Replacing Carbon Brushes; Maintenance - Makita 2012NB Instruction Manual

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.

CAUTION:
The workpiece with the following dimensions
•
cannot be fed into the tool because the interval
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 result.

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

001145
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.

Keeping planer blades sharp
Dull blades can cause rough finish, an overload of the
motor and dangerous kickback of the workpiece.
Replace dull blades immediately.
