JLG Boom Lift E300AJ

- Hydraulic Tank Oil Level Change

NOTE! On new machines, those recently overhauled, or after changing hydraulic oil, operate all systems a minimum of two complete cycles and recheck oil level in reservoir

- Wheel Drive Hub Oil Level Change

1. Lubricate the wheel bearings;

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

WARNING! WHEEL NUTS MUST BE INSTALLED AND MAINTAINED AT THE PROPER TORQUE TO PREVENT LOOSE WHEELS, BROKEN STUDS, AND POSSIBLE DANGEROUS SEPARATION OF WHEEL FROM THE AXLE. BE SURE TO USE ONLY THE NUTS MATCHED TO THE CONE ANGLE OF THE WHEEL

Tighten the lug nuts to the proper torque to prevent wheels from coming loose. Use a torque wrench to tighten the fasteners. If you do not have a torque wrench, tighten the fasteners with a lug wrench, then immediately have a service garage or dealer tighten the lug nuts to the proper torque. Over-tightening will result in breaking the studs or permanently deforming the mounting stud holes in the wheels. The proper procedure for attaching wheels is as follows

1. Start all nuts by hand to prevent cross threading. DO NOT use a lubricant on threads or nuts

- Hydraulic Tank Oil Level Check

NOTE: To avoid excessive battery charging time, do not allow batteries to become completely discharged. 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

1. Charge batteries at the end of each work day, or when machine performance is significantly reduced due to batteries becoming discharged

2. Charge batteries in accordance with the following procedure

a. Open battery compartment, and battery charger compartment covers

WARNING! WHEN BATTERY CHARGER IS TO BE USED, CHARGING HARNESS MUST BE PLUGGED INTO A GROUNDED RECEPTACLE. IF RECEPTACLE IS NOT GROUNDED AND A MALFUNCTION SHOULD OCCUR, THE MACHINE COULD CAUSE SERIOUS ELECTRICAL SHOCK

b. Remove charging harness cable and connect to a receptacle or the correct voltage

NOTICE! LUBRICATION INTERVALS ARE BASED ON MACHINE OPERATION UNDER NORMAL CONDITIONS. FOR MACHINES USED IN MULTI-SHIFT OPERATIONS AND/OR EXPOSED TO HOSTILE ENVIRONMENTS OR CONDITIONS, LUBRICATION FREQUENCIES MUST BE INCREASED ACCORDINGLY

1. Apply grease and rotate in 90 degree intervals until bearing is completely lubricated

- Wheel Drive Hub Oil Level Check

1. Check torque every 3 months or 150 hours of operation;

- Hydraulic Return Filter Change

1. Change the filter when Boom Lift is new

1. Wheel nuts should be torqued after first 50 hours of operation and after each wheel removal;
