instructions listed below may result in electric shock, fire and/or serious
injury.
Save all warnings and instructions for future reference.
General Power Tool Safety Warnings – Work area safety
a) Keep work area clean and well lit. Cluttered or 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.
d) Before work to tie the cuffs, women need to wear a good woman hat, long
hair hidden in the hat, is strictly prohibited to wear gloves.When the
construction is completed, the switch must be turned off before leaving.
General Power Tool Safety Warnings – 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 tool in a damp location is unavoidable, use a ground
fault circuit interrupter (GFCI) protected supply. Use of an GFCI reduces the
risk of electric shock.
General Power Tool Safety Warnings – 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 a dust mask, non-skid safety shoes, hard hat 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 power source and/or battery pack, picking up or carrying
the tool.
Carrying power tools with your finger on the switch or energising 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 and
clothing 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
dust collection can reduce dust-related hazards.
h) Do not let familiarity gained from frequent use of tools allow you to
become complacent and ignore tool safety principles. A careless action can
cause severe injury within a fraction of a second.
I) This product is not a toy. Keep it out of reach of children.
J) Only use safety equipment that has been approved by an appropriate
standards agency. Unapproved safety equipment may not provide adequate
protection. Eye protection must be ANSI-approved and breathing protection must
be NIOSH-approved for the specific hazards in the work area.
K) Do not lay the tool down until it has come to a complete stop. Moving parts
can grab the surface and pull the tool out of your control.
L) When using a handheld power tool, maintain a firm grip on the tool with
both hands to resist starting torque.
M) Do not leave the tool unattended when the Battery Pack is connected. Turn
off the tool, and remove the Battery Pack before leaving.
N) People with pacemakers should consult their physician(s) before use.
Electromagnetic fields in close proximity to heart pacemaker could cause
pacemaker interference or pacemaker failure.
O) The warnings, precautions, and instructions discussed in this instruction
manual cannot cover all possible conditions and situations that may occur. It
must be understood by the operator that common sense and caution are factors
which cannot be built into this product, but must be supplied by the operator
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 and/or remove the battery pack,

is not more than ±5%. If it is more than that, it will cause motor burning and
leakage accidents.
j) During construction, please pay attention to avoid water entering the motor
or blocking the ventilation hole, so as not to reduce the heat dissipation
performance of the motor and cause the motor to burn down.
k) In the steel plate construction, please pay attention to the safety of the
lower layer of personnel and goods, iron beam and column drilling, pay
attention to the safety of the structure of the building.
L) In suspension operation, the safety belt must be tightly tied and the
magnetic drill fixed to prevent sudden power failure or power failure caused
by accidents.
M) Do not cut the power cord or change the plug yourself. This will cause the
machine to burn out.
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.
b) In any case, it should be started in no-load state. It is forbidden to
start with load, so as to avoid damage to the machine. Please pay attention to
the stability of the magnetic drill when working at high altitude, so as to
prevent the machine from falling down.
c) Ensure that the ground cable is grounded reliably.

OPERATION AND USE
-
The drill bit must be sharp. When installing the hollow drill, insert the central needle into the hollow drill, install the hollow drill on the output shaft, and finally, tighten the fixing screw to secure the hollow drill.
-
Place the magnetic drill near the required drilling position, plug in the power plug, align the drill bit with the machining position, and then turn on the switch of the electromagnet so that the electromagnet can be absorbed on the surface of the magnetic materials such as steel. (plate thickness more than 15mm) (Pay attention to selecting appropriate adsorption materials and ensure that there is no debris on the adsorption surface, check whether the magnetic force is normal).
-
The machine should be fastened with a safety belt when working on the side or top.
-
Thread one end of the safety belt into the handle hole of the frame, tie the other end to the strong frame, and then buckle into the fasteners
(Try to pull with your hand, it should not be loose and displacement). -
Turn on the power switch to check whether the drill bit is beating and the sound is stable. If everything is normal, open the water valve first so that the cutting fluid in the oil can flow out, and then turn the handle to feed ( Note: Do not open the water valve when working on the side and top position)
-
Feed should be slow at first. Do not exert too much in case of overload.
-
If the motor suddenly stops or gets stuck due to a fault, the drill control switch 9 must be turned off immediately ( Note: do not turn off the electromagnet switch 5).
After continuous use for 2-3 hours, you need to rest to prevent the electromagnetic seat from burning out due to overheating. -
When the carbon brush is worn out, please replace it in time (both of them should be replaced at the same time).
COOLING DOWN AND ADJUSTMENT OF THE TRACK
- Fix B1 at B, then connect B2 to B1 and C.
- Turn the joystick to determine whether the tightness of the track meets the drilling requirements. If the tightness is not ideal, you can adjust it with the open wrench and the hex wrench in the attachment.
a) Loosen the hex nut at place A with an open wrench.
b) Use the hex wrench to adjust the set screw at A and turn the joystick 7 simultaneously to feel whether the tightness of the track reaches the ideal state of drilling.
c) After adjustment, tighten the hex nut at A with the open-end wrench.
Note: The tightness of the track has been adjusted before leaving the factory. If there has been no strong vibration, fall, and other conditions, please do not adjust.
