Modifications:
 Any modifications to the machine including incorpora-
tion into an assembly, addition of integrated feeds or
other changes are the responsibility of the end user
and the end user must ensure ongoing compliance.
Additional Safety Actions to be Take by End
User
 Lock out Tag out procedures to be adopted during all
maintenance.
 Lock out Tag out procedures to be observed when
changing blade
Functional Testing
 Braked run down times test—tested monthly
(20 second brake run down )
 Upper Guard locking—tested monthly, prove there is
an inability to open upper guard without tools.
 Test lower guards for hang ups make sure upper plas-
tic section drop down to cover blade
 Test lower ring guard (inner) test to make sure it moves
freely, it is not bent, and does not hang up– must drop
freely to lower portion of blade
Instructions for Use:
 • Always observe the safety instructions and applicable
 regulations.
 • Ensure the material to be cut is firmly secured in
place.
 • Apply only a gentle pressure to the tool and do not
exert side pressure on the saw blade.
 • Avoid overloading.
 • Install the appropriate saw blade. Do not use exces-
sively worn blades. The maximum rotation speed of the
tool must not exceed that of the saw blade.
 • Do not attempt to cut excessively small pieces.
 • Allow the blade to cut freely. Do not force.
 • Allow the motor to reach full speed before cutting.
 • Make sure all locking knobs and clamp handles are
tight.
 • Never run the machine without the guards in place.
 • Never lift the machine by the table top.
Preventative Maintenance
Original Radial Arm Saws are designed to provide you
with precision cutting with a minimal amount of
maintenance. The frequency of the maintenance de-
pends on the amount of use and the desired cutting
quality.
Always disconnect and lockout power supply
before performing maintenance.
 After every 160 hours of use, the column should
be wiped down with a clean, dry rag.
 Wipe the tracks of the arm with a clean rag and
either denatured alcohol or paint thinner to remove
wood pitch buildup. Move the carriage back and
forth several times and clean it again. DO NOT
lubricate the arm tracks; doing so may cause ex-
cessive arm wear due to dust attracting to the arm
tracks.
 Keep the tracks clean and dry.
 Pull carriage from the arm and wipe bearings with
denatured alcohol or paint thinner.
 Periodically wipe or vacuum sawdust from all ex-
posed surfaces. Check for loose or broken parts
and replace if necessary with genuine Original
Saw Parts. Check the blade to see if it is sharp
and free of wobble.
 Adjustment and alignment of saw is necessary
only when cutting results in unacceptable accura-
cy.
 After many years of use your saw may need re-
placement parts. If any of the following wears out,
all others listed should be checked also.
Roller head bearings: Check for free, smooth
rota- tion. Do not attempt to lubricate.
Arm Tracks: If the saw is used primarily for
short cut-offs, the tracks may wear making it difficult
to adjust the roller head bearing for full length
arm travel. Arms can generally be re-machined—
contact Original Saw for pricing and shipping
n structions.
Motor bearings: Check for free, smooth rota-
tion. Do not attempt to lubricate.
Elevating mechanism: Remove, clean and
lubri cate with type EP grease. Check for wear
between nut and jack screw. Replace assem-
bly if loose.

SAW ASSEMBLY AND INSTALLATION
UNPACKING YOUR 3512 SERIES SAW
Your 3512 series saw system has been completely assembled, tested, and then partially disassembled.
The shipment of your saw contains the following items:
 The 3512 Series Saw, (4) frame legs, arbor wrenches, allen hex wrench kit, hardware to attach
legs.
Your machine will be banded down to a shipping skid with the legs removed and packaged under
the table top. To uncrate, simply remove the corners and the framing from the skid and cut the
bands that hold the saw to the skid. The unit can them be picked up with a forklift under the steel
frame and then the legs can be installed using the 3/8 bolts, lock washers, and heavy hex nuts.
Make sure to use the leg with the warning stickers on the left front. Install bolts finger tight and place
machine where it is to be set up. Then tighten legs. This will allow machine to level itself to
the floor.
Important
All cable lengths have been adjusted during manufacture to allow for proper movement of the arm and
rollerhead. However, you should check the cables to ensure full range of movement. If adjustment is
necessary, loosen the 2 cable clamps (1 inside of arm, 1 at right rear of arm) and adjust the cables so
rollerhead is free to travel the total length of the arm with the motor pivoted in the roller head so the
blade is on the right hand side. Also, check to ensure there is enough slack in the cables between the
rear of the arm and the starter enclosure so the arm can be swung to the right a full 900 while the arm is
elevated to its highest position.
FLOOR MOUNTING DIMENSIONS
Your saw may be mounted to the floor using 1/2”
diameter hardware appropriate for the floor surface
and located according to the diagram below. All
dimensions are center-to-center.
Electrical Hookup -
Recommend Copper Wire Sizes (A.W.G.)
To obtain maximum efficiency from your saw motor, the feeder
wire from the power source to the machine should comply
with the table below.
NOTE: This table is based on 60-100’ distances from power supply. Less than 60’ may use one even
size smaller (high number = smaller size); 100-160’ use one even size larger, over 160’ use two even
sizes larger.
Electrical Precautions
1. Be sure machine is properly grounded.
2. Do not attempt to operate saw on any voltage other than the one designated.
3. Use correct size time delay fuses to protect incoming current.
4. If it takes more than 3 seconds to reach maximum speed with a standard blade, turn the saw off. ( See trouble shooting on
page 28 of this manual).
5. Do not cause the motor to repeatedly approach a stall.
6. Do not attempt to start the saw for at least 15 minutes after thermal overload has tripped.
7. Disconnect and lockout the saw from the power source before opening a starter box, conduit box or whenever
removing a guard.
Connecting Electrical Current
The motor is properly connected to the magnetic switch at the factory for operation on the electrical voltage specified on the tag
attached to the guard stud. Make sure incoming voltage from your power supply conforms to the voltage specified on the tag.
Remove the magnetic switch cover and insert power supply cable through the dust proof fitting. Connect wires to L1, L2 and L3
for 3 phase; L1 and L2 for single phase (See next page left photo). Do not attach power to the transformer. Attach the ground
wire to the ground lug inside the switch enclosure. Wiring must conform to the National Electrical Code and any applicable local
codes.
Your saw may be mounted to the floor. Use
the diagram at right to assist you in placing
the saw and fastening it to the floor.

SAW ASSEMBLY AND INSTALLATION
Check Arbor Rotation (3 Phase Only)
Check arbor rotation with arbor nut and arbor collars removed. Open line disconnect to the saw to remove arbor nut and col-
lars, close the line disconnect and start saw. The rotation of the arbor must be clockwise as indicated on the arrow on the
nameplate. If the rotation is counterclockwise, the incoming wires are not properly connected to the switch box. To change the
direction reverse any two of the wires leading to the switch box from the power supply.
Changing Voltage on dual voltage motors and Resetting Thermal Protection
Dual voltage motors can be operated on either of the two voltages indicated on the motor
nameplate. The voltage setting from the factory can be found on the tag attached to the
guard stud. To change the voltage:
1. Change the motor lead connections as shown on the diagram on the inside cover of
the motor conduit box. This is also found on page 23 in this manual. Disconnect and
lockout the power supply before attempting voltage change.
2. Reconnect the transformer in the magnetic starter as shown in the diagram on the
inside of the starter box cover. This is also found on pages 23 of this manual.
3. Replace or adjust the thermal overload protectors (D) using dial (A), see below right)
with those rated at the desired amperage range. See page 23 of this manual. If the
overloads trip you will need to press reset button (C) to resume operation.
4. Contact your dealer or customer service via phone at 800-733-4063 or email at
[email protected] for correct information on thermal overload
protectors.

Mounting the Blade (Caution! Disconnect power source before mounting blade.)
1. Place the hex box wrench over the arbor nut and place the long allen wrench in the arbor shaft end hole. Place a wood
striking block under the allen wrench to avoid marring the tabletop. Push down on the hex wrench to loosen nut (left hand
threaded). (See figure 2)
2. Remove the nut and first arbor collar. Wipe the arbor collar faces and mounting area on the blade. Slide the blade on the
shaft with the directional arrow away from the motor and pointing clockwise.
3. Place the arbor collar, recessed sides against the blade, arbor nut and tighten securely. ( See figure 1)
Guard Mounting (note guard is installed when machine is shipped)
(Caution! Disconnect/lockout power source before mounting guard)
See parts listing and diagram on page 26
1. Remove the 1/4”x 20 Hex nut or wing nut from the right front lower guard mounting stud and remove the retainer washer.
2. Remove the right lower guard by sliding it backward and down.
3. Place the guard over the blade, tilting the guard to the right so the HDPE lower guard sections clears the end of the arbor.
4. Seat the die cast guard mount bracket in the groove on the front of the motor arbor end bell with the guard stud through the
hole in the guard. Secure with wing nut.
5. Reconnect the lower right guard and replace the parts removed.
6. Move the carriage forward across the fence to verify proper operation then pull to the limit of its travel.
Caution: Your saw is now ready to use. Before using it, study the control loca-
tions, cautions and operating instructions contained in the following pages.
FIGURE 1 FIGURE 2
Adjusting the Saw Guard
The guard can be pivoted about the motor by loosening the guard mounting wing nut. CAUTION—DO NOT ADJUST THE
GUARD OR ANTI-KICKBACK WHILE BLADE IS MOVING. KEEP ALL ADJUSTING MECHANISMS TIGHT.

16
General Safety Precautions
1. Be sure the blade rotates clockwise when facing the saw from the left side. Blade must rotate to the front of the saw.
2. Be sure all clamp handles are tight before turning on motor.
3. Keep the blade sharp and properly set.
4. Hold or clamp the material firmly against the guide strip when cutting.
5. Be sure the blade and arbor collars are clean and the recessed side of the collars are against blade.
6. Never oil or grease arm tracks or motor.
7. Do not start machine without proper tool guard.
8. Do not remove the anti-kickback device (if equipped) from the blade guard. Adjust it to clear the work.
9. Keep motor air slots clean.
10. Return roller head to full rear after each operation.
General Cautions When Using the Lower Blade Guard:
1. Used properly, the lower blade guard is designed to provide protection from contact with the side of the blade. It is not
designed to prevent contact with the front or rear of the blade. When the lower guard contacts the fence or material
being cut it will rise up and expose the blade. Be careful to keep your hands out of the line of the cut.
2. Lower blade guards may become caught in prior kerfs in the fence or table. Alleviate this by replacing the guide fence
frequently. Always stop the saw before attempting to remove a guard that is stuck in a kerf.
3. Short cut-off pieces of wood may become caught between the lower guard and the blade. If this happens shut off the
saw and wait until blade stops to remove the piece.
4. The lower blade guard’s effectiveness is limited in bevel operations. It may have to be raised out of the way when set-
ting the bevel angle. Be sure the power is off/locked out and blade is completely stopped before making any adjust-
ment.
5. Catching the lower guard in saw kerfs when changing the saw setup can be avoided by elevating the saw until the bot-
tom of the guard clears the fence.
6. When ripping narrow strips the lower guard may have to be raised to rest on top of the guide fence. Be sure to use a
pusher stick to feed the work.
7. Do not use the lower guard with any accessory other than the correct size blade.
Using the Adjustable Arm Stop
The arm stop should be used whenever rollerhead travel needs to be limited, such as when repetitive cross cuts are being
made. Use of the arm stop will also prevent the blade from throwing small cut off pieces on the return stroke. Do not adjust
the arm stop unless the power is off and locked out and the blade stopped. The arm stop must be used on the
right side of the arm. Proper adjustment of the arm stop is completed as follows:
1. Pull the rollerhead forward far enough for the blade to sever the material and travel 1/4” past the material.
2. Lock the rollerhead to the arm with the riplock and place the arm stop so it is touching the rollerhead.
3. Loosen the riplock and return the rollerhead behind the fence.
Alternate Guide Strip Positions
Your saw was assembled with the guide strip in the
most frequently used position on the work table (see
figure 3). The guide strip may be moved to alternate
positions to accommodate varying uses. Moving the
guide strip behind the spacer board will allow for max-
imum cross cutting capabilities. Moving the guide
strip back to the rear board will provide for maximum
ripping capability.

!!! CAUTION !!!
BOTH UPPER AND LOWER GUARDS MUST REMAIN IN PLACE FOR SAFE CUTTING OPERA-
Rotating the Motor to Bevel Cutting
Position
Raise the arm to allow the saw blade sufficient clearance above
the table top. Release the bevel clamp handle (A) and pull the
bevel index pin. The motor can now be moved to a bevel posi-
tion as indicated on the bevel scale. Lock the motor by releas-
ing the bevel index pin (possible only at 0o, 45o and 90o) and
by locking the bevel clamp handle.
Operating Instructions
!!! CAUTION !!!
BOTH UPPER AND LOWER GUARDS MUST REMAIN IN PLACE FOR SAFE CUTTING OPERATION.
Moving the Arm Horizontally and Vertically
The elevating crank is used to raise or lower the arm to accommodate cutting operations (see below left). Do not adjust the
height of the saw while the motor is running. Change the position of the arm for miter cutting is done by pulling the arm
clamp handle (A) forward and lifting the miter latch handle (B). Observing the miter scale, swing the arm either right or left
to the desired angle. The arm can quickly be located at the 0oand 45omarks by using the indexing slots machined into the
column ring. When you have located the saw at the required position engage both the miter latch and the arm clamp.

Cross Cutting
Lock the arm in the 0oposition. Place the material
securely against the guide strip– keep hands well away
from the blade. Draw the saw blade across the materi-
al. After the cut has been completed return the blade
behind the guide strip. Observe this order of operation
for all cross cuts. Never push the saw blade into the
material. Pull the blade slowly and firmly across the
material from the rear of the arm using the operating
handle. The saw blade should cut into the table about
1/ 16” when cutting through the material. Raise the
anti-kickback to just clear the material being cut.
Adjust for varying wood thickness or warped material.
Operating Instructions
Bevel Cutting
Lock the arm in the cross cutting position.
Raise the motor by rotating the elevation
crank. Release the bevel clamp and the
bevel index pin and tilt the motor in the
yoke. The bevel angle is shown on the bevel
scale. Release the bevel index pin and lock
the bevel clamp. Lower the arm into cutting
position. Adjust the arm stop to assure
clearance between blade and base. Pull the
saw through as you would for cross cutting.
Compound Miter Cutting
The compound miter is merely a combination of
the bevel cut and the miter cut. Set up the ma-
chine for bevel cutting. Release the arm clamp
handle and the miter latch handle. Move the
arm into the required position and lock the miter
latch and arm clamp. Adjust arm stop to assure
clearance between blade and base. Pull the
blade through as you would for cross cutting.

Maintenance Adjustments and Alignments
Caution! Disconnect and lockout power supply before making any adjustments or
alignments.
Your saw has been completely assembled, aligned and tested at the factory...then partially disassembled for shipment. Han-
dling during shipment may cause some misalignment and the following information will enable you to correct any cutting
inaccuracy you discover. These adjustments may also be necessary after a period of use. (See preventive maintenance)
Important ...Since one adjustment may affect another it is important to run through the adjustments in the sequence as
follows.
Adjustment of Base to Column Fit
If excessive side motion exists at the end of the arm
while the arm clamp is engaged, adjustment to the
base or bronze gib (C) is generally necessary. To ad-
just:
1. Loosen all pinch bolts (A) and set screws (B). Pull
the arm clamp handle forward.
2. With the motor and yoke in the rearmost position
the elevation effort should be easy. Tighten the
bottom pinch bolt until there is an increase in the
elevation effort. Once elevation becomes snug
back off the bolt 1/4-1/2 turn. Repeat this for the
other two pinch bolts.
3. Tighten the gib set screws (B) hard, then back
them off. Run them back up against the gib light-
ly, then snug up the locknut.
Adjustment of the Arm Clamp
The arm clamp holds the arm tightly on the column
in the desired position for cutting. The arm clamp
handle should be upright when tightened. If it goes
beyond center adjust as follows:
1. Place motor carriage in the rearmost position.
2. Loosen the arm clamp set screw (A).
3. Move arm clamp handle to upright position and
tighten the arm clamp handle bolt (B). Note
this is a left hand threaded bolt.
4. Tighten the set screw.
Adjustment of the Rollerhead to Arm
Accurate work cannot be done if the roller bearings in the motor carriage are not in proper adjustment. When play develops
between the rollerhead and the arm the following adjustment is required:
1. Bring the rollerhead to the front of the arm and lock in place using the adjustable stop. Move saw to in-rip position.
2. Loosen the sockethead screws holding the arm end cap and rotate the end cap upward to expose bearings.
3. Clean the tracks thoroughly. Wipe them clean with a solvent, do not use kerosene. Use extreme caution as most sol-
vents are toxic and/or flammable. Do not grease or oil the tracks.
4. Loosen the locking set screws (A) two full turns to release the eccentric shafts. (Both are located on the right hand side)
5. Loosen the hex jam nuts (B) on both bearing pins.

Adjustment of the Rollerhead to Arm (cont’d)
5. Insert socket wrench into bottom of bearing shaft (C) and
turn until the bearing touches the arm track on both top
and bottom radii. Repeat for both shafts. Bearings should
be tightened only so that they roll and do not slide.
6. Replace the end cap and return saw to normal position.
Note-Too much pressure on the roller bearings will
cause excessive and unnecessary wear in the
parts and make the carriage work harder. Seven
to ten pounds average pull on the carriage is a
desirable preload.
Adjustment of Table Top Parallel to Arm
The arm tracks must be parallel to the tabletop at all
points. This assures uniform depth of cut, especially
when dado cutting. Remove the blade and insert an
arbor wrench or allen wrench between the saw arbor
collars. Lower the wrench until it touches the tabletop.
If the top is not level:
1. Locate the highest point by swinging the arm from
side to side and moving the carriage back and forth
on the arm.
2. Loosen the lock nuts beneath the table frame.
3. Raise the jack screws so as to bring the low parts of
the tabletop level with the high spots.
4. Tighten the lock nuts beneath the table frame.
How to check the Guide Strip For Accuracy
For accurate work the guide strip must be straight. If the machine has been exposed to the weather or used for a period of
time the wood parts may become warped or worn so that the guide strip is no longer straight. It should be made straight by
planing and sanding or replacing. Check it with a straight edge or square before proceeding and make any adjustments nec-
essary.
Caution! Disconnect and lockout power supply before making any adjustments or alignments.
