SECTION A. INTRODUCTION - MAINTENANCE SAFETY

PRECAUTIONS

AGENERAL

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.

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.

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.

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.

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.

CMAINTENANCE

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.

• DO NOT WEAR LONG HAIR UNRESTRAINED, OR LOOSE-FITTING CLOTHING AND NECKTIES WHICH ARE APT TO BECOME CAUGHT ON OR ENTANGLED IN EQUIPMENT.

• OBSERVE AND OBEY ALL WARNINGS AND CAUTIONS ON MACHINE AND IN SERVICEMANUAL.

• 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.

•BATTERY SHOULD ALWAYS BE DISCONNECTEDDURING REPLACEMENT OF ELECTRICAL COMPONENTS.

• KEEP ALL SUPPORT EQUIPMENT AND ATTACH-

B 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.

MENTS STOWED IN THEIR PROPER PLACE.

• USE ONLY APPROVED, NONFLAMMABLE CLEANING SOLVENTS.

SECTION 1 - ANALYZER OPERATION - ALL

SECTION 1. ANALYZER OPERATION - ALL

NOTE: This manual is intended as a supplement to the indi-

vidual machine’s Operators and Safety Manual.

1.1 INTRODUCTION & OPERATION

NOTE: It is the responsibility of the owner/user/operator/les-

sor/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)

e. Platform is removed, replaced, repaired or

shows evidence of impact.

THE LOAD SENSING SYSTEM REQUIRES PERIODIC FUNCTION VERIFICATION NOT TO EXCEED 6 MONTHS FROM PREVIOUS VERIFICATION. REFER TO TESTING & EVALUATION IN SECTION

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.

1.2 USING THE ANALYZER

With the machine power on and the analyzer connected properly, the analyzer will display the following:

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 EVERY-

THING OK. In the event of a fault, the Analyzer will display a Help Message.

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.

When a top level menu entry is selected, a new set of menu items will be displayed.

Pressing ENTER while viewing any of the above menu entries will display additional sub-menus. Typically, the sub-menu is where parameter information is displayed or changed. You may only view Personality settings while in Access Level 2. Access Level 1 is required to change Personality settings and calibrate.

SECTION 1 - ANALYZER OPERATION - ALL

The ESC key may be used to leave a sub-menu at any time.

1.3 CHANGING THE ACCESS LEVEL OF THE HAND HELD ANALYZER

When the analyzer is first connected, you will be in access level 2 which enables you to only view most settings which cannot be changed until you enter a password to advance to a lower level. This ensures that a setting cannot be accidentally altered. To change the access level, the correct password must be entered. To enter the password, scroll to the ACCESS LEVEL menu. For example:

Once the correct password is displayed, press ENTER. The access level should display the following, if the password was entered correctly:

MENU: ACCESS LEVEL 1

Repeat the above steps if the correct access level is not displayed or you can not adjust the personality settings.

MENU: ACCESS LEVEL 2

Press ENTER to select the ACCESS LEVEL menu.

Using the UP or DOWN arrow keys, enter the first digit of the password, 3.

Then using the RIGHT arrow key, position the cursor to the right one space to enter the second digit of the password.

Use the UP or DOWN arrow key to enter the second digit of the password which is 33271.

SECTION 2 - OPERATION - (LE, MRT, RTS)

2.7 JLG WORKSTATION IN THE SKY™ ACCESSORIES

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 Sky ual. 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).

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).

Accessory Man-

Table 2-6. LSS Module Guidelines

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).
