Always turn off the switch and unplug from the power
outlet before starting check or maintenance work.
Regularly check the bolts used to fix parts to see if there is any looseness. If
looseness is found, tighten again securely.
If the machine is used with loosened bolts, an accident leading to injury might occur.
If the air vent is clogged, overheating occurs, which might result in burnout. (Refer to Figure 1)
After each operation of about 200 hours, cleanly wipe off the grease on the flexible
shaft and bearing, then apply new grease evenly on the entire surface of the shaft. Pull
out the rotor from the vibrating case, then wash well the inside of the case and the
bearing of the rotor. When a new bearing is used, fill it sufficiently with grease. Do not
put grease inside the case.
Use heat resistant grease that will not be deteriorated by change in temperature. Use
[for example, Pyronoc No.2 of Nippon Oil Corporation (previously Nisseki Mitsubishi)].
For vibrator repair, please contact your distributor.
This product complies with the applicable safety requirements. Please do
not try to make alterations.
For repair, please contact your distributor.
If repair is done by someone without proper knowledge and skill, it might
result in the performance of the machine being compromised, and even
there might arise a risk of accident or injury.
Check of carbon brush
If you notice a drop in motor revolution or lowering of the force, remove
the back cover of the motor to check the wear of carbon brush.
For MGX model, the carbon brush should be replaced with a new one
when its remaining length is less than 5mm (length of new brush is
12mm).
Contact your distributor if you need to replace a carbon brush.
Make sure to use a MIKASA genuine carbon brush when replacing
the carbon brush with a new one.
