FOREWORD
Put Safety First!
This Safety Section contains important information to help you work safely with your machine and describes the dangers inherent to bandsaws. 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.

BASIC RULES
Intended Use
Exclusion of Misuse
Liability
Our machines are designed and built in line with the state of the art, and specically in accordance with
American National Standards Institute Standard B11.10 Safety Requirements for Metal Sawing Machines. However, all machines may endanger the safety of their users and/or third parties, and be damaged,
or damage other property, if they are operated incorrectly, used beyond their specied capacity, or for purposes other than those specied in this Manual.
Misuse includes, for example:
Sawing hazardous materials such as magnesium or lead.
Sawing work pieces which exceed the maximum workload appearing in the Specications.
Operating the machine without all original safety equipment and guards.
The machine may only be operated:
When it is in good working order, and
When the operator has read and understood the Safety and Operating Instructions Sections of the Manual, 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.
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 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.
0.3
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 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 are 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.
0.4
Clothing, jewellery, protective equipment
Personnel operating or working on the machine must not wear un-restrained long hair, loose-tting
clothes and dangling jewellery.
When operating or working on the machine, always wear suitable, ofcially tested personal protective
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.
0.5
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 the operator interface console.
• 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.
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.
0.6
PINCH POINT
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.
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 labelled pinch points, whenever the machine is running. Machine vises can exert great force and cause severe injury. Keep hands clear of vises and work piece when vises are opened or closed. Be aware that vise closing or opening may result in potentially dangerous work piece 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.

The 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.
Machine should be leveled in both directions i.e. along and across its in-feed 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 plus one in the hydraulic cabinet. Steel plates are to be placed under each screw to prevent their sinking into the concrete oor. In cases where 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 in-feed and auxiliary con­veyor with a slight slope towards blade is recommended. This will prevent coolant from running down the raw stock. (This is especially true when cutting tubing or bundles).
BARFEED INSTALLATION
1. Prepare the machine base for mating with the barfeed. Place shims into position and place a bead of silicone on the surfaces shown below.
Shim

MACHINE GUARD INSTALLATION
15. Position the three pieces of the safety guard around the barfeed. The idler side guard is connected to the ma­chine column by a hex bolt. The drive side guard is connected to the control box by a hex bolt. The rear guard is connected to the rear of the barfeed frame with two hex bolts.
A pulley is mounted on a bracket and attached to each rear corner of the safety guard.
1.8
16. Fasten the trip wire control box to the safety guard and complete the wire connections (see schematics). The box is attached to the mounting plate with four socket head cap screws. The plate is mounted to the safety guard
with two hex bolts.
17. Attach the eyebolt to the idler side column. Fasten the wire rope to the spring and then proceed to feed it through the eyebolts and pulleys along the guardrail. Loop the other end of the wire rope around the eyebolt of the trip wire control box. Tighten or loosen the idler side column eyebolt to adjust the tension on the wire rope. The switch cannot be activated if there is not enough tension on the wire rope.
1.9
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 qualied personnel should make the connections.
BEFORE START-UP THE FOLLOWING TWO POINTS SHOULD BE CHECKED:
1. Signs of damage that may have occurred during shipping to the electrical cables and the hydraulic hoses.
2. The hydraulic oil level is between the upper and lower lines on the level gauge.
As supplied, the machine is set to run on three phase voltage as indicated on the serial plate and voltage label.
Power connection to the machine is made to L1, L2, L3 and Ground terminals in the main electrical box found beside the conveyor on the drive side. For machines equipped with a variable frequency drive unit, an earth ground is also recom­mended.
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 counter clockwise direction. If the hydraulics do not register an immediate pressure rise, shut the hydraulics off and change the phase order.
ATTENTION: Running the hydraulics “backwards” can damage the hydraulic pump.
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. Cus­tomer 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 AWG stranded copper wire.
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.
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.
HYDRAULIC OIL AND CUTTING FLUID
The H18A_H22A 120 bandsaw is supplied with Texaco Rando HD46 hydraulic oil. If it is necessary to change the oil to a different brand see the HYDRAULIC SECTION for equivalent grade oil.
No cutting uid 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 the manufacturer.
