SECTION A. INTRODUCTION - MAINTENANCE SAFETY
PRECAUTIONS
A
GENERAL
C
This section contains the general safety precautions
which must be observed during maintenance of the aerial
platform. It is of utmost importance that maintenance personnel pay strict attention to these warnings and precautions to avoid possible injury to themselves or others, or
damage to the equipment. A maintenance program must
be followed to ensure that the machine is safe to operate.
MAINTENANCE
FAILURE TO COMPLY WITH SAFETY PRECAUTIONS LISTED IN
THIS SECTION MAY RESULT IN MACHINE DAMAGE, PERSONNEL
INJURY OR DEATH AND IS A SAFETY VIOLATION.
• REMOVE ALL RINGS, WATCHES AND JEWELRY
WHEN PERFORMING ANY MAINTENANCE.
MODIFICATION OF THE MACHINE WITHOUT CERTIFICATION BY
A RESPONSIBLE AUTHORITY THAT THE MACHINE IS AT LEAST
AS SAFE AS ORIGINALLY MANUFACTURED, IS A SAFETY VIOLATION.
• DO NOT WEAR LONG HAIR UNRESTRAINED, OR
LOOSE-FITTING CLOTHING AND NECKTIES WHICH
ARE APT TO BECOME CAUGHT ON OR ENTANGLED
IN EQUIPMENT.
The specific precautions to be observed during maintenance are inserted at the appropriate point in the manual.
These precautions are, for the most part, those that apply
when servicing hydraulic and larger machine component
parts.
• OBSERVE AND OBEY ALL WARNINGS AND CAUTIONS ON MACHINE AND IN SERVICEMANUAL.
Your safety, and that of others, is the first consideration
when engaging in the maintenance of equipment. Always
be conscious of weight. Never attempt to move heavy
parts without the aid of a mechanical device. Do not allow
heavy objects to rest in an unstable position. When raising
a portion of the equipment, ensure that adequate support
is provided.
• KEEP OIL, GREASE, WATER, ETC. WIPED FROM
STANDING SURFACES AND HAND HOLDS.
• NEVER WORK UNDER AN ELEVATED SIZZOR UNTIL
PLATFORM HAS BEEN SAFELY RESTRAINED FROM
ANY MOVEMENT BY BLOCKING OR OVERHEAD
SLING, OR BOOM SAFETY PROP HAS BEEN
ENGAGED.
• BEFORE MAKING ADJUSTMENTS, LUBRICATING OR
PERFORMING ANY OTHER MAINTENANCE, SHUT
OFF ALL POWER CONTROLS.
SINCE THE MACHINE MANUFACTURER HAS NO DIRECT CONTROL OVER THE FIELD INSPECTION AND MAINTENANCE,
SAFETY IN THIS AREA IS THE RESPONSIBILITY OF THE OWNER/
OPERATOR.
• BATTERY SHOULD ALWAYS BE DISCONNECTEDDURING REPLACEMENT OF ELECTRICAL COMPONENTS.
B
• KEEP ALL SUPPORT EQUIPMENT AND ATTACHMENTS STOWED IN THEIR PROPER PLACE.
HYDRAULIC SYSTEM SAFETY
It should be noted that the machines hydraulic systems
operate at extremely high, potentially dangerous pressures. Every effort should be made to relieve any system
pressure prior to disconnecting or removing any portion of
the system.

INTRODUCTION & OPERATION
1.2
USING THE ANALYZER
With the machine power on and the analyzer connected
properly, the analyzer will display the following:
NOTE: It is the responsibility of the owner/user/operator/lessor/lessee to read & understand this manual and the
machine Operators & Safety Manual and to prevent
overloading the platform. Do not operate a machine
with a disconnected or inoperative Load Sensing
System.
The JLG-designed Load Sensing System (LSS) measures
platform load. If the actual platform load exceeds the
selected Rated Load, the following will occur:
1. The Overload Visual Warning Indicator will flash at
the selected control position (platform or ground).
2. The Platform and Ground Alarms will sound 5 seconds On, and 2 seconds Off.
3. All normal movement will be prevented from the
platform control position (optional - ground control
functions may be prevented).
4. Further movement is permitted by:
a. Removing the excess platform load until actual
platform load is less than Rated Load.
b. By an authorized person at the ground control
position (optional - ground control functions
may be prevented).
THE LOAD SENSING SYSTEM MUST BE CALIBRATED WHEN ONE
OR MORE OF THE FOLLOWING CONDITIONS OCCUR:
a. LSS System initial installation
b. LSS Module replacement
c. LSS Sensor removal or replacement
d. Addition or removal of certain platform mounted
accessories. (Refer to Calibration in Section 2)
HELP:
PRESS ENTER
At this point, using the RIGHT and LEFT arrow keys, you
can move between the top level menu items. To select a
displayed menu item, press ENTER. To cancel a selected
menu item, press ESC.; then you will be able to scroll
using the right and left arrow keys to select a different
menu item.
If you press ENTER at the HELP: PRESS ENTER display
and there are no faults, the Analyzer will display EVERYTHING OK. In the event of a fault, the Analyzer will display
a Help Message.
e. Platform is removed, replaced, repaired or
shows evidence of impact.
If ENTER is pressed again, the Analyzer will display
LOGGED HELP, a record of the last 16 faults. Use the left
and right arrow keys to scroll through the fault log. To
return to the top level menu, press the ESC key twice.
THE LOAD SENSING SYSTEM REQUIRES PERIODIC FUNCTION
VERIFICATION NOT TO EXCEED 6 MONTHS FROM PREVIOUS
VERIFICATION. REFER TO TESTING & EVALUATION IN SECTION
2.
When a top level menu entry is selected, a new set of
menu items will be displayed.
Calibration of the Load Sensing System is performed by
connecting the JLG Analyzer (Analyzer Kit, JLG part no.
2901443). All calibration procedures are menu driven
through the use of the Analyzer.

JLG WORKSTATION IN THE SKY™
ACCESSORIES
Table 2-6. LSS Module Guidelines
The Load Sensing System must be configured for proper
operation with JLG Sky™ Accessories. Calibration of the
Load Sensing System can be performed with the Accessory mounted in the platform.
A platform-mounted accessory slightly reduces the
amount of load that can be carried before the vehicle
becomes overloaded. This extra load must be accounted
for to enable the accessory to be mounted during Calibration.
A De-Rating is provided for JLG Sky Accessories via decal
and/or the JLG Workstation in the SkyTM Accessory Manual. This De-Rating must be entered into the LSS Module’s ACC’Y Personality to cause the system to accurately
indicate overload (by the De-Rating factor).
PERSONALITY
SETTING
ACC’Y
300 lb (136 kg)
Procedurally, the Accessory should be mounted to the
platform and the LSS Module’s ACC’Y Personality should
be set using the guidelines above. Calibration should be
performed as outlined in this manual. During Testing &
Evaluation, it should be noted that the LSS will declare
Overload with less platform load (by the amount of the DeRating).
Example: Consider that of the Easi-Cladder™ with a DeRating of 300 lbs (136 kg) mounted on a 500RTS. Without
De-Rating, the Load Sensing System will declare on Overload at 2750 lb (1247 kg), which is 110% of its 2500 lb
(1134 kg) rated Load. When the De-Rating for Easi-Cladder™ is entered into the ACC’Y Personality, the LSS will
declare Overload 300 lb (136 kg) earlier (2450 lb or 1111
kg).

Procedure
1. Plug the JLG Analyzer into the LSS Module on the
LE, MRT and RTS or the Host Control System on the
ES and RT and enter the Access Level 1 Password.
Do not confuse the Host Control System and LSS
Module’s Analyzer Connections. Proceed to the
ACCESS LEVEL menu and enter the Access Level 1
Password (33271).
2. Park the vehicle on a level surface. The platform
should be fully stowed and level within ± 5° (both
directions).
Testing & Evaluation
Refer to the Troubleshooting section of this manual if the
Load Sensing System fails to meet these guidelines.
3. Configure the LSS Module for the proper model and
Desired Units. On LE, MRT and RTS, proceed to the
LSS Module’s MACHINE SETUP, MODEL sub-menu
and select “MODEL=4069LE, 3369LE, 500RTS, or
260MRT”. Press the RIGHT ARROW to view the
Units Selection. Select “UNITS=LBS” for platform
load measurement in Pounds, and “UNITS=KG” for
measurement in Kilograms.

PLUG THE JLG ANALYZER INTO THE MODULE’S CONNECTION
BENEATH THE DECKAND ENTER THE ACCESS LEVEL 1 PASSWORD (33271). UNDER MACHINE SETUP ENSURE THAT
MODEL=260MRT.
4. Remove everything except JLG Accessories from
the Platform. Empty the platform to allow the Load
Sensing System to record its weight during calibration. All tools, debris, and customer-installed devices
shall be removed. Permanently-fixed JLG Accessories shall remain and their contribution toward Rated
Load will be accounted for in the next step.
1. Plug the JLG Analyzer into the LSS Module (LE,
MRT and RTS) or the Host Control System (ES and
RT).
2. Park the vehicle on a level surface. The platform
should be fully stowed and level within ± 5° (both
directions).
3. Observe the Empty Platform Weight. Proceed to the
DIAGNOSTICS, PLTLOAD sub-menu and observe
the measured platform load. All tools, debris, and
customer-installed devices shall be removed during
evaluation. Ideally, the PLTLOAD should be zero but
can vary +15lbs (± 7kg). Further, the reading
should be stable and should not vary by more than
+2lbs (±1kg) (unless there is heavy influence from
wind or vibration).
4. Use the Technician’s Weight to Evaluate. The technician should enter the platform and record the PLTLOAD reading while standing in the center of the
platform, and then each corner. The average of the
readings should be the estimated weight of the technician. The range of the readings should be no more
than 40lbs (18kg) (max PLTLOAD reading – min PLTLOAD reading).
5. Configure the LSS Module for JLG Accessories. The
contribution of each permanently-fixed JLG Accessory toward Rated Load must be determined. JLG
Accessories are decaled with their effective contribution toward Rated Load. If this decal is missing, reference the appropriate manual for the JLG
Accessory. Once determined, the contributions of all
permanently-fixed JLG Accessories mounted in the
platform of the vehicle shall be added together and
entered in the Analyzer’s PERSONALITIES, ACC’Y
display (using the proper units).

equipped) and ensure that all controls are functional
and the Load Sensing System’s Overload Visual and
Audible Warnings are not active. Simulate an Overload by unplugging the Shear Pin Load Cell connected to J5 on the LSS Module. The Overload
Visual Warning should flash, and the Audible Warning (at Platform and Ground) should sound for 5
seconds On, and 2 seconds Off. With the engine
running (If equipped), all platform control should be
prevented. Cycle the Platform EMS to stop the
engine and then power-up again. The Overload
Visual and Audible Warning should continue. Install
the disconnected Shear Pin Load Cell back in J5 on
the LSS Module. The Overload Visual and Audible
Warnings should cease and normal control function
should return. Switch the vehicle’s keyswitch to
Ground Mode and repeat the above procedure. The
Overload Visual Warning at the Ground Controls
should flash, and the Audible Warning (at Platform
and Ground) should sound for 5 seconds On, 2 seconds Off. However, the controls should remain functional when using the engine (if the Host Controls
System’s MACHINE SETUP, LOAD is set to “2=CUTOUT PLT”. If set to “3=CUTOUT ALL”, then Ground
Controls will be prevented when using the platform).
Re-fit the Shear Pin Load Cell connector to J5 on the

4. Damage to the platform or arm structure has occurred or one of the components is
out-of-tolerance.Twists in the platform, for instance, will cause huge off-axis forces to
be applied to the Shear Pin Load Cells, disturbing their primary measurement axis
readings. If Lift Up / Down is noisy or not smooth, examine this issue thoroughly.
Resolution is to replace the damaged or faulty component. Watch for Shear Pin Load
Cell damage (yield) as a result of this difficulty.
5. One of the Shear Pin Load Cells is contaminated by debris or moisture. Examine
each sensor’s reading using the JLG Analyzer. Proceed to the DIAGNOSTICS, CELL
1-4, LOAD displays and determine if the readings are reasonable and stable (not
changing by more than +2lbs (±1kg) (without the influence of vibration or wind).
Lack of measurement stability is a key indication of contamination. Unplug the
appropriate connector (J5 is CELL 1, J6 is CELL 2, J7 is CELL 3, and J8 is CELL 4)
and inspect for dirt or moisture. Look carefully into the female connector on the sensor’s cordset for evidence of contamination. Debris should be brushed away with a
soft bristle brush (do not introduce any cleaners as they will leave conductive residue). Moisture should be allowed to evaporate or accelerated with a heat-gun (use
low heat and be carefully to not melt connector materials). Moisture intrusion into the
molded portion of the connector (capillary action into the wire bundle) or the Shear
Pin Load Cell itself will require replacement of the sensor.
6. One of the Shear Pin Load Cells has been mechanically damaged (yielded). Any
Shear Pin Load Cell that is physically deformed or has damage to one of the stainless steel covers should be replaced immediately. It is also possible to have invisible
mechanical damage resulting from an extreme overload (>4200lbs [>1900kg] for
1.25 in diam.; >5700 lbs or 2600 KG for 2 inch diam.). This can be detected by supporting the platform with an overhead crane and by removing the suspect sensor (no
weight resting on the Shear Pin Load Cell). Examine the sensor’s reading using the
JLG Analyzer. Proceed to the DIAGNOSTICS, CELL 1-4, LOAD displays and observe
whether the unloaded sensors read with +15lbs (±7kg) of zero (individually).
Replace sensors that read excessive force when physically unloaded.
7. The LSS Module is suspect. Interchange the Shear Pin Load Cell connections (J5J8) and observe the results via the JLG Analyzer. Proceed to the DIAGNOSTICS,
CELL 1-4, LOAD displays and observe the readings. If the problem seems to remain
with a particular sensor, carefully re-examine the issues above. If the problems
seems to remain with a particular LSS Module channel, substitute another module.

DESCRIPTION (RS)
The platform load sensing system is intended to prevent

Platform Load Sensing System Calibration
Procedure (RS)
1. If the Angle Sensor has not been calibrated refer to
the Angle Sensor Calibration Procedure first!
The pressure transducers, which are located at the barrel
end of the lift cylinder, (See Figure 6-1. and Figure 6-2.) are
intended to correlate hydraulic fluid pressure to the load
placed in the platform. The angle sensor, located at the
bottom of the arm stack to the rear of the 10RS, and
underneath the platform at the rear of the machine on the
6RS, (See Figure 6-3.) is intended to correlate machine
elevation with hydraulic fluid pressure as measured by the
pressure transducers.
2. Ensure the batteries are fully charged and the
hydraulic fluid level is acceptable.
3. Park the vehicle on a level surface. The platform
should be fully stowed and level within +/- 0.5
degrees (both directions).
4. Ensure the temperature is greater than 32 degrees
Fahrenheit.
5. Place weight corresponding to 110% of the
machines rated load in the center of the platform.
Secure the weight to the platform. See the chart
below to determine the correct weight for calibration
on each machine.
NOTE: JLG specifications require that this procedure be
performed every 500 machine hours or 6 months,
whichever occurs first. Calibrating the platform load
sensing system regularly is essential to safe machine
operation. Continuing to operate a machine without
calibrating at the recommended specifications could
compromise machine stability resulting in a
machine tip-over.
