The hostile environment package provides additional pro-
tection against the entry of dust, dirt, sand and other abra-
sive materials into the hydraulic system, control handles
and switches, cylinders, boom wire ropes and wear pads,
and the air inlet of the engine. The package is intended for

other similar hostile conditions. The hostile environment

A motion alarm horn provides an audible warning when
the platform controls are selected at the PLATFORM/
GROUND SELECT switch, the POWER/EMERGENCY
STOP switch is ON, and the footswitch is depressed. The
alarm warns personnel in the jobsite area to avoid the
operating machine.

The semi-track option consists of steel tracks and idler
wheels. The idler wheels are mounted to the chassis just
forward of the drive wheels. The steel tracks are installed
around the drive wheels and idler wheels. This option pro-
vides increased traction for operation in rough terrain.
