Makita DDF486 Instruction Manual page 129

Do not start the cutting operation in the workpiece.
•
Let the wheel reach full speed and carefully enter
into the cut moving the tool forward over the
workpiece surface. The wheel may bind, walk up
or kickback if the power tool is started in the
workpiece.
During cutting operations, never change the angle
•
of the wheel. Placing side pressure on the cut-off
wheel (as in grinding) will cause the wheel to crack
and break, causing serious personal injury.
A diamond wheel shall be operated perpendicular
•
to the material being cut.
Operation with wire cup brush
(optional accessory)
CAUTION:
Check operation of brush by running tool with no
•
load, insuring that no one is in front of or in line
with brush.
Do not use brush that is damaged, or which is out
•
of balance. Use of damaged brush could increase
potential for injury from contact with broken brush
wires.

Remove the battery cartridge from the tool and place it
upside down allowing easy access to spindle. Remove
any accessories on spindle. Thread wire cup brush onto
spindle and tighten with supplied wrench. When using
brush, avoid applying too much pressure which causes
over bending of wires, leading to premature breakage.
Operation with wire wheel brush
(optional accessory)
CAUTION:
Check operation of wire wheel brush by running

tool with no load, insuring that no one is in front of
or in line with the wire wheel brush.
Do not use wire wheel brush that is damaged, or

wheel brush could increase potential for injury
from contact with broken wires.
ALWAYS use guard with wire wheel brushes,
