SECTION 4. MACHINE OPERATION

4.1 DESCRIPTION

This machine is a self-propelled hydraulic lift equipped with a work platform on the end of an elevating and rotating boom.

The JLG Lift has a primary operator Control Station in the platform. From this Control Station, the operator can drive and steer the machine in both forward and reverse directions. The operator can raise, lower, extend or retract the tower boom; raise, lower, extend or retract the main boom; swing the boom to the left or right; and rotate the platform around the boom tip. Standard boom swing is 360° continuous left and right of the stowed position. The machine has a Ground Control Station which will override the Platform Control Station. Ground Controls operate boom lift, telescope, swing, and rotate and are to be used only in an emergency to lower the platform to the ground should the operator in the platform be unable to do so.

4.2 OPERATING CHARACTERISTICS AND LIMITATIONS

Capacities

The boom can be raised above horizontal with or without any load in the platform if:

1. Machine is positioned on a smooth, firm and level surface.

2. Load is within manufacturer’s rated design capacity.

3. All machine systems are functioning properly.

4. Proper tire pressure exists in the tires.

5. Machine is as originally equipped from JLG.

Stability

Machine stability is based on two (2) positions which are called FORWARD stability and BACKWARD stability. The machine’s position of least FORWARD stability is shown in Figure 4-1., Position of Least Forward Stability, and it’s position of least BACKWARD stability is shown in Figure 4-2., Position of Least Backward Stability.

5.2 INCIDENT NOTIFICATION

JLG Industries, Inc. must be notified immediately of any incident involving a JLG product. Even if no injury or property damage is evident, the factory should be contacted by telephone and provided with all necessary details.

In USA: JLG Phone: 877-JLG-SAFE (554-7233) (8am till 4:45pm EST)

Outside USA: 240-420-2661

E-mail:

ProductSafety@JLG.com

Failure to notify the manufacturer of an incident involving a JLG Industries product within 48 hours of such an occurrence may void any warranty consideration on that particular machine.

FOLLOWING ANY ACCIDENT, THOROUGHLY INSPECT THE MACHINE AND TEST ALL FUNCTIONS FIRST FROM THE GROUND CONTROLS, THEN FROM THE PLATFORM CONTROLS. DO NOT LIFT ABOVE 10 FT. (3 M) UNTIL YOU ARE SURE THAT ALL DAMAGE HAS BEEN REPAIRED, IF REQUIRED, AND THAT ALL CONTROLS ARE OPERATING CORRECTLY.

5.3 EMERGENCY TOWING PROCEDURES

RUNAWAY VEHICLE/MACHINE HAZARD. MACHINE HAS NO TOWING BRAKES. TOWING VEHICLE MUST BE ABLE TO CONTROL MACHINE AT ALL TIMES. ON-HIGHWAY TOWING NOT PERMITTED. FAILURE TO FOLLOW INSTRUCTIONS COULD CAUSE SERIOUS INJURY OR DEATH.

Towing the machine is prohibited, unless properly equipped. However, provisions for moving the machine, in case of a malfunction or power failure, have been incorporated. The following procedures are to be used ONLY for emergency movement to a suitable maintenance area.

1. Chock wheels securely.

2. Disengage drive hubs by reversing disconnect caps.

3121213 – JLG Lift – 5-1

SECTION 5 - EMERGENCY PROCEDURES

3. Connect suitable equipment, remove chocks, and move machine.

After moving machine, complete the following procedures:

1. Position machine on a firm, level surface.

2. Chock wheels securely.

3. Engage drive hubs by reversing disconnect caps on

hubs.

4. Remove chocks from wheels.

5.4 EMERGENCY CONTROLS AND THEIR LOCATIONS

Ignition/Emergency Stop Switch

CHECK MACHINE DAILY TO MAKE SURE IGNITION/EMERGENCY STOP BUTTON IS IN PLACE AND THAT GROUND CONTROL INSTRUCTIONS ARE IN PLACE AND LEGIBLE.

Ground Control Station

The Ground Control Station is located on the front right side of the turntable. The controls on this panel provide the means for overriding the platform controls and for controlling the platform level, platform rotate, tower boom lift, tower boom telescope, main boom lift, main boom telescope, swing, creep speed and activating auxiliary power from the ground. Place the station SELECT SWITCH in the GROUND position and operate the proper controller or control switch.

This switch is a large red button located on the platform console panel and also on the ground control remote box. With the button pulled out, power is supplied to the start button. When the red button is depressed it will shut off power and immediately stop the machine. The corresponding button, ground or platform, must be pulled out in order for the machine to operate from the desired control station.

Auxiliary Power

A toggle-type auxiliary power control switch is located on the platform control station and another is located on the ground control station. Operation of either switch turns on the electrically driven auxiliary hydraulic pump. Auxiliary power should be used in case of failure of the main power plant. The auxiliary pump will operate tower lift up and down, main lift up and down, tower telescope in and out, main telescope in and out, swing left and right, platform rotate and platform level.

5-2 – JLG Lift – 3121213

SECTION 5 - EMERGENCY PROCEDURES

To activate auxiliary power from the platform:

1. Position PLATFORM/GROUND SELECT SWITCH to PLATFORM.

2. Position MASTER SWITCH to ON.

3. Depress and hold footswitch.

4. Operate appropriate control switch or controller for

desired function and hold.

5. Position AUXILIARY POWER switch to ON and hold.

6. Release AUXILIARY POWER switch and appropriate

control switch or controller and footswitch.

7. Position MASTER SWITCH to OFF.

To activate auxiliary power from the ground control station:

1. Position PLATFORM/GROUND SELECT SWITCH to GROUND.

2. Position MASTER SWITCH to ON.

3. Operate appropriate control switch or controller for

desired function and hold.

4. Position AUXILIARY POWER switch to ON and hold.

5. Release AUXILIARY POWER switch and appropriate

control switch or controller.

6. Position MASTER SWITCH to OFF.

Manual Descent and Retraction

The manual descent valves are used, in the event of total power failure, to retract the tower boom and lower the main boom using gravity. To operate the manual descent system, proceed as follows:

1. Remove manual descent pump handle from inside battery access door.

2. Open manual descent valves # 1 and # 2 by turning valve handles counterclockwise and close manual descent valve # 3 by turning valve handle clockwise.

3. Pump hydraulic hand pump until tight, or until Tower Telescope In and Main Lift Down begin retracting. To stop functions, open valve # 3.

4. Tower Telescope In and Main Lift Down can be operated independent of each other. To operate Tower Telescope In open valve # 1. To operate Main Lift Down open valve # 2.

5. When manual descent function has been completed, open all valves 1 full turn, then return pump handle to stowed position.

SECTION 5 - EMERGENCY PROCEDURES

5.5 EMERGENCY OPERATION

Use of Ground Controls

KNOW HOW TO USE THE GROUND CONTROLS IN AN EMERGENCY SITUATION.

Ground personnel must be thoroughly familiar with the machine operating characteristics and the ground control functions. Training should include operation of the machine, review and understanding of this section and hands-on operation of the controls in simulated emergencies.

Operator Unable to Control Machine

IF THE PLATFORM OPERATOR IS PINNED, TRAPPED OR UNABLE TO OPERATE OR CONTROL THE MACHINE:

DO NOT OPERATE WITH PRIMARY POWER SOURCE (ENGINE) IF PERSONS ARE PINNED OR TRAPPED. USE AUXILIARY POWER INSTEAD.

1. Operate the machine from ground controls ONLY with the assistance of other personnel and equipment (cranes, overhead hoists, etc.) as may be required to safely remove the danger or emergency condition.

2. Other qualified personnel on the platform may use the platform controls with regular or auxiliary power. DO NOT CONTINUE OPERATION IF CONTROLS DO NOT FUNCTION NORMALLY.

3. Prior to removing platform occupants, cranes, forklift trucks or other equipment which may be available are to be used to stabilize motion of the machine in case machine controls are inadequate or malfunction when used.

Platform or Boom Caught Overhead

If the platform or boom becomes jammed or snagged in overhead structures or equipment, do not continue operation of the machine from either the platform or the ground until the operator and all personnel are safely moved to a secure location. Only then should an attempt be made to free the platform using any necessary equipment and personnel. Do not operate controls to cause one or more wheels to leave the ground.

Following any accident, thoroughly inspect the machine and test all functions first from the ground controls, then from the platform controls. Do not lift above 3 meters until you are secure that all damage has been repaired, if required, and that all controls are operating correctly.
