1. Brush holder cap
2. Screwdriver
• 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
002518
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.
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.

Use a screwdriver to remove the brush holder caps. Take out

the brush holder caps.
