OPERATION

MAINTENANCE

1. Limit mark

CAUTION:
• Always press the shoe firmly against the workpiece
during operation. If the shoe is held away from the
workpiece during operation, strong vibration and/or
twisting will be produced, causing the blade to snap
dangerously.
• Always wear gloves to protect your hands from hot flying
chips when cutting metal.
• Be sure to always wear suitable eye protection which
conforms with current national standards.
• Always use a suitable coolant (cutting oil) when cutting
metal. Failure to do so will cause premature blade wear.
Press the shoe firmly against the workpiece. Do not allow the
005790
tool to bounce. Bring the blade into light contact with the
workpiece. First, make a pilot groove using a slower speed.
Then use a faster speed to continue cutting.
CAUTION:
• Always be sure that the tool is switched off and
unplugged before attempting to perform inspection or
maintenance.

when they wear down to the limit mark. Keep the carbon

tical carbon brushes.
