3. INSTALLATION : 3.1 Moving and Lifting : Unpack your machine carefully , and use a crane or forklift to set it in position. If a crane is used to lift the machine attach the lifting cable carefully to the machine as shown in the fig 2. If forklift is used then fig 3. Sufficient space should be left around the machine to allow safe handling of materials , and inspection and maintenance operation.
3.2 Foundation layout and set-up : 3.2.1 Foundation : The foundation should be constructed of reinforced concrete and must be level and flat. After the proper leveling position has been obtained , anchor the machine with anchor bolts. The position of anchor bolts and floor dimensions are shown in fig 4: □ ○ Contact portion with floor Position of anchor bolts Fig. 4 ※ All leveling bolts should support the weight of the machine evenly .
3.2.2 Leveling : The production accuracy of all precision machinery depends on the accuracy which the machine is installed . Manufacturing tolerance of the machine can only be guaranteed if the machine is firmly and properly installed . Once the machine is lowered on the prepared foundation . Machinist levels should be used alternately on the vice slide plates and the work feed table , and adjust the left-and-right and fore-and-aft level of the machine with leveling bolt .
3.2.3 Cleaning and oiling : After the machine has been placed in position , thoroughly remove its rust preventive coating using a suitable cleaning solvent and then apply a coat of machine oil . To clean the machine , Kerosene is preferable to gasoline . It does not evaperate and level dried slushy compound on finished surfaces. Rags are better than waste as they leave no lint or strings. The machine as received by you. has been completely drained of all oil. Before any attempt is made to run it ....
4. OPERATION (Type 1) 4.1 Control Panel (1) PNC Control Panel Cutting Piece Counter – This counter is used to preset the number of cuts required on the automatic operation. When the counter reaches the preset number, the machine stops automatically . To activate the counter, preset the counter switch with number at least “1”. Clear – This key is used to clear the counted number cut already and to have new number input available.
(2) PILOT LAMP -- This light will comes on when the power supply is on. (3) EMERGENCY STOP -- This switch is used for emergency case to stop the machine only. Turn this switch clockwise makes power source on. When this switch is pressed, all machine's operation stop immediately. (4) HYDRAULIC "ON" BUTTON -- When this button is depressed, the hydraulic pump motor operates. (5) POWER SWITCH OFF -- This switch is used for turning off the power by depressing it.

4.2 OPERATING PREPARATION There are several steps will be taken before start the machine. (1) CHOOSE PROPER SAW BLADE : Select the saw blade best suited to the workpiece to be cut, Size and shape of the workpiece , and type of material should all be sonsidered when selecting the saw blade to be used . There is a refernce chart in chapter 9 which can help you to select the right saw blade and cutting conditions .
(7) ADJUST THE FEED RATE : Select suitable feed rate for the workpiece to be cut. This varies according to the size and shape of the workpiece, type of material , and what type of saw blade is being used. As a guide hard materias, wide workpiece or structural sections and tubing have to be cut at a slower rate that mild steel bar. As concerns the saw blade , bigh speed steel is better than carbon steel, and bi-metal alloy is better than high speed steel.
4.4 AUTOMATIC OPERATION : Having finished all the procedures described above in (2) Operating Preparation ,and with the workpiece to be cut placed in the vise of the machine , but NOT under the saw blade. (1) Turn the AUTO-MANUAL selector to manual. In control panel – The front vise clamp the workpiece when turn switch NO.(8) right and press button NO.(6) 1.5sec in the same time. Then the front vise hold the workpiece after the lamp NO.(6A) light. (2) Turn the AUTO-MANUAL selector to auto.
ADDITION 1: Amplifying Valve ( Optional ) (1.) The outlines and hydraulic circuits: (2.) SET-UP A. The hydraulic pressure indicated in line
should be kept in constant during the whole stroke of the lifting cylinder, i.e. Between the very top and bottom position of the swinging saw frame. we use springs inside of lifting cylinder to balance/compensate the pressure changes (pressure varies due to saw frame swinging up and down ) in line .
B. Re-zeroing knob "a" & "b" on the amplifying valve: For zeroing knob "a", there is a hydraulic pressure gauge as drawing needed, Please plug it onto the outlet on the amplifying valve. Pressure read at line
as the primary pressure............pressure
Pressure read at amplifying valve as the secondary pressure..

5.2 Oiling and Lubricant The operator should be responsible for the proper lubrication of the machine. The grade and quality of lubricant are given in the lubrication chart below : Oil Lubrication chart Lubricating Point Lubricant Quantity Oiling Frequency 1. Blade Tension Device DAPHNE FLUID 32T Few Twice a year 2. Drive Wheel Bearing Grease Few Thrice a year 3. Guide Slides Shell Tonna 33 Few Oil daily 4. Transmission Gear Box DAPHNE GEAR LUBE 320 Few Twice a year 5.
5.3 OTHERS VARIABLES WHICH AFFECT BANDSAW BLADE LIFE 1. The Operator - The operator is the most important variable at any test. He can make or break any test and often has a qreat deal of influence over whose bandsaw blades are used. He can also be a good source of information on what is going on, competitive situations, relationships with manufacturers or distributors, etc. Don't ignore the operator. 2 .
12. Machine Condition-Whether a machine is old or new, and whether well maintained or not contributes to how well it runs and how long the band last. The better shape a machine is in, the better the bands will run. Poor machines ruin bandsaw blades. 13. Proper Vises - The work must be properly held. Side vises and top vises, if necessary, should be in good shape and able to firmly hold the work. Anything that moves will strip teeth. 14. Guides - The guides must support the band well while in the cut.
