PRE-OPERATION

3509 & 3511 BACKHOE

GENERAL INFORMATION

The purpose of this manual is to assist in setting up, operating and maintaining your backhoe. Read it carefully. It furnishes information and instructions that will help you achieve years of dependable performance.

Right and left, when referred to in this manual, are determined from the operator's control position when facing the backhoe.

The illustrations and data used in this manual were current (according to the information available to us) at the time of printing, however, we reserve the right to redesign and change the backhoes as may be necessary without notification.

PREPARING THE TRACTOR

WARNING! Never let anyone operate this tractor and backhoe without first reading the "Safety Precautions" and "Operating Instructions" sections of this manual (see Sections B and G respectively).

Always choose hard, level ground to park the tractor on and set the brake so that the tractor cannot roll.

Before you install a 3-point hitch backhoe on any tractor, there are certain critical points that must be checked. Failure to address these points could result in serious damage to the equipment, and serious injury or even death to the operator.

Do NOT attempt to install the backhoe until you have gone through the following points and made any corrections to the equipment that might be deemed necessary.

PRELIMINARY CLEARANCE CHECK

The first point to consider is if there will be adequate clearance between the backhoe operator and the tractor. Proper clearance is essential for operator safety.

When mounted, there must be a minimum of 24" horizontal clearance (with seat in forward position), and a minimum of 28.43" horizontal clearance (with seat in the extended position). There must also be a minimum vertical clearance of 8" between the operator's head and any portion of the tractor.

Follow the procedure below to check for minimum clearances.

1.

With the tractor 3-point hitch lower links set approximately 8" to 9" off the ground, measure the horizontal distance between the lower link ball joint and any object that comes the closest to interfering with the backhoe seat (such as the ROPS or cab). See Figure #1

7988

HORIZONTAL

CLEARANCE

8" TO 9"

24.00"

28.43"

Figure #1 also shows the minimum horizontal distances between the seat (in the forward and the extended positions), and the lower link mounting point. The distance found in step #1 must be greater than these distances to safely operate the backhoe. Do not mount the backhoe if the distance found in step #1 is less than the 24" minimum. (If the distance found in step #1 is greater than 24" but less than 28.43", make sure the seat is in the forward position.)

2.

To check the vertical clearance, first make sure the lower links are approximately

8" to 9" off the ground. Measure the vertical distance between the lower link ball joint center and any solid object that could interfere with the backhoe operator's head (such as the tractor cab or ROPS). See Figure #2

FIGURE #2

MEASURE FOR VERTICAL CLEARANCE

8" TO 9"

The distance found in step #2 must be at least 78". This distance allows for the height of the backhoe, the height of the seated operator, and the minimum 8" clearance. This figure assumes the operator is 6' tall. You will have to add 1/2" for every inch your operator is over 6' to achieve the correct figure. The distance found in step #2 must be greater than this distance to safely operate the backhoe. Do not mount the backhoe if the distance found in step #2 is less than the 78" minimum.

PRE-OPERATION

3509 & 3511 BACKHOE

NOTE: If your particular situation does not allow for the required backhoe clearance, look for ways to increase the clearance, such as adjusting the backhoe seat in, or moving items on the tractor, etc.

CAUTION!

These clearances are considered minimum to prevent backhoe operator injury during use. The backhoe should not be used in applications where minimum clearances cannot be held. A

HARD HAT SHOULD ALWAYS BE WORN WHEN OPERATING A

BACKHOE.

DRAFT CONTROL CHECK

For tractors with a top link draft control system, make sure the draft control is in its heaviest load position and disconnect the top link draft sensor linkage to cut off the draft control function. It is important to prevent the top link from exerting pressure that may activate the draft control system. Do NOT attempt to lift the backhoe with the 3-point hitch.

IMPORTANT: On tractors with draft control, digging forces of the backhoe could be large enough to trigger the draft control system. Since the mounting system of the backhoe is a solid mount, draft control operation will only cause excess oil pressure and resultant high temperatures. This eventually will lead to hydraulic fluid overheating and to pump failure.

BACKHOE VALVE COMPATIBILITY

The backhoe valve must be compatible with the hydraulic system that will power it. Make sure you are powering the backhoe with an open center hydraulic system. If you are using a closed center hydraulic system or a power beyond set-up, the valve must be converted for this use. Contact your AG ATTACH dealer for valve conversions. If you do not know how your valve is currently set up, check with your tractor dealer. Failure to convert the hydraulic valve will result in seal damage.

HYDRAULIC OIL

Your backhoe has been filled with oil at the factory. The oil in the unit is compatible with most tractor manufacturer's oil. Do not move any control levers on the unit until after the hydraulic connections to the tractor have been made.

BACKHOE OPTIONS

Basic backhoes are shipped complete with bucket. However, several bucket options are available for the backhoe.

MOUNTING INSTRUCTIONS

3-POINT HITCH BACKHOE

GENERAL INFORMATION

The basic 3509 & 3511 backhoe includes a 3-point hitch adapter links and the following hydraulics: check valve, inline filter and two #3708 hoses (.50" X 48" -

8MP-8FJX). Although the adapter links and hydraulic hoses have been installed at the factory, diagrams and parts lists have been included in this section for your convenience. Study the diagrams to make sure that all the necessary parts have been supplied and installed correctly. Install any parts that were not installed at the factory. Refer to the diagrams at the front of this section for proper installation of parts.

ADDITIONAL HYDRAULIC INFORMATION

You will have to adapt to your tractor hydraulic system. You will find that your backhoe will be shipped with the inline filter, check valve, and a pair of hydraulic hoses already installed. Your dealer should provide the rest of the system hook-up to your tractor.

IMPORTANT

Always know your hydraulic system and be sure to observe the following:

Always use hoses of adequate pressure rating for your highest available pressure.

Always use hoses of sufficient size to handle the highest flow available.

Always route the hoses to the attachment in a way that loops, kinks, sharp edges, or snagging possibilities are eliminated.

Always route hoses as far as possible from areas occupied by operator.

Always use the proper kit, if possible, or use identical or equal parts in your assembly.

Hose length supplied is adequate to reach the backhoe before attaching, but not so long as to be able to loop up around the fender or operator after the backhoe is mounted.

All bends and loops etc. do not exceed hose manufacturer's rated radius

specification.

It is important to pick a set of holes that place the backhoe in a vertical position in relationship to the ground with 8" - 9" of ground clearance at the boom pivot pin.

15.

Torque all mounting bolts. Refer to the chart in Section "O" of this manual.

16.

Check hose routing to ensure that they are kept away from the operator during backhoe operation. Do not let them touch the ground.

Secure all hydraulic lines in place for operator safety and to prevent them from being damaged.

17.

Double check clearance between the backhoe operator and any solid portion of the tractor, such as the cab or ROPS. If 8" of head clearance is not available, DO NOT USE THIS BACKHOE ON THIS TRAC-

TOR. Failure to observe these instructions may cause severe personal injury or death.

CAUTION! Do not attempt to modify the mounting in any way. Incorrect mounting or modifying of the backhoe 3-point mounting could allow the backhoe to raise up during use, resulting in injury or death.

IMPORTANT: DO NOT attempt to raise the backhoe with the 3-point hitch.

The backhoe center links along with the hitch lock out arms make the backhoe a solid mount that is immovable. Any attempt to raise the backhoe with the 3-point hitch will cause the hydraulic lift oil to go over relief and eventually damage the hydraulic system due to excessive heat build-up.

OPERATING TECHNIQUES

ATTACHMENT TYPE BACKHOES

GENERAL INFORMATION

When operating the backhoe, smoothness of technique should be strived for at all times. Smoothness will come with experience and practice at feathering the controls. Establish a flowing digging cycle to increase operator efficiency and save unnecessary wear on the machine.

Observe the following points to obtain the best results and to fully utilize the digging force of the backhoe.

WARNING! Operate the backhoe only when seated at the controls. Any other method could result in serious personal injury or death.

Never attempt to drive the tractor when seated at the backhoe controls.

Check the prospective digging area for hidden utility lines before operating the backhoe or when in doubt of their location, contact the local utility companies. When operating the backhoe in an area where utilities are expected to be present, throttle the backhoe down and proceed with caution. If you feel the backhoe bucket made contact with anything out of the ordinary, stop digging at once. Have the obstruction checked by hand. If a utility line has been damaged, contact the affected utility at once.

BEFORE YOU START DIGGING

Before any excavating is started, it is always a good idea to plan out the job first. Various things need to be considered and taken into account prior to the actual digging. The operator should inspect the job site and take notice of any potential hazards in the area. He should have a complete understanding of the tasks he is expected to perform. Figure out what will be done with the spoil

(excavated soil), will it be used to backfill or be trucked out? What are the soil conditions like? Will you have to work around others? Etc.

Once you have become familiar with the job site and understand the job requirements, it is time to set up for the actual digging. Position the backhoe in such a way as to minimize repositioning the unit and to maximize digging efficiency. Consider the placement of spoil and position the backhoe to be able to dig the maximum amount of soil, accurately, while leaving enough room for the spoil removed to be piled in the desired area.

Once the unit is positioned, lower the stabilizers to the ground. The tires should still be supporting most of the vehicle weight with the stabilizers relieving only part of the weight, and mainly acting to give the unit a wider base for increased stability and to keep the unit from moving or bouncing with backhoe use. The front end loader should also be lowered if the unit is so equipped. The vehicle should at no time be supported by the stabilizers and loader with any of its wheels off the ground. Severe damage to the vehicle could result. When operating the unit on a delicate surface

(such as concrete, or stone work) or on sandy, loose, or soft ground place plywood under the stabilizers to help distribute the load over a wider area.

BASIC DIGGING TECHNIQUE

When starting an excavation, make the first cut of each section shallow, being careful to follow the exact layout of the excavation. The reason for the shallow cut is to minimize damage to the sod and to facilitate replacement.

These first cuts are also important because they will act as guides for the remaining cuts, thus getting the first few cuts as accurate as possible will help in keeping all future cuts accurate.

G

When digging with the backhoe, extend the boom, dipper and bucket out, away from the operator. Lower the boom and dipper to start the digging process.

The bucket teeth should be at a 30° to 45° entry angle. As the digging starts, curl the bucket until the cutting edge is level with the horizon. Crowd the bucket in toward the operator working the bucket lever to keep the bucket level. As the bucket moves toward the operator, manipulate the boom lever to keep the cut level. At the end of the digging cycle, crowd the dipper out and completely curl the bucket while lifting it from the excavation. Once you have cleared the excavation, swing the bucket to the spoil pile. Start to dump the bucket before the pile is approached. Once the bucket is empty, swing the unit back to the excavation, positioning the bucket and dipper for the next cut in the process. The whole digging process should be one smooth cycle that is repeated until the excavation is completed.

When the excavation has been dug to within six inches of the finished bottom, clear and touch up the sides of the excavation. Use the flat sides of the bucket to scrape off any high spots. Dislodge any exposed rocks if they seem loose. When finishing walls, finish the far wall by curling the bucket out, crowding the dipper out, and forcing the bucket down. To finish the closest wall, lift the bucket up and curl it in.

Once the sides are cleaned up, finish grading the bottom of the excavation. This is done by making the remaining cuts long and shallow, concentrating on making them level and smooth. Remove any remaining spoil.

Check the excavation bottom for depth and levelness, making any adjusting cuts as needed.

The basic steps just listed at the same regardless of the excavation.

All other digging jobs are simply variations of this basic procedure. Remember to make your cuts in smooth cycles. This will reduce operator fatigue and machine wear while increasing productivity and efficiency.

To check for pipeline leaks, start by digging a bellhole about six feet wide and ten feet long. Then, dig lengthwise along the pipeline to locate the leak. Once the leak is located, position the unit to dig at grade level on both sides of the pipeline. If a section of pipe is to be replaced, strip the soil from both ends of the bellhole. Enlarge the hole enough to allow the workmen adequate working space in the leak area.

DIGGING STRAIGHT WALL SHALLOW BASEMENTS

Begin at one corner, and remove as much material as possible to grade level. Reset the unit forward and continue digging to the grade level.

MISCELLANEOUS - BACKFILLING

To backfill an excavation, lower the extended bucket into the spoil pile. Curl the bucket and lift it clear of the spoil pile. Swing the bucket to the excavation and extend the bucket. Return the bucket to the spoil pile and continue the cycle until the job is completed.

IMPORTANT: Do not backfill by using the swing circuit and dragging the bucket sideways. Doing so could cause damage to the dipper, boom, and swing cylinders or mainframe.

IMPORTANT: Avoid constant jarring or hammering contact between the spoil pile and the loaded bucket as this may cause premature wear to the backhoe pins and bushings.

MISCELLANEOUS - EXCAVATING BY A WALL

To excavate by a wall, where the wall will interfere with the stabilizer placement, move the backhoe in at an angle to the wall. Concentrate on getting the swing pin as close to the wall as possible while leaving enough swing arc left to dump the spoil.

G

MISCELLANEOUS - HARD GROUND OPERATION

When digging in hard ground, it may be necessary to decrease the bucket angle of entry to the point where the back of the bucket almost contacts the ground. It may also be necessary to apply downward pressure with the boom on the bucket.

GENERAL MAINTENANCE

GENERAL INFORMATION

Regular maintenance is the key to long equipment life and safe operation. Maintenance requirements have been reduced to an absolute minimum. However, it is very important that these maintenance functions be performed as described below.

EVERY 8 HOURS OF OPERATION

Visually inspect the unit. Check all connections to 3-point hitch arms to ensure hitch pins are correctly installed and retaining pins are in place.

Grease all swivel points (ram and base end of all cylinders) thoroughly. Excessive wear and even mechanical damage to pins and cylinders can result from inadequate lubrication. Use a multi-purpose grease.

Lubricate all grease fittings with a multi-purpose grease. For grease locations, refer to the lubrication chart in Section H.

EVERY 40 HOURS OF OPERATION

Check hydraulic reservoir fluid level. If oil is low, check all lines, fittings, and control valve for signs of leakage.

IMPORTANT: Hydraulic fluid level should be checked with backhoe in transport position.

WARNING! Escaping hydraulic/diesel fluid under pressure can penetrate the skin causing serious 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 lines.

Tighten all connections before starting engine or pressurizing lines.

If any hydraulic/diesel fluid is injected into the skin, obtain medical attention immediately or gangrene or other serious injury may result.

L

Physically check all pins, bushings, cotter pins, nuts, etc., for signs of wear or loose fit. Tighten as required, replacing where necessary. (Bolts and pins may vibrate loose during operation.) Clean equipment of all dirt, oil, and excess grease. This will assist you in making visual inspection and help avoid overlooking worn or damaged components.

TO BACKHOE

The hydraulic control valve maintenance is normally limited to the replacement of o'ring seals, cleaning and the replacement of valve sections or relief valve cartridges.

The most common cause of premature wear and malfunctioning of the hydraulic system components is the ingress of contaminants and incorrect high pressure inlet and low pressure return connections (cavitation).

Observe a high standard of cleanliness when doing valve maintenance.

CONTROL VALVE CONVERSION

It is imperative that the backhoe valve be of the same type (open center, or closed center) as the tractor hydraulic system it is fitted to. If the backhoe valve is not compatible with the tractor hydraulics, and then is installed and operated directly off of the tractor's hydraulic system, damage to the equipment can result.

The standard backhoe valve contains an open center plug but can be converted to a closed center or power beyond system simply by removing the existing plug in the valve outlet cover and installing the appropriate plug. The plugs come complete with new seals. Plugs should be torqued to 20 ft. lbs.

3509 & 3511 BACKHOES

GENERAL INFORMATION

The information contained on this page may be particularly helpful in determining backhoe and tractor compatibility. It is provided here for your convenience.

TRACTOR SPECIFICATIONS FOR MOUNTING BRADCO BACKHOES

3-Point Category ...........................................................Category II

Tractor Horsepower .....................................................50 - 120 HP

Rated Hitch Lift Capacity........................................... 2400 - 5000#

GVW .....................................................................UP TO 12000#

GPM* ........................................................................ 9 - 12 GPM

* Optimum oil flow is 9-12 GPM. Flows higher than 12 GPM may cause the oil to overheat and the backhoe to respond erratically. Your tractor's GPM can be controlled by the engine RPM. Slow engine RPM if the oil is overheating or the backhoe controls are not functioning smoothly.

NOTICE:

BRADCO MAKES NO CLAIMS OR WARRANTY, IMPLIED OR OTHER-

WISE, as to the compatibility or structural integrity of any tractors 3-point hitch assembly or components when used with any BRADCO 3-point hitch type backhoe. Since many models of tractors have standard category hitches and backhoes have standard category attaching points, it is possible to mount tractor or backhoe combinations that are not compatible.

DEALERS AND/OR OWNERS MUST DETERMINE THAT COMPATIBIL-

ITY BETWEEN THE TRACTOR AND BACKHOE EXISTS.

Compatibility includes, but is not limited to items such as operator clearance, hitch component strength, tractor case strength and hydraulics.

Suggestions given as to hitch categories and horsepower ranges used with various models of backhoes are suggestions only and not recommendations as to suitability of any combination of tractors and backhoes.

BRADCO also manufactures solid 4-point mounting kits for many models of tractors. These kits do NOT mount to the 3-point hitch. If in doubt about your hitch campatibility, solid 4-point mounting type kit and backhoe should be used.
