This instruction manual describes the correct operation method of MGX portable vibrator and its easy
inspection and maintenance. To enhance your work efficiency and to make your work more effective,
please read this manual before using the vibrator.
After you finish reading, please keep this manual at hand so that you can refer to it whenever necessary.
For repair parts, parts lists, service manuals and repair requests, please contact your distributor, our sales
office or Mikasa Parts Service Center.

Portable vibrator is for concrete compaction.
During concrete casting, insert the vibrating end of this machine into the concrete. Gap will be eliminated
from the concrete filled in the form, and the air bubbles contained in the concrete will be removed, which
results in nice-looking well compacted concrete finish of high strength.
Concrete casting in an area deep down the ground or anywhere far from the power source can be done
easily by extending the cord. Because this vibrator is small and light, long work and machine handling can
be done easily and safely.
Do not use this vibrator for purposes other than concrete compaction. Also, do not remove the shaft to alter
the motor and shaft to use them for other applications.
To prevent the risk of electrification, make sure to use a breaker at the power source.
Do not hold the vibrating head and the vibrating area near the vibrating head while you work. There is a
risk of vibration induced disease.
The portable vibrator consists of commutator motor part, vibration generating end part and flexible
hose/flexible shaft part that connects the commutator motor to the vibration generating end. The
combination of flexible hose/shaft part and motor part can be changed to meet the needs of each specific
application.
The electricity from the power source runs the commutator motor. Via the flexible shaft, the motor running
at high speed rotates the eccentric rotor, which makes the vibrating head to vibrate for concrete
compaction.
A switch is used to turn on and off the commutator motor.
This vibrator is marked with a “ ” symbol because two insulators are used as double insulation between
the electricity conducting part and the outside frame that comes into contact with people.
Double insulation tools are highly safe against electrification.
If the existing part is replaced with a different part, or when the parts are assembled incorrectly, double
insulation structure will be lost, and the vibrator might become unsafe to operate.
For disassembly/assembly of electric system and parts change or repair, please contact your distributor.
