Operation - Makita LS1040FN Instruction Manual

CAUTION:
• When performing left bevel cuts, flip the fence over to
the left position as shown in Fig. 24. Otherwise, it will
contact the blade or a part of the tool, causing possible
serious injury to the operator.
Vertical vise (Fig. 25)
The vertical vise can be installed in two positions on
either the left or right side of the guide fence or the holder
assembly (optional accessory). Insert the vise rod into
the hole in the guide fence or the holder assembly and
tighten the screw to secure the vise rod.
Position the vise arm according to the thickness and
shape of the workpiece and secure the vise arm by
tightening the screw. If the screw to secure the vise arm
contacts the guide fence, install the screw on the
opposite side of vise arm. Make sure that no part of the
tool contacts the vise when lowering the handle all the
way. If some part contacts the vise, re-position the vise.
Press the workpiece flat against the guide fence and the
turn base. Position the workpiece at the desired cutting
position and secure it firmly by tightening the vise knob.
CAUTION:
• The workpiece must be secured firmly against the turn
base and guide fence with the vise during all
operations.
Horizontal vise (optional accessory) (Fig. 26)
The horizontal vise can be installed on either the left or
right side of the base. When performing 15° or greater
miter cuts, install the horizontal vise on the side opposite
the direction in which the turn base is to be turned. By
turning the vise knob counterclockwise, the screw is
released and the vise shaft can be moved rapidly in and
out. By turning the vise knob clockwise, the screw
remains secured. To grip the workpiece, turn the vise
knob gently clockwise until the projection reaches its
topmost position, then fasten securely. If the vise knob is
forced in or pulled out while being turned clockwise, the
projection may stop at an angle. In this case, turn the
vise knob back counterclockwise until the screw is
released, before turning again gently clockwise.
The maximum width of the workpiece which can be
secured by the horizontal vise is 130 mm.
CAUTION:
• Grip the workpiece only when the projection is at the
topmost position. Failure to do so may result in
insufficient securing of the workpiece. This could cause
the workpiece to be thrown, cause damage to the blade
or cause the loss of control, which can result in
PERSONAL INJURY.
Holders and holder assembly
(optional accessories) (Fig. 27)
The holders and the holder assembly can be installed on
either side as a convenient means of supporting
workpieces horizontally. Install them as shown in Fig. 27.
Then tighten the screws firmly to secure the holders and
the holder assembly.
When cutting long workpieces, use the holder-rod
assembly (optional accessory). It consists of two holder
assemblies and two rods 12. (Fig. 28)
CAUTION:
• Always support long workpieces level with the top
surface of the turn base for accurate cuts and to
prevent dangerous loss of control of the tool.

OPERATION

CAUTION:
• Before use, be sure to release the handle from the
lowered position by pulling the stopper pin.
• Make sure the blade is not contacting the workpiece,
etc. before the switch is turned on.
• Do not apply excessive pressure on the handle when
cutting. Too much force may result in overload of the
motor and/or decreased cutting efficiency. Push down
handle with only as much force as is necessary for
smooth cutting and without significant decrease in
blade speed.
• Gently press down the handle to perform the cut. If the
handle is pressed down with force or if lateral force is
applied, the blade will vibrate and leave a mark (saw
mark) in the workpiece and the precision of the cut will
be impaired.
• Do not release the saw head uncontrolled from the fully
down position. Uncontrolled saw head may hit you and
it will result in personal injury.
Press cutting (Fig. 29)
Secure the workpiece with the vise. Switch on the tool
without the blade making any contact and wait until the
blade attains full speed before lowering. Then gently
lower the handle to the fully lowered position to cut the
workpiece. When the cut is completed, switch off the tool
and WAIT UNTIL THE BLADE HAS COME TO A
COMPLETE STOP before returning the blade to its fully
elevated position.
Miter cutting
Refer to the previously covered "Adjusting the miter
angle".
Bevel cut (Fig. 30)
Loosen the lever and tilt the saw blade to set the bevel
angle (Refer to the previously covered "Adjusting the
bevel angle"). Be sure to retighten the lever firmly to
secure the selected bevel angle safely. Secure the
workpiece with a vise. Switch on the tool without the
blade making any contact and wait until the blade attains
full speed. Then gently lower the handle to the fully
lowered position while applying pressure in parallel with
the blade. When the cut is completed, switch off the tool
and WAIT UNTIL THE BLADE HAS COME TO A
COMPLETE STOP before returning the blade to its fully
elevated position.
CAUTION:
• Always be sure that the blade will move down to bevel
direction during a bevel cut. Keep hands out of path of
saw blade.
• During a bevel cut, it may create a condition whereby
the piece cut off will come to rest against the side of the
blade. If the blade is raised while the blade is still
rotating, this piece may be caught by the blade,
causing fragments to be scattered which is dangerous.
The blade should be raised ONLY after the blade has
come to a complete stop.
• When pressing the handle down, apply pressure
parallel to the blade. If the pressure is not parallel to the
blade during a cut, the angle of the blade might be
shifted and the precision of the cut will be impaired.
• Always set the sub-fence to the left position when
performing left bevel cuts.
