Do not wear gloves, neckties, loose clothing or jewelry while operating machine. 3. Keep fingers out of path of the blade. 4. Do not remove jammed or cut-off pieces until blade had completely stopped. 5.
Location of Safety Labels 1.2 1 3 2 4 1 7 5 6 be alert to the potential personal injury. SAFETY you see this symbol on your saw, Follow recommended precautions and safe operating practices. Carefully read all safety messages in these instructions and on your saw safety signs. Keep safety labels in good condition.
2.2 Machine Life The intended life limit of this machine is ten years under normal operating conditions and with good maintenance. The intended life of this machine is calculated by: 8 hours x 5 days x 52 weeks x 10 years = 20,800 hours. 2.3 Intended Use The LE10A is an automatic hydraulic band saw machine. It is designed and constructed for metal sawing only. It is not intended to cut other materials for example: meat, wood, stone, plastic, Mg and analogous materials.

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.
This red bracket must be removed before the electrical is connected. Warning!!!! Figure 3.4 Failure to remove this bracket could cause damage to the machine and void the warranty. INITIAL OILING: Clean the machine thoroughly. Be sure anti-corrosion additives applied to sliding parts are removed with cleaning oil. When making a test run refer to the instructions on 8-1 for proper oiling. Be sure the cutting fluid is full before operating, since it is usually drained before packing.
CAUTION!!!!! THE GROUND WIRE MUST BE CONNECTED; FAILURE TO CONNECT THE GROUND WIRE CAN DAMAGE THE MACHINE AND VOID THE WARRANTY. Next, make sure the emergency stop button is not activated and that item 4 on page 11 is to the right. Now press the LIFT button (see picture item 6 on page 11); lifting starts in one or two seconds after the emergency button is released, the head continues in the up direction as long as the button is held down.
SECTION 4 4.1 Control Panel Description 12 13 14 15 11 1 10 2 3 4 5 6 7 8 9 1. POWER LIGHT This light will come on when the circuit breaker is ON. 2. EMERGENCY STOP BUTTON When this button is depressed, all machine operations will stop. 3. BLADE DRIVE BUTTON When this button is depressed, the saw blade motor, cutting fluid pump and the chip removal system will begin to operate and the saw head begins to descend.
4. AUTO-MANUAL SELECTOR (AUTO). For Continuous cutting, turn this selector to To individually operate each function, turn this selector to the hand picture (MANUAL). 5. QUICK APPROACH BUTTON When this button is pressed the head will move in the downward position until the quick approach arm touches the material. 6. RAISE BUTTON When this button is pressed the blade motor stops and the saw head moves in the upward position. When the button is released the head will stop moving. 7.
For bundle cutting, set this switch to the multiple picture, so that the rear vise remains at the forward limit position. For single cutting, set this switch to the single picture, so that the rear vise stays at the backward limit position. NOTE: When the switch is set for bundle cutting, the blade will not start unless the rear vise is at the forward limit position. 14.
Warning!!!!! Never change the blade with the power on. f. Remove the blade safety cover. g. Open both the drive wheel and idle wheel covers. h. Turn both the left and right insert lock levers counter clockwise to loosen the inserts. i. Turn the blade tension selector to “LOOSEN” to move the driven wheel toward the idle wheel, this will loosen the blade. j. Remove the band saw blade. k. Place the saw blade onto both the drive and idle wheels. l.
i. Carefully place the work piece onto the work feed table so that is extends approximately 2.5” (60mm) beyond the rear vise. 2. Determine the proper position of the work piece for cutting. j. Turn the vise clamp selector to “rear vise open”. k. Manually move the rear vise until it pushes against the work piece. Then engage the pawl with the rack. l. Turn the vise clamp selector to “front vise open”, so that the work piece is securely clamped with the rear vise. m.
When the blade drive button is pressed, the cutting fluid pump begins to operate causing the cutting fluid to flow out the coolant lines. Adjust the cutting fluid flow with the fluid controls so that the proper amount of fluid will flow from the blade inserts, the quick approach and the wire brush case. The flow of cutting fluid should be adjusted, depending upon the material. Saw chips which are fine and curve require an increase in the amount of cutting fluid.
4.5 Automatic operation instructions AUTOMATIC OPERATION 1. Cut the edge of the work piece by using the same procedures as those described under the Manual Operation Section above. 2. Press the raise button to raise the saw blade until the quick approach feeler is approximately 10mm (0.4 in) above the work piece. 3. Turn the vise clamp selector to open the front vise. 4. Press the rear vise forward button until the work piece moves forward to the required cutting position. 5.
c. Set the feed times counter at 2. d. Now the material will be pushed forward two times, each time moving the material forward 15.75 inches. NOTE: 1. The cutting length preset device is factory adjusted to compensate for the set width of the saw blade. 2. When the feeding times preset counter is not in use, set it a 1. 3. The feeding times preset counter is capable of feeding the work piece nine times, up to a maximum cutting length of 212.5 inches (5400mm). 8.
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.
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. 2. The break-in operation can be considered sufficient if all unusual noises or metallic sounds have been eliminated.
