NOTICE:
install it on the spindle with its protrusion facing away
from the blade. If the flange is installed incorrectly, the
flange will rub against the machine.
Return the blade guard and center cover to its original
position. Then tighten the hex bolt clockwise to secure
the center cover. Unlock the stopper pin to release
carriage from the raised position. Lower the handle to
make sure that the blade guard moves properly. Make
sure shaft lock has released spindle before making cut.
Before mounting the blade onto
WARNING:
the spindle, always be sure that the correct ring
for the blade's arbor hole you intend to use is
installed between the inner and the outer flanges.
Use of the incorrect arbor hole ring may result in the
improper mounting of the blade causing blade move-
ment and severe vibration resulting in possible loss
of control during operation and in serious personal
injury.
Connecting a vacuum cleaner
When you wish to perform clean cutting operation, con-
nect a Makita vacuum cleaner to the dust nozzle using
a front cuff 24 (optional accessory).

Dust bag
The use of the dust bag makes cutting operations clean
and dust collection easy. To attach the dust bag, remove
the dust extraction hose on the tool and connect the
dust bag.
► Fig.35: 1. Dust extraction hose 2. Dust bag
When the dust bag is about half full, remove the dust
bag from the tool and pull the fastener out. Empty
the dust bag of its contents, tapping it lightly so as to
remove particles adhering to the insides which might
hamper further collection.

Securing workpiece

WARNING:
secure the workpiece correctly with the proper
type of vise or crown molding stoppers. Failure to
do so may result in serious personal injury and cause
damage to the tool and/or the workpiece.
WARNING:
raise the blade until it has come to a complete
stop. The raising of a coasting blade may result in
serious personal injury and damage to the workpiece.
WARNING:
is longer than the support base of the saw, the
material should be supported the entire length
beyond the support base and at the same height
to keep the material level. Proper workpiece support
will help avoid blade pinch and possible kickback
which may result in serious personal injury. Do not
rely solely on the vertical vise and/or horizontal vise
to secure the workpiece. Thin material tends to sag.
Support workpiece over its entire length to avoid
blade pinch and possible KICKBACK.

Guide fences
WARNING:
sure that the upper fence is secured firmly.
WARNING:
that no part of the tool, especially the blade, con-
tacts the upper and lower fences when fully low-
ering and raising the handle in any position and
while moving the carriage through its full range
of travel. If the tool or blade makes contact with
the fence this may result in kickback or unexpected
movement of the material and serious personal injury.
