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.
These instructions have been compiled from extensive field experience and engineering data. Some informa­tion may be general in nature due to unknown and varying conditions. However, through experience and these instructions, you should be able to develop pro­cedures suitable to your particular situation.
The illustrations and data used in this manual were cur­rent at the time of printing, but due to possible in-line production changes, your machine may vary slightly in detail. We reserve the right to redesign and change the machines as may be necessary without notification.
Figure 1. Backhoe Directions
Throughout this manual, references are made to right, left, forward and rearward directions. These are deter­mined from the backhoe operator seat position facing rearward as shown in Figure 1.
Some illustrations in this manual show the
backhoe with safety shields removed to provide a better view. The backhoe should never be operated with any safety shielding removed.
Terms for backhoe components have some variations throughout the industry. We use SAE designations as shown in Figure 2.

INSTALLATION
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.
SAFETY RULES
ATTENTION! BECOME ALERT! YOUR SAFETY IS INVOLVED!
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
BH6500/7500/9000_SR (Rev. 6/23/2006)
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.
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.

WARNING
CAUTION
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 pages 7 to 11.
Never put backhoe into service unless backhoe manufacturer's 3-point hitch Saf-T-Lok 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.)

START AND STOP OPERATION
Operate tractor PTO at 540 RPM. Do not exceed.
An optional tractor-driven PTO pump supplies hydraulic pressure for backhoe operation. Instructions for engag­ing and disengaging the PTO are in your tractor man­ual. Learn how to disengage PTO quickly should an emergency occur.
Never exceed 540 rpm. Operating the pump in excess of 540 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.
When operating controls, always sit in backhoe seat.
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 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.
12 Operation
Figure 1. Backhoe Swing Area.
MAN0450 (10/28/2005)
Page 13
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 1, 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
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.
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 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.
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 2.
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 (not to exceed 540 rpm).
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 degrees each way the first few times. Gradually increase arc.
MAN0450 (10/28/2005)
Figure 2. Operator’s Controls (Typical View)
Operation 13
Page 14
After becoming familiar with the backhoe operation,
WARNING
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.
BH80-X SWING SPEED CONTROL
The swing speed control valve is located on the back side of the console on BH80-X backhoes only. This controls the speed of the swing cylinders and allows for easier operation in tight areas. Turn knob to the right to Decrease swing speed and to the left to increase swing speed.
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.
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.
Figure 3. Starting Position
To start the excavation, position backhoe as shown in Figure 3 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.
Figure 4. Fill Bucket
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
Refer to Figure 5.
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.

MAN0450 (10/28/2005)
Page 17
NOTE: Circuit must be complete to prevent damage to
tractor hydraulic system.
Figure 9. Tractors with Open-Center Valves
MECHANICAL THUMB (OPTIONAL)
The mechanical thumb is used for grabbing objects and securing them between the thumb and the bucket.
Become familiar with the geometry and extra weight the thumb adds to the backhoe before operating. Large heavy objects such as rocks and logs can increase momentum when pivoting backhoe to the side. DO NOT make sudden stops and starts. Be extremely careful lifting and moving long items such as poles or tree limbs which may extend beyond the normal back­hoe operating area.
Improper usage can also damage the thumb or back­hoe. DO NOT use the thumb to rake material, push or pull material, use the side of the thumb to move mate­rial, use as a lifting devise with chain or rope, or as a pry bar to dislodge objects.
Place thumb in operating position by selecting an appropriate pin location on the telescoping tube. Rotate the bucket to hold material against the thumb.
When normal backhoe operation is required, place thumb in storage position. Remove pin, rotate thumb up against dipper, and insert pin to lock thumb into position.
PRE-OPERATION CHECK LIST
(OWNER'S RESPONSIBILITY)
The operator should perform the following check list before operating 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 high-
strength top link pin, provided with tractor, is used to attach top link to tractor.
___ Use a 3/4" x 3-1/2" 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.

WARNING
CAUTION
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.
Always back lock nut off and screw fitting all the way in for fittings that use O-rings for sealing. Then hold in
position and tighten lock nut.
RELIEF VALVE
BH70-X
This valve is pre-set at the factory to prevent system pressure from exceeding 2030 psi. Do not attempt to reset the valve for open-center hydraulic systems. If valve is malfunctioning, replace it with an authorized factory replacement part or have service done by a qualified dealer.
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.
HYDRAULIC HOSES AND FITTINGS
IMPORTANT
Fittings with O-rings and flange do not require
additional sealant; replace damaged O-rings.
Hydraulic hoses are severely worked on a backhoe. Examine them daily and replace if necessary. Hose routing is very important. Make certain hoses can move freely, without kinking, and cannot be damaged or cut by backhoe action.
When tightening hoses and fittings, always use two wrenches: one to hold hose and one to tighten fitting. This will prevent hose from twisting and kinking.
Figure 10. Relief Valve, BH70-X

WARNING
CAUTION
WARNING
The information in this section is written for dealer ser­vice personnel. The repair described here requires special skills and tools. If your shop is not properly equipped or your mechanics are not properly trained in this type of repair, it may be more time and cost effec­tive to replace complete assemblies.
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.
Adjustment of system relief pressure must be done by a qualified, experienced dealership. Incor­rect adjustment can result in system failures and serious personal injury.
No individual parts are available for relief valve. Replace entire assembly if required.
Pressure Setting Adjustment
NOTE: Before changing the pressure setting on the
valve, determine tractor hydraulic system pressure. Many tractors do not create 2000 psi. If your tractor does not create 2000 psi, changing the relief valve set­ting will not improve the backhoe performance.
To adjust relief valve setting, place a 3000 psi pressure gauge in the line attached to the valve inlet (IN) port. Remove cap from top of main relief (1, Figure 13). Turn adjusting screw clockwise to increase pressure and counter clockwise to decrease pressure. Start tractor and set throttle for full engine speed. Move right stabi­lizer control lever to raise stabilizer to transport position and hold the lever so full pressure builds. Adjust screw to attain 2000 psi. Shut off tractor and replace cap.
Port Relief Valves
Pressure settings on port relief valves are preset at the factory. Although they are adjustable, they must not be reset in the field using backhoe hydraulic system. An incorrect setting could cause hydraulic pump to fail or backhoe cylinder rods to buckle.
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.

ADJUST CONTROL VALVE LINKAGE
WARNING
Reconnect control linkage to valve.
Relief valve adjustment requires a test bench and accurate gauges.
Control handles should be positioned as shown.
When completing a maintenance function on the valve, perform a functional test by placing control handles in their various positions and make certain the correct operation occurs corresponding to the decals on the operator's console. Pay specific attention to the float position of the boom. Do not operate backhoe if func­tions differ from the decal.
If the functions differ from the decal, check to make sure control linkage is correctly installed and check plumbing schematics to make sure hoses are correctly connected.
Adjusting System Relief Valve Pressure
Adjustment of system relief pressure must be done by a qualified, experienced dealership. Incor­rect adjustment can result in system failures and serious personal injury.
NOTE: Before changing the pressure setting on the
valve, determine tractor hydraulic system pressure. Many tractors do not create 2000 psi. If your tractor does not create 2000 psi, changing the relief valve set­ting will not improve the backhoe performance.
Place a pressure gauge in the pump pressure line at the relief valve. When installing pressure gauge, be sure to use steel fittings that will withstand working pressure up to 5000 psi.
Remove cap nut (6a). Adjusting screw (6c) has a hex socket - rotate screw clockwise to increase pressure and counter-clockwise to decrease pressure.
Start tractor and engage PTO (for pump kits) set throt­tle at PTO speed. Set system relief valve pressure at 2470 psi. When pressure is adjusted, shut tractor PTO and tractor off. Replace cap nut (6a) on system valve.

GENERAL ASSEMBLY INSTRUCTIONS
Backhoe assembly is the responsibility of the WOODS dealer. The backhoe should be delivered to the owner completely assembled, lubricated and adjusted for nor­mal operating conditions.
Set backhoe up as received from the factory with these instructions and illustrations.
The backhoe must only be mounted with a tractor 3­point hitch using WOODS 3-Point Mount kit or a WOODS sub-frame kit. See WOODS 3-Point Mount manual for mount installation instructions.
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.
When mounting this backhoe on a tractor using a sub­frame mount, special assembly instructions (which are contained in another manual furnished with the sub­frame) apply to some of the assembly procedures.
The backhoe is shipped partially assembled. Assembly will be easier if components are aligned and loosely assembled before tightening hardware.
NOTE: References to right, left, forward and rearward directions are determined from the backhoe operator seat position facing rearward.
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.
STABILIZER INSTALLATION
Remove stabilizer arms from pallet.
Remove pivot pins (27) from their shipping position. Attach stabilizer arm (20) to main frame (3) with pivot pin (27) and secure with snap ring (67).
Attach stabilizer cylinder (5) to stabilizer arm with pivot pin (25) and secure with two cotter pins (38).
Figure 18. Backhoe Directions
Keep all persons away from operator control area while performing adjustments, service, or maintenance.
Only mount this backhoe on Category 1 tractors with 800 lb. lift capacity at 24" behind 3-point lift arm hitch balls.
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.

HYDRAULIC INSTALLATION
Refer to Figure 21.
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. CON-
MAN0450 (10/28/2005)
TACT A PHYSICIAN IMMEDIATELY IF FLUID ENTERS SKIN OR EYES. DO NOT DELAY.
Make sure shields and guards are properly
installed and in good condition. Replace if damaged.
Power to the backhoe can be supplied directly from the tractor hydraulic system. A hydraulic requirement of 5­7 gallons per minute and 2000 PSI (BH70-X) or 2400 psi (BH80-X) is necessary to operate the backhoe effi­ciently. 3/8" diameter hoses (SAE 100 R1 with 2500 PSI working pressure) should be used to connect the hydraulic source to the backhoe valve. These hoses must be long enough to allow ease of removal or attachment of backhoe. Hoses must include external shielding to prevent oil from spraying on operator if hose fails.
Open-Center
Refer to Figure 21.
Remove the console cover from the backhoe to gain access to control valve (1). Connect 3/8" hoses (2 & 3) to the backhoe inlet and outlet ports. Install couplers (4) compatible to the tractor on opposite end of the 3/8" hoses. Determine the direction of flow and connect tractor pressure hose (6) to the inlet side of the control valve (under left foot rest).
Note: The backhoe will not function if oil is routed back­wards through the valve. Connect the tractor return hose (5) to the control valve outlet port. Tighten all fit-
Assembly 31

Attach hose (13) between elbows (14) and (11). Secure hose ends using hose clamps(12).
Install elbow (17) and hose (24) to the outlet side of the hydraulic pump.
NOTE: To properly install hydraulic fittings with O-rings, completely loosen lock nut, screw fitting completely in, hold in position and tighten locknut using two wrenches.
Remove 90° steel tubes from the IN and OUT ports on the backhoe control valve.
HYDRAULIC PUMP INSTALLATION (OPTIONAL)
Refer to Figure 22.
IMPORTANT
Clean all fittings and use care to prevent for-
eign material from entering hydraulic system.
Attach hose (23) to the backhoe control valve OUT port and hose (24) to the IN port.
Attach pump mounting bracket (18) to the hydraulic pump (16) using two cap screws (19) and lock nuts (20).
When backhoe is attached to tractor, it may be neces­sary to reposition filter and hoses to eliminate interfer­ence.

TION
On tractors with non-standard drawbars, it may be nec­essary to modify pump bracket by enlarging the open­ing. Bracket may also be inverted and retained on the top link bar. Whatever mounting is used, it is important that pump be restrained from rotating.
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.
Make sure spring-activated locking pin or collar slides freely and is seated firmly in tractor PTO spline groove.
Attach pump mounting plate (18) to pump with bolts (19) and nuts (20), Figure 22.
Check all hydraulic fittings and lines to be sure they are tight and free of kinks and twists.
SEAT INSTALLATION AND ADJUSTMENT
The seat may be adjusted fore, aft, up and down for operator comfort. It is necessary to use the two adjust­ments together. Moving the seat down also moves it forward, moving it up also moves it rearward. The fore and aft adjustment may be used with the up and down adjustment to obtain desired position. Never operate the backhoe unless manufacturer's 3-point hitch Saf-T­Lok Limiter or sub-frame has been installed, adjusted and operator's area (shown in decal 1011992, see decal page 11) is free from obstructions.
INSTALL OPTIONAL STABILIZER STREET PAD
1. Attach two rubber stabilizer pads (7) to the bottom
stabilizer pad (2) using three lock nuts (6).
Figure 23. Pump Mounting Bracket Installation
If you are using a sub-frame mounting, refer to the pump mounting instructions provided with the sub­frame.
The pump mounting bracket is designed to slip over tractor drawbar. The best installation is to place bracket offset toward tractor and pump offset down; however, offset may be reversed if interference occurs, Figure

Always tighten hardware to these values unless a different torque value or tightening procedure is listed for a specific application. Fasteners must always be replaced with the same grade as specified in the manual parts list. Always use the proper tool for tightening hardware: SAE for SAE hardware and Metric for metric hardware. Make sure fastener threads are clean and you start thread engagement properly. All torque values are given to specifications used on hardware defined by SAE J1701 MAR 99 & J1701M JUL 96.
