1. General Power Tool Safety Warnings
WARNING Read all safety warnings and all instructions. Failure to
follow the 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 safety
a) Keep work area clean and well lit.Cluttered or dark areas invite accidents.

4
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. Using a cord suitable for outdoor use reduces the risk of electric
shock.
f) If operating a power tool in a damp location is unavoidable, use a residual
current device (RCD) protected supply. The 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 personal protective equipment. Always wear eye protection. Protective
equipment such as dust masks, non-skid safety shoes, hard hats, or hearing
protection used for appropriate conditions will reduce personal injuries.
c) Prevent unintentional starting. Ensure the switch is in the off-position before
connecting to the power source and/or battery pack, picking up, or carrying the

5
tool.
Carrying power tools with your finger on the switch or energizing power tools with
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 jewelry. Keep your hair, clothing,
and gloves away from moving parts. Loose clothes, jewelry or long hair can be
caught in moving parts.
g) If devices are provided for connecting dust extraction and collection facilities,
ensure these are connected and properly used. The use of dust collection can
reduce dust-related hazards.
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 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 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.
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 tool’s
operation. If damaged, have the power tool repaired before use. Poorly maintained
power tools cause many accidents.
f) Keep cutting tools sharp and clean. Properly maintained cutting tools with sharp
edges are less likely to bind and are easier to control.
g) Use the power tool, accessories and tool bits, etc., following these instructions,

6
considering the working conditions and the work to be performed. Using the power
tool for operations different from those 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.
2. Diamond Core Drill Safety Warnings
1. Use auxiliary handles supplied with the tool. Loss of control can cause
personal injury.
2. Consider work area environment: Don’t use diamond core drill in damp or wet
locations. Don’t expose the diamond core drill to rain. Keep the work area well-lit.
In particular, no flammable liquids or gases must be present. The series motor
produces sparks during regular rotation. The sparks may cause the risk of fire.
3. Grounding of class I tools is necessary while in use to protect you from electric
shock. Class I tools are equipped with an approved three-conductor cord and
three-prong grounding-type plug. The green/yellow conductor in the cord is the
grounding wire, one end of wire is in the grounding sign of outer tool shell, the
other end of wire is connected with the ground wire of plug. Never connect the
green/yellow wire to a live terminal.
4. Warning ！The socket must be fitted with grounding, don’t insert
class I tools into the socket without grounding.
5. Use extension cords when tool is used outdoors or indoors, use special
extension wire board. Use only three-conductor cord and with reliable grounding.
6. Take care of the downward direction in the high position, safety belt and safety
cap, etc., are recommended.
7. In order to avoid unintentional electric shock, please check the grounding
condition of electrified body in working area before operating, it is not allowed to
operate the tool under the uncertain condition, once the drill bit touched the
electrified body in the wall, floorboard or baseboard, the electrified outer shell of
drill may cause personal injuries.
8. The safety equipment is recommended when drilling on high the ceiling to

7
avoid the drill core injuring the persons downstairs or damaging the property
downstairs.
9. Connecting the soft pipe with the inner diameterΦ16mm to the adaptor of the
valve.
10. Please ensure that there is no water leak so that it will not dampen the motor
when you use the liquid and the attachments.
11. Usually inspect the hoses and other critical parts of the tool which could
deteriorate. When a water leak appears from the testing hole of the gearbox, you
must turn off the tool immediately and then replace the rubber seal.
12. Replacement of the plug or the supply cord shall always be carried out by the
manufacturer of the tool or his service organization;
13. Keep liquid clear off the parts of the tool and away from persons in the
working area in order that the water can not enter into the electronic equipment of
the tool and keep your safety. It must be use catchment set when the machine
working with elevation.
3. HANDLING INSTRUCTIONS
1. Check the voltage:
Make sure the voltage is the same as that indicated on the board of the tools, the
voltage in the circuits should be kept at +/-5%.
2. How to install bit:
Installing the diamond-thin bit carefully, the end thread shall match with the end
output shaft. The end thread should be smeared with grease firstly, after tightening
the drill bit, let it idly run, do make sure that its radial motion corresponds with the
general requirement, then you can operate the drill.
3. Leave some water in the water switch of drill.
4. Material:
When drilling on the reinforced concrete, if the drill bit touches the steel bar, the
current will suddenly increase, the motor will vibrate, and the bit will be overloaded.
At this time, the drill thrust should be reduced properly. The low current will have
an adverse effect on the bit speed and the bit. If the gravel falls into the drill or the
drill touches the steel bar, the drill can get stuck, causing high current and clutch
slip. At this point, close the tool, remove the bit, and clean the clip notch. Wait 3

8
minutes for the bit to cool and then restart the switch to continue drilling. If the
clutch continues to slip, please stop drilling and re-tighten the clutch.
5. Remove drill core:
When the drill bit almost drills through the floorboard or wall etc materials, be
careful in reducing its drill speed to avoid drilling forcibly. When drilling again,
please shut off the tool, remove the drill bit and clean its wall with water, after
cleaning the chip, beat the drill slightly with the wood stick, be careful in removing
the drill core and damaging the drill bit, then installing the drilling to continue
operating.
6. Keep the motor ventilated and cool down:
During operating, the ventilated notch of the motor should not be clogged with dirt
to avoid the higher temperature affecting the motor's life or burning down the
winding.
7. Waterless operation is forbidden:
When operation, there should be plenty of water flow onto the surface of the drill
bit to cool down, and the mud can be washed out to avoid damaging the drill bit
and sealing washer.
8. Avoid dampening the motor:
Do keep the enclosure of the motor away from the water to avoid reducing its
insulating performance or leaking electricity. Only use the machine with the
direction of vertical downward!
9. Drill vibrated
The gap between the elevating body and square pipe and rack increased may
cause the drill vibration. At this time, please shut off the tool, adjust the track lining
or idle wheel on elevating body, and tighten some relative bolts to adjust it to
proper gap.
10. When adjusting the speed, you must stop the machine before turning the knob.
It is not allowed to turn the knob when the machine is working, otherwise the gear
may be damaged.
