Installation and Set Up:
The CTD saw you have purchased is designed to cut wood, aluminum, plastic and steel, with of course the
proper blade and conditions. For the material you are cutting, please refer to the cutting instructions for each
material type. The CM60 uses a NEMA 182T Frame 3 H.P., or NEMA 184T Frame 5 H.P. 1725 RPM, 60 Hertz
TEFC Motor. CTD uses a speed-up so that the blade will run at approximately 12,000 SFPM on a 16” blade.
IMPORTANT: Before operating saw, please be sure to read the “SAFETY INSTRUCTIONS TO THE
OPERATOR” (see Page No. 7).
Note: The floor stand must be shimmed, leveled and bolted to the floor, or framed in to eliminate vibration.
Use holes provided in bottom of floor stand. All machines have been completely assembled at the factory,
then disassembled for shipment.
Assembly of Floor Stand, Support Tables and Measuring Gages:
Standard Machine—The standard model has been completely assembled. Fences are set at the centerline
of the blade (see Diagram “B” on Page No. 4). Adjust fences forward if necessary for your particular material.
The machine base must be level. The incoming material and outgoing material must lay flat on the machine
base (see Diagram “F” on Page No. 10).
Floor Stand— The Floor Stand must be shimmed and leveled, and if necessary bolted to the floor to eliminate
vibration.

Blade Installation (continued):
1. Remove Spindle Nut, P/N 9B1P44 and Outer Flange, P/N 90M03. If necessary, hold blade
in hand with rag or lower blade into a piece of wood, and loosen spindle nut by pushing down on a 15/16”
wrench.
2. Place blade on spindle with tips pointing down. Make sure Slinger (inner flange), P/N 60M03 and
blade surface are clean before putting blade on spindle. This is a critical surface and is ground within
.0005 flatness. Any debris or dust will wear this surface. Wipe both surfaces (blade and slinger) with
a clean rag.
A. The blade must ALWAYS rotate to the rear of the machine on the underside of the blade
(see Diagram “D”). Always check rotation before cutting a piece of material.
3. Replace Outer Flange, P/N 90M03 and nut as before and tighten (refer to Diagram “C”). Pull up with
15/16” wrench. Do not over-tighten. Snugging the blade is all that is necessary.
4. Replace Blade Guard Cover Assembly as before making sure Lower Blade Guard covers blade.
If blades were purchased from CTD, your machine has been set with your blades. If not, blade diameters may
vary. Check to see if the blade contacts the base or disc in the down position. If repositioning is necessary,
adjust down stop bolt located under Arm casting, P/N 6C001L or R.

Diagram “C”
Blade Installation:
Before setting blades on spindle, always shut off or disconnect air supply. With Motor OFF and Power
Disconnected, open blade guard door, exposing spindle assembly. Loosen wing nut on bottom of blade guard
strap and swing down. Slightly lower arm casting exposing spindle nut and flange.
These machines are general purpose in
their design, therefore the user should
attach any additional guarding to the
blade guard or table base if the cutting
application causes unsafe blade exposure.
This label is attached to the blade guard.
Never put hand or fingers near or
under the moving blade.Use a piece
of wood to remove short pieces from saw.

Electrical Installation:
The CTD CM60 uses 3 H.P. three phase 1725 RPM, 60 HZ TEFC (totally enclosed fan cooled) motors on a
NEMA 182T or 184T Frame. CTD uses a speed up drive so that the blade will run at approximately 2900 RPM.
Electrical installation should be performed by a qualified and certified electrician. It is highly recommended
that a lock-out or disconnect switch be located close to the machine between your main electrical panel and
the machine. This disconnect switch is used to shut off power to the machine and should be used whenever
the blades are changed, or at any time the machine is serviced and the blade is exposed. A Magnetic Starter
can and should be provided as an optional accessory. The starter protects the motor from overheating and
will not allow the motor to restart itself after power outages or undervoltage situations. (OSHA requires the
USER to install.)
Electrical Installation of Power to Starter by a Qualified Electrician:
All wiring from the motor to the starter has been completed and tested at the factory several times.
The voltage has been clearly tagged. DO NOT CONNECT ANY VOLTAGE THAT IS DIFFERENT THAN
THE TAGGED VOLTAGE, AS THIS MAY CAUSE SEVERE DAMAGE AND DANGER. Consult the factory
if any changes are needed.
Bring power lines to the top of the Magnetic Starter. Use dust proof connectors if available.
Single Phase Motors:
Connect leads to L1 (line 1) and L2 for single phase motors. (See Wiring Diagram for Single Phase Motors
below.) Green ground wire must be grounded to enclosure. If using type “SO” wire and plug, use a romex
connector through starter box and a grounded plug. Be sure to check rotation. The blade must rotate down
and to the rear on the underside of the blade (see Diagram “D” on Page No. 5).
Three Phase Motors:
Connect incoming power line leads to L1 (line 1), L2 and L3. (See Wiring Diagram for Three Phase Motors
below). Green ground wire must be grounded to enclosure. Be sure to check rotation as polarities may be
different. The blade must rotate down and to the rear on the underside of the blade (see Diagram “D” on
Page No. 5).
If a change in rotation is necessary, reverse any two of the incoming power wires. Example: If the blades
are running backwards and incoming wires are connected White L1, Black L2, Red L3, switch the Black
wire with the Red so that Black is connected to L3 and Red is connected to L2. This will change the motor
to rotate properly. Motor Load Amperes

Safety Instructions to the Operator:
1. KNOW YOUR CTD SAW. Read this instruction manual carefully. Learn the operation, application, and
limitations, as well as the specific potential hazards peculiar to this machine.
2. Avoid accidental starting. Make sure switch is OFF before plugging in power cord. A Magnetic Starter
is provided as an optional accessory to give the operator added protection. (OSHA required by user.)
3. Always use a plug equipped with a ground.
4. Always keep blade guard in place. Do not wire-up or chain-up, so that blade is exposed.
5. Be sure all unnecessary tools are removed from machine before turning on power.
6. Use safety goggles. Also use a face or dust mask if operation is dusty.
7. Support work. To maintain control of work at all times, it is necessary that material be level with
cutting surface.
8. Wear proper apparel. Do not wear loose clothing or jewelry. Do not wear a tie or gloves. These items
can get caught in the moving parts of the machine.
9. Do not over-reach. Keep your proper footing and balance at all time.
10. Maintain your machine in top condition. Use proper blades. Clean machine weekly for proper
maintenance.
11. Keep work area clean. Cluttered areas, benches and slippery floors invite accidents.
12. Avoid dangerous environments. Keep work area well illuminated.
13. Wear ear protection if exposed to long periods of very noisy shop operations.
14. Keep visitors away. All visitors should be kept a safe distance from work area.
15. Do not force the machine. The saw will do a better job and be safer to operate at the speed for which it
was designed. Forcing the saw can be very hazardous to the operator.
16. Use recommended accessories. Use of other accessories may be hazardous. Use this instruction manual
or consult CTD for the proper accessories available.
17. Do not drown the blade using a steady stream of coolant when cutting non-ferrous materials. Only spray
the work to cool it.
18. Be sure to use the proper blade for the particular material to be cut.
19. Disconnect power cord before adjusting, servicing, and before changing belts, or for installing
accessories.
20. Safety is a combination of operator COMMON SENSE and ALERTNESS at all times when the machine
is being used.
21. WARNING!!! DO NOT ALLOW FAMILIARITY (GAINED FROM FREQUENT USE OF YOUR
SAW) TO DULL YOUR AWARENESS!! ALWAYS REMEMBER THAT A CARELESS FRACTION OF
A SECOND IS SUFFICIENT TO INFLICT SEVERE INJURY!!
How to operate the CM60 Single Cut-Off Saw:
Before operating the machine, please read the “SAFETY INSTRUCTIONS TO THE OPERATOR” above.
Other important information and features need to be learned before operating the machine.
Rotation:
The blade must rotate to the rear of the machine on the underside of the blades (see Diagram “D” on Page
No. 5).
Blade Guard:
The blade and belt drive are enclosed. When the saw arm is lowered, the upper main blade guard remains fixed.
The blade continues through the work as the blade exits the lower part of the main blade guard. The lower strap
covering the slot remains in place. NEVER remove any blade guard part, exposing the blade. These machines
are general purpose in their design, therefore the user should attach additional guarding to the blade guard or
table base if his cutting applicationcauses unsafe blade exposure.

Diagram “H”
To Compound CM60 Saw Head:
1. Locate compound lock bolts on compound angle
plate. Using a 3/8” Allen Wrench (see Diagram “H”).
Loosen lock bolts.
2. Remove dowel pin from 90 position, located in pivot
bracket.
3. Manually move saw head to desired compound degree
setting by aligning pointer on degree quadrant.
There are positive pin stops at 90 vertical, 22-1/2 and
45 compound. Tighten lock bolts.
Instructions for Model CM60:
To Change Angle for Mitre:
1. To change miter angle on machine to the left, locate lock down bolts (Bolts A, B, & D) and loosen with a
9/16” box wrench.
2. Remove left horizontal material support by removing 3/8x16 socket cap screws. Manually rotate top base
to the left to desired degree setting, aligning angle mark with zero block. 45 and 90 stops are provided.
3. To change miter angle to the right, remove the horizontal material support on right side and the 90 degree
stop, using the proper allen wrench. Move bolt “A” from the tapped hole in the front of slot to rear tapped
hole in the same slot. Move bolt “B” from the tapped hole in the rear of slot to the tapped hole in the front
of slot. Manually rotate top base to the right to the desired degree setting, aligning angle mark with zero
block.
4. Tighten lock down bolts A, B, & D. If you desire to mitre beyond 45 to the right, then 45 stop must be
removed.
5. Fences will require adjustment front to back and side to side, so they will not be hit or cut by the blade.
Adjust as necessary.
-7-

Hand Operated Machines and Cutting Speed:
The blade is rotating at approximately 2900 RPM. When moving the blade through the material, the blade must
NEVER be allowed to dwell in the work. If fine finishes are required:
1. Use a sharp blade. Do Not Force the Cutting Action, causing the motor to stall.
2. Use a constant, even pressure when cutting through material.
Spring Return:
Each sawhead is equipped with a drawbar return spring. The function of the spring is to return the sawhead to the
rest position upon release of the handle. Do not adjust the spring pressure. If the spring breaks, Replace It
Immediately! Make sure spring is attached properly and Never use a hand operated machine without the
return spring in place.
Clamping and Work Slippage:
The work must never be allowed to move or vibrate as it is being cut. When the work is positioned against a stop,
it must be clamped either by hand holding or by pneumatic air clamps. Never allow unclamped work between
the blade and the stop, as the blade can grab the material and throw it—thereby causing damage to the blade,
the machine, and possibly harming the operator.
CTD offers both Horizontal and Vertical Clamps. The Horizontal Clamp pushes the material backwards against the
rear fence and is mounted in the keyways of the base. A Vertical Clamp holds the material down, against the table
base and is mounted through and on top of the fence bracket. Both clamps are offered as optional extras and are
highly recommended. If you purchased your machine with an Air Downfeed of the saw, the clamps are actuated
prior to activating saw head by depressing the Foot Valve. An Anti-Tie Down, Two Hand Control drives down the
sawhead. If clamps are purchased using a hand operated machine, then the clamps will move into position by pulling
the saw head down slightly. This releases the Automatic Valve (AV) to supply air to the clamps. Be careful not to
overtighten clamp cylinder bracket on the cylinder. This will cause irregular function of the cylinder.

Removing Material From the Blade:
If the machine is stalled while cutting, immediately shut saw off and disconnect power. NEVER attempt to
free the blade while the motor is still on. If a piece is bound on the blade, do not attempt to raise the blade
out of the material. Instead, tap the piece down on both sides of the blade with light pressure until the piece
has freed the blade.
Cutting the Material:
The material to be cut (both the incoming pieces and the cut pieces) must lay flat on the table base, or the
blade may bind the material. THIS CAN DAMAGE THE BLADE OR THROW THE CUT PIECE OUT
OF THE SAW, POSSIBLY HARMING THE OPERATOR (see Diagram “F”).
Diagram “G”Diagram “F”
Check your material for squareness using a 90 degree square. Material that is out of square will move when it is
cut, causing irregular mitres. (See “Irregular Mitres” on Page No. 16.) Additional tooling may be
required.Consult factory for more information.
Cutting Wood:
While wood is generally soft and simpler to cut than aluminum, it requires that the material be held in place
as the blade passes through the material. CTD suggests using a Carbide Blade with Alternate Top Bevel (AT)
for lighter wood sections and picture frame mouldings. This type of blade gives the finest of finishes. No
ONE blade will cut all materials perfectly. High laquers or mica mouldings require a special modified blade
for best results. Consult factory. Never use a wood blade to cut aluminum, as it will chip and fracture the
carbide tips of the blade.
Cutting Aluminum:
As with cutting any material, it is important that aluminum be clamped properly. Precision blades are
required for accurate cutting. CTD suggests and uses a Triple Chip Grind on all its non-ferrous Carbide
Blades. When cutting aluminum, or other non-ferrous materials, it is essential that the blades be lubricated
with a Sawblade Lubrication System or other blade lubricating system for the finest finish. See “Sawblade
Lubrication System” on Page No. 11 for more details.
Abrasive Cutting:
When abrasive cutting, cut at the fastest speed rate the motor will allow. Do not stall the motor. Blade will
glaze as a result of too slow a feed rate, or too hard a composition. Abrasive blades may break due to
movement of the work, twisting of the blades, or glazing of the cutting edge. Seldom do abrasive blades
break because of too fast a feed rate. The thinnest section of material should be presented to the blade.
For example, when cutting 1” x 2” stock, stand the piece up so the 1” edge is cut. Abrasive blades have
the tendency to wander when lengths of less than 1/2” are cut. The burr will normally be heaviest on the cut
piece. To eliminate this condition, the cut pieces should be clamped.

Sawblade Lubrication System:
The Sawblade Lubrication System is used when cutting aluminum or other non-ferrous materials. This system
normally uses a Water Soluble Oil mixture of 10 parts water to one part oil. The system operates by syphoning
the lubrication up the line to the spray nozzle. Any air leak will cause inconsistent fluid flow to the spray nozzle.
BE SURE your fluid is free from chips and other debris. A fluid container supplied with the machine contains
a One-Way Check Valve, Part No. B3P96 at the end of the clear fluid line. This check valve helps to hold the
lubrication in the line. However, after a couple of minutes the lubrication or oil will back-flow into the container.
Priming of the system may be necessary if the machine has been standing without use. The system may be shut
off by closing the toggle valve next to the vacuum pump. The fluid must be clean or the Vacuum Pump will clog.
CTD Bio Lubrication System:
The CTD biodegradable lubrication system operates by pulse spraying a minute amount of biodegradable
lubricant directly on to the saw teeth of the blade in time-measured increments. The majority of the lubricant
then dissipates with the heat of the cutting action. Chips coming off the blade are hot and dry, and are more
easily collected. (See specific instructions included with system.)
-10-
Combination Blades:
Any combination blade is basically an aluminum cutting blade. Significant blade life in between sharpenings
will be lost if a blade is used for cutting both aluminum and wood. The amount of production for either wood
or aluminum should be the determining factor in the assessment of the particular blade type to be used.
Please consult factory.
Sound Levels:
During normal running of the machine without cutting the typical sound range will be between 60-85 db.
Due to the wide variety of blades available, CTD cannot warrant that maximum allowable OSHA sound limits
can be met--particularly during the cutting cycle.
Cutting Plastic:
Plastic can be cut as easily as wood on the 200R Series Saws. However, because of its elastic properties,
the material can deflect as the blade passes through. Therefore, it is important to clamp the material as close
as possible to the blade and support it by use of fixtures. CTD offers Horizontal and Vertical clamps for
this application (see Page No. 9). Additional tooling may be required. CTD offers special modified blades for cutting
plastics.

Model CM60 Air/Pneumatic System:
The air pneumatic system on the CM60 is simple to use and understand, and easy to operate.
The main components of the air system are shown below in the Air Circuit Piping Diagram.
The system operates using a Two-Hand Anti-Tie Down Control for safety. Included with the Air Pneumatic
System are the main drive Cylinder and Valves, an Air Filter/Regulator/Lubricator, and one Vertical Pneumatic
Clamp. The Vertical Clamp is actuated prior to the activation of the saw head via a Foot Valve, P/N B3P53E,
(recommended for safety) which in turn energizes the Two-Hand Control. Note: Pressure must be maintained on
the Foot Valve until Two-Hand activation. The system will not allow unclamped material to be cut. The two hand
buttons must be depressed at the same time for the saw head to travel downwards. The system operates first by
depressing the Foot Valve, P/N B3P53E. This gives a signal to the Shuttle Valve, P/N B3P86, to allow air to pass
to the Two Hand Anti-Tie Down Control, P/N B3P110. By depressing both palm buttons simultaneously (at the
same time), a signal is given to the main 4-Way Control Valve, P/N B3P73 to change direction—allowing air to
pass to the main drive Cylinder, P/N B3P306. The Cylinder pushes the saw head down. The speed of descent is
controlled by the Speed Control Valve, P/N B3P60 located on the Cylinder. By releasing the Two-Hand palm
buttons, air is shut off to the main 4-Way Valve, it shifts direction and the main drive cylinder reverses.

Air Schematic
Air Circuit Piping Diagram

Air Supply:
The air supply must be turned off and all electrics disconnected before making adjustments on the power feed.
A working pressure of 75 PSI (pounds per square inch at 5.4 kg/cm) is required. An industrial-type compressor
of at least 3 CFM (cubic feet per minute) is recommended. An additional 3 CFM is required for Spray Mists.
A conveniently located valve should be supplied by the user to shut off the air line. Arms should be raised or
lowered by hand when setting up machine. The machine must use clean, filtered air. The speed of descent of
the saw head will vary if the air pressure varies. An Air Filter/Regulator/Lubricator is essential.
FR:
An Air Filter/Regulator is installed ahead of the air inlet to the machine. This system helps prevent foreign material from
entering the system. It also provides lubrication in the air supply which helps prevent valves and cylinders from sticking.
The FR is comprised of three different components.
1. The Air Filter Bowl is located on the left side and is provided with an automatic drain. This collects and
then releases foreign matter and condensation collected by the air filter.
2. The Pressure Regulator, which is located on top of the air filter, controls the amount of air pressure allowed
into the system. An operating pressure of 75 PSI @ 5.4 kg/cm2 is required. (This is set at the factory.)
Trouble Shooting the Pneumatic System for Downfeed of Saw Head:
If the Air Feed no longer has smooth action, check the Downstroke Control Valve, P/N B3P60. If there is no
Speed Control, replace with Part No. B3P60. If air is leaking from the bottom of the cylinder, replace Cylinder
with Part No. B3P306.
4-Way Valve:
The 4-Way Valve is the main control, five port valve located on the Air Feed Unit. If the saw is sticking in the
up or down position, the spool located in the valve probably is not shifting from side to side as necessary. This
condition is caused by unclean air passing through the system. The internal parts become gummed up, and the
air pressure can no longer shift the spool. A broken spring in the valve is another common cause. A 4-Way Valve
Repair Kit, P/N B3P76 is available for the valve.
Air Hold Down Clamps for the Material:
Both Horizontal or Vertical Air Clamps are available and can be purchased as an optional accessory. These
clamps pneumatically hold the material in place when the saw blades are cutting the material. If clamps are not
purchased, the operator MUST HAND HOLD THE MATERIAL. The clamps are controlled by a 3-Way Valve
mounted on the bottom of the Power Feed Unit. When the machine is in the rest position, the Upstroke Stud
contacts the 3-Way Valve, LV1. As soon as the Foot Valve is tripped, the clamps move into position. A manual
shut-off for the clamps is provided should you not want to use the clamps for a particular material.
Air Filter/Regulator

-13-
Foot Valve:
The Foot Valve, P/N B3P53E actuates the clamps into position. Once the Foot Valve is depressed, the Two
Hand Anti-Tie Down Control is energized and ready to activate. As soon as the Two-Hand Control buttons
are depressed, your foot can be removed from the Foot Valve. The clamp pressure will be maintained by
Limit Valve #1, P/N B3P50.
Speed Control of Blade Movement:
The downstroke speed of the blades is controlled by the Speed Control Valve, P/N 2B3P61 located in the
upper port of the main drive Cylinder, P/N 2B3P05. Adjust as required for best finish. The Upstroke Control
Valve, P/N B3P63 is located in port No. 5 of the main control Valve, P/N B3P73. Simply loosen nut on
machine screw (10-32 thread) and adjust in to slow down, or out to speed up.
Lubrication and Adjustments of Bearings:
NO LUBRICATION OR ADJUSTMENTS ARE REQUIRED. All CTD cut-off saws are assembled using
sealed, prelubricated ball bearings. The spindle and pivot assembly are constructed using preloaded belleville
springs. These springs eliminate the need for adjustments of bearings and also greatly increase the life of
the bearings.
Preventative Maintenance:
The 200R Series machines and CM325R are relatively easy machines to operate and maintain.
Following is a weekly check list of General Maintenance items. The best preventative maintenance advice
is to CLEAN THE MACHINE DAILY, especially around the pivot points on the machine.
General Maintenance Weekly Check List:
Always disconnect electrical power and air supply.
1. Keep machine clean—especially around pivot bracket and pivot bearings.
2. Blow off and clean around the cylinder
3. Check Air Filter Bowl for water and condensation build up.
4. Remove any scrap pieces and dust build up from inside floor stand (if purchased).
5. Check monthly;
A. For excessive belt wear
B. Make sure motor pulley set screws are tight.

If adjustments of the 45 mitre settings are necessary, you will need a precision draftsman’s triangle. Check
the 45 mitre by placing the triangle against the left fence and then sliding it over to contact the plate of the
Carbide Blade. Touch the triangle against the steel plate of the blade—not against the tips. If an adjustment is
necessary:
A. Loosen the lock nut on the adjusting screw (1/4-20 x 1 machine screw), that locks through the
45 stop bolt.
B. Adjust 1/4-20 screw until blade plate aligns perfectly with precision triangle. Now, tighten the screw and
nut. It is not necessary to move the 45 stop bolt.

Other Repairs:
See specific areas within the manual for additional information on repairs and maintenance.
Repair and Service:
Always use CTD factory authorized replacement parts and consult factory before making any repairs or
adjustments which may be unclear.
Fence Alignment and 45 Angle Adjustment of Blades for CM60:
All machines are preset at the factory for perfect 90 and 45 mitre cuts. If any adjustments are necessary;
1. Check alignment of fences—left to right as shown in Diagram “E” on Page No. 8. Use a two foot steel scale
or quality precision straight edge and lay flat on table base. Butt edge against fence bracket and long mea-
suring gage (if purchased). Touch the outside corner of the straight edge. If one side of the straight edge
pulls away from the fence, then the long fence gage is not in alignment with the left Fence, P/N 600M19.
2. Loosen 3/8-16 lock nut on Left Fence Bracket, P/N 200C05 and Fence Support Angle, P/N BF16. Clean
all surfaces of dirt or dust, and re-assemble as before (see Diagrams “A” & “B” on Page No. 4).
3. Re-align right fence to left fence with your straight edge. Once you are sure both fences are in alignment,
you now have a reference point to check your 45 mitre.
Irregular Mitres:
Irregular mitre cuts are almost always caused by out-of square material. Check your material with a 90
square and a straight edge. Material that has a high spot on the bottom will move, or roll forward as it is
being cut (even with pneumatic hold down clamps), thereby causing the blade to cut more on the inside
of the moulding than the outside. Another cause of irregular mitre cuts is too thin a blade plate thickness.
Blade plate thickness should be .095 to .110 on 12” blades. Blades will find the easiest avenue to cut
through material, and sometimes the blade plate will distort when cutting heavier sections. The drawing
is an example of a cut when blade plate is too thin for the material being cut.

CM60 Spindle Assembly and Bearing Installation Instructions:
Refer to spindle diagram on following page.
It is suggested that replacement spindle assemblies be purchased from CTD before disassembling. Old spindles can
be returned for bearing replacement and slinger refacing for a nominal fee. The CM60 spindle assembly provides for
a “slip-fit” between the outer races of the bearing and the housing or arm casting, and a “press-fit” between the inner
race and the spindle. Great care must be taken with ball bearings or the life of the bearings will be reduced. To
remove the spindle assembly;
1. Remove belt guard and loosen motor.
2. Remove Pulley Nut #9 by holding spindle pulley, or by holding the slinger with special clamp wrench
or strap wrench (consult factory). Loosen jam nut on spindle to the end of threads, but leave jam nut
on spindle.
3. Loosen set screws in pulley.
4. With jam nut on end of spindle thread (to protect threads), gently tap jam nut towards slinger side
using a lead or rubber mallet. The spindle assembly will begin to move out of the spindle housing.
Remove jam nut when assembly is almost out. Spindle Assembly, consisting of Spindle #1, Slinger #3,
and Bearing #4 will come out of housing. Pulley #7 will slide out of housing when spindle assembly is
removed. Bearing on jam nut side will slide out of housing.
5. Replace bearings or belts as necessary. If you purchased spindle assembly replacement, go to No. 10.
6. Bearing on blade side is press fit on spindle. If bearing on the blade side must be replaced, an arbor press
must be used to disassemble the bearing and the slinger from the spindle. Great care must be used in dis-
assembling, or the spindle will be scored or stripped by the slinger. Before pressing apart, scribe a line on
the face of the spindle and the slinger, so that they will be re-assembled in exactly the same position in
relation to each other.
7. Press off slinger and bearing from spindle.
8. Press new bearing onto spindle, making sure spindle is square to the bore.
9. Replace slinger, as above, making sure score lines match.
10. Bearing on jam nut side will slide out of housing. To re-install spindle in spindle housing, take Spindle
#1 (with Slinger #3 and Bearing #4) and slowly insert into housing.
11. Place Pulley #7 and Pulley Key #8 in center of housing with key in broached keyway. Belts must be
around pulley and through housing.
12. From jam nut side of housing, place Belleville Springs #9 into housing. Be careful they are inserted
correctly as shown in diagram.
13. Now, place bearing in housing and on spindle, being careful that bearing goes into housing square.
14. Replace pulley jam nut on spindle threads. Holding spindle pulley, or slinger with special clamp wrench
or strap wrench, slowly tighten jam nut. This will cause bearing to slowly push into housing. Tighten
thoroughly.
15. Tighten set screws in pulley.
16. The face of Slinger #3 must be checked to make sure the face (next to the blade) is running true. If it is
not running true, it should be refaced. To reface, use the side of a surface grinder wheel. Dress the face
of the slinger by rotating spindle in bearings slowly against the direction of the surface grinding wheel.
17. Place belts around motor pulley and tighten.
18 .Check alignment of motor and spindle pulley with a straight edge.
