SAFETY HIGHLIGHTS

Read and understand all manuals and instructional material listed on cover, inside front cover and introduction page of this Manual before starting, operating or performing maintenance procedures on this equipment.

Operators of this equipment must have successfully completed a training course in the safe operation of this type of material handling equipment.

Regardless of previous experience operating similar equipment, the operator must be given sufficient opportunity to practice with the handler in a safe, open area (not hazardous to people or property) to gain operating skills and the proper “feel” for controls and operating clearances required for safe, efficient operation.

GRADALL Material Handlers are equipped with a right-side rearview mirror. This mirror is intended as an operator’s aid and does not replace the requirement for line-of-sight. Certain job site and machine conditions may require use of a signal person to help the operator when picking, placing or transporting a load. Never operate the handler until you know pick-up point, line of travel and landing point are clear. Always be aware that objects in mirror are closer than they appear.

Safety Precautions

Make sure all DANGER, WARNING, CAUTION and INSTRUCTIONAL DECALS are in place and can be read. Clean or replace decals as required.

Ensure handler is on a firm, level surface before lifting or placing load. Have surface leveled if necessary. Unit can tip over if load is raised with handler

on a soft or uneven surface.

Always look in the direction of travel. Reduce speed and be especially careful when traveling in reverse and/or turning. Be aware of tail swing due to rear-pivot steering.

WATCH FOR THESE SYMBOLS ; THEY CALL YOUR ATTENTION TO SAFETY NOTICES.

DANGER

This symbol indicates an extreme hazard which will result in high probability of death or serious injury if proper precautions are not taken.

WARNING

This symbol indicates a hazard which could result in death or serious injury if proper precautions are not taken.

CAUTION

This symbol indicates a hazard which may result in injury or damage to equipment or property if proper precautions are not taken.

If load or conditions obstruct view, use a signal person when lifting, carrying or placing a load.

Loose clothing can get caught in moving machinery and can also cause accidental actuation of controls. Dress properly for the job.

Be alert to any unusual response to controls. If unusual response is noticed, position handler in a safe area, lower forks to ground, apply parking brake, stop engine and remove key from ignition switch. Tag steering wheel to forbid operation and notify maintenance personnel.

Keep hands, gloves, shoes, control knobs and pedals clean. Slippery controls

can cause accidents. Keep a firm grip on the steering wheel when traveling.

Load capacities are based on load center being within 24 inches (610mm) from front vertical face of forks.

Never service the handler with the engine running.

Release trapped pressure before disconnecting, opening or removing any

hydraulic component.

WARNING

Operator must be seated with seat belt fastened, forward reverse lever in “Neutral” position, parking brake applied and all hydraulic controls in “Neutral” before starting engine.

1.1

Keep all windows and mirror(s) clean. Adjust mirror(s) as visibility, before and during opera

tion.

required for maximum

Never permit diesel engine to run out of fuel. Doing so can cause severe engine damage.

DO NOT burn or drill holes in forks. Modifying any part of machine or attachment may affect machine capacity and/or stability.

Keep head, arms, hands, legs and all other body parts inside the operator’s cab at all times.

DO NOT approach power lines, overhead or underground cables or other power sources with any part of your material handler or load unless all local, state/ provincial and federal regulations have been met and the appropriate utility company has been contacted to de-energize the lines.

Whenever leaving the cab, perform standard shut-down procedure:

Standard Shut-Down Procedure

Position the handler in a safe location, apply parking brake, lower forks to ground, move all controls to minutes.

Stop engine and remove ignition key. Block wheels.

“Neutral”, allow engine to run at low idle for 3 to 5

Pinch Points

Stay clear of pinch points and rotating parts on the material handler. Getting caught in a pinch point or a moving part can cause serious injury or death. Before performing any maintenance on machine, follow the “STANDARD SHUT-DOWN PROCEDURE”.

WARNING

Cold-Weather Starting Aids

In cold approved starting aids employ ether. If your handler is equipped with an ether starting aid, the following applies:

weather situations, a supplemental starting aid may be required.

Gradall-

WARNING

Operator must be seated with seat belt fastened, forward/reverse lever in “Neutral” position, parking brake applied and all hydraulic controls in “Neutral” before starting engine.

CAUTION

Turning ignition switch to “START” position while engine flywheel is rotating may cause serious damage to engine and/or starting motor.

NOTE!

Engine will not start unless forward/ reverse lever is in “Neutral” and parking brake switch is applied.

Cummins Engine

• Hold switch on for 3 seconds to fill valve.

• Release switch to discharge ether while cranking engine.

• As engine starts, use additional ether as required to keep engine running.

Deere Engine

• Ether application is triggered by temperature gauge located on engine.

• At start-up, temperature gauge on engine will detect if ether is needed. Follow normal start-up procedure, shown above.

• Ether is employed and additional will be released if needed, to keep engine running.

• A second battery is added for additional cold-cranking capacity.

Battery-Boosted Starting

If you ever have to battery-boost start (jump-start) your handler, proceed as follows:

• Never allow vehicles to touch

• Connect the positive (+) jumper cable to positive (+) post of discharged battery

• Connect opposite end of positive (+) jumper cable to positive (+) post of booster battery

• Connect the negative (-) jumper cable to negative (-) post on booster battery

• Connect opposite end of negative (-) jumper cable to ground point on machine away from discharged battery

• Follow standard starting procedures

• Remove cables in reverse order after machine has started

Normal Engine Operation

Observe gauges frequently to be sure all engine systems are functioning properly.

The voltmeter shows the “charge/discharge” state of the battery charging system. With the engine running, meter should indicate 13.5 to 14 volts. With engine stopped, meter indicates battery charge (12 volts). The alternator indicator light glows (red) to indicate alternator is not charging.

Be alert for unusual noises or vibration. When an unusual condition is noticed, park machine in safe position and perform standard shut-down procedure. See Page 1.1. Report condition to your supervisor or maintenance personnel.

Avoid prolonged idling. Idling causes engine temperature to drop and this permits formation of heavy carbon deposits and dilution of lubricating oil by incompletely-burned fuel. If the engine is not being used, turn it off.

Stopping the Engine

• To stop engine, perform standard shut-down procedure.

• Operate engine at low idle for 3 to 5 minutes before turning it off. This allows engine coolant and lubricating oil to carry excessive heat away from critical engine areas, including turbocharger.

• Do not “gun” engine before shut down: This practice causes incompletelyburned fuel to remove oil film from cylinder walls and dilute lubricant in crankcase.

CAUTION

Always keep engine cover closed while engine is running.

John Deere Engine Shut-Down Protection Feature

The feature monitors coolant temperature, oil pressure and charge-air temperature. If any of the listed items cause a fault in the system the check

engine light will illuminate and the engine will shut down after 30 seconds. Within that 30 second period, lower the boom and apply parking brake. Report condition to your supervisor or maintenance personnel.

NOTE!

In the event of needing to delay a shutdown, See “Shutdown

Override Switch,” Page 3.2.

NOTE!

In the event of engine or hydraulic failure, parking brakes can be released for towing. See “To

Release Parking Brake,” Page

BRAKE SYSTEM

General

The brake system includes a service brake and a parking brake. Service and parking brakes are applied through wet disc brake packs located within axle housing.

WARNING

Because service braking and “inching” (slow travel) functions overlap, some features of inching will be discussed here. See “Drive Train” Section, Page

10.0, for additional information on inching travel. (See Figure 3-1 for layout of controls)

Inching Travel

Overlap between braking and inching occurs because the same pedal controls both functions; also because both functions control travel speed. However, the methods of controlling travel speed are quite different. Service braking involves a controlled stopping force applied to the front wheels. Inching involves a controlled driving force applied to the driving wheels.

Figure 7-1

LOWEST INCHING TRAVEL SPEED

SERVICE BRAKING

Most of the inching travel pedal stroke controls the speed of inching travel. As the pedal nears the bottom of its stroke, service brakes are engaged.

SERVICE BRAKE/INCHING

TRAVEL PEDAL

HIGHEST INCHING TRAVEL SPEED

Practice inching/braking in a safe, open area until you are thoroughly familiar with handler response.

WARNING

If power-assist feature should fail for any reason, it would require greater effort to apply service brake. It is extremely important

that you never stop the engine while traveling. If power assist

fails, stop as soon as possible. Do not drive the handler until problem has been corrected.

Service Brakes

epressing service brake/inching travel pedal to braking

portion of pedal travel causes controlled hydraulic pressure to be applied to service brakes. The greater the pedal travel, the greater the braking force.

If power-assist fails, it will require much greater force on pedal to apply brake, and stopping distance will be greater.

Parking Brakes

The parking brakes are spring-applied and hydraulically-released.

Hydraulic power to release parking brakes is provided by the hydraulic system and is controlled by the parking brake switch located on the dashboard.

With the engine running and the parking brake switch “Off,” parking brakes are disengaged. Moving the switch to “On” releases hydraulic pressure to apply the parking brakes. With switch in “ON” position, four-wheel drive is disabled.

WARNING

Always move parking brake switch to “On” position before leaving cab.

Never stop engine while traveling. Parking brake will be fully-applied and unit may stop abruptly. A sudden stop could cause load loss.

NOTE!

In the event of engine or hydraulic failure, parking brakes can be released for towing. See “To

Release Parking Brake,” Page

16.1.

PARKING THE HANDLER

Precautions

• Avoid parking on slopes or near an excavation.

• Park on level ground and chock wheels.

• Avoid parking on roads or highways. If it cannot be avoided,be sure to display warning flags during day and flares or flashing lights at night.

• Position boom-head or attachment on ground; never leave machine with boom in air.

• If parking on a slope cannot be avoided, position the handler at a right angle across the slope, straighten rear wheels and chock all wheels.

Parking procedure

1. Using service brake, stop the handler in an appropriate parking area.

2. Move parking brake switch to “On.”

3. Shift forward/reverse lever to “Neutral.”

4. Position attachment on ground.

5. Allow engine to cool at idle speed for 3 to 5 minutes, stop engine and remove ignition key.

6. Chock wheels as an extra precaution against rolling.

7. Fill fuel tank to minimize condensation.

8. Lock cab and install protective covers, if so-equipped.

9. Disconnect batteries if unit is in an area where tampering is a risk.

9.0

• Rear-wheel power steering is provided to reduce operator fatigue and to permit high maneuverability in close quarters.

• It is imperative that the operator practice maneuvering the handler in a safe, open area to become thoroughly familiar with steering response and clearance required for tail swing and load when turning.

STEERING SYSTEM

WARNING

Be alert for any increase in effort needed to steer. If any difference is noted, notify maintenance personnel immediately. If power assist feature should fail for any reason, IT WOULD BECOME VERY DIFFICULT TO STEER. For this reason it is extremely important that you NEVER TURN ENGINE OFF WHILE TRAVELING.

In the event power steering fails, stop as soon as possible. Do not drive handler until problem has been corrected.

10.0

DRIVE TRAIN

General

The Material Handler covered by this Manual is equipped with hydrostatic drive. From the operator’s standpoint, operation is similar to driving a vehicle equipped with an automatic transmission.

Major components of the system include a front drive axle with a differential and planetaries. The differential receives torque from a variable-displacement piston pump and a motor.

This combination of components eliminates the need for a conventional mechanical transmission and also provides inching travel.

These handlers also have piston motors to provide torque to rear-wheel drive hubs, as well as an electrically-controlled valve which functions to restore tractive effort if conditions cause a wheel to spin.

Operation

Normal Travel. Direction of travel is selected by moving forward/reverse lever

forward for forward travel, backward for reverse travel. Move lever to center position for “Neutral”. (See Figure 3-1 for layout of controls)

WARNING

If hydrostatic drive system senses increased travel load, the system will compensate automatically by reducing travel speed to match load and engine RPM.

Inching Travel: Inching travel is provided to permit slow travel speed while maintaining high engine speed for other handler functions.

The service brake/inching travel pedal controls inching travel.

The upper portion of pedal travel actuates a valve which controls travel pump output. The greater the pedal travel, the less the pump flow; the slower the travel.

The lower portion of pedal travel actuates the service brake. The greater the pedal travel, the stronger the brake application. Travel flow is further reduced when brakes begin to apply. (See Figure 7-1)

Four-Wheel Drive: When required by travel conditions, rear-wheel (fourwheel) drive can be engaged by moving switch to “4x4” position. Return unit to two-wheel drive by moving switch to “4x2” position.

Four-wheel drive can be engaged and disengaged while traveling.

When parking brake is applied, four-wheel drive is disabled.

Traction-Lock Switch: This switch (pedal) controls the traction-lock valve which functions to restore tractive effort when a wheel spins in four-wheel drive.

Bring handler to a complete stop before shifting forward/reverse lever when carrying a load. A sudden change in direction of travel could reduce stability and/or cause load to shift or fall.

WARNING

Practice inching/braking in a safe, open area until you are thoroughly familiar with response of machine to pedal travel.

When switch pedal is depressed and held, traction-lock valve functions to cause delivery of full drive pressure to wheels of other axle, regardless of low pressure at spinning wheel.

DO NOT engage traction-lock function on improved surfaces. Unit must be in four-wheel drive to engage the traction-lock function.

DO NOT engage traction-lock function while wheels are turning. Return engine to idle, engage traction-lock and increase RPM. Disengage after traction resumes while in motion.

LEVELING THE HANDLER

“Leveling” means positioning the handler so that it is level from side to side (left to right).

A level indicator is located in the upper right corner of front window frame to permit operator to determine whether handler frame level. (See Figure 3-1)

There are four very important things to remember about handler leveling:

1. Never engage a load or lift a load more than four feet (1.2m) above

ground unless handler is level.

2. A handler with the boom raised and/or an attachment installed is a partially-

loaded handler.

3. Once the handler frame is level and the handler has raised a load more

than four feet (1.2m) above ground, it must not be moved from this position if such movement could change the level condition. Do not use sway to level handler with load more than four feet (1.2m) above ground.

4. The combination of side tilt and load can cause the handler to tip over.

Two ways to level the handler with stabilizers up :

The surface which will support the handler can be leveled. This method must be chosen if it will be necessary to move the handler from its position after the load has been raised over four feet (1.2m) from ground AND such movement could change the level condition.

WARNING

Raising the boom (loaded or unloaded) when handler is leaning to one side could cause machine to tip over with little or no warning and cause serious injury or death.

Remember: The supporting surface must be large enough, smooth enough and firm enough to keep the handler level when it is moved from its position.

The handler may be leveled by means of the frame-leveling system. This method may be chosen when it will not be necessary to move the handler from its position after the load has been raised above four feet (1.2m) from ground - OR - when such movement will not change the level condition of the handler.

Always determine best position for handler to raise load from its present location and also to position load at its destination. THEN determine which method of leveling will be required at each location.

FINALLY, consider terrain between present location of load and its destination. Never attempt to transport a load across terrain which could cause handler to tip over.

Leveling Handler Frame:

The handler is designed to permit tilting main frame 8° to left or right to compensate for uneven ground conditions.

The rear axle pivots at the midpoint of the main frame to help ensure that all wheels will remain in contact with the ground.

A hydraulic cylinder provides a rigid connection between front axle and main frame to help ensure a solid work platform and to tilt main frame to left or right.

The 544D-10 is equipped with rear-axle stabilization. This system includes a hydraulic cylinder attached between the frame and the rear axle, as well as flow-restricting valving. This system dampens rear-axle oscillation whenever the boom is raised over 40° from level. However, the system never locks

the rear axle and is not designed to increase lateral stability.

WARNING

Always move boom to carry position (horizontal or below) before leveling frame. Attempting to level machine with boom raised could cause it to tip over.

11.1

Leveling Procedure:

1. Position machine in best location to lift or place load and apply parking brake.

WARNING

2. Observe level indicator to determine whether machine must be leveled. Note position of indicator for later realignment.

3. If necessary to level handler, position boom in carry position and level machine with the lever.

4. Lift or place load as appropriate.

5. Retract and lower boom to carry position.

6. Realign frame to position noted in step 2.

OPERATING PROCEDURE & TECHNIQUES

Hydraulic Controls

All boom and attachment movements are governed by hydraulic controls. Rapid, jerky operation of hydraulic controls will cause rapid, jerky movement of the load. Such movements can cause the load to shift or fall or may cause the machine to tip over.

Feathering

Feathering is a control operation technique used for smooth operation. To feather controls, move control lever very slowly until function begins to move, then gradually move lever further until function is moving at desired speed. Gradually move lever toward “Neutral” as load approaches destination. Continue to reduce load speed to bring load to a smooth stop. Feathering effect can be increased by reducing engine speed at beginning and near end of load movement.

Boom Control Joystick

The boom control joystick can be positioned to activate individual boom movements or combinations of boom movements as illustrated:

BOOM

With boom raised above horizontal, forks can be inserted under a load by moving boom control joystick forward and to the right until forks move forward horizontally.

With boom raised above horizontal, forks can be removed from a load by moving boom control joystick back and to the left until forks move rearward horizontally.

With boom lowered below horizontal, forks can be inserted under

a load by moving

boom control joystick back and to the right until forks move forward horizontally.

With boom lowered below horizontal, forks can be removed from a load by moving boom control joystick forward and to the left until forks move rearward horizontally.

The closer the boom to horizontal, the less boom raise/lower movement required for inserting and removing forks.
