SECTION 3 - MACHINE CONTROLS AND INDICATORS
3. System Distress Indicator
The system distress indicator lights to signify
an abnormal condition for the generator
engine (high oil temperature or low oil pressure) or, on all electric machines, an electrical
system fault.
The four likely causes of a system fault are:
a. The seven second enable time has been allowed to
lapse or a function was selected before depressing the
footswitch. The system reads this condition as a fault,
just as it would if the footswitch were jammed in the
depressed position or a function switch were stuck in
the on position. Re-depress the footswitch to power the
controls and extinguish the light.
b. The maximum power limit has been reached and the
machine is not moving. This could happen when the
machine is stuck or when attempting to travel over
rough terrain or on steep grades which exceed the
rated gradeability of the machine. This condition is
comparable to stalling the engine by asking it to provide more power than it was designed to do.
c. The batteries are nearly depleted, and should be
charged very soon to prevent having the machine stop
at an inconvenient place.
d. There is some other fault in one of the circuits. If so
determine the cause by counting the flash code, a number of flashes followed by a pause followed by another
number of flashes, and refer to the service manual.
NOTE:The engine will automatically shut down under the following
conditions:
High Engine Oil Temperature
Low Engine Oil Pressure
Engine Overspeed
Generator Overvoltage
4. Drive Orientation Indicator
When the boom is swung beyond the
rear drive tires or further in either direction, the Drive Orientation indicator will
illuminate when the drive function is
selected. This is a signal for the operator to verify that
the drive control is being operated in the proper direction (i.e. controls reversed situations).
3-14– JLG Lift –3121644
5. Posi-Track Indicator
SECTION 3 - MACHINE CONTROLS AND INDICATORS
This indicator lights to show that positraction is operating.
6. Enable Indicator/Footswitch
To operate any function, the footswitch
must be depressed and the function
selected within seven seconds. The enable
indicator shows that the controls are
enabled. If a function is not selected within seven seconds,
or if a seven second lapse between ending one function and
beginning the next function, the enable light will go out and
the footswitch must be released and depressed again to
enable the controls.
Releasing the footswitch removes power from all controls
and applies the drive brakes.
TO AVOID SERIOUS INJURY, DO NOT REMOVE, MODIFY OR DISABLE THE FOOTSWITCH
BY BLOCKING OR ANY OTHER MEANS.
FOOTSWITCH MUST BE ADJUSTED IF FUNCTIONS ACTIVATE WHEN SWITCH ONLY
OPERATES WITHIN LAST 1/4" OF TRAVEL, TOP OR BOTTOM.
7. Low Battery Indicator
Indicates the batteries are low and need to
be charged.

8. Soft Touch Indicator (If Equipped)
When illuminated (Yellow) the Soft Touch
bumper is against an object. All controls
are disabled until the override button is
pushed, at which time controls are active in
the Creep mode.
9. Creep Speed Indicator
When the Function Speed Control is
turned to the creep position, the indicator
acts as a reminder that all functions are set
to the slowest speed.

4.1DESCRIPTION
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 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 non-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 Upper and Lower 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.

6.4BATTERY MAINTENANCE AND CHARGING
Battery Maintenance, Quarterly
1. Open battery compartment cover to allow access to battery
terminals and vent caps.
WHEN ADDING WATER TO BATTERIES, ADD WATER UNTIL ELECTROLYTE COVERS
PLATES. DO NOT CHARGE BATTERIES UNLESS ELECTROLYTE COVERS THE PLATES.
NOTE:When adding distilled water to batteries, non-metallic contain-
ers and/or funnels must be used.
To avoid electrolyte overflow, add distilled water to batteries
after charging.
When adding water to the battery, fill only to level indicated or 3/
8" above separators.
2. Remove all vent caps and inspect electrolyte level of each
cell. Electrolyte level should be to the ring approximately
one inch from top of battery. Fill batteries with distilled
water only. Replace and secure all vent caps.
3. Remove battery cables from each battery post one at a time,
negative first. Clean cables with acid neutralizing solution
(e.g. baking soda and water or ammonia) and wire brush.
Replace cables and/or cable clamp bolts as required.
4. Clean battery post with wire brush then re-connect cable to
post. Coat non-contact surfaces with mineral grease or
petroleum jelly.
5. When all cables and terminal posts have been cleaned,
ensure all cables are properly positioned and do not get
pinched. Close battery compartment cover.
6. Start hydraulic system and ensure that it functions properly.

TO AVOID INJURY FROM AN EXPLOSION, DO NOT SMOKE OR ALLOW SPARKS OR A
FLAME NEAR BATTERY DURING SERVICING. ALWAYS WEAR EYE AND HAND PROTECTION WHEN SERVICING BATTERIES.
Battery Charging (On Board Charger)
1. For maximum battery life:
a. Avoid completely discharging the batteries.
b. Fully charge the batteries each day the machine is used.
c. Charge the batteries at available times between charg-
ing.
d. If applicable, be sure the battery fluid covers the battery
plates before charging, but to avoid overflow, do not
top off the fluid level until charging.
2. To charge the batteries, connect the charger to an appropriate volt source with a 15 amp minimum capacity.
3. The charge cycle is complete when the green 100% charge
light on the battery charger comes on.

6.5TIRES & WHEELS
Tire Inflation
The air pressure for pneumatic tires must be equal to the air pressure that is stenciled on the side of the JLG product or rim decal
for safe and proper operational characteristics.
Tire Damage
For pneumatic tires, JLG Industries, Inc. recommends that when any
cut, rip, or tear is discovered that exposes sidewall or tread area cords
in the tire, measures must be taken to remove the JLG product from
service immediately. Arrangements must be made for replacement
of the tire or tire assembly.
For polyurethane foam filled tires, JLG Industries, Inc. recommends
that when any of the following are discovered, measures must be
taken to remove the JLG product from service immediately and
arrangements must be made for replacement of the tire or tire
assembly.
• a smooth, even cut through the cord plies which exceeds 3
inches (7.5 cm) in total length
• any tears or rips (ragged edges) in the cord plies which
exceeds 1 inch (2.5 cm) in any direction
• any punctures which exceed 1 inch in diameter
• any damage to the bead area cords of the tire
If a tire is damaged but is within the above noted criteria, the tire
must be inspected on a daily basis to insure the damage has not
propagated beyond the allowable criteria.
Tire Replacement
JLG recommends a replacement tire be the same size, ply and brand
as originally installed on the machine. Please refer to the JLG Parts
Manual for the part number of the approved tires for a particular
machine model. If not using a JLG approved replacement tire, we
recommend that replacement tires have the following characteristics:
• Equal or greater ply/load rating and size of original
• Tire tread contact width equal or greater than original
• Wheel diameter, width, and offset dimensions equal to the
original
• Approved for the application by the tire manufacturer
(including inflation pressure and maximum tire load)
Unless specifically approved by JLG Industries Inc. do not replace a
foam filled or ballast filled tire assembly with a pneumatic tire. When
selecting and installing a replacement tire, ensure that all tires are
inflated to the pressure recommended by JLG. Due to size variations
between tire brands, both tires on the same axle should be the same.
