To reset the chip auger on a Hyd-Mech H-14A bandsaw, you must first lock out the machine power according to your company’s lock-out procedures. This is necessary because the chip auger may start unexpectedly if a jam is cleared while the machine is powered. Once the power is safely locked out, clear the jam manually. After the jam is cleared and the area is safe, restore power to resume operation.

In almost all jurisdictions, it is required that owners of industrial equipment establish and post lock-out pro- cedures.
SECTION 1 – INSTALLATION Upon delivery of you r new H-14A saw, it is imperative that a thorough inspection be undertaken to check for any damage that could have been sustained during shipping. Special attention should be paid to the electrical and hydraulic systems to check for damaged cords and hoses or for fluid leaks.
• Coolant tank emptied. The H-14A may be lifted from the front with a forklift which has a capacity of 4500 lbs (2040 Kg) and a fork length of 72” (1830mm). Lifting chains may be used as an alternative if used in the manner described below: Lifting chains are fastened to 1 - 21⁄4”...
4. Ground rod to be connected to ground terminal in control enclosure using insulated 8-gauge stranded copper wire. 5. 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.
SECTION 2 - OPERATING INSTRUCTIONS This section has been prepared to give the operator the ability to set up the saw for most cutting situations. Before cutting any material, the operator should be familiar with all operations and controls as well as the basic cutting theory described below.
START-UP The H-14A 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 can not overstress the importance of familiarizing yourself with the controls of the H-14A prior to starting the machine.
PLC 100 CONTROL SYSTEM NOTE: This instruction manual is applicable to the H-14A equipped with a MITSUBISHI PLC. OPERATION OVERVIEW The PLC is a programmable logic controller which allows the operator to run the machine in both manual and automatic modes.
DISPLAY WINDOW BLADE SPEED (SFM) IN SURFACE FEET (METERS) PER MINUTE and SHUTTLE VISE (LTH) POSITION PLC FUNCTION KEYS NUMERIC KEY PAD CURSOR KEYS ENTER KEY ACTIVATING THE PLC Position the head, fixed vise, and shuttle vise switches to the NEUTRAL (center) positions. If any of these switches are not in the NEUTRAL position, the hydraulics will not start.

AUTO / MAN MODE - This key will toggle between MAN and AUTO modes. Auto mode cannot be accessed unless the front vise is closed. - Also used to stop an automatic job in progress by switching to MANUAL mode. UNLABELED - The function of theses keys is displayed directly above them.
SINGLE PART CYCLE OPERATION In MAN mode, the PLC allows the operator to initiate a “Single Part Cycle “ to cut one piece at a desired length. To accom- plish this, follow the procedure below. 1. A trim cut should be made before initiating the “Single Part Cycle” operation. 2.

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 the same material and shape. In AUTO mode, press the key below the word “QUE” on the display and the display window will appear as shown.
Feed Force Knob Used to set Feed Force Limit (counterclockwise rotation to increase and clockwise rotation to decrease). Fast Approach Lever Depress for fast head descent. Feed Rate Knob Used to set Feed Rate (counterclockwise rotation to increase and clockwise rotation to decrease).

by each tooth, and it is used in STEPS 3 and 4. In Example #1, for an 8” (200 mm) diameter solid, Effective Mate- rial Width is 8” (200mm). STEP 2, SET FEED FORCE LIMIT The Feed Force Limit is the maximum amount of force with which the head is allowed to push the blade into the work-piece.
Page 27
STEP 4, DETERMINE OPTIMUM BLADE SPEED, V (ft/min) (m/min) The relationship between optimum blade speed and effective material width for vari- ous materials is represented on the graph shown. The graph shows that as effective material width gets wider or as material gets harder, lower blade speeds are recommended.
Page 28
For Example #1, it is known from Step 3 that optimum blade pitch is 2/3, and from Step 4 that blade speed, is 200 ft/min (60mm/min). From the Graph on the left, the FEED RATE is determined in the following way: - On the horizontal axis (blade speed axis), find 200 ft/min(60mm/min).

COOLANT FLOW The main coolant control is found on the control panel. WASH: Coolant flows any time the machine is under power, permitting wash down with spray nozzle without running ma- chine. OFF: No coolant flow. ON: The coolant flows only when the blade is running or when the blade is running and the head is descending. This is selectable via the PLC parameters.
Head up limit trip plate Head up limit switch Head down limit switch Head down limit switch plate HEAD UP and DOWN LIMIT SETTING The head up limit is used to restrict the distance the head travels for each stroke. It can be adjusted at any time by moving the switch trip plate to any position on the vertical bar.
SECTION 3 - MAINTENANCE & TROUBLESHOOTING Switch off before beginning work. • The emergency switch, which is used to turn the hydraulics off, should not be the only means of shutting the power off before cleaning or performing maintenance to the machine. The main power disconnect should be switched off and locked.

10. Check the blade brush adjustment to be sure the blade is being cleaned properly. Blade Tension Slider Assembly DRIVE WHEEL TRACKING (Refer to gearbox illustra- tion) Release blade tension before adjusting. Loosening bolts “A” and turning in set screws “C” by equal amounts will move the blade OFF the wheel.
BLADE BRUSH ADJUSTMENT The H-14A leaves the factory with the blade brush adjusted for maximum life of the brush. This setting places the ends of the blade brush wires so as to contact the blade at the bottom of the blade gullets. The plastic drive wheel that is driven by the drive wheel face should be held against the blade face with the minimum force that is necessary.
