Serious injury or death may occur if minimum safety precautions are not understood, and obeyed by operators and those other persons who may be in the immediate vicinity of the subject equipment. Persons who operate or are in the immediate vicinity of the subject equipment must be properly trained in, and use, minimum safety precautions and procedures for such machinery.

PERSONAL PROTECTION EQUIPMENT, SUCH AS GRINDING GLOVES, HEARING PROTECTION, AND SAFETY GLASSES MUST BE WORN WHEN USING THIS EQUIPMENT. CHECK WITH YOUR COMPANY’S SAFETY OFFICER FOR OTHER SAFETY REQUIREMENTS.

NEVER USE THIS EQUIPMENT IF YOU ARE NOT PROPERLY TRAINED IN ITS OPERATION AND SAFE USE! IF IN DOUBT STOP AND ASK FOR GUIDANCE!

MINIMUM SAFETY REQUIREMENTS TO OPERATE, OR WORK IN THE IMMEDIATE VICINITY SUBJECT EQUIPMENT:

1.Read and understand all operating instructions, manuals, labels, and other information provided with the equipment.

2.Install the equipment according to manufacturer’s instructions.

3.Electrical installation must be in accordance with applicable codes and regulations.

4.Securely bolt the equipment to a rigid, structurally sound mounting surface.

5.Don’t expose the grinder to rain, or use the grinder in damp or wet locations. Don’t use the grinder if the power cord is damaged or wet.

6.Do not wear loose clothing or jewelry. Non-skid footwear is recommended when working with the grinder. Wear protective hair coverings to contain long hair. Wear proper safety equipment and clothing to protect eyes, hands, face, arms, legs, feet, and body from ying debris, forcibly ejected work pieces and broken abrasive belts.

7.Use safety glasses. Everyday eyewear does not have impact resistance lenses.

8.Do not use this equipment when tired, ill or under the in uence of alcohol or other drugs.

9.Review and understand all machine guards, adjustments, and points of exposure to potential injury.

10.Do not remove, tamper with, or otherwise alter, equipment guards and other safety features.

11.The use of stone or vitreous wheels on any OREGON belt grinder is prohibited. The grinder guarding

is not suitable for these types of wheels.

12.Ensure the machine is adjusted and remains adjusted according to manufacture’s requirements.

13.Maintain the equipment in good operating condition.

14.Have another person who is knowledgeable in proper and safe operation of the subject equipment demonstrate proper and safe operation to all operators, and to those persons who might be in the immediate vicinity of the subject equipment.

15.Always wear gloves and use work piece holding devices when ever possible that diminish the possibility that persons will come in contact with moving machine pieces, or spark/debris output from the machine.

16.Always keep electrical cords clear of rotating parts and belts when in motion.

17.Do not use the grinder near ammable liquids or gases. Sparks from the grinder can cause res.

18.Use spark and debris arresting apparatus. Such apparatus should be connected to the machine so as to contain dust and debris that is generated, and to suppress sparks thereby limiting human inhalation risk, and the risk of re or explosion.

19.Use appropriate inhalation apparatus to protect person from ingestion and/or inhalation of sparks, debris, smoke, particulates, etc.

20.Avoid mixing di erent metals, alloys, and materials. To mix such materials might create a re or explosion hazard.

21.Protect persons from work pieces, particulates, etc. that could be forcibly ejected from the machine. For example, a bu ng wheel or grinding belt can “grab” a work piece while the work piece is being bu ed, polished, ground, or otherwise conditioned, resulting in forcible ejection toward the operator or those in the vicinity of the machine. The use of leather aprons, gloves, and eye shields are examples of protective gear that may be e ective. In general do not grind, bu , or otherwise engage the traveling belt, wheel, or disc surface with the work piece pointing into

the direction from which the belt, wheel, or disc is traveling. However, if you choose to do so, be aware the work piece may lodge in the traveling belt, wheel, or disc and be forcibly and dangerously ejected.

22.Do not operate this machine if the gap (nip point) between a moving belt, wheel or disc, and the work support surface exceeds 1/8 inch.

23.Do not operate this machine if the gap between the moving abrasive belt, disc or wheel and the adjacent face of the work rest (or table) will permit passage of the work piece through the gap (nip

Safety Requirements

point). Note, however, that certain alloys such as titanium may create conditions where grinding debris can accumulate in a tight gap creating a potential re hazard. When in doubt consult with your safety o cer. Failure to observe this warning may result in the work piece or other item being caught in this gap, and/or being forcibly ejected. Failure to heed this warning may cause serious bodily harm to the operator and/or bystanders.

24.Never position the work rest table at an acute angle between the top of the work rest table and the moving belt or wheel. Doing so will create “nip point” that can cause serious injury should an operator body part become entangled (pulled into) the nip point created by this acute angle.

25.Do not operate the equipment or allow others to operate the equipment without proper training in these and other rotating machinery safety requirements.

26.Disconnect the power source when the grinder is not in use.

27.Do not perform maintenance on the equipment unless you are fully quali ed to do so and understand all necessary safety and operating requirements.

28.Do not leave the machine unattended while it is running.

29.Correct equipment or safety problems immediately. Do not operate the equipment when it requires maintenance or correction.

30.Install and use high quality abrasive belts, wheels, discs, media, etc., as appropriate to your machine.

31.Understand and follow the operating requirements provided by the manufacturer of these materials.

Before Use

BEFORE OPERATING ANY EQUIPMENT PLEASE READ AND REVIEW ALL SAFETY INSTRUCTIONS FOR THE OREGON® MODEL 760.

PERSONAL PROTECTION EQUIPMENT, SUCH AS GRINDING GLOVES, HEARING PROTECTION, AND SAFETY GLASSES MUST BE WORN WHEN USING THIS EQUIPMENT. CHECK WITH YOUR COMPANY’S SAFETY

OFFICER FOR OTHER SAFETY REQUIREMENTS.

WARNING:

USE CAUTION WHEN LIFTING GRINDER. USE TWO PEOPLE WHEN REMOVING FROM SHIPPING BOX.

Prior to operating the model 760 please take time to do the following:

1.Ensure that you have received all of the items that you ordered. Compare the packing slip with your purchase order, and of course with the physical items received.

2.Verify that there is no obvious shipping damage. If shipping damage is discovered notify the freight carrier of your intention to le a freight damage claim. They will assist you.

3.Verify that the AC power that is identi ed on the machine as received matches the AC power that you intend to operate the machine with. Do not modify the machine’s wiring without rst contacting your distributor and/or OREGON.

The model 760 belt grinder is a three wheel path belt grinder that uses a 1 1/2" x 60" continuous loop abrasive belt. For maximum e ectiveness and operator safety, use abrasive belts manufactured by well respected abrasive manufacturers.

4.Do not modify or defeat any AC wiring safety feature. Never remove the grounding pin on the AC plug.

5.Verify that you have received an Instruction Manual.

6.Verify that the various guards for the machine are in place and functional. (See illustration, pg. 5.)

a.The contact wheel guard and vertical platen are mounted and adjusted such that the platen lightly touches the back of the abrasive belt (Figure 1).

See page 7 for complete instructions on installation.

b.The full safety guard is in place, closed, and its door latch is functional such that it will securely hold the safety door closed. (Figure 2).

7.Prior to operating the model 760 carefully read the Instruction Manual. Ensure that all persons who will operate the model 760, or who will work in the vicinity of the model 760 read understand, and comply with these instructions.

Use abrasive belts that are the proper size and type for your machine.

•Do not use abrasive belts that are old or excessively worn.

8.Ensure that the grinder is located in an area that provides clear access to the machine such that operators have safe and unobstructed access to the machine. The work place should be free from oor obstructions, trip points, and other faults that may reduce operator safety.

9.OREGON recommends that all three phase installations include a magnetic starter. Magnetic starters protect motors from “single phasing”, overheating, etc. thereby reducing the risk of damage to the equipment and/or re hazard to your facility.

10.Ensure that the model 760 AC power source is properly sized, and properly fused. You should consult a competent electrician, or you may call OREGON for guidance.

•Do not use abrasive belts that use lap splice joints. Lap spliced belts are prone to separation. They may also tend to snag your work and create a potential safety hazard by snagging and propelling the work part in the operator’s direction.

MOUNTING

Your machine has been assembled and passed numerous quality checks prior to shipping. The mower blade attachment is fully assembled.

1.Open wheel cover door and remove contact wheel with 15/16" socket wrench. (Figure 3)

2.Rotate table support arm to the down position.

3.Using a 7/16" wrench and 5/32" Allen wrench, remove table support arm bolt and attach the support bar to the table support arm.

4.Using a 3/16" Allen wrench, tighten table support arm bolt.

5.Using a 3/16" Allen wrench, remove two screws from table support arm mounting block and attach mower blade support table. Tighten securely, making sure to place washers on the outside of bracket on mower blade support table. (Figure 4)

6.Replace contact wheel with 15/16" socket.

It will be a tight t, so proceed carefully and use a little lubricating oil if needed.

INSTALLING THE BELT

7.Install the 36 grit belt over all three wheels and tension belt by pivoting tension knob upwards.

8.Pivot vertical platen into position so belt is gently touching the vertical platen. Tighten the 3/16" Allen screws to secure the vertical platen to the bearing housing.

9.Ensure that the abrasive belt is tensioned properly. To do this, raise the tensioning handle (Figure 5). You will hear mechanical clicks as the tensioning ratchet moves. Generally, the belt will be adequately tensioned when you hear three to eight clicks. To reduce or release the belt tension slightly raise

the tensioning handle then press the button in the center of the tensioning handle. Move the tensioning handle down slightly to reduce belt tension or all the way down to release belt tension.

10.Rotate belt by hand to center belt on wheels.

11.Close wheel cover door.

12.Attach chain saw bar grinding table with two bolts to the vertical platen. (Figure 6).

ADJUSTING THE ATTACHMENT

Unlike a stone grinder, the diameter of the contact wheel will remain nearly the same the entire life of the wheel. Since the diameter of the wheel also will remain constant you will rarely need to adjust the table height. Another advantage of using a belt to grind metal versus a stone is when a stone reduces in diameter, you lose surface speed, making grinding times increase. A stone wheel may turn at 6,000 surface feet per minute when it’s brand new, but after limited use the diameter of

the stone will decrease and the result will be increased sharpening times and the stone will retain more heat.

Operation

CHECKING THE GRINDER

The model 760 was fully tested and veri ed to comply with requirements prior to shipping from the factory. You should perform the following steps:

1.Adjust the work support and work support arm to the desired position with the Attachment Locking Lever (Figure 7). Take care that the gap between the face of the abrasive belt and the work rest

is at most 1/8 inch. WARNING: Be aware that thin section work pieces can pass through this gap if the gap is not properly adjusted. Ejected work parts can cause serious personal injury!

2.With the machine securely bolted to its table, pedestal, and/or oor point connect the AC power to its source.

3.Engage the motor by placing the ON/OFF switch to ON. The belt should rotate smoothly in a

counterclockwise direction around the machine wheel belt path. If either of these conditions is not met immediately turn the machine OFF.

a. If the abrasive belt does not remain centered on the contact wheel while the belt is moving use the Tracking Adjustment Knob (Figure 8) on the upper left side of the machine to track the belt. Turn this control clockwise to cause the belt to track to the left; conversely, turn the control counterclockwise to cause the belt to move to the right.

b.If the belt runs in reverse (up from the oor) you must correct this unsafe condition by changing the main drive motor rotation direction. (See instructions below.)

c.If the abrasive belt tensions and tracks properly,

but has excessive vibration, turn the machine o and call OREGON® for assistance.

Always unplug the machine before performing any adjustments to the work platforms.

Operation

MAINTENANCE

•Every thirty days apply light machine oil to the rear wheel support and the Tension Arm Interface. (Figure 9) Two drops of oil is su cient.

•Every thirty days check the v-belt tension. If you can hear the belt “slap” the V-belt Guard (Item 4, page 5) when the drive motor starts, the v-belt requires re-tensioning. Do this by loosening the four bolts (Figure 10) that secure the motor to the machine base and slide the motor toward the rear of the machine. Tighten the four bolts.

•Vacuum daily or otherwise remove dust and debris build-up from the machine and the machine belt track.

There are no other maintenance actions required. All bearings are sealed for life and require no additional lubrication.

Operation

ALIGNING IDLER WHEELS

When idler wheels are removed and/or replaced they must be installed such that they are in proper alignment. Failure to properly align the idler wheels will result in premature failure of the wheels. Premature failure will be evidenced by outer diameters being excessively worn such that the wheels lose their factory crown, wear to a truncated form, or become out of balance. Misalignment

results in wear that is analogous to front tire wear when the front steering mechanism of an automobile is misaligned. The upper idler equates to the front wheels of the car. If either idler wheel is misaligned to each other or to the contact wheel, excessive and irregular wear will occur.

The upper and rear idler wheels must operate in the same plane. This means that when they are correctly aligned a plane passing through the radial center of the upper wheel will exactly pass through the radial center of the rear wheel. Machines are shipped from the factory with wheels of the same width. Currently, model 760 machines are shipped with wheels that are 1.5 inches wide. The model 760 also has available contact wheels 0.5, and 2.0 inches wide, along with corresponding belts. Contact your OREGON® distributor for details.

1.Disconnect electric power and remove the abrasive belt.

2.Install the rear idler such that its inside bearing surface is approximately 0.06 inches out from the wheel support. Secure the wheel with locking set screw. (Figure 11)

3.Install the upper wheel such that its inner bearing surface is approximately 0.06 inches out from its bearing support. Secure the wheel with locking set screw. (Figure 12)

4.Loosen the retaining nut that locks the upper idler wheel adjusting screw. (Figure 13) Using screw adjust the upper idler wheel until a straight line representing the plane passing through the center of the upper idler exactly passes through the center of the contact wheel. This line represents the center of belt travel. Note: make certain that the bearing support is against the screw end.

5.Project a line from the upper idler outside rim to the outside rim of the rear idler. Adjust the tracking adjustment knob until the wheels are exactly planar. That is, their radial centers are aligned.

6.Repeat step 3 and 4 until both conditions are satis ed. That is, the upper and rear idlers are aligned to each other and both wheels are aligned to the contact wheel.

7.Tighten the locking nut on the upper idler wheel adjusting screw.

8.Install a new abrasive belt. Roll the belt manually to assure that it will maintain coarse tracking. If the belt does not track manually, repeat the prior steps until it does. If after repeating these steps the belt still will not track, the machine requires other

maintenance and/or one or both idler wheels require replacing. The wheels should be replaced in pairs.

9.Apply electric power to the machine and verify that the tracking adjustment knob (Item 9, pg. 5) will sweep the belt across the face of

the contact wheel. At least ½-inch adjustment in both directions from center should be possible.

Lawn Mower Blade Sharpening

SHARPENING

Mower blades

Free the blade of any grease, dirt, or clippings prior to sharpening. Check the blades to make sure they are not bent or cracked.

Using a blade balancer, check the blade for its balance. When sharpening start by grinding the light end of the blade and then follow with the heavy end.

Move the blade in one direction only. Assuming that you have a standard mower blade, your direction would be from left to right. Rest blade on table, gently move blade into rotating wheel and draw the blade to the right. Multiple passes are required to achieve the edge desired. Minimal pressure to the contact wheel is

recommended. The idea is to have the belt do the cutting, not by using force against the contact wheel. Make

rapid passes, each pass should only take seconds in total time. If you are not moving the blade across the wheel in a rapid fashion, you will create hot spots in the blade, and the blade will not move easily across the wheel.

After sharpening the rst edge, use the slack area of the belt to remove any burrs that may have been created in the sharpening procedure. Next, move to

the second edge and repeat the procedure. Check the balance of the blade to ensure proper stock removal.

Mulching blade sharpening

Remove the vertical platen by removing the two Allen bolts that attach it to the contact wheel guard. It is important to

readjust the contact wheel guard to remove the pinch point created by removing the platen. By removing the platen you create a large “slack” free belt area. By using a exible back belt (J weight) or a narrow sti back belt you will be able to use the slack area to sharpen the blade. The operator will freehand the desired angle. After sharpening the rst edge, use the slack area of the belt to remove any burrs that may have been created in the sharpening procedure. Next, move to the second edge and repeat the procedure. Check the balance of the blade to ensure proper stock removal.

Rotary-style o set ail blade sharpening

Free the blade of any foreign

substances. Depending on style of the blade, balancing the blade

maybe di erent than described in this manual. Most rotary blades can be balanced using a simple balance-style scale. Since there is no other way to check for balance due to the o set hole style of the blades, use of a scale is to make sure that the blades are all equal in mass. Using a scale allows you to make sure each blade weighs the same amount, keeping the blades in balance.

You may also choose to check the blades using a standard scale. Once again, start with the lightest blade and then sharpen the heavier blade, checking the blades for balance.

WARNING:

If a belt is damaged or shows excessive wear, immediately stop use of the belt and discard it.

Attach the galvanized tubing (Item 1, page 12) to the worktable, using two button head black oxide screws (Item 18, page 12) and two kep nuts (Item 14, page 12). This changes the angle for the rotary-style blade to a factory recommended angle. As with mower blades, it is recommended to move the blade in one direction only. If the blade has deep chips, use the contact wheel to “face the blade.” Move up on the contact wheel a couple of inches to the centerline and run the blade back and forth several times to even the edge of the blade. Next you will rest the blade against the tubing and start the

sharpening process. Again, use only light inward pressure. The belt and speed of the belt will do all the work for you.

Chipper blade sharpening

Free the blade of any foreign substances. Depending on style of the blade, balancing the blade maybe di erent than described

in this manual. Most chippers require all blades to be the same height. Start with the shortest blade and use it for a reference, then move on to the others in the set.

Only sharpen blades that are long and wide enough to safely hold on to. As with any sharpening process on the grinder move only in one direction and apply minimal inward force.

GRINDING BELTS

OREGON recommends using only a 3M or Norton 24 or 36 grit ceramic belts to sharpen blades using the blade attachment. (3M 987FI or Norton Blaze R980.) These belts contain cooling aids and are constructed for heavy stock removal. Replacement belts can

be ordered from your OREGON® distributor.

Remove any burrs on the back of the blade by making a couple of passes on the slack portion of the belt. This will reduce the e ort required when moving the blade across the table.
