Maintenance - Makita 2012NB Instruction Manual

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 con-
venient with two operators. (Fig. 19)
CAUTION:
• The workpiece with the following dimensions cannot be fed into the tool because the interval between two feed roll-
ers is 129 mm. Do not try to cut them. (Fig. 20)

• 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.
Adjusting height of sub-table (Fig. 21 & 22)
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 (Fig. 23 & 24)
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 blades sharp
Dull blades can cause rough finish, an overload of the
motor and dangerous kickback of the workpiece.
Replace dull blades immediately.
