Makita 2012NB Instruction Manual page 6

Clean out all chips, dust, pitch or foreign matter
•
adhering to the drum or blades before installing the
blades.
Use blades of the same dimensions and weight , or
•
drum oscillation/vibration will result, causing poor
cutting action and eventually, tool breakdown.
Replace both blades at the same time.
•
The disposable-type blade has a cutting edge on
•
both sides. When one cutting edge becomes dull,
you can use the other cutting edge. Always remove
resin and dirt sticking to the reverse side of the
blade before using the other cutting edge. This
blade must not be re-sharpened. When both cutting
edges become dull, the blade should be carefully
thrown away.
1. Removing blades
Loosen the thumb screw which secures the chip cover
and remove the chip cover. Remove the screws which
secure the right side cover. Then remove the right side
cover. Turn the pulley until the drum can be locked in the
position whereby the blade installation bolts face upward.

1. Installing blades
CAUTION:
Use only Makita socket wrench provided to tighten
•
the blade installation bolts. The use of any other
socket wrench may cause overtightening or
insufficient tightening of the bolts, resulting in
severe injury.
For throw away blades only
Provide a flat wood block approximately 300 mm long
and 100 mm wide. Place the blade and the set plate on
the wood block so that the blade locating lug of the set
plate rests in the groove of the blade. Adjust the set plate
so that both ends of the blade protrude approximately 1
mm beyond the end of the set plate. Place the two
magnetic holders on the set plate and push them until the
claw contacts the blade.
