Operation - Makita LS1440 Instruction Manual

OPERATION

CAUTION:
• Before use, be sure to release the handle from
the lowered position by turning the handle latch
to the released position.
• Make sure the blade is not contacting the work-
piece, 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.
Press cutting
► Fig.26
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".
Cutting aluminum extrusion
► Fig.27: 1. Horizontal vise 2. Spacer block
3. Aluminum extrusion 4. Guide fence
When securing aluminum extrusions, use spacer
blocks or pieces of scrap as shown in the figure to
prevent deformation of the aluminum. Use a cut-
ting lubricant when cutting the aluminum extrusion
to prevent build-up of the aluminum material on
the blade.
CAUTION:
• Never attempt to cut thick or round aluminum
extrusions. Thick aluminum extrusions may
come loose during operation and round alumi-
num extrusions cannot be secured firmly with
this tool.
Wood facing
► Fig.28: 1. Guide fence 2. Wood facing
Use of wood facing helps to assure splinter-free
cuts in workpieces. Attach a wood facing to the
guide fence using the holes in the guide fence.
See the figure concerning the dimensions for a
suggested wood facing.

CAUTION:
• Use straight wood of even thickness as the
wood facing.
• Use screws to attach the wood facing to the
guide fence. The screws should be installed so
that the screw heads are below the surface of
the wood facing.
• When the wood facing is attached, do not turn
the turn base with the handle lowered. The
blade and/or the wood facing will be damaged.
NOTE:
• When the wood facing is attached, the maxi-
mum cutting capacities in width will be reduced
by thickness of the wood facing.
Cutting repetitive lengths
► Fig.29: 1. Set plate 2. Holder 3. Screw
When cutting several pieces of stock to the same
length, ranging from 300 mm to 400 mm, use of
the set plate (optional accessory) will facilitate
more efficient operation. Install the set plate on the
holder (optional accessory) as shown in the figure.
Align the cutting line on your workpiece with either
the left or right side of the groove in the kerf board,
and while holding the workpiece from moving,
move the set plate flush against the end of the
workpiece. Then secure the set plate with the
screw. When the set plate is not used, loosen the
screw and turn the set plate out of the way.
NOTE:
• Use of the holder-rod assembly (optional acces-
sory) allows cutting repetitive lengths up to
2,200 mm approximately.
Carrying tool
► Fig.30: 1. Handle latch
Make sure that the tool is unplugged. Secure the turn
base at right miter angle fully by means of the grip.
Lower the handle fully and lock it in the lowered position
by turning the handle latch to the locked position.
Carry the tool by holding both sides of the tool base
as shown in the figure. If you remove the holders, dust
bag, etc., you can carry the tool more easily.
► Fig.31
CAUTION:
• Always secure all moving portions before carry-
ing the tool.
• Handle latch is for carrying and storage pur-
poses only and not for any cutting operations.
