Operation - Makita LS1440 Instruction Manual

The vertical vise can be installed in the position on either
the left or right side of the guide fence. Insert the vise rod
into the hole in the guide fence 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.

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
•
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.
1. Press cutting
002159
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.
2. Miter cutting
Refer to the previously covered "Adjusting the miter
angle".
3. Cutting aluminum extrusion

002861
When securing aluminum extrusions, use spacer
blocks or pieces of scrap as shown in the figure to
prevent deformation of the aluminum. Use a cutting
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 aluminum
extrusions cannot be secured firmly with this tool.
4. 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.
