SAFETY RULES

ATTENTION! BECOME ALERT! YOUR SAFETY IS INVOLVED!

Safety is a primary concern in the design and manufacture of our products. Unfortunately, our efforts to provide safe equipment can be wiped out by an operator’s single careless act.

In addition to the design and configuration of equipment, hazard control and accident prevention are dependent upon the awareness, concern, judgement, and proper training of personnel involved in the operation, transport, maintenance, and storage of equipment.

It has been said, “The best safety device is an informed, careful operator.” We ask you to be that kind of operator.

INSTALLATION

Hydraulics must be connected as instructed in this manual. Do not substitute parts, modify, or connect in any other way.

After connecting hoses, check that all control lever positions function as instructed in the Operator's Manual. Do not put into service until control lever and equipment movements are correct.

TRAINING

Safety instructions are important! Read all attachment and power unit manuals; follow all safety rules and safety decal information. (Replacement manuals and safety decals are available from your dealer. To locate your nearest dealer, check the Dealer Locator at www.WoodsEquipment.com, or in the United States and Canada call 1-800-319- 6637.) Failure to follow instructions or safety rules can result in serious injury or death.

If you do not understand any part of this manual and need assistance, see your dealer.

Know your controls and how to stop engine and attachment quickly in an emergency.

Operators must be instructed in and be capable of the safe operation of the equipment, its attachments, and all controls. Do not allow anyone to operate this equipment without proper instructions.

Keep hands and body away from pressurized lines. Use paper or cardboard, not hands or other body parts to check for leaks. Wear safety goggles. Hydraulic fluid under pressure can easily penetrate skin and will cause serious injury or death.

Make sure that all operating and service personnel know that if hydraulic fluid penetrates skin, it must be surgically removed as soon as possible by a doctor familiar with this form of injury or gan-

grene, serious injury, or death will result. CONTACT A PHYSICIAN IMMEDIATELY IF FLUID ENTERS SKIN OR EYES. DO NOT DELAY.

Never allow children or untrained persons to operate equipment.

PREPARATION

Check that all hardware is properly installed. Always tighten to torque chart specifications unless instructed otherwise in this manual.

Air in hydraulic systems can cause erratic operation and allows loads or equipment components to drop unexpectedly. When connecting equipment or hoses or performing any hydraulic maintenance, purge any air in hydraulic system by operating all hydraulic functions several times. Do this before putting into service or allowing anyone to approach the equipment.

After connecting hoses, check that all control lever positions function as instructed in the Operator's Manual. Do not put into service until control lever and equipment movements are correct.

Protective hose sleeves must cover all hydraulic hoses within 20 inches of the operator and be secured onto metal hose fittings. Replace hoses or sleeves if damaged or if protective sleeve cannot be properly positioned or secured.

Make sure all hydraulic hoses, fittings, and valves are in good condition and not leaking before starting power unit or using equipment. Check and route hoses carefully to prevent damage. Hoses must not be twisted, bent sharply, kinked, frayed, pinched, or come into contact with any moving parts. Operate moveable components through full operational range to check clearances. Replace any damaged hoses immediately.

Always wear relatively tight and belted clothing to avoid getting caught in moving parts. Wear sturdy, rough-soled work shoes and protective equipment for eyes, hair, hands, hearing, and head; and respirator or filter mask where appropriate.

Make sure spring-activated locking pin or collar slides freely and is seated firmly in tractor PTO spline groove.

Make sure attachment is properly secured, adjusted, and in good operating condition.

Power unit must be equipped with ROPS or ROPS cab and seat belt. Keep seat belt securely fastened. Falling off power unit can result in death from being run over or crushed. Keep foldable ROPS system in “locked up” position at all times.

SAFETY RULES

ATTENTION! BECOME ALERT! YOUR SAFETY IS INVOLVED!

Only mount this backhoe on 50 hp or greater, Category 2 or 3 tractors with 2000 lb. lift capacity and with OEM high-strength top link pin of at least 1” diameter or approved top link brackets and pins. Brackets and pins are available from your WOODS dealer for some tractors not originally equipped with 1” diameter pins.

Refer to “Mounting Guide” (available from your dealer) for some tractors not originally equipped with 1” diameter pins.

Never put backhoe into service unless backhoe manufacturer's 3-point hitch Saf-T-Lok® limiter or sub-frame has been installed and adjusted.

Make sure shields and guards are properly installed and in good condition. Replace if damaged.

A minimum 25% of tractor and equipment weight must be on the tractor front wheels when attachments are in transport position. Without this weight, tractor could tip over, causing personal injury or death. The weight may be attained with a loader, front wheel weights, ballast in tires, or front tractor weights. Weigh the tractor and equipment. Do not estimate.

Clean all dirt, trash, and grease from operator's platform and steps.

Do not use a 3-point quick hitch. The quick hitch will result in improper PTO driveline geometry.

To avoid possible hitch failure, read and follow the Saf-T-Lok Limiter Installation Instructions in the Assembly section before mounting backhoe to tractor 3-point hitch.

Remove seat and upper support assembly before installing or removing backhoe from tractor. Failure to comply may result in equipment failure and/or personal injury.

Connect PTO driveline directly to power unit PTO shaft. Never use adapter sleeves or adapter shafts. Adapters can cause driveline failures due to incorrect spline or incorrect operating length and can result in personal injury or death.

Make sure safety chain is properly connected and secured to tractor.

Do not operate backhoe unless there is adequate operator clearance as shown on safety decal. (Refer to Danger decal in Safety Decal section.)

Always use the special heavy-duty top link (provided with backhoe) and the OEM high-strength top link pin (provided with tractor) to mount top link to tractor. Use a 1” x 5” grade 5 bolt to mount top link to backhoe.

Be sure that backhoe is properly mounted, adjusted, and in good operating condition.

Place and keep 3-point lift quadrant lever in lowered position at all times.

OPERATION

The operator is responsible for the safe operation of the backhoe. The operator must be properly trained. Operators should be familiar with the backhoe, the tractor, and all safety practices before starting operation. Read the safety rules and safety decals on page 7 to page 11.

Hydraulic pressure for backhoe operation is supplied by a tractor PTO driven pump. Two pumps are available to operate at either 540 or 1000 rpm. Make sure you have the proper pump for your tractor rpm. Never exceed the rated pump rpm. Operating the pump in excess of the rated rpm will cause overheating and damage to the equipment.

Never put backhoe into service unless backhoe manufacturer's 3-point hitch Saf-T-Lok® limiter or sub-frame has been installed and adjusted.

Do not operate backhoe unless there is adequate operator clearance as shown on safety decal. (Refer to Danger decal in Safety Decal section.)

Make sure all hydraulic hoses, fittings, and valves are in good condition and not leaking before starting power unit or using equipment. Check and route hoses carefully to prevent damage. Hoses must not be twisted, bent sharply, kinked, frayed, pinched, or come into contact with any moving parts. Operate moveable components through full operational range to check clearances. Replace any damaged hoses immediately.

Make sure that all operating and service personnel know that if hydraulic fluid penetrates skin, it must be surgically removed as soon as possible by a doctor familiar with this form of injury or gangrene, serious injury, or death will result. CONTACT A PHYSICIAN IMMEDIATELY IF FLUID ENTERS SKIN OR EYES. DO NOT DELAY.

Keep hands and body away from pressurized lines. Use paper or cardboard, not hands or other body parts to check for leaks. Wear safety goggles. Hydraulic fluid under pressure can easily penetrate skin and will cause serious injury or death.

Consult local utilities before working. Know location of all underground cables, pipelines, overhead wires, and other hazards in working area and avoid contact.

A minimum 20% of tractor and equipment weight must be on tractor front wheels with back-

hoe in transport position. Without this weight, tractor could tip over, causing personal injury or death. The weight may be attained with a loader, front wheel weights, ballast in tires, or front tractor weights. When attaining the minimum 20% weight on the front wheels, you must not exceed the Roll Over Protection Structure (ROPS) weight certification. Weigh the tractor and equipment. Do not estimate.

Start and Stop Operation

Operate tractor PTO at 540 RPM. Do not exceed.

Power for operating backhoe hydraulic system is supplied by a hydraulic pump driven by the tractor PTO. Instructions for engaging and disengaging the PTO are in your tractor manual. Learn how to disengage PTO quickly should an emergency occur.

Never exceed the rated pump rpm. Operating the pump in excess of the rated rpm will cause overheating and equipment damage.

GENERAL OPERATION

Place and keep 3-point lift quadrant lever in lowered position at all times.

If tractor is equipped with draft sensing control, set control to “HEAVY” (minimum sensitivity) position.

Do not use backhoe for craning; it is primarily designed for digging. Mechanical failures such as hose rupture will cause a load to drop suddenly.

Never allow children or untrained persons to operate equipment.

CAUTION

When operating controls, always sit in backhoe seat.

Mechanical failures such as a hose rupture will cause a load to drop. Lifting a heavy load with the dipper, then operating the boom, could cause boom to drop. In either case, if anyone is in the operating area (maximum reach of bucket) as shown in Figure 3, serious injury or death could occur.

Do not dig with backhoe unless stabilizers are down and on a firm surface. Stay clear of steep areas or excavation banks that are soft or could give way.

Figure 3. Backhoe Swing Area.

POSITION THE MACHINE

Before operating in an unfamiliar area, walk around the full length of the proposed site and check for hidden holes, drop-off or obstacles that could cause an accident.

Lower stabilizers until they carry the weight of the backhoe. If tractor is equipped with a front loader, place the bucket flat on the ground. Lower loader lift arms until weight is removed from front tractor tires.

Level the machine using stabilizers and front loader before starting to dig.

Stability is very important when operating backhoe in the extreme swing positions as this causes weight transfer.

CONTROL HANDLE OPERATION

Refer to Figure 4.

Assume your position in the operator's seat.

When engaging optional PTO-mounted pump, engine rpm should always be low. Once engaged, engine rpm may be increased to desirable operation speed.

When becoming familiar with backhoe controls, start with a lower rpm.

Before operating, perform a functional test by placing control handles in their various positions and making certain correct operation occurs, matching decals on operator's console. Pay specific attention to the float position of boom. Do not operate backhoe if functions differ from decal; serious injury or death could occur.

It is not difficult to become a successful operator. Control lever operating decals (shown in Figure 4) are next to the operating control levers. Study these decals; they will assist you in becoming familiar with the controls.

Pushing handle 1 forward will lower left stabilizer; pulling back raises it.

Pushing handle 2 forward will lower right stabilizer; pulling back raises it.

Pulling left control back (toward A) raises boom; pushing it forward (toward C) lowers it. Full forward (toward C) is the float position.

Moving left handle left (toward B) swings boom left; moving it right (toward D) swings boom right.

Pulling right control back (toward E) moves dipper down and toward operator; pushing it forward (toward G) moves it up and away from operator.

Moving right handle left (toward F) curls bucket toward operator; moving it right (toward H) extends bucket out away from operator.

Operate the control levers, swinging the boom several times to practice control. Do not operate the swing more than 45° each way the first few times. Gradually increase arc.

Figure 4. Operator’s Controls (Typical View)

After becoming familiar with the backhoe operation, practice coordinated use of the controls in a safe open area at reduced engine speed. Gradually increase engine speed as the technique is mastered.

Operate backhoe gently and smoothly. Avoid swinging boom into mainframe. Sudden stopping or jerking could result in serious damage to tractor and backhoe.

Strive to develop a smooth digging cycle. Avoid abrupt or jerky movements. This is accomplished by operating two or more controls at the same time and not allowing the cylinders to reach the limit of travel.

Should you become confused during operation, simply let go of the controls. The valve control handles will automatically return to neutral.

START EXCAVATION

Consult local utilities before working. Know location of all underground cables, pipelines, overhead wires, and other hazards in working area and avoid contact.

DB3391

Figure 5. Starting Position

To start the excavation, position backhoe as shown in Figure 5 for maximum breakout force.

Actuate the dipper cylinder to start digging. Approximately halfway through digging cycle, start bucket curl while continuing crowding dipper in. Should bucket stall, raise boom slightly.

Do not use down pressure on the boom when starting to dig, as this will lift the machine and move it out of alignment with the work.

FILL BUCKET

Control bucket attitude throughout digging cycle to keep teeth parallel to bottom of excavation. This will provide best penetration angle and minimize dragging and scraping bucket through the ground.

Penetration depth is determined by soil condition and type.

Only use dipper and bucket during the digging cycle. As the dipper moves the bucket through the soil, curl bucket to maintain proper bucket position.

At the end of the pass, or when bucket is full, curl bucket completely, lift bucket from excavation and swing boom to dump site.

To obtain a cleaner trench and avoid material buildup directly in front of backhoe, extend dipper and curl bucket completely while starting to lift it out of the excavation. This will allow excess material to fall back into the excavation.

DUMP AND RETURN CYCLE

Keep the swing-dump-return cycle as brief as possible. Keep dipper moving outward and start boom swing as soon as the bucket clears the excavation. Continue extending dipper and, as you approach the spoil pile, start to dump bucket.

When bucket is empty, dipper and bucket are in position to resume digging upon return to the excavation.

TRENCHING AND EXCAVATING

Trenching is the most basic backhoe digging operation. Other operations are variations of this basic function.

To maintain a level trench bottom, set bucket at proper approach angle and while crowding dipper-stick in, continually move bucket curl lever to maintain correct cutting angle. At the same time, place boom control in the full forward (float) position and keep the bucket in the same plane.

When handle is placed in the float position, pressure on both sides of boom cylinder is released.

Digging near center of swing so material may be dumped on either side will produce good results. Never dig near stabilizers.

Continue the trench by moving machine along trench centerline away from existing excavation. Move machine approximately one-half the effective backhoe reach. Moving too far will require excessive down pressure for digging and hand clean-up of trench bottom.

SIDE SLOPE TRENCHING / EXCAVATING

Be careful when swinging loaded bucket on hillside. Always dump spoil on uphill side of backhoe to minimize rollover possibility.

When operating on a side slope, the backhoe must be positioned using one of these two methods as shown in Figure 8 or Figure 9.

When operating on a side slope, always place the trench spoil on the uphill side.

DB3388

Level the machine on side slope using the stabilizers.

Figure 8. Level with Stabilizers

When leveling with a cutout, cut a level pad for the uphill side of the machine and place spoil on the downhill side as shown in Figure 9.

TRANSPORTING

Always engage swing and boom transport locks and attach Slow Moving Vehicle (SMV) sign before transporting backhoe.

Power unit must be equipped with ROPS or ROPS cab and seat belt. Keep seat belt securely fastened. Falling off power unit can result in death

from being run over or crushed. Keep foldable ROPS system in “locked up” position at all times.

Never leave equipment unattended with engine running or with bucket in raised position. Always engage swing and boom transport locks, relieve system pressure by operating controls, and remove ignition key before leaving equipment.

Transport and Swing Lock Installation

IMPORTANT

Before operating backhoe, disengage transport lock bar and store swing lock pin. Push transport lock bar down fully to prevent damage.

Engage transport lock by fully retracting boom and dipper. Position transport latch plate (1), located on right side of swing frame, over transport lock pin (2). Secure with safety pin (4). See Figure 10.

Center boom from side to side and install swing lock pin (6) through plates (8) and swing frame (7). Place swing lock pin (6) in storage hole (9) when not in use.

Always raise stabilizers before transporting backhoe.

REMOVING AND STORING BACKHOE

The only time the backhoe may be operated from a position other than the operator seat is during backhoe attachment and removal. Operator must:

Read Mounting Kit Manual instructions on attaching and removing backhoe and use extreme care.

Always stand between rear tire and backhoe stabilizer arms or along side of tractor to avoid being trapped should the boom swing control be accidentally activated.

Keep all persons away from operator control area while performing adjustments, service, or maintenance.

Figure 10. Transport and Swing Lock Installed

3-Point Hitch Saf-T-Lok®

Center the boom, install swing lock pin, then extend boom and dipperstick. Rest bucket on the ground. Lower stabilizers to take backhoe weight off of tractor.

Remove pin that attaches top link to tractor. Remove lower 3-point arms from backhoe. Place blocks under mainframe and raise stabilizers to lower backhoe mainframe onto blocks. Block backhoe as necessary to make it stable.

Disconnect hydraulic pump from tractor and store off ground. Slowly drive tractor away from backhoe.

CLEANING

After Each Use

Remove large debris such as clumps of dirt, grass, crop residue, etc. from machine.

16 Operation

51861 (Rev. 6/16/2006)

 

 

Inspect machine and replace worn or damaged parts.

Replace any safety decals that are missing or not readable.

Periodically or Before Extended Storage

Clean large debris such as clumps of dirt, grass, crop residue, etc. from machine.

Remove the remainder using a low-pressure water spray.

1.Be careful when spraying near scratched or torn safety decals or near edges of decals as water spray can peel decal off surface.

2.Be careful when spraying near chipped or scratched paint as water spray can lift paint.

3.If a pressure washer is used, follow the advice of the pressure washer manufacturer.

Inspect machine and replace worn or damaged parts.

Sand down scratches and the edges of areas of missing paint and coat with Woods spray paint of matching color (purchase from your Woods dealer).

Replace any safety decals that are missing or not readable (supplied free by your Woods dealer). See Safety Decals section for location drawing.

PRE-OPERATION CHECK LIST

(OWNER'S RESPONSIBILITY)

The operator should perform the following check list before operating the backhoe.

___ Check that backhoe is properly and securely attached to tractor.

___ Make sure all hydraulic connections are tight and all hydraulic lines and hoses are in good condition before engaging tractor PTO.

___ Check that there are no leaks in the hydraulic system. Before operating, all hydraulic hoses must be routed properly and not be twisted, bent sharply, kinked, pulled tight or frayed.

___ During inspection, check that all nuts and bolts are secure and clevis pins are properly cotter pinned.

___ Be sure special heavy-duty top link, provided with backhoe, is installed.

___ Make sure only original equipment highstrength top link pin, provided with tractor, is used to attach top link to tractor.

___ Use a 1" x 5" grade 5 bolt to mount top link to backhoe.

___ Make sure tractor lower lift arm stabilizers (blocks or chains) are positioned to prevent lift arms and backhoe from swaying.

___ Place all backhoe controls in neutral position before starting tractor engine.

___ Check hydraulic reservoir level.

___ Remove transport lock bar from the boom. Push transport lock bar down fully to prevent damage.

___ Place and keep 3-point lift quadrant lever in lower position at all times.

___ Set draft sensing control to “heavy” (minimum sensitivity) position. The minimum sensitivity setting indicates to the tractor lift system that a heavy load is being applied to the lift arms and will minimize the potential for the lift arms to raise. Raising lower lift arms would apply

greater loads to the Saf-T-Lok® diagonal braces, which is not desirable.

OWNER SERVICE

The information in this section is written for operators who possess basic mechanical skills. If you need help, your dealer has trained service technicians available. For your protection, read and follow the safety information in this manual.

Keep hands and body away from pressurized lines. Use paper or cardboard, not hands or other body parts to check for leaks. Wear safety goggles. Hydraulic fluid under pressure can easily penetrate skin and will cause serious injury or death.

Make sure that all operating and service personnel know that if hydraulic fluid penetrates skin, it must be surgically removed as soon as possible by a doctor familiar with this form of injury or gangrene, serious injury, or death will result. CONTACT A PHYSICIAN IMMEDIATELY IF FLUID ENTERS SKIN OR EYES. DO NOT DELAY.

Before working on backhoe, extend boom and dipperstick and place bucket on ground. Make sure that all system pressure has been relieved by operating controls before maintenance, service, or disconnecting any hydraulic lines.

CAUTION

Always wear relatively tight and belted clothing to avoid getting caught in moving parts. Wear sturdy, rough-soled work shoes and protective equipment for eyes, hair, hands, hearing, and head; and respirator or filter mask where appropriate.

OPTIONAL AUXILIARY PUMP AND HYDRAULIC SYSTEM

IMPORTANT

Fill with clean oil. Do not mix oil types or grades.

Daily, check the fluid level in reservoir with filler cap dipstick. Contamination will shorten the life of hydraulic system components. Change oil and filter after first 20 hours of operation and then every 200 hours of operation or annually, whichever occurs first. In extremely dusty or dry conditions, more frequent changes may be necessary. System capacity is approximately 5 to 5-1/2 US gallons.

Engage PTO and run at idle for 5 minutes, then check oil level. Add fluid as necessary.
