pipe. This will result in an explosion and severe 

injuries or death.

 Always check the grounding conductor. If you have 

any doubts about the grounding conductor contact a 

licensed electrician.

 Wiring connections to a grounding rod require the 

expertise of a licensed electrician. Do not attempt 

the wire connections yourself. Always contact a 

licensed electrician.

 Do not abuse the power cord. A damaged power 

cord can cause an electrocution. A damaged power 

cord can cause 

fires.

 Always inspect the cord. If the 

cord is damaged, do not use the magnetic drilling 

machine.

 Do not carry the machine by the cord. Do not pull 

the cord to disconnect it from a socket.

 The cord can become damaged from heat, contact 

with sharp objects or from being twisted. Always 

inspect the cord. Do not use the machine if the cord 

is damaged.

 Always use a ground fault circuit interrupter. The use 

of a ground fault circuit interrupter may be required 

by government regulations. The failure to use a 

ground fault circuit interrupter may result in electric 

shock.

 Avoid starting the magnetic drilling machine abruptly 

or unintentionally.

 Always make sure that the switch is turned off before 

connecting the power source.

 Always disconnect the power source and turn off 

the switch before setting up for work operations. 

Always  disconnect  the  power  and  turn  off  the 

switch when inspecting work. Always disconnect 

the power and turn off the switch before attempting 

any maintenance. Failure to disconnect the power 

and turn off the switch during set up, inspection 

or maintenance can cause accidents and severe 

injuries.

ABOUT YOUR NITTO PORTABLE MAGNETIC 

DRILLING MACHINE

DANGER

Do not use your portable drilling machine on the 

ceiling.

 Use of the portable drilling machine on the ceiling 

is dangerous. The machine could fall. The falling 

machine could cause severe injuries or death. (Fig.1)

Fig. 1

WARNING

Do not use the Magnet for more than five hours.

 More than 

five

 hours of uninterrupted operation may 

cause a fire. Five hours of uninterrupted operation 

generates extreme heat in the Magnet. This heat 

can cause a fire. Do not touch the Magnet. When 

the Magnet is hot, touching it will cause a severe 

burn injury. Never use the Magnet for more than 

fiv

e continuous hours. When you are not using the 

Magnet, turn the switch to the "OFF” position and 

pull the plug out of the power source.

Do not use the Drill Motor for over 30 minutes.

 Uninterrupted operation of the Drill Motor for over 30 

minutes generates heat. This heat can cause a 

fire.

 

Never use the Drill Motor for over 30 minutes. When 

you are not using the Drill Motor, turn the switch to 

the "OFF' position and pull the plug from the power 

source.

Use only on magnetic materials.

 Your  portable  drilling  machine  cannot  be  used 

on non-magnetic materials, such as aluminum, 

stainless steel, copper or alloys. The Magnet will not 

work on non-magnetic materials. Attempting to use 

the Magnet on non-magnetic materials could cause 

an accident.

Use caution during wall operation.

 When using your portable magnetic drilling machine 

on a magnetic wall, always use caution. 

 Never stand under the machine.

  * Never allow anyone to stand under the machine.

  *  Never  put  any  part  of  your  body  under  the 

machine.

  * If the machine falls, it could result in severe injury 

or death.

 Always remove cutting oil from the tank before using 

the machine on a wall. You must manually apply 

cutting oil to the cutting tool.
