GENERAL OPERATION
Operation - 37
Turning Radius
The 4520 power unit has three mounting positions for
the steering cylinder that determine the power unit’s
turning radius.
1.
1
2
3
Standard position:
this position is the standard
position and enables the tightest turning radius.
2.
Dual wheel position:
the steering cylinder must
be installed in this position when operating with
dual wheels. The resulting turning radius is larger
than position number 1.
3.
Cab and Versa-loader position:
the steering cyl-
inder must be installed in this position when a cab
is installed or when operating the Versa-loader.
The resulting turning radius is larger than position
number 2.
Roll-Over Protection System
WARNING
Keep the ROPS locked in the upright position and
the seat belt securely fastened during operation.
Failure to do so could result in serious injury or loss
of life.
The 4520 power unit is equipped with a fold down
ROPS that allows the power unit to access areas of low
overhead clearance. Lower the roll bar only when ab-
solutely necessary and raise the roll bar to the upright
position as soon as clearance allows.
WARNING
Do not wear a seat belt when the roll bar has been
lowered to the down position.
To lower the roll bar:
1. Remove the pins from the right and left hinge
plates (1).
2. Fold the roll bar down and install the pins in the
hinge plates (2) to lock in place.
