SECTION 1, INSTALLATION
Upon delivery of your new S-23 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, hoses and fluid leaks. In the event of damage caused during
shipping, contact your carrier to file a damage claim.
SAFETY PRECAUTIONS
The S-23 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.

LIFTING THE S-23 with a FORK LIFT
The S-23 is shipped with a shipping pallet attached to the
saw. When lifting the pallet with a forklift truck make sure that
the load is firmly balanced. The following photo shows a lift truck
lifting the saw and pallet from the correct side. The pallet length
dimension is 84". Minimum fork length of 72" is recommended to
safely lift the pallet.
WRAPPED FOR SHIPPING
The S-23 is shrink-wrapped for shipping from our plant.
Remove the wrapping from around the saw. Complete the
inspection for signs of damage. Undo the bolts that hold the
saw to the pallet. Retain these bolts to use for levelling. The
following photo illustrates the floor mounting plates located at
the corners of the saw. The larger diameter hole is used for
retaining during shipping and for use with concrete floor
anchors. The smaller diameter, threaded holes at each corner
are used for levelling the saw properly.

CUTTING FLUID
The S23 uses a pump and reservoir to circulate the necessary cutting fluid to the blade for maximum blade life.
Your saw blade supplier will be able to provide information to the cutting fluid products that are available for your
needs.
No cutting fluid (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.
LEVELLING THE SAW
Use a machinist's level across the vise table
to level the saw. Adjust the level with the levelling
bolts supplied. Consideration should be given to
the flow of the coolant as it returns to the coolant
trough at the vise end of the saw. Levelling to
give a small incline towards this area helps to
ensure the coolant supply returns to the
container.

SPEED ADJUSTOR INSTALLATION
The speed adjustor is packaged seperately for shipping purpose and must be installed prior to connecting the
power supply. Failure to do so will cause a safety hazard. Refer to page 6.3 for installation instructions.
HYDRAULIC OIL
The S-23 is supplied with ISO viscosity grade #22 mineral hydraulic oil in the
Head cylinder. Substitutes must be of the same viscosity in order for the system
to work properly.
The cylinder contains oil in a reservoir that should be topped up to the level
of the filler plug. Add oil to the cylinder only with the Head in the Head Down
position. The head cylinder is a self air-bleeding cylinder with a small port in the
top plate. If excess oil is displaced from this port, the cylinder is working
normally.

Pg 4 S23 2001d
POWER CABLE ROUTING
The main power cable can be routed up through the bottom of the
head frame to the access holes in the end of the control panel. Cable
liquide tight reliefs should be used to secure the cable into the control
panel to ensure there is no movement of the cable when the machine is
operated.
POWER WIRING CONNECTIONS
When the machine has been anchored and levelled the power hook-up is the last installation step. In order to
provide safe operation and to prevent potential damage to the machine, only qualified personnel should make the
electrical connections.
As supplied your new S-23 is set to run on three phase voltage or single phase.The supply voltage of the
machine is displayed on the Serial # Plate and the Voltage Label.
Connection from the Main supply is made to L1, L2, L3, (or L1 & L2 for single phase) and Ground terminals
between the contactor & transformer.
Supply conductors should be rated for the current supplied and should be protected by time delay fusing rated for
the amperage stated on the machine serial plate
CHECK FOR: - Signs of damage to the electrical cables from shipping or installation.
- Correct phase order.The blade should be running counter clockwise.
(If the blade direction is wrong, two lines should be reversed to correct)

Before any material is cut, it is necessary to have good understanding of the basics of cutting metals. Damage
to the blade and the saw it’s self as well as injury to the operator may occur if the saw is not used properly. Refer
to Section I for safety instructions. Following is the necessary information and instruction to operate this machine
properly.
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 definitely brought down the cost per cut, despite the three fold
higher price of the newer technology blades. Variable pitch (see Pg 2.3), bi-metal blades (like the 5/8 or 4/6 bimetal
blade supplied with the S-20 Series II saws) last much longer, cut faster, and more accurately than the
conventional carbon steel blades. In order to take advantage of the superiority of bi-metal blades, it is critical to
property “break-in” a new blade. This is accomplished by taking two or three cuts through solid four or five inch
diameter mild steel at an extremely slow feed rate. These two or three slow cuts sufficiently lap (polish) the new
blade so that it does not snag the material being cut. Proper break-in will alleviate blade vibration, improve surface
finish and accuracy, and improve expected blade life.
1. A new blade must be properly "broken-in". Proper break-in will alleviate blade vibration, improve surface
finish and accuracy, and extend blade life. The most convenient way to do this is to cut the intended work-
piece, at the standard recommended blade speed for that material, but with the feed rate reduced to about 25%
of normal. Near the end of the first cut, increase the feed rate again, and once again when the blade
approaches the end of the second cut. Keep increasing feed rate in this fashion, so that normal feed rate is
reached after 100 to 120 sq. inches of cutting.
2. Generous coolant application is essential with almost all materials. A high quality and well mixed
coolant will dramatically extend blade life, and will increase cutting rate and surface finish. On those few
materials where coolant is undesirable, a slight coolant flow 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. Stock movement during cutting will strip
blade teeth. Noticeable stock vibration reduces cutting performance and blade life - consideration should be
given to reorientation of the stock, or additional clamping measures (e.g. wood between vise jaws and work-
piece).
4. The proper blade speed for the work-
piece material must be selected.
Use the following chart as a starting point.
- Blade speeds higher than recommended
will quickly dull the blade. Blue chips are
evidence of excessive blade speed.
- Lower than recommended speeds will
not prolong blade life, and will require reduced
feed rate - but reduced speeds may be helpful
in reducing vibration, and will increase blade
life in that case.
5. The proper feed rate must be applied.
Feed Rate is the speed which the head "free-
falls", and is set with the feed rate control
knob. The head will descend more slowly
when the blade encounters the work-piece but
the force of the blade on the work will not be
changed unless the setting is changed.
Verification of proper feed rate is provided by the appearance of the cut chips which ideally form nicely curled
"clock springs". (Note that cast irons, and interrupted cuts result in short, broken chips even at ideal feed rates).
- Excessive feed rate will result in short blade life and/or crooked cuts.

DETERMINE OPTIMUM BLADE PITCH
TEETH PER INCH (T.P.I.)
Selecting a blade with proper tooth pitch is important in order to
achieve optimal cutting rates and good blade life.
For cutting narrow or thin wall structural materials a fine, blade
with many teeth per inch (T.P.I.) is recommended. For wide
materials a blade with a coarse pitch should be used. See the
sketch below for the blade pitch changes fordiffering effective
material widths.
It is impractical to change the blade to the proper pitch every
time a different width of material is cut and it is not necessary, but
remember that the optimum blade will cut most efficiently. Too
fine a blade must be fed slower on wide material because the
small gullets between the teeth will get packed with chips before
they get across and out of the cut. Too coarse a blade must be fed
slower because it has fewer teeth cutting and there is a limit to the
depth of a cut taken by each tooth.
VISE OPERATION
The material clamping vise is a cam operated, double handle locking vise. The saw operator can push the vise
handle to close the jaw on the material and then lock it from either side of the saw. The handles have two
positions, forward toward the stock to unlock the vise, and away from the stock to lock. The following photos give a
visual guide as to the operation of the vise.

HEAD SWING and BREAK
An integral function of the S-23 is the ability to make
mitred cuts at angles between 90Oand 45O. The Head
swing of the S-23 is easily changed to set a different
cutting angle by first releasing the Angle Brake lever, and
then manually moving the Head to the cutting angle
desired. An angle scale with a pointer in clear view of the
saw operator allows for accurate setting of the cutting
angle. The Angle Brake lever is then locked in position by
forcing it into the down position. It should be noted that the
angle brake should be locked into position whenever
cutting with the saw. The photo illustrates the Angle Brake
in the locked position at 65 O. To set the saw to the 90O
position, the Head ( in the fully down position ) is moved
until the frame meets the 90Ostop bolt which is located in
the coolant tray at the drive end of the head.
BLADE SPEED ADJUSTMENT
Blade speed can be adjusted infinitely between 75 to 350 SFM (Surface Feet/Minute) (23 to 106 m/min).
Adjustment should be made only when the blade is running. Clockwise rotation of the knob increases blade speed
while counter clockwise rotation decreases blade speed.
It is recommended to occasionally run the speed adjustor through it’s full range. This will help in maintaining the
pulley system. It is also recommended that if the same speed is used for long periods, then a minor adjustment
should be made,eg; 200 SFM should be run at 190 or 210 SFM for part of the time. This will help in reducing wear
grooves and keep the speed adjustment smooth.

COOLANT FLOW
The S-23 bandsaw is equipped with two needle valves
that independently control the coolant nozzles which are
capable of supplying a generous flow of coolant to the
blade.
The left (idler) guide arm nozzle supplies a flow of
coolant that should flood the blade as it moves through
the carbide pads into the material to be cut. The
adjustable valve on the left guide arm should be set to a
higher flow as a higher blade speed is used to provide
the flood of coolant necessary.
The right (drive) guide arm provides an adjustable
coolant flow through the needle valve and the flexible
hose nozzle that can be pointed directly where
necessary. This flexible hose should be used when
cutting solid bars, bundles, or wide structurals. Set the
flow of coolant directly into the opening in the material
where the blade is cutting.
NOTE: When cutting materials that do not need constant coolant, such as Cast Iron, some coolant flow is
required for blade lubrication to prevent blade scoring by the carbide pads as the blade moves through them.
GUIDE ARM POSITIONING
The S-23 guide arms are adjustable to accommodate
varying material widths. The guide arms should be adjusted as
close to the material width as possible while still allowing the
material to pass between them. This process of matching the
guide arm spacing to the material size is important to optimize
blade life.
To adjust the guide arm pacing the locking handles are
loosened by turning them counter clockwise. The carbide
locking lever is then moved in the counter clockwise direction
so that the carbides release the blade. The guide arms will
then slide on the main guide bar which supports them.
To tighten the guide arm, the handle is turned clockwise
until the handles are in the locked position (4 to 6 o'clock) as
illustrated in the photo. The carbide locking lever should be
moved to the upright tensioned position.
