Track Excavator Safety

Page 25

•

Clear all obstacles from the machine's path. Beware
of hazards.

•

Be sure that all windows are clean. Secure the doors
and the windows in the open position or in the shut
position.

•

Adjust the rearview mirrors for best visibility close to
the machine. Make sure that the horn, the travel
alarm (if equipped), and all other warning devices are
working properly.

•

Fasten the seat belt securely.

•

Warm up the engine and hydraulic oil before
operating machine.

•

Before moving the machine, check undercarriage
position. The normal travel position is with idler
wheels to the front under the cabin and the drive
sprockets to the rear. When the undercarriage is in
the reversed position, the travel controls must be
operated in opposite directions.
