7. Drive Speed/Torque Select
Drive Speed/Torque Select is a three position switch The forward position gives maximum drive speed by shifting the drive motors to minimum the displacement and giv­ing high engine when drive controller is moved. The back position gives maximum torque for rough terrain and climbing grades by shifting the wheel motors to maximum displacement and giving high engine speed when the drive controller is moved. The center position allows the machine to be driven as quietly as possible by leaving the engine at mid speed and the drive motors in minimum displacement or fastest speed.
8. Platform Rotate
The Swing control switch provides 360 degrees continu­ous turntable rotation when positioned to LEFT or RIGHT.
ONLY USE THE PLATFORM LEVELING OVERRIDE FUNCTION FOR SLIGHT LEVELING OF THE PLATFORM. INCORRECT USE COULD CAUSE THE LOAD/OCCUPANT TO SHIFT OR FALL. FAILURE TO DO SO COULD RESULT IN DEATH OR SERIOUS INJURY.

The ARTICULATING control switch provides raising and lowering of the jib when positioned to UP or DOWN.
11. Fuel Select (Dual Fuel Engine Only) (If Equipped)
Gasoline or liquid propane fuel may be selected by mov­ing the switch to the appropriate position. It is unneces­sary to purge the fuel system before switching fuels, so there is no waiting period when switching fuels while the engine is running.
3-12 – JLG Lift – 3121295
12. Work Lights. (If Equipped)
The switch, on the light, operates work lights if the machine is so equipped. The power/emergency stop switch must be on, (mushroom button out) but ignition switch does not have to be on to operate the lights, so care must be taken to avoid draining the battery if left unattended. The master switch and / or the ignition switch at the ground control will turn off power to all lights.
13. Steer Select. (If Equipped)
When equipped with four wheel steering, 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 the best position 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 against 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. A decal located at top of switch, instructs the desired wheel maneuver with the switch position.
SECTION 3 - MACHINE CONTROLS AND INDICATORS
To re-synchronize the front and rear axles, activate the steer switch (thumb rocker) until all steer cylinders are at the end of their stroke. This can be done in either crab or coordinated mode.
14. Auxiliary Power
When pushed forward, the switch energizes the starter motor to start the engine.
When pushed back, it energizes the electrically oper­ated hydraulic pump, when actuated. (Switch must be held ON for duration of auxiliary pump use.)
The auxiliary pump functions to provide sufficient oil flow to operate the basic machine functions should the main pump or engine fail. The auxiliary pump will operate tower boom lift, tower telescope, main boom lift, main telescope and swing.
3121295 – JLG Lift – 3-13
SECTION 3 - MACHINE CONTROLS AND INDICATORS
15. Tow e r L i f t
The three position center-off toggle switch provides for raising and lowering of the tower boom when positioned to “UP” or “DOWN”.
16. Drive Orientation Override
When the boom is swung over the rear tires or further in either direction, the Drive Orientation indicator will illumi­nate when the drive function is selected. Push and release the switch, and within 3 seconds move the Drive/Steer control to activate drive or steer. Before driv­ing, locate the black/white orientation arrows on both the chassis and the platform controls and match the control direction arrow to the intended chassis direction.
17. Soft Touch Override Switch (If equipped)
This switch enables the functions that were cut out by the Soft Touch system to operate again at creep speed, allowing the operator to move the platform away from the obstacle that caused the shutdown situation.
18. Soft Touch Indicator (If Equipped)
Indicates the Soft Touch bumper is against an object. All controls are cut out until the override button is pushed, at which time controls are active in the Creep Mode.

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 primary operator control station is 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 or lower the upper or lower boom or swing the boom to the left or right. Standard boom swing is 360 degree 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 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. The Ground Control is also to be used in Pre-Start Inspection.

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 positions which are called FORWARD STABILITY and BACKWARD STABILITY. The machine position of least forward stability is shown in Figure 4-1. and its positions of least backward stability is shown in Figure 4-2. and Figure 4-3.

SECTION 4 - MACHINE OPERATION

4.10 LIFTING AND TIE DOWN

When transporting machine, boom must be in the stowed position mode, (booms lowered and retracted) with turntable lock pin engaged, and machine securely tied down to truck or trailer deck. Six tie down eyes are provided in the frame slab, one at each corner of the machine and 2 holes at the center of the frame. (See Figure 4-5., Machine Tie Down)
If it becomes necessary to lift the machine using an over­head or mobile crane, it is very important that the turntable lock pin is engaged, lifting devices are attached only to the designated lifting eyes, and spreader bars are to be used to prevent damage to the machine. (See Figure 4-6., Lifting Chart for gross machine weights.)
NOTE: When transporting machine over rough terrain or long dis-
tance, the boom needs to be chocked and strapped. This prevents the boom from bouncing up causing possible damage.
NOTE: Crane and lifting devices, chains, slings, etc., must be
capable of handling the gross machine weight.
NOTE: Lifting eyes are provided at the front and rear in the frame
slab. Each of the four chains or slings used for lifting machine must be adjusted individually so machine remains level when elevated.
SECURE TURNTABLE WITH TURNTABLE LOCK BEFORE TRAVELING LONG DISTANCES OR HAULING MACHINE ON TRUCK/TRAILER.
