SECTION A. INTRODUCTION - MAINTENANCE SAFETY
PRECAUTIONS
A GENERAL
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 VIOLA-
TION.
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 RESPONSIBILITY OF THE OWNER/OPERATOR.
feed lines to system components can then be disconnected with minimal fluid loss.
C 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.
•NO SMOKING IS MANDATORY. NEVER REFUEL DURING ELECTRICAL STORMS. ENSURE THAT FUEL CAP IS CLOSED AND SECURE AT ALL OTHER TIMES.
•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.
•USE CAUTION WHEN CHECKING A HOT, PRESSURIZED COOLANT SYSTEM.
•NEVER WORK UNDER AN ELEVATED BOOM UNTIL BOOM 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.
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.
Relieve system pressure by cycling the applicable control several times with the engine stopped and ignition on, to direct any line pressure back into the reservoir. Pressure
•KEEP ALL SUPPORT EQUIPMENT AND ATTACHMENTS STOWED IN THEIR PROPER PLACE.
•USE ONLY APPROVED, NONFLAMMABLE CLEANING SOLVENTS.

NOTE: Hydraulic oils must have anti-wear qualities at least to API Service Classification GL-3, and sufficient chemical stability for mobile hydraulic system service. JLG Industries recommends Mobilfluid 424 hydraulic oil, which has an SAE viscosity index of 152.
NOTE: When temperatures remain consistently below -7 degrees C. (20 degrees F), JLG Industries recommends the use of Mobil DTE13.
NOTE: Aside from JLG recommendations, it is not advisable to mix oils of different brands or types, as they may not contain the same required additives or be of comparable viscosities. If use of hydraulic oil other than Mobilfluid 424 is desired, contact JLG Industries for proper recommendations.

2.2SERVICE AND GUIDELINES
General
The following information is provided to assist you in the use and application of servicing and maintenance procedures contained in this book.
Safety and Workmanship
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.
MAKE SURE THAT PERSONNEL ARE CLEAR OF CHASSIS AT ALL TIMES WHEN JACKS ARE EXTENDED.
JACKS RETRACT AUTOMATICALLY, LOWERING THE CHASSIS.
THE JACKS ARE TO BE USED FOR EXTENDING AND RETRACTING THE AXLES. THEY ARE NOT TO BE USED AS A MAINTE-
NANCE TOOL.
The jacks (if equipped) provided for extending and retracting the axles are not to be used as a maintenance tool. When performing maintenance on the machine which requires lifting, use adequate hydraulic jacks for lifting the machine, not the axle jacks.
Cleanliness
1.The most important single item in preserving the long service life of a machine is to keep dirt and foreign materials out of the vital components. Precautions have been taken to safeguard against this. Shields, covers, seals, and filters are provided to keep air, fuel, and oil supplies clean; however, these items must be maintained on a scheduled basis in order to function properly.
2.At any time when air, fuel, or oil lines are disconnected, clear adjacent areas as well as the openings and fittings themselves. As soon as a line or component is disconnected, cap or cover all openings to prevent entry of foreign matter.
3.Clean and inspect all parts during servicing or maintenance, and assure that all passages and openings are unobstructed. Cover all parts to keep them clean. Be sure all parts are clean before they are installed. New parts should remain in their containers until they are ready to be used.

SECTION 2 - GENERAL
Components Removal and Installation
1.Use adjustable lifting devices, whenever possible, if mechanical assistance is required. All slings (chains, cables, etc.) should be parallel to each other and as near perpendicular as possible to top of part being lifted.
2.Should it be necessary to remove a component on an angle, keep in mind that the capacity of an eyebolt or similar bracket lessens, as the angle between the supporting structure and the component becomes less than 90 degrees.
3.If a part resists removal, check to see whether all nuts, bolts, cables, brackets, wiring, etc., have been removed and that no adjacent parts are interfering.
Component Disassembly and Reassembly
When disassembling or reassembling a component, complete the procedural steps in sequence. Do not partially disassemble or assemble one part, then start on another. Always recheck your work to assure that nothing has been overlooked. Do not make any adjustments, other than those recommended, without obtaining proper approval.
Pressure-Fit Parts
When assembling pressure-fit parts, use an anti-seize or molybdenum disulfide base compound to lubricate the mating surface.
Bearings
1.When a bearing is removed, cover it to keep out dirt and abrasives. Clean bearings in nonflammable cleaning solvent and allow to drip dry. Compressed air can be used but do not spin the bearing.
2.Discard bearings if the races and balls (or rollers) are pitted, scored, or burned.
3.If bearing is found to be serviceable, apply a light coat of oil and wrap it in clean (waxed) paper. Do not unwrap reusable or new bearings until they are ready to install.
4.Lubricate new or used serviceable bearings before installation. When pressing a bearing into a retainer or bore, apply pressure to the outer race. If the bearing is to be installed on a shaft, apply pressure to the inner race.
Gaskets
Check that holes in gaskets align with openings in the mating parts. If it becomes necessary to hand-fabricate a gasket, use gasket material or stock of equivalent material and thickness. Be sure to cut holes in the right location, as blank gaskets can cause serious system damage.
Bolt Usage and Torque Application
1.Use bolts of proper length. A bolt which is too long will bottom before the head is tight against its related part. If a bolt is too short, there will not be enough thread area to engage and hold the part properly. When replacing bolts, use only those having the same specifications of the original, or one which is equivalent.
2.Unless specific torque requirements are given within the text, standard torque values should be used on heat-treated bolts, studs, and steel nuts, in accordance with recommended shop practices. (See Torque Chart Section 1.)
Hydraulic Lines and Electrical Wiring
Clearly mark or tag hydraulic lines and electrical wiring, as well as their receptacles, when disconnecting or removing them from the unit. This will assure that they are correctly reinstalled.
Hydraulic System
1.Keep the system clean. If evidence of metal or rubber particles are found in the hydraulic system, drain and flush the entire system.
2.Disassemble and reassemble parts on clean work surface. Clean all metal parts with non-flammable cleaning solvent. Lubricate components, as required, to aid assembly.
Lubrication
Service applicable components with the amount, type, and grade of lubricant recommended in this manual, at the specified intervals. When recommended lubricants are not available, consult your local supplier for an equivalent that meets or exceeds the specifications listed.
Battery
Clean battery, using a non-metallic brush and a solution of baking soda and water. Rinse with clean water. After cleaning, thoroughly dry battery and coat terminals with an anti corrosion compound.
Lubrication and Servicing
Components and assemblies requiring lubrication and servicing are shown in the Lubrication Chart in Section 1.

SECTION 2 - GENERAL
2.3 LUBRICATION AND INFORMATION
Hydraulic System
1.The primary enemy of a hydraulic system is contamination. Contaminants enter the system by various means, e.g., using inadequate hydraulic oil, allowing moisture, grease, filings, sealing components, sand, etc., to enter when performing maintenance, or by permitting the pump to cavitate due to insufficient system warm-up or leaks in the pump supply (suction) lines.
2.The design and manufacturing tolerances of the component working parts are very close, therefore, even the smallest amount of dirt or foreign matter entering a system can cause wear or damage to the components and generally results in faulty operation. Every precaution must be taken to keep hydraulic oil clean, including reserve oil in storage. Hydraulic system filters should be checked, cleaned, and/or replaced as necessary, at the specified intervals required in the Lubrication Chart in Section 1. Always examine filters for evidence of metal particles.
3.Cloudy oils indicate a high moisture content which permits organic growth, resulting in oxidation or corrosion. If this condition occurs, the system must be drained, flushed, and refilled with clean oil.
4.It is not advisable to mix oils of different brands or types, as they may not contain the same required additives or be of comparable viscosities. Good grade mineral oils, with viscosities suited to the ambient temperatures in which the machine is operating, are recommended for use.
NOTE: Metal particles may appear in the oil or filters of new machines due to the wear-in of meshing components.
Hydraulic Oil
1.Refer to Section 1 for recommendations for viscosity ranges.
2.JLG recommends Mobilfluid 424 hydraulic oil, which has an SAE viscosity of 10W-30 and a viscosity index of 152.
NOTE: Start-up of hydraulic system with oil temperatures below -15 degrees F (-26 degrees C) is not recommended. If it is necessary to start the system in a sub-zero environment, it will be necessary to heat the oil with a low density, 100VAC heater to a minimum temperature of -15 degrees F (-26 degrees C).
3.The only exception to the above is to drain and fill the system with Mobil DTE 13 oil or its equivalent. This will allow start up at temperatures down to -20 degrees F (-29 degrees C). However, use of this oil will give poor performance at temperatures above 120 degrees F (49 degrees C). Systems using DTE 13 oil should not be operated at temperatures above 200 degrees F (94 degrees C) under any condition.
Changing Hydraulic Oil
1.Use of any of the recommended crankcase or hydraulic oils eliminates the need for changing the oil on a regular basis. However, filter elements must be changed after the first 50 hours of operation and every 300 hours thereafter. If it is necessary to change the oil, use only those oils meeting or exceeding the specifications appearing in this manual. If unable to obtain the same type of oil supplied with the machine, consult local supplier for assistance in selecting the proper equivalent. Avoid mixing petroleum and synthetic base oils. JLG Industries recommends changing the hydraulic oil annually.
2.Use every precaution to keep the hydraulic oil clean. If the oil must be poured from the original container into another, be sure to clean all possible contaminants from the service container. Always clean the mesh element of the filter and replace the cartridge any time the system oil is changed.
3.While the unit is shut down, a good preventive maintenance measure is to make a thorough inspection of all hydraulic components, lines, fittings, etc., as well as a functional check of each system, before placing the machine back in service.
Lubrication Specifications
Specified lubricants, as recommended by the component manufacturers, are always the best choice, however, multi-purpose greases usually have the qualities which meet a variety of single purpose grease requirements. Should any question arise, regarding the use of greases in maintenance stock, consult your local supplier for evaluation. Refer to Section 1 for an explanation of the lubricant key designations appearing in the Lubrication Chart.

Drift is to be measured at the cylinder rod with a calibrated dial indicator. The cylinder oil must be at ambient temperature and temperature stabilized.
The cylinder must have the normal load, which is the normal platform load applied.
If the cylinder passes this test, it is acceptable.
NOTE: This information is based on 6 drops per minute cylinder leakage.
2.5PINS AND COMPOSITE BEARING REPAIR GUIDELINES
Filament wound bearings.
1.Pinned joints should be disassembled and inspected if the following occurs:
a.Excessive sloppiness in joints.
b.Noise originating from the joint during operation.
2.Filament wound bearings should be replaced if any of the following is observed:
a.Frayed or separated fibers on the liner surface.
b.Cracked or damaged liner backing.
c.Bearings that have moved or spun in their housing.
d.Debris embedded in liner surface.
3.Pins should be replaced if any of the following is observed (pin should be properly cleaned prior to inspection):

SECTION 3. CHASSIS & TURNTABLE
3.1SWING BEARING
Turntable Bearing Mounting Bolt Condition
Check
NOTE: This check is designed to replace the existing bearing bolt torque checks on JLG Lifts in service. This check must be performed after the first 50 hours of machine operation and every 600 hours of machine operation thereafter. If during this check any bolts are found to be missing or loose, replace missing or loose bolts with new bolts and torque to the value specified in the torque chart, after lubricating the bolt threads with loctite #271. After replacing and retorquing bolt or bolts recheck all existing bolts for looseness.
Check the frame to bearing. Attach bolts as follows:
1.Elevate the fully retracted boom to 70 degrees (full elevation).
2.At the positions indicated on Figure 3-1., Swing Bearing Bolt Feeler Gauge Check, try and insert the 0.0015" feeler gauge between the bolt head and hardened washer at the arrow indicated position.
3.Assure that the 0.0015" feeler gauge will not penetrate under the bolt head to the bolt shank.
4.Swing the turntable 90 degrees, and check some selected bolts at the new position.
5.Continue rotating the turntable at 90 degrees intervals until a sampling of bolts have been checked in all quadrants.
Check the turntable to bearing. Attach bolts as follows:
1.Elevate the fully retracted boom to 70 degrees (full elevation).
2.At the positions indicated on Figure 3-1., Swing Bearing Bolt Feeler Gauge Check, try and insert the 0.0015" feeler gauge between the bolt head and hardened washer at the arrow indicated position.
3.Lower the boom to horizontal and fully extend the boom.
4.At the position indicated on Figure 3-1., Swing Bearing Bolt Feeler Gauge Check, try and insert the
0.0015" feeler gauge between the bolt head and hardened washer at the arrow indicated position.
.0015" Feeler Gauge
Figure 3-1. Swing Bearing Bolt Feeler Gauge Check
Bearing Wear Tolerance
1.From the underside of the machine, at rear center, with the boom fully elevated and fully retracted (Figure 3-2., Swing Bearing Tolerance Boom Placement), measure and record the distance between the swing bearing and the frame using a magnetic base dial indicator. (Figure 3-2., Swing Bearing Tolerance Boom Placement)
2.At the same point, with the boom at horizontal and extended until red marking band on mid section is exposed, measure and record the distance between the swing bearing and frame using a magnetic base dial indicator. (Figure 3-2., Swing Bearing Tolerance Boom Placement)
3.If a difference greater than 1.625 mm (0.064 in.) is determined, the swing bearing should be replaced.
4.If a difference less than 1.625 mm (0.064 in.) is determined, and any of the following conditions exist, the bearing should be removed, disassembled, and inspected for the following:
a.Metal particles in the grease.
b.Increased drive power required.
c.Noise.
d.Rough rotation.
