WARNING

!

CAUTION

!

WARNING

!

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.

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.

JLG/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.

Be aware that when rotating the platform within indicated area on capacity charts, it can swing into tires. Be sure to allow clearance to avoid damage to tires.

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

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

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

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

When traveling at high rates of speed, use two wheel front steer mode and

slow the machine prior to turning.

Do not change steer mode while the machine is traveling. Change the

steer mode only when machine is stopped.

Always look in the direction of travel. Reduce speed and be especially careful when traveling in reverse and/or turning. Bring the machine to a complete stop before changing the direction of travel.

Travel in reverse only at slow rates of speed.

When turning, the forks on the four wheel steer machine sweep through an arc beyond the turn radius of the tires. Maintain adequate clearance between

the forks/load and other objects.

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.

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

SAFETY HIGHLIGHTS

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 .6m (24 inches) from front vertical face of forks.

Release trapped pressure before disconnecting, opening or removing any

hydraulic component.

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

Do not increase engine speed with the transmission in forward or reverse and the service brake pedal depressed in an attempt to get quicker

hydraulic performance. This could cause unexpected machine movement.

After bringing the material handler to a stop using the service brake, place the directional control lever in neutral, and set the park brake prior to lifting a load.

Allow the handler to slow down, or use the service brakes prior to down-shifting.

Do not downshift more than one gear at a time.

When traveling on downhill slopes, downshift to a lower gear and use the service brake as necessary to maintain a slow speed. Do not shift into neutral and

coast downhill.

DO NOT burn or drill holes in forks. Modifying any part of machine or attachment affects it’s capacity and/or stability of machine.

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’s hotline 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, lower forks/attachment to ground, apply park brake, move all controls to minutes. emergency stop button in run mode. Chock wheels.

Rotate control station selector switch to “off”, remove key and place

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

WARNING

!

Do not allow personnel to tamper with or operate the machine from the cab with personnel in the platform equipped with controls, except in an emergency.

Do not allow others to occupy cab while platform controls are in use.

TWO METHODS OF USING THE CAPACITY CHART.

SAMPLE ONLY - USE CHART IN CAB

Method 1

1. The operator must determine:

BOOM EXTENSION NUMBER where the load is to be placed.

BOOM ANGLE where the load is to be placed.

2. On the capacity chart, find the arc for the boom extension number, and follow it down to the boom angle.

3. The number in the load zone where these two cross is the maximum capacity for this lift. If the two cross at a division between zones, the smaller number must be used.

Method 2

1. The operator must determine:

HEIGHT where the load is to be placed.

DISTANCE from the front of the machine where the load is to be placed.

2. On the capacity chart, find the line for the height and follow it over to the distance.

3. The number in the load zone where the two cross is the maximum capacity for this lift. If the two cross at a division between zones, the smaller number must be used.

For each method, the number in the load zone must be equal to or greater than the weight of the load to be lifted. Determine the limits of the load zone on the capacity chart by boom angle AND boom extension number. Keep the load within theses limits.

9151-3207 REV.-

TIPOVER HAZARD. Failure to comply with instructions could result in death or serious injury.

The operator MUST:

1. Make sure the handler is on a firm, level surface before lifting or placing a load.

2. Make sure that the capacity charts are for the appropriate Gradall model.

3. Make sure that the Part Numver shown on the attachment's Serial Number Plate matches the Part Number shown on the capacity chart.

4. Be sure of the WEIGHT of the load to be lifted.

To be performed at beginning of each work shift. PERFORM “WALK-AROUND INSPECTION” AS DESCRIBED ON PAGES P6.2 & P6.3 IN THE TRANSFORMER SERIES WORK PLATFORM MANUAL LOCATED IN THE BACK OF THIS MANUAL. THIS INSPECTION IS A DAILY REQUIREMENT BEFORE OPERATING THIS MACHINE.

The safety, efficiency and service life of your handler will be increased by performing the operational checks listed below. Items preceded by an asterisk (*) are optional and may not be furnished on your machine.

Before entering the operator’s cab, check:

1. Engine oil level.

2. Hydraulic oil level.

3. Air Filter Restriction Indicator. If needle is in red area, filter is clogged and element must be cleaned or changed.

During warm-up period, check:

* 4. Heater, defroster and windshield wiper.

WARNING

!

Check all tires and rims periodically for damage due to impact. Replace before use if damage is detected.

* 5. Operating lights and rotating beacon.

6. Voltmeter-should show 13.5 to 14 volts.

When engine warms to operating range, check:

7. Transmission fluid level.

8. Service brake and parking brake.

9. Forward and reverse travel.

10. Each of the gear ranges.

11. Steering (in both directions) with engine at low idle. Check in each steering mode.

12. Horn and back-up alarm. Must be audible from inside operators cab with engine running.

13. All boom and attachment functions - operate smoothly and correctly.

14. Hydraulic Filter Condition Indicator - observe engine coolant temperature gauge after starting normal operation. When needle has been in operating range for an hour or so, stop handler in a safe area, apply parking brake, lower forks fully, shift forward/reverse lever to “Neutral” position and chock wheels. With engine running at full throttle, have an assistant check the Hydraulic Filter Condition Indicator. When bar gauge is in red area, filter is clogged and hydraulic oil is bypassing filter. Filter element must be changed before reaching bypass condition (change before needle reaches red area).

CAUTION

!

Keep engine cover closed while engine is running except when checking Transmission Oil Level and hydraulic filter condition indicator.

CAUTION

!

Continued operation with hydraulic fluid bypassing the filter may cause severe damage to hydraulic system components.

Complete all required maintenance before operating unit.

Cold-Weather Starting Aids

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

• All employed ether is triggered by temperature gauge located on engine.

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

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

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

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

NOTE!

Engine will not start unless transmission control lever is in “Neutral” and parking brake switch is applied.

If your machine is equipped with a cold start aid, do not spray additional ether into air cleaner.

If machine is not equipped with cold start aid, follow instructions listed in the engine manual supplied with machine.

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

ENGINE OPERATION

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).

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 shown on page 1.1.

• 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.

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.

Service Brakes

D

epressing the service brake pedal 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.

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

causes controlled hydraulic pressure to be

If power-assist feature should fail for any reason, it would require greater effort to apply service brake. If power assist fails, stop as soon as possible. Do not drive the handler until problem has been corrected.

Always move parking brake switch to “On” position before leaving cab. Never stop engine while traveling. Parking brake will be fully-applied and unit could stop abruptly. A sudden stop could cause load loss.

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, the transmission will not engage forward or reverse.

Always ensure that transmission control lever is in neutral before releasing park brake. Releasing park brake in either forward or reverse could cause the machine to move abruptly.

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 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 transmission control lever to “Neutral”.

4. Position attachment on ground.

5. Allow engine to cool at idle speed for 3 to 5 minutes, stop engine. Rotate control station selector switch to “off”, remove key and place emergency stop button in run mode.

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.

STEERING SYSTEM

WARNING

!

• Three modes of steering are provided as standard equipment. A three position switch on the dashboard allows the operator to select the steering mode.

• 4-wheel circle steer allows for tight turns and better maneuverability in close quarters.

• 4-wheel crab steering allows the machine to move sideways at an angle.

• 2-wheel front steer is used for high speed travel.

• 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 fork swing and load when turning.

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.

Use only 2-wheel steer when traveling at high speeds. Never use 4-wheel circle steer at high speeds, sharp turns could cause machine roll-over.
