1. Use an approved roll bar and seat belt for safe operation. Overturning a tractor without a rollbar can result in death or injury. If your tractor is not equipped with a rollbar and seat belt, see your Tractor Dealer.

2. Equip your tractor with FOPS (Falling Object Protective Structure) before installing or operating loader.

3. Always use seat belt when rollbar is installed. Do not use seat belt if rollbar is removed from tractor.

4. Add recommended wheel ballast and/or rear weight as recommended in owner's manual to provide good stability.

5. Move rear wheels to widest settings recommended to increase stability.

6. Move and turn tractor at low speeds.

LOADER

1. Improper use of a loader can cause serious injury or death.

2. Do not lift or carry anybody on loader, in bucket or on attachment.

3. Never allow anyone to get under loader bucket or reach through lift arms when bucket is raised.

4. Do not walk or work under a raised loader or bucket or attachment unless it is securely blocked or held in position.

5. Avoid overhead wires and obstacles when loader is raised. Contacting electric lines can cause electrocution.

6. Make sure all parked loaders are on a hard, level surface. Engage all safety devices.

OPERATING LOADER

1. As owner of this loader, it is your responsibility to be certain anyone operating this loader has read this manual first to be aware of safe operation of your tractor and loader.

2. Exercise caution when operating any loader with a raised loaded bucket or fork.

3. Avoid loose fill, rocks and holes. They can be dangerous for loader operation or movement.

4. Use care when operating on steep grades to maintain proper stability. Always carry bucket or attachment as low as possible.

5. Allow for loader length when making turns.

6. Stop loader arms gradually when lowering or lifting.

7. Use caution when handling loose or shiftable loads.

8. Carry bucket or attachment at a low position during transport for better visibility.

9. When parking or servicing, lower bucket to ground, stop engine and set park brakes before leaving tractor seat.

10. Operate loader controls only when properly seated at controls.

11. Using front end loaders without special attachments for handling large heavy objects such as large round or rectangular bales, logs and oil drums is NOT RECOMMENDED.

12. Handling large heavy objects can be extremely dangerous due to:

Danger of rolling tractor over.



Danger of upending tractor.



Danger of objects rolling or sliding down loader arms onto



operator.

13. If you must perform this sort of work (see 12 above), protect yourself by:

Use proper attachments only.



Never lift load higher than necessary to clear ground when



moving.  Ballast tractor rear to compensate for load.  Never lift large objects with equipment that does not have

an anti-rollback device.  Move slowly and carefully, avoiding rough terrain.

MAINTENANCE

1. When servicing or replacing pins in cylinder ends, buckets, etc., always use a drift and hammer of non-sparking material. Failure to do so could result in injury from flying metal fragments.

2. Do not modify or alter or permit anyone else to modify or alter loader or any of its components or any loader function without first consulting your Dealer. If you have any questions regarding loader modifications contact your Rhino Dealer.

3. Always wear safety goggles when servicing or repairing tractor or loader.

4. Escaping hydraulic/diesel fluid under pressure can penetrate skin causing serious personal injury.



DO NOT use your hand to check for leaks. Use a piece of cardboard or paper to search for leaks.



Stop engine and relieve pressure before connecting or disconnecting hydraulic or diesel lines.



Tighten all connections before starting engine or pressurizing lines.



If any fluid is injected into skin, obtain medical attention immediately or gangrene may result.

PREPARING TRACTOR PRIOR TO OPERATION

WARNING:

before inspecting, servicing or operating loader and tractor.

INSPECTION

Thoroughly inspect your fully assembled tractor and loader prior to operation.

1. Check all hardware to be sure that it has been properly installed and tightened. Retighten all hardware after 10 hours of initial operation.

2. Check tire pressure. Refer to tractor operator's manual for recommended pressures.

3. With tractor on level surface, compare tractor rear axle height from left to right, measuring from axle center to ground. Adjust air pressure in rear tires until axle height measures same for both sides.

NOTE:

side, cutting edge on loader bucket will not sit flat on ground.

4. Review tractor lubrication schedule and consult MAINTENANCE section of this manual to be certain all pivot points have been properly lubricated.

If rear axle on tractor is not level from side to

Read all operator's manuals

FILLING THE BUCKET

Approach and enter the pile with a level bucket.

Loaders with 1-lever control, ease lever back and away from you to lift and roll back bucket.

Loaders with 2-lever controls, ease both levers back to lift and roll back bucket.

5. Use instructions listed in MAINTENANCE section of this manual to check all hose and tubing connections to insure no leaks are present.

INSTALL COUNTERBALANCE

WARNING:

loader, add sufficient counterweight so a minimum of 25% of total weight of tractor, loader and rated load is on rear wheels when bucket contains rated load and is in maximum forward position.

Sufficient weight can be added to tractor by filling rear

OPERATION

wheels with liquid ballast, installing wheel weights or 3- point hitch counterweight. If 3-point hitch counterweights are used, they should be carried as low as possible at all times to maximize stability. Effective counterbalance weight of mounted rear equipment is determined by multiplying actual weight of equipment by 1.50.

EXAMPLE:

to rear of tractor, multiplied by 1.50, equals 1200 pounds of effective counterbalance weight.

After adding recommended counterweight, weigh tractor at rear axle to be sure counterbalance is adequate.

LIFTING THE LOAD

When lifting the load, keep the bucket positioned to avoid spillage. Loader has mechanical self leveling of attachment in both raise and lower cycle. Attachment can be adjusted by using bucket cylinders.

CAUTION:

excess of loader capacity.

CARRYING THE LOAD

Position bucket just below tractor hood for maximum stability and visibility, whether bucket is loaded or empty.

Do not attempt to lift loads in

When transporting the load, keep bucket as low as possible, to avoid tipping, in case a wheel drops in a rut.

DUMPING THE BUCKET

Lift bucket high enough to clear side of vehicle. Move tractor in as close as possible to side of vehicle, then dump bucket.

LOWERING THE BUCKET

After bucket is dumped, back away from vehicle while lowering and rolling back bucket.

OPERATION

Use extreme care when operating loader on a slope, keep bucket as low as possible. This keeps center of gravity low and will provide maximum stability.

CAUTION:

dangerous. Extreme care is recommended. Keep bucket as low as possible.

Operating loader on a hillside is

F-3778-12-04 Operation Section 4-3

Page 26

OPERATION

OPERATING WITH FLOAT CONTROL

During hard surface operation, keep bucket level and put lift control in float position to permit bucket to float on working surface. If hydraulic down pressure is exerted on bucket, it will wear faster than normal.

Float will also prevent mixing of surface material with stockpile material. Float position will reduce the chance of surface gouging when removing snow or other material, or when working with a blade.

Sidecutting is a good technique for cutting down a big pile.

LOADING FROM A BANK

Choose a forward gear that provides sufficient ground speed for loading.

OPERATION

Exercise caution when undercutting high banks. Dirt slides can be dangerous. Load from as low as possible for maximum efficiency. Loader lift and breakaway capacity diminish as loading height is increased.

If the pile sides are too high and liable to cause cave-in, use loader to break down the sides until a slot can be cut over the top.

Another method for large dirt piles is to build a ramp approach to the pile.

It is important to keep the bucket level when approaching a bank or pile. This will help prevent gouging the work area.

F-3778-12-04 Operation Section 4-4

Page 27

OPERATION

PEELING AND SCRAPING

Use a slight bucket angle, travel forward and hold lift control forward to start the cut. Make a short 5 to 8 foot angle cut and break out cleanly.

With bucket level, start a cut at notch approximately 2 inches deep. Hold depth by feathering bucket control to adjust cutting lip up or down. When front tires enter the notch, adjust lift cylinders to maintain proper depth.

Do not roll bucket over and attempt to backgrade. This type of use can cause severe overloading of bucket cylinders when fully extended, possibly causing bucket cylinder rods to become bent.

BACKFILLING

Approach pile with a level bucket.

Make additional passes until desired depth is reached. During each pass, use only bucket control while working depth. This will allow you to concentrate on controlling bucket angle to maintain a precise cut.

LOADING LOW TRUCKS OR SPREADERS FROM A PILE

For faster loading, minimize angle of turn and length of run between pile and spreader.

Backgrade occasionally with a loaded bucket to keep working surface free of ruts and holes. Also, hold lift control forward so full weight of bucket is scraping ground.

OPERATION

Poor methods actually move no more dirt and make it more difficult to hold a level grade.

Do not use bucket in dumped position for bulldozing. This method, shown above, will impose severe shock loadings on dump linkage, bucket cylinder and tractor.

F-3778-12-04 Operation Section 4-5

Page 28

OPERATION

Leave dirt in bucket. Dumping on each pass wastes time.

Operate tractor at right angles to ditch. Take as big a bite as tractor can handle without lugging down.

OPERATION

Leave dirt which drifts over side of bucket for final cleanup.

Pile dirt on high side for easier backfilling on a slope.

HANDLING LARGE HEAVY OBJECTS

DANGER

1. Using front end loaders for handling large heavy objects such as large round or rectangular bales, logs and oil drums is not recommended.

2. Handling large heavy objects can be extremely dangerous due to:

•

Danger of tractor rolling over.

•

Danger of up-ending tractor.

•

Danger of object rolling or sliding down loader arms onto operator.

3. If you must perform above work, protect yourself by:

•

Never lifting load higher than necessary to clear ground when moving.

•

Ballasting tractor rear to compensate for load.

•

Never lifting large objects with equipment that does not have an anti-rollback device.

•

Operating a loader on a hillside is

Gradually open grapple fork tines, allowing material to drop into tub grinder. For round bales it may be necessary to gradually set bale into tub grinder to avoid shock loading tub grinder due to bale weight and to avoid sudden load on grinder mechanism.

Even on level ground, transport bucket and load as low as possible to avoid tipping in case a wheel drops in a rut and to avoid power lines.

OPERATION

WARNING:

OPERATION AND NOMENCLATURE OF MSL (Mechanical Self Leveling) LOADER

MSL maintains the attitude of loader bucket or attachment relative to ground as set by the operator using the tilt cylinders. Constant attitude is maintained when lift cylinders raise or lower boom, as long as no tilt adjustment is made.

MSL consists of linkages connected to loader uprights and extending forward to triangular pivot plates. Equal displacement tilt cylinder base ends are attached to the pivot plates and rod ends are attached to another linkage commonly referred to as a four-bar linkage. The four-bar linkage, which allows increased dump and rollback rotation connects to bucket or attachment.

Hydraulic relief for tilt cylinders is required when raising the boom with attachment fully dumped. The attachment contacts dump stops on underside of front ends of boom. While raising boom, MSL system pushes attachment tighter against dump stops and tilt cylinder base end pressure increases. A hydraulic relief valve cartridge allows the pressurized oil to transfer to rod end of tilt cylinder, eliminating excessive loads on MSL system. Hydraulic relief is not necessary when lowering boom.

IMPORTANT:

tubes and hoses are correctly plumbed for proper operation of MSL relief valve. Refer to diagram below. Pressure setting for relief valve is set at 210 bar (3,045 psi) and MUST is stamped with required 210 bar setting.

4. Ensure that each employee tightens the Seatbelt sufficiently to confine the employee to the protected area provided by the ROPS.

REQUIRED OF THE OPERATOR

1. Securely fasten seatbelt if the tractor has a ROPS.

2. Where possible, avoid operating the tractor near ditches, embankments, and holes.

3. Reduce speed when turning, crossing slopes, and on rough, slick, or muddy surfaces.

4. Stay off slopes too steep for safe operation.

5. Watch where you are going trees.

6. Do not permit others to ride.

7. Operate the tractor smoothly
