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.
Always use a suitable coolant (cutting oil) when cutting
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. 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 the
battery cartridge is removed before attempting to
perform inspection or maintenance.
Replacing carbon brushes
Remove and check the carbon brushes regularly. Replace
when they wear down to the limit mark. Keep the carbon
brushes clean and free to slip in the holders. Both carbon
brushes should be replaced at the same time. Use only iden-
tical carbon brushes.
