OPERATION

CAB AND GUARDS

The cab offers the operator the option of a controlled environment as well as the safety of the ROPS (rollover protective struc-
ture). The guards equipped with the machine are there to protect all personnel from injury due to contact with moving or hot
parts. It is important that all these structures be kept in good condition and replaced if damaged.

CAB

DOORS AND WINDOWS

On the cab, the rear upper window (1) of the cab can be opened com-
pletely. When open, the window is positioned and secured under the
roof. The lower window is fixed in place. When raising the upper win-
dow, be sure it is securely latched in place. Doing so will prevent the
window from suddenly falling during operation.
The rear cab doors (1) can be operated only after releasing the couplings
(2), by pulling and lifting the window itself.
Once the window has been positioned, the bayonet joints (2) must be fit-
ted into the upper safety couplings.
The side windows can be opened after releasing safety lock (8). There-
fore, proceed in the following sequence:
Press button (9) to release safety lock (8), then lock lever (3).
To open the side windows completely:
Rotate the window completely and engage couplings (4) in the elastic
blocks (5) provided on the door.
When closing the side window, always engage safety lock (8) by press-
ing button (10)
Remark
The side window must always be secured in the open position with the locks (5) or they must remain closed.
When the windows are closed, always secure them with the safety device block (8). Periodically lubricate the
elastic locks (5) with the specified grease.
