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.

when it is in good working order, and
when the operator has read and understood the Safety and Operating Instructions Sections of the Manu-
al, and
when all operations and procedures are in compliance with this Manual.
Hyd-Mech Group cannot accept any liability for personal injury or property damage due to operator errors
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.

0.7
Clothing, jewelry, protective equipment
Personnel operating or working on the machine must not wear un-restrained long hair, loose-
tting clothes and dangling jewelry.
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 unnoticed until it is serious and irreversible.

0.8
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
• 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.

0.9
SAFETY HAZARD LABELS
The safety hazard labels attached to your machine represent important safety information to help you avoid personal injury
or death.
All supervisors, operators, and maintenance personnel must locate and understand the safety information associated with
each hazard label prior to operating or servicing the machine.
The safety hazard labels shown below are located at various positions on the machine to indicate possible safety hazards.
The location, and re-order part number of all the safety labels associated with this particular model of bandsaw are indicated
at the end of this section of the manual. It is important to replace any safety hazard label that becomes damaged or illegible.
HAZARDOUS VOLTAGE INSIDE
Contact with high voltage may cause death or serious injury. Never perform maintenance on, or near, electrical components
until the machine’s electrical power source has been disconnected. Lock-out
power in accordance with your company’s lock-out procedures before any such
maintenance. The “Stop” or “Emergency Stop” push button does not disconnect
the machine’s power supply. Hazardous voltage is still present in the machines
electrical circuits.
The machine’s Electrical Disconnect Switch does disconnect voltage from the
machine’s circuits, however hazardous voltage is still present inside the main
electrical cabinet, on the infeed (line) side of the main fuses. Therefore keep hands
and tools away from the infeed side of the control panel main fuses. If these fuses
need to be replaced, use a fuse puller.
Allow three minutes after locking-out power before opening any electrical enclosures. Your machine may be equipped with a
variable frequency drive that stores high voltage within its capacitors. Three minutes will allow sufcient time for this voltage
to safely discharge.
Never spray coolant directly at electrical components or cabinets.
MOVING BANDSAW BLADE WILL CUT
Do NOT operate with guard removed.
Do NOT place hands or ngers near moving bandsaw blade.
For blade changing, always follow the proper Blade Changing Procedure, as given in
Section 3 of this manual.

0.10
PINCH POINT
Machine parts may move without warning, either because the machine is
operating automatically, or because another person initiates the motion. Keep
hands clear of all labeled pinch points, whenever the machine is running.
Machine vises can exert great force and cause severe injury. Keep hands
clear of vises and workpiece when vises are opened or closed. Be aware
that vise closing or opening may result in potentially dangerous workpiece
movement. Be aware also that the opening motion of a vise may create
potential pinch points.
MOVING PARTS CAN CRUSH AND CUT
Keep hands clear of chip auger. Lock-out power in accordance with your
company’s lock-out procedures before attempting to clear a jam in the chip
auger.
Be aware that the chip auger may start unexpectedly, either because the
machine is operating automatically, or because another person initiates the
motion.
If the chip auger is stalled because of a jam, it may start without warning when
the jam is cleared, unless the machine power is locked out.

SECTION 1 - INSTALLATION
Upon delivery of your new H14A 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 H14A has been designed to give years of reliable service. It is essential that operators be alerted to the safe
operation 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
maintenance 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 H14A 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 MACHINE
This machine is to be lifted in one, fully assembled piece. In order to lift the machine it needs to be in the following
condition:
• Saw head in the down position
• Shuttle vise fully forward
• Coolant tank emptied
The H14A may be lifted from the FRONT with a forklift, which has a minimum capacity of 4500 lbs (2040 kg) and a fork
length of 72” (1830mm).
The machine is shipped on sections of 4 x 4 tubing. The tubing blocks should be removed prior to locating the machine
onto the shop oor.
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 (from side to side & from front to back), using a level on the machine out-feed table. Six leveling
screws are provided (these are shipped in the coolant tank), and should be installed. One at each front and rear corner
of the machine base, one inside the power pack enclosure, and one at the base of the drive side post. Steel plates are
provided (also shipped in the coolant tank) 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 screw holes.
NOTE:
In some cases leveling the saw in-feed and conveyor 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).
Using a level on the machine out-feed table, level machine front to back and side to side
Inside Power Pack Drive Side Post

1.3
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 in the electrical control panel, located at the rear of the machine. The power ca-
ble can be routed through the supplied hole at the rear of the machine, and connections made to L1, L2, L3, and ground
terminals. Proper strain relief should be used on the incoming power cable.
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,
-Disconnect the power- and change the phase order.
L1, L2, L3, & Ground Connections
Inside the electrical control enclosure
ATTENTION: Running the hydraulics “backwards” can damage the hydraulic pump.

1.4
HYDRAULIC OIL AND CUTTING FLUID
As shipped the saw oil tank is lled with Texaco Rando HD 46 hydraulic oil. If you want to change the hydraulic oil or the
brand of oil, see HYDRAULIC MAINTENANCE section.
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.
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.
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.
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.
