Securing Workpiece - Makita LS1216 Instruction Manual

To remove the blade, use the socket wrench to loosen
the hex bolt holding the center cover by turning it coun-
terclockwise. Raise the blade guard and center cover.
Press the shaft lock to lock the spindle and use the
socket wrench to loosen the hex bolt clockwise. Then
remove the hex bolt, outer flange and blade.
NOTE:
• If the inner flange is removed be sure to 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.
WARNING:
• Before mounting the blade onto 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 movement and severe vibra-
tion resulting in possible loss of control during opera-
tion and in serious personal injury.
To install the blade, mount it carefully onto the spindle,
making sure that the direction of the arrow on the surface
of the blade matches the direction of the arrow on the
blade case.
Install the outer flange and hex bolt, and then use the
socket wrench to tighten the hex bolt (left-handed)
securely counterclockwise while pressing the shaft lock.
Return the blade guard and center cover to its original
position. Then tighten the hex bolt clockwise to secure
the center cover. Release the handle from the raised
position by pulling the stopper pin. Lower the handle to
make sure that the blade guard moves properly. Make
sure the shaft lock has released spindle before making
cut.
Dust bag
(Fig. 38)
The use of the dust bag makes cutting operations
cleaner and dust collection easier. To attach the dust
bag, fit it onto the dust nozzle.
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 par-
ticles adhering to the insides which might hamper further
collection.
NOTE:
• If you connect a vacuum cleaner to your saw, cleaner
operations can be performed.
Dust box (optional accessory)
Insert the dust box into the dust nozzle.
Empty the dust box when necessary.
To empty the dust box, open the cover by pushing the
button and dispose of the sawdust. Return the cover to
the original position and lock it in place. Dust box can
easily be removed by pulling it out while turning it near
the dust nozzle on the tool.
NOTE:
• If you connect a Makita vacuum cleaner to this tool,
cleaner operations can be performed.
NOTICE:
• Empty the dust box before collected sawdust level
reaches the cylinder section.

Securing workpiece

WARNING:
• It is extremely important to always secure the work-
piece 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.
• After a cutting operation do not 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.
• When cutting a workpiece that 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 seri-
ous 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 KICK-
BACK. (Fig. 42)
Guide fence (SLIDING FENCES which are upper
and lower fences) adjustment
WARNING:
• Before operating the tool, make sure that the upper and
lower fences are secured firmly.
• Before bevel-cutting, make sure that no part of the
tool, especially the blade, contacts the upper and
lower fences when fully lowering and raising the
handle in any position and while moving the car-
riage 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.
The lower fences can be moved inward and outward by
loosening the clamping screws. (Fig. 43)
A red indicating area will appear as the lower fences are
moved inward and will disappear as the lower fences are
moved outward.
The upper fences can be removed or moved inward and
outward by loosening the levers. (Fig. 44)
In case of bevel-cutting, adjust the lower and upper fence
positions to be as close to the blade as practical to pro-
vide maximum workpiece support, and make sure that no
part of the tool, especially the blade, contacts the lower
and upper fences when lowering and raising the handle
fully at any position and pulling or pushing the carriage all
the way at the lowest position. (Fig. 45)
Before cutting operations, make a dry run with the saw
turned off and unplugged, then check clearance between
fences and moving parts.
Before cutting operations, firmly secure lower fences by
tightening the clamping screws and upper fences by
tightening the levers.
When bevel-cutting operations are complete, don't forget
to return the upper fences to the original position and
return it.
Vertical vise (Fig. 46)
The vertical vise can be installed in two positions on
either the left or right side of the base. Insert the vise rod
into the hole in the base.
