SECTION 3 - USER RESPONSIBILITIES AND MACHINE CONTROL
3-6 – JLG Sizzor – 3120761
NOTE: The High Drive Speed switch will cut-out when the
platform is raised above the stowed position, return-
ing drive speed to low until the platform is lowered
completely.
DO NOT OPERATE MACHINE IF HIGH DRIVE SPEED OPERATES
WHEN PLATFORM IS RAISED ABOVE THE STOWED POSITION.
8. Lift Switch - The lift switch, when used in conjunc-
tion with the joystick, provides for raising and lower-
ing the platform. Lift is activated by pressing the lift
switch and moving the joystick forward (lift up) or
backward (lift down). Lift up speed is determined by
the distance the joystick is moved forward. Lift down
speed is non-adjustable, and lift down is attained by
moving the joystick fully backward. The lift switch is
part of the enable circuit, which provides power to
the joystick and the lift function for 3 seconds when
the lift switch is pressed. If the joystick is not acti-
vated within 3 seconds, the lift switch must be
pressed again before activating the joystick. When
the joystick is returned to the center off position, the
operator has 3 seconds to re-activate the joystick or
select another function before power is removed by
the enable circuit. Do not try to operate the drive, lift,
and powered deck extension functions simulta-
neously. If the drive, lift, and powered deck exten-
sion functions are selected simultaneously, no
function will operate. If this occurs, pause, then
press only one of the function switches to activate
the function.
DO NOT LIFT DOWN WITHOUT COMPLETELY RETRACTING THE
PLATFORM EXTENSION.
IMPORTANT
DO NOT ATTEMPT TO OPERATE THE LIFT AND DRIVE FUNC-
TIONS AT THE SAME TIME; NO FUNCTION WILL OPERATE AND IT
WILL BE NECESSARY TO RE-SELECT A SINGLE FUNCTION.
WHEN OPERATING LIFT DOWN MOVE THE JOYSTICK TO THE
FULL DOWN (FULLY BACKWARD) POSITION.
9. Positive Traction (Posi-Trac) Switch - This switch,
when pressed, activates a solenoid on the main con-
trol valve, forcing oil through a flow divider in the
drive circuit, maintaining hydraulic oil flow to both
drive motors for improved traction. The positive trac-
tion (Posi-trac) switch activates the positive traction
solenoid for a preset time when the positive traction
(Posi-trac) switch is pressed. Positive traction is
automatically de-activated after the preset time is
out. This function will only operate when the drive
function is activated.
10. Powered Deck Extension Switch (If Equipped -
Models 2033E3, 2046E3, 2646E3, and 2658E3
Only.) - If the machine is equipped with either the 4
ft. (1.2 m) or 6 ft. (1.8 m) hydraulically-powered deck
extension, this switch is used in conjunction with the
joystick to provide extension or retraction of the
powered deck extension. Powered deck extension
or retraction is activated by pressing the powered
deck extension switch and moving the joystick for-
ward (EXTEND) or backward (RETRACT). The pow-
ered deck extension switch is part of the enable
circuit, which provides power to the joystick and the
powered deck extension function for 3 seconds
when the powered deck extension switch is
pressed. If the joystick is not activated within 3 sec-
onds, the powered deck extension switch must be
pressed again before activating the joystick. When
the joystick is returned to the center off position, the
operator has 3 seconds to re-activate the joystick or
select another function before power is removed by
the enable circuit. Do not try to operate the powered
deck extension, drive, and lift functions simulta-
neously. If the powered deck extension, drive, and
lift functions are selected simultaneously, no func-
tion will operate. If this occurs, pause, then press
only one of the function switches to activate the
function.
11. Tilt Alarm Warning Horn - The Tilt Alarm Warning
Horn is activated by the Tilt Alarm Switch when the
chassis is on a severe slope (over 1.5° or 2.0°
depending on which tilt the machine is equipped
with). When the machine is equipped with a pow-
ered deck extension, the horn is activated when the
deck extension is being extended or retracted.
IF TILT ALARM IS ON WHEN PLATFORM IS RAISED, LOWER
PLATFORM COMPLETELY, THEN REPOSITION MACHINE SO
THAT IT IS LEVEL BEFORE RAISING PLATFORM.
12. Tilt Alarm Warning Light - A red warning light on
the membrane switch panel that illuminates when
the chassis is on a severe slope (over 1.5° or 2.0°
depending on which tilt the machine is equipped
with).
13. Horn (If Equipped) - This push-button switch, when
activated, permits the operator to warn jobsite per-
sonnel when the machine is operating in the area.
14. Battery Discharge Indicator (If Equipped) - The
battery discharge indicator is a gauge that provides
a visual indication of the condition of the batteries.
