INTRODUCTION - MAINTENANCE SAFETY PRECAUTIONS

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 electrical, 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.

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 torelieve any system pressure prior to disconnecting or removing any portion of the system.

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.

• 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 SERVICE MANUAL.

• KEEP OIL, GREASE, WATER, ETC. WIPED FROM STANDING SURFACES AND HAND HOLDS.

•USE CAUTION WHEN CHECKING A HOT, PRESSURIZED COOLANT SYSTEM.

SINCE THE MACHINE MANUFACTURER HAS NO DIRECT CONTROL OVER THE FIELD INSPECTION AND MAINTENANCE, SAFETY IN THIS AREA IS THERESPONSIBILITY OF THE OWNER/OPERATOR.

• 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 DISCONNECTED DURING REPLACEMENT OF ELECTRICAL COMPONENTS.

• KEEP ALL SUPPORT EQUIPMENT AND ATTACHMENTS STOWED IN THEIR PROPER PLACE.

• USE ONLY APPROVED, NONFLAMMABLE CLEANING SOLVENTS.

eign 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.

Components Removal and Installation

IT IS GOOD PRACTICE TO AVOID PRESSURE-WASHING ELECTRICAL/ELECTRONIC COMPONENTS. IN THE EVENT PRESSURE-WASHING THE MACHINE IS NEEDED, ENSURE THE MACHINE IS SHUT DOWN BEFORE PRESSURE-WASHING. SHOULD PRESSURE WASHING BE UTILIZED TO WASH AREAS CONTAINING ELECTRICAL/ELECTRONIC COMPONENTS, JLG INDUSTRIES, INC. RECOMMENDS A MAXIMUM PRESSURE OF 750 PSI (52 BAR) AT A MINIMUM DISTANCE OF 12 INCHES (30.5 CM) AWAY FROM THESE COMPONENTS. IF ELECTRICAL/ELECTRONIC COMPONENTS ARE SPRAYED, SPRAYING MUST NOT BE DIRECT AND BE FOR BRIEF TIME PERIODS TO AVOID HEAVY SATURATION.

1. The most important single item in preserving the long service life of a machine is to keep dirt and for-

2-2 – JLG Lift– 3121824

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°.

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.

SECTION 2 - GENERAL

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.

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.

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.)

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.

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 -29° C (-20° F). However, use of this oil will give poor performance at temperatures above 49° C (120° F). Systems using DTE 13 oil should not be operated at temperatures above 94° C (200° F) under any condition.

Changing Hydraulic Oil

1. Use of any of the recommended 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.

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 -26° C (-15° F) 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

-26° C (-15° F).

2.4 CYLINDER DRIFT TEST

Maximum acceptable cylinder drift is to be measured using the following methods.

Platform Drift

Measure the drift of the platform to the ground. Lower booms (if equipped) slightly elevated, upper boom fully extended with the rated load in the platform and power off. Maximum allowable drift is 2 in. (5 cm) in 10 minutes. If the machine does not pass this test, proceed with the following.

Cylinder Drift

5 127 0.009 0.22

6 152.4 0.006 0.15

7 177.8 0.005 0.13

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 cyl-

inder leakage.

3.1 CALIBRATIONS

Elevation Sensor Calibration (Prior to Software V13.6)

NOTE: Make sure your analyzer is in ACCES LEVEL 1.

When using the analyzer the terms referring to ROTARY & PROXIMITY sensors are ELEV SENSOR & ELEV PROX.

Use ELEV SENSOR sub level menu for rotary switch adjustments.

Use SET ELEV SENSOR top level menu for proximity switch adjustment and final calibrations.

NOTE: If the Always set the rotary switch first before the

proximity switch because they back each other up in the case of a component failure.

1. When mounting, make sure the rotary switch is aligned with the bladed pin mounted on the scissor arm. There must be a preload when installing the rotary switch on the bladed pin bracket, similar to a throttle actuator.

2. There are (3) 3/8 mounting screws that hold the switch onto the scissor arm mounting lug, make sure they are snug, not loose, so you are able to rotate the rotary switch.

3. Make sure the deck is fully lowered. Plug in the analyzer and scroll through DIAGNOSTICS/ELEV SENSOR to ANGLE SNSR. This should read 0.40v -

0.45v.

6. Lift the platform up until it stops lifting, this will be the lift cut-out height.

7. Using the analyzer, press ESCAPE, scroll to DIAGNOSTICS, press ENTER, scroll to ELEV SENSOR and press ENTER. YOu should now see ANGLE SNSR. The setting here should be 0.60v - 0.70v. This is the rotary switch output voltage that is being sent to J2-15 of GEC at the lift cutout mark. A fully elevated platform will read 2.95 volts.

8. Press ESCAPE on the analyzer, scroll to SYSTEM then to ELEV PROX OPEN. Now manually adjust the proximity switch until you see the analyzer read ELEV PROX CLOSED. At this point make sure you have the maximum 5/16 in of clearance between the eye of the proximity switch and the scissor arm. If you don’t, shim it. If everything is okay at this point tighten it down, this setting is required in case the rotary switch fails. The proximity switch is a back up to assure proper lift cut-out.

NOTE: If the gap ever increases beyond 5/16 in., the switch

may cause intermittent operation.

9. Completely lower the platform. Using the analyzer press escape and scroll through DIAGNOSTICS and then go to ELEV SENSOR, press ENTER. Check to see that the following items are reading correctly.

ANGLE SNSR 0.40 - 0.45

ZEROED 0.00V

SENSOR OK

STOWED? YES

ELEVATED? NO

NOTE: Anytime the ground control board or if the rotary sen-

sor is replaced the rotary sensor must be reset (zeroed out).

4. If the reading is not within the spec, adjust the rotary switch by rotating the bracket and viewing the analyzer.

5. Loosen the hardware that holds the proximity switch and allow the switch to drop to the bottom of the slide bracket. Using the analyzer, press escape twice and scroll through ACCESS LEVEL 2. enter the password to get into ACCESS LEVEL 1. Scroll to SET ELEV SENSOR and after pressing ENTER you should hear the motion alarm sounding off. This puts the machine in adjustment mode.

NOTE: If your machine does not have a motion alarm, the

following procedures will still apply.

DRIVE? YES

CALIB 0.40 - 0.45

10. If CALIB; reads whatever you set your rotary switch to (0.40 - 0.45) then press ENTER.

11. Press ESCAPE until you arrive at DIAGNOSTICS, then scroll over to top level menu SET ELV SENSOR, press ENTER, an alarm will sound off if your machine is equipped with one. The analyzer will now ask to SET ELEV SENSOR. At this point press ENTER key. If everything tested properly the analyzer will read COMPLETE.

12. Now lift the machine up until it stops lifting, measure the cutback height;

M3369/3369LE - 8 ft - 9.5 ft (2.4 - 2.9 m)

M4069/4069LE - 9.5 ft - 11.7 ft (2.9 - 3.6 m)

brated.

3. SET 30FT ELEV (3369LE) or SET 36FT ELEV (4069LE);

Tilt Sensor Calibration:

1. Drive the machine onto a measured level surface (±0.5° for both x and y axis).

2. Using the Analyzer, go to MENU: CALIBRATION; TILT SENSOR. Press Enter. LEVEL VEHICLE will display. Press Enter again to calibrate.

3. Both axis’ raw angles need to be within 5.0°, otherwise the machine is to unlevel and the software will prohibit calibration. Should this occur, attempt to dissect the three areas of error to find the primary contributor:

a. Machine mounting and/or grade:

With a digital level, measure the top of the Ground Control box for levelness. If unable to get a good reading, check the box’s mounting surface for levelness.

a. Raise platform to a height of 30 feet on the

3369LE or 36 feet for the 4069LE (measured deck to ground).

b. Enter YES on the Analyzer.

c. COMPLETE will show on the analyzer when cali-

brated.

NOTE: Elevation Proximity Switch must be mounted and

functioning properly to calibrate the Elevation Sensor.
