OPERATION

005790
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 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.

MAINTENANCE

CAUTION:
Always be sure that the tool is switched off and
•
unplugged before attempting to perform inspection
or maintenance.
