8. Seat Belt
The seat belt is for the operator's safety and should
always be worn. Before driving the machine, adjust the
seat to the desired position for maximum comfort and
machine control, then fasten the seat belt. Seat belts
must be worn across the pelvic region and adjusted
snugly to lessen the chance and severity of injury in
case of an accident. Never fasten a seat belt across the
abdomen.
Under no circumstances should the operator be
standing in the cabin when operating the excavator.
Do not adjust the seat position while the vehicle is
moving because a loss of control may result. Stop the
machine, apply the parking brake, and then adjust the
seat.
Always, check the condition of seat belt and belt
bracket before fastening it. Do not use it with twists in
it. Replace belt or bracket if damaged or worn.
Seat Belt Locking and Unlocking
Insert belt end (1, Figure 140) into the buckle (2). Pull the
belt to check that belt end is locked into buckle.
Adjust belt length so that it comfortably tight against the
operator's pelvic region (hipbone).
Press the button (3, Figure 141) in the center of buckle (2)
and pull out belt (1) to unlock.
