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.
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. C693) 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.
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. 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.
The hydrostatic shield can be by removing the fasteners
(fig.C3557).
