DAMAGE CLAIM PROCEDURES
VISIBLE DAMAGE AT THE TIME OF DELIVERY:
1. Note damage on carrier’s delivery receipt. Accept the shipment. It can be returned later if repairs
2. Request a “damage inspection” from the delivery carrier:
a. The carrier will send his own people or contract an independent agency to make the
inspection.
b. The inspector will request a signature on the report and leave a copy.
c. The carrier “damage inspection” report is not nal. If additional damage is found when
repairs are started, contact the carrier for another inspection; or at least give them the details of the damage.
3. Do not move the equipment from the receiving area and keep all shipping materials until carrier “damage inspection” report is complete.
4. If possible, take photographs of the damage and keep them for your les. Photos could possibly
prove a claim at a later time.

OSHA NOTICE!!
OSHA Regulation No. 1910.212 (5B).
Machinesdesignedforaxedlocationshall
be securely anchored to prevent walking or moving.
1. The machine and other parts and supplies were fastened to a wooden skid before shipment.
DO NOT remove the red metal bracket holding
the saw head to the vise base until the machine has been lifted and positioned at its permanent location.
2. Remove all protective covers, strapping, crating, etc. Then: (a) Remove the bolts or screws attaching the machine to the shipping skid.
3. Inspect the machine for broken or damaged parts. Refer to this manual's inside front cover for damage claim procedures.
CLEANING
1. If necessary, use solvent to remove the rust­preventative coating applied to the machine's exposed bare metal surfaces before shipping.
LIFTING
Never lift the machine by its sawing head.
MACHINE INSTALLATION
1. There are two (2) parts to the machine: the machine base and the indexer. The machine base is installed
rst and leveled before the indexer.
2. Before placing the machine down, install one (1) M20 leveling screw and nut into each base foot pad. Then: (a) Adjust the six (6) leveling screws to extend an equal distance through the mounting pad - approximately one-half inch (12.7 mm); (b) Tighten the jam nuts; (c) Just before lowering to the
oor, place a foot casting under each leveling screw
Now lower the machine in the desired location.
3. Remove the bracket holding the saw head to the base. Save this bracket for use in case machine
relocation becomes necessary at a future date.
4. Place a machinist's level on the vise bed. Then
adjust the leveling screws until the vise base wear plates are level in both directions and weight of
the machine is resting evenly on all mounting pads.

their status. These modules are for diagnostics and service only and needs NO interaction from the operator.
5. Exit. Press this key to return to the previous screen.
SAW BAND PREPARATION
Recommended Saw Band
1. The machine is shipped with a saw band installed. The saw band recommended for use with this
machine is 271 inches (6883.4 mm) long, 1-1/2
inch (38.1 mm), and has a .050 (1.27 mm) gage thickness.
Saw Guide Detail.
2. Follow these adjustment procedures: (a) Turn the adjustment screw clockwise until the xed and the movable inserts are tight against the saw band (do not tighten further); (b) Turn the adjustment screw back counterclockwise a 1/4 turn.
Band Tension
1. Band tension is factory set and will not need adjusting for some time. Tension is applied by a selector switch which is located above the drive bandwheel door.
2. A new saw band will stretch as it is being used. For this reason, it is advisable that the operator checks the band tension frequently.

SAW BAND PREPARATION (Continued....)
SAW GUIDE ARM ADJUSTMENT
1. Remove the old or broken saw band as described in
the previous section. Clean metal chips and other
foreign materials and debris from around the saw guides and both bandwheels.
2. Form the saw band into one large loop. Then: (a) Slip the saw band under the saw guide arms and into approximate position for placement; (b) With the saw band's teeth facing away from you, slip the looped saw band around the drive and idler bandwheels.
3. Turn the Band Tension selector switch to "ON" and then to "HOLD" to have just enough tension to keep the saw band in place and that adjustments can be made.
Band Twist Tool.
4. Using the band twist tool, twist the saw band 90° so that its teeth between the saw guide arms point down and to the right. Then: (a) Insert the saw band into the saw guide inserts and pull up against the back-up bearing; (b) Check the saw band's position around the bandwheels (its back edge must rest against each bandwheel ange); (c) Remove the protective cap from the saw band if necessary.
5. After all corrective adjustments have been made, turn the Band Tension selector switch to "ON".
6. Turn the saw guide insert adjustment screws clockwise until tight (do not over tighten). Then turn each adjustment screw back counterclockwise
a 1/4 turn.
7. Reposition the band brush and tighten the locking handle. Then (a) Unlatch the left saw band guard and put back in place; (b) Rotate the right saw band guard down and tighten the thumb screw; (c) Close both bandwheel doors and latch. Make sure both
door interlocks are engaged. Press the "EXIT" key
to return to the previous screen.
8. Press the Band/Cycle Start key. Run the machine briey and then press the Band/Cycle Stop key.
9. Open the bandwheel doors and check for saw band tracking. Make any corrections and close the bandwheel doors.
1. The left saw guide arm is adjusted by using
the "GUIDE ARM OUT/IN" keys on the SETUP Screen.
3. The best cutting results are generally obtained when the saw guide arm are positioned as close as possible to the stock.
When the saw head has been swiveled, make
sure the saw guide arm will clear the front vise jaw when lowering the saw head.
FEED FORCE ADJUSTMENTS
1. Feed force is the pressure exerted by the workpiece against the saw band's cutting edge. It is controlled hydraulically and regulated with the Feed Force valve. Turn the valve clockwise to "decrease" pressure, counterclockwise to "increase" it.
2. The following are important factors to consider when setting or adjusting the Feed Force valve:
Turn the Feed Force valve to a low setting if the correct feed force is not known. The operator can then increase or decrease pressure during operation to obtain the best cutting rate consistent with desired
blade life and stock cut nish. Always be sure to take a good chip.
Never start a cut with the maximum Feed Force valve setting. Blade damage may occur.
Certain work-hardening materials will require a
moderately heavy initial Feed Force valve setting to assure immediate penetration of blade teeth. Light feeds on these materials may cause the blade to slide over the stock resulting in saw band damage.
Generally, top performance from a sharp saw band results from relatively low Feed Force valve settings. It will be necessary to increase the setting as the saw band becomes duller. This will help keep the cutting rate constant throughout the life of the saw band.
WORK HEIGHT ADJUSTMENT
1. The work height mechanism works in conjunction with the head up proximity switch (1 PRS) to
assure that the saw head has raised sufciently
above the stock so manual stock positioning can be accomplished safely.
17
Page 22
WORK HEIGHT ADJUSTMENT (Continued....)
Work Height Adjustment.
2. To adjust, lower the saw head all the way. Then: (a) Loosen the lock knob; (b) Rotate the adjustment
ag to the desired work height indicated with the
pointer; (c) Tighten the lock knob.
3. There is a convenient metric equivalent chart for converting the work height to millimeters.
FLOOD COOLANT SYSTEM
Coolant Selection
1. Excessive heat build-up is the main cause of blade
tooth failure during band machining. Coolant
has both lubricating and cooling properties. Its application does the following: (a) Helps reduce the heat generated during sawing; (b) Helps prolong blade life; (c) Generally promotes more efcient cutting rates.
2. When making a coolant choice, the operator will want to consider the following points: (a) The type of material being cut; (b) The material's machinability rating; (c) Band speed and feed rate to be used;
(d) Saw band type to be used and its expected life; (e) The overall sawing operation.
3. Using more than one (1) coolant variety may provide maximum sawing results and economy.
Literature describing different coolant types
and their application is available from a DoALL sales representative.
Coolant Application
SAW HEAD POSITIONING FOR ANGLE CUTS
1. To position the saw head for angle cutting from 0° to 60°, press the "HEAD ANGLE" key. Then: (a)
Press the "ENTER HEAD ANGLE" key and the
keypad will appear; (b) Enter the desired saw head
angle and then press "OK"; (c) Press "ROTATE
HEAD TO ENTERED ANGLE" to move the saw head to the entered angle.
2. The operator may use the "JOG +/-" keys to move the saw head to the desired angle. Press and hold
the appropriate "JOG" key and release when the desired angle has been reached.
3. See also the "HEAD ANGLE SCREEN" heading
previously described in this section of the manual.
The width capacities of the machine are
reduced when angle cutting.
1. Coolant is supplied by means of a reservoir and
pump to the cutting area through the saw guide inserts on the saw guide arm. A valve on each saw
guide arm regulates the ow to the saw guides.
Turn the valve counterclockwise until coolant completely covers both sides of the saw band.
2. Used coolant ows back to the reservoir by means
of a trough in the saw base. The reservoir has a
ltering screen surrounding the lter element to
keep out metal particles and other impurities.
Coolant Pump and Reservoir.
18
Page 23
FLOOD COOLANT SYSTEM (Continued....)
3. Coolant reservoir capacity is 25 gallons (94.6 liters). The pump will not operate correctly unless the lter
element is completely submerged in coolant.
Flushing Hose
1. Part of the Flood Coolant System, the ushing hose
is attached to the coolant pump and delivers cutting
uid through a hand nozzle. It is used primarily for
machine cleaning purposes.
Band Brush.
DRY CUTTING
1. The operator may nd it desirable to cut some
materials (such as cast iron, aluminum, magnesium, etc.) without coolant. When dry cutting these materials, follow the same operating procedures used when cutting with coolant. However, dry
cutting will reduce saw band life.
HYDRAULIC SYSTEM
1. The hydraulic and band drive systems operate independently. This allows the operator to perform the following tasks while the band drive motor is not running: (a) Change saw bands; (b) Raise or lower the sawing head; (c) Swivel the sawing head;
(d) Clamp or unclamp the vises; (e) Position stock
manually.
2. The machine's hydraulic reservoir has a 15 gallon (56.7 liter) capacity. Refer to the Lubrication section
of this manual for recommended iuds.
BAND BRUSH AND CHIP REMOVAL
Band Brush
1. A hydraulic motor driven band brush is located inside the drive bandwheel door. During machine operation, the brush bristles should be positioned so that the tips clean chips from the blade teeth gullets, but do not contact the bottom of the gullets.
DO NOT allow metal chips to accumulate on the brush.
2. The brush must be properly adjusted to clean blade tooth gullets if satisfactory sawing performance is to be obtained. As bristles wear down, adjust brush position by: (a) Loosening the bolts holding the bracket to the saw head; (b) Move the brush to the correct cleaning position; (c) Retightening the bracket bolts.
NEVER adjust the band brush while the saw
band is running.
Chip Removal
1. During operation, metal chips and used coolant
drop directly into a sloped trough, or ow into it from
the machine's run-off surfaces. Metal fragments removed from the band brush also drop onto the
saw base. Coolant then ows down the trough and through a ltering screen before returning to the reservoir. The ushing hose helps collect the
chips into the trough.
2. The chip trough collects the metal chips and can be raked to the opening at the machine's left side where chips can be emptied into a customer-supplied container.
Flushing Hose
1. Metal chips and other debris may accumulate over time around such machine areas as: saw guides, both bandwheels, vises, slides, band brush, head lift cylinder, feed and discharge areas, etc.
2. The operator should check often for metal chip collections which can adversely affect machine performance. They should be removed with either the combination shovel-rake or the Flushing Hose as soon as possible.
It is recommended that the operator remove
chips at least twice per each eight (8) hour shift, and more often with heavier use.
Be sure the saw ba n d ha v e STO P P E D
completely before cleaning the machine.

Page 29
HYDRAULIC SYSTEM (Continued....)
System Pressure
1. Hydraulic system pressure is correctly set at the factory and should not require adjustment for
a considerable period of time. Correct system pressure is 700 ±25 psi (48.3 ±1.7 bar or 49.2 kg/ cm².).
2. Pressure is adjusted by turning the screw extending outward from the hydraulic reservoir. Consult
a DoALL service representative if assistance is needed.
Pump Repair & Replacement
2. Check the coolant often for signs of contamination
or breakdown. The reservoir and coolant system should be drained and cleaned thoroughly when the
cutting uid becomes undesirable for further use.
If another type of coolant is to be used, the entire
coolant system must be ushed (use DoALL’s Kleen
Flush).
3. To thoroughly clean the reservoir section below the conveyor trough, removal of the trough will be necessary.
MACHINE CLEANING
1. Keep the machine and its parts as clean as possible to prevent excessive wear and damage.
1. DO NOT attempt to repair the hydraulic pump. Return it to the factory for repair or replacement. Be sure to specify the correct pump model and serial numbers when returning the unit.
2. Following a new pump installation: (a) Jog the Hydraulic Start and Hydraulic Stop keys several times; on for two (2) seconds, off for three (3) seconds until the pump is primed; (b) Check for proper pump rotation while jogging; (c) Review wiring connections if the pump rotates in the wrong direction.
After the pump has been primed, run it
for several minutes while operating the machine’s controls to purge entrapped air from the pump and system. Check for oil leaks while the system is being operated.
Seals & Cups
1. Seals and cups used in DoALL hydraulic systems are compatible ONLY with hydraulic oils having an aniline point between 215° and 230° F. (102° and
111° C.).
2. Use the Flushing Hose as soon as possible to remove metal chips and other waste materials which may collect around the saw guides, bandwheels, vises, slides, sensing arm, etc. The hose has a hand­operated valve and attaches to the coolant pump.
The DoALL Company recommends using the Flushing Hose to remove chips at least twice per each eight (8) hour shift, and more often with heavier use.
3. Use the supplied chip rake to remove accumulated metal chips or other waste materials from machine areas. Be sure the band drive motor is stopped
before opening machine doors or covers.
Chip Rake.
2. If hydraulic oil having an aniline point not falling within the above range is used, the seals may either swell or shrink and harden. This causes machine malfunction and leakage.

BAND BRUSH
Vise Bed Wear Plates
1. The band chip brush will wear and lose steel bristles
over time. Check often to be sure the bristles are
removing metal chips from the blade tooth gullets, but are not touching the bottom of the gullets.
2. Move the brush closer to the blade as normal wear occurs. Replace the brushes when necessary.
BAND TENSION MEASUREMENT
1. Band tension is factory set.
Band tension measurement can be made with the machine’s hydraulics running and by using the Band Tension selector and a DoALL Tensigage.
2. Tension may be checked "reading up" or "reading down". To "read up": (a) Fix the Tensigage to a slack saw band; (b) Apply tension. To "read down": (a) Fix the Tensigage to a tensioned saw band; (b) Relax tension.
3. A DoALL Tensigage reading of 28,500 to 30,000 psi
(1965 to 2069 bar or 2004 to 2115 kg/cm²) indicates
correct saw band tension.
1. Each of the two (2) front vise bed wear plates has twelve (12) mounting screws which must be removed. Replacement requires: (a) Removing the mounting screws from large outboard wear plate rst; (b) Removing the mounting screws from the two (2) wear plates and then slide them out from under the vise jaw.
2. Replace the wear plates in reverse order and install the hardware.
BAND DRIVE GEARBOX
1. Band drive gearbox replacement, repair, adjustment or alignment should be performed only by a DoALL service representative.
Using a Tensigage to Measure Band Tension.
WEAR PLATE REPLACEMENT
1. The removable vise jaw and vise bed wear plates must be replaced before excessive wear causes the mounting screw heads to become damaged
and makes removal difcult.
Vise Jaw Plates
1. The machine has six (6) vise jaw wear plates: two (2) on the front vise movable jaw and four (4) on the index vise jaws. All wear plates are mounted with low-head screws. Be sure the vise jaws are
separated and the machine turned off before trying to replace the wear plates.
Drive Gear Box.
2. To change the oil, drain the oil through the drain plug as shown. Fill with three (3) gallons (11.4 liter) of oil until the oil level is to the top of the elbow.
Fill very slowly so the oil can seep through
the bearings, gears, etc. This may take a few minutes.
BANDWHEELS
Bandwheel Flange and Tread.
26
Page 31
BANDWHEELS (Continued....)
1. Occasionally check each bandwheel’s back-up
ange and wheel tread for wear. Saw bands will
not track properly if the taper is worn from the wheel tread.
2. Replace the entire bandwheel if the rim becomes badly worn.
3. Ideally, the saw band should be tracking on both wheels so that the back edge will just lightly contact
the wheel anges, or is not more than 0.005 inch (0.127 mm) away from the anges.
CLEANING CHIP TROUGH OR CHIP AUGER
1. To clean the chip trough or optional chip auger, turn the machine off. Then: (a) Remove the cover and pull the trough or auger (disconnect the auger
hydraulic hoses rst) from its cradled position in the base/coolant reservoir; (c) Clean the removed trough and the trough in the base as well; (d) Clean the reservoir oor; (e) Replace the trough or auger
and reinstall the cover.
2. The machine’s coolant reservoir has a 25 gallon (94.6 liter) capacity.
3. Check the coolant often for signs of contamination
or breakdown. The reservoir and coolant system should be drained and cleaned thoroughly when the
cutting uid becomes undesirable for further use.
If another type of coolant is to be used, the entire
coolant system must be ushed (use DoALL’s Kleen
Flush).
Counterbalance Spring.
Be sure the saw head falls only enough to
cut completely through the work. TOO MUCH head fall could result in cutting the vise bed wear plates too deeply or completely off. TOO LITTLE head fall will result in an incomplete cut through the workpiece.
ELECTRIC MOTORS
1. Follow the manufacturer's maintenance instructions for each electric motor. These instructions are located in the pocket inside the main electrical enclosure.
4. To thoroughly clean the reservoir section below the chip trough, removal of the trough will be necessary.
COUNTERBALANCE SPRING
1. After a period of time, the saw head may not cut through the stock or cuts too far into the vise bed wear plates. To adjust, follow these procedures:
There is no need to remove the counterbalance spring from the machine. (a) Loosen the threaded collar from the lower hex nut; (b) Adjust the lower hex nut up or down until the saw band teeth are approximately 0.06 inch (1.52 mm) below the work surface; (c) Turn the threaded collar down tightly on top of the hex nut and secure it.

ACCESSORIES
ROLLER STOCK CONVEYORS
1. Your machine may be equipped with one of the following roller stock conveyors for moving long stock into cutting position (or as an unloading adjunct). The following conveyors are available:
Light duty stock conveyor ve (5) feet (1525.0 mm)
long by 33 inches (838.2 mm) wide with a weight capacity of 750 pounds (340.2 kg) per roller.
Light duty stock conveyor ten (10) feet (3050.0 mm) long by 33 inches (838.2mm) wide with a weight capacity of 750 pounds (340.2 kg) per roller.
VERTICAL GUIDE ROLLERS
1. Vertical guide rollers are effectively used to help maintain correct positioning of long stock on the
indexer roller bed and/or a conveyor.
When the Nesting Fixture is supplied, the vertical guide roller is a standard component.
2. This can be installed at the end of the indexer or between conveyors (if more than one is supplied).
3. One (1) vertical roller is adjustable along the guide
rail and clamped to laterally conne stock when
indexing.
Roller Stock Conveyor.
Heavy duty stock conveyor ve (5) feet (1525.0 mm)
long by 33 inches (838.2mm) wide with a weight capacity of 2000 pounds (907.2 kg) per roller.
Heavy duty stock conveyor ten (10) feet (3050.0 mm) long by 33 inches (838.2mm) wide with a weight capacity of 2000 pounds (907.2 kg) per roller.
2. To install a roller stock conveyor: (a) Position the assembled conveyor(s) behind or in front of the machine base; (b) Adjust the conveyor to the machine with the leveling screws on the conveyor legs. The top of the front conveyor roller should be inline to 0.010-inch (0.25 mm) above the vise bed wear plate.
3. The remaining rollers must be parallel to, and in the same plane with the vise beds to within 0.010-inch (0.25 mm) per 24 inches (609.6 mm) of travel.
4. Depress the roller shafts for ease of installation or removal of rollers.
Vertical Guide Roller.
NESTING FIXTURE
1. This optional feature is designed for high-production, multiple sawing of stacked bars, rounds and tubing. This option has the same capacity as the standard capacity.
When the Nesting Fixture is supplied, the vertical guide roller is a part of this option.
2. Vertical nesting clamps are mounted to the machine’s front and index vises. The cylinders operate simultaneously with the regular vise clamping cylinders.
3. The hydraulically operated Nesting Fixture can also
be used with the Variable Vise Pressure option.
The conveyor DOES NOT attach to the machine
base.Anchortheconveyortotheoorafter

NESTING FIXTURE (Continued....)
Nesting Setup
1. When the operator presses the "NESTING MODE
ON", the key below changes to "NEST SETUP".
This also changes to "HOME FRONT" mode which uses vise overlap clamping and releasing to permit at least one vise is always clamping the material. This is the default setting and cannot be changed
in "NESTING MODE ON".
Nesting Fixture Adjustments.
Stacking Stock
1. Correct stock nesting is essential for proper clamping of the vises and nesting xture. It is important that
nesting vise clamping pressure be transmitted to every stacked piece. Sometimes this can be more easily accomplished by manually jogging the stack.
2. Proper stacking of round stock is important because
saw band breakage may occur if round nested pieces slip or spin during sawing.
3. Two (2) workable round stock stacking methods are shown in the next illustration (using the same number of rounds in each row usually provides the best sawing results, although the alternate method can be used if the material is not stacked too high).
Nesting Mode On and Nesting Setup Keys.
2. Pressing the "NEST SETUP" key brings the operator
to a screen which allows independent opertation of all vise movement. This allows the operator to "build a nest" of material and using these vise controls helps keep the nest from collapsing.
Round Stock Stacking Methods.
4. Pieces should be stacked as closely together
as possible. Metal chips lodged in open spaces between individual pieces will affect cutting accuracy.
Nest Setup Screen.
3. All the controls operate the same way. Press and
hold the desired vise control key. Release the key to stop vise movement.
4. Press the "EXIT" key to return to the previous
screen.
5. Adjust the vertical guide roller so the stock will be guided correctly toward the saw band.
33
Page 38
NESTING FIXTURE (Continued....)
6. Press the "FRONT VISE CLAMP" key and the "INDEX VISE CLAMP" key on the VIEW Screen.
2. Clamping pressure is set with the adjusting knobs
until the desired pressure is shown by the indicator gauge. Turn the knob clockwise to "increase" pressure; counterclockwise to "decrease" it.
7. The out of stock photo switch (1PCS) is located on the rear side of the indexing vise. When the light beam is unbroken, an out of stock condition exists.
Workstation Controls
1. On the SETUP Screen, make sure that the "NESTING MODE ON" key is active. This changes to the "HOME FRONT" mode which uses vise overlap clamping and releasing to permit at least one vise is always clamping the material. This is the default setting and cannot be changed in "NESTING
MODE ON".
For Best Nesting Cutting Results
1. Stack the same number of stock pieces in each row.
2. The stack should always be higher than it is wide.
3. Increase the nesting vise clamping pressure will increase the holding load per piece.
4. Apply as much coolant as possible while cutting.
5. Replace wear plates on the moveable vise jaw and
nesting xture’s vertical clamping jaw when they
become worn.
3. Turn the locking knob to hold the pressure setting in place.
Typical Variable Vise Pressure.
4. Variable vise pressure also can be used with the Nesting Fixture Option.
CHIP AUGER
1. During operation, metal chips and used coolant
drop directly into a sloped trough, or ow into it from
the machine's run-off surfaces. Metal fragments removed from the band brush also drop onto the
saw base. Coolant then ows down the trough and through a ltering screen before returning to the reservoir. The ushing hose helps collect the
chips into the trough.
6. Adjust the feed table’s vertical guide rollers to keep the stack from collapsing when the vises are unclamped.
7. Generally, reduced band speed and feed force are necessary when sawing stacked materials. This results in a lower cutting rate than when sawing solid stock.
8. In some instances, increased production and blade
life may be obtained by nesting fewer pieces than maximum vise capacity permits.
VARIABLE VISE PRESSURE
1. Two (2) pressure reducing valves, located behind
the xed and index vise directional control valves,
are used to adjust vise clamping force against materials which cannot tolerate full vise clamping pressure (examples are thin-walled tubing, pipe, light structurals, etc.).
Chip Auger.
2. The chip auger, which sets inside the coolant reservoir, operates simultaneously with the hydraulic pump motor. The auger screw rotates slowly at the bottom of the trough. Its movement carries metal chips to the opening at the machine's left side where chips empty into a customer-supplied container.
34
Page 39
CHIP AUGER (Continued....)
MATERIAL HANDLING EQUIPMENT
3. A valve located on the base near the chip auger exit allows the chip auger motor to be adjusted for faster or slower operation. Turn the valve stem
clockwise to "decrease" the chip auger speed; counterclockwise to "increase" it.
BAND MIST LUBRICATOR
1. See the instructions sent with the unit for information on operation and adjustments. They are located in the pocket inside the main electrical enclosure.
2. Plant air supply is connected to the air lter to the
right of the main electrical enclosure on the front
of the machine. Plant air supply should be 80 to 90 psi (5.5 to 6.2 bar or 5.6 to 6.3 kg/cm²) to operate
this option.
DONOTexceed90psi(6.2baror6.3kg/cm²)
air pressure.
WORKLIGHT
1. The worklight illuminates the cutting area and areas nearby and is controlled by an "ON - OFF" switch on the light.
1. Special material handling equipment can enhanced
the performance of your machine. Contact your
DoALL sales representative for information on any material handling application needs that could increase your productivity.
LASER LINE OPTION
To avoid eye damage, DO NOT stare into the
laser beam.
1. A laser devise is used to emit a line on the material to be cut. This line shows the approximate spot where the cut will take place.
2. The devise is controlled by a "ON" - "OFF" key on the SETUP Screen. Turn the laser "OFF" when not in use.
3. The laser is mounted on the saw guide arm and is adjustable to position the laser beam where desirable.
4. When the laser is turned on, a warm-up period of 3 to 5 seconds take place before a line appears. If
the line is difcult to see, darken the work area to
enhance the line.
5. Remove the protective shipping cap from the laser devise before operation and replace the cap when not in use.
