CAUTION:
• Be very careful that the blade has been properly
mounted on the tool spindle between the inner
flange and the lock nut. Be sure to securely tighten
the lock nut.
Set the depth of cut to "MAX". Rest the base on the floor
(when trimming the wall panels) or the wall (when trim-
ming the ceiling panels). Using the floor or wall as a
guide, trim wall or ceiling panels. Feed in the direction of
the arrow.

CAUTION:
• Before trimming the panels, check the wall or ceil-
ing carefully to avoid cutting the electrical wires,
nails or other foreign materials.
• Always reinstall the rubber facing after trimming the
panels. If cutting slots for biscuits without the rubber
facing installed properly on the tool, the tool might
slip unexpectedly on the workpiece, causing dan-
gerous loss of control of the tool. When installing
the rubber facing, always hook it onto the inside of
the front opening.

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 identical carbon brushes.
Use a screwdriver to remove the brush holder caps. Take
out the worn carbon brushes, insert the new ones and
secure the brush holder caps.
