General Power Tool Safety Warnings
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.

6
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.

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 flex sheath to the direction of an arrow mark and insert the tool all the way until it
hits the innermost end.
Releasing the flex sheath reverts the flex sheath 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 flex sheath 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
speed adjuster knob, depending upon the contents of operation, such as boring holes into fragile
materials, chipping, centering, etc.
The scale’1’ of the speed adjuster knob 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 speed adjuster knob 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.

securely with both hands to maintain a secure grip and be careful not to twist your body by the
jammed drill bit.
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 dill bit 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) Fit in the dill bit by aligning its screw portion with the core bit tip. When the position of the
concave is shifted by turning the turn dill bit clockwise, the dill bit 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) By straightly and gently pressing dill bit 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 dill bit from the core bit and continue the hole drilling job.
CAUTION:
When removing the dill bit, 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

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 of specification with standard. In addition, always keep carbon brushes clean
and ensure that they slide freely within the brush holders.
