Introduction

This manual includes the operating and maintenance instructions for the Wilton 12-inch Universal

Tilt Frame Vertical Cut-Off Band Saw, Models

VTF6-2 and VTF6-4. This manual also includes parts listings and illustrations of replaceable parts for the band saw.

Tilt-Frame Saw Features

Refer to Figure 1 for key features of the Model

VTF6 tilt-frame band saw. The tilt-frame band saw is designed to cut stock at various angles by tilting the saw frame to the desired angle. When tilted to the right, the saw can cut at angles up to 60 degrees.

When tilted to the left, the saw can cut at angles up to 45 degrees.

The machine consists of a base weldment onto which is installed all other machine components.

Major components include the base, the saw head, the rocker mechanism, the hydraulic system, the coolant system, the vise, and the machine operating controls and indicators.

The saw frame is mounted on a rocker mechanism which, in turn, is supported by pillow blocks. A disk attached to the forward pillow block has a cutting angle indicator.

The rocker mechanism, and therefore the tilt angle, is changed by an hydraulic cylinder mounted at the rear of the machine.

Angle Indicator

Vise Handwheel

Vise Jaws

The saw frame is supported by guide rails mounted on the rocker mechanism. When cutting a length of stock, the saw frame translates from the back to the front on the guide rails. The back to front movement is accomplished by an hydraulic cylinder.

The saw has a vise on the left side of the work table.

The vise is opened and closed using a hand wheel on the left front of the machine. The front

(moveable) jaw is supported by and moves using an

Acme screw. The vise has extra large, steel jaws that provide for clamping of various sizes and shapes of material.

Electrical Enclosure

The electrical enclosure is located at the right front of the cut-off saw. The enclosure contains the electrical components required to operate the saw.

(Refer to the Electrical Connection section.)

The operator's control panel is mounted to the top of the electrical enclosure. (Refer to the Operating

Controls section for further description.)

Saw Head

The saw head consists of a drive motor, a speed reduction gearbox, drive and driven blade wheels, saw blade guide bearings and a saw blade. Blade guards are provided to cover the exposed areas of the saw blade.

Access to the saw blade is gained through the blade wheel doors. The upper door is accessed from the left side of the machine. The lower door is accessed

from underneath the machine worktable. The covers are fitted with limit switches that serve as system safeties to prevent accidental motor start up during maintenance or blade replacement.

The saw blade is driven by the motor driven blade wheel and is supported by adjustable blade guides.

Blade tracking adjustment screws are provided in the tensioning mechanism in the saw frame, providing a means to keep the blade tracking evenly on the blade wheels.

A blade tension indicator is provided on the tension drum assembly. When correctly tensioned, a tab in the slot of the tension drum housing is aligned with a line scribed into the constant tension housing.

Three blade tracking adjustment screws and jam nuts are provided on the blade tensioning mechanism. The adjusting screws are used to change the tilt of the drive wheel as needed to ensure the blade tracks properly.

Blade Guides

The blade guide assemblies provide support for the saw blade to assure squareness and accuracy of the cut. Two blade guide assemblies are provided. The upper blade guide is located on an adjustable support in the saw frame. The lower blade guide assembly is mounted on a bracket just above the lower drive wheel.

When in use, the saw blade is twisted 90 degrees by the blade guides bearings and tungsten inserts. The blade is twisted to position the blade's cutting teeth toward the workpiece.

The blade guides consist of five blade-side bearings, a blade back-edge bearing, and two tungsten inserts. The side bearings assure that the saw blade is perpendicular to the cutting piece. The back-edge bearing assures that the blade is not deflected rearward when the blade begins to feed into the cutting piece. The adjustable carbide inserts provide lateral support for the blade.

A coolant hose fitting is provided on the blade guides to provide coolant flow directly onto the saw blade/workpiece interface.

Blade Tensioning Mechanism

A blade tensioning mechanism (refer to Figure 7) provides a means to set the tension of the saw blade. Blade tension is adjusted using a handle on the mechanism.

Coolant System

The saw has a coolant system to provide coolant flow to the workpiece. The coolant reservoir is located underneath the machine. The coolant pump/ motor is mounted on a plate on the top of the coolant reservoir.

Hydraulic System

The hydraulic system (refer to the Hydraulic

System Components illustration in the Replace-

ment Parts section) provides the hydraulic pressure required to operate the hydraulic cylinders that, 1) tilt the frame, 2) clamp and hold the rocker mechanism in position, 3) move the saw frame forward and rearward, and 4) control the feed rate.

The hydraulic pump and valves are mounted on the top of the hydraulic reservoir. The hydraulic reservoir is located under a cover at the rear of the machine.

The fluid level can be seen through an opening at the left rear of the machine (see Figure 5). The valve manifold is fitted with a hydraulic system filter.

A filler cap on the top of the tank is used to fill or replenish the reservoir with hydraulic fluid.

Setup and Operation

Before operating the machine, setup the machine and perform post-installation checks as defined in the following paragraphs.

Machine Setup

The saw has been adjusted at the factory. A number of test pieces have been cut using the saw to verify the accuracy of cutting. Therefore, the only setup operations required before releasing the saw for service are placing and securing the saw, and establishing the electrical connections to the motor.

(Refer to the Electrical Connection section for wiring requirements.)

Use a fork lift to move the machine to the installation site (see Figure 2). Place the saw where it makes the most sense for the operations you will probably be doing. If you are going to be doing cutoff work on very long stock, allow plenty of room for the length of the stock; provide infeed and outfeed

.

supports as required.

Remove the saw from the shipping skid and discard any hold-down devices that were used to secure the saw to the skid. Level the machine and anchor it to the floor using the holes in the feet of the machine base.

Installation

When installing the machine, make the following checks and follow the instructions provided:

1. Check machine for any shipping damage before starting assembly.

2. Setup the machine on a flat, firm surface. No special foundation is required. However, verify that the thickness of the floor is sufficient to support the weight of the machine.

3. Make sure the machine frame is not distorted when fastened to the floor.

4. It is suggested that the floor surface be treated to prevent coolant or hydraulic oil from being absorbed.

5. Provide sufficient clearance between adjacent walls and machines to allow handling of the length of stock expected to be cut.

6. Level the machine worktable using a precision level.

7. The operating environment for the machine should have an ambient temperature between

32° and 95° Fahrenheit (0° and 35° Celsius).

8. The handle of the vise handwheel is installed facing inward for transport. Make sure the handle is placed in the correct position before starting the machine.

9. Remove all shipping materials used for protection of the machine during shipping.

10. Mount all loose accessories to the machine before startup.

11. Insert coolant reservoir under the bottom of the machine. Mount coolant pump and pump cover.

12. Check direction of saw blade. The teeth should be positioned so they teeth are facing downward as it passes through the blade guides.

13. After connecting electrical power, verify that hydraulic pump runs in the correct direction

(observe direction of arrow on motor). This is absolutely necessary for the pump to build up hydraulic pressure.

Electrical Connection

Observe the following when connecting to facility power. (See Wiring Diagrams section.)

WARNING: WILTON RECOMMENDS THAT ANY

HARD WIRING OF THE SAW TO FACILITY

POWER OR ANY CHANGE IN VOLTAGE SUP-

PLIED TO THE MOTOR BE PERFORMED BY A

LICENSED ELECTRICIAN.

1. Make sure the saw is disconnected from facility power. Make sure fuses have been removed or make sure breakers are tripped in the circuit to which the saw will be connected. Make sure you put a warning placard on the fuse holder or circuit breaker to prevent accidental electrical shock.

2. If you are using hard-wired connections to a junction box, connect the wires in the box, and close the box.

3. Install the fuses or reset the breakers.

4. The saw is now ready for service.

Operating Instructions

CAUTION: Remove all saw frame shipping

materials before operating the machine for the first time.

Complete the following steps at first saw startup:

• Set angle indicator reference and adjust for desired cutting angle.

• Fill coolant reservoir with coolant. Fill hydraulic reservoir with hydraulic oil

• Check saw blade tension.

• Verify tooth ratio and cutting speed adjustment are adequate for material to be sawed.

• Verify that material is fed (must lie on machine worktable) and clamped correctly.

Operating Controls

Control Panel

The machine operating controls are located on a control panel on the top of the electrical enclosure.

All operating controls are mounted on the control panel with the exception of the hydraulic pressure gauge and the saw frame feed rate control that are mounted on the right side of the enclosure (see

Saw Frame Tilt Rate Valve (A1)

The saw frame tilt rate valve is used to set the rate at which the saw frame will move to the desired position.

Saw Frame Feed Rate Control

The saw frame feed rate is set using a feed rate valve mounted on the right side of the electrical enclosure (see Figure 3). The valve knob is turned counterclockwise to increase the feed rate and clockwise to decrease the feed rate.

Hydraulic Pressure Gauge

A pressure gauge is mounted on an angular bracket on the right side of the electrical enclosure (see

Figure 3). The gauge provides hydraulic pressure.

Hydraulic Fluid Level

The level of the hydraulic oil in the reservoir can be viewed through an opening on the left rear corner of the machine (see Figure 4). The level in the reservoir should be maintained no lower than 3/4 the height of the reservoir for proper operation.

Saw Frame Tilt Angle Indicator

The saw frame angle indicator is located at the front center of the machine (see Figure 5). The indicator consists of a disk that has an angle scale on its outside diameter. The disk is attached to the rocker mechanism that supports the saw frame and therefore moves when the saw frame angle is changed.

Adjustments

The efficient operation of the cut-off saw is dependent upon the condition of the saw blade. If the performance of the saw begins to deteriorate, the first item that you should check is the blade.

If a new blade does not restore the machine’s cutting accuracy and quality, refer to the Trouble-

shooting section (or the blade manufacturer’s guide) for conditions to consider and adjustments that can be made to increase the life of the blade.

To change the blade, refer to Replacing Blades in the Maintenance section. To adjust the blade tracking, refer to the following procedures.

Figure 6. Adjustment of Blade Guide Support

Adjusting Blade Guide Inserts

The blade guide inserts installed in the blade guide assemblies are subject to wear and will periodically require adjustment. Adjust the blade guide inserts as follows:

Note: The item references in the following procedures correspond to the item numbers in the corresponding exploded view for the blade guide assembly in the Replacement Parts section.

1.

Loosen the two screws (14) securing inserts

(3). The inserts can be moved laterally as needed.

2.

Move one of the inserts (3) until it contacts the side of the saw blade. Do not deflect the blade.

Tighten the corresponding screw (14).

3.

Move the other insert (3) into contact with the blade. Hold the inserts in that position while tightening the second screw (14).

Place the stock between the vise jaws and clamp tightly. Observe the recommendations for clamping workpieces of different shapes (see Figure 9.)

Blade Tensioning Adjustment

When changing the saw blade or when replacing blade drive components, it will be necessary to adjust the tension on the saw blade. Blade tension is adjusted using the handwheel at the top of the saw frame. Turning the handwheel clockwise tightens the blade. Turning the handwheel counterclockwise reduces blade tension.

The blade tension mechanism has a visual indicator of blade tension. The blade should be tightened until the tab on the indicator is aligned with the scribe mark on the tension assembly (see Figure 7).

Blade Tracking Adjustment

Blade tracking has been tested at the factory.

Adjustment is rarely required when the blade is used properly or if the blade is correctly welded. (See

Figure 7 for location of blade tracking adjustment screws.)

Factory or Field Procedure

1. Start the saw drive motor.

2. Loosen the knobs securing the blade covers.

3. Remove the blade guards from the guide bearing support.

4. Remove both blade guide bearing brackets.

NOTE: Maintain proper tension at all times using the blade tensioning mechanism (see Blade

Tensioning Adjustment).

5. Be prepared to adjust the threaded adjustment pins in the blade tensioning mechanism (see

Figure 7).

CAUTION: WHILE PERFORMING THE FOLLOW-

ING, KEEP THE BLADE FROM RUBBING EXCES-

SIVELY ON THE SHOULDER OF THE WHEEL.

EXCESSIVE RUBBING WILL DAMAGE THE

WHEEL AND/OR THE BLADE.

6. Start the saw. Slowly turn the two adjustment pins at the rear of the tracking mechanism to tilt the idler wheel. Do not turn the other two adjustment pins. Alternately turn the adjustment pins in small increments until the blade is touching the shoulder of the idler wheel.

7. Alternately turn the adjustment pins in small increments so the blade starts to move away from the shoulder of the wheel — then immediately turn the adjustment pins in the other direction so the blade stops moving across the wheel, then moves slowly toward the shoulder.

WARNING: KEEP FINGERS CLEAR OF THE

BLADE AND WHEEL TO AVOID INJURY.

8. Turn the adjustment pins to stop the motion of the blade on the wheel as it gets closer to the wheel shoulder. Put a 6-inch length of paper between the blade and the wheel as shown in

Figure 10. The paper should not be cut as it passes between the wheel shoulder and blade.

NOTE: Turning the screw inward causes the blade to move toward the shoulder of the wheel. Turning the screw outward causes the blade to move away from the shoulder.

9. Turn the adjustment pins a small amount. Repeat the insertion of the paper between the wheel shoulder and the blade until the paper is cut in two pieces.

NOTE: You may have to repeat the check with the paper several times before the blade and the shoulder cuts the paper into two pieces. Do not hurry the adjustment. Patience and accuracy here will pay off with better, more accurate, quieter cutting and much longer machine and blade life.

10. When the paper is cut, turn the hex adjustment screw slightly in the counterclockwise direction.

This assures that the blade is not touching the shoulder of the wheel.

11. Shut off the saw.

12. Hold the hex adjustment screws with a wrench and tighten the jam nuts. Make sure the hex adjustment screws do not move while tightening the lock nuts.

13. Close the saw head cover.

Verifying Cutting Accuracy

Test cuts can be used to determine whether or not you have adjusted the blade accurately. Use 2-inch round bar stock to perform these test cuts, as follows:

1. With the bar stock securely clamped in the vise, make a cut through the bar stock (see Figure

11.)

2. Mark the top of the bar stock.

3. Move the bar stock about 1/4-inch past the blade so you can begin a second cut.

4. Rotate the bar stock 180 degrees so the mark you made is now at the bottom of the cut.

5. Make a cut through the bar stock.

6. Use a micrometer to measure the thickness variation of the disk you have cut from the bar stock. Measure at the top and bottom of the disk.

7. The saw blade can be considered correctly adjusted when the variation is no more than

0.012 inch across the face of the disk.

If you do not have a piece of 2-inch bar stock available for a test cut, use a larger diameter test piece rather than a smaller one. The maximum thickness variation on any test piece should be no more than 0.003 inch per side, per inch of stock diameter.

Band Saw Operation

Before switching on the saw motor, make the following adjustments:

•

Use a saw blade with adequate tooth spacing

•

Adjust blade speed and feed rate.

BECAUSE OF SAW BLADE TOOTH BREAK-

AGE, DO NOT CONTINUE CUTTING IN THE

SAME CUTTING CHANNEL WITH A NEW SAW

BLADE. THE NEW BLADE COULD BE DAM-

AGED BY THE REMNANTS OF THE BROKEN

TOOTH. REMOVE ANY BROKEN TEETH STILL

IN THE CHANNEL.

•

NEVER MOVE THE SAW BLADE ABRUPTLY

INTO THE MATERIAL. DOING SO WILL

REDUCE THE SERVICE LIFE OF SAW

BLADE.

•

IF THE SAWING OPERATION WAS INTER-

RUPTED, RETURN THE SAW FRAME TO

THE BACK OF THE MACHINE BEFORE

CONTINUING THE SAWING OPERATION.

•

ALWAYS PERFORM A RUN-IN ON NEW SAW

BLADES. DOING SO WILL INCREASE

SERVICE LIFE OF SAW BLADE.

•

NEVER USE DULL SAW BLADES. USE OF

DULL BLADES WILL PRODUCE POOR AND

INACCURATE CUTTING.

Tips for Optimum Sawing

Saw Blade Teeth Breakage

Each tooth of the saw blade can only withstand a defined cutting force which varies depending on blade quality. If this limit is exceeded, the tooth will break.

Overcharging of chip space happens when larger cross sections are sawn with fine-spaced saw blades (such as cutting a 4-inch diameter workpiece with a 10 Z/inch saw blade) and high feed rates.

In some cases, fine-spaced saw blades can be used to saw larger cross sections. However, a lower feed rate must be used.

Breaking of Teeth Results from:

• Sawing thin wall profiles with a blade that has tooth spacing that is too large or by using feed rate that is too high.

• Feed rate too fast or saw blade touching material before starting saw motor.

Saw Blade Life

The saw blade can become prematurely dull if you do not match the blade to the material, if you select too high a cutting speed, or if you do not use any coolant. If the cutting speed is too high, the saw blade teeth will become dull due to overheating.

Overheating the tips of the teeth can also occur when the saw blade slides across the workpiece with little or no chip removal (results in poor heat transfer because only the tooth tips contact the material).

Feed Rate for Changing Profiles

When sawing profiles such as tubes, the cross section being cut changes continuously as the blade cuts through the tube. Initially it is like a piece of solid round stock. When it breaks through the wall of the tube, the blade is contacting the two sides of the tube. For sawing operations involving changing profiles, we recommend using multiple pitch blades.

The feed rate used on changing profiles should not be made too fast. The rate should be even lower with differing cross section profiles in order to avoid tooth breakage.

Flat Iron

Most tooth breakage occurs when cutting flat iron, often from spacing that is too fine. By clamping flat iron a bit diagonally, you can saw with fine spacing because the cross section is reduced by the diagonal position of the flat iron.

Saw Blade Selection

Selection of the correct saw blade for various materials is very important. Following are some tips for determining the saw blade to use:

• Refer to the upper chart in Figure 12. When cutting many different kinds of materials and cross sections, we recommend using saw blades with spacing of 4 Z/inches (shape of tooth N) and spacing of 8/12 Z/inches (multiple pitch spacing).

• Saw blades with 4 Z/inches can be used for solid material of 0.75 inch to 8.00 inches and profile bars from 0.25 inch and higher. Multiple pitch spacing of 8/12 Z/inches is used for solid material of 0.08 inch to 6.00 inches and profile bars from 0.5 inch to 2.0 inches.

• As a rule, we recommend the use of high quality bimetal saw blades so that all materials mentioned can be sawn (in particular, if there are hardened blow holes) and fewer saw blade replacements will be required.

• In some cases, however, it might be less expensive to use saw blades of special quality. This applies if constant tooth breakage is a problem.

• In order to take advantage of full machine capabilities, such as when sawing larger quantities of the same materials and cross sections, select the optimum spacing, shape of tooth and highest quality saw blade possible.

• If you are not sure which saw blade to use for a particular application, contact your dealer for help.

Tooth Profile

Standard Tooth (N) Effective cutting angle is zero

(0) degrees. Suitable for sawing most types of cast iron and steel.

Claw Tooth (K) Effective cutting angle 10 degrees. Suitable for free machining materials, such as non-ferrous metals or low strength steels.

Multiple Pitch (C) Variable spacing with different shapes and depths of teeth.

Available only in bimetal. Suitable for all materials and frequently changing cross sections/profiles.

Figure 12: Table for Spacing and Shape of Tooth

Maintenance

WARNING: THE MAIN SWITCH OF THE MACHINE

MUST BE OFF AND POWER DISCONNECTED

WHEN PERFORMING MAINTENANCE. ALL WORK

MUST BE CARRIED OUT BY QUALIFIED AND

AUTHORIZED PERSONNEL. VERIFY THAT ALL

PROTECTIVE DEVICES HAVE BEEN REINSTALLED

AND NO UNAUTHORIZED PERSONNEL ARE THE

IN THE AREA OF THE MACHINE BEFORE POWER

Daily Maintenance

• Check coolant level daily. Replenish coolant if level is less than 1/3 full.

• Apply a thin film of oil to the vise spindle, vise rails, and other unpainted surfaces.

•

Keep machine free of sawing debris and chips.

Empty debris accumulated in chip tray.

Hydraulic Oil Checks

During the first week of operation (about 50 operational hours), check level of hydraulic oil in reservoir. Also check all hoses and fittings for leaks. After this initial period, perform the checks weekly.

CAUTIONS:

• REPLACE DAMAGED PARTS (ESPECIALLY

HOSES) IMMEDIATELY.

• FILL OIL TO MAXIMUM LEVEL AT EVERY

CHECK.

• TIGHTEN LOOSE SCREWS, BUT DO NOT

EXCEED TORQUE.

• WHEN ADDING FLUID OR COMPLETING ANY

HYDRAULIC INSTALLATION, BE VERY

CAREFUL TO MAINTAIN CLEANLINESS,

ESPECIALLY WHEN PIPES OR CONTAINERS

ARE OPEN.

• USE ONLY HYDRAULIC OIL OF VISCOSITY

32 TO 46 ACCORDING TO DIN 51519 AND

QUALITY HLP (E.G. SHELL-TELLUS 32).

Maintenance After First Week

1. After the first 50 operational hours, all terminal connections in the switch cabinet should be checked and re-tightened.

2. Clean coolant reservoir.

3. Check chip brushes for wear.

4. Change hydraulic oil and filter after first 50 to

100 operational hours. After that, change the oil and filter every 2,000 operational hours or a minimum of once a year.

CAUTION: IF OIL AND FILTER CHANGES ARE NOT

PERFORMED (ESPECIALLY AFTER THE FIRST 50

TO 100) OPERATIONAL HOURS, THE SOLENOID

VALVES MAY FAIL FROM THE DIRTY OIL. THE

WARRANTY WILL BE VOIDED IF THE SOLENOID

VALVES FAIL DUE TO DIRTY OIL. WHEN ADDING

HYDRAULIC OIL AND/OR CHANGING THE FILTER,

CHECK FOR DAMAGE OR LEAKS.

Every 100 Hours

Check, and if necessary, adjust saw blade guides

(see Adjusting Blade Guide Inserts).

Every 1,000 Hours

1. Lubricate linear guide rails (see Lubricating

Linear Guide Rails).

2. Clean entire machine and dispose of chips and saw debris. Remove debris from the drive, the saw blade, the guide rails, and from the coolant reservoir. (Take special care that linear guides of the saw frame are cleaned of debris and dirt every time the blade is replaced.)

3. Dispose of dust and coolant separately.

4. Verify that all adhesive labels are legible. If not, replace the labels immediately.

5. Protect electrical components such as motors, switches, and switch cabinet components, from moisture during cleaning.

WARNING: NEVER USE FLAMMABLE SOL-

VENTS OR CLEANING AGENTS THAT COULD

EMIT DANGEROUS VAPORS.

Lubricating Linear Guide Rails

Every 1000 hours, apply a thin coating of general purpose grease to upper and lower rails and the corresponding guide blocks.

Hydraulic Oil Level

Check hydraulic oil level daily (see Figure 4). The hydraulic oil level should be a minimum of 3/4 full.

Coolant Level

Check the coolant level daily. The coolant level should be a minimum of 1/3 full.

Hydraulic Oil and Filter Change

Change the oil every 1000 hours by removing the reservoir drain plug. Change the hydraulic filter whenever the oil is changed.

Replacing Saw Blade

WARNING: ALWAYS WEAR LEATHER GLOVES

WHEN HANDLING SAW BLADE TO AVOID

INJURY FROM THE SAW TEETH.

Saw blade replacement is one of the most dangerous procedures performed on the band saw, since the sharp teeth of the saw blade are completely unprotected. This work must be completed by authorized and trained personnel only.

Use the following procedure for saw blade replacement:

1. Switch off band saw motor and move saw frame into rearmost position.

2. Put saw frame in right tilt of 7 to 7-1/2 degrees to the right.

WARNING: ALWAYS TURN OFF MAIN POWER

SUPPLY TO THE MACHINE AND WEAR WORK

GLOVES WHEN REPLACING THE SAW BLADE.

3. Disconnect main power switch.

4. Loosen upper blade guide support locking handle. Push support down until saw blade cover can be tilted forward.

5. Open upper and lower blade wheel covers.

6. Loosen saw blade tensioner as far as possible.

7. Loosen chip brush locking screw (10). Turn chip brush completely to the right.

8. Push saw blade forward out of the guides with one hand and hold the blade with the other hand so that blade does not engage (see Figure 13).

9. Remove saw blade from the machine. Hold saw blade firmly with both hands.

10. Hold saw blade (see Figure 14) with both hands. Wind the blade into a roll and fasten with a length of wire.

11. Clean debris from the saw blade guides and the linear guides.

12. Check condition of chip brush. Adjust or replace if necessary.

Figure 17. Removing Saw Blade

Figure 14. Holding Saw Blade

Installation of Saw Blade

WARNING: HOLD SAW BLADE FIRMLY WITH

BOTH HANDS AND NEVER RELEASE THE

BLADE DURING INSTALLATION!

1. Hold the saw blade away from your body and feed it slowly into place.

2. Check saw blade teeth direction. Teeth must face the same direction the saw blade will run. If not, change teeth direction by “twisting” the saw blade.

3. To reverse the direction of the teeth, grasp the upper third of saw blade tightly between thumbs and forefingers of both hands, with thumb at the outside of the saw blade. Then twist saw blade by turning both hands in the same direction.

4. Insert saw blade into the saw.

5. Move it onto the drive wheel, then push it upwards from below into the saw frame and move it onto the idler wheel. Now push the saw blade into the lower guide, and then into the upper guide. The saw blade will have to be turned 90 degrees.

CAUTION: THE BACK OF BLADE (NOT THE

TEETH) MUST BE BELOW THE STOP COLLAR

OF THE TENSIONING AND DRIVE ROLL. TEETH

MUST FACE FORWARD BETWEEN THE GUIDES!

6. Tighten saw blade slightly using the tension handwheel and check seating of saw blade. If necessary, correct seating of saw blade by pressing against stop collar and pushing the blade into the guides.

7. Put the chip brush back into its original position and tighten screw (10).

8. Turn the tension handwheel until proper tension is achieved. Use of a blade tensioning gauge is recommended.

9. Close idler and drive wheel covers.

10. Adjust position of guide support and tighten the locking handle.

NOTE: Each new saw blade should be run-in by reducing the feed rate to 2/3 for the first 300 cm².

Cleaning

1. Clean off any preservative on machine surfaces.

2. After cleaning, coat the machined surfaces of the cut-off saw with a medium consistency machine oil. Repeat the oil coating process at least every six months.

3. Clean up accumulated saw cuttings after use.

Make sure the lead screw is kept free of saw cuttings and other material that would cause damage.

4. Clean the chip sludge from the coolant tank.

The frequency should be determined by how often the saw is used.

Lubrication

Lubricate the following components at the specified frequencies and using the lubricants defined below:

1. Ball bearings: the bearings are lubricated and sealed—periodic lubrication is not required.

2. Blade guide bearing: the bearings are lubricated and sealed—lubrication is not required.

Inspect periodically.

3. Idler wheel bushing: the bearings are lubricated and sealed—lubrication is not required. Inspect periodically.

4. Slide rails: lubricate with light oil monthly (see

Emergency stop switch actuated

Saw shuts down during operation

Saw motor overloaded

Coolant supply does not operate

Short saw blade life

(teeth dull)

Broken tooth

Main fuse or circuit breaker trips

Loose power cable

Saw blade cover open (limit switch interlock tripped)

See Saw Does Not Start above.

Motor circuit breaker trips.

Possible Remedy

Reverse phases of connections

Reverse phases or connections

Determine reason E-stop tripped.

Reset E-stop

Check

Check

Close and tighten knob on covers

See above

See Saw Motor Overloaded

Motor air flow screen obstructed

Coolant reservoir empty

Coolant valve closed

Coolant valve clogged

Coolant supply hose kinked or clogged

Air in the system

See Saw Motor Overloaded or

Coolant Pump Overloaded

Replenish reservoir

Open valve

Remove clog

Replace or clean hose

Bleed air by removing and reinstalling pressure hose.

Select compatible bi-metal blade

Select blade with correct ratio

Blade not compatible with material being cut

Wrong tooth ratio causes broken tooth

(dulling other teeth)

Coolant not being used

Cutting speed too high

Saw blade gullet filled with debris

Adjust coolant flow/use correct coolant for material being used

Reduce speed

Use saw blade with a different tooth ratio, or reduce feed rate, or use a different clamping method (especially with flat steel)

.

Troubleshooting

(Continued)

Fault

Does not cut straight

Stock not cut at right angle or is not parallel

Blade stops sawing but motor continues to run

Probable Cause

Blade guide too far from workpiece

Saw blade dull

Feed rate too high

Saw blade teeth not evenly set

Saw blade not correctly adjusted

Stock not evenly clamped for cutting

Vise jaws not square (not 90 degrees to the saw blade)

Material support stand not aligned with machine

Drive wheel defective

Saw blade comes off drive or idler wheel

Tracking or tensioning out of adjustment

Possible Remedy

Set blade guides closer to workpiece

Replace blade

Reduce feed rate

Replace blade

Adjust saw blade

Insert and clamp workpiece correctly

Set jaws at 90 degrees

Align material to vise bed

Disassemble drive wheel components and check for damaged parts

Readjust tensioning and tracking
