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
\RXGRLW,I\RXIHHODQ\XQFHUWDLQW\VWRSDQG¿QGDVDIHUDSSURDFKWRWKHDFWLRQ,I\RX¶UHVWLOOXQFHUWDLQDVNIRUDGYLFH
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.

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.

tective equipment such as safety glasses and safety boots and any other equipment required by
plant regulations.

0.7
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 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

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.

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:
x Rotary switch mounted in electrical control cabinet door and inter-locked with door
x Lever switch mounted in separate box mounted on the machine
x 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
INSTALLATION
Upon delivery of your new S-20/23A 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

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 starting the bandsaw, or cutting any material, the operator should be familiar with all operations and
controls as well as the basic cutting theory described below. The saw is equipped with a 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

price of high-technology blades. Variable pitch, bi-metal blades (like the 4/6 or ¾ bi-metal blade supplied with
the machine) 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

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 – Maintenance and Trouble Shooting)
2. Generous coolant application is essential with most materials. A high quality and well-mixed coolant will

Front Vise – This selector switch has three positions, OPEN, NEUTRAL, and CLOSE
This switch must be in NEUTRAL before the hydraulic system can be
started.
In OPEN, the front (saw) vise will open all the way, or until the switch is
released.
In HOLD, the vise will stay where it is, and will not move freely, although it

Head – This selector switch has three positions, UP, HOLD, and DOWN.
This switch must be in NEUTRAL before the hydraulic system can be started.
In UP, the head will rise until it reaches the head up limit, set by means of the
PLC Interface.
In HOLD, the head will stay still, although it may creep down, but at a rate less
than 0.005 inch per minute.
In DOWN, the head will descend until it reaches the head down position. The
speed of descent is controlled by the Head Feed Rate and Head Force controls.

CYCLE IS ON is displayed on the operator interface panel.
In Auto Mode or Single Cut Mode, pushing this button starts the
cycle.
After a cycle has been started, it may be put into Pause by press-
ing the Cycle Start / Pause button and message JOB IS PAUSED
– TO RESUME PRESS CYCLE is displayed on the operator inter-
face panel. Pressing the button again causes the cycle to resume.
In Pause, all machine motions will stop, except blade will continue
to run.
Emergency Stop – This red mushroom head pushbutton stops the blade and hydraulic
pump motors. All machine motions will stop.
Both vises will hold their positions, but clamping force will begin to
fall off. Consequently, long workpieces should always be supported
so that they will not fall if vise clamping force is removed.
The PLC Interface will also be turned off, and any cycle in process
will end. The Emergency Stop is a latching pushbutton and must be
pulled out to permit restarting the machine.
Shuttle Vise - This selector switch has three positions, OPEN, NEUTRAL, and CLOSE.
This switch must be in NEUTRAL before the hydraulic system can be
started.
In OPEN, the auxiliary (shuttle) vise will open all the way, or until the
switch is released.
In HOLD, the vise will stay where it is, and will not move freely, although it

counters enough resistance to stop it.
Blade Start –Agreen pushbutton, illuminated whenever the blade motor is running
To start the blade motor, the Hydraulics must be running, and the head
must not be on the Head Down Limit Switch.
In Single Cut Cycle and Auto Cycle, the PLC Interface Display prompts
Blade Start to enable the cycle to continue.
When restarting after the Emergency Stop Button is pressed, there will be
a 30 second delay from the starting of hydraulics before the blade motor
can be started.
Blade Stop - A black pushbutton.
Pushing this button at any time will stop the blade motor. In any auto
cycle, the blade will stop and head descent will be prevented. Other cycle
motions will continue until the head descent portion of the cycle, at which
point the cycle will wait until the blade is restarted.
HMI KEYS
Function Keys - Provide functions that depend upon the Mode in which the saw is running, as described in

DISPLAY
The display communicates with the operator through the 8 different screens shown in the Screen Map on page
In addition there are the following special screens
Start-up screens – actually a group of screens that display in rapid sequence at start-up.
PLC Parameter Screen – entered only by password to permit fundamental changes to the way in which the
machine operates.
Index Cycle Types
Depending on the part length, the Sequencer selects between two different types of indexing.
Single Indexing is used if part length is less than one, maximum shuttle length.
1. The shuttle retracts to the length of one part, plus kerf allowance.
2. Shuttle Vise closes.
3. Front Vise opens.
4. Shuttle advances to Home position.
5. Front Vise closes.
6. Simultaneously:
a. Head descends to down position, cutting part.
b. Shuttle Vise opens and Shuttle retracts to the length of one part, plus kerf allowance, and
Shuttle Vise closes.
7. Head rises to up limit.
8. Steps 3 – 7 repeat until required parts are cut, except Shuttle stays at Home position during last cut.
Multi Indexing is used if part length is greater than maximum shuttle length, but less than 220”.
1. The shuttle retracts fully.
2. Shuttle Vise closes.
3. Front Vise opens.
4. Shuttle advances to Home position.
5. Front Vise closes.
6. Shuttle Vise opens.
7. Shuttle retracts.
8. Steps 2-7 will repeat until part length plus kerf is reached, after when the front vise will close for the cut.
9. Simultaneously:
a. Head descends to down position, cutting part.
b. Shuttle Vise opens and Shuttle retracts fully, and Shuttle Vise closes.
10. Head rises to up limit.
11.Steps 3 – 7 repeat until required parts are cut, except Shuttle stays at Home position during last cut.
With two Index Cycle types, when required number of parts is cut: the cycle stops
Hydraulic pump and blade motors shut down the PLC remains powered, but returns to Manual Mode
The sequencer controller provides the operator with the ability to operate in three modes:
Manual Mode – Permits the operator to control all machine functions using the panel mounted selector switch-
es and pushbuttons, as well as Operator Interface Function Keys.
Single Cut Mode – Permits the operator to enter a part length, and then advance and cut a single part auto-
matically.
