• 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. 24 & 25)
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. 26 & 27)
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.
Lubrication (Fig. 28)
Oil the chain (after removing the side cover R), the four
columns and the screws for elevating the main frame.
This periodic lubrication should be performed with
machine oil.
CAUTION:
• Oiling and all maintenance should be done with the tool
turned off and unplugged.

Always brush off dirt, chips and foreign matter adhering
to the roller surfaces, motor vents and drums.
