MAINTENANCE 8.1 8.1.2 SERVICE ACCESS 1. 2A Boom Support For safety while performing regular service or mainte- nance work, the loader is equipped with boom support pins. The boom support pins when extended prevent the boom arms from dropping if hydraulic pressure is relieved or the hydraulic controls are accidentally cycled. IMPORTANT Fully retract boom support pins before raising or lowering boom arms. C729 To operate the boom support, first remove any bucket or attachment from the quick - tach; raise the boom arms to full height. Raise the boom support handle (fig. C729) up and push out toward boom arms to extend the boom sup- port pins (fig.
C694) Slowly lower the boom arms down on to the pins. WARNING To avoid personal injury: Do not leave boom arms up unless the boom supports are engaged. C694 1. 2B Seat Removal The seat and seat plate can be removed to provide access to the controls, hydraulic and hydrostatic components. To remove the seat assembly, remove the fasteners located at the front of the seat. BE SURE TO DISCONNECT THE ELECTRICAL PLUG! Lift the seat assembly out of the machine. When installing the seat, be sure the seat plate is locked in place at the rear (fig. C806). Electrical Plug C806 8 1. 2C Hydrostatic Shield Fasteners The hydrostatic shield can be by removing the two (2) fasteners (fig.C2358).
