Operator should keep a safe distance from all moving parts especially the blade and operating vises. Long hair, loose clothing or gloves should not be worn while operating the V-18 APC. The area around the machine should be kept clean and tidy.
LIFTING AND SHIPPING To lift a crated V-18APC II bandsaw, a forklift can be used. Minimum capacity of 7500 LB. at 48” from the mast is required as well as 6’ forks. To lift the bandsaw with a crane, position the head to 65°. Then insert 2” diameter shafts through the lifting holes in the machine base.
4. Insert the four studs into their respective holes and fasten the panel using the supplied 3/8-16 unc nuts and washers. 5. Level the panel and fully tighten the nuts to lock assembly in place. 6. Place excess cord and hose length neatly inside base the enclosure and replace the base front cover. WARNING! PANEL WEIGHT 150 LB.
the dilution ratio is 1:10, one part concentrate to ten parts water. For synthetic cutting fluids dilution, if required, should be done to the specifications as recommended by the manufacturer. WIRING CONNECTIONS After the machine is leveled and anchored the necessary power hook-up needs to be performed. In order to provide safe operation as well as to prevent potential damage to the machine, only qualified personnel should make the connections.

An additional point to check is ensuring continuity of ground within control enclosure. Start with main power entrance ground terminal where internal ground conductors should originate and connect to, DIN terminal strip, control transformer and the lid of control enclosure. Also PLC and Interface units should have their own ground conductors connected to one of the main ground terminals.
SECTION 2, OPERATING INSTRUCTIONS START-UP The V-18A PC II control console has been designed to simplify the operation of the saw, to give the operator the ability to stop any function at any time, and to be able to control all the functions remotely. We cannot overstress the importance of familiarizing yourself with the controls of the V-18A PC II prior to start- ing the machine.
OPERATOR PANEL SWITCHES TOP ROW SAW VISE - (vise between the shuttle & outfeed vises) This switch has three positions, OPEN, HOLD and CLOSE. With the switch held in the OPEN position the vise will open all the way or until the switch is released.
Page 15
BLADE STOP BUTTON - Stops the blade. If the blade is stopped during a cycle, the cycle will continue but will not let the head descend until the blade is started EMERGENCY STOP - This mushroom button stops the blade and hydraulic motors. Both vises will hold their position but pressure will begin to fall off.
OPERATION OVERVIEW The PLC is a programmable length controller which allows the operator to run the machine in both manual and automatic modes. In manual mode, all functions can be operated by using a combination of selector switches on the control con- sole and the PLC function buttons.
FUNCTION BUTTON DESCRIPTION On the dual function buttons, if a green indicator light is illuminated, it means that the function printed in green on the top of the button is enabled. A red light indicates the function printed in red at the bottom of that button is enabled. MANUAL MODE •...
MANUAL MODE • After entering an angle value, pressing F2 will cause the screen to read “TO INTIATE MOVE- MENT TO XX.X DEGREES PRESS CYCLE START”. Upon pressing “CYCLE START” the head will swing to the programmed angle. AUTO MODE Used to scroll up through job information.
length movement. 8. When the cut is completed, the head will retract, the blade will stop and the display window will reset for the next cut. 9. To cut another job, repeat steps 1 through step 7. NOTE: To cut multiple pieces, switch to AUTO and follow the automatic procedures. AUTOMATIC OPERATION To enter AUTO MODE, the saw vise switch must be in the closed position.
Page 20
PICK LIST SCREEN 1. Immediately after entering the AUTO mode, the PICK LIST screen will be displayed with the cursor located at “A1 of JOB #1”. Both the ENTER button or the cursor key can be used to move through this screen.
WORKING WITH A QUEUE The purpose of a QUEUE is to allow the operator to run several jobs (max of 5) in series if they are of like material. To run a QUEUE, it is necessary to program in all job values as is done with programming a single job.
VARIABLE SPEED CONTROL Blade speed can be adjusted infinitely between 65 to 385 SFM (20 to 117m/min). Adjustment should be made only when the blade is running. Clockwise rotation of dial on the control panel increases blade speed while counter clockwise rotation decreases blade speed. HYDRAULIC FEED CONTROL The Hydraulic Feed Control is located to the top of the control panel.
CHART EXAMPLE #1 We will use the parameters chart to set up the saw for cutting 8” (200mm) Diameter #1045 Carbon Steel. STEP 1, DETERMINE EFFECTIVE MATERIAL WIDTH - W (inches) or (mm) Effective material width, W (in.) for most common shapes of materials, is the widest solid part of the material to be in contact with blade during cutting.
Page 24
slower on wide material because the small gullets between the teeth will get packed with chips before they get across and out of the cut. Too coarse a blade must be fed slower because it has fewer teeth cutting and there is a limit to the depth of a cut taken by each tooth.
STEP 5, DETERMINE FEED RATE SETTING, FR (in/min) (mm/min). FEED RATE is the vertical speed at which the blade descends through the work- piece. The FEED RATE Knob controls FEED RATE of the blade descent in the range 0 to 15 in/min (380mm/min). The FEED RATE should be adjusted only in one direc- tion (from “O”...
STEP 3 Optimum blade pitch (TPI): 3/4 T. P. I. Actual blade pitch on the saw: 4/6 T. P. I. STEP 4 Optimum blade speed for 4 1/2” effective 225 ft/min (70 m/min) material width Blade speed reduced by hardness factor: 225 ft/min X .60 = 135 ft/min (70 m/min x .60 = 42 m/min) STEP 5 Feed Rate for 3/4 TPI blade:...
CHIP CONVEYOR The chips generated while sawing can be removed from the bottom of the machine with the help of the optional chip conveyor. Rotation of the chip conveyor crank will operate the conveyor in the direction of rotation of the crank.
SECTION 3, MAINTENANCE AND TROUBLESHOOTING BLADE CHANGING We cannot overstress the safety precautions which should be followed during this operation. Safety glasses, gloves as well as a long sleeve shirt should be worn. The hydraulics should be off at all times when the opera- tor has his/her hands in contact with the blade.

Drive wheel mounting bolts and track- ing bolt assemblies.
If the brush gets worn to approximately 70% of its original 3” diameter it should be replaced. A brush may be purchased from your HYD-MECH dealer. Blade brush & adjusting screw (circled).
HEAD FORWARD LIMIT SETTING The Head Forward Limit is factory set and under normal operating condi- tions should not need to be reset. TO SET LIMIT: If adjustment is necessary, the Head Forward Limit is an assembly on the vise cylinder rod. Loosen the set screw that allows setting of the limit switch actuator, and adjust according to your needs.
HYDRAULIC MAINTENANCE There are four items of routine maintenance associated with the hy- draulic system of the V-18 II. With proper maintenance the hydraulic system of the V-18 should provide years of reliable service. 1. OIL FILTER - Ten micron filtration of the hydraulic oil is pro- vided by a spin on type filter mounted on the tank return line as shown below.
TROUBLE SHOOTING GUIDE Most problems which may occur have one of the relatively simple solutions which appear in this section. If the solution is not found here, contact the Hyd·Mech Distributor from whom you purchased your bandsaw. They have trained field service personnel who will be able to rectify the problem. NOTES: 1.

To view the parameters: Start the machine and, in manual mode, enter the parameter screen by pressing the PARAMETERS. Type the password which can be obtained from HYD-MECH and press ENTER. The parameter screen will appear. MITSUBISHI PLC 500 PARAMETER SCREEN (V18APC SHOWN)
NOTE: For M16/20A and older V18APC (Before but not including serial # K0399163), the parameter screen is slightly different. There will be only one Angle Calibration enable line (Reads: ANG CLB “ENTER” OFF), and only one Total Measured Angle line (Reads: TTL MEAS ANG: 90.07). MITSUBISHI PLC 500 PARAMETERS To navigate through the parameters use the green arrow keys to move the cursor.
3. At this point the procedure is done and the line should read - LTH CLB “ENTER” OFF. The cycle light will still be flashing. At any point after the procedure has started, move the cursor to ACT LTH line, type in the desired value (original parameter) and press ENTER.
cursor on this line press ENTER key and line will read - ANG CLB “ENTER” ON, and cycle light will be flash- ing. Start the blade and the procedure will execute; On V18APC: The head will swing slowly to 45 L, and then will come forward for a cut. It will retract, then swing slowly to 45 R, come forward for a cut, and then retract.
