Seat Adjustment for Operator Weight
CAUTION
A major cause for high Whole Body Vibration is
caused by the operator not adjusting the seat to
his/her weight.
NOTE: It is important to adjust the weight setting
for each operator.
NOTE: The seat is designed for a maximum weight
of 135 kg (298 lb).
The target is for the "ride indicator" to fall
between the arrows when the operator sits
upright on the seat with the feet positioned
on the pedals. This ensures that the operator
is set at the midpoint of the 80 mm (3.5 in.)
suspension. See Figure 11.
The weight adjustment handle can be turned
as shown to increase or decrease the weight
resistance Pull handle out before turning. As
handle is turned the "stiffness" of the sus-
pension can be felt to increase or decrease
depending on which way the handle is
turned.
