FOREWORD
Put Safety First!
This Safety Section contains important information to help you work safely with your machine and describes the dangers
inherent in our machines. Some of these dangers are obvious, while others are less evident.
It really is important to PUT SAFETY FIRST. Make it a habit to consider the hazards associated with any action BEFORE
you do it. If you feel any uncertainty, stop and nd a safer approach to the action. If you’re still uncertain, ask for advice
from your supervisor.
The SAFETY FIRST approach is particularly necessary when you do something new, or different, and most people in-
stinctively recognize this, although impatience may still cause them to take unnecessary risks.
Danger also lurks in the routine task that we have done over and over. Here, familiarity, boredom, or tiredness may lull us
into unthinking, automatic repetition. Be alert for this, and when you feel it happening, stop and take stock of your situa-
tion. Review the safety hazards associated with what you are doing. That should get your brain working again.
Certainly production is important, but if you think you’re too busy to put safety rst, think how much production you’ll lose if
you get hurt.
You owe it to yourself, your family, and your co-workers to PUT SAFETY FIRST.

or non-compliance with the Safety and Operating Instructions contained in this Manual.

0.5
RESPONSIBILITIES OF THE OWNER
Organization of work
This Operation and Maintenance Manual must always be kept near the machine so that it is accessible to
all concerned.
The general, statutory and other legal regulations on accident prevention and environmental protection
must also be observed, in addition to the Manual material. The operators and maintenance personnel
must be instructed accordingly. This obligation also includes the handling of dangerous substances and
the provision and use of personal protective equipment.
Choice and qualication of personnel
Ensure that work on the machine is only carried out by reliable persons who have been appropriately
trained for such work.
Training
Everyone working on or with the machine must be duly trained with regard to the correct use of the ma-
chine, the correct use of safety equipment, the foreseeable dangers that may arise during operation of the
machine, and the safety precautions to be taken.
In addition, the personnel must be instructed to check all safety devices at regular intervals.
Dene responsibilities
Clearly dene exactly who is responsible for operating, setting-up, servicing and repairing the machine.
Dene the responsibilities of the machine operator and authorize him to refuse any instructions by third
parties if they run contrary to the machine’s safety.
Persons being trained on the machine may only work on or with the machine under the constant supervi-
sion of an experienced operator. Observe the minimum age limits required by law.

0.6
Condition of Machine and Workplace
Ensure that the machine and its safety equipment is kept in good working order.
Ensure that the work area is well lit, and protected from the elements, such as rain, snow, abrasive dust,
and extremes of temperature.
Ensure that the machine is installed with sufcient clearance around it for the safe loading and unloading
of work pieces.
RESPONSIBILITIES OF THE OPERATOR AND MAINTENANCE PERSONNEL
Safety equipment
All machines are delivered with safety equipment that must not be removed or bypassed during operation.
The correct functioning of safety equipment on the machine must be checked:
• at the start of every shift.
• after maintenance and repair work
• when starting for the rst time, and after prolonged shutdowns
Emergency Stop Button ( E-Stops)
Always be aware of the location of the Emergency Stop Button(s). Do not allow material or objects to
block your access to an Emergency Stop.
Damage
If any changes capable of impairing safety are observed in the machine or its operation, such as damage,
malfunctions, or irregularities, then appropriate steps must be taken immediately, the machine switched
off, locked-out, and the fault reported to the responsible person.
Safe operation
The machine may only be operated when in good working order and when all protective equipment is in
place and operational.
Keep a safe distance from all moving parts – especially the blade and vises
Stock should not be loaded onto the saw if the blade is running
Long and heavy stock should always be properly supported in front of and behind the saw.
Faults
The machine must be switched off and locked-out before starting to remedy any faults.
Safety hazard labels
Safety hazard labels, and other instructional labels on the machine must be observed. They must be
clearly visible and legible at all times. If they become damaged they must be replaced.
Clothing, jewellery, protective equipment
Personnel operating or working on the machine must not wear un-restrained long hair, loose-

0.7
tting clothes and dangling jewellery.
When operating or working on the machine, always wear suitable, ofcially tested personal pro-
tective equipment such as safety glasses and safety boots and any other equipment required by
plant regulations.
Gloves
Experience has shown that careless use of gloves around machinery is a major factor in serious
hand injuries.
Gloves should not be worn when operating or adjusting the machine, except:
Wear protective gloves when handling bandsaw blades at blade changes.
Gloves may be worn when handling work pieces, only if the machine is in Manual Mode
and the bandsaw blade is not running.
If the machine is running in Auto Mode, and only if the cut parts are greater than 24
inches long, it may be possible to safely wear gloves for handling the cut parts, but the
wearer of the gloves must never put his hands near the blade for any reason. If the cut
parts are less than 24 inches long, it is required to arrange their automatic ow into a
parts bucket or other suitable arrangement to avoid the necessity to pick them off the
machine by hand.
Hearing protection
Ear protection must be worn whenever necessary.
The level and duration of noise emission requiring hearing protection depends upon the national
regulations in the country in which the machine is being used.
The actual level of noise emission by band sawing machines depends upon work piece size,
shape and material, blade type, blade speed and feed rate.
The only practical course of action is to measure the actual noise emission levels for the type
of work that is typically done. With reference to national standards, decide upon the necessary
hearing protection required.
In the absence of such measurements, it is advisable for anyone exposed to long periods of
moderate to loud noise to wear hearing protection. It is important to understand that hearing loss
is gradual and easily goes un-noticed until it is serious and irreversible.
Workplace
A clear working area without any obstructions is essential for safe operation of the machine. The oor
must be level and clean, without any build-up of chips, off-cuts, coolant, or hydraulic oil.
The workplace must be well lit, and protected from the elements, such as rain, snow, abrasive dust, and
extremes of temperature
Nothing may ever be placed on, or leaned against the machine, with the obvious exception of the work
piece on the table and conveyor of the machine.
Master Disconnect
Lock-out the machine before undertaking any maintenance or repair work on it. ‘Lock-out’ refers switching
off the master electrical disconnect switch, and locking it out so that it cannot be switched on again
without authorization.
On Hyd-Mech machines the Master Disconnect Switch will be of one of three types:
• Rotary switch mounted in electrical control cabinet door and inter-locked with door

0.8
• Lever switch mounted in separate box mounted on the machine
• Supply disconnect switch supplied by user at installation and usually wall-mounted within sight of
the machine, depending upon local regulations.
In almost all jurisdictions, it is required that owners of industrial equipment establish and post lock-out pro-
cedures. Know and use the lock-out procedures of your company or organization.
Residual Risks
The machine is still not completely de-energized if an electrical cabinet door type switch is
locked-out.
The line side of the disconnect switch itself remains energized.
Variable speed blade drives store dangerous voltage in their capacitors, and this requires time to
dissipate. After locking out power, wait 3 minutes before beginning to work on machine electrical
circuits.
If compressed air is supplied to the machine to power a mist lubrication system or other devices,
it should be disconnected, and any stored air pressure released before working on the machine.
The weight of individual machine components represents stored potential energy that can be
released if they fall when disconnected. Secure these components with adequate hoisting gear
before disassembly.

1.1
SECTION 1 – INSTALLATION
Upon delivery of you r new H-14P 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 uid leaks. In the event of damage caused during shipping, contact your carrier
to le a damage claim.
SAFETY PRECAUTIONS
The H-14P has been designed to give years of reliable service. It is essential that operators be alerted to the safe opera-
tion of this saw, and the practices to avoid that could lead to injury. The following safety rules are at a minimum for the
safe installation, operation and maintenance of the saw. Take every precaution for the protection of operators and mainte-
nance personnel.
• POWER HOOK-UPS AND REPAIRS SHOULD BE ATTEMPTED ONLY BY QUALIFIED TRADESMEN.
• THE SAW SHOULD BE LOCATED IN AN AREA WITH SUFFICIENT ROOM TO SAFELY LOAD STOCK INTO
THE SAW. SECURE THE SAW TO THE FLOOR.
• THE AREA AROUND THE SAW SHOULD BE MAINTAINED IN A CLEAN AND TIDY CONDITION TO AVOID
OBSTACLES OPERATORS COULD TRIP OVER.
• THE H-14P SHOULD ONLY BE OPERATED ACCORDING TO THE SPECIFICATIONS OF THE SAW. AVOID
UNSAFE USAGE PRACTICES.
OPERATOR:
• THE SAW SHOULD NEVER BE OPERATED UNLESS ALL GUARDS AND DOORS ARE IN PLACE AND
CLOSED.
• KEEP A SAFE DISTANCE FROM ALL MOVING PARTS ESPECIALLY THE BLADE AND VISES.
• LOOSE CLOTHING AND GLOVES SHOULD NEVER BE WORN WHILE OPERATING THE SAW. COVER LONG
HAIR.
• STOCK SHOULD NOT BE LOADED ONTO THE SAW IF THE BLADE IS RUNNING.
• LONG AND HEAVY STOCK SHOULD ALWAYS BE PROPERLY SUPPORTED IN FRONT OF AND BEHIND THE
SAW.
• NEVER ATTEMPT TO DISLODGE OR MOVE STOCK WHILE THE BLADE IS MOVING. TAKE THE TIME TO
STOP THE SAW BLADE, REMOVE OBSTRUCTIONS AND RESTART THE BLADE.
• WEAR EYE PROTECTION
• MAINTAIN PROPER ADJUSTMENT OF THE BLADE TENSION, BLADE GUIDES, AND THRUST BEARINGS.
No modications to the machine are permitted without prior approval from HYD·MECH. Any modications should only be
undertaken by trained personnel.

1.2
LIFTING AND SHIPPING
This machine is designed to be lifted in one fully assembled piece. In order to lift the ma-
chine it needs to be in the following condition:
• Saw head in its bottom position.
• Coolant tank emptied.
The H-14P may be lifted from the front with a forklift which has a capacity of 5000 lbs 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 - 2¼” diameter steel bar inserted in the base and 2 lugs at the front base.
FOUNDATION LEVELING AND ANCHORING
Machine location should be carefully selected. A at concrete oor area
should be chosen. It should have enough free space surrounding the
machine to enable free access for safe operation and maintenance.
The machine should be leveled in both directions, i.e. along and across
its infeed conveyor especially when machine is to be inserted into a
larger conveyor system. Six leveling screws are provided, one in each
corner of the machine base as shown below. Steel plates are to be
placed under each screw to prevent their sinking into the concrete oor.
In cases when the machine is to be anchored permanently, anchoring
holes are provided. They are located next to the leveling screws.
NOTE:
In some cases leveling the saw infeed and auxiliary conveyors with a slight slope towards the blade is recommended. This
will prevent coolant from running down the raw stock. (This is especially true when cutting tubing or bundles)
GENERAL INFORMATION
This machine has been built to the customers requirements, however, if any voltage changes are required, please consult
Hyd·Mech service department before implementing any changes.
NOTE:
1. The PLC is equipped with a lithium battery to keep the program stored while the power is shut down. The battery
will need to be replaced every 3 to 5 years, depending on usage. A visual warning will be displayed on the inter-
face when the battery drains to a certain level. Batteries can be purchased through your Hyd·Mech Distributor.
2. If the machine is equipped with an inverter, do not turn the disconnect on for 3 three minutes after disconnect has
been shut off. Cycling power sooner than 3 minuets will result in damage to the Variable Frequency Drive.
EARTH GROUNDING PROCEDURE
1. Customer to provide and install a ground rod approx. 60 (15mm) diameter, copper clad steel, to be driven no less
than 8’ (2.5m) into the ground, no more than 10’ (3m) away from control enclosure.
2. Ground rod to be connected to customer’s in plant ground system. This connection shall be made directly at the
ground rod (If applicable).
3. It is desirable that the overall resistance to ground measured at the ground rod does not exceed 3 ohms. Cus-
tomer is advised to consult local power company for further information on grounding.

1.3
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. Also PLC and Interface units should have their own ground
conductors connected to one of the main ground terminals.
6. Properly functioning ground system will;
• Provide safety for personnel.
• Ensure correct operation of electrical/electronic devices.
• Prevent damage to electrical/electronic apparatus.
• Help dissipate lightning strokes.
• Divert stray radio frequency (RF) energy from electronic/control equipment.
WIRING CONNECTIONS
After the machine is leveled and anchored the necessary power hook-up needs to be performed.
In order to provide a safe operation as well as to prevent potential damage to the machine, only qualied personnel
should be allowed to do the work.
The rst two areas that need to be checked are:
• There are no signs of shipping damage to electrical conduits, cords or hydraulic hoses.
• Hydraulic oil level is between the upper and lower lines on the level gauge.
As supplied, the machine is set to run on the three phase voltage as indicated on the serial plate and voltage label.
Power connection to the machine is made to the main disconnect box with the Ll, L2,L3 and Ground terminals. The dis-
connect box is located at the drive side of the machine.
During the initial hook-up it is very important to check that the phase order is correct. This is indicated by the hydraulic
pressure gauge registering a pressure rise and the blade running in a counterclockwise direction. If the hydraulics do not
register an immediate pressure rise,
- shut the hydraulics off and change the phase order.
HYDRAULIC OIL AND CUTTING FLUID
As shipped the saw oil tank is lled with Arco - Duro AW46 hydraulic oil. If you want to change the hydraulic oil or the
brand of oil, see HYDRAULIC MAINTENANCE.
No cutting uid is supplied with the machine. There are two types of coolant available:
• oil based; dilute in 1:10 ratio (one part of concentrated coolant and 10 parts of water)
• -synthetic; dilute as recommended by manufacturer.

2.1
SECTION 2 - OPERATION INSTRUCTIONS
Blade speed adjuster.
This section has been prepared to give the operator the ability to set up the saw for most cutting situations. The saw is
equipped with variable blade speed control and hydraulic feed control, as well as an extensive door chart to guide the
operator to the correct setting of these controls.
BLADE BASICS
Technology is rapidly changing all aspects of production machining. Metal cutoff is no exception. The advances made
in the bandsaw blade industry have denitely brought down the cost per cut, despite the three fold higher price of high
technology blades. Variable pitch, bi-metal blades (like the 4/6 or 3/4 bi-metal blade supplied with the M-16/20) last much
longer, cut faster, and more accurately than conventional carbon steel blades. In order to take advantage of the superiority
of bi-metal blades, it is critical to properly “break-in” a new blade. This is accomplished by taking two or three cuts through
solid four or ve inch diameter mild steel at an extremely slow feed rate. (It is also advisable to utilize a slow blade speed.)
These two or three slow cuts sufciently lap (polish) the new blade so that it does not snag the material being cut. Proper
break-in will alleviate blade vibration; improve surface nish, accuracy, and blade life.
After “break-in”, the following six points must be closely monitored to ensure long blade life:
1. Proper blade tension should be maintained. (See Section 3, Blade Changing)
2. Generous coolant application is essential with most materials. A high quality and well mixed coolant will extend
blade life, and also increase cutting rate and quality. On those materials where coolant is undesirable for cutting,
a slight coolant ow or periodic oiling of the blade is necessary to prevent the blade from being scored by the
carbide guides.
3. The stock being cut must be securely clamped in the vises.
4. The proper feed force should be chosen.
5. The proper blade speed must be selected.
6. The proper feed rate must be applied.
VARIABLE SPEED CONTROL
Blade speed can be adjusted innitely between 50 to 350 SFM (Surface Feet/Minute) (15.3 to 107 meters/min). The blade
speed is controlled with dial on the control panel.

2.2
Operator Control Console
TOP ROW
THE CONTROL CONSOLE
START-UP
The H-14/18/22 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 H-14/18/22 prior to starting the machine.
NOTES:
1. ALL SWITCHES MUST BE IN THE CENTER NEUTRAL POSITION TO START THE MACHINE!
2. WHEN STARTING THE MACHINE FOR THE FIRST TIME MAKE SURE THAT BLADE IS MOVING IN A
COUNTERCLOCKWISE DIRECTION, AND THAT THE HYDRAULIC PRESSURE IS 700 PSI (H-14),1000
PSI (H-18) AND 1100 PSI (H-22). IF THERE IS NO IMMEDIATE PRESSURE, SHUT THE SAW DOWN AND
CHANGE THE PHASE ORDER AS STATED IN SECTION 1 .
FRONT VISE - 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. With
the switch in the HOLD position, the vise will stay where it is and will not move freely
although it will not resist a large force indenitely without creeping. In CLOSE, the
vise will close all the way, or until it encounters enough resistance to stop it.
HEAD CONTROL - This switch has three positions: UP, HOLD and DOWN. The switch is inactive unless
the PLC is in manual mode. In the UP position, the head will rise until it trips the head
up limit which is adjustable via the PLC. In the HOLD position the head will stay still.
In the DOWN position the head will descend until it reaches the bottom of the stroke.
The speed of descent is controlled by the Head Feed and Head Force Limit controls.
BLADE START - The blade can be started only when the hydraulics are running in either manual or
auto mode.
NOTE: In automatic Mode the head will not descend until the blade has been started, which the PLC will
prompt the operator to do so.

2.3
COOLANT - This switch has three positions, ON, OFF, and AUTO. In the ON position, the
coolant system will operate when there is power to the machine, this allows
using the wash gun to clean the machine. In the OFF position, the coolant
system is inactive. In the AUTO position the coolant system will only run when
the head is descending. This minimizes coolant carry over on the stock.
BLADE SPEED -
This dial will increase or decrease the speed at any time while the blade is
running.
BLADE STOP -
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.
STOP - This mushroom button stops the blade and hydraulic motors. Both vises will
hold their position but, pressure will begin to fall off. Long pieces of work
should always be supported so they will not become loose over time and fall
while the machine is shut down.
CENTER ROW
HYDRAULIC START - To start the hydraulic system, the switches for the head and both vises
must be in the “NEUTRAL” position. The “HYDRAULIC START” but-
ton must be depressed and held in momentarily until the PLC display
becomes active.
CYCLE START / PAUSE - This button starts the cutting cycles and will stay illuminated white until
the cycles are completed. The PLC control system will prompt you
to start the blade if it is not running. The machine will then begin the
automatic cycle until completed when it will shut itself off. The current
cycle can be PAUSED by pressing this button at any time during a
cycle and restarted by pressing it again.
WORK LAMP - This switch has two positions, OFF and ON.
LASER GUIDE - This option switch has two positions, OFF and ON.

MITSUBISHI PLC CONTROL SYSTEM
NOTE:
This instruction manual is applicable to the M16P, M20P, H14P to H32P machines equipped with a Mitsubishi PLC, c/w
feed rate display, manufactured with serial numbers ending with or higher than _ _ _ _ 0899.
OPERATION OVERVIEW
The PLC is a programmable logic 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 console and the
PLC function buttons.
In automatic mode, the machine will cycle for one cut and be ready for the next cut when nished.
NOTE:
If an emergency situation arises during any operations, use the large red mushroom “EMERGENCY STOP” button located
on the control panel to shut down the machine.
ACTIVATING THE PLC
Position the head and vise switches to the NEUTRAL (center) positions. If either of these switches are not in the NEU-
TRAL position, the hydraulics will not start. The PLC control will become active when the HYDRAULIC START button is
depressed and “held in” momentarily. First, the PLC’s current revision number will be shown on the display window. The
AUTO/MAN indicator light will be off and all MANUAL controls are enabled.
