3.1 GENERAL

THE MANUFACTURER HAS NO DIRECT CONTROL OVER MACHINE APPLICATION AND OPERATION. THE USER AND OPERATOR ARE RESPONSIBLE FOR CONFORMING WITH GOOD SAFETY PRACTICES.

This section provides the necessary information needed to understand control functions.

3.2 CONTROLS AND INDICATORS

NOTE: All machines are equipped with control consoles that use sym-

bols to indicate control functions. On ANSI machines refer to decal located on the control box guard in front of the control box or by the ground controls for these symbols and the corresponding functions.

NOTE: The indicator panels use different shaped symbols to alert the

operator to different types of operational situations that could arise. The meaning of those symbols are explained below.

Indicates a potentially hazardous situation, which if not corrected, could result in serious injury or death. This indicator will be red.

Indicates an abnormal operating condition, which if not corrected, may result in machine interruption or damage. This indicator will be yellow.

Indicates important information regarding the o perating condition, i.e. procedures essential for safe operation. This indicator will be green with the exception of the capacity indicator which will be green or yellow depending upon platform position.

TO AVOID SERIOUS INJURY, DO NOT OPERATE MACHINE IF ANY CONTROL LEVERS OR TOGGLE SWITCHES CONTROLLING PLATFORM MOVEMENT DO NOT RETURN TO THE OFF OR NEUTRAL POSITION WHEN RELEASED.

1. Drive Speed/Torque Select

The forward position gives maximum drive speed. The back position gives maximum torque for rough terrain and climbing grades. The center position allows the machine to be driven as quietly as possible.

2. Steer Select

The action of the steering system is operator selectable. The center switch position gives conventional front wheel steering with the rear wheels unaffected. This is for normal driving at maximum speeds. The forward position is for “crab” steering. When in this mode both front and rear axles steer in the same direction, which allows the chassis to move sideways as it goes forward. This can be used for positioning the machine in aisle ways or close to buildings. The back switch position is for “coordinated” steering. In this mode the front and rear axles steer in the opposite directions to produce the tightest turning circle for maneuvering in confined areas.

SECTION 4. MACHINE OPERATION

SECTION 4 - MACHINE OPERATION

4.1 DESCRIPTION

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

The primary operator control console is in the platform. From this control console, the operator can drive and steer the machine in both forward and reverse directions. The operator can raise or lower the boom or swing the boom to the left or right. Standard boom swing is 360 degree continuous rotation. The machine has a Ground Control Console which will override the Platform Control Console. Ground Controls operate Boom Lift and Swing, and are to be used in an emergency to lower the platform to the ground should the operator in the platform be unable to do so.

4.2 BOOM OPERATING CHARACTERISTICS AND LIMITATIONS

Capacities

Raising boom above horizontal with or without any load in platform, is based on the following criteria:

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

2. Axles are fully extended.

3. Jib is centered and lock pin is engaged.

4. Load is within manufacturer’s rated capacity.

5. All machine systems are functioning properly.

6. Proper tire pressure.

7. Machine is as originally equipped from JLG.

3121618 – JLG Lift – 4-1

SECTION 4 - MACHINE OPERATION

Controlled Arc

When the Boom Control Select switch is in the automatic mode, the Boom Control System automatically controls lift and telescope when the lift function is selected to move the platform through a predetermined arc, equivalent to the percentage of extension. (i.e. If you start at 70% boom extension, you will end up at approximately 70% boom extension no matter where you stop in the arc). This means that when lifting down, telescope in

will function automatically, or when lifting up, telescope out will function automatically.

When the Boom Control Switch is in the manual mode, lift and telescope functions are independent functions controlled by the operator.

4-2 – JLG Lift – 3121618

SECTION 4 - MACHINE OPERATION

Envelope Tracking

When the platform approaches the edges of the operating envelope all machine functions are slowed down except jib and platform functions, telescope in or out at the rearward edge and telescope in or out on the forward edge are slowed down automatically by the boom control system to reduce machine motions.

NOTE: Boom Control System in Automatic Mode: When the boom is

completely elevated along the edge of the backward stability region and the telescope in function is activated, lift down will automatically function until the boom is away from the edge of the backward stability region.

Boom Control System in Manual Mode: The boom will stop when the end of the envelope is reached and the operator must activate lift and/or telescope in the proper direction to bring the boom back into the envelope.

Controlled Angle

The control system automatically maintains a constant elevated boom angle when swinging the turntable. If the boom angle is at 30 degrees and swing only is activated the control system shall add lift to maintain the relative boom angle at 30 degrees.

Swing Speed Proportioning

The Boom Control System sensors sense the distance the platform is extended from the turntable, allowing higher swing speeds with the boom retracted and gradually slower swing speeds as the boom is extended.

3121618 – JLG Lift – 4-3

SECTION 4 - MACHINE OPERATION

Stability

Machine stability is based on two (2) conditions which are called FORWARD and BACKWARD stability. The machine’s position of least FORWARD stability is shown in Figure 4-1., and its position of least BACKWARD stability is shown in Figure 4-2.

TO AVOID FORWARD OR BACKWARD TIPPING, DO NOT OVERLOAD MACHINE OR OPERATE THE MACHINE ON AN OUT-OF-LEVEL SURFACE.

4.3 CAPACITY SELECT

The Boom Control System allows the operator to select operation in a 500 lb. (227 kg for ANSI markets and 230 kg for CE and Australia markets) capacity restriction envelope or a 1000 lb. (454 kg for ANSI markets and 450 kg for CE and Australia markets) capacity restriction envelope. The operator selects the desired capacity restriction by positioning the Capacity Select switch on the platform console. The Capacity Indicator shows the capacity selected, and both capacity lights will flash and an alarm sound if the platform is out of the selected capacity range.

NOTE: Operation in the 1000 lb. (454 kg for ANSI markets and 450 kg for

CE and Australia markets) envelope requires the jib to be fully retracted.

SECTION 4 - MACHINE OPERATION

Fuel Reserve / Shut-Off System

NOTE: Reference the Service and Maintenance Manual along with a

qualified JLG Mechanic to verify your machine setup.

The Fuel Shutoff System monitors the fuel in the tank and senses when the fuel level is getting low. The JLG Control System automatically shuts the engine down before the fuel tank is emptied unless the machine is set up for Engine Restart.

If fuel level reaches the Low Fuel range the ¼ tank indicator will flash once a second and there will be approximately 5 minutes of engine run time left. If the system is in this condition and automatically shuts down the engine, or the engine is manually shut down before the 5 minute run time is complete, the ¼ tank indicator will flash 10 times a second and the engine will react according to machine setup. Setup options are as follows:

• Engine One Restart - When the engine shuts down, the operator will be permitted to cycle power and restart the engine once with approximately 2 minutes of run time. After the 2 minute run time is complete or if the engine is shut down by the operator prior to the completion of the 2 minute run time, it cannot be restarted until fuel is added to the tank.

• Engine Restart - When the engine shuts down, the operator will be permitted to cycle power and restart the engine for approximately 2 minutes of run time. After the 2 minutes of run time is complete, the operator may cycle power and restart the engine for an additional 2 minutes of run time. The operator can repeat this process until there is no more fuel available.

CONTACT A QUALIFIED JLG MECHANIC IF THE MACHINE NEEDS RESTARTED AFTER NO MORE FUEL IS AVAILABLE.

• Engine Stop - The engine will shut down. No restarts will be permitted until fuel is added to the tank.

4.8 PLATFORM

Platform Level Adjustment

NOTE: When the Boom Control Select Switch is in the Manual mode,

Platform leveling only functions during Main Lift operation. When the Boom Control Select Switch is in the Automatic mode, Platform Leveling is active during all functions except during telescope operation. Also, when in the Manual mode, the Controlled Arc and Controlled Angle systems are not active.

During normal operation of the machine, the platform will automatically maintain it’s position. To manually Level Up or Down - Position the Platform/ Level control switch Up or Down and hold until the desired platform position is obtained.

Platform Rotation

To rotate the platform to the left or right, use the Platform Rotate control switch to select the direction and hold until desired position is reached.

4.9 BOOM

A RED TILT WARNING LIGHT IS LOCATED ON THE CONTROL CONSOLE WHICH LIGHTS WHEN THE CHASSIS IS ON AN EXCESSIVE SLOPE. DO NOT SWING OR RAISE BOOM ABOVE HORIZONTAL WHEN LIGHT IS LIT.

DO NOT DEPEND ON TILT ALARM AS A LEVEL INDICATOR FOR THE CHASSIS. TILT ALARM INDICATES CHASSIS IS ON AN EXCESSIVE SLOPE (5 DEGREE OR GREATER). CHASSIS MUST BE LEVEL BEFORE SWINGING, OR RAISING BOOM ABOVE HORIZONTAL OR DRIVING WITH THE BOOM ELEVATED.

TO AVOID TIP OVER IF RED TILT WARNING LIGHT LIGHTS WHEN BOOM IS RAISED ABOVE HORIZONTAL, LOWER PLATFORM TO GROUND LEVEL. THEN REPOSITION MACHINE SO THAT CHASSIS IS LEVEL BEFORE RAISING BOOM.
