3.0 Safety Guidelines
3.1 Warning Sign
!This sign points to special safety features on the machine.
The MEGA-M250 abrasive cutter has been designed for cutting metallographic specimens.
DO NOT CUT oversize samples. Always follow proper operational guidelines and avoid
contact with moving parts, lubricants and abrasives. Seek appropriate medical care for
cutting injuries.
3.3 Emergency Statement
!
Before operating, cutting chamber hood must be closed. After cutting, the safety latch
will not open for approximately 5 seconds after pressing the stop (red) button.
!
Use only certified cut-off wheels from a professional supplier. Improper blades selection
voids warranty. (For appropriate blade selection, refer to the Abrasive Blade Selection
Guidelines Chart in Section 4.3)
!Disconnect power before opening the main unit.
!Replacement parts should be installed only by qualified personnel.
!Securely clamp the part / sample to the working table. During cutting, consider that the
part may pinch and cause jamming of the cut-off wheel. Use the appropriate clamping
devices to avoid this occurrence.
!Never start a cut under load.
!Make sure that the cut-off blade is rotating down and into the sample.
3.2 Safety Precautions
7
Careful attention to this instruction manual and the recommended safety guidelines is
essential for the safe operation of the MEGA-M250.
Proper operator training is required for the safe operation of the MEGA-M250. Any
unauthorized mechanical and electrical change, as well as improper operation, voids all
warranty claims. All service issues need to be reported to the manufacturer / supplier.

Please read this instruction manual carefully and follow all installation, operating and safety guidelines.
For proper clamping, use the appropriate clamping vises to securely hold the sample in
place. It is recommended that both sides of the part be clamped to avoid pinching of the
blade (possibly breaking the blade) and to minimize burning of the workpiece during
cutting.
For proper fixturing, take into account the initial stress on the samples.

5.0 Maintenance
5.1 Introduction
5.2 Cleaning outside cabinet
The cabinet and front shield should be cleaned occasionally with a moistened cloth. Do not
use any chemicals or cleaning abrasives. We recommend an anti-condensation gel be used
on the front panel.
The recommended maintenance for the MEGA-M250 includes the following:
1. Use an anti-corrosion cutting fluid such as the MAXCUT 2 or an oil-emulsion cutting fluid
such as the MAXCUT OL-1000. It is recommended that the cutting fluid be changed every
50 cuts or weekly for maximum effectiveness.
2. Rinse and dry the table and vises after use.
3. When the cutter is not in use, OPEN the HOOD to prevent humidity and corrosion build-up
inside the cutting chamber.
4. If cutter will not be used for an extended period of time, coat the table and vises with a
water displacement oil such as WD-40.
5. Use only recommended abrasive blades to minimize overheating the bearings and motor.
Do not exceed the recommend amp rating of the motor.
6. Grease the appropriate fittings periodically (minimally after every 200 cuts or every other
month, whichever occurs first).
7. Immediately replace any broken or damaged parts.
Note: corrosion is considered a maintenance issue and not a warranty issue
