Across ten sections plus a part-number index, this JLG E300AJ and E300AJP illustrated parts manual covers the full parts structure of both models. The Frame chapter handles steering, hubs, wheel drives, motors and battery boxes. The Turntable chapter covers the hydraulic power unit, both main and boom valve banks, swing drive, ground controls and charger. The Boom chapter documents the base, fly, tower and jib structures together with the rotator assemblies and power track. Platform chapter covers consoles, controllers, footswitch and the SkyGuard, SkyEye and SkyLine systems. The Cylinder chapter breaks down every hydraulic cylinder into its individual serviceable items with seal kits, and the Hydraulic and Electrical chapters provide complete system diagrams with every hose, fitting, cable and connector listed. Each figure contains an item number, part number, quantity, description and reference-revision column that ties directly to the associated exploded illustration.

What This Parts Manual Lets You Do

With the correct exploded view in hand, ordering the right JLG part becomes straightforward. You can identify the exact part number for a failed drive motor sensor, a leaking cylinder seal kit, a specific cartridge valve inside the main valve block, a boom harness connector, or a decal that has worn off. The quantity column tells you how many are used per assembly, so you do not under-order fasteners, washers or O-rings. The reference (Ref) and revision (Rev) columns flag assemblies that must be purchased complete and parts that have been superseded.

For fleet owners, the Recommended Service Parts Stock list in Section 9 is particularly valuable – it identifies the field-repairable items that should be kept on the shelf so a machine is not down waiting for a small component. The Special Options section is equally useful when a machine has been ordered with factory or dealer-installed extras that need replacement parts.

Why Correct Part Numbers Matter

JLG electric boom lifts use many look-alike components that differ only by model, spec region (ANSI, CE, CSA, UL, Australian, Japanese) or serial range. Ordering the wrong cartridge for the main valve, the wrong harness connector for the platform box, or a battery cable kit built for a different battery set wastes time and money. This JLG E300AJ & E300AJP Illustrated Parts Manual 31215002 Rev A ties every part to a specific figure and a specific model/spec, so the number you read is the number you order.

Instant PDF Delivery

The manual is delivered as a downloadable PDF immediately after purchase – no shipping, no waiting for a physical book. Open it on a phone, tablet, laptop or desktop, search by part number or figure number, zoom the exploded views, and print only the pages you need for the workshop. Once downloaded, it is yours to keep and reference whenever a part needs replacing.
