RemedyUsed.
The thread may have alreadydeteriorated. The blade fixing screw
was a consumable. Replace it
periodically.

If the blade fixing screw was new, itmay have been tightened with aforce stronger than specified
because of adhesion of foreign
matter such as oil, or the thread on
the holder may have beendamaged.

If there is no improvement, ask us.

Not used.
The blade broke when 15 Is the blade new?
used.

It is recommended to tighten
screws with a torque screwdriver toensure accurate installation.

Not new

The blade broke possibly due toinstallation or deterioration (wear)of the blade.

Replace parts that need to be
replaced with reference to"Maintenance of the transducer" in"3. Periodic Maintenance" in"Chapter 5 Inspection andMaintenance".

New

Check whether the work piece isfixed properly.

Reconsider the teaching andcutting method.

If a new blade breaks, check thework piece material and thesituation of use, and then ask us.

A work piece isemitting smoke.

16After checking the situation of use, perform cutting suitable for the purpose withreference to "4. Cutting Test" in "Chapter 3 Installation and Preparation for Use".

Error cause

RemedyO/L

Large load isapplied to the blade.

Address the cause of overload with reference to "Major
Causes of Stopping Due to Overload and Action to Take" in"Chapter 6 When You Are in Trouble".

O/H OSC

Excessive heatingof the oscillator

1. Turn OFF the power.
2. Check if the surrounding space of the oscillator isobstructed and if the intake fan operates properly.
If heating subsides, resume operation.
In the case where operation with high load (load indicator
level 8 or more) continued and caused heating, lower thecutting speed or take other action so that the number oflights illuminated is less than 8.
If the cause of heating is unknown, ask us.

Error stop by an
external input

If the transducer was not connected, connect it and resume
operation after error recovery.
If the transducer generates excessive heat, follow thefollowing steps:
1. Turn OFF the power.
2. Check whether the cooling air for the transducer works
normally.
If heating subsides, resume operation.
If the cause of heating is unknown, ask us.
If an error is given even though there is no heating in thetransducer, disconnection is a possible cause. Replace thecable (sold separately).
An error stop occurred because of receiving an error signal
from an external device. Check the device connected to theexternal connection C receptacle.

Major causes of stopping due to overload and action to take (O/Lindicator lights up)
Examine the cause of overload following the table below.
If there is no relevant cause, or if the problem persists after you take remedial action, ask us.

When You Are in Trouble

Probable cause

RemedyHave you used a blade, tool, or parts thatare different in type from those included atthe time of purchase?

Installing a different type of product or a product offered by anoutside company results in failure of proper operation.
Use the same type of products as the accessories included at thetime of purchase.
We can produce custom-ordered parts and blades that are tailoredto specific needs. Ask us.

Have you used a transducer cable otherthan that included at the time of purchase?

Use of a cable whose length is different from that of the productincluded at the time of purchase may result in failure of proper
operation even if it is a genuine product.
If you want to change the cable length, ask us to readjust it.
If readjustment was previously made by us, the cable length given in
the specification pages of this manual may be different. Confirm itwith us.

Was oscillation turned ON with the blade
remaining in contact with or brought into
contact with a work piece?

A high load may be caused as a work piece moves together with theblade. Before use, turn ON oscillation with nothing in contact withthe tip parts (vibrating in the air).

Isn’t the blade in contact with an object
Use this device so that the blade does not come into contact with an(such as a jig and frame) other than the work object other than the work piece.
piece?
Isn’t the holder or the blade fixing screw incontact with the work piece?

Check to see if there is looseness or damage in the tip parts due torubbing with work pieces, and use this device so that an object otherthan the blade does not come into contact with the work piece.
If the tip parts are damaged, replace the parts.

Haven’t you tried to cut material (e.g., metaland glass) that is hard to cut even with anormal blade such as a cutter knife?

If it is difficult to perform work without causing an overload error,
adopt another cutting method.

Is it possible to cut a work piece without anoverload error being detected if you reduce
the feed speed?

If it is possible to cut a work piece without an overload error, thefeed speed and amplitude are considered to be optimum for thework piece and blade.

Does the blade edge orientation match thedirection of travel (feed direction)?

If the blade edge orientation does not match the direction of travel, it
may result in improper cutting or higher load.
Ensure that the orientation always matches the direction of travel.

Have you tested cutting by changing not
only the feed speed but also the amount ofamplitude?

If cutting has succeeded after change, the feed speed andamplitude are considered to be optimum for the work piece andblade.
