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 instinctively 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 situation. 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.
0.4
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 qualication 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 machine, 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.
Dene responsibilities
Clearly dene exactly who is responsible for operating, setting-up, servicing and repairing the machine.
Dene 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 supervision of an experienced operator. Observe the minimum age limits required by law.
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 sufcient clearance around it for the safe loading and unloading
of work pieces.
0.5
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 Buttons). 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, 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, ofcially tested personal pro-
tective equipment such as safety glasses and safety boots and any other equipment required by
plant regulations.
0.6
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.
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.
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.
0.7
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 four types:
• Rotary switch mounted in electrical control cabinet door and inter-locked with door
• Rotary switch mounted on the side of electrical control cabinet.
• 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 procedures. 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.
0.8
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 sufcient 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.
0.9
PINCH POINT
Machine parts may move without warning because of another person initiating the motion. Keep hands clear of all labeled
pinch points, whenever the machine is running. Machine vises and bundling can exert great force and cause severe injury.
Keep hands clear of vises and work piece when the vises and bundling are opened or closed. Be aware that vise and
bundling closing or opening may result in potentially dangerous work piece movement. Be aware also that the head swing
either left or right, and the advancement or retraction of the head may create potential pinch points.

SECTION 1 - INSTALLATION
Upon delivery of your new bandsaw, 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, hoses and uid leaks. In the event of damage caused during shipping, contact your carrier to
le a damage claim.
SAFETY PRECAUTIONS
The bandsaw 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 the minimum
necessary 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 BANSAW SHOULD ONLY BE OPERATED ACCORDING TO THE SPECIFICATIONS OF THE SAW. AVOID
UNSAFE USAGE PRACTICES.
• IF AT ANY TIME THE SAW DOES NOT APPEAR TO BE OPERATING PROPERLY IT SHOULD BE STOPPED
IMMEDIATELY AND REPAIRED.
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 BLADE.
• MUST WEAR EYE PROTECTION
• MAINTAIN PROPER ADJUSTMENT OF BLADE TENSION, AND BLADE GUIDES
• HOLD WORK PIECE FIRMLY AGAINST TABLE
• DO NOT REMOVE JAMMED CUTOFF PIECES UNTIL BLADE HAS STOPPED
NO MODIFICATIONS TO THE MACHINE ARE PERMITTED WITHOUT PRIOR APPROVAL FROM HYD-MECH. ANY APPROVED MODIFICATIONS SHOULD ONLY BE UNDERTAKEN BY TRAINED PERSONNEL.
1.1
LIFTING THE S20A WITH A FORK LIFT
S20A
MACHINE WEIGHT: 3600 lbs (1597 Kg)
MINIMUM FORK LENGTH: 48” (1.2mm)
LIFT FROM SIDE ONLY
DAMAGE WILL RESULT!
FORK LIFT INSTRUCTIONS
The S20A is shrink-wrapped and shipped on a pallet. When lifting the pallet with a forklift truck make sure that the load is
rmly balanced. The pallet length dimension is 94" (2388 mm). Minimum fork length of 48" (1219 mm) is recommended to
safely lift the pallet.
Remove the wrapping from around the saw. Complete the inspection for signs of damage. Remove the lag bolts that hold
the saw to the pallet. The larger diameter hole is used for retaining during shipping and for use with concrete oor anchors. The smaller diameter, threaded holes at each corner are used for leveling the saw properly.
The machine should be lifted from the SIDE as shown below. Locate one fork 10” and the other 38” from the front edge of
the machine.
NOTE: DO NOT position the forks to allow contact with the hydraulic cabinet. DAMAGE WILL RESULT!
1.2
FOUNDATION, LEVELLING 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). Six leveling screws
used for securing machine to the pallet during transport, should be installed,
one in each corner of the machine base, as shown below. It might be required
to place steel plates under leveling bolts to prevent their sinking into the con-
crete oor. In cases when the machine is to be anchored permanently, anchoring
holes are provided. They are located next to the leveling screw holes. The larger
diameter hole is used for retaining during shipping and for use with concrete oor
anchors. The smaller diameter threaded hole at each corner, are used for leveling
the saw.
Using a level on the machine out-feed table, level machine front to back and side
to side.
NOTE: In some cases leveling the saw infeed 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).
EARTH GROUNDING PROCEDURE
1. The customer is to provide and install a ground rod approximately .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. The ground rod is 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.
Customer is advised to consult local power company for further information on grounding.
4. The ground rod is to be connected to the ground terminal in the control enclosure using insulated, stranded
copper wire. The wire gauge size is to be determined according to the electrical code of the customers
local electrical authority.
5. An additional point to check is to ensure continuity of all ground within the control enclosure. Start with the main
power entrance ground terminal where the internal ground conductors should originate and then connect to, the
DIN terminal strip, control transformer, and the lid of control enclosure. Also, the PLC and Interface units
should have their own ground conductors connected to one of the main ground terminals.
6. A properly functioning ground system will:
- provide safety for personnel.
- ensure correct operation of electrical/electronic apparatus.
- prevent damage to electrical/electronic apparatus.
- help dissipate lightning strikes.
- divert stray radio frequency (RF) energy from electronic/control equipment.
1.3
POWER WIRING CONNECTIONS
After the machine is levelled and anchored the necessary power hook-up needs to be performed.
Check that there is no sign of shipping damage to the electrical conduits, cords or hydraulic hoses.
As supplied, the machine is set to run on three phase voltage as indicated on the serial plate and voltage label.
Machine voltage is customer specic and should be indicated while ordering the machine. If machine voltage does not
match available power source, contact the factory.
Power connection to the machine is made in the junction box, located on the side of the electrical panel. The power cable
can be routed through the supplied hole in the junction box (ensure correct strain relief is used) and connections made to
terminals L1, L2, L3 and ground terminals. If the machine is equipped with an auto-transformer then the power cable is to
be connected to the fuses located in the junction box.

bandsaw.
HYDRAULIC OIL
The S20A is supplied with Texaco Rando HD46 hydraulic oil. Substitutes should be of the same viscosity hydraulic oil.
CUTTING FLUID
The S20A uses a pump and reservoir to circulate the necessary cutting uid to the blade for maximum blade life. Your saw
blade supplier will be able to provide information to the cutting uid products that are available for your needs.
No cutting uid (coolant) is supplied with the machine. There are two types of coolant available:
- Oil based; dilute 1:10 ratio (one part concentrated coolant to 10 parts water)
- Synthetic; dilute as recommended by manufacturer.

SECTION 2 - OPERATING INSTRUCTIONS
OPERATOR CONTROL PANEL
The operator control panel provides the operator with all the controls necessary to operate the saw after the cutting angle
has been set and the stock has been loaded and secured. All of the electrical functions are operated from the control
panel. For all the functions to work the machine has to be powered up. The Main Disconnect switch, which is located
on the side of control box, has to be in ON (1) position. Emergency Switch has to be released (Rotate Emergency button
45º to release). For the blade to operate the blade guard door has to be completely shut and blade tensioned to the correct setting:
S20A: Minimum tension 2200 lbs. (1000kg) Maximum tension 2650 lbs. (1200kg)
S20A Machine Disconnect Switch
The Machine Disconnect Switch is located on the side on the machine control box. It is a Thermal-magnetic circuit
breaker with under voltage coil and door locking device. The switch consists of three power failure protection sys-
tems. In the event of a power failure, this switch disconnects all the electrical devices, causing the machine to immediately
shut down and prevents it from automatically starting when power is restored. This device also resets the thermal relay
tted to protect against current overloads.
START-UP
We can not overstress the importance of familiarizing yourself with the controls of the bandsaw prior to starting the ma-
chine for the rst time.
NOTE: WHEN STARTING THE BANDSAW FOR THE FIRST TIME MAKE SURE THAT THE PRESSURE IS 440 PSI
(30 BAR) AND THAT THE BLADE IS RUNNING IN A COUNTER CLOCKWISE DIRECTION AS VIEWED FROM THE
OPERATOR CONSOLE.
2.1
CONTROL CONSOLE
The control console is arrayed with a complete set of controls to operate the electrical and hydraulic functions of the saw.
The HMI (Human Machine Interface) consists of all, the electrical controls required to function the saw.
OPERATION CONTROLS
The electrical push buttons on the HMI allow for full manual and semi-automatic operation of the bandsaw. The operation
of each push button is detailed on the following pages.
HYDRAULIC FEED CONTROL
The hydraulic feed controls are located on the left side of the control console and consist of the Feed Force Setting knob,
the Feed Rate knob and the Head Fast Approach lever. These controls allow the operator to control both the Feed Force
Limit and the Feed Rate. See Cutting Parameters Chart information on the following pages.
