OPERATION

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 cut-
ting metal. Failure to do so will cause premature
blade wear.
• If the tool is operated continuously until the battery
cartridge has discharged, allow the tool to rest for
15 minutes before proceeding with a fresh battery.
Press the shoe firmly against the workpiece. Do not allow
the tool to bounce. Bring the blade into light contact with
the workpiece. Turn the tool on and wait until the blade
attains full speed. Then apply pressure to cut the work-
piece.
