SAFE OPERATION

Most loader equipment accidents can be avoided by following simple safety precautions.These safety precautions, iffollowed at all times, will help you operate your loader safely.

1. BEFORE OPERATING THE LOADER

1. Read and understand all instructions and precautionsfound in both the tractor and the loader operator'smanuals before using the loader.Lack of knowledge can lead to accidents.

2. It is the owner's responsibility to ensure that anyonewho will operate the loader reads this manual first andbecomes familiar with the safe operation of the loader.

3. For your safety, a ROPS with a seat belt is stronglyrecommended by KUBOTA in almost all applications.If your tractor has a foldable ROPS, fold it down onlywhen absolutely necessary and raise it up and lock itagain as soon as possible. Do not wear the seat beltwhen a foldable ROPS is down or a fixed ROPS is

removed. Ifyou have any questions, consult your localKUBOTA dealer.

Always use the seat belt when the tractor is equippedwith a ROPS. Never use the seat belt when the tractor

is not equipped with a ROPS.4. Visually check for hydraulic leaks and broken, missing,

or malfunctioning parts.Make necessary repairs before operating.

5. Replace damaged or illegible safety labels. Seefollowing pages for required labels.

6. When the front loader is mounted on the tractor, enterand exit the operator's seat only from left side of thetractor.

7. Engage the loader control valve lock to preventaccidental actuation when the implement is not in useor during transport. Do not utilize the valve lock formachine maintenance or repair.

8. Assemble, remove and reinstall the loader only asdirected in this manual. Failure to do this could result

in serious personal injury or death.9. Follow the precautions below when attaching

attachments.

• Make sure both handles (LH, RH) contact the earplates at the points (A) and are all the way down.

• Make sure both lock pins (LH, RH) protrude throughthe pin slots.

• Kubota recommends the use of Kubota attachments

on Kubota loaders. Non-Kubota attachments, if used,must comply with ISO 24410, first edition 2005-04-15.

• Use of a non-Kubota attachment that does not complywith ISO 24410 or the improper positioning ofhandle(s) or non-protrusion of pin(s) may result indetachment of the attachment or deformation, causingloss of performance, personal injury or death.

1.

6.

7.

8.

Operate the loader only when properly seated at thecontrols. Do not operate from the ground.Move and turn the tractor at low speeds.Never allow anyone to get under the loader bucket orreach through the boom when the bucket is raised.Keep children, others and livestock away whenoperating loader and tractor.Do not walk or work under a raised loader bucket or

attachment unless it is securely blocked and held inposition.For tractor stability and operator safety, rear ballastmust be added to the 3-point hitch and to the rearwheels when using loader.To increase stability adjust the rear wheels to thewidest setting that is suitable for your application.Exercise extra caution when operating the loader witha raised bucket or attachment.

9. Do not lift or carry any person on the loader, in thebucket, or other attachment.

10.Avoid loose fill, rocks and holes. They can bedangerous for loader operation or movement.

11 .Avoid overhead wires and obstacles when the loader

is raised. Contacting electric lines can causeelectrocution.

12. Gradually stop the loader boom when lowering orlifting.

13. Use caution when handling loose or shiftable loads.14. Using loaders for handling large, heavy, or shiftable

objects is not recommended without proper handlingattachments.

15. Handling large heavy objects can be extremelydangerous due to:• Danger of rolling the tractor over.• Danger of upending the tractor.• Danger of the object rolling or sliding down the

loader boom onto the operator.16. Ifyou must perform this sort of work (item 15), protect

yourself by:• Never lift the load higher than necessary to clear

the ground.• Add rear ballast to the tractor to compensate for the

load or use rear implement.• Never lift large objects with equipment that may

permit them to roll back onto the operator.• Move slowly and carefully, avoiding rough terrain.

17. Never lift or pull a load from any point on the loaderwith a chain, rope, or cable. Doing so could cause arollover or serious damage to the loader.

18. Be extra careful when operating the tractor on a slope,always operate up and down, never across the slope.Do not operate on steep slopes or unstable surfaces.

19. When operating another implement on a hillside, besure to remove the loader to reduce the risk of rollover.

20. Carry loader boom at a low position during transport.(You should be able to see over the bucket.)

21 .Allow for the loader length when making turns.

3. AFTER OPERATING THE LOADER

1. When loader work is complete and parking or storing,choose flat and hard ground. Lower the loader boomto the ground, stop the engine, set the brakes andremove the key before leaving the tractor seat.

2. Make sure the detached loader is on stands and on a

hard, level surface.3. Before disconnecting hydraulic lines, relieve all

hydraulic pressure by moving the controls.4. Do not remove the loader from the tractor without an

approved bucket attached.

4. SERVICING THE LOADER

1. Always wear safety goggles when servicing orrepairing the machine.

2. Do not modify the loader. Unauthorized modificationmay affect the function of the loader, which may resultin personal injury.

3. Do not use the loader as a work platform or a jack tosupport the tractor for servicing or maintenance.Securely support the tractor or any machine elementswith stands or suitable blocking before workingunderneath.

For your safety, do not work under any hydraulicallysupported devices. They can settle or suddenly leakdown or be accidentally lowered.

4. Escaping hydraulic oil under pressure can havesufficient force to penetrate the skin, causing seriouspersonal injury. Do not use hands to search forsuspected leaks. If injured by escaping fluid, obtainmedical treatment immediately.

5. Do not tamper with the relief valve setting. The reliefvalve is pre-set at the factory. Changing the settingcan cause overloading of the loader and tractor whichmay result in serious personal injury.

6. When servicing or replacing pins in cylinder ends,bucket, etc., always use a brass drift and hammer.Failure to do so could result in injury from flying metalfragments.

TEST OPERATION

A WARNINGTo avoid serious personal injury:

Keep engine speed at low idle during the testoperation.Escaping hydraulic fluid under pressure canhave sufficient force to penetrate skin, causingserious personal Injury.Before disconnecting lines, be sure to relieveall pressure by moving the controls.Before applying pressure to the system, besure ail connections are tight and that lines,tubes and hoses are not damaged.Fluid escaping from a very small hole can bealmost Invisible. Use a piece of cardboard orwood, rather than your hands to search forsuspected leaks.If injured by escaping fluid, see a doctor atonce. Serious infection or allergic reaction willdevelop If proper medical treatment is notadministered immediately.

PRE-OPERATION CHECK

1AIABACAP011B

NOTE:• When the lever is at each comer position marked by

asterisk (*) or lower left, boom and bucket cylinderswork at the same time. However, the lower left position(Raise & Roll back) is not recommended for scoopingbecause of insufficient lift force.

To begin a test operation, slightly move the control leverfrom the "N" position. Slowly raise the loader boom justenough for the bucket to clear the ground when fullydumped. Slowly work through the dump and roll backcycles.

IMPORTANT:• If the boom or bucket does not work in the directions

indicated on the label, lower the bucket to the ground,stop the engine, and relieve all hydraulic pressure.Recheck and correct all hydraulic connections and oillevel.

•4 Position bucket control valve typeThis control valve has two stage dump positions. The firstdump position by moving the lever to the right featuresgreater speed for dumping.The second dump position (to further right) is the"Regular" dump position. It has good power and controlfor dumping precisely. This position should be used whenoperating another implement with this control valve.These two positions are separated by a "Feel" position foryour convenience.

REMOVING AIR FROM THE HYDRAULICSYSTEMRepeat raising and lowering the boom and bucketoperations until all the air is removed from the system andthe system responds properly.

IMPORTANT:• Do not move the control lever into the float position

when the bucket is off the ground.

NOTE:• Move the lever to the "FLOAT' position, and it will be

held there by the detent mechanism. To use the valveas a floating valve with detents, connect the hydraulichoses to ports [A] and [B].

• When taking off hydraulic power from port [D], the flowrate can be adjusted in 2 stages with the lever.The flow rate is high at position (R1) and low atposition (R2). Move the lever to position (R1) or (R2)depending on the attachment in use.


OPERATING THE LOADER

The loader should be operated with the tractor enginespeed depending on the application and the operator'slevel of experience. Excessive speeds are dangerous,and may cause bucket spillage and unnecessary strain onthe tractor and loader.

When operating in temperatures below -1 "C(30T), runthe tractor engine below 1200 rpm until the oiltemperature exceeds -1 "C(30 °F).The following text and illustrations offer suggested loaderand tractor operating techniques.

A WARNINGTo reduce the possibility of roll over:• It is not recommended that the loader be

attached when operating another implement ona hillside.

IIVIPORTANT:• Before operating the loader in rough terrain, remove

the mower to avoid damage to the mower.

FILLING THE BUCKETApproach and enter the pile with a level bucket.

1AIABACAP012A

Ease control lever toward you and then left to rollback andlift the bucket.

I

1AGAECDAP009H

The rollback and lifting of the bucket will increaseefficiency because a level bucket throughout the liftingcycle resists bucket lift and increases breakaway effort.

INCORRECT CORRECT

1AIABACAP014A

NOTE:• Do not be concerned if the bucket is not completely

filled during each pass. Maximum productivity isdetermined by the amount of material loaded in agiven period of time. Time is lost if two or moreattempts are made to fill the bucket on each pass.

LIFTING THE LOADWhen lifting the load, keep the bucket positioned to avoidspillage.

1AIABACAP015A

WARNINGTo avoid serious personal injury:• Do not attempt to lift bucket loads in excess of

the loader capacity.• Before raising the bucket to full height, make

sure the tractor is on level ground. If not, it maytip over, even if the tractor is not moving.

12 OPERATING THE LOADER

CARRYING THE LOADPosition the bucket just below the level of the tractor hoodfor maximum stability and visibility, whether the bucket isloaded or empty.

1AIABACAP016A

Use extreme care when operating the loader on a slope.Keep the bucket as lowas possible. This keeps the bucketand tractor center of gravity low and willprovide maximumtractor stability.

A WARNINGTo avoid serious personal injury:• Be extra careful when working on inclines.• When operating on a slope, always operate up

and down the slope, never across the slope.

INCORRECT1AIABACAP017A

CORRECT

When transporting a load, keep the bucket as low as

possible to avoid tipping, in case a wheel drops in a rut.

INCORRECT CORRECT

1AIABACAP018A

DUMPING THE BUCKETLift the bucket just high enough to clear the side of thevehicle. Move the tractor in as close to the side of the

vehicle as possible, then dump the bucket.

1AIABACAP019A

LOWERING THE BUCKETAfter the bucket is dumped, back away from the vehiclewhile lowering and rolling back the bucket.

OPERATING WITH FLOAT CONTROLDuring operation on hard surfaces, keep the bucket leveland put the lift control in the float position to permit thebucket to float on the working surfaces.If hydraulic down pressure is exerted on the bucket it willwear faster than normal.

The float position will also avoid mixingof surface materialwith stockpile material. The float position will reduce thechance of surface gouging while removing snow or othermaterial, or when working with a blade.

LOADING FROM A BANKChoose a forward gear that provides a safe ground speedand power for loading.

1AIABACAP023A ^

To avoid serious personal injury:• Be extra carefui wlien working on inciines.• When operating on a slope, always operate up

and down the slope, never across the slope.

NOTE:• Loader lift and break-away capacity diminish as

loading height is increased.

Side cutting is a good technique for cutting down a bigpile. Wheel width should not exceed the bucket width forthis procedure.

1AIABACAP024A

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

cut over the top.

1AIABACAP025A


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

1AIABACAP026A

It is important to keep the bucket level when approachinga bank or pile. This will help avoid gouging the work area.

1AIABACAP027A

PEELING AND SCRAPINGUse a slight bucket down angle, travel fonward, and holdthe lift control forward to start the cut. Make a short cut

and break-out cleanly.

1AIABACAP028A

With the bucket level, start a cut at the notch

approximately 2 in. deep. Hold the depth by feathering thebucket control to adjust the cutting edge up or down.When the front tires enter the notch, adjust the boomcylinder to maintain proper depth.

1AIABACAP029A

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

1AIABACAP030A


LOADING LOW TRUCKS ORSPREADERSFROM A PILEFor faster loading, minimize the angle of turn and lengthof run between pile and spreader.

1AIABACAP031A

Backgrade occasionally with a loaded bucket to keep thework surface free of ruts and holes. Also, hold the lift

control forward so the full weight of the bucket is scrapingthe ground. Use the heel of the bucket

1AIABACAP032A

BACKFILLINGApproach the pile with the bucket flat.

CORRECT

1AIABACAP033A

Poor operating methods will move less dirt and make itmore difficult to hold a level grade.

INCORRECT

1AIABACAP034A

IMPORTANT:• Do not use the bucket in the dumped position for

bulldozing. As shown above, this method will imposesevere shock loads on the dump-linkage, the bucketcylinders, and the tractor.

Leave dirt in the bucket because dumping on each passwastes time.

•iOperate at right angles to the ditch. Taking as big a biteas the tractor can handle.
