2.1 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. 2.2 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. This machine was shipped with oil in it.
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.

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.
. Vise shut off switch. When this switch is off the counter will not work. 14. FEEDING-TIMES PRESET COUNTER When a cutting length of more than 23” (600mm) is required, preset the required number of feeds on this counter. The counter is capable of being set to the maximum of nine feeds. 9*15.74=141.66 (9 x 400mm = 3600mm) 15. WORKING LIGHT Turn this knob to the left to have the work light on, turn the knob to the right to have the work light off. 16.
4.2 Blade change 1. Select the saw blade best suited for the work piece to be cut. Size and shape of the work piece and type of material should all be considered when selecting the saw blade to be used. 2. Saw blade change. Warning!!!!! Always wear gloves, safety glasses and other protective equipment to prevent injury when changing the saw blade. The power must be locked out before changing the saw blade. a. Turn on the main power on the left side of the machine. b.
4. Properly position the blade guide according to the diameter (or the width) of the work piece to be cut. a. Pull the left insert lock lever down to loosen the insert. b. Loosen the lock lever of the blade guide, and manually move the blade guide and align the indicator of the blade guide with the scale of the guide bar, depending upon the size of the work piece. c. After adjusting the blade guide position tighten the lock lever of the blade guide. d. Push the insert lock lever up to tighten the insert.
u. After properly adjusting the position of the work piece, turn the vise clamp selector to “back vise open”, so that the work piece is securely clamped with the front vise. v. Adjust the blade speed to the proper speed section 4.4 w. Turn on the coolant by turning the coolant switch. The flow of cutting fluid should be adjusted, depending upon the material. x. When the blade drive button is pressed, the cutting fluid pump begins to operate causing the cutting fluid to flow out the coolant lines.
4.5 Blade speed change 3. Adjust the saw blade speed. c. There is a handle just to the right of the motor, when loosened the motor can be moved up and down. Move the motor up and move the belt to the desired speed. d. It is necessary to properly adjust the saw blade speed, depending upon the material and shape of the work piece to be cut. e. The blade drive uses a V-Belt: A-47 (60 Hz) and A-48 (50 Hz). Blade speeds are 27, 40, 54, 68 and 80m/min 4.
NOTE: 1. When setting the cutting length, be sure to turn the hand wheel clockwise past the desired length, then turn it counter clock wise to the desired length to prevent error due to the backlash. c. Tighten the hand-wheel lock screw Hand wheel 4. If the required cutting length exceeds the maximum cutting length of 23.6 inches (600mm), feed the work piece as many times as necessary, using the feed times preset counter (item 14 page 11). For example: if a cutting length of 31.
6. Turn the auto-manual selector to AUTO and press the blade drive button. The blade will run and the automatic operation will begin. 7. After the required number of cuts have been completed, the saw blade will stop in the lower position and all machine operations will stop. NOTE: i. During automatic operation, shifting the auto-manual selector to MANUAL will cause the saw blade to stop in the lower position, after completion of the cutting operation on which the selector was shifted.
4. Set the switch to bundle cutting (item 13 pages 11). 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.
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 4.
