3.2 Preparation for installation
1. LEVELING: It is important to install the machine so that the rear most portion of
the main body table, feed table and roller bed is slightly raised. This prevents
cutting fluid from flowing backward along the material to be cut, especially long
material, and draining on the floor.
See Figure 3.3
Shim section B thicker than section A by 6mm. Shim section D thicker than section
E by 14mm. Horizontally, the table should be level or a little lower on the right.
FIGURE 3.3
If the table is higher on the right, recovery of the cutting oil will be slowed. The
height of the roller table, which is factory-adjusted, need not be re-adjusted. Be sure
the roller table is on the same level as the upper face of the feed table. Use a
straight edge to determine this. The roller face should be level with the feed table or
up to 0.12mm higher.
After the leveling is complete, check to make sure none of the steel sheets fail to
touch the floor due to overload.
REMOVING BRACKET FOR TRANSPORTATION: This bracket must be removed
before operating machine. Keep the bracket for use in moving the machine in the
future.

4.7 How to install bundle attachments
How to use the bundle cutting attachments
WARINING!!!!!
Never install the bundle attachments while the machine is in
operation. This machine electricity must be locked out before
installing bundle attachments.
WARNING!!!!!
Keep fingers clear of vise, personal injury could occur.
This multi-vise is used when bundle cutting is performed. To perform bundle cutting,
proceed as follows:
1. Install the stud bolts on the front and rear vises and position the multi-vise on
the front and rear vises.
2. Connect the multi-vise hoses to their quick connectors at the front and rear vise
cylinders.
3. Attach the bundle cutting fence to the work tray. The fence is designed to
prevent the cut pieces from spreading out across the work tray. Adjust the width
of the fence so that it equals the width of the bundle.
12/10/07 Model LE13A Text 19
4. Set the switch to bundle cutting (item 13 pages 11).
CORRECT
INCORRECT
5. Position the work piece for bundle cutting.
Allowable clamping width: 7 inches (180mm)
6. Roughly align the center of the multi-vise cylinders with the center of the work
pieces to be cut and tighten the lock nuts.
7. Turn the multi-vise handles so that there is 1/4” of clearance between the work
retaining plate and the material.
8. For subsequent operations, refer to the instructions for manual operation and
automatic operation, and perform the bundle cutting.
EXAMPLE:
BLADE BREAK IN OPERATION
When a new saw blade is used, be sure to first break in the blade before using it for
actual extended operation. Failure to break in the blade will shorten the life of the
blade and result in less than optimum efficiency. To break in the blade, proceed as
follows:
1. Lengthen the time required for cutting 2-3 times that of normal.
12/10/07 Model LE13A Text 20
2. The break-in operation can be considered sufficient if all unusual noises
or metallic sounds have been eliminated. (For instance, to completely
break in the blade, a minimum of five complete cuts of a 200mm (7.9 in)
diameter work piece will be required.)
3. After the break-in operation has been completed, return the blades speed
and descending speed to their normal settings
