or floor surface, the
entire surface of the core bit tip attains contact to start the hole drilling job.
(Fig. 14)
(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 hole drilling job.
CAUTION:
When removing the center pin and guide plate, always disconnect the plug from the receptacle.
3. How to dismount the core bit
○By holding the rotary hammer (with the core bit inserted) in an upward position, drive the rotary hammer
to repeat impact operation two or three times, whereby the screw is loosened and the rotary hammer
becomes ready for disassembly.(Fig. 15)
○Remove the core bit shank from the rotary hammer, hold the core bit with one hand, and strongly strike
the head of the SDS max shank portion of the core bit shank with a manual hammer two or three times,
whereby the round head screw is loosened and the rotary hammer is ready for disassembly.(Fig. 16)
HOW TO REPLACE GREASE
This machine is of full air-tight construction to protect against dust and to prevent lubricant leakage.
Therefore, the machine can be used without lubrication for long periods. Replace the grease as described
below.
1. Grease replacement period
After purchase, replace grease after every 6 months of usage. Ask for grease replacement at the nearest
XINPU Authorized Service Center. Proceed for replacement of grease.
2. Grease replenishment
CAUTION:
Before replenishing the grease, turn the power off and pull out the power plug.
(1) Remove the crank cover and wipe off the grease inside. (Fig. 17)
(2) Supply 30g of XINPU Electric Hammer Grease A (Standard accessory, contained in tube) to the crank
case.
(3) After replenishing the grease, install the crank cover securely.
NOTE:
The XINPU Electric Hammer Grease A is of the low viscosity type. If necessary purchase from an
XINPU Authorized Service Center.
MAINTENANCE AND INSPECTION
1. Inspecting the tool
Since use of a dull tool will degrade efficiency and cause possible motor malfunction, sharpen or replace
the tool as soon as 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
The Motor employs carbon brushes which are consumable parts. When they become worn to or near the
“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 the figure. In addition, always keep carbon brushes clean and ensure
that they slide freely within the brush holders.

14
5. Replacing carbon brushes
Loosen the two set screws and remove the tail cover. Remove the brush caps and carbon brushes. After
replacing the carbon brushes, tighten the brush caps securely and install the tail cover with securely
tightening two set screws.
