Replacing Carbon Brushes; Maintenance - Makita 2012NB Instruction Manual

Switch on the tool and wait until the blades attain full
speed. The workpiece should not be in contact with the
feed roller when you turn the tool on.
Then insert the workpiece flush with the table top.
When cutting a long or heavy workpiece, lift up its end
slightly at the start and the end of the cut to avoid
gouging or snipping at the extreme ends of the
workpiece.
The use of the tool top enables quick, effortless return of
the workpiece to the infeed table side. This is especially
convenient with two operators.

The workpiece with the following dimensions

between two feed rollers is 129 mm. Do not try to
cut them.

CAUTION:
Stop the tool when the workpiece has stalled.
•
Allowing the tool to run with a stalled workpiece
causes rapid wearing of the feed rollers.

MAINTENANCE

CAUTION:
Always be sure that the tool is switched off and
•
unplugged before attempting to perform inspection
or maintenance.
Never use gasoline, benzine, thinner, alcohol or the
•
like. Discoloration, deformation or cracks may

The height of sub-table is factory-adjusted. If further
adjustment is necessary, proceed as follows.
Place a postcard on the table and also place a ruler on
the postcard. Turn the adjusting screw with the hex
wrench until the end of the sub-table contacts the ruler.
Now the end of the sub-table is from 0.1 mm to 0.3 mm
above the table surface.

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.
